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.
Claims10
An integrated circuit (IC) comprising:
- circuitry configured to provide a signal for connecting to a radio access network (RAN);
- the circuitry is further configured to provide a signal for registering a wireless transmit/receive unit (WTRU) with a core network via the RAN;
- the circuitry is further configured to provide a signal indicating a first message including a network capability information element (IE) to the core network using session initiation protocol (SIP), the network capability indicating a capability of the WTRU to receive Short Message Service (SMS) messages via an Internet Protocol multimedia subsystem (IMS);
- and
- the circuitry is further configured to receive a signal associated with an SMS message via the IMS using SIP.
