Abstract

The invention discloses a kind of methods of association LTE network wireless measurement report MR record ownership IMSI number, comprising: 1. reports that relevant field searches MME relevant field in MR database by LTE wireless measurement；2. obtaining the corresponding IMSI number of this MR data by MME relevant field in LTE core network database.The problem of measurement report MR data that the present invention solves previous wireless side can not correspond to IMSI number, and wireless side analysis can only cannot be based on particular user based on cell.

Description

The method for being associated with LTE network wireless measurement report MR record ownership IMSI number

Technical field

The invention belongs to data mining analysis fields in mobile communication, and in particular to a kind of association LTE network wireless measurement Report the MR method of record ownership IMSI number.

Background technique

According to agreement, LTE can not obtain the IMSI number of user in wireless side.MR is the wireless measurement report of LTE (Measure Report), (Reference Signal Receiving Power reference signal receives function to RSRP therein Rate), RSRQ (Reference Signal Receiving Quality Reference Signal Received Quality) is able to reflect in cell User's impression, but the cell-phone number MSISDN and IMSI number of user are not embodied in wireless measurement report MR lane database, Cause wireless side when analysis user experiences, can only be counted by cell, can not effectively be directed to particular user.

Summary of the invention

It is an object of the invention to solve above-mentioned existing issue, a kind of association LTE network wireless measurement report MR note is provided The affiliation method for recording IMSI number is led to by the inquiry of MR relevant field in LTE wireless side measurement report data library by processing It crosses and the association of LTE core network database CHR (call history), analysis obtains the home subscriber IMSI of MR record.

Technical solution of the invention is as follows:

A method of association LTE network wireless measurement report MR record ownership IMSI number, it is characterized in that: this method packet Include following steps:

Extracted in step 1) wireless measurement report database MME UE S1AP ID of MR to be checked record, MMEC, MMEGI, ENB ID and Time field；

MME UE S1AP ID, MMEC, MMEGI, eNB ID in step 1) from the decimal system is converted to 16 by step 2) System, wherein MMEGI is converted to four hexadecimal numbers, is set as G0G1G2G3, and then left two are exchanged with right two, obtains G2G3G0G1；MMEC is converted to two hexadecimal numbers, is set as C0C1；MME UE S1AP ID is converted to hexadecimal, is set as S；ENB ID is converted into hexadecimal, is set as Nb；Time value is constant, is set as time_value；

Step 3), according to eNB ID, is inquired in time_value in core network signalling call history CHR database The device number device_num of 16 bytes in the nearest time, is set as DN0DN1DN2DN3DN4DN5DN6DN7DN8DN9DN1 0DN11DN12DN13DN14DN15；

Step 4) is made of new device_numnew MMEGI, MMEC and device_num data, and rule is as follows:

6 remain unchanged before device_num, and the 7th~10 replaces with the MMEGI that step 2) obtains, and the 11st~12 is replaced It is changed to the MMEC that step 3) obtains, rear 4, the right remains unchanged, i.e. DN0DN1DN2DN3DN4DN5G2G3G0G1C0C1DN12D N13DN14DN15；

The hexadecimal MME UE that the device_numnew and step 2) that step 5) is obtained according to step 4) are obtained S1AP ID, eNB ID value S, Nb and original time value time_value press following this of condition query MR in CHR table The IMSI number of record:

Device_num is equal to device_numnew,

Mme_uesiap is equal to 0xS,

Enodeb_id is equal to N,

time_value-180<mme_uesiap_utc<time_value+180；

Step 6) obtains the IMSI number of this MR record.

180 are added and subtracted on the mme_uesiap_utc time: referring to 180 seconds 3 minutes time deviations.

The condition query is pressed in CHR table, can be obtained the corresponding IMSI of the MR.

The requirement for inquiring field used is as follows: using in MR table MME relevant field MME UE S1AP ID, MMEC, MMEGI and base station NodeB relevant field eNB ID and time Time Field Inquiry.

When inquiring CHR table, time conditions mme_uesiap_utc should be recorded in MR and be obtained time time_value Front and back 3 minutes within the scope of.

Compared with prior art, the beneficial effects of the present invention are:

By the extraction to specific fields in MR table, the relevant field of core network signalling is converted to, and is limited in certain In time range, the search efficiency that MR records corresponding IMSI number is effectively improved, to solve previous LTE wireless side The problem of MR data can not be associated with core net IMSI data creates condition for the wireless aware analysis based on user.Have Preferable application value.

As shown in Figure 1: first to wireless measurement report MR table record to be checked extract MME UE S1AP ID, MMEC, MMEGI, eNB ID, Time field after converting to MMEGI, with original device_num in CHR table, are combined into new Device number device_numnew, and be associated with other relevant fields in CHR table, it is contemplated that the regular hour is poor, inquires The ownership IMSI number of this MR record.

It is specific as follows:

1) extracted simultaneously in LTE wireless measurement report database MME UE S1AP ID of MR to be checked record, MMEC, MMEGI, eNB ID, Time field；

2) 1) MME UE S1AP ID, MMEC, MMEGI, eNB ID in from the decimal system are converted to hexadecimal.Wherein MMEGI becomes four hexadecimal numbers, is set as G0G1G2G3, and then left and right two is mutually changed to G2G3G0G1.MMEC becomes two Hexadecimal number is set as C0C1.MME UE S1AP ID is converted to hexadecimal, is set as S.After eNB ID is converted into hexadecimal It is set as Nb.Time value is constant, is set as time_value.

3) it in the core network signalling CHR database of LTE, according to eNB ID, inquires within the time_value nearest time 16 bytes device number device_num, be set as DN0DN1DN2DN3DN4DN5DN6DN7DN8DN9DN10DN11DN12D N13DN14DN15。

4) by 2) 3) MMEGI, MME Code and device_num data, 6, the left side device_num remain unchanged, 7~10 replace with transformed MMEGI (i.e. G2G3G0G1), and the 11st~12 replaces with MMEC (i.e. C0C1), 4, the right guarantor It holds constant, forms new device_numnew:DN0DN1DN2DN3DN4DN5G2G3G0G1C0C1DN12DN13DN14 DN15.

5) according to new device_numnew, and be converted into hexadecimal MME UE S1AP ID, eNB ID value S, The IMSI number recorded in CHR table by following this of condition query MR: Nb and original time value time_value is set Standby number is equal to device_numnew, and mme_uesiap is equal to 0xS, and enodeb_id is equal to N, and the mme_uesiap_utc time > Time_value-180 the and mme_uesiap_utc time < time_value+180.Plus-minus 180 refers to 3 minutes on time 180 seconds.

The measurement report MR data that the present invention solves previous wireless side can not correspond to IMSI number, and wireless side analysis can only The problem of cannot being based on particular user based on cell.
