Method of Finding a Physical Location of a Mobile Telephone at a Given Time
First Claim
1. A method of finding a physical location of a mobile telephone at a given time, the method comprising:
- storing, in a subscriber database, data that are derived from, or are values of, mobile telephone control parameters associated with multiple mobile telephones on a network;
storing, in a location parameters database, location data that associates different physical locations with data that are derived from, or are values of, mobile telephone control parameters;
interpreting the data in the subscriber database for the purpose of establishing the location of a mobile telephone at the given time byusing that data as a query that is run against the location parameters database in order to generate an answer that is the location of that mobile telephone anddoing so only when there is an explicit request to establish the location of that one specific mobile telephone and not as part of a sequence of package of requests in relation to each of the multiple mobile telephones.

Abstract
A subscriber database, in at least one embodiment, stores RF level and timing advance information associated with all mobile telephones on a network. A location parameters database stores location data that associates different physical locations with RF levels/timing advance data that have been measured or inferred for those locations. The subscriber database is then interpreted for the purpose of establishing the location of a specific mobile telephone at a given time by matching the RF level/timing advance data for that specific mobile telephone against the location parameters database. This generates the location of the mobile telephone. The interpretation or querying of the subscriber database only occurs, however, when there is a request to establish the location of a specific mobile telephone, and not as an automated process applied to all mobile telephones on a network.
