It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having meanings consistent with their meanings in the context of the related technology and the present disclosure, and will not be interpreted as having idealized or excessive formal meanings, Unless the present disclosure is specifically so limited.

In the first aspect, referring to FIG. 1, an embodiment of the present disclosure provides a method for issuing an access classification matching policy, which may include step S101 and step S102.

In step S101, according to preset corresponding rules, an access classification matching strategy corresponding to the access parameters of the target terminal is determined.

Wherein, the target terminal is a terminal that accesses the mobile communication network, and the access parameter is a parameter of the situation that the target terminal accesses the mobile communication network, and the access classification matching strategy is used to determine the access classification corresponding to the application in the target terminal.

A terminal is also called a user terminal (UE), which must have the ability to run applications and have access to a mobile communication network. For example, the terminal can be a smart phone, a tablet computer, etc. The target terminal is the target terminal issued by the access classification matching strategy.

Of course, it should be understood that there are usually many terminals simultaneously accessing a mobile communication network, so these terminals can be used as target terminals respectively, and the access classification matching strategies are respectively issued to them through the method of the embodiments of the present disclosure.

The mobile communication network (such as the 5G network) can query the access parameters of the target terminal (or the SIM card in the target terminal). Access parameters are related parameters for the target terminal to access the mobile communication network. For example, the target terminal's service status (such as voice service, data traffic service, short message service, etc.), and the type of network it belongs to (such as 4G network, 5G network) , The type of package selected, the remaining package resources, etc.

According to the predetermined corresponding strategy, the mobile communication network can determine the access parameters for the target terminal, what is the corresponding access category matching strategy, or determine the operator-defined access category definitions. In some embodiments, the specific content of the Operator-defined access category definitions can be found in section 8.2.7.24 of the 24.501 protocol.

The access category matching strategy is used for the terminal to determine which access category each application belongs to. For example, the access categories numbered 0 to 7 (Access category (0-7)) are standardized categories, and the matching strategy can be determined locally by the terminal; while the access categories numbered 32 to 63 (Access category (32-63)) are standardized It is a custom classification, and its matching strategy is the access classification matching strategy issued above.

Specifically, the access category matching policy may include multiple access category matching rules (Operator-defined access category definition), and each access category matching rule includes access category number (Access category number), priority, and applied Matching conditions, etc. Among them, the access classification number is the above number, the priority indicates the priority of the access classification matching rule, and the matching condition is used to match the parameters of the application, which may include single mesh selection auxiliary information (S-NSSAI, Single Network Slice Selection Assistance Information), application system type (such as iOS system or Android system), digital data network (DNN) information, etc. In this way, the terminal can determine the access classification matching rule corresponding to the application according to the matching conditions of which access classification matching rules match the parameters of an application, and determine the access classification matching rule priority and classification number according to the access classification matching rule. The specific access category corresponding to the application.

Each access category defines its corresponding access authority, network, traffic, billing, etc., that is, defines how applications belonging to the access category should access the mobile communication network.

Therefore, according to the access classification matching strategy, the target terminal can determine the access classification corresponding to each application of its own, that is, determine how each application should access the mobile communication network, and realize the unified access control (UAC, Unified Access Control) of the application. ).

In step S102, the access classification matching strategy is sent to the target terminal.

After the mobile communication network determines the access classification matching strategy corresponding to the access parameters of the target terminal, it sends the access classification matching strategy to the target terminal for use by the target terminal.

In the embodiments of the present disclosure, a special access classification matching strategy is configured for each terminal according to the specific conditions (access parameters) of each terminal, so the access classification matching strategy of each terminal is adapted to its own situation (for example, the terminal opens a service). In addition, when the terminal situation changes, the embodiments of the present disclosure can also update the corresponding access classification matching strategy for the terminal according to the changed situation in time.

In some embodiments, referring to FIG. 2, according to preset corresponding rules, determining an access classification matching strategy corresponding to the access parameters of the target terminal (S101) includes: the policy control function module of the mobile communication network according to the preset corresponding The rule determines the access classification matching strategy corresponding to the access parameters of the target terminal stored in it.

The above steps of determining the access classification matching strategy may be implemented by the policy control function module (PCF, Policy Control Function) of the mobile communication network.

The PCF module is used to manage various strategies in the mobile communication network, which usually stores the access parameters of each terminal. Therefore, the PCF module can directly determine the access classification matching strategy, which is more convenient.

In some embodiments, referring to FIG. 2, sending the access classification matching strategy to the target terminal (S102) includes: sending the access classification matching strategy to the target terminal through the access and mobility management function module of the mobile communication network.

The above access classification matching strategy may be sent (or forwarded) to the target terminal through the Access and Mobility Management Function (AMF, Access and Mobility Management Function) module.

The AMF module is used to manage the access, registration, etc. of each terminal in the mobile communication network, so it can be used to conveniently deliver information to the terminal.

In an exemplary embodiment, the access classification matching policy is added to the terminal policy (UE policy) and sent.

After the terminal accesses the mobile communication network, it needs to use the UE policy to operate. To this end, the above access classification matching strategy can be added to the UE strategy (that is, the access classification matching strategy is part of the UE strategy), and the access classification matching strategy is also included in the process of sending the UE strategy to the target terminal. Send together, so there is no need to set up a separate sending process.

Of course, it should be understood that the method of the embodiments of the present disclosure can also be implemented by other modules other than the PCF module and the AMF module, as long as the functions of the above steps can be realized, and the detailed description is omitted here.

In some embodiments, referring to FIG. 3, before determining the access classification matching strategy corresponding to the access parameters of the target terminal (S101), the method further includes: step S1001, receiving a registration request or an update registration request of the target terminal .

Between determining the access classification matching strategy corresponding to the access parameters of the target terminal (S101) and sending the access classification matching strategy to the target terminal (S102), the method further includes: step S1002, sending registration to the target terminal Accept feedback or update Accept feedback.

Obviously, the process of issuing the access classification matching strategy does not need to be continuously performed, but only needs to be performed under certain conditions, that is, it needs to be "triggered" by certain conditions.

As a specific way, the operation of issuing the access classification matching strategy can be triggered according to the registration request or update registration request of the target terminal.

Specifically, referring to Figures 2 and 3, when the target terminal is powered on or ready to access the mobile communication network again, it will send a registration request to the mobile communication network (for example, to the AMF module); the AMF module can respond to the registration request after receiving the registration request. It processes and decides whether to accept the registration. If it is determined that the registration is acceptable, the AMF module sends a request to establish a UE policy to the PCF module, requesting the PCF module to generate a UE policy including the above access classification matching strategy, and the AMF module also needs to report to the target The terminal sends registration acceptance feedback to enable the target terminal to register and access the mobile communication network; after that, the PCF module obtains the above access classification matching strategy, adds it to the UE strategy, and issues it through the AMF module (the issue includes access Enter the UE strategy of the classification matching strategy) to the target terminal.

Or, when the target terminal needs to update the registration due to location changes, etc., it also needs to send an update registration request (such as a mobility update registration request) to the AMF module. At this time, the AMF module can also update the target terminal according to the update registration request. Register (send updates to accept feedback), and require the PCF module to generate a new access classification matching strategy.

In some embodiments, referring to FIG. 4, before determining the access classification matching strategy corresponding to the access parameters of the target terminal (S101), the method further includes: step S1003, receiving a change in the access parameters of the target terminal Information; and/or, receive information about changes in the corresponding rules.

When the access parameters of the target terminal are changed (such as when the target terminal signs a new service or unsubscribes an existing service), or when it is determined that the operator wants to change the rules (ie corresponding rules) that generate the access classification matching strategy, the target The access classification matching strategy corresponding to the terminal will also change theoretically; therefore, when the PCF module obtains the information that has undergone the above changes, it should also actively re-determine the access classification matching strategy and issue it.

Of course, the conditions that cause the process of issuing the access classification matching strategy are not limited to the above examples. For example, this step can also be performed periodically or according to the request of the target terminal, etc., which will not be described in detail here.

Of course, in the method for issuing an access classification matching policy in the embodiment of the present disclosure, the AMF module can also issue a fixed access classification matching policy stored by itself to the target terminal (for example, for the PCF module that cannot issue the access classification When the matching strategy is used as a backup); among them, if both the AMF module and the PCF module are to issue the access classification matching strategy, the PCF module's access classification matching strategy should be given priority.

In the second aspect, referring to FIG. 5, an embodiment of the present disclosure provides an apparatus for issuing an access classification matching policy, which includes: a corresponding unit configured to determine the corresponding access parameter of the target terminal according to a preset corresponding rule Access classification matching strategy; among them, the target terminal is a terminal accessing the mobile communication network, and the access parameters are the parameters of the target terminal accessing the mobile communication network. The access classification matching strategy is used to determine the corresponding application in the target terminal Access classification; the sending unit is configured to send the access classification matching strategy to the target terminal.
