Abstract

The invention discloses a redirection distribution method, a device and a system. The method comprises the following steps: in response to a redirection request of an access and mobility management function (AMF) network element currently connected with a terminal, obtaining identification information of a current AMF and identification information of a target AMF from the redirection request; redirecting the terminal from the current AMF to the interface AMF in the first AMF set, and skipping the terminal from the interface AMF in the first AMF set to the interface AMF in the second AMF set; and redirecting the terminal from the interface AMF in the second AMF set to the target AMF to obtain a redirection path for redirecting the terminal to the target AMF. According to the method, the problem of AMF redirection failure of the terminal equipment caused by the security isolation degree of the network slice service can be solved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a redirection allocation method, device and system. Background technique [0002] In a communication network system, an access and mobility management function network element (Access and Mobility Management Function, AMF) may be responsible for mobility management and access management of the terminal core network. [0003] Due to the security isolation requirements between network slices, when a terminal device needs to connect two network slices at the same time, or wants to switch from one network slice to another network slice, due to the different security isolation degrees of network slice services, when the terminal device wants to When two slice services with different isolation degrees are accessed at the same time, AMF redirection may fail, that is, it is impossible to quickly jump from the AMF corresponding to the current slice to the target AMF ...
