First Claim
1. A method for offering short message service (SMS) by a core network (CN) node in a mobile communication system, the method comprising:
- receiving first information indicating that a mobile station requests SMS among circuit switched (CS) domain services from the mobile station;
transmitting an update location message including second information indicating that the CN node supports SMS to a home subscriber server (HSS);
receiving subscription data including third information indicating whether SMS via the CN node is supported from the HSS;
transmitting, when SMS via the CN node is supported based on the third information, an attach accept message including fourth information indicating that SMS via packet switched (PS) domain is supported to the mobile station; and
determining whether to perform a location update based on the third information.

Abstract
A Short Message Service (SMS) delivery method and apparatus is provided for delivering an SMS message efficiently by selecting a network domain to attach to according to the service provided to a Mobile Station (MS) by the mobile operator network. An SMS delivery method of the present invention includes receiving, at a network node, an Attach/Routing Area Update (RAU) Request message including a parameter indicating an attach/update type and SMS-only service, and transmitting, when SMS in a Serving General Packet Radio Service (GPRS) Support Node (SGSN) is supported at the core network node, to the mobile station an Attach Accept message including a parameter indicating that SMS in SGSN is supported. The SMS delivery method of the present invention is capable of delivering SMS message efficiently in the wireless communication system.
