Method and system for reporting a short message capability via an IP multimedia subsystem
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 short message Internet Protocol gateway (SM-IP-GW) receives a registration request via session initiation protocol (SIP). The registration request may indicate a capability of a WTRU to receive Short Message Service (SMS) messages via an Internet Protocol multimedia subsystem (IMS). The SM-IP-GW transmits a successful registration message to a home location register (HLR) to indicate that a WTRU has successfully registered with the SM-IP-GW. Once the HLR is informed that a WTRU is successfully registered with the SM-IP-GW, SMS messages may be received and transmitted via the IMS using SIP.
1. A method performed by a short message Internet Protocol gateway (SM-IP-GW), the method comprising:
receiving a registration request, at the SM-IP-GW from a wireless transmit/receive unit (WTRU) via session initiation protocol (SIP), wherein the registration request indicates a capability of the WTRU to receive Short Message Service (SMS) messages via an Internet Protocol multimedia subsystem (IMS);
transmitting a successful registration message, from the SM-IP-GW to a home location register (HLR), wherein the successful registration message indicates that the WTRU has successfully registered with the SM-IP-GW; and
receiving a message comprising SMS data, at the SM-IP-GW from the WTRU, via the IMS using SIP.
2. The method of claim 1 , wherein the message comprising SMS data is a multimedia message service (MMS) message.
3. The method of claim 1 , wherein the message comprising SMS data is an instant message service message.
4. The method of claim 1 , wherein the registration request is received over an interworking wireless local area network (I-WLAN).
5. A method performed by a short message Internet Protocol gateway (SM-IP-GW), the method comprising:
receiving a registration request, at the SM-IP-GW from a wireless transmit/receive unit (WTRU) via session initiation protocol (SIP), wherein the registration request indicates a capability of the WTRU to receive Short Message Service (SMS) messages via an Internet Protocol multimedia subsystem (IMS);
transmitting a successful registration message, from the SM-IP-GW to a home location register (HLR), wherein the successful registration message indicates that the WTRU has successfully registered with the SM-IP-GW; and
transmitting a message comprising SMS data, from the SM-IP-GW to the WTRU, via the IMS using SIP.
6. The method of claim 5 , wherein the message comprising SMS data is a multimedia message service (MMS) message.
7. The method of claim 5 , wherein the message comprising SMS data is an instant message service message.
8. The method of claim 5 , wherein the registration request is received over an interworking wireless local area network (I-WLAN).
9. A short message Internet Protocol gateway (SM-IP-GW) comprising:
a receiver configured to receive a registration request, at the SM-IP-GW from a wireless transmit/receive unit (WTRU) via session initiation protocol (SIP), wherein the registration request indicates a capability of the WTRU to receive Short Message Service (SMS) messages via an Internet Protocol multimedia subsystem (IMS); and
a transmitter configured to transmit a successful registration message, from the SM-IP-GW to a home location register (HLR), wherein the successful registration message indicates that the WTRU has successfully registered with the SM-IP-GW;
wherein the transmitter is further configured to transmit a message comprising SMS data, from the SM-IP-GW to the WTRU, via the IMS using SIP.
10. The SM-IP-GW of claim 9 , wherein the message comprising SMS data is a multimedia message service (MMS) message.
11. The SM-IP-GW of claim 9 , wherein the message comprising SMS data is an instant message service message.
12. The SM-IP-GW of claim 9 , wherein the registration request is received over an interworking wireless local area network (I-WLAN).
13. The SM-IP-GW of claim 9 , wherein the receiver is further configured to receive a message comprising SMS data, at the SM-IP-GW from the WTRU, via the IMS using SIP.
