As shown in fig. 1, the session management method may include steps S101 to S103.
Step S101, acquiring a Protocol Data Unit (PDU) session establishment request initiated by an application program, and acquiring the number of established PDU sessions to obtain the number of PDU sessions.
The PDU session is a Protocol Data Unit session (PDU session), and the PDU session connects PDU Data between a user equipment and a Data Network (DN), that is, a Data transmission channel between the user equipment and the Data Network. It should be noted that, the preset number of PDU sessions included in the ue is set according to an actual situation, which is not specifically limited in the embodiment of the present invention, for example, the ue uses a third Generation Partnership Project (3 GPP) protocol, and the maximum number of PDU sessions that can be established by the ue is 8 or more; the 8 PDU sessions establish multiple network slices, and the number of the 8 PDU sessions establishing network slices may be set according to actual situations, which is not specifically limited in the embodiment of the present invention, for example, 8 different network slices are respectively established for the 8 PDU sessions, and for example, two network slices are respectively established for the 8 PDU sessions, that is, one network slice establishes 4 PDU sessions, and the other network slice establishes the other 4 PDU sessions.
In an embodiment, when detecting that a certain application program on the user equipment is started, the application program initiates a PDU session establishment request, and the session management apparatus obtains the PDU session establishment request from the application program, and obtains the number of currently established PDU sessions to obtain the number of PDU sessions. In one embodiment, one PDU session may correspond to one application identifier, that is, one application uses one PDU session, that is, the number of PDU sessions may be confirmed according to the application identifier.
And step S102, when the PDU conversation number is determined to reach the preset number and the application program has the authority of using the PDU conversation, carrying out deactivation processing on one PDU conversation in the established PDU conversation.
The preset number of PDU sessions is a number of PDU sessions that can be established by the ue, and the preset number may be set according to an actual situation, which is not specifically limited in the embodiment of the present invention, for example, the ue uses a 3rd Generation Partnership Project (3 GPP) protocol, the ue includes 8 PDU sessions, and the preset number is 8 or 10.
In an embodiment, the specific way of determining whether the application has the right to use the PDU session is as follows: acquiring an authority list of the PDU session, wherein an application program identifier of an application program with the authority of using the PDU session is stored in the authority list; and acquiring the application program identifier of the currently running application program, and determining whether the application program identifier of the currently running application program is positioned in the permission list. When the application program identifier of the currently running application program is determined to be located in the authority list, acquiring a user account for logging in the currently running application program, and determining whether the user account is located in a white list of the currently running application program; when the user account is determined to be in a white list of the currently running application program, determining that the currently running application program has the permission to use the PDU session; and when the user account is determined not to be in the white list of the currently running application program or the application program identifier of the currently running application program is determined not to be in the permission list, determining that the currently running application program does not have the permission to use the PDU session. The white list of the application program is a set of application program identifiers of an authority application program used by the PDU session set by the user, and the white list of the application program can be set according to actual conditions, which is not specifically limited in the embodiment of the present invention; the user account may be selected according to an actual situation, which is not specifically limited in the embodiment of the present invention, and for example, the user account may be a mobile phone account of the user, and may also be any other suitable authority identity information.
It should be noted that, when the Network Slice Selection Assistance Information (NSSAI) of the network slice of the network operator is purchased mainly by the development company of the application program and the user account number of the login application program purchases a member of the development company of the application program, the application program has the authority to use the PDU session. The network operator may be determined according to actual conditions, which is not specifically limited in the embodiment of the present invention, for example, the network operator may select an operator such as a mobile operator, a unicom operator, and a telecommunications operator.
For example, when a development company of an application purchases network slice selection assistance information of a network slice of a network operator, a user account logged in the application does not purchase a member of the development company of the application, and the application on the user equipment does not have a usage right of a PDU session.
In an embodiment, as shown in fig. 2, step S102 may include sub-steps S1021 through S1023.

When the fact that the identifier of the application program of each established PDU session is located in the identifier list of the preset application program is determined to be absent, each PDU session is sequenced according to the established length of time of each PDU session to obtain a PDU session queue, and the sub-optimal level of deactivation of each established PDU session is determined according to the sequence of each established PDU session in the PDU session queue. Wherein, the longer the duration of the PDU session establishment, the higher the priority of the deactivation of the PDU session.
It should be noted that, the above several ways of determining the deactivation priority of each established PDU session may determine the deactivation priority of each established PDU session in one way, or may combine the ways of determining the deactivation priority of each established PDU session in combination of several ways, so as to determine the deactivation priority of each established PDU session, which is not specifically limited in this embodiment of the present invention.
And a substep S1022, determining a target PDU session to be deactivated according to the established deactivation priority of each PDU session.
