MOBILE NETWORK SWITCHING METHOD AND COMMUNICATION DEVICE
FIG10 is a schematic block diagram of a terminal device according to an embodiment of this application  FIG9 is a schematic block diagram of still another network device according to an embodiment of this application
FIG10 is a schematic block diagram of a terminal device 1000 according to an embodiment of this application. Modules in the terminal device 1000 are separately configured to perform actions or processing processes performed by the terminal device in the foregoing method. Herein, to avoid a repeated description, refer to the descriptions in the foregoing for detailed descriptions.  FIG9 is a schematic block diagram of a communications apparatus 900 according to an embodiment of this application. The communications apparatus 900 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 900 may include a receiving module 901, a processing module 902, and a sending module 903. The processing module 902 is separately connected to the receiving module 901 and the sending module 903. Modules or units in the communications device 900 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.']
