Apparatus and method for delivering short message service efficiently in wireless communication system
First Claim
1. A method for short message service (SMS) by a core network (CN) node in a wireless communication system, the method comprising:
- receiving, from a terminal, an attach request message including information indicating that the terminal requests SMS;
transmitting, to a home subscriber server (HSS), a location update request message including information indicating that the CN node is capable of SMS transfer without establishing an association with a mobile switching center (MSC);
receiving, from the HSS, a location update answer message including information indicating whether the CN node is registered for the SMS; and
transmitting, to the terminal, an attach accept message including information indicating that an attach of the terminal is for the SMS if the SMS in the CN node is provided.

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.
