With the foregoing drawings in mind, certain embodiments of the disclosure have been shown and described in more detail below. These drawings and written description are not intended to limit the scope of the disclosed concepts in any way, but rather to illustrate the concepts of the disclosure to those skilled in the art by reference to specific embodiments.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Referring to fig. 1, fig. 1 is a diagram of a network topology related to a single anchor point scheme in the prior art. The single anchor point scheme refers to: one network operator establishes the anchor base station and the 5G base station as an adopter, so that a user equipment UE, which is attributed to another network operator (sharing party), can use the shared network of the anchor base station and the 5G base station, and the UE can also use the shared network of the base station established by the sharing party. The line, complement, power system of the anchor base station can be used by the 5G base station, and the anchor base station transmits the received signaling to the 5G base station, so that the 5G base station processes the signaling.

Fig. 1 includes an underwriter EPC (Evolved Packet Core, EPC for short, 4G Core network) and a shared EPC, where the underwriter EPC is connected to a 4G unshared base station, a 4G shared base station (anchor base station) and a 5G shared base station of the underwriter through a link S1-U, the underwriter EPC is connected to a 4G unshared base station and a 4G shared base station (anchor base station) of the underwriter through a link S1-C, the shared EPC is connected to a 4G shared base station (anchor base station), a 5G shared base station and a 4G unshared base station of the shared party through a link S1-U, and the shared EPC is connected to a 4G unshared base station of the shared party and a 4G shared base station (anchor base station) of the underwriter through a link S1-C. And the contractor EPC and the sharer EPC perform data interaction with the connected base stations through links. The anchor base station and the 5G base station perform data transmission through a link EN-DC (EUTRA-NR Dual Connection, EN-DC for short) X2.

A shared cell (the shared cell is an area covered by signal radiation of the anchor base station and is not marked) broadcasts a PLMN (Public Land Mobile Network, PLMN for short) of the anchor base station, where a frequency point of the PLMN is L1800(1.8GHz), that is, the anchor base station shares the PLMN with the frequency point of L1800(1.8 GHz). The shared cell may also broadcast the PLMN of the 5G base station, where the frequency point of the PLMN is 3.5GNR, that is, the PLMN with the frequency point of 3.5GNR is shared by the 5G base station. PLMN1 in fig. 1 is the PLMN of the base station established by the contractor of the shared cell broadcast. In addition, the address of the shared cell is shared by two network operators, so the shared cell can also broadcast the PLMN2 of the base station established by the sharing party. As shown in fig. 1, both the non-persistent one (NSA) UE (5G UE) of the contractor and the NSA UE of the sharing party may connect to the PLMN1 and the PLMN2 in the sharing cell. And the contractor 4G UE located outside the shared cell is connected to the PLMN1, and the sharer 4G UE located outside the shared cell is connected to the PLMN 1.

Referring to fig. 2, when an NSA UE of a sharing party moves to a boundary of a sharing cell and the NSA UE moves toward a 4G unshared base station of the sharing party, the NSA UE of the sharing party switches a PLMN1 of an anchor base station connected to a PLMN2 of the sharing party by an inter-frequency switching manner. In order to ensure that the NSA UE of the sharing party can occupy the 5G network as much as possible, the first pilot frequency switching threshold a2 of the anchor base station in the shared cell is set to-109 dBm, and the second pilot frequency switching threshold a4 of the sharing base station of the sharing party in the shared cell is set to-105 dBm. Because the shared cell broadcasts the shared PLMN1-1 with the frequency point of the anchor base station being L1800, and the border of the shared cell has the non-sharable PLMN1-2 with the frequency point of L1800 radiated by the 4G non-shared base station of the construction party, the NSA UE of the sharing party is switched from the accessed PLMN1-1 to the PLMN of the shared base station of the sharing party, and the same frequency interference exists. In addition, A2 is-109 dBm, and A2 is set too low, so that the UE has the problems of poor handover quality, reconstruction and even handover failure after the network is switched. Through tests, in the process of switching the network by the sharing party NSA UE, the network quality SINR (Signal to Interference plus Noise Ratio, SINR for short) is below 0, and if the SINR is lower than-10 dB under the condition of dense base stations, it is seen that the network quality after switching the network is poor, which affects the user perception.

The following describes the technical solutions of the present invention and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.

Referring to fig. 3, fig. 3 is a network sharing system provided by the present invention.

The network sharing system includes a 5G base station 100, a first 4G base station 200, a second 4G base station 300, and a third 4G base station 400. The 5G base station 100 is a shared base station established by a contractor; the first 4G base station 200 is a shared base station established by the contractor, and the first 4G base station 200 is an anchor base station; the second 4G base station 300 is a shared base station or an unshared base station established by the sharing party; and a third 4G base station 400 located in an area 500 covered by the signals of the first 4G base station 200 and the second 4G base station 300, and a shared base station established by a third 4G base station contractor.

Shared base stations means that the PLMN of the cell broadcast base station can be used by users of other home locations. For example, the cell broadcasts the PLMN1 of the base station established by the a network operator, and the UE belonging to the B network operator may connect to the PLMN1 in the cell to surf the internet. The PLMN2 of the unshared base station can be connected and used only by UEs belonging to the network operator of the unshared base station. For example, the unshared base stations are established by the a network operator, only UEs homed to the a network operator can connect to and use the PLMN2 of the unshared base stations, and UEs homed to the B network operator cannot connect to and use the PLMN 2. It should be noted that the arrows in fig. 3 indicate the direction of signal transmission from the base station.

Referring to fig. 4, since the third 4G base station 400 is located between the first 4G base station 200 and the second 4G base station 300, and the third 4G base station 400 is a shared base station established by the contractor, the third 4G base station 400 can shield signals of the fourth 4G base station 600 (the fourth 4G base station 600 is a non-shared base station established by the contractor), that is, the third 4G base station 400 can be used as a buffer zone of the UE handover network. When the sharing party 5G UE is at the boundary of the shared cell (the boundary is the area radiated by the first 4G base station and the second 4G base station), the third 4G base station 400 can shield the co-channel interference of the fourth 4G base station 500 to the sharing party 5G UE.

Through test verification, after the third 4G base station is arranged in the area 500 covered by the first 4G base station 200 and the second 4G base station 300, the network quality SINR of the 5G UE during the shared cell handover is improved by more than 10dB, and the user perception is effectively improved.

In this embodiment, the third 4G base station is used as the shared base station of the construction party and is located in the area covered by the first 4G base station and the second 4G base station, so that the third 4G base station can shield the co-frequency interference of the non-shared base station of the construction party to the UE, and the network quality after the UE switches the network is improved.

Further, referring to fig. 5, the third 4G base station 400 is plural, and each of the third 4G base stations is disposed around the first 4G base station 100 such that each of the third 4G base stations 600 forms a buffer zone for network handover of the 5G UE. The boundary of the 5G UE at any position in the shared cell is relatively weak to the co-channel interference of the unshared base station of the construction party. The boundary of the shared cell is a zone of the 5G UE switching network, and each third 4G base station can be arranged at the boundary of the shared cell, so that the co-frequency interference of the non-shared base station of the construction party on the shared cell of the 5UG UE is reduced to the maximum extent.

Further, after the third 4G base station is set between the first 4G base station 200 and the second 4G base station 300, the first inter-frequency handover threshold a2 of the first 4G base station signal in the shared cell is set to-45 dBm to-55 dBm, that is, the first inter-frequency handover threshold a2 of the shared cell is set to-45 dBm to-55 dBm. The A2 in the invention is larger than the A2 in the prior art (A2 in the prior art is-109 dBm), so that the 5G UE can perform pilot frequency measurement under the condition of better signal quality, and the success rate of network switching is improved. It should be noted that when the UE detects that the RSRP (Reference Signal Receiving Power, RSRP for short) of the serving cell is less than a2, the UE starts to detect the RSRP of the inter-frequency neighboring cell.

In addition, when the 5G UE measures the pilot frequency point, the system resources of the network sharing system are greatly occupied, and the uploading rate and the downloading rate of data are affected. Therefore, the measurement of the pilot frequency needs to be started as short as possible before the 5G UE performs the pilot frequency handover, so as to reduce the consumption of the system resources by the audio measurement. In contrast, the second pilot frequency handover threshold a4 of the second 4G base station signal in the shared cell is set to-115 dBm to-125 dBm, and the 5G UE starts to perform pilot frequency handover again.

The second pilot switching threshold a4 is a Reference Signal Receiving Power (RSRP) threshold of the pilot neighboring cell where the UE starts to switch to the pilot neighboring cell. The closer the 5G UE is to the boundary of the shared cell, the larger the RSRP of the pilot frequency adjacent cell is, but A4 in the invention is smaller than A4 in the prior art (A4 in the prior art is-105 dBm), compared with the prior art, the 5G UE can switch the pilot frequency adjacent cell at the position where the RSRP of the pilot frequency adjacent cell is smaller, thereby shortening the measurement time before the UE pilot frequency switching.

Referring to fig. 6, fig. 6 is a first embodiment of a network switching method according to the present invention, where the network switching method includes:

step S10, obtain a first reference signal received power, RSRP, of the first 4G base station in the cell where the UE is located, where a first network to which the UE currently accesses is provided by the first 4G base station.

In this embodiment, the execution subject is user equipment UE. The UE is connected with a 4G network provided by a first 4G base station in a network sharing system, the 4G network is defined as a first network, the UE is a 5G device, and the home of the UE is a sharing party.

The network sharing system includes a 5G base station 100, a first 4G base station 200, a second 4G base station 300, and a third 4G base station 400. The 5G base station 100 is a shared base station established by a contractor; the first 4G base station 200 is a shared base station established by the contractor, and the first 4G base station 200 is an anchor base station; the second 4G base station 300 is a shared base station or an unshared base station established by the sharing party; and a third 4G base station 400 located in an area 500 covered by the signals of the first 4G base station 200 and the second 4G base station 300, and a shared base station established by a third 4G base station contractor.

Shared base stations means that the PLMN of the cell broadcast base station can be used by users of other home locations. For example, the cell broadcasts the PLMN1 of the base station established by the a network operator, and the UE belonging to the B network operator may connect to the PLMN1 in the cell to surf the internet. The PLMN2 of the unshared base station can be connected and used only by UEs belonging to the network operator of the unshared base station. For example, the unshared base stations are established by the a network operator, only UEs homed to the a network operator can connect to and use the PLMN2 of the unshared base stations, and UEs homed to the B network operator cannot connect to and use the PLMN 2. It should be noted that the arrows in fig. 3 indicate the direction of signal transmission from the base station.

Referring to fig. 4, since the third 4G base station 400 is located between the first 4G base station 200 and the second 4G base station 300, and the third 4G base station 400 is a shared base station established by the contractor, the third 4G base station 400 can shield signals of the fourth 4G base station 600 (the fourth 4G base station 600 is a non-shared base station established by the contractor), that is, the third 4G base station 400 can be used as a buffer zone of the UE handover network. When the sharing party 5G UE is at the boundary of the shared cell (the boundary is the area radiated by the first 4G base station and the second 4G base station), the third 4G base station 400 can shield the co-channel interference of the fourth 4G base station 500 to the sharing party 5G UE.

When the UE is in a cell (a cell of a PLMN broadcasting the first 4G base station), the UE detects a reference signal received power of the first 4G base station in the cell, where the detected reference signal received power is defined as a first RSRP. The UE compares the detected first RSRP with a first inter-frequency handover threshold a2 of the first 4G base station to determine whether the first RSRP is smaller than a 2.

Step S20, when the first RSRP is smaller than the first inter-frequency handover threshold a2 of the first 4G base station, obtain a second RSRP of the second 4G base station in the cell.

When the first RSRP is less than the first pilot frequency handover threshold a2, the UE starts pilot frequency measurement, so as to detect the reference signal received power of the second 4G base station in the shared cell, where the reference signal received power is defined as the second RSRP. The UE further compares the second RSRP with A4 of the second 4G base station to determine whether the second RSRP is greater than or equal to A4.

Step S30, when the second RSRP is greater than or equal to the second inter-frequency handover threshold a4 of the second 4G base station, the first network accessed by the UE is switched to the second network provided by the second 4G base station.

When the second RSRP is greater than or equal to the second inter-frequency handover threshold a4, the UE switches the accessed first network to the second network provided by the second 4G base station.

It should be noted that, the third 4G base station is located between the first 4G base station and the second 4G base station, and when the UE performs inter-frequency handover (network handover), the third 4G base station may shield co-frequency interference of the unshared base station of the infrastructure party to the UE, so that even if a2 is set to-109 dBm and a4 is set to-105 dBm, the network quality after the UE switches the network can be improved.

Through measurement, by using the network sharing system provided by the embodiment, a2 can be set to-45 dBm-55dBm, that is, a2 is greater than or equal to-45 dBm, and a2 is less than or equal to-55 dBm; the 5G UE can perform pilot frequency measurement under the condition of better signal quality, and the success rate of UE network switching can be improved. In addition, A4 was set to-115 dBm-125dBm, i.e., A4 was less than or equal to-115 dBm and A4 was greater than or equal to-125 dBm. Therefore, the measurement time before UE pilot frequency switching can be greatly shortened, and the data uploading rate and the downloading rate of the network sharing system are provided.

In the technical solution provided in this embodiment, the UE obtains a first reference signal received power RSPR of the first 4G base station in the shared cell, and performs inter-frequency measurement when the first RSRP is smaller than a2, that is, obtains a second RSRP of the second 4G base station in the shared cell; and if the second RSRP is greater than or equal to A4, switching the network accessed by the UE to the network provided by the second 4G base station. And the third 4G base station is located in the area covered by the first 4G base station and the second 4G base station, so that the third 4G base station shields the co-frequency interference of the non-shared base station of the construction party to the UE, and the network quality after the UE switches the network is improved.

In one embodiment, step S10 includes:

and acquiring the position of the UE.

And when the position is in the area, acquiring first Reference Signal Received Power (RSRP) of a cell where the UE is located of the first 4G base station.

In this embodiment, the UE may obtain the location of the UE through the positioning module. The third 4G base station is located in an area set to the coverage of the signal transmitted by the first 4G base station and the signal transmitted by the second 4G base station, that is, the area is the area of the UE handover network. In contrast, after the UE obtains the position of the UE, whether the position is in the area or not is determined, if the position is in the area, the UE obtains the first RSRP of the first 4G base station in the cell, the UE does not need to detect the first RSRP in real time, and therefore computing resources of the UE are saved.

In one embodiment, the status of the 5G base station includes an idle status and a busy status. The busy state refers to that the 5G base station has traffic data to process, and the busy state can be defined as a traffic state. And the idle state refers to that the 5G base station has no service data processing, and can be defined as the idle state. When the UE needs to switch the accessed network to the network provided by the second 4G base station, the UE firstly determines the state of the 5G base station, and the state can be fed back to the UE by the 5G base station. If the state of the 5G base station is a busy state, switching the network by adopting a switching scheme of A2+ A4; and if the 5G base station is in an idle state, performing frequency point switching (the frequency point switching is network switching) in a priority mode.

Specifically, the UE acquires the location of the UE, and the current acquired location and the last acquired location are used to determine the moving direction of the UE. If the moving direction is that the UE is far from the shared cell, that is, the UE moves toward the area, the UE transmits a request for acquiring the state to the 5G base station, so as to receive the state of the 5G base station fed back by the 5G base station. And if the state of the 5G base station is a busy state, acquiring first Reference Signal Received Power (RSRP) of a first 4G base station in a cell, and performing network switching by adopting an A2+ A4 scheme. And if the state of the 5G base station is an idle state, the UE acquires a frequency point priority switching list of the currently used public land mobile network PLMN, and then switches the frequency point accessed by the UE to the frequency point with the highest priority in the frequency point priority switching list so as to switch the network corresponding to the frequency point with the highest priority of the first network accessed by the UE. The priority of each frequency point in the priority switching list is preset.

In this embodiment, the UE may flexibly perform network handover based on the state of the 5G base station.
