When people come to a new environment, people want to find out the things of interest in a certain range of the current location. This demand is increasing, and near field communication Services (ProSe) is becoming more popular with users. In practical applications, a merchant may send a broadcast message including service information to at least one Monitoring (Monitoring) UE within a preset distance range on a social application platform through a held broadcast User Equipment (UE). Correspondingly, the customer can monitor the broadcast message on the social application platform through the monitoring UE to acquire the service information.

In the prior art, no matter the UE is broadcasting or monitoring the UE to execute the proximity service, it needs to send a discovery request message to the proximity service server on the network side, and the UE may send the discovery request message to the proximity service server in different scenarios such as first request or network replacement. In any scenario, as long as the proximity service server receives the discovery request message, the UE is verified, and if the UE passes the verification, default parameter information is sent to the UE, where the parameter information may include broadcast information and valid duration, that is, in the same UE, in any scenario, the parameter information sent by the proximity service server for the UE is the same. And the air interface resources required by the UE to execute the proximity service are allocated by the base station, and the air interface resources allocated by the base station to the UE are the same regardless of the size of the proximity service simultaneously requested by the UE. In addition, in an equivalent network deployment scenario, as long as the UE moves within the range of the equivalent network of the UE to switch the registration network, the UE does not notify the proximity service Server and the Home Subscriber Server (HSS) of the home network of the network identifier after the switching, so that the proximity Server of the home network cannot notify the proximity Server of the current network to verify the UE after receiving the discovery request message sent by the UE.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The service authorization method provided by each embodiment of the present invention may be that the network side device authorizes the proximity service of the UE by executing the service authorization method, and allocates the parameter information of the proximity service to the UE after the authorization verification is passed, so that the UE can discover the proximity service according to the parameter information. The parameter information may include broadcast information corresponding to the proximity service requested by the UE, which is allocated by the network side device to the UE. The UE may be a broadcast UE or a monitoring UE, and the broadcast information may be a broadcast code or a monitoring code. The monitoring code at least includes the broadcast code, that is, the broadcast code may be identical to the monitoring code, or may be a part of the monitoring code. The network side device may be a proximity service server, or an HSS. The proximity service server may also be a proximity service Function (ProSe Function for short). The parameter information may further include: the validity period. The valid duration may be a valid duration corresponding to the broadcast information. If the UE is a broadcast UE, the validity period corresponding to the broadcast information may be represented by a broadcast timer, and if the UE is a monitoring UE, the validity period corresponding to the broadcast information may be represented by a monitoring timer. The broadcast timer may have a time period that is a valid time period for the broadcast UE to send the broadcast message, and the listening timer may have a time period that is a valid time period for the listening UE to receive the broadcast message.

Example one

The embodiment of the invention provides a service authorization method. The method may be performed by a proximity services server of a home network. Fig. 1 is a flowchart of a service authorization method according to an embodiment of the present invention. As shown in fig. 1, a service authorization method provided in this embodiment may include the following steps:

s101, a near field service server receives a discovery request message sent by UE; the discovery request message includes identification and indication information of the proximity service requested by the UE; the indication information is reason indication information for the UE to send the discovery request message.

Specifically, the proximity service server is a proximity service server of a home network of the UE. The UE Home Network may be a Home Public Land Mobile Network (HPLMN) of the UE. The home network of the UE may be a communication network provided by an operator to which a Subscriber Identity Module (SIM) of the UE subscribed to the UE belongs. If the UE is a broadcast UE, the proximity service server in S101 receives the discovery request message sent by the UE, which may be before the UE sends the broadcast message within a preset distance range to push the proximity service. If the UE is a monitoring UE, the proximity service server in S101 receives the discovery request message sent by the UE, which may be before the UE receives a broadcast message to acquire the proximity service.

The discovery request message may be a discovery request message of the proximity service, such as a discoverrequest message of the proximity service.

The UE may perform the discovery of the proximity service by sending a broadcast message based on the application platform to perform service push, or by receiving the broadcast message based on the application platform to obtain the proximity service information. Thus, the identification of the proximity service requested by the UE may include: an identifier of the proximity service on the Application platform (ProSe Application Identity, abbreviated as ProSe App ID), and an identifier of the Application platform (Application Identity, abbreviated as App ID). The ProSe App ID may be an identifier of a service that the server of the application platform has on the application platform for the UE allocated by the UE when the UE is registered and authenticated on the application platform. Wherein the ProSe App ID can be used to represent the content of the proximity service requested by the UE, such as a hotel, restaurant, florist, etc. The content of the proximity service may be determined by the holder of the UE, the services available, or the content of the services requested by the UE. If the UE is a broadcast UE, the proximity service may be a service requested to be broadcast by the UE, and may be determined by services available by the holder of the UE. If the UE is a listening UE, the proximity service may be a service requested to be received by the UE. The application platform can be a social application such as WeChat and microblog.

Wherein the indication information included in the discovery request message may be cause indication information for the UE to send the discovery request message.

If the UE is a broadcast UE, the indication information may be: initial indication information, deferred indication information, or handover registration network indication information. The initial indication information may be used to indicate that the discovery request message is a discovery request message that the UE first sends to the proximity service server to request the proximity service. The deferral indication information may be used to indicate that the discovery request message is a discovery request message sent by the UE to the proximity service server when the validity duration expires for the UE. The valid duration is the valid duration in the parameter information that the UE obtained from the proximity service server last time. The handover registration network indication message may be used to indicate that the discovery request message is a discovery request message sent to the proximity service server after the UE switches the registration network.

If the UE is a listening UE, the indication information may include: initial indication information, or deferred indication information. The initial indication information may be used to indicate that the discovery request message is a discovery request message that the UE first sends to the proximity service server to request the proximity service. The deferral indication information may be used to indicate that the discovery request message is a discovery request message sent by the UE to the proximity service server when the validity duration expires. The effective duration is the effective duration in the parameter information acquired by the UE from the proximity service server last time.

The different indication information may be represented by different identifiers. The short-distance service server can determine the indication information corresponding to the identifier according to the preset corresponding relation between the identifier and the indication information. For example, the embodiment of the present invention may represent the initial indication information by data 00, the postpone indication information by data 01, and the handover registration network indication information by data 10. The different indication information may also be initial indication information, deferred indication information, or handover registration network indication information, represented by A, B and C, respectively. The different indication information may also be represented by different character strings, such as a character string initial indicating information, a character string extension indicating information, and a character string change indicating information for switching the registered network.

S102, the short-distance service server verifies the UE according to the identification of the short-distance service.

The UE identifier may include a network identifier accessed by the UE, such as an International Mobile Subscriber Identity (IMSI) of the UE, or an International Integrated Services digital network Number (MSISDN) of a Mobile Station of the UE.

The authentication of the identifier of the proximity service to the UE by the proximity service server may be determined according to the identifier of the UE and the identifier of the proximity service, and if the proximity service server has the context information of the UE, the proximity service server further needs to determine whether the context information of the UE includes the identifier of the proximity service. And if the proximity service server has the context information of the UE and the context information of the UE comprises the identification of the proximity service, the proximity service server verifies the UE. If the proximity service server does not have the context information of the UE, or the context information of the UE does not include the identifier of the proximity service, the proximity service server further needs to send a discovery authentication request message to the HSS and receive a request response message corresponding to the discovery authentication request message returned by the HSS, where the request response message includes: and the HSS verifies the UE. And the short-distance service server creates context information for the UE according to the authentication result of the HSS to the UE.

The Discovery Authentication Request message may be a Discovery Authentication Request message, or may be another type of Request message. The discovery validation request message may include: the identity of the proximity service requested by the UE and the identity of the UE.

The HSS can perform service verification on the UE according to the identification of the proximity service and the identification of the UE. The HSS performs service verification on the UE, for example, the subscription information of the UE and the current network identifier of the UE are determined according to the identifier of the UE, whether the UE has the broadcast or reception capability of the proximity service is determined according to the subscription information of the UE and the identifier of the proximity service requested by the UE, and whether the UE has the broadcast or reception capability of the proximity service in the currently registered network is determined according to the current network identifier of the UE and the identifier information of the proximity service requested by the UE. The HSS determines that the UE has the broadcast or receiving capability of the proximity service by performing service verification on the UE, and can return the request response message to the proximity service server under the condition that the current registration network has the broadcast or receiving capability of the proximity service.

S103, if the UE passes the verification, the proximity service server distributes the parameter information of the proximity service to the UE according to the indication message.

Since the indication information may be: the different indication information may correspond to different parameter information, such as effective duration, respectively. The proximity service server may determine the parameter information corresponding to the indication information according to the indication information and the indication information parameter information correspondence table, and configure the parameter information corresponding to the indication information as the parameter information of the proximity service requested by the UE.

S104, the proximity service server sends a discovery response message to the UE, where the discovery response message includes the parameter information.

The discovery response message may be a discovery response message of the proximity service, such as a discovery response message of the proximity service.

The parameter information is determined by the proximity service server according to the indication information in the discovery request message sent by the UE, so that the resources actually required by the UE for performing proximity service are consistent with the resources corresponding to the parameter information, the resources of the UE can be more balanced, and the problems of resource waste and resource deficiency imbalance are solved.

The service authorization method provided by the embodiment of the invention can receive the discovery request message sent by the UE through the short-distance service server, wherein the discovery request message comprises the identification and the indication information of the short-distance service requested by the UE, and the short-distance service server verifies the UE according to the identification of the short-distance service; if the UE passes the verification, the proximity service server allocates the parameter information of the proximity service to the UE according to the indication information, and sends the parameter information to the UE through the discovery response message, so that the UE can execute the proximity service according to the parameter information allocated according to the indication information, the resources actually required by the UE for performing the proximity service are consistent with the resources corresponding to the parameter information, and the resources of the UE are more balanced.

Example two

The second embodiment of the invention also provides a service authorization method. Optionally, in the service authorization method in the first embodiment of the present invention, the indication information may be delay indication information.

The deferral indication information is used to indicate that the discovery request message is a discovery request message sent by the UE to the proximity service server when the validity duration of the proximity service server for the UE expires. Wherein, the valid duration is the valid duration in the parameter information obtained by the UE from the proximity service last time.

If the UE is a broadcast UE, the expiration of the valid duration may refer to expiration of a broadcast timer corresponding to a broadcast code. If the UE is a monitoring UE, the expiration of the valid duration may also mean that a monitoring timer corresponding to the monitoring code expires.

Optionally, in the first embodiment as described above, in S102, the allocating, by the proximity service server, the parameter information of the proximity service to the UE according to the indication information may include:

the short-distance service server distributes the parameter information to the UE according to the delay indication information; the effective duration in the parameter information is longer than the effective duration in the parameter information acquired by the UE from the proximity service server last time.

Specifically, if the indication information is the postponed indication information, the effective duration in the parameter information allocated by the proximity service server to the UE is longer than the effective duration in the parameter information acquired by the UE from the proximity service server last time, which can ensure the consistency of performing the proximity service, avoid the UE initiating a discovery request to the proximity service server many times, and reduce signaling interaction while ensuring the performance of the proximity service.

The second embodiment of the present invention further provides another service authorization method, and the method may specifically describe the service authorization method in the first embodiment or the second embodiment by using a specific example. The second embodiment of the present invention is described only with the service authorization method when the UE is a broadcast UE, and the service authorization method when the UE is a monitor UE is similar to that when the UE is a broadcast UE, and is not described herein again. Fig. 2 is a flowchart of a service authorization method according to a second embodiment of the present invention. As shown in fig. 2, the method may include:

s201, the UE acquires the ProSe App ID of the short-distance service.

The broadcast UE may acquire the service identifier, which is allocated to the broadcast UE by the server of the application platform, on the application platform by registering on the application platform, such as a WeChat or a microblog. If the holder of the broadcast UE is a merchant and the application platform is wechat, the ProSe App ID may be a service identifier for registration authentication of the broadcast UE on wechat.

S202, the UE sends a discovery request message to the proximity service server, wherein the discovery request message comprises the ID of the UE, the ProSe App ID, the postponement indication information and the type of the UE.

The ID of the UE may be an ID of the UE accessing the network, and the App ID is an ID of an application platform, such as a microblog, a WeChat, and the like. The deferral indication information is used to indicate that the discovery request message is a discovery request message sent by the UE to the proximity service server if the validity duration expires. The valid duration is the valid duration in the parameter information acquired by the UE from the proximity service server last time, and the type of the UE may be represented by an identifier corresponding to a role of the UE. For example, if the UE is a UE that transmits broadcast information including the proximity service information, the UE is a broadcast UE, and the type of the UE may be represented by a character string announce; correspondingly, if the UE is a UE receiving the broadcast information including the proximity service information, the UE is a monitoring UE, and the type of the UE may be represented by a character string monitoring.

S203, the short-distance service server verifies the UE according to the ID of the UE, the ProSe App ID, the App ID and the type of the UE.

The proximity service server verifies the UE, which may be to determine whether the UE has context information including a ProSe App ID and an App ID.

S204, if the short-distance service server passes the verification of the UE, the short-distance service server distributes parameter information to the UE according to the postponing indication information, wherein the parameter information comprises: broadcast information and validity duration; wherein the effective duration in the parameter information is longer than the effective duration in the parameter information that the UE obtained from the proximity service server last time.

The broadcast information may be a broadcast code, and the valid duration is a broadcast timer corresponding to the broadcast code.

The proximity service server verifies the UE, which means that the proximity service server has the context information of the UE including the ProSe App ID and the App ID.

S205, if the proximity service server fails to authenticate the UE, the proximity service server sends a discovery authentication request message to the HSS, where the discovery authentication request message includes an ID of the UE.

The proximity service server fails the UE authentication, meaning that the proximity service server does not have the context information of the UE including the ProSe App ID and/or App ID.

S206, the HSS inquires the subscription information of the UE according to the ID of the UE and verifies the UE according to the subscription information of the UE.

The HSS verifies the UE, which may be to determine whether the UE signs up for the proximity service and whether the UE has the capability to execute the proximity service.

S207, if the HSS verifies the UE, the HSS returns a request response message corresponding to the discovery and verification request message to the proximity service server, where the request response message may include a verification result of the HSS for the UE.

The HSS verifies the UE, that is, the UE signs up for the proximity service, and the UE has the capability of executing the proximity service.

S208, the short-distance service server creates context information of the UE according to the verification result of the UE, and distributes parameter information to the UE according to the postponed indication information, wherein the parameter information comprises: broadcast information and validity duration; wherein the effective duration in the parameter information is longer than the effective duration in the parameter information that the UE obtained from the proximity service server last time.

S209, the distance service server returns a discovery request response message to the UE, where the discovery request response message includes the parameter information, and the parameter information includes broadcast information and validity duration.

In the service authorization method provided in the second embodiment of the present invention, the proximity service server may allocate parameter information to the UE according to the deferral indication information sent by the UE, so that resources actually required by the UE for performing the proximity service are consistent with resources corresponding to the parameter information, and the resources of the UE are more balanced, and meanwhile, since the effective duration in the parameter information is longer than the effective duration that the UE obtained from the proximity service server last time, the second embodiment of the present invention may further ensure continuity of executing the proximity service, avoid that the UE initiates a discovery request to the proximity service server for multiple times, and reduce signaling interaction while ensuring execution of the proximity service.

EXAMPLE III

The third embodiment of the invention also provides a service authorization method. The method may be performed by a proximity services server of a home network. Fig. 3 is a flowchart of a service authorization method provided by the third embodiment of the present invention. As shown in fig. 3, the service authorization method provided in the third embodiment may include the following steps:

s301, a short-distance service server receives a discovery request message sent by UE; the discovery request message includes an identifier of the proximity service requested by the UE and initial indication information; the initial indication information is used for indicating that the discovery request message is a discovery request message which is firstly sent to the proximity service server by the UE for requesting the proximity service.

S302, the proximity service server determines the number of proximity services requested by the UE according to the discovery request message including the initial indication information sent by the UE.

The UE sends a discovery request message including initial indication information to the proximity service server every time it requests a new proximity service. The proximity service server may update a value of a counter of the UE according to a discovery request message including the initial indication information sent by the UE, and determine the updated value of the counter of the UE as the number of proximity services requested by the UE. The proximity service server updates the value of the counter of the UE, which may be an operation of adding one to the value of the counter of the UE.

It should be noted that, before updating the value of the counter of the UE, the proximity service server further determines whether the number of proximity services in the context information of the UE is the same as the value of the counter of the UE, and if not, corrects the value of the counter of the UE according to the number of proximity services in the context information of the UE, so that the number of proximity services in the context information of the UE is consistent with the value of the counter of the UE. The validity duration of each proximity service in the context information of the UE is in the validity period, that is, the validity duration has not expired. If the validity duration of a certain proximity service of the UE expires, the proximity service server further needs to delete the information of the certain proximity service in the context information of the UE.

S303, the proximity service server sends a resource request message to a base station, where the resource request message includes the number of the proximity service, and the resource request message is used to instruct the base station to allocate air interface resources to the UE according to the number of the proximity service.

The proximity service server may be sequentially transmitted to the base station through the HSS and a Mobile Management Entity (MME). The base station may be an evolved Node B (eNB).

Because the base station may allocate air interface resources to the UE according to the number of the proximity services, the larger the number of the proximity services is, the larger the air interface resources allocated to the UE by the base station is, and correspondingly, the smaller the number of the proximity services is, the smaller the air interface resources allocated to the UE by the base station is.

Optionally, before the sending, by the proximity service server, the resource request message to the base station in S303, the method further includes:

and the near field service server determines to increase the air interface resources required by the UE according to the number of the near field services and a preset service number threshold.

The service quantity threshold is the near field service quantity included in the resource request message which is sent by the near field service server to the base station last time and is used for requesting air interface resources.

Correspondingly, the sending, by the proximity service server, the resource request message to the base station in S303 may include:

and if the near field service server determines to increase the air interface resources required by the UE, the near field service server sends the resource request message to the base station.

Specifically, the proximity service server sends the resource request message to the base station only when it is determined that the air interface resource required by the UE is increased, so that interaction between the proximity service server and the base station can be reduced when it is ensured that the air interface resource required by the UE is sufficient.

The determining, by the proximity service server according to the number of the proximity services and the preset service number threshold, to increase the air interface resources required by the UE may include:

the short-distance service server compares the number of the short-distance services with the threshold value of the number of the services;

and if the quantity of the short-distance services is larger than the service quantity threshold value, the short-distance service server determines to increase the air interface resources required by the UE.

In the service authorization method provided in the third embodiment of the present invention, when the indication information may also be initial indication information, the proximity service server determines, according to a discovery request message that includes the initial indication information and is sent by the UE, the number of proximity services requested by the UE, the proximity service server sends a resource request message to a base station, the resource request message includes the number of the proximity services, and the resource request message is used to instruct the base station to allocate air interface resources to the UE according to the number of the proximity services, so that the larger the number of the proximity services is, the larger the air interface resources allocated to the UE by the base station are, correspondingly, the smaller the number of the proximity services is, and the smaller the air interface resources allocated to the UE by the base station are. Meanwhile, in the third embodiment, the near field service server sends the resource request message to the base station only when determining that the air interface resource required by the UE is added, so that the interaction between the near field service server and the base station can be reduced when ensuring that the air interface resource required by the UE is sufficient.

EXAMPLE five

The fifth embodiment of the invention also provides a service verification method. The method may be performed by a proximity services server of a home network. Fig. 5 is a flowchart of a service authorization method according to a fifth embodiment of the present invention. As shown in fig. 5, the service authorization method provided in this embodiment 5 may include the following steps:

s501, a proximity service server receives a discovery request message sent by UE, wherein the discovery request message comprises identification and indication information of proximity service requested by the UE; the indication information is reason indication information for the UE to send the discovery request message.

S502, the proximity service server determines, according to the number of discovery request messages including the indication information sent by the UE, the number of times that the UE requests the proximity service within a preset time period.

It should be noted that, in S502, the proximity service server determines, according to the number of discovery request messages including the indication information, the number of times that the UE requests the proximity service in a preset time period, where the number of times that the proximity service server performs the proximity service request in the preset time period may be counted by the proximity service server for the discovery request messages sent by the UE in the preset time period, and then the number of the discovery request messages including the initial indication information or the postponed indication information is determined as the number of times that the proximity service request is performed. The preset time period may be a time period from the starting time, such as any one of a day, a week, or a month. The start time may be a time when the UE signs up for the proximity service. The starting time may also be a predetermined specific time point, such as any one of time points from 0 to 24 per day, or any one day from monday to sunday.

S503, the proximity service server determines the priority of the UE according to the number of the proximity service requests and the corresponding relation between the number of the proximity service requests and the priority.

Specifically, the correspondence between the number of requests for the proximity service and the priority may be stored in a correspondence table between the number of requests and the priority. The correspondence table of the number of requests and the priority may include: at least two priorities and a request number range corresponding to each priority in the at least two priorities.

In the preset correspondence table of request times and priorities, one priority may correspond to one request time range. The proximity service server may determine a request frequency range to which the number of times of requesting the proximity service belongs according to the number of times of requesting the proximity service, and determine a priority corresponding to the request frequency range to which the number of times of requesting the proximity service belongs in the preset request frequency and priority correspondence table according to the request frequency range to which the number of times of requesting the proximity service belongs, as the priority of the UE.

For example, if the preset correspondence table between the number of requests and the priority is shown in table 1 below:

priority level	Number of requests
		General users	0～19
Silver card user	20～99
		Gold medal user	≥100

TABLE 1

If the number of times of requesting the proximity service by the UE is determined to be 50 by the proximity service server, it can be known from the preset correspondence table between the number of times of requesting and the priority that 50 falls within the range of 20 to 99, and therefore, the priority of the UE is a bank user. If the number of times of requesting the proximity service by the UE is determined to be 100 by the proximity service server, it can be known from the preset correspondence table between the number of times of requesting and the priority that 100 belongs to a range of not less than 100, and therefore, the priority of the UE is a gold medal user.

It should be noted that table 1 is only one implementation example of the preset correspondence table between the number of requests and the priority, and the priority in table 1 may also include other types of priorities, and the number of requests corresponding to each priority may also be in other numerical ranges, which is not described herein again.

The near field service server can charge the near field service executed by the UE according to the priority of the UE, and the continuity of the near field service of the UE when the network is busy is ensured. The proximity service server can also perform roaming permission and the like for the UE which is switched to the registered network according to the priority of the UE.

The service authorization method provided by the fifth embodiment of the present invention may determine the priority of the UE by counting the number of times that the proximity service server requests the proximity service from the UE, so that the proximity service server may charge the proximity service executed by the UE according to the priority of the UE, thereby ensuring the continuity of the proximity service of the UE when the network is busy.

Optionally, the method further includes:

and the short-distance service server sends the priority of the UE to the HSS so that the HSS judges whether the priority of the UE changes or not according to the priority of the UE and the priority in the subscription information of the UE.

If the priority of the UE changes, the HSS also modifies the priority in the subscription information of the UE into the priority of the UE.

The priority change of the UE may include a priority increase of the UE or a priority decrease of the UE.

Optionally, the indication information is initial indication information or deferred indication information.

Wherein, the initial indication information is used to indicate that the discovery request message is a discovery request message that is sent by the UE to the proximity service server for requesting the proximity service for the first time; the deferral indication information is used for indicating that the discovery request message is a discovery request message sent by the UE to the proximity service server when the validity duration of the proximity service server for the UE expires. Wherein, the valid duration is the valid duration in the parameter information obtained by the UE from the proximity service last time.

In the service verification method of the fifth embodiment of the present invention, the number of times that the proximity service server requests the proximity service of the UE may be counted by the proximity service server to determine the priority of the UE, so that the proximity service server determines whether the priority of the UE changes, and when the priority of the UE changes, modifies the priority in the subscription information of the UE into the priority of the UE, so that the proximity service server may perform maintenance statistics on the priority of the UE, so that the HSS performs correction maintenance on the priority of the UE, and better ensures correspondence between the subscription information of the UE and the priority.

s701, a short-distance service server receives a discovery request message sent by UE, wherein the discovery request message comprises switching registration network indication information and a current registration network identifier of the UE; the handover registration network indication message is used to indicate that the discovery request message is a discovery request message sent to the proximity service server after the UE switches the registration network.

S702, the proximity service server determines that the current registered network identifier of the UE is a network identifier in the equivalent network identifier list of the UE, and the current network identifier of the UE is different from the registered network identifier in the context information of the UE.

S703, the proximity service server updates the registered network identifier in the context information of the UE according to the current registered network identifier of the UE.

The current registered Network identifier of the UE may be an identifier of a registered Network when the UE performs Network attachment last time, that is, an identifier of a Serving Public land mobile Network (VPLMN) that provides communication service for the UE currently. Different mobile communication networks have different network numbers, communication networks provided by different operators have different network numbers, and different communication networks provided by the same operator also have different communication numbers. The operator may be, for example, china mobile, china unicom, china telecom, AT & T, etc. For example, if the network currently providing communication service for the UE, that is, the network provided by the VPLMN for the china unicom operator, the identity of the VPLMN may be 46001.

The equivalent network identifier list of the UE is a network identifier list that includes at least one network identifier of a Location Area (LA) allocated to the UE by a home network after the UE is attached to the home network. When the UE moves within the LA, that is, when each network within the LA migrates, it is not necessary to notify the network side device. The equivalent network identity may be denoted as LA list comprising at least one network identity, i.e. an identity of at least one PLMN.

If the current registered network identifier of the UE is a network identifier in the equivalent network identifier list of the UE, and the current network identifier of the UE is different from the registered network identifier in the context information of the UE, that is, the UE moves within the equivalent network range of the UE in an equivalent network deployment scenario, and switches the registered network.
