Detailed Description

The present disclosure now will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the disclosure are shown. The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

The terms "first", "second", and the like are used hereinafter only for descriptive distinction and not for other specific meanings.

Fig. 1 is a flowchart illustrating a terminal access control method according to an embodiment of the present disclosure, as shown in fig. 1:

step 101, a mobility Management entity mme (mobility Management entity) of a first operator network acquires terminal capability information reported by a terminal belonging to the first operator network; the terminal is located in a network sharing area of a first operator network and a second operator network.

The first operator may be china telecom, etc., and the second operator may be china unicom, etc. The first operator network and the second operator network both cover the network sharing area, and the first operator network can be a 4G network. The base station comprises a 4G base station and the like, and the terminal is a mobile phone, a tablet personal computer and the like.

Step 102, if the MME judges that the terminal supports the 5G mode based on the terminal capability information, the MME sends a frequency priority policy to a base station of the first operator network to which the terminal is currently attached. There may be a plurality of frequency priority policies, and the frequency priority policy includes a frequency point number corresponding to a base station of the second operator network, which is preferentially used by the terminal, and the like.

103, the base station controls the terminal to attach to a second operator network based on the frequency priority policy, wherein the second operator network comprises: a 5G network of a second operator covering the network sharing area. The networking mode of the second operator network comprises: and a non Stand-Alone network NSA (non Stand-Alone), wherein the base station controls the terminal to access to a 5G base station in a second operator network and the like based on the frequency priority strategy.

For a network sharing area of a first operator network and a second operator network, both the first operator network and the second operator network cover the network sharing area, the first operator network may be a 4G network, and the second operator network includes: the NSA of the second operator covering the network sharing area shares the network. The second operator network is a 4G network, and a 5G anchor point is added in the network sharing area to form 5G network coverage for networking in a networking mode of NSA. The NSA shared network of the second operator is a 5G network of the second operator network that is networked in a networking mode of NSA, and the terminal belonging to the first operator network can access the NSA base station of the NSA shared network.

In a scenario where a 5G network, in which a second operator performs networking in a networking mode of NSA, is shared with a first operator network, for a terminal a (a terminal of a user of the first operator) belonging to the first operator network, the priority of the 5G network of the second operator network is not higher than that of the first operator network (a 4G network), and the priorities are generally the same, the terminal a is not actively attached to the 5G network of the second operator network. And upgrading the function of the MME of the first operator network, identifying the capability of the accessed terminal, and guiding the terminal to select the NSA network as soon as possible when the terminal is found to have the capability of supporting the NSA network (the 5G network which is networked in the networking mode of the NSA).

The terminal of the 5G user belonging to the first operator network is started in a network sharing area of the first operator network and the second operator network, or the terminal is moved to the network sharing area from the local network area of the first operator network, the MME judges whether the terminal supports 5G or not through an attach request or a registration message, if so, a specific frequency priority strategy is issued to a base station (4G base station); and the base station issues the frequency priority strategy to a user, and the user reselects to the NSA network of a second operator covering the network sharing area according to the frequency priority strategy. The frequency priority policy includes a frequency point number and the like preferentially used by the terminal and corresponding to a base station of the second operator network, and the terminal accesses the NSA base station of the second operator based on the frequency point.

The MME does not need to determine whether the access area of the terminal is the network sharing area, and only the base station of the first operator network located in the network sharing area configures the specific frequency priority policy, and in the non-network sharing area, the base station of the first operator network does not identify the policy, so that the specific frequency priority policy is not executed.

In one embodiment, there may be multiple methods for the MME to obtain the terminal capability information reported by the terminal belonging to the first operator network. Fig. 2 is a schematic flowchart of a process of acquiring terminal capability information in an embodiment of a terminal access control method according to the present disclosure, as shown in fig. 2:

in step 201, the MME receives a location registration request message or an attach request initiated by the terminal. The location registration request message and the attach request may be an existing location registration request message or an attach request.

Step 202, the MME acquires the terminal Capability information of the terminal according to the information carried in the Capability field in the location registration request message or the attach request.

The Capability field may be obtained from the location registration request message or the attach request by using an existing method, and the terminal Capability information of the terminal may be obtained based on the information carried in the Capability field.

When a terminal is started in a network sharing area, sending an attach request; when the terminal moves to the network shared area, a location registration request message is transmitted. And the base station issues the frequency priority strategy to the terminal so that the terminal reselects to the second operator network according to the frequency priority strategy. The frequency priority policy includes: RFSP (RAT/Frequency selection priority) parameter; the RFSP parameter may be an RFSP Index or the like, and the RFSP parameter and the RFSP Index may be an existing RFSP parameter and an RFSP Index.

If the base station is located in the network sharing area, a strategy corresponding to the SPID value is configured in the base station in advance; if the base station is not located in the network sharing area, the strategy corresponding to the SPID value is not configured in advance in the base station, and the strategy can be a frequency priority issuing strategy and the like. The base station obtains a corresponding SPID (subscriber profile ID) value based on the RFSP parameter; and the base station judges whether a strategy corresponding to the SPID value is configured locally or not, and if so, the frequency priority strategy is sent to the terminal. The frequency priority strategy received by the terminal comprises a frequency point number which is preferentially used by the terminal and corresponds to the base station of the second operator network, and the terminal accesses the NSA base station of the second operator network based on the frequency point number.

In one embodiment, the MME distinguishes between 4G and 5G users or terminals, issues a specific frequency policy (RFSP) to a base station for a target user, the base station maps an RFSP parameter to an SPID, if the base station configures a policy corresponding to the SPID, executes the policy for the user, and forces the user to be redirected to a shared network, and only the base station in a network sharing area configures the SPID corresponding to the specific RFSP parameter, thereby ensuring that the redirection policy is implemented for the user only in the network sharing area.

For the scenario that the terminal is powered on in the network sharing area, as shown in fig. 3, the signaling interaction flow is as shown in fig. 5: the network A is a first operator network, and the network B is a second operator network. In a network sharing area, a first operator and a second operator both have 4G coverage, and a 4G base station added into the second operator is upgraded into a 5G anchor station; the MME of the first operator needs to issue a policy to the base station of the first operator, and guides the NSA terminal user of the first operator to be switched to the NSA base station of the second operator.

The method comprises the steps that a 5G terminal of a first operator is started in a network sharing area of the first operator and a second operator, an MME of the first operator network judges whether the terminal supports 5G or not through a UE Capability field in an attach request, and if yes, a specific frequency priority strategy RFSP parameter is issued to a base station of the first operator network. The base station maps the RFSP parameter to the SPID, if the base station is configured with the strategy corresponding to the SPID, the frequency priority strategy is issued to the user to guide the user to reselect to the NSA base station in the 5G network (networking is carried out in the NSA mode) covering the network sharing area of the second operator. The MME does not determine whether the access area of the user is the network sharing area, but only the base station of the first operator network in the network sharing area configures the specific frequency priority policy SPID, and in the non-network sharing area, the base station of the first operator network does not recognize the RFSP, and thus is not executed.

For a scenario in which a terminal moves from a home network to a network sharing area, as shown in fig. 4, a signaling interaction flow is shown in fig. 5: the network A is a first operator network, and the network B is a second operator network. And the 5G terminal of the first operator moves to a network sharing area of the first operator and the second operator in the power-on state. And the MME judges whether the terminal supports 5G or not through a UECapacity field in a position registration request message initiated by the terminal, and if so, sends a specific frequency priority strategy RFSP parameter to a base station of the first operator network. The base station maps the RFSP parameter to the SPID, if the base station of the first operator network is configured with the strategy corresponding to the SPID, the frequency priority strategy is issued to the user, and the user is guided to reselect to the NSA base station in the 5G network (networking in the NSA mode) covering the network sharing area of the second operator. The MME does not determine whether the access area of the user is the network sharing area, but only the base station of the first operator network in the network sharing area configures the specific frequency priority policy SPID, and in the non-sharing area, the base station of the first operator network does not recognize the RFSP, and thus is not executed.

In one embodiment, the present disclosure provides an MME device 60, applied to a first operator network, including: a terminal capability obtaining module 61 and a priority issuing module 62. The terminal capability obtaining module 61 obtains terminal capability information reported by a terminal belonging to a first operator network; the terminal is located in a network sharing area of a first operator network and a second operator network.

If the priority issuing module 62 judges that the terminal supports the 5G mode based on the terminal capability information, the MME sends a frequency priority policy to a base station of the first operator network to which the terminal is currently attached; wherein the base station controls the terminal to attach to a second operator network based on the frequency priority policy, the second operator network comprising: a 5G network of a second operator covering the network sharing area.

The terminal Capability obtaining module 61 receives a location registration request message or an attach request initiated by the terminal, and obtains terminal Capability information of the terminal according to information carried in a Capability field in the location registration request message or the attach request. When a terminal is started in a network sharing area, sending an attach request; when the terminal moves to the network shared area, a location registration request message is transmitted.

In one embodiment, the present disclosure provides a communication system comprising: a first operator network, a second operator network, a base station and a terminal of the first operator network, and an MME device as in any of the above embodiments.

In one embodiment, the present disclosure provides a computer-readable storage medium storing computer instructions for a processor to perform a terminal access control method as in any of the above embodiments.
