Abstract

The invention discloses a redirection allocation method, device and system. The method includes: responding to the redirection request of the access and mobility management function network element AMF currently connected to the terminal, obtaining the identification information of the current AMF and the identification information of the target AMF from the redirection request; redirecting the terminal from the current AMF to The interface AMF in the first AMF set, and the terminal jumps to the interface AMF in the second AMF set from the interface AMF in the first AMF set; The terminal is redirected to the target AMF from the interface AMF in the second AMF set, Obtain the redirection path from the terminal to the target AMF. According to the method, the problem of AMF redirection failure of the terminal device caused by the security isolation degree of the network slicing service can be solved.

Description

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