Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0031] An embodiment of the present invention provides an authentication weight synchronization method, such as figure 1 As shown, the method includes:

[0032]101. When the CS domain authentication synchronization fails, in the CSFB scenario, the AuC generates SEQnet according to the value of the current GLC counter, and sends a resynchronization reply to the MSC, and the resynchronization reply carries SEQnet.

[0033] AuC generates SEQnet based on...

Abstract

The invention discloses authentication resynchronization method and device, relates to the technical field of communication, and aims at solving the problem of failure of authentication resynchronization of CS (Circuit Switch) domain under a CSFB scene and enabling UE to be normally connected to the network. The authentication resynchronization method comprises the following steps: generating a serial number array value SEQnet by an authentication center AuC according to the value of the current GLC counter under the CSFB (Switched Switched Fallback) scene after authentication resynchronization of the CS domain is failed; sending the resynchronization response to the MSC, wherein the resynchronization response includes the SEQnet; forwarding the resynchronization response to the UE by the MSC; performing authentication through the UE according to the SEQnet in the resynchronization response. According to the technical scheme, the method is mainly applied to the network authentication of a terminal.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an authentication weight synchronization method and device. Background technique [0002] At present, in the GSM (Global System For Mobile Communications, Global System for Mobile Communications) network, only the network needs to authenticate the terminal, while LTE (Long Term Evolution, Long Term Evolution) / WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access, Address) network authentication introduces the concept of two-way authentication. On the one hand, the network authenticates the terminal to confirm the legitimacy of the terminal, and on the other hand, the terminal also authenticates the network to confirm the legitimacy of the network. The process of the terminal authenticating the network includes comparing the SEQ (Sequence, serial number array value) in the authentication request message with the SEQ stored in the USIM...
