摘要： Embodiments of this application provide a multicast communication method and a communication apparatus, so that transmission of data of a multicast service can be implemented using a PDU session established by a terminal device, to improve network element utilization. The method may include: An AF network element sends, to a session management network element, first multicast service indication information indicating a first multicast service. The session management network element sends, based on the first multicast service indication information, multicast service information to an access network device that serves a terminal device. The access network device establishes an association relationship between the terminal device and the first multicast service based on the multicast service information, so that the access network device can send, when receiving data of the first multicast service, the data of the first multicast service to the terminal device using a PDU session. The session management network element further sends forwarding rule information of the first multicast service to a user plane network element, so that the user plane network element sends the data of the first multicast service to the access network device based on the forwarding rule information.

摘要： This application provides a communication method, apparatus, and system. The method includes: A policy control network element receives first information, where the first information is service information or a traffic steering requirement, and the traffic steering requirement includes at least one service function. The policy control network element obtains first traffic steering policy information from a first network element based on the first information, where the first traffic steering policy information includes at least one piece of traffic steering policy information, and the traffic steering policy information is used to indicate network elements corresponding to the at least one service function and a sequence in which service data passes through the network elements corresponding to the at least one service function. Based on the foregoing solution, the policy control network element can dynamically obtain the corresponding traffic steering policy information from the first network element based on the first information, thereby dynamically configuring a traffic steering policy.

摘要： An IP address assignment method and an apparatus are provided, to resolve a problem in the prior art that a control plane network element cannot determine, in an IP address assignment process, a terminal device to which IP address information is to be assigned. In the method, after determining an identifier of a terminal device, a core network control plane network element in a mobile communications network assigns IP address information to the terminal device corresponding to the identifier of the terminal device. In this way, after assigning the IP address information, the core network control plane network element can determine a correspondence between the IP address information and the identifier of the terminal device. Therefore, the core network control plane network element can accurately assign an IP address to the terminal device, and can further perform policy control based on the IP address of the terminal device, so that the terminal device can access an external data network.
