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.

12. The UE according to claim 11, wherein the capability information includes at least one of:

available memory size, terminal type, screen size, and SIP support.

13. A method for delivering a short message service (SMS) message from an Internet Protocol short message gateway (IP-SM-GW) to a user equipment (UE), comprising:

receiving capability information from the UE, the capability information indicating SMS message capabilities of the UE;

evaluating the capability information to determine whether the UE can receive the SMS message; and

delivering the SMS message to the UE using Session Initiation Protocol (SIP) via a call state control function (S-CSCF).

14. The method according to claim 13, wherein the capability information includes at least one of:

available memory size, terminal type, screen size, and SIP support.

15. The method according to claim 13, wherein the SMS message is received from a short message service center (SM-SC).

16. The method according to claim 13, further comprising:

receiving a delivery report from the UE using SIP; and

sending the delivery report to a short message service center (SM-SC).

17. The method according to claim 16, wherein the delivery report indicates whether the SMS message was delivered to the UE.
