Problems solved by technology

[0002] LTE cannot obtain the user's IMSI number on the wireless side
MR is the wireless measurement report (MeasureReport) of LTE, which contains the ID of the serving cell and the ID of the adjacent cell. However, the mobile subscriber number MSISDN and IMSI number of the user are not reflected in the MR database of the wireless measurement report. As a result, when using MR, it cannot Effectively correspond to specific IMSI users

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the embodiments and accompanying drawings, but the protection scope of the present invention should not be limited thereby.

[0024] Due to the large amount of MR data, the present invention should adopt a big data platform. The data sources of this patent positioning system are the wireless measurement report MR database of the LTE wireless side and the call history record signaling bill CHR database of the core network side, and the above data sources are provided to figure 1 The positioning device shown, such as a computer, etc. The data format of the wireless measurement report MR database is as follows: figure 2 as shown,

[0025] MMEGI (MME Group ID): MME group number

[0026] MMEC (MME Code): MME number

[0027] MME UE S1AP ID: MME UE S1 Application Protocol ID number

[0028] eNB ID (eNodeB ID): eNodeB base station number

[0029] Time: the timestamp corresponding to the MR

Abstract

The invention discloses a method for calculating the location of a mobile subscriber of an IMSI (International Mobile Subscriber Identity) number by an LTE network according to records of a wireless measurement report (MR). The method comprises the steps of 1, querying related fields according to the positioned imsi number and time in a core network signalling call history record (CHR) database; 2, finding out a corresponding Serving Cell ID, a Neighbor 1 Cell ID, a Neighbor 2 Cell ID and a Neighbor 3 Cell ID in an MR database; and 3, calculating the location of the IMSI subscriber through querying a base station basic information database. The method solves a problem of great positioning error caused by a circumstance that application of the MR cannot effectively correspond a specific IMSI subscriber to information of the base station basic information database.

Description

technical field [0001] The invention belongs to the field of data mining and analysis in mobile communication, and in particular relates to a method for calculating the position of a mobile user with an IMSI number by an LTE network according to a wireless measurement report MR record. Background technique [0002] LTE cannot obtain the user's IMSI number on the wireless side. MR is the wireless measurement report (MeasureReport) of LTE, which contains the ID of the serving cell and the ID of the adjacent cell. However, the mobile subscriber number MSISDN and IMSI number of the user are not reflected in the MR database of the wireless measurement report. As a result, when using MR, it cannot Effectively correspond to specific IMSI users. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned existing problems, and provide a method for calculating the location of a mobile user with an IMSI number in an LTE network according ...
