Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of improving and utilize CallHistoryCount to carry out the implementation method and the device of terminal authentication.
Background technology
CDMA (Code Division Multiple Access, code division multiple access) is a kind of brand-new and ripe wireless communication technology that grows up on the digital spread spectrum communication infrastructure.Because it has unique advantages such as power system capacity is big, speech quality is good, the networking cost is low, message transmission rate height, cdma system has obtained application more and more widely.CDMA terminal commonly used comprises: CDMA mobile phone, cdma wireless landline telephone, CDMA onboard wireless phone, CDMA on-vehicle positioning terminal, cdma wireless data terminal, CDMA multi-user radio landline telephone and CDMA high-power wireless landline telephone etc.
In order to prevent to have no right the safety that subscriber access system communicates by letter with the mobile subscriber who guarantees by wave point, authentication techniques is widely used in the communication network.Also taked special safety measure in cdma system, for example subscription authentication, the speech on the wave point, data and signal message are maintained secrecy etc.The purpose of these safety measures is to guarantee that the safety of user resources and protection user privacy communication's right are inviolable.
And use in the terminal of cdma system at all, one of the largest source that the private privacy of user is caused infringement is clone's mobile phone and clone SIM (Subscriber identification Module, subscriber identification module) card, its ESN (Electronic Serial Number, electronics string number)/IMSI (InternationalMobile Station Identify, international mobile station identity number) etc. identity code is with real handset, truly the ESN/IMSI of SIM card is just the same, the AKEY (Authentication Key, authentication password) of part is also just the same.
At present, the CallHistoryCount authentication can realize the measuring ability to illegal CDMA terminal (as clone's mobile phone and clone SIM card etc.) as an important component part of cdma system authentication.CallHistoryCount is the call meter of agreement regulation, an initial CallHistoryCount is arranged in the user terminal when opening an account, simultaneously at HLR (Home Location Register, Home Location Register) in, also specify an identical CallHistoryCount among the AC (Authentication Centre, AUC).In calling out access procedure, also can preserve the current CallHistoryCount of user terminal (when public enciphered data is shared, preserve, otherwise in AC, preserve) among the VLR (Visitor Location Register, VLR Visitor Location Register) at VLR.Simultaneously, in calling out access procedure, network side AC/VLR also can be as required by COUNT more new technological process refresh CallHistoryCount on the user terminal, for example each location registers or make the CallHistoryCount on the user terminal add 1 when calling out.
When sending to insert, user terminal can carry the inner CallHistoryCount that preserves of user terminal when asking at every turn, whether consistent during the network side authentication with the CallHistoryCount of AC/VLR preservation according to the CallHistoryCount that judges user terminal to send up, if unanimity then think authentication success, otherwise think failed authentication.
Because the identity code such as IMSI/ESN/AKEY in the user terminal all are fixedly to write deadly, illegal terminal (as cloning mobile phone etc.) is just can't be detected by network side after duplicating fully.But CallHistoryCount is a variable value of preserving at user terminal, illegal terminals such as clone's mobile phone can't duplicate, even also can't guarantee after duplicating to upgrade synchronously,, CallHistoryCount can effectively solve illegal terminal problems such as clone's mobile phone so participating in authentication with network side.
Yet also there is defective in the existing technology of utilizing CallHistoryCount to participate in authentication work, with this modal user terminal of mobile phone is example, in the user mobile phone calling procedure, network side is CallHistoryCount in the new cell-phone more all at any time, and some abnormal conditions may cause the inconsistent of the CallHistoryCount that preserves in the mobile phone and network side.For example: mobile phone has been received A interface parameters update request and the CallHistoryCount that self preserves has been added 1, reported normal response, but because the signaling link failure of network side has caused AC/VLR not receive the parameter update response that mobile phone reports, what will cause that the CallHistoryCount of network side and mobile phone preserve is inconsistent.Just relate to the problem that CallHistoryCount recovers in this case.If network side simply upgrades with the CallHistoryCount that mobile phone reports, real handset can't insert in the time of can causing cloning the mobile phone access, thereby makes the authentication functions of CallHistoryCount lose meaning.
