Authentication method, related device and system in a wireless communication network

Abstract

An embodiment of the present invention provides an authentication method, a related device, and a system in a wireless communication network. A core network device that stores an unused authentication vector for a user equipment can send a first authentication data request message to the authentication device. , the first authentication data request message is used to request the authentication device to generate an authentication vector for the user equipment, receive a first authentication data response message from the authentication device, and the first authentication data response The message carries the first authentication vector generated by the authentication device for the user equipment, and uses the first authentication vector to initiate an authentication process to the user equipment, ensuring that each CS domain / PS domain authentication , the SEQ contained in the authentication vector is newly generated by the authentication device, even if the PS domain authentication is inserted before the CS domain authentication or the CS domain authentication is inserted before the PS domain authentication, the synchronization can be guaranteed to be successful. The problem of authentication failure caused by synchronization failure in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an authentication method, a related device and a system in a wireless communication network. Background technique [0002] Authentication is a part of mobile network security management, and is used to realize the confidentiality and data integrity of the mobile network. In the current mobile communication network, only valid user equipment (User Equipment, UE) has the right to obtain services, and verifying whether the UE is valid needs to be completed through an authentication process. When the UE initiates a registration request, service request or handover request to the network, the authentication process will be triggered. In the second generation (Second Generation, 2G) network system, authentication is a one-way process, and the network needs to verify the legitimacy of the UE; while in the third generation (Third Generation, 3G) network or Long Term Evolu...
