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 network node, the method comprising:
receiving information related to short message service (SMS) capabilities of a user equipment (UE);
receiving SMS data intended for the UE;
determining whether to deliver the SMS data to the UE; and
in response to a determination to deliver the SMS data to the UE, sending a Session Initiation Protocol (SIP) message that includes the SMS data to the UE.
2. The method of claim 1 , wherein the determining whether to deliver the SMS data to the UE is performed based on the information related to SMS capabilities of the UE.
3. The method of claim 1 , wherein the SIP message is sent to the UE via a Call State Control Function (CSCF).
4. The method of claim 1 , wherein the SMS data is received using Signaling System #7 (SS 7 ).
5. The method of claim 1 , further including:
generating the SIP message based on a Mobile Subscriber Integrated Services Digital Network Number (MSISDN) of the UE included in the SMS data.
6. The method of claim 1 , wherein the SIP message includes a Request URI field that includes a TEL-URL associated with the UE.
7. The method of claim 1 , wherein the network node is a wherein the network node is an Internet Protocol Short Message Gateway (IP-SM-GW).
8. A network node comprising:
a communications interface configured to:
receive information related to short message service (SMS) capabilities of a user equipment (UE);
receive SMS data intended for the UE; and
a processor configured to determine whether to deliver the SMS data to the UE;
wherein the communications interface is configured to send a Session Initiation Protocol (SIP) message that includes the SMS data to the UE in response to a determination to deliver the SMS data to the UE.
9. The network node of claim 8 , wherein the processor is configured to determine whether to deliver the SMS data to the UE based on the information related to SMS capabilities of the UE.
10. The network node of claim 8 , wherein the communications interface is configured to send the SIP message to the UE via a Call State Control Function (CSCF).
11. The network node of claim 8 , wherein the communications interface is configured to receive the SMS data using Signaling System #7 (SS 7 ).
12. The network node of claim 8 , wherein the processor is configured to generate the SIP message based on a Mobile Subscriber Integrated Services Digital Network Number (MSISDN) of the UE included in the SMS data.
13. The network node of claim 8 , wherein the SIP message includes a Request URI field that includes a TEL-URL associated with the UE.
14. The network node of claim 8 , wherein the network node is an Internet Protocol Short Message Gateway (IP-SM-GW).
15. A method for use in a user equipment (UE), the method comprising:
registering with a serving call state control function (S-CSCF) in a network using an Internet Protocol Multimedia Subsystem (IMS) registration procedure;
sending information to the network, the information related to short message service (SMS) message capabilities of the UE; and
receiving Short Message Service (SMS) data using Session Initiation Protocol (SIP) via a Internet Protocol short message gateway (IP-SM-GW) and the S-CSCF.
16. The method of claim 15 , further comprising:
sending a SMS message to a second UE using SIP via the IP-SM-GW and the S-CSCF.
17. The method of claim 15 , wherein the information related to short message service (SMS) message capabilities of the UE indicates that the UE supports SIP.
