Method and apparatus for obtaining floating information of user floating between administrative regions

摘要

Disclosed are a method and an apparatus for obtaining the floating information of users floating between administrative regions. The method comprises: within a floating information statistical time range for mobile phone users, making statistics for mobile phone users entering an administrative region by using final effective location information corresponding to a location update request sent by a mobile phone entering the administrative region, corresponding international mobile subscriber identity IMSI_LUP information, and a Location Area Code LAC_CONF set of the administrative region; and within the floating information statistical time range for mobile phone users, making statistics for mobile phone users leaving the administrative region by using international mobile subscriber identity IMSI_LC information of a cancel location message sent by all Home Location Registers (HLR) in the administrative region. The present invention can accurately acquire the floating condition of the inter-city, inter-province, and inter-country international mobile subscribers.

1. A method for obtaining information of mobile phone users floating between administrative regions, comprising:
within a statistical time range of the information of floating mobile phone users, making statistics on the mobile phone users entering an administrative region by virtue of final valid location information contained in location update request messages sent by the mobile phones changing their location areas, International Mobile Subscriber Identity information of the mobile phones changing their location areas (IMSI_LUP) and a set of Location Area Codes of the administrative region (LAC_CONF set); and within the statistical time range of the information of the floating mobile phone users, making statistics on the mobile phone users leaving the administrative region by virtue of International Mobile Subscriber Identity information contained in all cancel location messages (IMSI_LC), wherein the cancel location messages are received by Visitor Location Registers (VLRs) in the administrative region, wherein the final valid location information contained in the location update request messages includes Location Area Code (LAC_LUP), wherein the making statistics on the mobile phone users entering the administrative region comprises: searching out one by one an LAC which corresponds to the final valid location information but is beyond the LAC_CONF set, and determining a mobile phone user whose IMSI_LUP information corresponds to the LAC beyond the LAC_CONF set as the user entering the administrative region, wherein the making statistics on the mobile phone users leaving the administrative region comprises: performing one-by-one searching to determine whether the IMSI_LC in each cancel location message is subjected to location update or tracking area update before the cancel location message is sent, and determining a mobile phone user whose IMSI_LC is not subjected to the location update or tracking area update as the user leaving the administrative region.
