Abstract: Embodiments of the present invention disclose a communication method, an access network device, and a core network device. The method includes: sending, by a source access network device, to a core network device a handover message for a handover of one or more sessions of a terminal device from the source access network device to a target access network device, wherein the handover message comprises information about the target access network device and identifier information of the one or more sessions; and sending, by the core network device, a response message of the handover message to the source access network device, wherein the response message of the handover message comprises indication information indicating a reason that a session of the one or more sessions is not accepted, wherein the reason is associated with a slice corresponding to the session.

Abstract: Embodiments provide a duplication transmission method and apparatus. The method includes: receiving, by a terminal device, duplication transmission configuration information sent by a radio access network RAN device, where the duplication transmission configuration information includes configurations of at least one of a duplication transmission mode or duplication transmission content of the terminal device; and performing, by the terminal device, duplication transmission based on the duplication transmission configuration information.

Abstract: This application provides a handover method in a mobile network and a communications apparatus. The method includes: sending, by a target access network node, a path switch request to a first core network node, where the first core network node is an access and mobility management function supported by both a source access network node and the target access network node, and the path switch request includes indication information of at least one semi-accepted flow/session/radio bearer; and receiving, by the target access network node, a path switch request reply sent by the first core network node, where the path switch request reply includes at least one of the following parameters: a flow/session/radio bearer whose path is successfully switched, a flow/session/radio bearer whose path fails to be switched, indication information of a new network slice, or a context of a modified flow/session/radio bearer.
