1. A method for use in a network node, the method comprising:
- receiving an indication that a wireless transmit/receive unit (WTRU) is registered with an Internet Protocol (IP)-Short Message (SM) gateway to receive SMs via an IP multimedia subsystem (IMS);
storing an address of the IP-SM gateway serving the WTRU;
receiving a request for routing information for the WTRU; and
transmitting the address of the IP-SM gateway serving the WTRU in response to the request for routing information for the WTRU.

Abstract
A method and system for reporting short message (SM) capability over an IP multimedia subsystem (IMS) using a session initiation protocol (SIP) are disclosed. A wireless transmit/receive unit (WTRU) registers with a core network and sends a message indicating its SM capability via the IMS to the core network. The core network then updates the WTRU capabilities based on the message and routes an SM to the WTRU via the IMS.
