Technical Field

Embodiments of the present invention relate to the field of communications technologies, and in particular, to a communication method, an apparatus, and a computer-readable storage medium.

Background

Satellite communication is communication performed between radio communication stations on earth (including the ground and the lower atmosphere) using a satellite as a relay. The satellite communication system consists of two parts, a satellite and an earth station. The characteristics of satellite communication: the communication range is large; communication can be performed from any two points as long as the range covered by the electric wave transmitted by the satellite is covered; the device is not easily affected by land disasters (high reliability); the earth station circuit can be switched on (the circuit is switched on quickly) only by setting the earth station circuit; meanwhile, the system can receive at multiple places, and can economically realize broadcasting and multiple access communication (multiple access characteristic); the circuit is very flexible in arrangement, and excessively centralized telephone traffic can be dispersed at any time; the same channel can be used for different directions or different intervals (multiple access). In satellite communication, many satellites are not relatively static with respect to the ground, that is, the positions of the satellites and the ground are constantly changed, and problems and faults in a network need to be detected and optimized in order to ensure that terminal equipment can normally communicate. In order to detect and optimize problems and faults in the network, the terminal equipment needs to perform measurement and reporting. The operator can measure and report through the commercial terminal equipment of the subscriber so as to automatically collect the measurement data of the terminal equipment. The measurement and report of the terminal equipment can affect the transmission of the data of the terminal equipment and the service time of the electric quantity of the terminal equipment, so that the communication service quality of the terminal equipment is reduced.

Disclosure of Invention

The embodiment of the invention discloses a communication method, a communication device and a computer readable storage medium, which are used for improving the communication service quality of terminal equipment.

The first aspect discloses a communication method, which may be applied to a terminal device and may also be applied to a module (e.g., a chip) in the terminal device, and the following description will be given by taking the application to the terminal device as an example. The method can comprise the following steps: the terminal equipment determines a filtering condition, wherein the filtering condition is a condition for not measuring and/or reporting; measuring according to the filtering condition; and reporting the measurement result to the network equipment according to the filtering condition.

In the embodiment of the invention, under the condition that problems and faults in the network need to be detected and optimized, the terminal equipment can not measure and/or report the information meeting the filtering condition, and only measure and/or report the information not meeting the filtering condition. Therefore, all information does not need to be measured and/or reported, the information measured and/or reported by the terminal equipment can be reduced, the influence of the measurement and/or reporting of the terminal equipment on the data transmission of the terminal equipment can be reduced, and the communication service quality of the terminal equipment can be improved. In addition, because the information measured and/or reported by the terminal equipment is reduced, not only the time-frequency resource can be saved, but also the electric quantity of the terminal equipment can be saved, and the communication service quality of the terminal equipment can be further improved. Furthermore, the information measured and/or reported by the terminal equipment is reduced, so that the information to be processed by the network equipment is reduced, the resources and the electric quantity of the network equipment can be saved, and the communication service quality of the network equipment can be improved.

As a possible implementation manner, the terminal device determines the filtering condition, which may be that the terminal device receives the filtering condition from the network device, or that the terminal device obtains the filtering condition.

In the embodiment of the present invention, the filtering condition may be configured by the network device, so that the terminal device may not perform measurement and/or report based on the filtering condition configured by the network device. The filtering condition can also be generated by the terminal equipment, and the terminal equipment can autonomously generate the filtering condition which is not measured and/or reported, so that the autonomy of the terminal equipment can be improved.

As a possible implementation manner, before the terminal device acquires the filtering condition, the filtering condition may be generated according to information that can be acquired by the terminal device.

In the embodiment of the invention, the terminal equipment generates the filtering condition according to the information which can be acquired by the terminal equipment, so that the rationality of the filtering condition generated by the terminal equipment can be ensured.

As a possible implementation, the information that can be acquired by the terminal device may include one or more of time information, geographical location information, signal strength, capability information of the terminal device, and a type of the terminal device.

As a possible implementation, the filtering conditions may include one or more of the following: not measuring and/or reporting the specific time or the specific time period; not measuring and/or reporting the specific geographical position; not measuring and/or reporting a specific event; not measuring and/or reporting a specific cell; under the condition that the terminal equipment is in the energy-saving state, the measurement and/or the report are not carried out; under the condition that the terminal equipment is the terminal equipment of the Internet of things, measurement and/or reporting are not carried out; and under the condition that the electric quantity of the terminal equipment is less than or equal to the threshold value, not measuring and/or reporting.

In the embodiment of the present invention, it can be determined that the coverage area of the satellite changes at a certain geographic location on the ground at a certain time or a certain time period according to information such as an ephemeris of the satellite, so that a handover failure (HOF), a Radio Link Failure (RLF), a Random Access Channel (RACH), an RRC establishment failure, an RRC recovery failure, and the like may occur to the terminal device at the geographic location on the ground at the time or the time period. Because the networking in the satellite network is constantly changing, the frequency of the events is much higher than that of the ground network. The more important reason is that during the handover between two satellites, that is, at the moment when the satellite a changes to the area that the satellite B originally covers due to the fact that the satellite a flies into the area that the terminal device cannot cover, the terminal device has a high probability of one or more of HOF, RLF, RACH anew, RRC establishment failure, RRC recovery failure, and the like due to the very fast flight speed of the non-stationary satellite, for example, 7 km/s. Also, because of the fast flight speed of non-geostationary satellites, the connection time of a particular satellite to the terminal device is short, e.g., 15 seconds. Therefore, if the existing mechanism is still used in the non-terrestrial network (NTN), the terminal device will spend a lot of time and signaling to report these events to optimize the network. The quality of satellite communication is greatly deteriorated. Because the time and the position of the handover between the two satellites can be predicted in advance by means of ephemeris and the like, the network device or the terminal device can determine the time or the geographical position in the time period as the filtering condition, so that the terminal device does not need to measure and/or report when the time or the time period is in the geographical position, thereby reducing the occupation of a large amount of time-frequency resources, saving the electric quantity of the terminal device, and improving the communication service quality of the terminal device. In addition, because various events can repeatedly occur when the two satellites are handed over, the filtering mechanism can also enable the network equipment not to process a large number of repeated reports, so that the resources and the electric quantity of the network equipment can be saved, and the communication service quality of the network equipment can be improved. As can be seen from the above description, in the above process, the terminal device has a high probability of generating one or more of the HOF, the RLF, the RACH, the RRC establishment failure, the RRC recovery failure, and the like, and therefore, the network device or the terminal device may determine these events as filtering conditions, so that the terminal device does not measure and/or report these events, thereby reducing occupation of a large amount of time-frequency resources, and saving power of the terminal device, thereby improving service quality of terminal device communication. In addition, because various events can repeatedly occur when the two satellites are handed over, the filtering mechanism can also enable the network equipment not to process a large number of repeated reports, so that the resources and the electric quantity of the network equipment can be saved, and the communication service quality of the network equipment can be improved. Under the condition that the measurement object is a specific cell such as a cell projected by a satellite, the terminal equipment may generate HOF, RLF, RACH, RRC establishment failure, RRC recovery failure, and the like due to movement of the satellite and the like, and therefore, the measurement object can be determined as the specific cell as the filtering condition, so that when the terminal equipment is in the cells, measurement and/or reporting are not required, thereby reducing occupation of a large amount of time-frequency resources, and simultaneously saving the electric quantity of the terminal equipment, thereby improving the service quality of communication of the terminal equipment. In addition, because various events can repeatedly occur when the two satellites are handed over, the filtering mechanism can also enable the network equipment not to process a large number of repeated reports, so that the resources and the electric quantity of the network equipment can be saved, and the communication service quality of the network equipment can be improved. When the terminal device is in the energy-saving state and the terminal device is the internet of things terminal device or the terminal device has less electric quantity, the terminal device performs measurement and/or reporting, and the damage to the terminal device is large, for example, the terminal device may not have enough electric quantity to support positive data transmission, and the like.

As a possible implementation, the measurement may be Minimization Drive Test (MDT), Self Organization Network (SON), MDT and SON. Further, the measurement may be other than the above measurement, and is not limited herein.

A second aspect discloses a communication method, which may be applied to a network device and may also be applied to a module (e.g., a chip) in the network device, and is described below by taking the application to the network device as an example. The method can comprise the following steps: the network equipment determines the filtering condition of the terminal equipment, wherein the filtering condition is a condition for not measuring and/or reporting; and sending the filtering condition to the terminal equipment, wherein the filtering condition is used for indicating the terminal equipment to measure and/or report according to the filtering condition.

In the embodiment of the invention, the terminal equipment can not measure and/or report the information meeting the filtering condition and only measure and/or report the information not meeting the filtering condition under the condition of needing to detect and optimize the problems and faults in the network according to the indication of the network equipment. Therefore, the terminal equipment does not need to measure and/or report all information, the information measured and/or reported by the terminal equipment can be reduced, the influence of the measurement and/or reporting of the terminal equipment on the data transmission of the terminal equipment can be reduced, and the communication service quality of the terminal equipment can be improved. In addition, because the information measured and/or reported by the terminal equipment is reduced, not only the time-frequency resource can be saved, but also the electric quantity of the terminal equipment can be saved, and the communication service quality of the terminal equipment can be further improved. Furthermore, the information measured and/or reported by the terminal equipment is reduced, so that the information to be processed by the network equipment is reduced, the resources and the electric quantity of the network equipment can be saved, and the communication service quality of the network equipment can be improved.

In the embodiment of the invention, the network equipment generates the filtering condition according to the information which can be acquired by the terminal equipment, so that the rationality of the filtering condition generated for the terminal equipment by the network equipment can be ensured.

As a possible implementation, the information that can be acquired by the terminal device may include one or more of time information, geographical location information, signal strength, capability information of the terminal device, and a type of the terminal device.

As a possible implementation, the filtering conditions may include one or more of the following: not measuring and/or reporting the specific time or the specific time period; not measuring and/or reporting the specific geographical position; not measuring and/or reporting a specific event; not measuring and/or reporting a specific cell; under the condition that the terminal equipment is in the energy-saving state, the measurement and/or the report are not carried out; under the condition that the terminal equipment is the terminal equipment of the Internet of things, measurement and/or reporting are not carried out; and under the condition that the electric quantity of the terminal equipment is less than or equal to the threshold value, not measuring and/or reporting.

In the embodiment of the present invention, it can be determined that the coverage area of the satellite changes at a certain time or a certain time period at a certain geographic location on the ground according to information such as an ephemeris of the satellite, so that terminal equipment at the geographic location on the ground at the time or the time period may have HOF, RLF, RACH, RRC establishment failure, RRC recovery failure, and the like.

When the terminal device is in an energy-saving state, the terminal device is an internet of things terminal device or the terminal device has less electric quantity, the terminal device performs measurement and/or reporting, the damage to the terminal device is large, if the terminal device may not have enough electric quantity to support positive data transmission and the like, and the network device is not completely aware of the state of the terminal device, so that one or more of the terminal device in the energy-saving state, the terminal device is the internet of things terminal device, the terminal device has electric quantity less than or equal to a threshold value and the like can be determined as a filtering condition, so that the terminal device can not perform measurement and/or reporting and preferentially process important services, such as data transmission, conversation and the like, under the condition that the terminal device is not suitable for measurement and/or reporting.

Detailed Description

The embodiment of the invention discloses a communication method, a communication device and a computer readable storage medium, which are used for improving the reliability of terminal equipment communication.

For better understanding of a communication method, an apparatus and a computer-readable storage medium disclosed in the embodiments of the present invention, some terms or concepts of the embodiments of the present invention will be described below.

1. Radio Resource Control (RRC) state

In the New Radio (NR), the RRC state of the terminal device may include an RRC CONNECTED state (RRC _ CONNECTED), an RRC deactivated state or a third state (RRC _ INACTIVE) and an RRC IDLE state (RRC _ IDLE). When the terminal device is in RRC _ CONNECTED, links are established between the terminal device and the base station and between the base station and the core network, and when data arrives at the network, the network can directly transmit the data to the terminal device. When the terminal equipment is in RRC _ INACTIVE, a link is established between the base station and the core network, the link between the terminal equipment and the base station is released, although the link between the terminal equipment and the base station is released, the base station stores the context of the terminal equipment, and when data needs to be transmitted to the terminal equipment, the base station can quickly recover the link between the terminal equipment and the base station according to the context of the terminal equipment. When the terminal device is in the RRC _ IDLE state, there is no link between the terminal device and the base station and between the base station and the core network, and when there is data to be transmitted, it is necessary to establish a link between the terminal device and the base station and between the base station and the core network. Referring to fig. 1, fig. 1 is a schematic diagram illustrating RRC state transition according to an embodiment of the present invention. As shown in fig. 1, when the terminal device is in the RRC connected state, after the links between the terminal device and the base station and between the base station and the core network are released (release), the terminal device will be converted from the RRC connected state to the RRC idle state. When the terminal device is in the RRC idle state, after (establsh) links between the terminal device and the base station and between the base station and the core network are established, the terminal device is converted from the RRC idle state to the RRC connected state. When the terminal device is in the RRC deactivated state, after the link between the base station and the core network is released, the terminal device switches from the RRC deactivated state to the RRC idle state. When the terminal device is in the RRC deactivated state, after a link between the terminal device and the base station is restored (resume), the terminal device will be converted from the RRC deactivated state to the RRC connected state. When the terminal device is in the RRC connected state, after a link between the terminal device and the base station is released (i.e., release with suspension), the terminal device will be switched from the RRC connected state to the RRC deactivated state.

2. Satellite communication

Satellite communication, namely NTN communication, has been the subject of research since the 60's of the 19 th century. Generally speaking, the higher the orbit of the satellite, the larger the coverage area, but the longer the communication delay. Referring to fig. 2, fig. 2 is a schematic diagram of a satellite orbit according to an embodiment of the invention. As shown in fig. 2, the orbit of the satellite can be classified into:

(1) low orbit (LEO): the height of the track is 160 km-2000 km;

(2) medium orbit (MEO): the height of the track is 2000 km-35786 km;

(3) synchronous orbit (GEO-thrones earth orbit, GEO): the height of the orbit is 35786km, and the relative position of the satellite running on the orbit and the earth is not influenced by the rotation of the earth;

(4) high Elliptical Orbit (HEO): is an elliptical orbit with a low near point and a high far point, and the height of the far point is larger than that of the GEO satellite.

The satellite in LEO is close to the ground, the communication time delay is short, the data transmission rate is high, the weight and the volume of the terminal equipment can be almost the same as those of personal mobile equipment, and the satellite is more suitable for mass market popularization and becomes a hotspot of current industrial development.

Referring to fig. 3, fig. 3 is a schematic diagram of a network for satellite communication according to an embodiment of the present invention. As shown in fig. 3, when information is transmitted from a source to a destination, a cellular subnet (cellular subnet) may be used on the ground, a Low Altitude Platform (LAP) subnet may be used at low altitude, a High Altitude Platform (HAP) subnet may be used at high altitude, and a satellite communication subnet may be used in outer space.

3. Measurement mechanism

Mobility management is an important component in wireless mobile communications. Mobility management refers to the generic term of related content involved in order to ensure that the communication link between the network device and the terminal device is not interrupted by the movement of the terminal device. Mobility management can be divided into IDLE state (RRC _ IDLE state) mobility management and CONNECTED state (RRC _ CONNECTED state) mobility management according to the RRC state of the terminal device. The mobility management includes a cell selection/reselection (cell selection/reselection) procedure when the terminal device is in an RRC idle state or an RRC deactivated state, and includes a cell handover (cell handover) procedure when the terminal device is in an RRC connected state. Whether cell selection/reselection or cell handover, is based on the measurement results. Therefore, mobility measurements are the basis for mobility management.

Referring to fig. 4, fig. 4 is a flowchart illustrating mobility measurement according to an embodiment of the present invention. As shown in fig. 4, mobility measurements can be divided into physical layer measurements (i.e., layer 1 measurements) and RRC layer measurements (i.e., layer 3 measurements) according to the involved layers. In physical layer measurements, the terminal device may perform specified types of measurements on the configured measurement resources. For Single Side Band (SSB) based measurement, the terminal device may combine measurement results obtained from multiple SSBs with the same SSB index (index) and Physical Cell Identifier (PCI), obtain a layer 1 measurement result of a beam (beam) level of the SSB corresponding to the SSB index of the cell corresponding to the PCI, and report the layer 1 measurement result to the layer 3. For measurement based on a channel state information reference signal (CSI-RS), the terminal device may combine measurement results obtained on a plurality of CSI-RS resources having the same CSI-RS resource identifier (resource identifier) and PCI to obtain a layer 1 measurement result of a beam level of the CSI-RS resource corresponding to the CSI-RS resource identifier of the cell corresponding to the PCI, and report the layer 1 measurement result to layer 3. The above-described process of combining the measurement results on multiple measurement resources is the so-called layer 1 filtering shown in fig. 4. The specific combining manner may be determined by the terminal device according to the time delay, the accuracy, and the like.

After receiving the beam level measurement result reported by layer 1, layer 3 requires that the terminal device select/combine the layer 1 measurement results of each beam of the same cell to derive the cell level layer 3 measurement result. Layer 3 filtering of the resulting cell-level layer 3 measurements is then also required. Only the measurement result after layer 3 filtering is used to verify whether the reporting trigger condition is satisfied, so as to perform the final reporting.

In addition, according to the configuration, the terminal device may also need to report the layer 3 measurement result of the beam level. At this time, the terminal device may directly perform layer 3 filtering on the layer 1 measurement result of each beam, and then select a measurement result to be reported from the filtered measurement results to report.

The terminal device should verify the reporting trigger condition at least when a new cell-level measurement result is generated. When the reporting trigger condition is satisfied, the terminal device needs to send a measurement report to the network device.

4、MDT

MDT, minimization of drive tests technique. The basic idea of the technology is that an operator can partially replace the traditional drive test work by carrying out measurement reporting through commercial terminal equipment of a subscriber so as to automatically collect the measurement data of the terminal equipment, thereby detecting and optimizing problems and faults in a wireless network. The operator generally needs to make routine network coverage drive tests every month, and some call quality drive tests for specific areas are also made for customer complaints, and the drive tests of the scenes can be replaced by MDT. The measurement types of the existing MDT technology may include the following:

1. signal level measurement: measuring the signal level of the wireless signal by the terminal equipment, and reporting the measurement result to the base station or the base station controller;

2. quality of service (QoS) measurement: the QoS measurement may be performed by the base station, such as measurement of traffic flow, traffic throughput, traffic delay, and the like, or the QoS measurement may be performed by the terminal device, for example, measurement of uplink processing delay, or the QoS measurement may be performed by the base station and the terminal device in combination, for example, measurement of air interface delay, that is, measurement of time from a packet passing through a Service Data Adaptation Protocol (SDAP) layer of the base station to a Packet Data Convergence Protocol (PDCP) layer of the terminal device.

3. Accessibility measurement: the terminal equipment records the information of the RRC connection establishment failure and reports the information to the base station or the base station controller.

MDTs may include logged (logged) MDTs and immediate (immediatate) MDTs. The parameter MDT mainly measures the terminal device in an RRC CONNECTED state (i.e., RRC _ CONNECTED), and the network device may instruct the terminal device to perform real-time measurement and reporting. The measurement may include Radio Resource Management (RRM) measurement, physical layer (PH) measurement, Uplink (UL) PDCP delay measurement, quality of experience (QoE) measurement, wireless fidelity (WiFi) measurement, bluetooth measurement, and the like. The RRM measurement may include a Reference Signal Received Power (RSRP) measurement, a Reference Signal Received Quality (RSRQ) measurement, a Received Signal Strength Indicator (RSSI) measurement, and the like. The parameter MDT is generally used to measure data volume of a terminal device, an Internet Protocol (IP) throughput, packet transmission delay, packet loss rate, processing delay, and the like.

The logged MDT mainly performs measurement for a terminal device in an RRC IDLE state (i.e., RRC _ IDLE) or an RRC deactivated state (i.e., RRC _ INACTIVE). Each Logged record (record) in the Logged MDT measurement result may include a relative time stamp (relative time stamp), an NR Cell Global Identifier (NCGI), a serving cell measurement result, a neighbor measurement result, a Wireless Local Area Network (WLAN) measurement result, a sensor measurement result, and the like. Optionally, each Logged record (record) in the Logged MDT measurement result may further include location information of the terminal device. The serving cell measurement result may include a PCI, a cell RSRP/RSRQ, a best beam index (beam index), an RSRP/RSRQ of a best beam, a number of good beams, and the like. A registered MDT generally refers to a measurement of the received signal strength by a terminal device.

Some L2 measurements are also defined in NR for network device to count some network performance for radio link management, radio resource management, network maintenance, etc. These L2 measurements are statistical for a terminal device, such as the throughput of the service, the traffic flow, the processing delay of the terminal device, and the air interface delay of the terminal device.

The MDT measurement initiated by the base station may be signaling-based MDT (signaling-based MDT) or management-based MDT (management-based MDT). The signaling-based MDT refers to an MDT for a specific terminal device, and a base station receives a message from a Core Network (CN) to perform MDT on the specific terminal device. The MDT based on management is not an MDT for a specific terminal device, and the base station receives a message for performing MDT from Operation Administration and Maintenance (OAM). The base station selects the terminal equipment from the terminal equipment under the base station to perform MDT measurement based on a certain strategy. For signaling-based MDT, the CN does not initiate signaling-based MDT for the terminal device unless the terminal device has agreed to do MDT. For management-based MDT, the base station may consider whether the terminal device agrees to perform MDT when selecting the terminal device, for example, only those terminal devices that have agreed to perform MDT may be selected to perform MDT measurement. For example, the CN may inform the base station whether a certain terminal device agrees to perform MDT. For another example, the CN notifies the base station of a Management-Based MDT Allowed indication (Management-Based MDT Allowed indication) message of the terminal device. Optionally, the CN may also inform the Public Land Mobile Network (PLMN) list based on the managed MDT. Both of these MDTs may include logged MDT and immediated MDT. For MDT based signaling, the CN notifies the base station of some MDT configuration information, Trace Collection Entity (TCE) IP address. The MDT configuration information may include an activation type of MDT, an area range of MDT, a mode of MDT, a configuration parameter of the mode of MDT, a PLMN list of MDT based on signaling, and the like. The activation types of MDT may include immediate-only MDT (immediate MDT only), logged MDT (logged MDT only), immediate-MDT and trace (immediate MDT and trace), and the like. The configuration parameters of the pattern of the MDT may include a measurement event of the immediatate MDT, a logging interval of the logged MDT, a duration of the logged MDT, and the like.

Referring to fig. 5, fig. 5 is a schematic flow chart of a logged MDT according to an embodiment of the present invention. As shown in fig. 5, first, the terminal device performs RRC establishment with the network device. After the RRC establishment procedure is completed, the network device may select a terminal device for the MDT task, and then send a logged MDT configuration (logged MDT configuration) message to the terminal device. That is, when the terminal device is in the RRC connected state, the base station may configure the logged MDT measurement related configuration for the terminal device, and the base station may notify the logged MDT related configuration through an RRC message. And then RRC release is performed. After the RRC release procedure is completed, the terminal device is in an RRC idle state/an RRC deactivated state, and the terminal device performs logged data collection (logged MDT data collection). That is, when the terminal device enters the RRC idle state or the RRC deactivated state, the terminal device records the corresponding measurement result according to the corresponding configuration. And then, performing RRC establishment/recovery, wherein in the RRC establishment/recovery process, the terminal equipment sends a recorded MDT availability indication (logged MDT availability indicator) message to the network equipment. That is, when the terminal device initiates an RRC connection to the network, the RRC message may carry an indication information, where the indication information is used to indicate that the current terminal device records the measurement result of the logged MDT. After the RRC establishment/recovery procedure is completed, the network device may send a UEInformationRequest message to the terminal device. That is, the network device may send a request for acquiring the logged MDT record to the terminal device. After receiving the UEInformationRequest message from the network device, the terminal device may send a UEInformationResponse message to the network device. That is, after receiving the request, the terminal device may report the measurement result of the logged MDT to the network device. For example, the terminal device may carry the indication information in an RRC establishment complete (RRCSetupComplete) message, the network device may request the terminal device to acquire the logged MDT record in a UEInformationRequest message, where the message carries a request indication information for indicating the terminal device to report the logged MDT record to the network device, and then the terminal device reports the logged MDT record to the network device in the UEInformationResponse message. Wherein. The network device that issues the configuration related to the logged MDT measurement to the terminal device may not be the same network device as the network device that reports the measurement result of the logged MDT to the terminal device.

For some streaming services or voice services, such as streaming service (streaming service), IP Multimedia Subsystem (IMS) Multimedia Telephony Service (MTSI) service, etc., the simple signal quality does not reflect the user experience of the user when using these services, so the operator wants to know the user experience, so as to better optimize the network and improve the user experience. Such measurement collections may be referred to as QoE measurement collections, and may also be referred to as application layer measurement collections. Such measurements may be initiated using signaling-based MDT and management-based MDT. After the base station receives the measured configuration information from the CN or OAM, the base station may send the configuration information to the terminal device through an RRC message. The RRC layer of the terminal device may transmit the measurement results of the application layer to the base station after receiving the measurement results from the upper layer of the terminal device. The configuration information sent by the CN or OAM to the base station, and the measurement result sent by the terminal device to the base station, may be sent in the form of a transparent container. The information received by the base station from the CN or OAM may include other information of QoE measurement, such as area coverage of QoE measurement, traffic type of QoE measurement, etc., in addition to the above configuration information of measurement. The method for selecting the terminal equipment by the base station to perform the QoE measurement is basically the same as the common MDT measurement. For QoE measurement, the network device may configure a Signaling Radio Bearer (SRB), such as SRB4, for the terminal device to transmit the QoE measurement result. The terminal equipment can report the QoE measurement result through the signaling bearer. The network device that issues the QoE measurement related configuration to the terminal device and the network device that reports the QoE measurement result from the terminal device may not be the same network device. Referring to fig. 6, fig. 6 is a flow chart illustrating QoE measurement according to an embodiment of the present invention. As shown in fig. 6, the network device may send the QoE configuration to the terminal device, which sends a QoE measurement report to the network device.

5、SON

The SON does not need to add network equipment, and can make maximum use of the existing equipment so as to reduce operation cost.

The SON mainly includes Automatic Neighbor Relation (ANR), PCI allocation (selection), Mobility Robustness Optimization (MRO), Mobility Load Balancing (MLB), Energy Saving (ES), MDT, and capacity optimization (CCO).

For the utilization of the device, maximization and high performance are addressed. For example, the coverage optimization may be accomplished by load balancing, coverage capacity optimization, without adding new devices, and mobility optimization, random access optimization, etc. may be utilized to achieve a greater performance improvement with existing devices.

For cost, the requirement can be met by reducing the number of operation and maintenance personnel and reducing the skill of the operation and maintenance personnel. The MDT technology can be used for reducing the cost of the artificial road side, and the ES technology can be used for achieving the effect of energy saving. The performance of the system may be improved by an automated maintenance process.

The ultimate goal of SON technology is to achieve complete automation of network planning and optimization, thereby achieving a truly self-organizing network.

SON is a method of continuously and automatically optimizing network configuration parameters through automatically generated configuration parameters.

In the third generation partnership project (3 GPP), some use cases (use cases) for SON research are defined. The use cases defined by 3GPP may include ANR, PCI selection, MRO, MLB, ES, MDT, coverage, CCO, and the like.

In NR, some use cases for SON studies are also defined. The use cases defined by NR may include MRO, PCI select, MLB, ES, MDT, CCO, and the like. In addition, NR introduces some new functions, such as vehicle to everything (V2X) SON, etc.

In order to better understand a communication method, a communication device, and a computer-readable storage medium disclosed in the embodiments of the present invention, a network architecture used in the embodiments of the present invention is described below. The communication method, the apparatus, and the computer-readable storage medium disclosed in the embodiments of the present invention may be applied to various NTN-based communication systems, such as a fourth generation mobile communication technology (4G) communication system based on NTN, a fifth generation mobile communication technology (5G) communication system based on NTN, a future NTN-based communication system, and the like. Five Radio Access Network (RAN) device architectures based on NTN are defined in the existing communication standards. Referring to fig. 7, fig. 7 is a schematic diagram of a network architecture according to an embodiment of the present invention. Among them, the network architecture shown in fig. 7 adopts a RAN architecture with transparent satellite (RAN architecture). As shown in fig. 7, the network architecture may include a terminal device 701, a RAN device 702, a core network device 703, and a Data Network (DN) 704. The RAN equipment 702 may include a Remote Radio Unit (RRU) and a base station. The RRU may include a satellite and an NTN gateway (gateway). Terminal equipment 701 may access the base station through a satellite and an NTN gateway. In which, in transparent (transparent) scenarios, satellites are used for radio frequency filtering (radio frequency filtering) and frequency conversion and amplification (frequency conversion and amplification) in order to ensure that the waveform signal of the payload repetition remains unchanged (the waveform repeated by the payload is un-changed). I.e. the satellite acts primarily as a relay device at the L1 level (L1 relay) for regenerating the physical layer signals, which are not visible at the upper level.

Referring to fig. 8, fig. 8 is a schematic diagram of another network architecture according to the embodiment of the present invention. Among them, the regenerative (regenerative) satellite in the network architecture shown in fig. 8 does not have an inter-satellite link (ISL), and the base station processes the payload. As shown in fig. 8, the network architecture may include a terminal device 801, a RAN device 802, a core network device 803, and a DN 804. RAN equipment 802 includes base stations and NTN gateways, with satellites as base stations. The satellite and the NTN gateway are connected through a Satellite Radio Interface (SRI).

Referring to fig. 9, fig. 9 is a schematic diagram of another network architecture according to the embodiment of the present invention. Here, the regenerated satellite in the network architecture shown in fig. 9 has ISL, and the base station processes the payload. As shown in fig. 9, the network architecture may include a terminal device 901, a RAN device 902, a core network device 903, and a DN 904. In this scenario, the satellite also acts as a base station. The difference between the scenario corresponding to fig. 8 is that the scenario has an ISL.

Referring to fig. 10, fig. 10 is a schematic diagram of another network architecture according to the embodiment of the present invention. As shown in fig. 10, the network architecture may include a terminal device 1001, a RAN device 1002, a core network device 1003, and a DN 1004. The RAN device 1002 includes a Distributed Unit (DU) and a Central Unit (CU). The satellite acts as a DU for the RAN equipment 1002.

In a fifth NTN-based RAN equipment architecture defined in the communication standard, a base station processes a payload (gNB processed payload based on relay-like architecture) based on a relay class architecture. The satellite acts as an Integrated Access and Backhaul (IAB).

The terminal device may be a wireless terminal device or a wired terminal device. A wireless terminal device may be a device that provides voice and/or data connectivity to a user, may be a handheld device with wireless connection capability, or other processing device connected to a wireless modem. The wireless terminal device may communicate with one or more core network devices via the RAN device. The wireless terminal device may be a mobile terminal device, for example, a mobile phone (or referred to as a "cellular" phone) and a computer having the mobile terminal device. Also for example, mobile devices, which may be portable, pocket, hand-held, computer-included, or vehicle-mounted, exchange language and/or data with a radio access network. For another example, the wireless communication device may be a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), or the like. A wireless terminal device may also be referred to as a system, a Subscriber Unit (SU), a Subscriber Station (SS), a mobile station (MB), a mobile station (mobile), a Remote Station (RS), an Access Point (AP), a Remote Terminal (RT), an Access Terminal (AT), a User Terminal (UT), a User Agent (UA), a User Device (UD), or a user terminal (UE).

The RAN device is mainly responsible for functions of radio resource management, QoS management, data compression, encryption, and the like on the air interface side. The RAN equipment may include various forms of base stations, such as: macro base stations, micro base stations (also referred to as small stations), relay stations, access points, etc. The AN device allows the terminal device and the 3GPP core network to use a non-3 GPP technology for interconnection and interworking, where the non-3 GPP technology may be wireless fidelity (Wi-Fi), Worldwide Interoperability for Microwave Access (WiMAX), Code Division Multiple Access (CDMA) network, and the like.

The RAN equipment may be CU and DU separated or centralized. The RAN device is connected to the core network device. The core network device may be a core network device in Long Term Evolution (LTE), may also be a core network device in 5G, and may also be a core network device in other communication systems.

Referring to fig. 11, fig. 11 is a schematic structural diagram of a RAN device with separate CUs and DUs according to an embodiment of the present invention. As shown in fig. 11, the RAN equipment may include CUs and DUs. CUs and DUs can be understood as the division of RAN equipment from a logical functional point of view. CUs and DUs may be physically separate or deployed together. A CU may control the operation of one or more DUs. A DU may also connect multiple CUs (not shown). The CU and the DU may be connected to each other via an interface, for example, via an F1 interface. CUs and DUs may be partitioned according to protocol layers of the wireless network. As a possible division, the CU is used to perform functions of an RRC layer, a DAP layer, and a PDCP layer, and the DU is used to perform functions of a Radio Link Control (RLC) layer, a Medium Access Control (MAC) layer, a physical (physical) layer, and the like. It is to be understood that the division of CU and DU processing functions according to such protocol layers is merely an example, and may be performed in other manners. A CU or DU may be partitioned to have more protocol layer functionality. For example, a CU or DU may also be divided into partial processing functions with protocol layers. In one possible embodiment, part of the functions of the RLC layer and the functions of the protocol layers above the RLC layer may be provided on the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer may be provided on the DU. In one possible implementation, the functionality of a CU or DU may be partitioned according to traffic type or other system requirements. For example, the processing time may be divided by time delay, and a function that needs to satisfy the time delay requirement may be provided in the DU, and a function that does not need to satisfy the time delay requirement may be provided in the CU. In one possible implementation, a CU may also have one or more functions of a core network device. One or more CUs may be centrally located or separately located. For example, the CUs may be located at network devices to facilitate centralized management. The DU may have multiple rf functions, or may have a remote rf function. The functionality of a CU may be implemented by one entity or by different entities. For example, the functionality of the CU may be further partitioned. For example, a Control Plane (CP) and a User Plane (UP) are separated, i.e., the control plane (CU-CP) of the CU and the user plane (CU-UP) of the CU. For example, CU-CP and CU-UP can be implemented by different functional entities, and CU-CP and CU-UP can be coupled with DUs to collectively perform the functions of a base station. One cell is supported by only one DU. Referring to fig. 12, fig. 12 is a schematic structural diagram of a RAN device with separated CP and UP according to an embodiment of the present invention. As shown in fig. 12, one RAN device may include one CU-CP (i.e., control center), a plurality of CU-UPs, and a plurality of DUs. One DU can only connect to one CU-CP and one CU-UP can only connect to one CU-CP. Under the control of the same CU-CP, one DU can connect a plurality of CU-UP, and one CU-UP can connect a plurality of DU, namely the DU and the CU-UP are in M-to-N relationship. The CU-CP is deployed in a centralized mode, and a plurality of DUs are operated in a coordinated mode; CU-UP distributed deployment, one CU-UP co-deployment with one DU. One UE may connect to multiple CU-UPs simultaneously, and one PDU session corresponds to one CU-UP with a Protocol Data Unit (PDU) session (session) as a granularity. In case that the core network is a 5G core network, the CU-CP may connect an access and mobility management function (AMF) network element through an N2 interface, and the CU-UP may connect a User Plane Function (UPF) network element through an N3 interface. The CU-CP and the CU-UP can be connected through an E1 interface, the CU-CP and the DU can be connected through an F1-C interface, and the DU and the CU-UP can be connected through an F1-U interface.

The core network device may be referred to as CN device, and in the 5G communication system, the core network device may include an UPF network element, an AMF network element, a Session Management Function (SMF) network, a Unified Data Management (UDM) network element, and the like. The UPF network element is responsible for forwarding and receiving user data in the terminal equipment, can receive the user data from the DN and transmits the user data to the terminal equipment through the RAN equipment; user data may also be received from the terminal device by the RAN device and forwarded to the DN. The transmission resource and scheduling function for providing service for the terminal equipment in the UPF network element are managed and controlled by the SMF network element.

In order to better understand a communication method, a communication device, and a computer-readable storage medium disclosed in the embodiments of the present invention, an application scenario of the embodiments of the present invention is described below.

The satellite can be connected with a core network as an independent base station, can also be connected with the ground as a relay base station, can also be connected with a ground CU as a DU, and can also be used as an air work station.

Since GEO satellites are geostationary satellites, both satellites and cells projected to the ground are stationary relative to the ground. When the terminal equipment performs cell selection, reselection or handover in the GEO satellite cell, the process is very similar to the existing terrestrial communication.

LEO satellites are flying around the earth at high speeds, approaching 7 km/s. There are two modes of projection of LEO satellites into the ground in cells:

1. a moving cell (moving cell), i.e., a cell projected to the ground, moves along with a satellite. The antenna of its LEO satellite is always perpendicular to the ground. The LEO, whether acting as a standalone base station or a relay base station, moves with the LEO satellite. Thus, the relative distance between the LEO satellite and the terminal device has been changing and after a period of time the signal of the LEO satellite may not be able to cover the terminal device. In a perfect network deployment, there will be a next LEO satellite to cover the terminal E. Since the satellite system is spherical, the next LEO satellite may come from various angles.

2. Fixed cells (fixed cells), that is, cells projected to the ground are stationary relative to the ground, and an above-ground LEO satellite completes coverage of the same ground position by adjusting an antenna angle, and when the LEO satellite cannot cover the ground position, another LEO satellite takes over the LEO satellite. Referring to fig. 13, fig. 13 is a schematic diagram of a fixed cell according to an embodiment of the present invention. As shown in fig. 13, the LEO satellite completes the coverage of the same position on the ground by adjusting the angle of the antenna.

In the case of MEO and HEO satellites, further description is omitted here.

As can be seen, satellite communications have two features:

1. the ground coverage is easy to have deviation

The cells in satellite communication are all large, and the cell diameter is different from 50kM to 1000 kM. Since the satellite is far from the earth, a slight deviation of the antenna angle or antenna direction of the satellite causes a positional deviation of a cell projected to the ground by several tens kilometers to several hundreds kilometers, so that a cell deviation is caused. Even a little difference in the antenna angle of the satellite can cause the signal coverage of the ground to be different. Particularly, under the condition that the cell of the LEO satellite adopts a fixed cell, the angle of the antenna of the satellite is always changed, so that the cell projected on the ground is ensured to be unchanged, the realization difficulty is high, and errors are easy to occur.

2. Change much

Because many satellites are not relatively static with the ground, that is, the positions between the satellites and the ground are constantly changed, the ground is ensured to have good signal coverage all the time, and networking difficulty is high. For example, in LEO, the flight speed of the satellite is 7km/s, the cell diameter of LEO is about 50km, which means that the time for one satellite in LEO to provide service to the terminal device is only about 7s, and after 7s, the terminal device needs to perform cell reselection or handover to another cell.

Due to the above two characteristics, the network optimization mechanism under satellite communication is much more frequent and complex than that of general terrestrial communication. If the measurement reporting mechanism such as MDT, SON, etc. is still used, it may cause frequent reporting, especially in the LEO mode. Since the time provided to the terminal device in the LEO mode is very short, if a large amount of time-frequency resources are invested for measurement and reporting, the data transmission function of the terminal device itself will be seriously affected. In addition, currently, the measurement and reporting of the terminal device are completely determined by the network device configuration, and the terminal device has no autonomous optimization right.

Referring to fig. 14, fig. 14 is a flowchart illustrating a communication method according to an embodiment of the present invention. Wherein the communication method is described from the perspective of the terminal device, the steps performed by the terminal device below may also be performed by a module (e.g., a chip) in the terminal device. As shown in fig. 14, the communication method may include the following steps.

1401. The filtration conditions are determined.

And under the condition that the terminal equipment needs to carry out measurement and report, the terminal equipment determines the filtering condition. The filtering condition is a condition for not performing measurement and/or reporting, may be a condition for not performing measurement, may also be a condition for not performing reporting, and may also be a condition for not performing measurement and reporting. The measurement is MDT measurement, SON measurement, MDT measurement and SON measurement, and other measurements. The terminal device determines the filtering condition, and may receive the filtering condition from the network device for the terminal device, and the detailed description may refer to the corresponding description in fig. 17, which is not described in detail herein. The filtering condition may also be obtained for the terminal device, and the filtering condition may be generated and stored in advance by the terminal device. Filtering conditions may also be generated for the terminal device.

The terminal device may generate the filter condition according to information that the terminal device can acquire. The information that can be acquired by the terminal device may include one or more of time information, geographical location information, signal strength, capability information of the terminal device, type of the terminal device, and the like. The signal strength may be one or more of RSRP, RSRQ, and signal to interference plus noise ratio (SINR). The capability information of the terminal device may be a capability of accessing the satellite network, a capability of supporting the MDT/SON characteristics, and the like. The types of the terminal equipment can be LTE/NR terminal equipment, Internet of things terminal equipment, Internet of vehicles terminal equipment and the like. The filtering conditions may include one or more of the following: not measuring and/or reporting the specific time or the specific time period; not measuring and/or reporting the specific geographical position; not measuring and/or reporting a specific event; not measuring and/or reporting a specific cell; under the condition that the terminal equipment is in the energy-saving state, the measurement and/or the report are not carried out; under the condition that the terminal equipment is the terminal equipment of the Internet of things, measurement and/or reporting are not carried out; and under the condition that the electric quantity of the terminal equipment is less than or equal to the threshold value, not measuring and/or reporting.

For example, the terminal device may know that HOF, RLF, RACH, RRC establishment failure, RRC recovery failure, etc. must occur in certain geographical locations at a certain time or set of times, according to known information, such as an ephemeris broadcast by the network device, information from the application layer, etc. According to the existing mechanism, the terminal device records the events, and sends an indication that the report exists to the network device after the terminal device enters the connection state, and the network device sends an instruction to enable the terminal device to report. Because the networking in the satellite network is constantly changing, the frequency of the events is much higher than that of the ground network. The more important reason is that during the handover between two satellites, that is, at the moment when the satellite a changes to the area that the satellite B originally covers due to the fact that the satellite a flies into the area that the terminal device cannot cover, the terminal device has a high probability of one or more of HOF, RLF, RACH anew, RRC establishment failure, RRC recovery failure, and the like due to the very fast flight speed of the non-stationary satellite, for example, 7 km/s. Also, because of the fast flight speed of non-geostationary satellites, the connection time of a particular satellite to the terminal device is short, e.g., 15 seconds. Therefore, if the existing mechanism is still used in the NTN, the terminal device will spend a lot of time and signaling to report these events to optimize the network, so as to occupy a lot of time-frequency resources, encroach on the network resources of the satellite communication, and greatly deteriorate the quality of the satellite communication. In addition, as the satellite is very far away, the terminal device reports a large number of reports, which consumes much electric quantity, and wastes the electric quantity of the terminal device. Further, since various events occur repeatedly when two satellites are handed over, the filtering mechanism may also require the network device to process a large number of repeated reports, which is computationally and electrically inefficient. Therefore, the terminal device may use the geographical locations at the times as filtering conditions, so that the terminal device may choose to avoid measurement and reporting of HOF, RLF, RACH, RRC establishment failure, RRC recovery failure, and the like at the geographical locations at the times when performing measurement. The time may be a relative time, such as after five minutes, or an absolute time, such as coordinated Universal Time (UTC). The geographic location may be a relative location, such as a distance and a direction from a reference location, or an absolute location, such as latitude and longitude information.

For another example, as can be seen from the above description, in the above process, the terminal device has a high probability of generating one or more of an HOF, an RLF, a RACH anew, an RRC establishment failure, an RRC recovery failure, and the like, and therefore, these events may be determined as filtering conditions, so that the terminal device does not measure and/or report these events, thereby reducing occupation of a large amount of time-frequency resources, and simultaneously saving the power of the terminal device, thereby improving the service quality of the terminal device communication. In addition, because various events can repeatedly occur when the two satellites are handed over, the filtering mechanism can also enable the network equipment not to process a large number of repeated reports, so that the resources and the electric quantity of the network equipment can be saved, and the communication service quality of the network equipment can be improved.

For another example, since the network device does not completely know the state of the terminal device, such as the power level, the network device may cause great damage to the terminal device when the network device selects the terminal device to measure and report. For example, it may result in the terminal device not having enough power to support normal data transmission traffic. In order to solve the above problem, the terminal device may determine, as the filtering condition, one or more of that the terminal device is in an energy saving state, that the terminal device is an internet of things terminal device, that an electric quantity of the terminal device is less than or equal to a threshold value, and the like. With these filtering conditions, some terminal devices that are not well suited for reporting can preferentially perform more important services, such as data transmission, conversation, etc., without performing measurement and/or reporting. The internet of things terminal device may be a narrowband base internet of things (NB-IoT) terminal device, and may also be an enhanced machine communication (eMTC) terminal device.

For another example, when the measurement object is a cell such as a satellite projection cell, the cell may cause the terminal device to generate an HOF, an RLF, an RACH, an RRC establishment failure, an RRC recovery failure, and the like due to movement of a satellite, and therefore, the measurement object may be determined as a specific cell as a filtering condition, so that when the terminal device is in the cell, measurement and/or reporting are not required, thereby reducing occupation of a large amount of time-frequency resources, and saving power of the terminal device, thereby improving service quality of communication of the terminal device.

1402. Measurements were made according to the filtration conditions.

After the terminal device determines the filtering condition, the measurement may be performed according to the filtering condition, such as MDT measurement, SON measurement, and the like. It can be determined which information needs to be measured and which information does not need to be measured according to the filtering condition, and then the information needing to be measured is measured.

1403. And reporting the measurement result to the network equipment according to the filtering condition.

After the terminal device performs measurement according to the filtering condition, that is, after the terminal device finishes measurement according to the filtering condition, the terminal device may report the measurement result to the network device according to the filtering condition. The information needing to be reported and the information not needing to be reported can be determined according to the filtering condition, and then the information needing to be reported is reported.

For example, the cell of the frequency point corresponding to the cell where the terminal device in the RRC idle state or the RRC deactivated state currently resides and the cell broadcasted in the cell currently resides are reselected to correspond to the inter-frequency/inter-system neighboring cell to perform measurement. When the terminal device is in the RRC connected state, the network device configures the configuration information related to the logged MDT for the terminal device. After the terminal device receives the configuration information from the network device, when the terminal device enters RRC _ IDLE or RRC _ INACTIVE, the terminal device performs measurement according to the configuration information, and buffers the measurement result in the terminal device. After the terminal device enters RRC _ CONNECTED, the terminal device may indicate whether there is a logged MDT measurement result in a message such as RRC setup/resume/reestablishment Complete (RRC setup/resume/re-establishment Complete). After receiving the indication Information with the logged MDT measurement result from the terminal device, the network device may issue a User Equipment (UE) Information Request (UE Information Request) message to the terminal device. After receiving the UE Information Rrequest message from the network device, the terminal device may report the logged MDT measurement result to the network device through a UE Information Response (UE Information Response) message. The configuration information configured by the network device may include a filtering condition, and after receiving the configuration information, the terminal device may perform measurement and/or report according to the filtering condition. After receiving the configuration information from the network device, the terminal device may generate a filtering condition or obtain a stored filtering condition, then determine information that needs to be measured and/or reported according to the filtering condition and the configuration information, and then execute the following related steps.

For example, the L2 measurements may include radio link measurements, which may include RLF reports (reports). The RLF report may include RLF, HOF, and the like. After the terminal device fails to RLF, HOF, etc., the terminal device may record the RLF, HOF, etc., so that the terminal device may indicate whether there is RLF information (RLF Info) in an RRC re-establishment Complete (RRC re-establishment Complete) message after entering an RRC connected state. After receiving the indication Information with the RLF Info from the terminal device, the network device may issue a UE Information Request message to the terminal device. After receiving the UE Information Rrequest message from the network device, the terminal device may report the RLF report to the network device through the UE Information Response message. The L2 measurements may also include access measurements (access measures), which may include RRC connection setup failure (RRC connection setup failure), RRC recovery failure (RRC resume failure), and so on. The terminal device may report measurements such as radio link measurements, access measurements, etc. according to the filtering conditions.

ANR can be implemented by a terminal device, and is a function that a base station needs to know the situation of neighboring cells in order to make various decisions such as measurement and handover. In brief, each base station maintains a neighbor cell relation table for a cell, and adds or deletes neighbor cells in the neighbor cell relation table according to various measurement results reported by the terminal device. Referring to fig. 15, fig. 15 is a schematic flowchart illustrating an ANR establishing a neighboring relation according to an embodiment of the present invention. As shown in fig. 15, the ANR establishing a neighbor relation may include the following steps.

1. The terminal device may report a measurement report containing the measured PCI of the target cell to the base station of cell a. For example, the cell a may be a serving cell of the terminal device, and the base station may be a serving base station of the terminal device. For example, PCI 5 may represent a target cell, which is a local identity and has no network-wide uniqueness.

2. When the base station determines that there is no PCI of the target cell in the neighboring cell relationship table of the cell a, or the base station determines that the PCI at the corresponding frequency point appears for the first time, or the base station determines that the PCI is unknown, the base station may send a Cell Global Identifier (CGI) request message to the terminal device. The CGI request message may contain the PCI of the target cell. The CGI request message is used to instruct the terminal device to read the CGI of the target cell and report the CGI of the target cell to the base station.

3. And the terminal equipment reads the CGI of the target cell. After receiving the CGI request message from the base station, the terminal device may read the CGI of the target cell according to the CGI request message. For example, the terminal device may obtain the CGI of the target cell by reading a System Information Block (SIB) 1 broadcasted by the target cell. Optionally, the CGI may include an Evolved Cell Global Identifier (ECGI) or a new radio access technology cell global identifier (NRcell global identifier, NCGI).

4. And the terminal equipment reports the CGI of the target cell to the base station. For example, the terminal device may send the CGI of the target cell to the base station through a measurement report.

5. And the base station adds the target cell to a neighbor relation table of the cell A. After receiving the CGI of the target cell from the terminal device, the base station determines that the target cell may be the pilot cell of the cell a, and then may add the target cell to the neighboring cell relation table of the cell a.

The CGI request message in step 2 may include or carry a filtering condition, and once the terminal device meets the filtering condition, the terminal device will not read the CGI of the target cell and/or report to read the CGI of the target cell, that is, step 3-step 5 or step 4-step 5 does not occur.

Referring to fig. 16, fig. 16 is a flowchart illustrating another communication method according to an embodiment of the disclosure. The steps performed by the following terminal device may also be performed by a module (e.g., a chip) in the terminal device, and the steps performed by the following network device may also be performed by a module (e.g., a chip) in the network device. As shown in fig. 16, the communication method may include the following steps.

1601. The network device determines the filtering condition of the terminal device.

The network device may determine a filtering condition for the terminal device. The network device may determine filtering conditions for one or more terminal devices. The filter conditions determined for different terminal devices may be the same or different. In a case where the network device stores the filtering condition of the terminal device, the network device determines the filtering condition of the terminal device, and may acquire the stored filtering condition of the terminal device for the network device, where the filtering condition may be generated and stored in advance by the network device. In the case that the network device does not store the filtering condition of the terminal device, the network device determines the filtering condition of the terminal device, and may generate the filtering condition for the network device. The filtering conditions may be determined by the base station. The filtering condition may also be determined by the core network device, for example, by an AMF network element, and then the core network device may send the filtering condition to the base station through a Non Access Stratum (NAS) message.

The network device may generate the filtering condition of the terminal device according to the information that the terminal device can acquire. The information that can be acquired by the terminal device may include one or more of time information, geographical location information, signal strength, capability information of the terminal device, type of the terminal device, and the like. The signal strength may be a signal strength of one or more of RSRP, RSRQ, and signal to interference plus noise ratio, SINR. The capability information of the terminal device may be a capability of accessing the satellite network, a capability of supporting the MDT/SON characteristics, and the like. The types of the terminal equipment can be LTE/NR terminal equipment, Internet of things terminal equipment, Internet of vehicles terminal equipment and the like. The filtering conditions may include one or more of the following: not measuring and/or reporting the specific time or the specific time period; not measuring and/or reporting the specific geographical position; not measuring and/or reporting a specific event; not measuring and/or reporting a specific cell; under the condition that the terminal equipment is in the energy-saving state, the measurement and/or the report are not carried out; under the condition that the terminal equipment is the terminal equipment of the Internet of things, measurement and/or reporting are not carried out; and under the condition that the electric quantity of the terminal equipment is less than or equal to the threshold value, not measuring and/or reporting.

For the detailed description of different filtering conditions in the filtering conditions, reference may be made to the above description, which is not repeated herein.

1602. The network device sends the filter condition to the terminal device.

After determining the filtering condition of the terminal device, the network device may send the filtering condition to the terminal device. The network device may send a NAS message carrying the filter condition to the terminal device. The network device may send the filter condition, such as an RRC message, to the terminal device using dedicated signaling. The network device may also broadcast the filter criteria to the end devices via system broadcasts. The network device may also send the filter criteria to the end devices via dedicated signaling and system broadcasts. In one case, whether the dedicated signaling is subject to the system broadcast or the dedicated signaling is subject to the system broadcast may be determined according to the priority of the dedicated signaling and the system broadcast. For example, in a case where the priority of the dedicated signaling is higher than the priority of the system broadcast, the terminal device receives the filtering condition of the system broadcast first and then receives the filtering condition transmitted through the dedicated signaling, and the terminal device may control the filtering condition of the received dedicated signaling transmission. In another case, whether the dedicated signaling is based on the system broadcast or the dedicated signaling is based on the system broadcast may be determined according to the sequence of the received dedicated signaling and the system broadcast, with the first received being based on the system broadcast. In yet another case, it may be decided by both dedicated signaling and system broadcast. For example, the system broadcast transmits a part of common filtering conditions, the dedicated signaling transmits different filtering conditions for each terminal device, and the terminal devices can combine the filtering conditions after receiving the system broadcast and the dedicated signaling to obtain complete filtering conditions. The network device may send the filter conditions separately to the terminal device. The network device may also generate configuration information including the filter condition and send the configuration information to the terminal device. The process of sending the configuration information is similar to the process of sending the filter condition described above. The configuration information may also include indication information for measurement and reporting.

Accordingly, the terminal device receives the filter condition from the network device.

1603. And the terminal equipment performs measurement according to the filtering condition.

Step 1603 is the same as step 1402, and please refer to step 1402 for detailed description, which is not described herein again.

1604. And the terminal equipment reports the measurement result to the network equipment according to the filtering condition.

Step 1604 is the same as step 1403, and please refer to step 1403 for detailed description, which is not described herein again. In addition, after receiving the measurement result reported from the terminal device, the network device may process the measurement result.

Referring to fig. 17, fig. 17 is a flowchart illustrating another communication method according to an embodiment of the present invention. The steps performed by the following terminal device may also be performed by a module (e.g., a chip) in the terminal device, and the steps performed by the following network device may also be performed by a module (e.g., a chip) in the network device. As shown in fig. 17, the communication method may include the following steps.

1701. The network device sends the configuration information to the terminal device.

When the network device needs to perform measurement and report, the network device may generate configuration information, where the configuration information may include indication information for performing measurement and report. The network device may then send the configuration information to the terminal device. The network device may send a NAS message carrying the configuration information to the terminal device. The network device may use dedicated signaling to send configuration information, such as RRC messages, to the terminal device. The network device may also broadcast the configuration information to the terminal devices via system broadcasts. The network device may also send configuration information to the terminal device via dedicated signaling and system broadcasts. In one case, whether the dedicated signaling is subject to the system broadcast or the dedicated signaling is subject to the system broadcast may be determined according to the priority of the dedicated signaling and the system broadcast. For example, when the priority of the dedicated signaling is higher than that of the system broadcast, the terminal device receives the configuration information of the system broadcast first and then receives the configuration information transmitted through the dedicated signaling, and the terminal device may control the received configuration information transmitted through the dedicated signaling. In another case, whether the dedicated signaling is based on the system broadcast or the dedicated signaling is based on the system broadcast may be determined according to the sequence of the received dedicated signaling and the system broadcast, with the first received being based on the system broadcast. In yet another case, it may be decided by both dedicated signaling and system broadcast. For example, the system broadcast sends a part of common configuration (cell specific), the dedicated signaling sends a different configuration (UE specific) for each terminal device, and the terminal devices receive the system broadcast and the dedicated signaling and then can combine them to obtain complete configuration information.

1702. The terminal device determines the filtering condition.

After the terminal device receives the configuration information from the network device, the filtering condition may be determined, and the filtering condition may be determined according to the configuration information. In the case that the terminal device stores the filtering condition, the terminal device determines the filtering condition, which may be the stored filtering condition, and the filtering condition may be generated and stored in advance by the terminal device. In the case where the terminal device does not store the filtering condition, the terminal device determines the filtering condition, which may be generation of the filtering condition.

The terminal device may generate the filter condition according to information that the terminal device can acquire. The detailed description may refer to step 1401, which is not described herein.

1703. And the terminal equipment performs measurement according to the filtering condition.

Step 1703 is the same as step 1402, and please refer to step 1402 for detailed description, which is not described herein again.

1704. And the terminal equipment sends the measurement result to the network equipment according to the filtering condition.

Step 1704 is the same as step 1604, and please refer to step 1604 for detailed description, which is not repeated herein.
