FIG7 is a schematic block diagram of a communications apparatus 700 according to an embodiment of this application. The communications apparatus 700 may be corresponding to (for example, may be configured on or may be) the target RAN node described in the foregoing method 200 or the target RAN node described in the foregoing method 300. The communications apparatus 700 may include a receiving module 701, a processing module 702, and a sending module 703. The processing module 702 is separately connected to the receiving module 701 and the sending module 703. Modules or units in the communications device 700 are respectively configured to perform each action or processing process performed by the target RAN node in the method 200 or the target RAN node in the method 300. To avoid repetition, detailed descriptions thereof are omitted herein.  FIG8 is a schematic block diagram of a communications apparatus 800 according to an embodiment of this application. The communications apparatus 800 may be corresponding to (for example, may be configured on or may be) the first CN node (or also referred to as an AMF node) described in the foregoing method 200 or the AMF node described in the foregoing method 300. The communications apparatus 800 may include a processor 801 and a transceiver 802, and the processor 801 and the transceiver 802 have a communication connection. Optionally, the communications apparatus 800 further includes a memory 803, and the memory 803 and the processor 801 have a communication connection. Optionally, the processor 801, the memory 803, and the transceiver 802 may have communication connections. The memory 803 may be configured to store an instruction. The processor 801 is configured to execute the instruction stored in the memory 803, to control the transceiver 802 to send information or a signal. The processor 801 and the transceiver 802 are respectively configured to perform each action or processing process performed by the first CN node (or also referred to as the AMF node) in the method 200 or the AMF node in the method 300. To avoid repetition, detailed descriptions thereof are omitted herein.

['16. A communications apparatus, comprising: a sending module, configured to send a handover request to a target access network node, wherein the handover request comprises at least one of the following parameters: a context of at least one flow/session, a context of at least one radio bearer, network slice indication information of at least one network slice, and network slice remapping policy information; a processing module, configured to configure content of the handover request; and a receiving module, configured to receive a handover request reply sent by the target access network node, wherein the handover request reply comprises at least one of the following parameters: a  configuration of at least one radio bearer accepted, modified, or newly established by the target access network node, a mapping relationship between the at least one flow/session and the at least one radio bearer, and network slice indication information of at least one new network slice.']
