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. A wireless network comprising:

an Internet Protocol short message gateway (IP-SM-GW) configured to receive capability information from a call session control function (CSCF), the capability information being associated with Short Message Service (SMS) capability of a user equipment (UE);

the IP-SM-GW further configured to send a first Session Initiation Protocol (SIP) to the CSCF, the first SIP message including an SMS message; and

the CSCF configured to send the first SIP message to the UE;

the CSCF further configured to receive a second SIP message from the UE, wherein the second SIP message is a SIP OK message and wherein the second SIP message is responsive to the first SIP message.

2. The wireless network of claim 1, wherein the capability information indicates that the UE is capable of receiving SMS using SIP.

3. The wireless network of claim 1, wherein the first SIP message is sent to the UE via a Wireless Local Area Network (WLAN) and wherein the second SIP message is received from the UE via the WLAN.

4. The wireless network of claim 1, wherein the CSCF is further configured to receive a third SIP message from the UE, the third SIP message including a delivery report associated with the SMS message.

5. The wireless network of claim 4, wherein the CSCF is further configured to send the third SIP message to the IP-SM-GW.

6. The wireless network of claim 1, wherein the CSCF is further configured to register the UE according to an Internet Protocol (IP) multimedia subsystem (IMS) registration procedure.

7. The wireless network of claim 1, wherein the CSCF is further configured to apply filtering to a received message.

8. A method, implemented in a wireless network, the method comprising:

receiving, by an Internet Protocol short message gateway (IP-SM-GW), capability information from a call session control function (CSCF), the capability information being associated with Short Message Service (SMS) capability of a user equipment (UE);

sending, by the IP-SM-GW, a first Session Initiation Protocol (SIP) to the CSCF, the first SIP message including an SMS message; and

sending, by the CSCF, the first SIP message to the UE;

receiving, by the CSCF, a second SIP message from the UE, wherein the second SIP message is a SIP OK message and wherein the second SIP message is responsive to the first SIP message.

9. The method of claim 8, wherein the capability information indicates that the UE is capable of receiving SMS using SIP.

10. The method of claim 8, wherein the first SIP message is sent to the UE via a Wireless Local Area Network (WLAN) and wherein the second SIP message is received from the UE via the WLAN.

11. The method of claim 8, further comprising:

receiving, by the CSCF, a third SIP message from the UE, the third SIP message including a delivery report associated with the SMS message.

12. The method of claim 11, further comprising:

sending, by the CSCF, the third SIP message to the IP-SM-GW.

13. The method of claim 8, further comprising:

register, by the CSCF, the UE according to an Internet Protocol (IP) multimedia subsystem (IMS) registration procedure.

14. The method of claim 8, further comprising:

applying, by the CSCF, filtering to a received message.
