1. A method of determining the location of a mobile device, comprising:
- receiving at least one mobile communication operating parameter from the mobile device, the at least one communication operating parameter comprising Timing Advance (TA) zone data;
referring to a database of stored TA zone data and associated location data, the database further comprising TA zone form data representative of the shape and size of each TA zone, each TA zone having a polygonal shape having greater than 4 vertices, the TA zone form data being derived by processing TA zone data and associated location data received from a plurality of navigation devices; and
determining the location of the mobile device from the received at least one mobile communication operating parameter and data retrieved from the database, wherein determining the location of the mobile device from the determined mobile communication operating parameter and the data from the database comprises pattern matching a variation of the received mobile communication operating parameter to the stored data.
