Kind Code:
A1
Abstract:
Disclosed in the embodiment of the present application are a session management method and device and a system, which can maintain service continuity after the terminal is switched from 4G network to 5G network. The method comprises: a mobile management network element receives an identification of packet data network (PDN) connection from the terminal and single-network slice selective auxiliary information (S-NSSAI) corresponding to the identification of PDN connection; and the mobile management network element triggers, according to the identification of PDN connection and the S-NSSAI, a target control plane functional network element to update the user plane path of a packet data unit (PDU) session corresponding to the PDN connection.
