Session processing method and apparatus

1. A session processing method, comprising:

determining, by a processor, that a first application is not associated with at least one session parameter of a plurality of session parameters of a first session when starting the first application, wherein the first session is pre-existing prior to starting the first application; and

transmitting data of the first application through the first session in response to obtaining indication information rather than establishing a second session for the first application,

wherein

the indication information indicates that the first session is to be used for transmitting the data of the first application, and

the indication information is generated in response to:

a determination that a first session parameter of the plurality session parameters of the first session is not identical to a first session parameter requirement of a plurality of session requirements of the first application,

a determination that the first session parameter of the first session, though not identical to the first session parameter requirement of the first application, can satisfy the first session parameter requirement of the first application; and

a determination that a second session parameter of the first session is identical to a second session parameter requirement of the first application.

2. The method according to claim 1 , wherein transmitting the data of the first application comprises:

when the first session parameter of the first session is a network slice identifier of the first session, transmitting the data of the first application by using a network slice corresponding to the network slice identifier of the first session.

3. The method according to claim 1 , wherein transmitting the data of the first application comprises:

when the first session parameter of the first session is a data network identifier of the first session, transmitting the data of the first application by using a data network corresponding to the data network identifier of the first session.

4. The method according to claim 1 , wherein transmitting the data of the first application comprises:

when the first session parameter of the first session is a service and session continuity mode, transmitting the data of the first application based on the session continuity mode of the first session.

5. A session processing apparatus, comprising:

a processor configured to determine that a first application is not associated with at least one session parameter of a plurality of session parameters of a first session when a terminal device starts the first application, wherein the first session is pre-existing prior to starting the first application; and

a transmitter configured to transmit data of the first application through the first session in response to the terminal device obtaining indication information rather than establishing a second session for the first application,

wherein

the indication information indicates that the first session is to be used for transmitting the data of the first application, and

the indication information is generated in response to:

a determination that a first session parameter of the plurality session parameters of the first session is not identical to a first session parameter requirement of a plurality of session requirements of the first application,

a determination that the first session parameter of the first session, though not identical to the first session parameter requirement of the first application, can satisfy the first session parameter requirement of the first application; and

a determination that a second session parameter of the first session is identical to a second session parameter requirement of the first application.

6. The apparatus according to claim 5 , wherein

when the first session parameter of the first session is a network slice identifier of the first session, the transmitter is configured to transmit the data of the first application by using a network slice corresponding to the network slice identifier of the first session.

7. The apparatus according to claim 5 , wherein

when the first session parameter of the first session is a data network identifier of the first session, the transmitter is configured to transmit the data of the first application by using a data network corresponding to the data network identifier of the first session.

8. The apparatus according to claim 5 , wherein

when the first session parameter of the first session is a service and session continuity mode of the first session, the transmitter is configured to transmit the data of the first application based on a session continuity mode of the first session.

9. The apparatus according to claim 5 , wherein the apparatus is the terminal device.

10. A non-transitory computer readable medium having computer readable instructions stored thereon that, when executed by a processor, cause an apparatus to:

determine that a first application is not associated with at least one session parameter of a plurality of session parameters of a first session when starting the first application, wherein the first session is pre-existing prior to starting the first application; and

transmit data of the first application through the first session in response to obtaining indication information rather than establishing a second session for the first application,

wherein

the indication information indicates that the first session is to be used for transmitting the data of the first application, and

the indication information is generated in response to:

a determination that a first session parameter of the plurality session parameters of the first session is not identical to a first session parameter requirement of a plurality of session requirements of the first application,

a determination that the first session parameter of the first session, though not identical to the first session parameter requirement of the first application, can satisfy the first session parameter requirement of the first application; and

a determination that a second session parameter of the first session is identical to a second session parameter requirement of the first application.

11. The non-transitory computer readable medium according to claim 10 , wherein

when first the session parameter of the first session is a network slice identifier of the first session, the apparatus is caused to transmit the data of the first application by using a network slice corresponding to the network slice identifier of the first session.

12. The non-transitory computer readable medium according to claim 10 , wherein

when first the session parameter of the first session is a data network identifier of the first session, the apparatus is caused to transmit the data of the first application by using a data network corresponding to the data network identifier of the first session.

13. The non-transitory computer readable medium according to claim 10 , wherein

when first the session parameter of the first session is a service and session continuity mode, the apparatus is caused to transmit the data of the first application based on the session continuity mode of the first session.
