User number backfill method and number backfill server based on intra-network inter-dial call

Abstract

The invention discloses a user number backfilling method and a number backfilling server based on mutual network dialing and calling. The user number backfilling method includes: establishing a TMSI (temporary mobile subscriber identity)-GROUPID corresponding relation table; establishing a TMSI-GROUPID-IMSI (international mobile subscriber identity) corresponding relation table; supplementing the IMSI to the TMSI-GROUPID corresponding relation table and establishing the complete TMSI-GROUPID-IMSI corresponding relation table; respectively obtaining corresponding relations between GROUPID of a calling party and an MSISDN mobile station international service digital number as well as between GROUPID of a called party and the MSISDN mobile station international service digital number according to characteristics of the in-network mutual dialing and calling; subjecting call records of the calling party and the called party to IMSI and MSISDN number backfilling and storing the call records, after number backfilling, into user call records. In the method, related mobile network interfaces are few, so that the user number backfilling method is easy to apply and deploy to a current signaling monitoring system.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for backfilling user numbers based on inter-network inter-dial calls, which is used for the International Mobile Subscriber Identity Number (IMSI) and the International Mobile Station International Integration Number (IMSI) of user call records in the mobile communication network signaling monitoring system. Backfilling of MSISDN to distinguish call records of different users. Background technique [0002] The user call record in the mobile communication network signaling monitoring system, because in the user call signaling process, the user's temporary mobile subscriber identity TMSI is used to identify the user. TMSI is a temporarily assigned number and cannot correspond to a specific user. Therefore, , need a method for backfilling user IMSI, MSISDN, the user call record is marked with IMSI, MSISDN label, in order to distinguish different user calls. [0003] At ...

AI Technical Summary

Problems solved by technology

At present, the mobile network is very large. It is a costly project to monitor the A interface, Mc interface, IUCS interface, C interface and D interface in the whole network, and the engineering complexity is quite high. Therefore, this technology is only suitable for few A signaling monitoring network that monitors all of the above-mentioned interfaces

[0006] 2. Because this technology needs to match the signaling of multiple interfaces, the signaling analysis and number matching algorithms are very complicated, which seriously affects the real-time performance of user numbers, and cannot obtain user numbers in real time for backfilling, which is not suitable for systems with high real-time requirements. Be applicable

[0007] 3. This technology does not use the characteristics of intra-network inter-dial calls to match user numbers. This type of calls accounts for more than 70% of the total call volume in the live network, and there is still room for improvement in the number matching rate.

[0009] 1. This technology can only match the user's IMSI, but cannot obtain the user's MSISDN for backfilling, that is to say, it cannot obtain the user's mobile phone number, and is not suitable for applications such as user tracking and user complaint handling

[0010] 2. This technology does not use the characteristics of intra-network inter-dial calls to match user numbers. This type of calls accounts for more than 70% of the total call volume in the live network, and there is still room for improvement in the number matching rate.
