Abstract

A method and system for reporting short message (SM) capability over an IP multimedia subsystem (IMS) using a session initiation protocol (SIP) are disclosed. A wireless transmit/receive unit (WTRU) registers with a core network and sends a message indicating its SM capability via the IMS to the core network. The core network then updates the WTRU capabilities based on the message and routes an SM to the WTRU via the IMS.

Claims

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

the WTRU connecting to a radio access network (RAN);

the WTRU registering with a core network via the RAN;

the WTRU sending a first message including a network capability information element (IE) to the core network using session initiation protocol (SIP), the network capability indicating a capability of the WTRU to receive Short Message Service (SMS) messages via an Internet Protocol multimedia subsystem (IMS); and

the WTRU receiving a SMS message via the IMS using SIP.

2. The method of claim 1 wherein the network capability IE indicates capability of transmitting and receiving at least one of a SMS message, a multimedia message service (MMS) message, and an instant message service message via the IMS.

3. The method of claim 1 further comprising:

receiving a second message, the second message reporting a capability of the core network to support a SMS via the IMS.

4. The method of claim 1 wherein the RAN is a third generation (3G) RAN.

5. The method of claim 1 wherein the RAN is an interworking wireless local area network (I-WLAN).

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

a processor, configured to generate a first message including a network capability information element (IE), the network capability IE indicating a capability of the WTRU to receive Short Message Service (SMS) via an Internet Protocol multimedia subsystem (IMS);

a transmitter, configured to send the first message including the network capability IE to a core network using session initiation protocol (SIP) and to register the WTRU with the core network via a radio access network (RAN); and

a receiver, configured to receive a SMS message via the IMS using SIP.

7. The WTRU of claim 6 wherein the RAN is a third generation (3G) RAN.

8. The WTRU of claim 6 wherein the RAN is an interworking wireless local area network (I-WLAN).

9. The WTRU of claim 6 wherein the network capability IE indicates capability of transmitting and receiving at least one of a SMS message, a multimedia message service (MMS) message, and an instant message service message via the IMS.

10. The WTRU of claim 6 wherein the receiver is further configured to receive a second message, the second message reporting a capability of the core network to support a SMS via the IMS.
