Abstract

The embodiment of the invention provides a network switching method, a convergence network element, a communication system and a storage medium, and belongs to the field of mobile communication. The method comprises: according to a session context request, performing a first PFCP session update with a user plane convergence network element to initiate a network switching process, so that a user equipment is switched between a 4G session and a 5G session, the user plane fusion network element is a network element obtained by fusing a service gateway user plane network element and an intermediate user plane network element in the core network. According to the technical scheme of the embodiment of the invention, the PFCP session is updated according to the session context request and the user plane convergence network element, so that the interaction process can be reduced, the network switching efficiency is improved, and the session and service continuity is ensured.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a network switching method, a fusion network element, a communication system and a storage medium. Background technique [0002] With the rapid development of 5G communication technology, more and more users have begun to use 5G networks. During use, when the 5G network signal cannot cover the range of the user equipment, the user equipment will switch from the 5G network to the 4G network; and when the 5G network signal resumes covering the user equipment, the user equipment will switch from the 4G network to the 5G network . Therefore, it is necessary to provide a 4G / 5G network switching solution. [0003] Existing 4G / 5G network switching solutions generally add SGW-U (Serving Gateway User plane function, serving gateway user plane network element), SGW-C (Serving Gateway Control plane function, serving gateway control plane network element) and SMF ( Session Mana...
