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 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.
