Abstract
A system and method are disclosed for triggering location estimation of mobile stations in a geographic region of interest. The disclosed system includes a list of International Mobile Subscriber Identities ('IMSI') used to track which mobile stations are to have location estimates generated, a database of Network Measurement Reports ('NMR') used for generating the location estimates, and a location engine. The system operates as a group of concurrently executing processes that i) process IMSIs and NMRs that are extracted by and received from probes that monitor communication links; ii) generate location estimates of mobile stations in the region of interest, based on a sequential indexing of the IMSI list; iii) maintain the freshness of the NMR database; and iv) maintain the freshness of the IMSI list. These processes operate such that the triggering of the location estimations occurs asynchronously with respect to the detection of information on the communication links.
