Method and device for backfilling subscriber fixed identity

Abstract

Disclosed are a method and device for back filling a subscriber fixed identity. The method includes: acquiring signalling data of an A interface in the circuit switching (CS) domain and a GN interface of the packet switching (PS) domain (101); combining a CS domain call description record (CDR) and a PS domain call description record (CDR) according to the CS domain signalling data and PS domain signalling data respectively (102); extracting key information in the CDR of the CS domain and the CDR of the PS domain; the CS domain and PS domain back filling the international mobile subscriber identification number (IMSI) thereof according to the key information thereof respectively (104); by way of collecting signalling data, combing the CDR according to the signalling data and extracting key information and subscriber identity information in the CDR, after back filling the IMSI through the key information and the IMSI back filling the mobile subscriber international integrated service digital network code (MSISDN) / international mobile equipment identity (IMEI), synchronizing the subscriber identity information in the CS domain and PS domain, to realize the backfilling integration of the subscriber identity in the CS domain and PS domain to complete the CDR subscriber information.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, relates to a method and device for backfilling a user's fixed identity. Background technique [0002] With the continuous development of telecom network services, operators hope to analyze more specific user behaviors and location track information. However, in the signaling monitoring system, the user identity information carried in the signaling data, such as IMSI (International Mobile Subscriber Identification Number, International Mobile Subscriber Identification Number), MSISDN (Integrated Service Digital Network, integrated service digital network, is the calling The user calls the mobile phone number of the mobile user), IMEI (International Mobile Equipment Identity, International Mobile Equipment Identity), etc., are all incomplete, resulting in difficult and inaccurate analysis for the user level. Therefore, it is very important to backfill the user identity to t...

AI Technical Summary

Problems solved by technology

[0005] In view of this, the present invention provides a method and device for backfilling fixed user identities to overcome the problem in the prior art that the IMEI basically does not appear in the signaling data of the existing circuit domain network, and the MAP data of the circuit domain network is often not monitored. MSISDN and IMSI are not easy to obtain, so the function of business analysis based on IMEI / MSISDN in the circuit domain network cannot be realized
