1. A method, comprising:
obtaining, by a control plane function entity, a correspondence between address information of one or more user plane function entities and user plane capabilities supported by the one or more user plane function entities, wherein the control plane function entity comprises a broadcast multicast service center control plane function entity or a multimedia broadcast multicast system gateway control plane function entity;
sending, by an application server, a request message to the control plane function entity, wherein the request message requests to establish a session for a first service, the request message comprises service information of the first service, the service information comprises broadcast area information of the first service or service type information of the first service, and the broadcast area information of the first service comprises a cell identity (cell ID) of the first service, a service area identifier (SAI) of the first service, or geographical location information of the first service;
receiving, by the control plane function entity, the request message;
determining, by the control plane function entity, address information of a target user plane function entity based on the correspondence and the service information of the first service; and
establishing, by the control plane function entity, a session connection to the target user plane function entity based on the address information of the target user plane function entity.
