Abstract:
1. A method for tracking mobile devices combining network processor packet processing technology with Global Positioning System (GPS) technology, comprising the steps of: providing at least one mobile device transmitting GPS location packet format data and identification data; a network processor building a look-up key with the transmitted GPS data and retrieving X-Y coordinate data from an X-Y coordinate table with the look-up key through a network processor table access scheme executed on at least one network processor hardware assist coprocessor, at least one network processor protocol processor and a network processor embedded memory; the network processor comparing the retrieved X-Y coordinate data to a first map structure comprising a plurality of location zones, correlating a first map location zone corresponding to the retrieved X-Y coordinate data with the transmitted identification data and writing the correlated first map location zone and identification data into a tracking table entry in a tracking table; and the network processor comparing the first map location zone and identification data with a plurality of billing zones within a billing table and producing a billing charge responsive to a correlation of the first map location zone with at least one of the billing zones.
