<p>Disclosed is a method for screening a high-speed moving cellular phone user, comprising: comprehensively monitoring an A/C/E interface of a GSM network, and ensuring a high back-fill rate of a normal location-updated IMSI using the associated back-fill technology of a signalling monitoring system; setting a location-updated LAC as a high-speed rail private network LAC, and performing location-updated LAC filtering on an hourly location-updated record to delete a location-updated call detail record of a location-updated LAC which is not a high-speed rail private network LAC; calculating a minimum time difference and a maximum time difference entering and leaving the high-speed rail private network LAC respectively; and judging whether the time difference list of each IMSI entering and leaving each high-speed rail private network LAC is greater than or equal to the minimum time difference and less than or equal to the maximum time difference, if yes, determining an IMSI which conforms to the time requirement. Therefore, the collection of a vast amount of measurement reports on an Abis interface is omitted, and the collection time and hardware cost are saved.</p> |
