Method and system for reporting a short message capability via an IP multimedia subsystem
A method performed by a WTRU may comprise transmitting a request for attachment to a base station. Authentication may be performed between the WTRU and a cellular core network node of a cellular core network, via the base station. The method may further comprise transmitting a registration request to the cellular core network via SIP over an IMS and transmitting a SIP message indicating a capability of the WTRU to receive data messages via the IMS. The WTRU may receive, in accordance with the capability of the WTRU to receive data messages via the IMS, at least one data message, from the base station, via the IMS. The data message may be displayed on a display of the WTRU.
1. A wireless transmit/receive unit (WTRU) comprising:
a transmitter configured to transmit, to a base station, a request for attachment;
circuitry configured to authenticate with a cellular core network node of a cellular core network via the base station;

the transmitter configured to transmit a SIP message indicating a capability of the WTRU to receive data messages via the IMS;
a receiver configured to receive, in accordance with the capability of the WTRU to receive data messages via the IMS, at least one data message, from the base station, via the IMS; and
a display configured to display the at least one data message.
2. The WTRU of claim 1 , wherein the data message is ciphered prior to reception by the WTRU.
3. The WTRU of claim 1 , wherein the base station is a wireless local area network (WLAN) base station.
4. The WTRU of claim 1 , wherein the data message is an instant message.
5. The WTRU of claim 1 , wherein the data message is a short message service (SMS) data message.
6. The WTRU of claim 2 , further comprising:
circuitry configured to decipher the ciphered data message.
7. The WTRU of claim 1 , wherein the data message is a video data message.
8. The WTRU of claim 7 , wherein the video data message is a text plus video data message.
9. A method performed by a wireless transmit/receive unit (WTRU), the method comprising:
transmitting, to a base station, a request for attachment;
authenticating with a cellular core network node of a cellular core network via the base station;
transmitting a registration request to the cellular core network via session initiation protocol (SIP) over an Internet Protocol multimedia subsystem (IMS);
transmitting a SIP message indicating a capability of the WTRU to receive data messages via the IMS;
receiving, in accordance with the capability of the WTRU to receive data messages via the IMS, at least one data message, from the base station, via the IMS; and
displaying the at least one data message.
10. The method of claim 9 , wherein the indicated capability of the WTRU to receive data messages via the IMS is a capability of the WTRU to receive instant messages via the IMS.
11. The method of claim 9 , wherein the at least one data message includes video data.
12. The method of claim 11 , wherein the at least one data message is an instant message.
13. A wireless transmit/receive unit (WTRU) comprising:
a transmitter configured to transmit, to a base station, a request for attachment;
circuitry configured to authenticate with a cellular core network node of a cellular core network via the base station;
the transmitter configured to transmit a registration request to the cellular core network via session initiation protocol (SIP) over an Internet Protocol multimedia subsystem (IMS);
the transmitter configured to transmit a SIP message indicating a capability of the WTRU to transmit and receive data messages via the IMS;
the transmitter configured to transmit, in accordance with the indicated capability of the WTRU, a first data message, to the base station, via the IMS;
a receiver configured to receive, in accordance with the indicated capability of the WTRU, a second data message, from the base station, via the IMS; and
a display configured to display the first data message and the second data message.
14. The WTRU of claim 13 , wherein the first data message includes video data and text data.
15. The WTRU of claim 13 , wherein the at least one data message is an instant message.
16. The WTRU of claim 13 , wherein the base station is a wireless local area network (WLAN) base station.
