Abstract

A method of selecting a wireless communication network, where each wireless communication network has one or more base transceiver stations. The method includes receiving

a first signal from a first base transceiver station of a first wireless communication network. The first signal is indicative of one or more communication service types offered by the first wireless communication network. The method further includes receiving a second signal from a second base transceiver station of a second wireless communication network. The second signal is indicative of one or more communication service types offered by the second wireless communication network. One of the first and second wireless communication networks is selected based at least in part on the first and second signals.

Claims

1. A method of selecting a wireless communication network each having one or more base transceiver stations, comprising:

receiving a first signal from a first base transceiver station of a first wireless communication network, wherein the first signal is indicative of one or more communication service types offered by the first wireless communication network;

receiving a second signal from a second base transceiver station of a second wireless communication network, wherein the second signal is indicative of one or more communication service types offered by the second wireless communication network;

selecting one of the first and second wireless communication networks based at least in part on a degree of match between the offered communication service types and a communication service type required by a mobile station.

2. A method as defined in claim 1, wherein the first and second wireless communication networks are first and second Public Land Mobile Networks (PLMN).

3. A method as defined in claim 1, wherein the offered communication service types are defined by at least one of bandwidth size, guaranteed bandwidth and non-guaranteed bandwidth.

4. A method as defined in claim 1, wherein the first and second signals are received as part of the wireless communication network system information.

5. A method as defined in claim 1, wherein selecting one of the first and second wireless communication networks is further based at least in part on a signal strength of each of the first and second signals.

6. A method as defined in claim 1, wherein selecting one of the first and second wireless communication networks is further based at least in part on the most efficient use of communication resources of the first and second wireless communication networks.

7. A method as defined in claim 1, wherein selecting one of the first and second wireless communication networks is further based at least in part on communication service types required by a mobile station.

8. A method as defined in claim 7, wherein selecting one of the first and second wireless communication networks comprises selecting a wireless communication network that provides the closest match between the offered communication services types and the required communication service types.

9. A method as defined in claim 7, wherein the required communication service types are the minimum communication service types required by the mobile station, and

wherein selecting one of the first and second wireless communication networks is further based at least in part on communication service types preferred by a user of the mobile station.

10. A method as defined in claim 9, wherein selecting one of the first and second wireless communication networks comprises selecting a wireless communication network that provides the closest match between the offered communication service types and the preferred communication service types.

11. A method of selecting a communication network comprising:

connecting to a first wireless communication network having one or more offered communication service types;

evaluating a degree of match between the offered communication service types of the first wireless communication network and one or more communication service types required by a mobile station;

receiving a signal from a base transceiver station of a second wireless communication network, wherein the signal is indicative of one or more communication service types offered by the second wireless communication network;

comparing the offered communication service types of the second network to the required communications service types; and

connecting to the second network if the offered communication service types of the second network provides a closer degree of match to the required communication service types than the first degree of match.

12. A method as defined in claim 11, wherein the first and second wireless communication networks are first and second Public Land Mobile Networks (PLMN).

13. A method as defined in claim 11, wherein the offered communication service types are defined by at least one of bandwidth size, guaranteed bandwidth and non-guaranteed bandwidth.

14. A method as defined in claim 11, wherein the signal is received as part of the system information of the second wireless communication network.

15. A method as defined in claim 11, wherein connecting to the second wireless communication networks is further based at least in part on a signal strength of the signal.

16. A method as defined in claim 11, wherein connecting to the second wireless communication network is further based at least in part on the most efficient use of communication resources of the first and second wireless communication networks.

17. A method as defined in claim 11, wherein the required communication service types are the minimum communication service types required by the mobile station, and

wherein connecting to the second wireless communication network is further based at least in part on communication service types preferred by a user of the mobile station.

18. In a mobile station, wherein the mobile station is capable of communicating with one or more base transceiver stations within one or more wireless communication networks, wherein the mobile station requires one or more communication service types, and wherein the mobile station operates in accordance to a logic circuit for enabling selection of a wireless communication network, the logic circuit comprising:

a first logic that directs the logic circuit to receive a first signal from a first base transceiver station of a first wireless communication network, wherein the first signal is indicative of one or more communication service types offered by the first wireless communication network;

a second logic that directs the logic circuit to receive a second signal from a second base transceiver station of a second wireless communication network, wherein the second signal is indicative of one or more communication service types offered by the second wireless communication network;

a third logic that directs the logic circuit to select one of the first and second wireless communication network based at least in part on the first and second signals.

19. A logic circuit as defined in claim 18, wherein the third logic comprises a logic that directs the logic circuit to select one of the first and second wireless communication networks based at least in part on one or more of the following:

a signal strength of each of the first and second signals;

the most efficient use of communication resources of the first and second wireless communication networks; and

communication service types required by a mobile station.

20. A logic circuit as defined in claim 19, wherein the third logic comprises a logic that directs the logic circuit to select one of the first and second wireless communication networks based at least in part on one or more of the following:

the wireless communication network that provides the closest match between the offered communication services types and the required communication service types; and

communication service types preferred by a user of the mobile station, wherein the required communication service types are the minimum communication service types required by the mobile station.
