Among them, the PDU session is a protocol data unit session (Protocol Data Unit session, PDU session), which connects the PDU data between the user terminal and the data network (Data Network, DN), that is, the data between the user equipment and the data network Data transmission channel. It should be noted that, for the preset number of PDU sessions included in the user terminal, the preset number of PDU sessions is set according to the actual situation, which is not specifically limited in the embodiment of the present invention. For example, the user terminal uses It is the 3rd Generation Partnership Project (3GPP) protocol. The maximum number of PDU sessions that the user equipment can establish is 8 or more; the 8 PDU sessions establish multiple network slices, the 8 The number of PDU session establishment network slices can be set according to the actual situation, which is not specifically limited in the embodiment of the present invention. For example, the 8 PDU sessions establish 8 different network slices respectively, and for example, the 8 PDU sessions Two network slices are established respectively, that is, one network slice establishes 4 PDU sessions, and the other network slice establishes another 4 PDU sessions.

In an embodiment, when it is detected that a certain application on the user equipment is started, the application initiates a PDU session establishment request, and the session management apparatus obtains the PDU session establishment request from the application and obtains the currently established PDU The number of sessions, to get the number of PDU sessions. In one embodiment, one PDU session may correspond to one application program identifier, that is, one application program uses one PDU session, that is, the number of PDU sessions may be confirmed according to the application program identifier.

Step S102: When it is determined that the number of PDU sessions reaches the preset number, and the application has the right to use the PDU sessions, deactivate one of the established PDU sessions.

The preset number of PDU sessions is the number of PDU sessions that the user equipment can establish. The preset number can be set according to actual conditions. The embodiment of the present invention does not specifically limit this. For example, the user equipment uses It is a 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) protocol. The user equipment includes 8 PDU sessions, and the preset number is 8 or 10.

In an embodiment, the specific method for determining whether the application has the right to use the PDU session is to obtain a permission list of the PDU session, where the permission list stores the application identifiers of the applications that have the right to use the PDU session Symbol; Obtain the application identifier of the currently running application, and determine whether the application identifier of the currently running application is in the permission list. When it is determined that the application identifier of the currently running application is in the permission list, obtain the user account for logging in to the currently running application, and determine whether the user account is in the whitelist of the currently running application; when the user is determined When the account is in the whitelist of the currently running application, it is determined that the currently running application has the permission to use the PDU session; when it is determined that the user account is not in the whitelist of the currently running application, or the current running application When the application identifier is not in the permission list, it is determined that the currently running application does not have the permission to use the PDU session. Wherein, the whitelist of the application is a collection of application identifiers of the permission application used by the PDU session set by the user. The whitelist of the application can be set according to the actual situation, which is not specifically limited in the embodiment of the present invention. The user account can be selected according to the actual situation, and the embodiment of the present invention does not specifically limit this. For example, the user account can be the user's mobile phone account, and of course, it can also be any other suitable authority identity information.

It should be noted that the network slice selection assistance information (network slice selection assistance information, NSSAI) of the network operator’s network slice is mainly purchased through the application development company and the user account that has logged in to the application has purchased the application development company’s Only when you are a member, the app has the right to use the PDU session. Among them, the network operator can be determined according to actual conditions, and the embodiment of the present invention does not specifically limit this. For example, the network operator can select operators such as mobile operators, China Unicom operators, and telecommunications operators.

For example, when the application development company purchases the network slice selection auxiliary information of the network operator’s network slice, and the user account that logs in to the application does not purchase a member of the application development company, the application on the user’s device Does not have the right to use the PDU session.
