Abstract

A system and method for facilitating network-to-network transitions of mobile stations comprising includes at least one access point ( 204 ). At least one receiver ( 202, 224 or 230 ) is coupled to the at least one access point. The at least one receiver ( 202, 224 or 230 ) determines information concerning a wide area network and provides the information to the access point ( 204 ). The access point ( 204 ) conveys the information to at least one mobile station ( 206 ).

Claims (25)

1. A system far facilitating network-to-network transitions of mobile stations comprising:

a first receiver to provide access to a wireless local area network, wherein the first receiver is located at an access point of the wireless local area network; and

at least one second receiver physically coupled to the first receiver, wherein the at least one second receiver is located at the access point and determines information concerning a wide area network and provides the information to the access point, and wherein the access point conveys the information to at least one mobile station, wherein the at least one mobile station is separate from the first receiver.

2. The system of claim 1 wherein the access point is located near a. transition region to the wide area network.

3. The system of claim 1 wherein the at least one mobile station comprises means for determining a preferred service provider from the information received from the at least one access point.

4. The system of claim 1 wherein the wide area network is chosen from a group comprising a code division multiple access (CDMA) network, a global system for mobile communications (GSM) network, a Universal Mobile Telecommunications System (UMTS) network, advanced mobile phone service (AMPS) network, and a time division multiple access (TDMA) network.

5. A method for facilitating network-to-network transitions of mobile stations comprising:

scanning for and receiving information received from a wide area network receiver located at an access point of a wireless local area network, wherein the information concerning at least one characteristic of a wide area network to provide received information;

supplying the received information to a wireless local area network receiver located at the access point and wherein the wireless local area network receiver being physically coupled to the wide are network receiver; and

forwarding information that corresponds to the received information from the access point to at least one mobile station, wherein the at least one mobile station is separate from the wide area network receiver.

6. The method of claim 5 further comprising determining a strength measurement report at the access point and sending information that corresponds to the report to the at least one mobile station.

7. The method of claim 5 wherein scanning and receiving the information comprises scanning for the presence of a cellular network by decoding system information messages.

8. The method of claim 5 wherein scanning and receiving information comprises receiving information indicative of an available radio access technology (RAT) and available communication channels.

9. The method of claim 5 further comprising receiving the information at the at least one mobile station and transitioning to a wide area network determined at least in part based upon the information.

10. The method of claim 9 wherein transitioning from the service provider to a wide area network comprises transitioning to a network chosen from a group consisting of a code division multiple access (CDMA) network, a global system for mobile communications (GSM) network, a Universal Mobile Telecommunications System (UMTS) network, an advanced mobile phone service (AMPS) network, and a time division multiple access (TDMA) network.

11. A method of transitioning from a wireless local area network to a wide area network comprising:

receiving information from a wide area network receiver, wherein the information concerning at least one characteristic of the wide area network wherein the wide area network receiver located at an access point, to provide received information to a wireless local area network receiver located at the access point wherein the wide are network receiver being physically coupled to the wireless local are network receiver;

determining a service option from the received information; and

supplying the service option to at least one mobile station, wherein the at least one mobile station being separate from the wide area network receiver.

12. The method of claim 11 wherein receiving the information comprises receiving information indicative of an available radio access technology (RAT) available and an available communication channel.

13. The method of claim 11 wherein receiving the information includes receiving WAN system message content from the access point for the RAT of interest.

14. The method of claim 11 wherein receiving the information from an access point includes receiving the information from an access point at an edge of a transition region to a wide area network.

15. The method of claim 11 wherein receiving the information includes receiving a signal strength report from the access point.

16. The method of claim 11 further comprising transitioning from a wireless local area network to a wide area network based at least in part upon the received information.

17. The method of claim 16 wherein transitioning from the service provider to a wide area network comprises transitioning to a network chosen from a group consisting of a code division multiple access (CDMA) network, a global system for mobile communications (GSM) network, a Universal Mobile Telecommunications System (UMTS) network, an advanced mobile phone service (AMPS) network, and a time division multiple access (TDMA) network.
