DEVICE INITIATED TRIGGERS

摘要

Embodiments contemplate wireless communication that may include sending machine type communication (MTC) application data from a services capability server (SCS) to an MTC user equipment (UE/WTRU) using a device trigger. The device trigger may be used to instruct an MTC device application to initiate communications with an SCS. Embodiments also contemplate that a first device trigger (DT) request may be received from a first wireless transmit/receive unit (WTRU) and a machine-type-communication inter-working function (MTC-IWF) may be determined in response to the first DT request. A second DT request may be sent to the MTC-IWF; and a first DT response may be received from the MTC-IWF. The first DT response may include a first information regarding a second WTRU.

主权项

1. A method for communicating a device trigger performed by a node in communication with a wireless communication network, the method comprising:
receiving a first device trigger (DT) request from a first wireless transmit/receive unit (WTRU), the first DT request including an Internet Protocol (IP) address of the first WTRU and a trigger reference number; determining a machine-type-communication inter-working function (MTC-IWF) in response to the first DT request; sending a second DT request to the MTC-IWF, the second DT request including the Internet Protocol (IP) address of the first WTRU and the trigger reference number; receiving a first DT response from the MTC-IWF, the first DT response including an Internet Protocol (IP) address of a second WTRU and the trigger reference number; and sending a second DT response to the first WTRU, the second DT response including the Internet Protocol (IP) address of a second WTRU and the trigger reference number.
