METHOD AND DEVICE FOR SMS PROCESSING THROUGH IMS NETWORK

摘要

The present invention relates to a method and device for short message service (SMS) processing through an IP multimedia subsystem (IMS) network. An SMS processing method in an internet protocol-short message-gateway (IP-SM-GW) of the IMS network according to an embodiment of the present invention includes obtaining user information from a serving call session control function (S-CSCF) and a home subscriber server (HSS) and notifying the S-CSCF of an SMS destination by using a globally routable user agent URI (GURR) or a +sip.instance parameter based on the user information. According to the present invention, when there is a shared implicitly registered ID set (IRS) subscriber in the IMS, i.e., even if there are terminals sharing the same public ID and having different private IDs, it is possible to accurately transmit an SMS message to an intended terminal. Also, according to the present invention, it is possible to restore missing data even if the IP-SM-GW has a defect.

1. A method for processing SMS at an IP-SM-GW (Internet Protocol-Short Message-GateWay) in an IMS network, the method comprising steps of:
obtaining user information from at least one of an S-CSCF (Serving Call Session Control Function) and an HSS (Home Subscriber Server); and when the SMS is received, transmitting GRUU (Globally Routable User Agent URI) or +sip.instance parameter to the S-CSCF, based on the user information, wherein the GRUU or the +sip.instance parameter is used when the S-CSCF determines a reception destination of the SMS.
