Abstract

A system for providing location information to a mobile calling unit operating within or among a plurality of communication networks includes at least one communication access unit for each respective network of the plurality of communication networks. The calling unit effects communications with a respective communication network of the plurality of communicate networks via a respective communication access unit of the at least one communication access unit. The respective communication network and the respective communication access unit cooperate to automatically effect providing at least one almanac entry to the calling unit substantially on occurrence of a predetermined event. The at least one almanac entry relates to geographic location of the calling unit while the calling unit effects the communications.

2. The system for providing location information to a mobile calling unit operating within or among a plurality of communication networks as recited in claim 1 wherein said geographic location is expressed as an X-Y location.

3. The system for providing location information to a mobile calling unit operating within or among a plurality of communication networks as recited in claim 2 wherein said X-Y location is expressed in terms of at least one of latitude-longitude, radio frequency navigation system coordinates, and satellite navigation system coordinates.

4. The system for providing location information to a mobile calling unit operating within or among a plurality of communication networks as recited in claim 1 wherein said respective communication access unit is embodied in a cellular network base transceiver station.

5. The system for providing location information to a mobile calling unit operating within or among a plurality of communication networks as recited in claim 4 wherein said geographic location is expressed as an X-Y location.

6. The system for providing location information to a mobile calling unit operating within or among a plurality of communication networks as recited in claim 5 wherein said X-Y location is expressed in terms of at least one of latitude-longitude, radio frequency navigation system coordinates, and satellite navigation system coordinates.

7. The system for providing location information to a mobile calling unit operating within or among a plurality of communication networks as recited in claim 1 wherein said respective communication access unit is embodied in an access unit coupled for call routing via an Internet Protocol network to an Unlicensed Mobile Access Network or Global Area Network.

8. The system for providing location information to a mobile calling unit operating within or among a plurality of communication networks as recited in claim 7 wherein said geographic location is expressed as an X-Y location.

9. The system for providing location information to a mobile calling unit operating within or among a plurality of communication networks as recited in claim 8 wherein said X-Y location is expressed in terms of at least one of latitude-longitude, radio frequency navigation system coordinates, and satellite navigation system coordinates.

10. A system for providing location information to a mobile calling unit movingly operating within or among a plurality of communication networks;

the system comprising;

at least one communication access unit for each respective communication network of said plurality of communication networks;

said calling unit effecting communications with a plurality of respective contacted communication networks of said plurality of communication networks during said movingly operating via a plurality of respective contacted communication access units of said at least one communication access unit;

each said respective contacted communication network and a respective said contacted communication access unit cooperating to automatically effect providing geographic location of said respective contacted communication access unit to said calling unit

substantially on occurrence of a predetermined event while said calling unit effects said communications within said respective contacted communication network;

said calling unit storing said geographic information received from a plurality of said respective contacted communication access units in a database as said calling unit effects said movingly operating;

said database having a plurality of almanacs for access by said calling unit;

each said respective contacted communication access unit being associated with at least one respective almanac of said plurality of almanacs as a previously encountered communication access unit;

said calling unit employing said database to determine location of said calling unit as communication is established with a respective said previously encountered communication access unit without querying said previously encountered communication access unit regarding geographic location.

11. The system for providing location information to a mobile calling unit operating within or among a plurality of communication networks as recited in claim 10 wherein said predetermined event is at least one of a beginning of effecting said communication and an elapsing of a predetermined time interval.

12. The system for providing location information to a mobile calling unit operating within or among a plurality of communication networks as recited in claim 10 wherein said respective communication access unit is embodied in one of a cellular network base transceiver station and an access unit coupled for call routing via an Internet Protocol network to an Unlicensed Mobile Access Network or Global Area Network.

13. The system for providing location information to a mobile calling unit operating within or among a plurality of communication networks as recited in claim 11 wherein said respective communication access unit is embodied in one of a cellular network base transceiver station and an access unit coupled for call routing via an Internet Protocol network to an Unlicensed Mobile Access Network or Global Area Network.

14. The system for providing location information to a mobile calling unit operating within or among a plurality of communication networks as recited in claim 10 wherein said geographic location is expressed as an X-Y location.

15. The system for providing location information to a mobile calling unit operating within or among a plurality of communication networks as recited in claim 11 wherein said geographic location is expressed as an X-Y location.

16. The system for providing location information to a mobile calling unit operating within or among a plurality of communication networks as recited in claim 14 wherein said respective communication access unit is embodied in one of a cellular network base transceiver station and an access unit coupled for call routing via an Internet Protocol network to an Unlicensed Mobile Access Network or Global Area Network.

17. The system for providing location information to a mobile calling unit operating within or among a plurality of communication networks as recited in claim 15 wherein said respective communication access unit is embodied in one of a cellular network base transceiver station and an access unit coupled for call routing via an Internet Protocol network to an Unlicensed Mobile Access Network or Global Area Network.

18. A method for providing location information to a mobile calling unit movingly operating within or among a plurality of communication networks;

the method comprising;

(a) providing at least one communication access unit for each respective network of said plurality of communication networks;
