Embodiment Construction

[0047] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0048] Embodiments of the present application provide a session management method and a method for interoperability of different systems, and the method is applied to an interoperability framework of different systems. The heterogeneous system specifically refers to two different communication systems, such as 5G network and 4G network. Of course, it can also be other communication systems, such as New Radio (NR) system, wireless fidelity (wifi), global microwave Internet Access (Worldwide Interoperability for Microwave Access, WiMAX), Global System of Mobile Communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (Wideband Code Division Multiple Access) , WCDMA) system, general packet radio service (General Packet Radi...

Abstract

Embodiments of the present application provide a session management method, a method for interoperability between different systems, and a network device. The session management method includes: when establishing a guaranteed bit rate GBR stream of a terminal device in a first communication system, the first The session management network element in the communication system determines that the GBR flow is the GBR flow required by the terminal device to switch from the first communication system to the second communication system; the session management network element establishes a connection with the GBR flow for the GBR flow The session context corresponding to the second communication system. The technical problem of resource waste exists in the handover method used to solve the prior art.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a session management method, a method for interoperability among different systems, and a network device. Background technique [0002] In the fifth generation mobile communication technology (5th generation, 5G) network, in order to ensure the communication between the 5G network and the fourth generation mobile communication technology (4th Generation, 4G) network or other networks (for example: the second generation mobile communication technology (2thGeneration , 2G) network or third-generation mobile communication technology (3th Generation, 3G) network) interoperability, using an interworking process similar to that between 4G and 3G or 4G and 2G networks, for example: using mobility management (Mobility Management, MM) context mapping or session management (Session Management, SM) context mapping to switch. [0003] However, there is a problem...
