1. A base station configured to:
- receive a request for attachment from a wireless transmit/receive unit (WTRU);
transmit and receive authentication messages between the WTRU and a cellular core network node, wherein the cellular core network includes a home location register (HLR);
receive a registration request from the WTRU via session initiation protocol (SIP), wherein the registration request indicates a capability of the WTRU to receive Short Message Service (SMS) messages via an Internet Protocol multimedia subsystem (IMS); and
transmit, in accordance with the capability of the WTRU, at least one message comprising SMS data, to the WTRU, via the IMS via SIP;
wherein the SMS data is ciphered prior to transmission to the WTRU.

Abstract
A method and apparatus for operation by a base station are provided. The base station may be configured to receive a request for attachment from a WTRU and transmit and receive authentication messages between the WTRU and a cellular core network including an HLR. A registration request may be received from the WTRU via SIP, the registration request indicating a capability of the WTRU to receive SMS messages via an IMS. In accordance with the capability of the WTRU, at least one message comprising SMS data may be transmitted, to the WTRU, via the IMS using SIP. The capability of the WTRU may be recorded by the HLR and the SMS data may be ciphered prior to transmission to the WTRU.
