Abstract
This application provides a communication method and apparatus, relating to the field of communication technologies. In the method, when update of an MBS service area of a service for which a multicast/broadcast session has been established to a first service area fails, an MBS device can also trigger continuation of establishing a multicast/broadcast session for the service, allowing a subsequently established multicast/broadcast session to provide the service for the first service area. In this way, continuity of the service can still be ensured when the update of the MBS service area fails.
Claims20
A communication method, performed by a multicast/broadcast service (MBS) device or a chip in an MBS device, wherein the method comprises:
- sending first information to a first network capability exposure function network element, wherein the first information is for requesting to update an MBS service area to a first service area, and the MBS service area is a service area of a service;
- receiving second information from the first network capability exposure function network element, wherein the second information indicates that update of the MBS service area fails;
- and
- sending third information based on the second information, wherein the third information comprises information about the first service area, and the third information is for triggering establishing a multicast/broadcast session for the service.
A communication apparatus, comprising:
- a processor;
- and
- a memory coupled to the processor and storing computer program for execution by the processor to cause the communication apparatus to:
- send first information to a first network capability exposure function network element, wherein the first information is for requesting to update a multicast/broadcast service (MBS) service area to a first service area, and the MBS service area is a service area of a service;
- receive second information from the first network capability exposure function network element, wherein the second information indicates that update of the MBS service area fails;
- and
- send third information based on the second information, wherein the third information comprises information about the first service area, and the third information is for triggering establishing a multicast/broadcast session for the service.
A computer-readable storage medium, wherein the computer-readable storage medium comprises a computer program or instructions, and when the computer program or the instructions are run on a computer, the computer is caused to:
- send first information to a first network capability exposure function network element, wherein the first information is for requesting to update a multicast/broadcast service (MBS) service area to a first service area, and the MBS service area is a service area of a service;
- receive second information from the first network capability exposure function network element, wherein the second information indicates that update of the MBS service area fails;
- and
- send third information based on the second information, wherein the third information comprises information about the first service area, and the third information is for triggering establishing a multicast/broadcast session for the service.
