Abstract

Claims (37)

1. A method, comprising:

determining, by a session management function network element, a service type corresponding to a terminal device;

sending, by the session management function network element and to a data analytics network element, a request message comprising an indication of the service type;

receiving, by the session management function network element, from the data analytics network element, and in response to the request message, first service experience analytics data corresponding to the service type, wherein the first service experience analytics data comprises an identifier of at least one application and predicted service experience information for the at least one application; and

selecting, by the session management function network element and based on the first service experience analytics data including the predicted service experience information for the at least one application, a first user plane path for a session of the terminal device.

2. The method of claim 1 , wherein selecting the first user plane path comprises selecting the first user plane path when the session is being established.

3. The method of claim 1 , further comprising obtaining first identification information of the first user plane path and the first service experience analytics data.

4. The method of claim 3 , wherein the request message comprises second identification information of the service type and a filter condition, wherein the filter condition determines the first identification information, wherein the first identification information corresponds to the second identification information, and wherein obtaining the first identification information and the first service experience analytics data comprises receiving, from the data analytics network element in response to the request message, the first identification information and the first service experience analytics data.

5. The method of claim 1 , wherein after selecting the first user plane path, the method further comprises:

determining that the first user plane path cannot meet a service experience requirement of a service initiated by the terminal device on the session; and

reselecting, based on second service experience analytics data corresponding to the service, a second user plane path for the service.

6. The method of claim 1 , wherein selecting the first user plane path comprises selecting a user plane function network element in the first user plane path.

7. The method of claim 6 , wherein selecting the first user plane path further comprises selecting a media plane server in the first user plane path.

8. The method of claim 1 , wherein the first service experience analytics data further comprises location information and a data network access identifier (DNAI) for the at least one application.

9. An apparatus, comprising:

one or more processors; and

a memory coupled to the one or more processors and configured to store instructions, wherein the instructions, when executed by the one or more processors, cause the apparatus to:

determine a service type corresponding to a terminal device;

send, to a data analytics network element, a request message comprising an indication of the service type;

receive, from the data analytics network element in response to the request message, first service experience analytics data corresponding to the service type, wherein the first service experience analytics data comprises an identifier of at least one application and predicted service experience information for the at least one application; and

select, based on the first service experience analytics data including the predicted service experience information for the at least one application, a first user plane path for a session of the terminal device.

10. The apparatus of claim 9 , wherein the instructions, when executed by the one or more processors, further cause the apparatus to select the first user plane path when the session is being established.

11. The apparatus of claim 9 , wherein the instructions, when executed by the one or more processors, further cause the apparatus to obtain first identification information of the first user plane path and the first service experience analytics data.

12. The apparatus of claim 11 , wherein the request message comprises second identification information of the service type and a filter condition, wherein the filter condition determines the first identification information, wherein the first identification information corresponds to the second identification information, and wherein the instructions, when executed by the one or more processors, further cause the apparatus to obtain the first identification information and the first service experience analytics data by receiving, from the data analytics network element in response to the request message, the first identification information and the first service experience analytics data.

13. The apparatus of claim 9 , wherein the instructions, when executed by the one or more processors, further cause the apparatus to:

determine that the first user plane path cannot meet a service experience requirement of a service initiated by the terminal device on the session; and

reselect, based on second service experience analytics data corresponding to the service, a second user plane path for the service.

14. The apparatus of claim 9 , wherein the apparatus is a session management network element, and wherein the instructions, when executed by the one or more processors, further cause the apparatus to select a user plane function network element in the first user plane path.

15. The apparatus of claim 14 , wherein the instructions, when executed by the one or more processors, further cause the apparatus to select a media plane server in the first user plane path.

16. The apparatus of claim 9 , wherein the apparatus is a service server, and wherein the instructions, when executed by the one or more processors, further cause the apparatus to select a media plane server in the first user plane path.

17. A computer program product comprising computer-executable instructions stored on a non-transitory computer-readable storage medium that, when executed by one or more processors, cause an apparatus to:

determine a service type corresponding to a terminal device;

send, to a data analytics network element, a request message comprising an indication of the service type;

receive, from the data analytics network element in response to the request message, first service experience analytics data corresponding to the service type, wherein the first service experience analytics data comprises an identifier of at least one application and predicted service experience information for the at least one application; and

select, based on the first service experience analytics data including the predicted service experience information for the at least one application, a user plane path for a session of the terminal device.

18. The computer program product of claim 17 , wherein the computer-executable instructions further cause the apparatus to select the user plane path when the session is being established.

19. The computer program product of claim 17 , wherein the request message further comprises a filter condition, and wherein the filter condition comprises slice information and place information.
