Abstract: A communication method and an apparatus are provided, so that a terminal device can flexibly perform a handover procedure in a multicast service scenario. The method includes: sending, by a source access device, a first message to an access controller, where the first message is used to request to hand over a terminal device to a target access device, and the first message includes a multicast service context of the terminal device; and receiving, by the source access device, a fifth message from the access controller, wherein the fifth message is used to respond to the message used to request to hand over the terminal device to the target access device, and the fifth message comprises indication information indicating whether to forward multicast service data.

Abstract: A configuration serving network element may configure information about the configuration serving network element for a fifth generation (5G) network architecture. A terminal device may obtain the information about the configuration serving network element from the 5G network architecture. The information about the configuration serving network element includes address information of the configuration serving network element. Therefore, the terminal device can establish a connection to the configuration serving network element based on the address information of the configuration serving network element, so that the configuration serving network element can automatically configure the terminal device by using the 5G network architecture.

Abstract: In a connection reactivation method, a connection of a PDU session established by user equipment on a N3GPP side is reactivated through communications via a 3GPP network. The user equipment accesses both the 3GPP and the N3GPP network and is originally in an idle state on the N3GPP network. An access and mobility management function entity receives a first message from a session management function entity to reactivate the PDU session connection of the user equipment. The access and mobility management function entity sends a second message to the user equipment via the 3GPP access network to instruct the user equipment to reactivate the connection of the PDU session.
