Abstract: This application relates to the field of communication technologies, and provides a communication method and apparatus. In the method, a multicast session management function network element receives a PCC rule corresponding to a first multicast group from a policy control function network element; obtains, based on the PCC rule, a target multicast QoS parameter corresponding to the first multicast group and used for configuring a QoS parameter corresponding to the first multicast group; and sends the target multicast QoS parameter to an access network device, so that the access network device obtains the target multicast QoS parameter, and configures, based on the target multicast QoS parameter, the QoS parameter corresponding to the first multicast group. In this way, a multicast QoS parameter is configured.

Abstract: This application discloses a communications method and apparatus. An example method includes: receiving, by a RAN node, a first message from an AMF node, where the first message includes specified area related information of a terminal device, and the specified area related information is used to indicate a specified area of the terminal device; and when the RAN node determines, based on the specified area related information and first location information of the terminal device, that the terminal device moves out of the specified area, sending, by the RAN node, the first location information or first indication information to the AMF node or an SMF node, where the first indication information is used to indicate that the terminal device already moves out of the specified area.

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: A session activation method, device, and system, and relate to the field of the communications technologies, to resolve an existing problem of relatively high signaling overheads during PDU session activation. The method includes: receiving, by a control plane node, indication information from an AMF node, where the indication information is used to indicate that the AMF node receives a service request message sent by a terminal device; and sending, by the control plane node, an identifier of a to-be-activated PDU session of the terminal device to an SMF node or the AMF node based on the indication information.

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.
