Abstract: Embodiments of this application relate to a communication method and an apparatus. The method includes: A CCF network element first sends reference information of an application to a first network element. Therefore, the first network element determines network slice information corresponding to the application; and then the first network element sends the determined network slice information to the CCF network element. In this way, the CCF network element may determine the network slice information corresponding to the application, so that when an API invoker network element searches for an API, the CCF network element can accurately find, based on an API inquiry parameter, the API from a network slice corresponding to the network slice information.

Abstract: The present disclosure relates to communication methods and apparatus. One example method includes receiving, by a target service entity, a first request message from a first participating service entity, and sending, by the target service entity, a first response message to the first participating service entity. The first request message comprises an identity of a target multicast bearer and a group identity of a terminal group. The first response message is used to instruct the first participating service entity to use the target multicast bearer to send service data of the terminal group.

Abstract: The present disclosure relates to broadcast bearer management methods and devices. One example method includes receiving, by a first bearer management server (BMS), a first message sent by a server, where the first message includes a group identifier of a service group, determining, by the first BMS, a first broadcast bearer for the service group based on the first message, and sending, by the first BMS, a second message to the server, where the second message carries user plane information of the first broadcast bearer.
