Abstract: This application discloses example communications methods and apparatuses. One example method includes receiving, by a core network element, a first request message from a terminal, where the first request message is used to request information used for PC5 interface-based communication of the terminal. The core network element can then send, to the terminal and based on the first request message, a quality of service (QoS) rule used for the PC5 interface-based communication.

Abstract: Embodiments of this application disclose a communications method, apparatus, and system. Specifically, after receiving information about a multicast area from a sender of a multicast service, a first core network device in a first network obtains, based on the information, indication information indicates that the first network cannot support the multicast service in the multicast area, or indicates that the first network supports the multicast service in a portion of areas of the multicast area; and sends the indication information to the sender. In this way, the sender of the multicast service can determine whether the first network supports the multicast service in the multicast area.
