Description
Technical field
The present invention relates to mobile communication technology fields, know it is more particularly related to which a kind of base station 4G obtains terminal
The system and device of other code.
Background technique
International mobile equipment identification number (International Mobile Equipment Identity, IMEI) is that is, logical
Often described handset serial, mobile phone " string number ", each mobile terminal device corresponds to a unique IMEI, is equivalent to shifting
The identity card of dynamic terminal.
The 4G information collecting device that the law enforcement agencies such as public security at present use can only be realized using the acquisition base station of LTE to shifting
The IMSI information of dynamic terminal is acquired, can not acquisition terminal identification code (IMEI) for data and identity analysis and retrieval.
According to LTE protocol, mobile phone terminal Idle state can initiate random access to acquisition base station and request location updating, then
Acquisition base station can construct plaintext NAS message and issue Identity Request, request IMSI certification, user feedback Identity
Response, carries the IMSI information of user, and user information collection is completed in acquisition base station, then with (TAU Reject) message come
The update for refusing UE, then issues RRC Release, and purpose disengages it from acquisition base station, returns to carrier network.If base station side
Conventional access process issues Identity Request, carries and obtains IMEI request, and mobile phone, can not under this normal mode without response
Get IMEI.
In addition, traditional 4G acquisition equipment can not connect the core net of operator, and LTE protocol is in the process for obtaining IMEI
Upper having time and guaranteed request is encrypted, base station side can not persistently interact under the scene for being detached from core net, i.e., can not be initial
Signalling exchange process on obtain the IMEI of terminal, therefore the IMEI information of terminal can only be obtained under 3G/2G standard.This is greatly
The separate unit acquisition equipment that increases obtain information and the matched difficulty such as IMSI and IMEI, also increase the complexity of acquisition equipment
And compatibility, improve the hardware and software cost of acquisition equipment.
Summary of the invention
In order to overcome the drawbacks described above of the prior art, the embodiment of the present invention provides a kind of base station 4G acquisition terminal recognition code
System and device, behavioral analysis technology is accessed based on terminal, is classified by access to end message, passes through different signaling controls
It makes and terminal is induced to report IMEI, background analysis system is reported, while terminal is released back into operator base station, for hotspot device
User for, sufficiently used 4G acquisition base station acquisition capability, the IMEI of terminal can be obtained directly under the base station 4G, is
The end message that user provides effectively, various is analyzed.
To achieve the above object, the invention provides the following technical scheme: a kind of base station 4G obtain terminal recognition code system,

Enter end connection；
Terminal accesses behavioural analysis module, and the access request of terminal, and analysis request are obtained for being responsible for base station；
Signaling sends judging module, sends, can be sentenced according to the access request of different terminals for being responsible for NAS refusal information
Certainly whether issue different NAS REJECT；
IMEI acquisition request sending module, the IMEI for being responsible for coding plaintext request Identity Request,
Identity Type=2 information is handed down to terminal；
Signaling receives decoding judging module, and the Identity Response for being responsible for deciding whether to receive simultaneously is decoded,
IMEI is obtained, the NAS TAU/ATTACH_reject for carrying different cause values is issued further according to content judgement；
Information storage module, the IMEI for being responsible for will acquire are converted into effective IMEI storage and report；
Terminal release module redirects the terminal to specified network for being responsible for release terminal.
A kind of base station 4G obtains the device of terminal recognition code, and the base station including TDD and FDD standard, the base station passes through 4G
Network connection terminal.
Technical effect and advantage of the invention:
The present invention can be obtained by proposing that a kind of LTE acquires the system and device of acquisition 4G cell phone terminal IMEI under base station
The IMEI for taking target terminal has sufficiently used the acquisition capability of 4G acquisition base station for the user of hotspot device, can be straight

1. receiving the Identity Response of terminal feedback, and code stream analyzing dentity within timer T validity period
Type=2, the then identity information obtained are IMEI, stop timer T, and subsequent notification information storage module 5 carries out IMEI (the
15, it is that the conversion of 0) significance bit is calculated and stored that terminal, which reports last position IMEI,；
2. timer T time-out, the Identity Response subsequent processing for not receiving terminal feedback are as follows:
It is accessed if TAU, notice signaling receives decoding judging module 4, sends TAU_reject and discharges terminal, sends out at this time
The NAS Reason For Denial for sending carrying is 10 (Implicitly detached), and subsequent notification terminal release module 6 issues RRC_
Release message carries 4G and redirects cell information (carrying this base station cell frequency point) to terminal；
It being accessed if ATTACH, notice signaling receives decoding judging module 4, and it sends ATTACH_reject and discharges terminal,
The NAS Reason For Denial for sending carrying at this time is 10 (Implicitly detached), and subsequent notification terminal release module 6 issues
RRC_release message carries 4G and redirects cell information (carrying this base station cell frequency point) to terminal；
Step 5: information storage module 5 sends the IMEI code stream that judging module 2 is sent according to signaling, Luhn algorithm is called
The 15th bit check position is calculated according to 14 data before IMEI, is formed new IMEI (15), acquisition time is associated with and is stored, after
Continuous notice terminal release module 6, normally discharges UE；
Step 6: terminal release module 6 receives the normal release end command that information storage module 5 is sent, issue
Attach_Reject (cause=15, No Suitable Cells In tracking area) and RRC_Release
(cause=other, redirectedCarrierInfo=operator frequency point) gives terminal, is returned to carrier network, adopts
Collection terminates.
