Abstract

A method of registering a mobile device in a mobile telecommunications network comprises the device'"'"'s receiving power from a power source and transmitting a registration request signal including mobile device identification data, an associated mobile network determining a set of latitude and longitude location coordinates for the transmitting mobile device, comparing the determined set of latitude and longitude location coordinates with a table for matching the location coordinates with a service area code, determining a service area code responsive to the comparison, and storing the service area code, the mobile device identification data, the determined service area code and a location area code of the associated public mobile network for registering the mobile device in the associated mobile network. A related mobile device comprises a power source, a processor for determining whether power has been actuated, a global positioning system for determining a set of latitude and longitude location coordinates for the transmitting mobile device, the processor for comparing the determined set of latitude and longitude location coordinates with a table for matching the location coordinates with a service area code, determining a service area code responsive to the comparison and storing the service area code in memory of the mobile device.

2. A method of registering a mobile device in a mobile telecommunications network as recited in claim 1 further comprising tracking the registration of the mobile device in the at least one service area code by time of day over time and storing a plurality of mobile device service area codes based on the tracking of the mobile device registration by time of day over time where the time period is at least one day.

3. A method of registering a mobile device in a mobile telecommunications network as recited in claim 2 wherein the tracking over time comprises a weekly collection and storing of mobile registration data.

4. A method of registering a mobile device in a mobile telecommunications network as recited in claim 1 further comprising downloading the current service area code registration data to the mobile device for storage in memory thereof.

5. A method of registering a mobile device in a mobile telecommunications network as recited in claim 4 further comprising receiving a registration request signal including mobile device identification data and the service area code registration data stored in mobile device memory.

6. A method of registering a mobile device in a mobile telecommunications network comprising:

receiving a registration request signal including mobile device identification data at a controller;

an associated mobile network determining geographic location data for the transmitting mobile device;

comparing the geographic location data with a table for matching the location data with at least one service area code;

determining the at least one service area code responsive to the comparison; and

storing the determined service area code, the mobile device identification data and a location area code of the associated mobile network for registering the mobile device in a location register of the associated mobile network.

7. A method of registering a mobile device in a mobile telecommunications network as recited in claim 6 further comprising tracking the registration of the mobile device in the at least one service area code over time and storing a plurality of mobile device service area codes by time of day based on the tracking of the mobile device registration over time where the time period is one day.

8. A method of registering a mobile device in a mobile telecommunications network as recited in claim 7 wherein the tracking over time comprises a weekly collection and storing of mobile registration data.

9. A method of registering a mobile device in a mobile telecommunications network as recited in claim 6 further comprising downloading the current service area code registration data to the mobile device for storage in memory thereof.

10. A method of registering a mobile device in a mobile telecommunications network as recited in claim 9 further comprising receiving a registration request signal including mobile device identification data and the service area code registration data stored in mobile device memory.

11. A mobile device comprising:

a power source;

a processor for determining whether power has been actuated;

a global positioning system for determining a set of latitude and longitude location coordinates for the mobile device, the processor for comparing the determined set of latitude and longitude location coordinates with a table for matching the location coordinates with a service area code, determining a service area code responsive to the comparison and storing the service area code in memory of the mobile device; and

the memory of the mobile device.

12. A mobile device as recited in claim 11 further comprising a transceiver for receiving paging request signals and for periodically transmitting a registration request signal including mobile device identification data and the stored service area code when the power source is turned on.

13. A mobile device as recited in claim 12, the transceiver for receiving a signal including data representing a service area code for comparison with the stored service area code and transmitting an error signal if the stored area code is different from the received service area code.

14. A method of registering a mobile device in a mobile telecommunications network comprising:

receiving a registration request signal from a mobile device including determined location coordinates for said mobile device and mobile device identification data;

comparing the received, determined set of latitude and longitude location coordinates with a table for matching the location coordinates with a service area code;
