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:

the WTRU transmitting an attach request message via a cellular radio access network (RAN) to a Serving General Packet Radio Service (GPRS) Support Node (SGSN) in a core network,

wherein the attach request message includes a mobile station (MS) radio access capability information element (IE), and

wherein the MS radio access capability IE includes a field that indicates whether the WTRU is capable of receiving services from the core network via a non-cellular wireless access network; and

the WTRU receiving services from the core network.

2. The method of claim 1, wherein the non-cellular wireless access network is a wireless local area network (WLAN).

3. The method of claim 1, wherein the MS radio access capability IE further includes:

an RF Power Capability field;

a Multislot capability field;

an 8PSK Power Capability field;

a COMPACT Interference Measurement Capability field;

a Revision Level Indicator field;

a UMTS FDD Radio Access Technology Capability field;

a UMTS 3.84 Mcps TDD Radio Access Technology Capability field;

a UMTS 1.28 Mcps TDD Radio Access Technology Capability field; and

a Modulation based multislot class support field.

4. The method of claim 1, wherein the cellular radio access network is based on Global System for Mobile Communications (GSM) or Universal Mobile Telecommunications System (UMTS) technology.

5. The method of claim 1, wherein the services are received via the cellular RAN.

6. The method of claim 1, wherein the services are received via a non-cellular wireless access network.

7. The method of claim 1, further comprising:

the WTRU receiving an attach accept message from the SGSN, wherein the attach accept message is responsive to the attach request message.

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

a transmitter configured to transmit an attach request message via a cellular radio access network (RAN) to a Serving General Packet Radio Service (GPRS) Support Node (SGSN) in a core network,

wherein the attach request message includes a mobile station (MS) radio access capability information element (IE), and

wherein the MS radio access capability IE includes a field that indicates whether the WTRU is capable of receiving services from the core network via a non-cellular wireless access network; and

a receiver configured to receive services from the core network.

9. The WTRU of claim 8, wherein the MS radio access capability IE indicates whether the non-cellular wireless access network is a wireless local area network (WLAN).

10. The WTRU of claim 8, wherein the MS radio access capability IE further includes:

an RF Power Capability field;

a Multislot capability field;

an 8PSK Power Capability field;

a COMPACT Interference Measurement Capability field;

a Revision Level Indicator field;

a UMTS FDD Radio Access Technology Capability field;

a UMTS 3.84 Mcps TDD Radio Access Technology Capability field;

a UMTS 1.28 Mcps TDD Radio Access Technology Capability field; and

a Modulation based multislot class support field.

11. The WTRU of claim 8, wherein the cellular RAN is based on Global System for Mobile Communications (GSM) or Universal Mobile Telecommunications System (UMTS) technology.

12. The WTRU of claim 8, wherein the receiver is configured to receive the services via the cellular RAN.

13. The WTRU of claim 8, wherein the receiver is configured to receive the services via a non-cellular wireless access network.

14. The WTRU of claim 8, wherein the receiver is further configured to receive an attach accept message from the SGSN, wherein the attach accept message is responsive to the attach request message.

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

the WTRU performing an attach procedure to attach to a Serving General Packet Radio Service (GPRS) Support Node (SGSN) in a core network, wherein the attach procedure includes;

the WTRU transmitting an attach request message to the SGSN,

wherein the attach request message includes a mobile station (MS) radio access capability information element (IE), and

wherein the MS radio access capability IE includes a field that indicates whether the WTRU is capable of receiving services from the core network via a non-cellular wireless access network; and

the WTRU receiving an attach accept message from the SGSN.

16. The method of claim 15, wherein the non-cellular wireless access network is a wireless local area network (WLAN).

17. The method of claim 15, wherein the MS radio access capability IE further includes:

an RF Power Capability field;

a Multislot capability field;

an 8PSK Power Capability field;

a COMPACT Interference Measurement Capability field;

a Revision Level Indicator field;

a UMTS FDD Radio Access Technology Capability field;

a Modulation based multislot class support field.

18. The method of claim 15, wherein the cellular radio access network is based on Global System for Mobile Communications (GSM) or Universal Mobile Telecommunications System (UMTS) technology.

19. The method of claim 15, further comprising:

the WTRU receiving services from the core network via a cellular radio access network (RAN).

20. The method of claim 15, further comprising:

the WTRU receiving services from the core network via a non-cellular wireless access network.
