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. An integrated circuit (IC) comprising:

circuitry configured to provide a signal for connecting to a radio access network (RAN);

the circuitry is further configured to provide a signal for registering a wireless transmit/receive unit (WTRU) with a core network via the RAN;

the circuitry is further configured to provide a signal indicating 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 circuitry is further configured to receive a signal associated with an SMS message via the IMS using SIP.

2. The IC 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 IC of claim 1 further comprising:

the circuitry further configured to receive a second signal associated with a second message reporting a capability of the core network to support a SMS via the IMS.

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

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

6. A method performed by an integrated circuit (IC), the method comprising:

providing a signal for connecting to a radio access network (RAN);

providing a signal for registering a wireless transmit/receive unit (WTRU) with a core network via the RAN;

providing a signal indicating 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

receiving a signal associated with an SMS message via the IMS using SIP.

7. The method 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.

8. The method of claim 6 further comprising:

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

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

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