Abstract

One illustrative method of providing network broadcast information to a wireless device from a wireless local area network (WLAN) includes the steps of receiving, from one or more available cellular networks or a network database, cellular network broadcast information associated with the one or more available cellular networks; providing the cellular network broadcast information in a generic container message which varies in content and format according to one or more cellular standards associated with the one or more available cellular networks; and causing the generic container message to be regularly broadcasted for receipt and use by a wireless device. In an alternative approach, the steps include regularly broadcasting a network interworking indicator which is indicative of whether cellular network broadcast information is available for receipt from the WLAN; receiving a probe request from a wireless device; and causing the cellular network broadcast information to be sent to the wireless device in the generic container message in response to the probe request from the wireless device. The generic container message may alternatively or additionally include wireless network broadcast information from different types of wireless networks (e.g. Wi-MAX) which are available to the WLAN.

Claims

1. A method in a wireless local area network (WLAN), the method comprising:

after providing a network interworking indicator to a wireless device, receiving, from the wireless device, a request message for network information which identifies one or more networks, the network interworking indicator indicating support of a capability of the WLAN to receive network information from a cellular network; and

in response to the request message, providing the network information in a container field of a generic container for transmission to the wireless device.

2. The method of claim 1, wherein the generic container is formatted in accordance with at least one of a technology, a standards organization, or a protocol.

3. The method of claim 1, wherein the generic container further includes a length field associated with a data length of the container field.

4. The method of claim 1, wherein the generic container includes a version field which identifies a version of the generic container.

5. The method of claim 1, wherein the container field includes the network information specified in accordance with a standards organization.

6. The method of claim 1, wherein the one or more networks identified by the network information include at least one 3^rd Generation Partnership Project (3GPP) network.

7. The method of claim 1, wherein the network information comprises a Mobile Network Code (MNC) and Mobile Country Code (MCC) which identifies at least one of the one or more networks.

8. The method of claim 1, wherein a format of the generic container is configured according to a standard associated with a type of network.

9. A wireless local area network (WLAN) which is configured to:

after providing a network interworking indicator to a wireless device, receive a message from the wireless device for requesting network information which identifies one or more networks, the network interworking indicator indicating support of a capability of the WLAN to receive network information from a cellular network; and

provide the network information in a container field of a generic container for transmission to the wireless device in response to receiving the message.

10. The WLAN of claim 9, wherein the generic container is formatted in accordance with at least one of:

a technology, a standards organization, or a protocol.

11. The WLAN of claim 9, wherein the generic container further includes a length field associated with a data length of the container field.

12. The WLAN of claim 9, wherein the generic container further includes a version field which identifies a version of the generic container.

13. The WLAN of claim 9, wherein the container field-includes the network information specified in accordance with a standards organization.

14. The WLAN of claim 9, wherein the one or more networks identified by the network information include at least one 3^rd Generation Partnership Project (3GPP) network.

15. The WLAN of claim 9, wherein the network information comprises a Mobile Network Code (MNC) and Mobile Country Code (MCC) which identifies at least one of the one or more networks.

16. The WLAN of claim 9, wherein a format of the generic container is configured according to a standard associated with a type of network.

17. A method for a wireless device in a wireless local area network (WLAN), the method comprising:

receiving a network interworking indicator at the wireless device, the network interworking indicator indicating support of a capability of the WLAN to communicate information received from a cellular network;

in response to the network interworking indicator, sending from the wireless device to the WLAN a request for network information identifying one or more networks;

receiving the network information in response to the request for network information, wherein the network information is provided in a container field of a generic container.

18. The method of claim 17, wherein the generic container is formatted in accordance with at least one of a technology, a standards organization, or a protocol.

19. The method of claim 17, wherein the generic container further includes a length field associated with a data length of the container field.

20. The method of claim 17, wherein the container field includes the network information specified in accordance with a standards organization.

21. The method of claim 17, wherein the generic container further includes a version field which identifies a version of the generic container.

22. The method of claim 17, wherein the one or more networks identified by the network information include at least one 3^rd Generation Partnership Project (3GPP) network.

23. The method of claim 17, wherein the network information comprises a Mobile Network Code (MNC) and Mobile Country Code (MCC) which identifies at least one of the one or more networks.

24. The method of claim 17, wherein a format of the generic container is configured according to a standard associated with a type of network.

25. A wireless device, comprising:

one or more processors configured to;

receive a network interworking indicator indicating support of a capability of a wireless local area network to receive network information from a cellular network;

in response to the network interworking indicator, send from the wireless device to the wireless local area network a request for network information identifying one or more networks;

receive the network information in response to the request for network information, wherein the network information is provided in a container field of a generic container.

26. The wireless device of claim 25, wherein the generic container is formatted in accordance with at least one of a technology, a standards organization, or a protocol.

27. The wireless device of claim 25, wherein the one or more networks identified by the network information include at least one 3^rd Generation Partnership Project (3GPP) network.
