Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.But embodiments of the present invention are not limited thereto.
In each embodiment of the present invention, IMEI function is reported by opening SGSN, this field is carried in the CDR ticket of CG, connect CG in real time by the server arranged and take ticket away, read MSISDN wherein, IMSI, IMEI, userLocationInformation(geo-location parameter), recordOpeningTime, ChangeTime(ticket change the time) etc. key parameter, by setup times thresholding, if find that same IMSI user has multiple different I MEI, and at one time or the record having diverse geographic location to activate in very short time, then identifying this user is the user having copy card suspicion, output report simultaneously.
First the program sets up a set of server, by connecting all CG, read the key parameters such as MSISDN, IMSI, IMEI, userLocationInformation, recordOpeningTime, ChangeTime of every part of CDR ticket, then contrast, by arranging analysis rule, if find the corresponding different IMEI of same IMSI, and at one time or the short time activate at diverse geographic location, then this number is identified, feed back and also notify related personnel in time in form.
During concrete enforcement, user can be determined by MSISDN, IMSI; The terminal that user uses can be determined by IMEI; Ticket generation time recordOpeningTime, ticket change time ChangeTime parameter determination time threshold can be passed through; After obtaining geographical location information, can judge in two places whether be abnormal according to time threshold.
As shown in Figure 1, be the mobile communication copy card defining method principle flow chart that the embodiment of the present invention 1 provides, specific as follows:
Step 11, determines the international mobile device identification IMEI that international mobile subscriber identification IMSI exists.
IMSI is the mark of mobile subscriber, and IMEI is the mark of mobile terminal, and normal users has the corresponding IMEI of an IMSI.First need to be confirmed whether that IMSI exists IMEI, and set up corresponding relation.
Step 12, if IMEI number is greater than 1, and each IMEI activates in different geographical position, determines that IMSI exists copy card.
If find that same IMSI user has multiple different I MEI, then can illustrate that the SIM card of same user is used on multiple mobile terminal, be likely so just the problem of copy card.Further, need to determine whether these multiple IMEI activate in different geographical position, if so, then illustrate that multiple IMEI that this IMSI is corresponding use in different geographical position, thus, can confirm that this IMSI exists copy card.Namely there is multiple mobile terminal in same user, and activate use at diverse geographic location, can illustrate that this user exists multiple SIM card, namely copy card.
As shown in Figure 2, be the mobile communication copy card defining method principle flow chart that the embodiment of the present invention 2 provides, specific as follows:
Step 21, the CDR ticket according to user obtains MSISDN, IMSI, IMEI, recordOpeningTime, ChangeTime parameter and geographical location information.
Here IMSI is the mark of difference mobile subscriber, is stored in SIM card, can be used for the effective information distinguishing mobile subscriber.IMEI is the abbreviation of International Mobile Equipment Identity code, international mobile equipment identification code, is made up of " electronics string number " 15 bit digital, it and every platform mobile phone one_to_one corresponding, and this yard is that the whole world is unique.Each mobile phone all will be endowed a globally unique sets of numbers after finishing assembly, and this number is delivered for use all by institute of the manufacturer of manufactured production record from producing to.
MSISDN refers to that calling subscriber is the required number dialled of a mobile subscriber in calling GSM PLMN, and effect is same as fixed network PSTN number; Be in the numbering plan of public telephone network switching network, uniquely can identify the number of mobile subscriber.
CDR is GSN charging bill, is produced and deliver to charging center in order to charging by GSN.CDR can be G-CDR(GGSN ticket), also can be S-CDR(SGSN ticket).
SGSNAddress is SGSN address, is used for identifying the GTP(GPRS Tunneling Protocol of SGSN, GPRS Tunnel Protocol in charging bill) address.
UserLocationInformation is customer position information parameter, in order to state user position residing at present, is important user identification parameter, carries the userLocationInformation parameter of positional information LAC/CI/TAI/TAC.Can determine to the particular geographic location information of user according to userLocationInformation.
RecordOpeningTime is ticket generation time, is used for record PDP(Packet DataProtocol, packet data protocol) activate and produce time of ticket.
ChangeTime is that ticket changes the time.
Specifically, in the present embodiment, IMEI function is reported by opening SGSN, this field is carried in the CDR ticket of CG, connect CG in real time by the server arranged and take ticket away, reading the key parameters such as MSISDN, IMSI, IMEI, SGSNAddress, userLocationInformation, recordOpeningTime, ChangeTime wherein.And determine according to parameters such as userLocationInformation, SGSNAddress the geographical location information that user is concrete.Contain in userLocationInformation parameter real LAC/CI/TAI/TAC these directly in order to judge different positions, section communication equipment may be also had positional information not to be put into inside this parameter, therefore the particular geographic location of user is confirmed by geographical location information, these parameters and then comprise these occurrences of LAC/CI/TAI/TAC.
Especially, user's geographical location information obviously also can obtain according to other mode, such as GPS location etc., and the present embodiment does not limit this.
Step 22, according to IMSI, IMEI parameter, judges whether to there is the corresponding multiple IMEI parameter of identical IMSI parameter, if so, performs step 23; Otherwise, return and perform step 21.
Here, because IMSI is the mark of mobile subscriber, and IMEI is the mark of mobile terminal, if find that same IMSI user has multiple different I MEI, then can illustrate that the SIM card of same user is used on multiple mobile terminal, be likely so just the problem of copy card, thus needing to judge whether further is copy card, if do not occur that same IMSI user has the situation of multiple different I MEI, then do not need further judgement, return step 21 and again obtain user's ticket.

UserLocationInformation is the important parameter for position judgment.In fact location-based judgement, can be judged by the different SGSN of the different districts and cities of management, also can be judged by the position information item in ticket, as CI etc.Thus, need to adopt the address information in ticket to judge, be presented as that SGSNAddress, LAC/CI/TAI/TAC etc. are in order to judge the online place that user is concrete further.
The present embodiment can adopt userLocationInformation to judge whether user activates at diverse geographic location, also can adopt SGSNAddress to judge, or, also can determine mode to judge by other concrete geographical position.
The present embodiment judges the mode whether user activates at diverse geographic location, mainly by judging whether user activates at different SGSN.Different SGSN activates, and generally can confirm as different geographical position and activate.Whether certainly, also can obtain user by concrete locate mode and activate in different geographical position, the present embodiment is for concrete acquisition and judge that the mode that user activates geographical position does not limit.
Especially, whether judgement user is activated at diverse geographic location, needs the restriction of a time, normally roam to get rid of user the diverse geographic location activation caused.Thus, need setup times thresholding 1, judge user whether activate at diverse geographic location by within a short period of time according to this time threshold 1.The setting of time threshold 1 can be carried out as required, generally normally roams required time with user and is as the criterion, and needs to get rid of that user normally roams and the diverse geographic location that produces activates.Thus also need to consider concrete distance.If user activates in time threshold 1 on completely non-conterminous two geographical position, then can think that user exists copy card.
According to recordOpeningTime, ChangeTime parameter, step 24, judges that whether user's activationary time is overlapping or close, if so, performs step 25.
Exist after diverse geographic location activates determining user, whether exist according to recordOpeningTime, ChangeTime parameter determination user activated time overlapping or close further.What recordOpeningTime reacted is that user activates and produces the time of ticket, ChangeTime is user's ticket rise time, two parameters accordingly, can obtain whether time that user produces ticket has repetition, namely user whether at one time in generate multiple ticket.If user creates multiple ticket simultaneously, then illustrate that user exists copy card, otherwise, can not determine that user exists copy card, need to judge further.
Step 25, determines that described user exists copy card.
When determining that user exists copy card, can notify user, the use of limited subscriber of also can taking measures in system side, avoids the problem occurring user's rate and use.
If can not determine that user exists copy card, then the card of user can be judged to be suspicious card, determine that user is doubtful and there is copy card, and prompt system or user.
Namely the main innovation of the embodiment of the present invention can find the method for copy card by GPRS network: " report IMEI function by opening SGSN, this field is carried in the CDR ticket of CG, connect CG in real time by the server arranged and take ticket away, read MSISDN wherein, IMSI, IMEI, recordOpeningTime, the key parameters such as ChangeTime, and obtain user's geographical location information, by setup times thresholding, if find that same IMSI user has multiple different I MEI, and at one time or had in very short time diverse geographic location activate record, then identifying this user is the user having copy card suspicion, output report simultaneously.
