FIG6 is a schematic block diagram of a communications apparatus 600 according to an embodiment of this application. The communications apparatus 600 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 600 may include a processor 601 and a transceiver 602, and the processor 601 and the transceiver 602 have a communication connection. Optionally, the communications apparatus 600 further includes a memory 603, and the memory 603 and the processor 601 have a communication connection. Optionally, the processor 601, the memory 603, and the transceiver 602 may have communication connections. The memory 603 may be configured to store an instruction. The processor 601 is configured to execute the instruction stored in the memory 603, to control the transceiver 602 to send information or a signal. The processor 601 and the transceiver 602 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.  FIG5 is a schematic block diagram of a communications apparatus 500 according to an embodiment of this application. The communications apparatus 500 may be corresponding to (for example, may be configured on or may be) the source RAN node described in the foregoing method 200 or the source RAN node described in the foregoing method 300. The communications apparatus 500 may include a receiving module 501, a processing module 502, and a sending module 503. The processing module 502 is separately connected to the receiving module 501 and the sending module 503. Modules or units in the communications device 500 are respectively configured to perform each action or processing process performed by the source RAN node in the method 200 or the source RAN 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.']
