Abstract

Embodiments of the present application provide a session establishment method, device, and system, which can solve the problem in the prior art that NAS messaging cannot be separated from session user plane establishment, which limits application in certain scenarios. The method includes: the terminal sends a first non-access stratum NAS message to a first access network device corresponding to the first access technology, and the first NAS message is used to request session establishment; the terminal receives a message from the first access network device The second NAS message, the second NAS message carries the identifier of the user plane functional network element; the terminal initiates a communication between the terminal and the user plane functional network element through the second access technology according to the identifier of the user plane functional network element session establishment process.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method, device and system for establishing a session. Background technique [0002] In order to meet the challenges of wireless broadband technology and maintain the leading edge of the 3rd generation partnership project (3GPP) network, the 3GPP standard group formulated the next generation mobile communication system (next generation system) network architecture at the end of 2016, called The fifth generation (5rd generation, 5G) network architecture. This architecture not only supports terminal access to 5G core network (5G core network, 5GC) through 3GPP access technology, but also supports terminal access to 5GC through non-3GPP (non-3GPP) access technology. [0003] At present, the process of terminal access to 5GC can be divided into registration process and session establishment process. Among them, in the registration process, the terminal first e...
