Abstract

The invention relates to a 4G and 5G network interoperation method and device, a system, equipment and a storage medium. The 4G and 5G network interoperation method is applied to the situation that user equipment (UE) moves from a 4G network to a 5G network, and comprises the following steps: an authentication management function (AMF) obtains first information of the UE from a mobility managemententity (MME), and the first information carries a serving gateway (SGW) address; according to the SGW address, an interface address between the AMF and second network equipment is obtained from the first network equipment, and the second network equipment comprises a session management function SMF and an SGW which are arranged in a combined mode; and connecting with the SMF of the second networkequipment according to the interface address between the AMF and the second network equipment.

Description

technical field [0001] The present disclosure relates to the technical field of mobile communication, and in particular to a method, device, system, equipment and storage medium for interoperability between 4G and 5G networks. Background technique [0002] In the process of interoperability between 4G and 5G networks in related technologies, there are many handover delays and routing circuitousness, which not only reduces user experience, but also increases network deployment investment. This problem is especially noticeable in roaming situations. Contents of the invention [0003] The present disclosure provides a method, device, system, equipment and storage medium for interoperability between 4G and 5G networks. [0004] According to one aspect of the present disclosure, a method for interoperability between 4G and 5G networks is provided, which is applied to a situation where a UE (User Equipment, user equipment) moves from a 4G network to a 5G network, and the method...
