Method and apparatus are described for delivering triggers and small data. In an embodiment, a receiver may be configured to receive a trigger or small data packet, and a transmitter may be configured to transmit a subscriber information request to see whether a subscriber is present. The receiver may be further configured to receive an identity of a second node on a condition that the subscriber is present. The transmitter may be further configured to transmit the trigger or small data packet to the second node over an interface, the second node configured to create an Internet Protocol (IP) packet with an IP address containing the trigger or small data packet and deliver the IP packet to a wireless transmit/receive unit (WTRU) using the IP address and a default or dedicated bearer of the WTRU.
