Method for screening high-speed mobile phone user

Abstract

The invention discloses a method for screening a high-speed mobile phone user. The method comprises the following steps of: comprehensively monitoring an A/C/E interface of a global system for mobile communication (GSM) network, and ensuring the high international mobile subscriber identity (IMSI) backfilling rate of normal location update by utilizing an associated backfilling technology of a signaling monitoring system; setting a location area code (LAC) corresponding to an updated location as a high-speed railway network LAC, filtering LACs corresponding to updated locations in location update records of every hour, and deleting the updated location records of the updated locations of which the corresponding LACs are not the high-speed railway network LAC; calculating a minimum difference and a maximum difference of time when each IMSI enters the high-speed railway network LAC; and judging whether a time difference table for each IMSI entering each high-speed railway network LAC is more than or equal to the minimum time difference and less than or equal to the maximum time difference or not, and if the time difference table is more than or equal to the minimum time difference and less than or equal to the maximum time difference, determining the IMSI meets time requirements. Therefore, the acquisition of massive measurement reports for an Abis interface is eliminated, so that acquisition time cost and hardware cost are saved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to the field of signaling monitoring of a mobile communication network. Background technique [0002] Due to the closer communication and cooperation between different cities in the city circle, the completion of high-speed railways and expressways has effectively promoted the flow of people, technology, capital and information between various regions, and promoted the development of surrounding areas. In order to ensure the smooth communication of a large number of mobile users on high-speed railways or highways between cities, communication operators have gradually shifted their work focus to the construction and optimization of private networks covering high-speed railways or highways. The evaluation of the network through user perception has become the focus and difficulty of communication operators' maintenance and optimization of the network. At present, one of the difficu...
