Embodiment Construction

[0064] The embodiment of the present invention mainly includes: adding HLR / AUC identification information into the authentication parameter, sending the authentication parameter carrying the HLR / AUC identification information; receiving the authentication parameter, according to the carried HLR / AUC identification information Determine the HLR / AUC, and perform an authentication process based on the HLR / AUC and the authentication parameters.

[0065] Taking the third-generation mobile communication system as an example, as mentioned above, an authentication error occurs due to the inability to distinguish between the active and standby HLR / AUC, and the reasons are as follows:

[0066] 1. When performing consistency verification and legality verification, due to HLR / AUC switching, the KI for authentication is inconsistent;

[0067] 2. During acceptability verification, due to HLR / AUC switching, the SQNHE for authentication is inconsistent with the SQNMS.

[0068] Consistency ver...

Abstract

The invention discloses a method for judging right, a communication system and a device thereof. The method for judging the right includes the steps: HLR / AUC identification information is added in judging-right parameters and the judging-right parameters which carry the HLR / AUC identification information are transmitted; the judging-right parameters are received; according to the carried HLR / AUC identification information, HLR / AUC is confirmed and the process of judging the right is carried out based on the HLR / AUC and the judging right parameters. The invention can identify the HLR / AUC whichgenerates the judging-right parameters in the process of judging the right and can further use the corresponding judging-right parameters to operate so as to avoid judging-right mistakes.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an authentication method and equipment in a communication system. Background technique [0002] In the existing third generation (3G) mobile communication system, the International Mobile Subscriber Identity Information (IMSI), Authentication Key (KI) and Serial Number (SQNMS) are stored in the Mobile Terminal (MS). The home location register / authentication center (HLR / AUC) on the network side correspondingly stores the IMSI, KI and serial number SQNHE for the mobile terminal for mutual authentication between the mobile terminal and the network. [0003] refer to figure 1 , the existing authentication technology of the 3G communication system mainly includes the following settings and procedures: [0004] 101. HLR / AUC generates a random number (RAND, Random Challenge), generates an expected response (XRES, Expected Response), an encryption key (CK, Cipher Key), and an in...
