Abstract

A method for determining location information used in an electronic device of a communication system including a plurality of electronic devices, comprising: transmitting a position request signal via a plurality of communication networks of the communication system; receiving a position response signal with respective location information from at least one electronic devices of the plurality of electronic devices; and determining position information of the electronic device by the received position response signal; wherein the position request signal is transmitted successively to the plurality of networks in a specific order among said networks until the location information of the electronic device is determined based on the location response signal.

Claims

1. A method for determining location information used in an electronic device of a communication system including a plurality of communication devices, comprising:

transmitting a location request signal via a plurality of communication networks of the communication system;

receiving a location response signal with respective location information from at least one communication device of the plurality of communication devices; and

determining location information of the electronic device as a function of the received location response signal;

wherein the location request signal is transmitted successively to different networks in a specific order among said networks until the location information of the electronic device is determined based on the location response signal.

2. The method according to claim 1, wherein the specific order among said networks includes an ascending order of coverage range of the plurality of communication networks.

3. The method according to claim 1, wherein the communication device comprises one or more of the following:

4. The method according to claim 1, wherein the step of determining further comprises:

when more than one location information is received, the location information of the electronic device is obtained by averaging the more than one location information.

5. The method according to claim 1, wherein the location request signal and the location response signal is transmitted via wireless communication.

6. The method according to claim 1, wherein the location information includes position coordinates of Global Positioning System coordinates.

8. The electronic device according to claim 6, wherein the specific order among said networks includes an ascending order of coverage range of the plurality of communication networks.

9. The electronic device according to claim 6, wherein when more than one location information is received, the processing device is adapted to determine the location information of the electronic device by averaging the more than one location information.

10. The electronic device according to claim 6, wherein the location request signal and the location response signal is transmitted via wireless communication.

11. The electronic device according to claim 6, wherein the location information includes position coordinates of Global Positioning System coordinates.

7. An electronic device of a communication system including a plurality of electronic devices, comprising:
