Abstract: This disclosure provides methods, apparatuses, and a system for implementing service continuity in a data flow switch procedure. One example method includes that indication information is used to indicate a data flow for which an end marker message is used. In the data flow switch procedure, after receiving the end marker message, a source access network device can correctly identify, based on the indication information, the data flow on which the end marker message works, and can perform different processing on a data flow switched to a target access network device and a data flow kept on the source access network device.

Abstract: A data processing method and a data processing apparatus are described that simplify an operation procedure in which an access and mobility management function (AMF) entity delivers a quality of service (QoS) parameter to an access network device to which the terminal device requests to connect or a target access network device to which the terminal device requests to be handed over, and reduce signaling overheads. The described method includes an access and mobility management function AMF entity receiving a quality of service QoS parameter used for a ProSe communication 5 (PC5) interface communication of a terminal device. The AMF entity stores the QoS parameter. When a preset condition is satisfied, the AMF entity sends the stored QoS parameter to a first access network device.

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.
