Abstract

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.

Claims

1-15. -15. (canceled)

16. 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.

17. The method of claim 16, wherein the one or more IMS servers include an Internet Protocol Short Message Gateway (IP-SM-GW).

18. The method of claim 16, wherein the one or more IMS servers include a Call State Control Function (CSCF).

19. The method of claim 16 wherein the capability information indicates that the UE is capable of receiving SMS using SIP.

20. The method of claim 16, wherein the wireless network is a Wireless Local Area Network (WLAN).

21. The method of claim 16, 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.

22. 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.

23. The UE of claim 22, wherein the one or more IMS servers include an Internet Protocol Short Message Gateway (IP-SM-GW).

24. The UE of claim 22, wherein the one or more IMS servers include a Call State Control Function (CSCF).

25. The UE of claim 22 wherein the capability information indicates that the UE is capable of receiving SMS using SIP.

26. The UE of claim 22, wherein the wireless network is a Wireless Local Area Network (WLAN).

27. The UE of claim 22, 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.

28. 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.

29. The method of claim 28, wherein the one or more IMS servers include an Internet Protocol Short Message Gateway (IP-SM-GW).

30. The method of claim 28, wherein the one or more IMS servers include a Call State Control Function (CSCF).

31. The method of claim 28, wherein the capability information indicates that the UE is capable of receiving SMS using SIP.

32. The method of claim 28, wherein the wireless network is a Wireless Local Area Network (WLAN).

33. The method of claim 28 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.
