Problems solved by technology

[0004] However, the NSSAI of the network slice supported by the AMF may not include an S-NSSAI in the NSSAI carried when the terminal initiates the registration process, that is, the AMF entity may not support the network slice corresponding to the service
At this time, there is currently no relevant solution for how to make the terminal successfully establish a corresponding business session

Abstract

The embodiment of the invention provides a service session establishment method, equipment and a system, which can enable a terminal to successfully establish a corresponding service session when a current AMF (Access and Mobility Management Function) entity may not support a network slice corresponding to a service. In order to achieve the above purpose, the embodiment of the invention provides the following technical scheme: receiving network slice information from a first AMF entity by the terminal when the terminal is registered to a service network through the first access and mobility management function (AMF) entity; determining a second AMF entity supporting the network slice corresponding to the service by the terminal according to the network slice information; and establishing aservice session of the service by the terminal through the second AMF entity.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a method, device and system for establishing a business session. Background technique [0002] A network slice is a logical network used to support specific network capabilities and network characteristics. It can include the entire network end-to-end (E2E), or part of the network functions can be shared among multiple network slices. It is a key technology to meet the differentiated requirements of the fifth generation (5th generation, 5G) mobile communication technology proposed by the third generation partnership project (3rd generation partnership project, 3GPP) on transmission network differentiation. Usually, the transmission network characteristics of different network slices are different, and the network slices are required to be isolated from each other without affecting each other. For example, network slicing for augmented reality (AR) or virtual ...
