Abstract

A multiple wireless access technology capable (WAT-capable) wireless transmit receive unit (WTRU) includes a registration message generator configured to generate a registration message indicating that the WTRU is configured to communicate using an IEEE 802.11x technology. The WTRU also includes a transmitter configured to send the registration message via an IEEE 802.11x WLAN to a cellular network during registration with the cellular network, and a receiver configured to receive services from the cellular network via the WLAN. The registration message further indicates that the WTRU is configured to receive Short Message Service (SMS) messages from the cellular network via the WLAN. The WTRU receiver receives services that include Short Message Service (SMS) messages.

Claims

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

a transmitter configured to transmit, to a wireless local area network (WLAN), a registration message for delivery to a cellular network using Internet Protocol (IP);

wherein the registration message includes a first indication of an access network of the WLAN and a second indication, wherein the second indication indicates that the WTRU supports short message service (SMS) messaging via the WLAN; and

a receiver configured to receive a data message from the WLAN based on the registration message, wherein the data message includes SMS message data and the data message is received via the cellular network;

wherein the registration message further includes a third indication, wherein the third indication indicates that the WTRU supports Voice over IP (VoIP).

2. The WTRU of claim 1 wherein the WTRU supports multiple wireless access technologies including at least WLAN and cellular.

3. A method used by a wireless transmit/receive unit (WTRU), the method comprising:

transmitting, by a wireless transmit receive unit (WTRU), to a wireless local area network (WLAN), a registration message for delivery to a cellular network using Internet Protocol (IP);

wherein the registration message includes a first indication of an access network of the WLAN and a second indication, wherein the second indication indicates that the WTRU supports short message service (SMS) messaging via the WLAN; and

receiving, by the WTRU, a data message from the WLAN based on the registration message, wherein the data message includes SMS message data and the data message is received via the cellular network;

wherein the registration message further includes a third indication, wherein the third indication indicates that the WTRU supports Voice over IP (VoIP).

4. The method of claim 3 wherein the WTRU supports multiple wireless access technologies including at least WLAN and cellular.

5. A cellular network device comprising:

a receiver configured to receive, from a wireless transmit/receive unit (WTRU) via a wireless local area network (WLAN), a registration message for a cellular network using Internet Protocol (IP);

wherein the registration message includes a first indication of an access network of the WLAN and a second indication, wherein the second indication indicates that the WTRU supports short message service (SMS) messaging via the WLAN; and

a transmitter configured to send a data message to the WTRU via the WLAN based on the registration message, wherein the data message includes SMS message data;

wherein the registration message further includes a third indication, wherein the third indication indicates that the WTRU supports Voice over IP (VoIP).

6. The cellular network device of claim 5 wherein the WTRU supports multiple wireless access technologies including at least WLAN and cellular.

7. The cellular network device of claim 5 wherein the registration message is encrypted.

8. The cellular network device of claim 5 wherein the registration message indicates a type field corresponding to a type of the WTRU.
