Description
Technical field
The present invention relates to the mobile communication technology field, particularly a kind of method that user terminal (UE) is carried out identification.
Background technology
Along with the continuous development of mobile communication technology, mobile communication system also should be supported ecommerce, E-Payment, stock exchange, Internet service etc. except traditional voice, data, multimedia service are provided.Along with the continuous expansion of mobile communication business, the safety of network and transmission information will become the matter of utmost importance of its development of restriction.The safety problem that mobile communication system faces mainly comprises: utilize the weakness of procotol and system, unauthorized access sensitive data, unauthorized processing sensitive data, interference or the service of abuse network or the like.
Third generation partner program (3GPP) has been worked out a whole set of safety precaution mechanism, to guarantee the fail safe of mobile communications network and institute's information transmitted.The third generation that 3GPP formulated (3G) network security logical construction is divided into five classes at different attack types, i.e. network access security, core net safety, user security, application safety, security feature observability and configurable ability.
It is the important means of guaranteeing network access security that UE is carried out identification, and its core content is: the network element of network side is discerned the identity of UE by the international mobile subscriber identity (IMSI) that obtains the user.
TS 24.008 that 3GPP formulates and TS 29.002 have defined the flow process of UE being carried out identification by mobile switching centre (MSC) initiation, comprise two sub-processes, be that MAP gets identification (Map SendIdentification, MSI) flow process and identification request (Identity Request) flow process, wherein the fail safe of MSI flow process is higher, therefore preferentially obtain IMSI generally speaking,, just obtain IMSI by the identification flow process if this flow process can not get access to IMSI by the MSI flow process.The flow process of being initiated by MSC that UE is carried out identification comprises the steps: as shown in Figure 1
Step 101:UE carries out the location registers flow process at a MSC, after the success, the VLR Visitor Location Register of the one MSC correspondence (VLR1) has the user data of UE, comprising IMSI, if VLR1 initiates the TMSI allocation flow, the TMSI that then comprises UE in the user data, and UE can receive temporary mobile station identification code (TMSI) that a MSC is distributed and corresponding lane place identification (LAI) information.
Step 102:UE roams into the zone of the 2nd MSC, and UE sends position register request to the 2nd MSC, and (Location Updating Request LUR), has carried TMSI and old LAI that a MSC is distributed, i.e. the LAI of a MSC correspondence in LUR.
Step 103: if described LAI is adjacent with the 2nd MSC, the 2nd MSC initiates the MSI flow process according to TMSI that is received and LAI, obtains the information such as IMSI of UE to a VLR place, and starts flow process protection startup timer T1; If described LAI and the 2nd MSC are non-conterminous, then irrelevant with content of the present invention, according to the flow processing of existing protocol regulation.
Step 104: the 2nd MSC judges whether to get the identification response overtime whether the receiving of T1, if receive response, then go to step 108; If do not get the identification response up to overtime the returning of timer T1, then execution in step 105; Wherein, the flow process protection timer T1 of the MSI of 3GPP TS 29.002 regulations is s, and the time of s is 3～10 seconds.
Step 105: the 2nd MSC initiates the identification flow process and sends identification message and start flow process protection timer T2 to UE.
Step 106: the 2nd MSC judges whether to receive the IMSI from UE before timer T2 is overtime; If then go to step 108; Otherwise execution in step 107.The identification timer T2 of 3GPP TS 24.008 regulations is T3270, and the time is 12 seconds.
Step 107: the 2nd MSC continues the follow-up flow process of executing location registration failure, process ends then after finishing.
Step 108: stop corresponding flow process protection timer T1 or T2 and carry out steps such as the follow-up authentication of identification, encryption, enter flow process after finishing in the location registers at the 2nd MSC place.
For general packet radio service (GPRS) system, 3GPP TS 23060 has defined the flow process of UE being carried out identification by Serving GPRS Support Node (SGSN) initiation, this flow process also comprises two sub-processes, be respectively to identity authentication request (Identification Request) sub-process of original SGSN initiation and the identification request sub-process of initiating to UE, and previous sub-process priority is higher.As shown in Figure 2, this flow process comprises the steps:
Step 201:UE carries out the location registers flow process at a SGSN, after the success, the one SGSN and UE have IMSI, grouping temporary mobile subscriber identity (P-TMSI), Routing Area Identifier (RAI) and the P-TMSI signature (P-TMSI signature) of UE, for convenience of description, above three is called as old P-TMSI, old RAI and old P-TMSI signature respectively.
Step 202:UE roams in the 2nd SGSN scope, and (Attach Request AR), comprises old RAI, old P-TMSI and old P-TMSI signature among the AR to adhere to request to the 2nd SGSN transmission user.
Step 203: the 2nd SGSN finds a SGSN according to old RAI among the receiving AR and old P-TMSI, and sends the identity authentication request to a SGSN, comprises old RAI, old P-TMSI, old P-TMSI signature in this request, starts timer T1 simultaneously; Stipulate among the 3GPP TS 24008 that this flow process protection timer T1 is T3370, duration is 6 seconds.
Step 204: the 2nd SGSN judges whether to receive the identity authentication response message from a SGSN before T1 is overtime, if then execution in step 208, otherwise execution in step 205.
Step 205: the 2nd SGSN sends the identification request and starts timer T2 to UE, and 3GPPTS 24.008 regulation T2 are T3270, and duration is 12 seconds.
Step 206: the 2nd SGSN judges whether to receive the identification response message from UE before T2 is overtime, if execution in step 208 then, otherwise execution in step 207.
Step 207: the 2nd SGSN continues the follow-up flow process of executing location registration failure, process ends after finishing.
Step 208: the 2nd SGSN stops corresponding flow process protection timer T1 or T2 and carries out steps such as the follow-up authentication of identification, encryption, enters the flow process of UE in the location registers of the 2nd SGSN after finishing.
In the flow process of above-mentioned two kinds of identifications, all to carry out first sub-process earlier, after the timer T1 of first sub-process is overtime, just start second sub-process.For example, for first kind of identification flow process, to initiate MAP earlier and get identification process, if this flow process does not obtain response, to wait until that then the timer T1 of MSI flow process just continues to initiate the identification flow process after overtime, may cause obtaining the required overlong time of IMSI like this, the time of timer T1 is 3～10 seconds, the time of timer T2 is 12 seconds, if just obtain IMSI in the identification flow process, then the time that is spent may reach tens seconds.In like manner, the problem of the required overlong time of IMSI also can appear obtaining in second kind of identification flow process.Therefore can cause following problem:
The time of the location registers timer T3210 of 3GPP TS 24.008 regulation is 20 seconds, if obtain the required overlong time of IMSI, the time of then leaving location registers flow process subsequent step for and causes the possibility of location registers failure to increase very little; Period of reservation of number is oversize simultaneously, to the satisfaction decline of the business that operator provided.
Summary of the invention
In view of this, the objective of the invention is to, propose a kind of method that UE is carried out identification, can shorten and obtain the time that IMSI spends.
This method comprises first sub-process and second sub-process that is used for identification, and wherein the first sub-process priority is higher than second sub-process, and the timer T3 of a duration less than first sub-process protection timer T1 duration is set, and this method comprises the steps:
A, user terminal move to the second network element zone from the first network element zone, and second network element is initiated first sub-process to first network element, and start timer T1 and timer T3 simultaneously;
Whether B, judgement receive the response message of first sub-process before timer T3 is overtime, if, then stop timer T1 and T3, finish the follow-up processing flow of first sub-process and existing identification flow process and withdraw from this flow process; Otherwise when continuing first sub-process, second network element is initiated second sub-process to user terminal.
Step B judges the response message of not receiving first sub-process, further comprises after step B:
The protection timer T2 of C, startup second sub-process;
In D,, a period of time that timer T1 is not overtime overtime at timer T3, if second network element is received the response message of arbitrary sub-process, then stop timer T1 and T2, finish the sub-process of response message correspondence of receiving and withdraw from another sub-process, have the follow-up flow process of identification flow process after being finished now and withdraw from this flow process; If do not receive any one response message in above-mentioned two sub-processes up to T1 is overtime, then finish first sub-process;
In E,, a period of time that timer T2 is not overtime overtime,, then stop timer T2, finish second sub-process and withdraw from this flow process if second network element is received the response message from second sub-process at timer T1; If up to the overtime response message of not receiving second sub-process of T2, then process ends.
If described first network element and second network element are mobile switching centre;
Then described first sub-process is that the MAP of third generation partner program standard 3GPP TS 24.008 defineds gets identification process, and described second sub-process is the identification flow process of 3GPP TS 29.002 defineds.
The described startup timer of steps A T1 is: the duration of stipulating among the startup 3GPP TS29.002 is 3～10 seconds timer s.
