Description

A kind of method and system for verifying international mobile equipment identity in trunking manner

Technical field

The present invention relates to moving communicating field, relate in particular to a kind of method for verifying international mobile equipment identity in trunking manner, equipment identity register and system.

Background technology

In GSM, WCDMA and TD-SCDMA digital mobile cellular telecommunication net, can be by enabling IMEI (International Mobile station Equipment Identity, International Mobile Station Equipment Identification) verification scheme realizes the access to netwoks of mobile device (Mobile Equipment is called for short ME) is controlled.

Owing to enabling at first the object of IMEI verification, be set to prevention faulty equipment and stolen equipment access mobile network, therefore when IMEI is carried out to verification, the equipment state corresponding with IMEI (Equipment Status, be called for short ES) be the whether legal unique foundation of mobile device, conventionally at EIR(Equipment Identity Register, equipment identity register) according to equipment state, complete IMEI verification.

Particularly, EIR comprises one or several for storing the database of IMEI, mainly completes identification to mobile device, monitors the functions such as locking.IMEI can be stored in three, white list, gray list and blacklist independently in list:

● in white list, preserve number section of the device identification of all permissions uses;

● in blacklist, preserve all device identifications that are blocked;

● the not locking of equipment in gray list, but by Network records (in order to add up and other objects).

Equipment state refers to the store status of IMEI in EIR, is respectively: be put into white list, be put into gray list, be put on the blacklist and the unknown.

Its concrete checking procedure is as follows:

From MSC(Mobile-service Switch Center, mobile services switching centre)/SGSN(Serving GPRS Support Node, Serving GPRS Support Node) receive " Check IMEI " message, parse IMEI/TAC(Type Allocation Code, model assigned code), inquiry be take the tables of data (white list, blacklist, gray list etc.) that IMEI/TAC is index and is obtained corresponding with it ES, and using it as IMEI check results, sends it back described MSC/SGSN; Wherein, take the access to netwoks that IMEI verification mode that IMEI is index realized based on mobile device individual cell controls; The access to netwoks that the IMEI verification mode that the TAC of take is index has realized based on mobile device model is controlled.

Obviously, above-mentioned IMEI verification scheme cannot be taken precautions against IMEI itself by bootlegging problem: if certain IMEI is legal, bootlegging the mobile device of this IMEI can be considered to equally legal, and access to mobile network smoothly.

For the above-mentioned IMEI that cannot take precautions against that exists in the IMEI verification scheme solving in standard is by the problem of bootlegging, prior art generally can be chosen in standard " Check IMEI " message increases parameter, as IMSI(International Mobile Subscriber Identity, IMSI International Mobile Subscriber Identity), MSISDN(Mobile Subscriber ISDN, mobile subscriber ISDN number) etc., to increase the accuracy of identification to mobile device.

Therefore, after improving, EIR completes IMEI verification conventionally in the following way:

From MSC/SGSN, receive " Check IMEI " message strengthening, parse the tlv triple <IMEI of mobile device, IMSI, MSISDN> or binary group information <IMSI, the information such as IMEI>; Data query table, determines whether whether described IMEI be the legal user of described IMEI by the mobile subscriber of bootlegging and this IMSI or MSISDN representative; According to the identity validation result to described mobile device and user thereof, and the processing rules of the requirement of the validated user of described mobile device (as whether reported the loss, whether break down etc.) and operator (as forbid or allow bootlegging equipment networking etc.), determine the equipment state that described mobile device is final, and it is sent it back to described MSC/SGSN as IMEI check results;

In above-mentioned IMEI verification mode, what EIR equipment was used is the mobile device list of expansion, adopts IMSI or MSISDN to indicate the validated user of the mobile device that described IMEI is corresponding; If described IMEI is not by bootlegging or used by validated user, using the equipment state in mobile device list as check results, and take as according to this mobile device is carried out to access to netwoks control; If described IMEI, by bootlegging and used by disabled user, carries out access to netwoks control according to the rule of operator to this mobile device.

Can find out, by above-mentioned " Check IMEI " message to standard, strengthen, can make EIR possess the IMEI of strick precaution by the function of bootlegging; Even if existed in a large number the mobile device (Gray Handset, i.e. so-called " mountain vallage machine ") that uses bootlegging IMEI in network, still can enable IMEI verifying function; Like this, by guiding " becoming a full member " process in advance, gradually reduce " mountain vallage machine " in netting index amount, then enable the IMEI verification to " mountain vallage machine ", can eliminate to greatest extent IMEI by bootlegging phenomenon, improve identifiability and the serviceability of mobile device.

While enabling IMEI verifying function in relatively large network, for solving EIR networking problem, generally can be equipped with CEIR(Central Equipment Identity Register, central equipment marker register) equipment; CEIR is higher leveled EIR equipment, stores IMEI central database, and this IMEI central database comprises the information of whole mobile devices in mobile communications network; Concrete, this IMEI central database is distributed mass data storehouse, general storage IMEI and equipment state, also can comprise that other available information is as the time of IMSI, MSISDN, the time of enabling first in network, the last appearance and once in which MSC or SGSN appearance etc.; CEIR equipment has been realized the centralized management of mobile device information, formed server/client relationship with EIR equipment, and the data exchanging function of CEIR equipment IMEI verification needs in meeting net, be also responsible for the shared and exchange of the mobile device list (being mainly blacklist) between different operators.

Thereby the idiographic flow of IMEI verification comprises the following steps:

● MSC/SGSN sends " Check IMEI (IMEI) " message to EIR;

● EIR sends " Remote Check IMEI (IMEI) " message to CEIR, and this message is converted into the remote inquiry to CEIR by local IMEI check request;

● CEIR utilizes inner sign verification unit to carry out verification to this mobile device, to EIR, returns to " Remote Check IMEI Ack (IMEI) " message;

● EIR returns to " Check IMEI Ack (IMEI) " message to MSC/SGSN, and MSC/SGSN determines whether to allow this mobile device to carry out access to netwoks according to received check results.

But introduce after CEIR equipment, EIR equipment need to be stored in the distal end I MEI central database in CEIR with lookup table mode real-time query in checking procedure, so the response time of checking procedure is uncertain, has the defects such as construction cost is high, inefficiency.

For solving the series of problems that in IMEI checking procedure, real-time query distal end I MEI central database brings, can introduce the method for quick verification IMEI, its know-why is: the EIR that carries out IMEI verification is decomposed into ES by IMEI verification and changes identification and ES renewal, in the single IMEI verification for specific mobile device, only carry out one of them stage; Be that EIR ES that identify, specific mobile device in certain IMEI verification changes and will once in the IMEI verification for this specific mobile device, upgrade upper.

For realizing above-mentioned quick verification IMEI method, IMEI central database in CEIR equipment and the data record in the mobile device list in EIR equipment generally all comprise tlv triple and the status information of equipment of mobile device, but every implication difference that data record is represented:

● in CEIR equipment, what the equipment state that data record represents to meet the mobile device of certain condition should be;

● in EIR equipment, data record is annotated " instruction " that will carry out for EIR equipment, and the mobile device that is about to meet certain condition is set to desired equipment state.

The object of IMEI verification is to make MSC/VLR(Visit Location Register, Visited Location Registor) equipment state of mobile device keeps synchronizeing (when MSC carries out mobile device access control with IMEI central database and in SGSN, the information of mobile device is kept in VLR), and realize the access to netwoks of mobile device is controlled according to equipment state; The real process of this quick verification IMEI method is: from VLR/SGSN, send up-to-date tlv triple and status information of equipment to EIR and CEIR; Whether described EIR checks has the equipment state being stored in local mobile device list to upgrade instruction, if had, the equipment state of usining in described renewal instruction is as check results, realize synchronizeing of VLR/SGSN and equipment state in IMEI central database, otherwise, keep current device state constant; By CEIR, identify whether to upgrade the equipment state of mobile device in VLR/SGSN; If needed, CEIR sends to EIR by renewal instruction, and upper, once in the IMEI verification for described mobile device, is handed down to VLR/SGSN by EIR.

In addition,, in quick verification IMEI process, the equipment state renewal instruction being stored in the local mobile device list of EIR equipment can be deleted after execution, to reduce the length of local mobile device list; In checking procedure, EIR only needs the mobile device list of inquiring about local storage can provide check results, and pending operational order negligible amounts in list, therefore can realize the object of quick verification.

Concrete, Fig. 1 shows the flow chart of the method for above-mentioned quick verification IMEI, comprises the following steps:

Step S101, by MSC/SGSN, to EIR, send " Extended Check IMEI " (IMEI check request of expansion) message, this message has been added the current ES of mobile device on the basis of former " Check IMEI " (IMEI verification) message, preferably, can further include the information such as IMSI and MSISDN; And the information such as current ES have been stored among VLR or SGSN, MSC/SGSN can easily obtain;

Step S102, EIR receives and resolves " Extended Check IMEI " request message, according to the mobile device identifying information in analysis result, inquire about local mobile device list, this this locality mobile device list is for recording all instructions that are used for upgrading mobile device status;

If there is the data record matching with this mobile device in this this locality mobile device list, according to list, require final ES is set, otherwise keep current ES constant; If the described record matching with this mobile device only relates to this mobile device, from local mobile device list, delete described record;

EIR resolves the ES obtaining or has to match and according to list, requires set ES while recording when target ES(records without matching) as check results, with the form of " Extended Check IMEI Ack " (IMEI verification response of expansion) message, send to MSC/SGSN, MSC/SGSN determines whether to allow this mobile device to carry out access to netwoks according to received check results;

Step S103, EIR sends " Update ME Info Request " (mobile device information updating request) message to CEIR, sends IMEI, current ES and the possible information relevant with mobile device such as IMSI, MSISDN to CEIR;

Step S104, CEIR receives " Update ME Info Request " message, and the ES information in message and the ES information in IMEI central database are compared, and determines whether upgrade the ES of corresponding IMEI in EIR; If do not needed, do not upgrade, send and represent that normal " Update ME Info Response " (the mobile device information updating response) message receiving is to EIR, otherwise send " the Update ME Info Response " message of instruction comprised for upgrading the list of EIR mobile device to EIR, generally, be using the ES inquiring from IMEI central database and to the identifying information of described mobile device as " the Update ME Info Response " message of encoding of the renewal instruction to described EIR;

Wherein, CEIR utilizes received information to upgrade IMEI central database, as receives the time of IMEI verification message, the source of IMEI verification message and possible IMSI, MSISDN etc.;

After this, EIR receives " Update ME Info Response " message, if comprised in this message for upgrading the instruction of mobile device status, according to command request, is increased newly as a record in described local mobile device list.

Can find out, in the method for quick verification IMEI, the variation of the equipment state identifying will be deferred to when EIR carries out IMEI verification to this mobile device next time to be upgraded, corresponding the delaying of entry-into-force time of check results; Due to the frequency of occurrences of IMEI verification trigger event higher (as position more new events in the frequency of occurrences of busy, can reach once per hour), increase to the delay of check results entry-into-force time generally within acceptable scope.

But, the result of the quick verification of above-mentioned IMEI is only stored in the EIR that carries out this verification, when mobile subscriber leaves after the area of coverage of this EIR, the check results that before produced lost efficacy, when mobile subscriber enters after the area of coverage of another EIR, this another EIR need to re-execute the operation that ES changes identification and ES renewal, and therefore, the entry-into-force time of check results will more extend.

At the EIR area of coverage, less or mobile device is the in the situation that of high-speed moving state, system in check results the performance aspect the entry-into-force time to worsen will be more remarkable.

And in present stage, the market demand to high performance-price ratio IMEI calibration technology is day by day urgent, can the development priority of IMEI calibration technology be to enhance product performance, reducing the construction costs, and carry out substantial improvements to check results entry-into-force time index, be to improve the key of the quick check system cost performance of IMEI.

In addition, MSC/SGSN equipment is general has direct signaling circuit with one to two EIR equipment, and the IMEI check request that a certain MSC/SGSN equipment produces is processed by one to two the EIR equipment of fixing.Practical business that MSC/SGSN equipment is born load there are differences, and may change along with the time, and the response time of each IMEI verification also there are differences, therefore, the traffic handing capacity of EIR equipment certainly exists larger difference.Although can carry out the adjustment of run duration by artificial optimization's mode, often be difficult to the load balancing effect that reaches best.This must cause the utilance of EIR equipment to reduce, and has further strengthened the construction cost of system, and it is best that the indexs such as the reliability of system, availability and extensibility are also difficult to reach.

In sum, to IMEI calibration technology in addition perfect, improve and there are wide market prospects, be also very important.

Embodiment

In the following description, a large amount of concrete details have been provided to more thorough understanding of the invention is provided.Yet, it will be apparent to one skilled in the art that the present invention can be implemented without one or more these details.In other example, for fear of obscuring with the present invention, for technical characterictics more well known in the art, be not described.

Obviously, execution of the present invention is not limited to the specific details that those skilled in the art has the knack of.Preferred embodiment of the present invention is described in detail as follows, yet except these are described in detail, the present invention can also have other execution modes.

According to the present invention, provide a kind of method and system for verifying international mobile equipment identity in trunking manner IMEI.Know-why of the present invention is: a plurality of EIR equipment is set to a cooperation cluster, and wherein each EIR equipment all can independently receive IMEI check request and carry out quick IMEI verification; Arbitrary EIR ES that identify, specific mobile device in arbitrary IMEI verification changes and will be synchronously updated in cluster in other members in cluster, thereby guarantees can be updated in the MSC/SGSN at described mobile device place in the upper once IMEI verification for this specific mobile device; And after EIR is processed the ES variation of this specific mobile device, this processing can be synchronized in interior other EIR of cluster, to avoid repetitive operation equally.

According to above-mentioned know-why, the invention provides a kind of method for verifying international mobile equipment identity in trunking manner, as shown in Figure 2 A, comprise the following steps:

S1: in each equipment identity register EIR, cluster member list is set, for recording the common whole EIR equipment lists that form the cluster that cooperates with described EIR, be whole EIR equipment lists that cooperation cluster under this EIR equipment has been recorded in cluster member list in each EIR equipment, comprise this EIR equipment; And each member in cluster (being EIR equipment) all can independently carry out quick IMEI verification;

Wherein, can be by network manager according to the cooperate setting of cluster of actual conditions, such as being divided according to region, all EIR after dividing in each region are all set to a cooperation cluster; Certainly, can, according to the cooperate setting of cluster of other situations, not repeat them here yet.

Described record is deleted and is comprised: after at described EIR, based on it, the data record in local mobile device list is upgraded corresponding mobile device executing state, if described data record only relates to current mobile device, without continuing, retain, described EIR deletes described data record from its local mobile device list.

Can find out, because the present invention adopts the mode that between cluster EIR, local mobile device list synchronization changes, form by the instruction of the recognition result of this verification and required execution with data record is synchronously updated in the local mobile device list of other EIR in described EIR and cluster, the EIR(that can guarantee to carry out verification next time carries out one of the EIR of this IMEI verification or other cluster member) local mobile device list in comprised the data record generating according to this verification recognition result, therefore no matter whether mobile device is roamed, all can be to using in its IMEI verification next time to the recognition result of its last IMEI verification.

That is, the data record that the present invention generates last IMEI verification recognition result is synchronously updated in described EIR and other cluster member, on described mobile device carries out once during IMEI verification, even if described mobile device is roamed out the described EIR area of coverage and is entered the area of coverage of other cluster member, still can utilize synchronous data record that the equipment state of described mobile device is adjusted to the desired state of last verification, therefore, the situation that the entry-into-force time that can realize this check results when described mobile device roams into the area of coverage of described cluster EIR and described mobile device continue to reside in former EIR is identical, improved the utilance of check results, and avoided causing delaying of check results entry-into-force time because of mobile device roaming.

In addition, because data record (data record that only relates to mobile device individual cell) can be deleted after use from EIR, and synchronously delete the identical data record in cluster EIR equipment, can effectively control the length of the local mobile device list of EIR equipment and the storage of other cluster member, reach and shorten the IMEI verification response time, and the object of reducining the construction costs.

Further, the step that EIR described in described step S2 is synchronized to described direct variation in the local mobile device list of every other member in its cluster member list can take variety of way to be realized, for example by the EIR that occurs directly to change, to every other member in cluster member list, send synchronization request message, for example by the EIR that occurs directly to change, to CEIR, send synchronization request message, then to every other member in corresponding cluster member list, send synchronization request message etc. by CEIR.

Certainly, the present invention takes is synchronously updated to the check results identifying in this verification the corrective measure of other cluster member, can increase undoubtedly the exchanges data quantity between CEIR and EIR or EIR and other cluster member; But the data exchange process between the CEIR increasing and EIR or EIR and other cluster member as long as completed before next verification occurs; In real network environment, the occurrence frequency that mobile device is carried out to IMEI verification is higher, and the busy (period that traffic carrying capacity is the highest) in every day can reach 1 ~ 2 time per hour; And the general high speed interface that adopts Ethernet etc. between CEIR and EIR, EIR and other cluster member, so the disposal ability that above-mentioned exchanges data increases and data transfer load are acceptables.

For simplified signaling is as far as possible mutual and reduce the information redundancy in the local mobile device list of each EIR, the present invention, for EIR described in described step S2 is synchronized to described direct variation the specific implementation that step in the local mobile device list of every other member in its cluster member list provides following optimization, comprising:

Step S21: the EIR directly changing occurs described EIR() identify described direct variation; To every other member in cluster member list, send synchronization request message; Wherein, in described synchronization request message, carry newly-added information/the record deletion information that records of described local mobile device list;

Wherein, EIR can realize the monitoring of its local mobile device list by keeping the identification of described direct variation, the triggering after also can its local mobile device list of passive wait is each changing, and its specific implementation does not affect technique effect of the present invention;

Further, in a preferred embodiment, the EIR that receives described synchronization request message can send synchronous response message to the transmit leg EIR of described synchronization request message, therefore in this step, the EIR that occurs directly to change is after waiting for and receive the whole synchronous response message corresponding with sent synchronization request message, finish this device processes process and enter idle condition, until the directly variation or synchronously variation next time of local mobile device list;

If obtain and record deletion information, carry out the record deletion operation of local mobile device list: delete corresponding data record from local mobile device list;

In a preferred embodiment, the EIR that receives described synchronization request message can send synchronous response message to the transmit leg EIR of described synchronization request message, therefore in this step, the EIR that receives described synchronization request message can send to the transmit leg EIR of described synchronization request message after synchronous response message, finish this device processes process and enter idle condition, until the directly variation or synchronously variation next time of its local mobile device list.

Further, no matter whether adopt the synchronous implementation of above-mentioned optimization, can be all that corresponding data record arranges life cycle when the newly-increased operation of executive logging, for these data of mark, is recorded in the deadline date that EIR preserves; When the life cycle of a certain data record finishes, from local mobile device list, delete described data record; This deletion is not due to the deletion action after corresponding mobile device executing state is upgraded, and the data record that therefore finishes to delete because of life cycle does not form the direct variation of local mobile device list.For arranging life cycle, data record can in local mobile device list initialization process, arrange, it is long that the arranging of this life cycle can avoid some unnecessary data to be recorded in local mobile device list RT, and then shorten the response time of IMEI verification.

Further, can also be included in and carry out in quick IMEI checking procedure, when a certain EIR receives IMEI check request, according to its current disposal ability, carry out load balancing: identify its current disposal ability; When its current disposal ability is not enough, other EIR that received IMEI check request is transmitted in cluster processes; Otherwise directly processed by described EIR.Adopt after above-mentioned load balancing measure, make system possess process migration function, can effectively avoid the processing failure problem causing in the overload aspect traffic handing capacity due to indivedual EIR equipment;

Can find out, each member in cluster all can independently carry out quick IMEI verification and carry out load balancing, to improving the construction cost of the utilance of EIR equipment, the reliability/availability/extensibility that strengthens system and reduction system, will produce significant supporting role.

Fig. 2 B shows the flow chart of method one preferred embodiment of above-mentioned cluster verification IMEI.

Below in conjunction with exemplary parameter, existing quick IMEI checkschema and cluster checkschema provided by the invention are compared, so that those skilled in the art more easily grasp the features and advantages of the invention, but the not restriction to technical solution of the present invention of exemplary parameter.

Suppose that the mobile device parameter that certain IMEI verification relates to is as follows: IMEI is 11111111111111(14 position, has deleted standby number SP); The IMSI of the SIM card of using in described mobile device is that 222222222222222, MSISDN is 3333333333333; The current ES of the described mobile device of storing in MSC/SGSN is that 0(is put into white list); The target ES of the described mobile device of storing in the IMEI of CEIR central database is that 1(is put on the blacklist).

Existing quick IMEI checking procedure is as follows:

If at described MSC/VLR(or SGSN, the present embodiment is carried out verification with MSC and is reported as example, and MSC and VLR are integrated in one in the present embodiment) middle triggering IMEI verification, and " Extended Check IMEI " message is sent to the EIR(that possesses quick verifying function comprises for realizing the EIR of the unit of quick IMEI verification), in described " Extended Check IMEI " message, comprised mobile device triplet information <IMEI, IMSI, the current ES of MSISDN> and mobile device, EIR receives " Extended Check IMEI " message, the mobile device triplet information parsing is <11111111111111, 222222222222222, 3333333333333 >, the current ES of mobile device is 0, in the local mobile device list of EIR, there is no the data record matching with described mobile device, therefore, this verification is using current ES as check results and be encoded to " Extended Check IMEI Ack " message after send to described MSC/VLR, because check results is that 0(is put into white list), allow described mobile device to carry out access to netwoks,

EIR is the mobile device triplet information <IMEI obtaining in this verification, IMSI, and MSISDN> and current ES send to CEIR after being encoded to " Update ME Info Request " message; The triplet information that CEIR parses described mobile device is <11111111111111,222222222222222,3333333333333 >, and current ES is 0; CEIR is with triplet information <11111111111111, and 222222222222222,3333333333333 > are that the target ES that search index IMEI central database obtains described mobile device is 1; Due to current ES and target ES inconsistent, CEIR generates and comprises quaternary group information <IMEI, IMSI, MSISDN, the more newer command of ES>, concrete quaternary group information is <11111111111111,222222222222222,3333333333333,1>, being about to tlv triple is <11111111111111, and the ES of the mobile device of 222222222222222,3333333333333 > is set to 1; CEIR sends to EIR described renewal command code and reception result for after " Update ME Info Response " message; EIR receives " Update ME Info Response " message, and by the quaternary group information <11111111111111 parsing, 222222222222222,3333333333333,1> is compiled as a data record in local mobile device list;

If verification next time is still triggered by described MSC/VLR, EIR receives new " Extended Check IMEI " message, the mobile device triplet information parsing is <11111111111111,222222222222222,3333333333333 >, the current ES of mobile device is 0; With tlv triple <11111111111111,222222222222222,3333333333333 > inquire about local mobile device list, the ES comprising in the data record matching that obtains is 1, therefore, need to revise the ES of mobile device, using the ES in described data record as check results and after being encoded to " Extended Check IMEI Ack " message, send to described MSC/VLR, because check results is that 1(is put on the blacklist), refuse described mobile device and carry out access to netwoks; EIR deletes and comprises quaternary group information <11111111111111, the data record of 222222222222222,3333333333333,1>;

EIR is mobile device triplet information <IMEI, and IMSI, MSISDN> and current ES(are updated to 1 by above-mentioned checking procedure) send to CEIR after being encoded to " Update ME Info Request " message; The triplet information that CEIR parses described mobile device is <11111111111111,222222222222222,3333333333333 >, and current ES is 1; CEIR is with triplet information <11111111111111, and 222222222222222,3333333333333 > are that the target ES that search index IMEI central database obtains described mobile device is 1; Because current ES is consistent with target ES, do not need the ES of mobile device again to upgrade; CEIR sends to EIR after reception result being encoded to " Update ME Info Response " message; EIR receives " Update ME Info Response " message authentication checking procedure and completes;

If but verification next time triggers by new MSC/VLR, and " Extended Check IMEI " message is sent to new EIR, new EIR receives " Extended Check IMEI " message, the mobile device triplet information parsing is <11111111111111, 222222222222222, 3333333333333 >, the current ES of mobile device is 0, in the local mobile device list of new EIR, there is no the data record matching with described mobile device, therefore, using current ES as check results and after being encoded to " Extended Check IMEI Ack " message, send to described MSC/VLR, because check results is that 0(is put into white list), allow described mobile device to carry out access to netwoks,

New EIR is the mobile device triplet information <IMEI obtaining, IMSI, and MSISDN> and current ES send to CEIR after being encoded to " Update ME Info Request " message; The triplet information that CEIR parses described mobile device is <11111111111111,222222222222222,3333333333333 >, and current ES is 0; CEIR is with triplet information <11111111111111, and 222222222222222,3333333333333 > are that the target ES that search index IMEI central database obtains described mobile device is 1; Due to current ES and target ES inconsistent, CEIR generates and comprises quaternary group information <IMEI, IMSI, MSISDN, the more newer command of ES>, concrete quaternary group information is <11111111111111,222222222222222,3333333333333,1>, being about to tlv triple is <11111111111111, and the ES of the mobile device of 222222222222222,3333333333333 > is set to 1; CEIR sends to new EIR described renewal command code and reception result for after " Update ME Info Response " message; New EIR receives " Update ME Info Response " message, and by the quaternary group information <11111111111111 parsing, 222222222222222,3333333333333,1> is compiled as a data record in local mobile device list.

From above-mentioned example process, if once verification is triggered by new MSC/VLR in quick IMEI verification, and receive " Extended Check IMEI " message by new EIR, because of the data record of not mating with described mobile device in the local mobile device list of new EIR, verification next time fails to revise the state of described mobile device, and the entry-into-force time of this check results is delayed verification next time again.

By contrast, the method for cluster verification IMEI provided by the invention is the improvement to quick IMEI verification, and the process of the cluster verification IMEI after improvement is as follows:

If trigger IMEI verification in a MSC/VLR, and by " Extended Check IMEI " message be sent to possess quick verifying function EIR(for example, EIR M), in described " Extended Check IMEI " message, comprised mobile device triplet information <IMEI, IMSI, the current ES of MSISDN> and mobile device, EIR M receives " Extended Check IMEI " message, the mobile device triplet information parsing is <11111111111111, 222222222222222, 3333333333333 >, the current ES of mobile device is 0, in the local mobile device list of EIR M, there is no the data record matching with described mobile device, therefore, this verification is using current ES as check results and be encoded to " Extended Check IMEI Ack " message after send to described MSC/VLR, because check results is that 0(is put into white list), allow described mobile device to carry out access to netwoks,

EIR M is the mobile device triplet information <IMEI obtaining in this verification, IMSI, and MSISDN> and current ES send to CEIR after being encoded to " Update ME Info Request " message; The triplet information that CEIR parses described mobile device is <11111111111111,222222222222222,3333333333333 >, and current ES is 0; CEIR is with triplet information <11111111111111, and 222222222222222,3333333333333 > are that the target ES that search index IMEI central database obtains described mobile device is 1; Due to current ES and target ES inconsistent, CEIR generates and comprises quaternary group information <IMEI, IMSI, MSISDN, the more newer command of ES>, concrete quaternary group information is <11111111111111,222222222222222,3333333333333,1>, being about to tlv triple is <11111111111111, and the ES of the mobile device of 222222222222222,3333333333333 > is set to 1; CEIR sends to EIR M described renewal command code and reception result for after " Update ME Info Response " message; EIR M receives " Update ME Info Response " message, and by the quaternary group information <11111111111111 parsing, 222222222222222,3333333333333,1> is compiled as a data record in local mobile device list;

EIR M sends " ME List Syn Request " message as synchronization request message to other members in its cluster member list, should in " ME List Syn Request " message, carry above-mentioned quaternary group information and record newly-added information; Other cluster members receive " ME List Syn Request " message, parse quaternary group information <11111111111111,222222222222222,3333333333333,1> is also identified as and records newly-added information, is therefore compiled as a data record in local mobile device list;

Other cluster members EIR sends " ME List Syn Response " message as synchronous response message to EIR M, represents normally to receive and complete renewal process;

If verification next time is still triggered by described MSC/VLR, EIR M receives new " Extended Check IMEI " message, the mobile device triplet information parsing is <11111111111111,222222222222222,3333333333333 >, the current ES of mobile device is 0; With tlv triple <11111111111111,222222222222222,3333333333333 > inquire about local mobile device list, the ES comprising in the data record matching that obtains is 1, therefore, need to revise the ES of mobile device, using the ES in described data record as check results and after being encoded to " Extended Check IMEI Ack " message, send to described MSC/VLR, because check results is that 1(is put on the blacklist), refuse described mobile device and carry out access to netwoks; EIR M deletes and comprises quaternary group information <11111111111111, the data record of 222222222222222,3333333333333,1>; EIR M to other members in cluster (for example, EIR N) send " ME List Syn Request " message, the synchronic command that this message comprises requires to delete with quaternary group information <11111111111111,222222222222222,3333333333333,1> is the data record of feature;
