Abstract

Method and apparatus for enabling a wireless terminal to communicate the dual-mode capabilities and reporting the interworking capabilities of the two networks with which the wireless terminal have the added capability of obtaining services from either one of the interworking networks.

Claims

1. A method for use in a wireless transmit/receive unit (WTRU), the method comprising:

generating an attach request message that indicates a request to attach to a cellular core network and that includes a capability indicator that indicates whether the WTRU is capable of receiving services from the cellular core network via a wireless local area network (WLAN);

communicating the attach request message to a network node in the cellular core network; and

receiving services via the network node based on the capability indicator.

2. The method of claim 1, wherein the services are received via a cellular radio access network.

3. The method of claim 2, wherein the cellular radio access network is based on GSM or UMTS technology.

4. The method of claim 1, wherein the capability indicator is a radio access capability information element or a mobile station (MS) network capability information element.

5. The method of claim 1, wherein the services are received via a wireless local area network (WLAN).

6. The method of claim 5, further comprising:

receiving a Short Message Service (SMS) message via the WLAN.

7. The method of claim 1, further comprising:

receiving an acknowledgement of the attach request message from the network node.

8. A wireless transmit/receive unit (WTRU) comprising:

a processor configured to generate an attach request message that indicates a request to attach to a cellular core network and that includes a capability indicator that indicates whether the WTRU is capable of receiving services from the cellular core network via a wireless local area network (WLAN);

a transmitter configured to transmit the attach request message to a network node in the cellular core network; and

a receiver configured to receive services via the network node based on the capability indicator.

9. The WTRU of claim 8, wherein the receiver is configured to receive the services via a cellular radio access network.

10. The WTRU of claim 9, wherein the cellular radio access network is based on GSM or UMTS technology.

11. The WTRU of claim 8, wherein the capability indicator is a radio access capability information element or a mobile station (MS) network capability information element.

12. The WTRU of claim 8, wherein the services are received via a WLAN.

13. The WTRU of claim 12 wherein the receiver is further configured to receive a Short Message Service (SMS) message via the WLAN.

14. The WTRU of claim 8, wherein the receiver is further configured to receive an acknowledgement of the attach request message from the network node.
