Abstract: This disclosure provides a communication method, apparatus, and system. The method is performed by a remote terminal, which receives first policy information from a policy control function network element, where the first policy information includes a relay mode corresponding to a first application of the remote terminal, determines a first relay mode based on the first policy information, and transmits data of the first application in the first relay mode to a relay device. In the method, the remote terminal selects a relay mode for individual application and deliver data of the individual application in the selected relay mode such that different relay modes can be applied to different applications. In this way, requirements of different applications are met, and collaboration between different relay modes is enabled.

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.
