Abstract

The invention relates to a method and a device for processing mobility management, the method comprises the following steps: an SMF network element receives a data notification message comprising a PDU session identifier sent by a UPF network element, and a session and service continuity SSC mode corresponding to the PDU session identifier and / or a service area of a user plane function UPF network element can be determined according to the PDU session identifier, the UPF network element is a network element for establishing a PDU session corresponding to the PDU session identifier; the SMF network element determines a paging area according to the SSC mode and / or a service area of a UPF network element; and the SMF network element sends a first message including the paging area to an access and mobility management function (AMF) network element, wherein the first message is used for triggering the AMF network element to page a terminal which establishes the PDU session through the UPF network element in the paging area.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a processing method and device for mobility management. Background technique [0002] In the next-generation wireless communication system, for example: in the new radio (New Radio, NR) system, the terminal establishes protocol data with the data network (Data Network, DN) network element through the user plane function (User Plane Function, UPF) network element Unit (Protocol Data Unit, PDU) session, the PDU session provides the PDU connection service between the terminal and the DN network element. [0003] The PDU session has three session and service continuity (Session and Service Continuity, SSC) modes (Mode), respectively: SSC mode 1, SSC mode 2, and SSC mode 3. [0004] SSC mode 1: In this mode, after the terminal establishes a PDU session, no matter where the terminal moves to any area or under any access technology, the UPF network element of the...
