Abstract
Disclosed is a method and system to help avoid performing third-party registration of a UE with an SMS gateway of an IMS, the IMS including a P-CSCF, an S-CSCF, and an HSS. In an example implementation, when registering for service with the IMS, the UE provides UE-capability data to the P-CSCF, the P-CSCF sends the data to the S-CSCF, and the S-CSCF sends the data to the HSS. The S-CSCF does not send the UE-capability data to the SMS gateway. Rather, when the SMS gateway receives a request to send an SMS message to the UE, the SMS gateway queries the HSS to obtain the UE-capability data. Based on the UE-capability data, the SMS gateway makes a determination of whether the UE is capable of receiving SMS messages over IP and routes the SMS message over an appropriate access network based on the determination.
