Reporting terminal capabilities for supporting short message service
A method for delivering a short message service (SMS) message to an interworking wireless local area network user equipment (UE) begins by registering the UE with an Internet Protocol short message gateway (IP-SM-GW). A capability report is sent from the UE to the IP-SM-GW, the capability report including the capabilities of the UE. A SMS message is transmitted from a short message service center (SMSC) to the IP-SM-GW. The capabilities of the UE are evaluated at the IP-SM-GW to determine whether the UE can receive the SMS message, and the SMS message is delivered to the UE via the IP-SM-GW if the UE has the capabilities to receive the SMS message.
1. A method for use in a user equipment (UE), the method comprising:
the UE transmitting capability information via a wireless network, wherein the capability information indicates short message service (SMS) capabilities of the UE;
the UE receiving a first Session Initiation Protocol (SIP) message via the wireless network and one or more IP Multimedia Subsystem (IMS) servers, wherein the first SIP message includes a Short Message Service (SMS) message; and
the UE transmitting a second SIP message via the wireless network and the one or more IMS servers, wherein
the second SIP message is a SIP OK message, and
the second SIP message is responsive to the first SIP message.
2. The method of claim 1 , wherein the one or more IMS servers include an Internet Protocol Short Message Gateway (IP-SM-GW).
3. The method of claim 1 , wherein the one or more IMS servers include a Call State Control Function (CSCF).
4. The method of claim 1 wherein the capability information indicates that the UE is capable of receiving SMS using SIP.
5. The method of claim 1 , wherein the wireless network is a Wireless Local Area Network (WLAN).
6. The method of claim 1 , further comprising:
the UE transmitting a third SIP message via the wireless network and the one or more IMS servers, wherein the third SIP message includes a delivery report related to the SMS message.
7. A user equipment (UE) comprising:
a transmitter configured to transmit capability information via a wireless network, wherein the capability information indicates short message service (SMS) capabilities of the UE;
a receiver configured to receive a first Session Initiation Protocol (SIP) message via the wireless network and one or more IP Multimedia Subsystem (IMS) servers, wherein the first SIP message includes a Short Message Service (SMS) message;
wherein the transmitter is further configured to transmit a second SIP message via the wireless network and the one or more IMS servers, wherein
the second SIP message is a SIP OK message, and
the second SIP message is responsive to the first SIP message.
8. The UE of claim 7 , wherein the one or more IMS servers include an Internet Protocol Short Message Gateway (IP-SM-GW).
9. The UE of claim 7 , wherein the one or more IMS servers include a Call State Control Function (CSCF).
10. The UE of claim 7 wherein the capability information indicates that the UE is capable of receiving SMS using SIP.
11. The UE of claim 7 , wherein the wireless network is a Wireless Local Area Network (WLAN).
12. The UE of claim 7 , wherein the transmitter is further configured to transmit a third SIP message via the wireless network and the one or more IMS servers, wherein the third SIP message includes a delivery report related to the SMS message.
13. A method for use in a user equipment (UE), the method comprising:
the UE transmitting capability information via a wireless network, wherein the capability information indicates short message service (SMS) capabilities of the UE;
the UE transmitting a first Session Initiation Protocol (SIP) message via the wireless network and one or more IP Multimedia Subsystem (IMS) servers, wherein the first SIP message includes a Short Message Service (SMS) message; and
the UE receiving a second SIP message via the one or more IMS servers and the wireless network, wherein
the second SIP message is a SIP Accepted message, and
the second SIP message is responsive to the first SIP message.
14. The method of claim 13 , wherein the one or more IMS servers include an Internet Protocol Short Message Gateway (IP-SM-GW).
15. The method of claim 13 , wherein the one or more IMS servers include a Call State Control Function (CSCF).
16. The method of claim 13 , wherein the capability information indicates that the UE is capable of receiving SMS using SIP.
17. The method of claim 13 , wherein the wireless network is a Wireless Local Area Network (WLAN).
18. The method of claim 13 further comprising:
the UE receiving a third SIP message via the one or more IMS servers and the wireless network, wherein the third SIP message includes a submit report related to the SMS message.
