METHOD AND APPARATUS FOR TRIGGERING AND SYNCHRONIZING MACHINE TYPE COMMUNICATION DEVICES
First Claim
1. A method of triggering and synchronizing a machine type communication (MTC) wireless transmit/receive unit (WTRU), the method comprising:
- providing a reporting cycle, wherein the MTC WTRU attaches to a network to report data at a given interval; and
providing a control cycle, wherein the MTC WTRU attaches to the network at triggered events.

Abstract
Methods and apparatus for triggering and synchronizing a machine type communication (MTC) device are described. MTC devices may operate in a time controlled mode, where the MTC device attaches to a network at specified intervals to report to a network. The time controlled mode may include two time controlled cycles, a reporting cycle and a control cycle. Methods are also described for communicating the reporting and control cycles between the MTC device and the network or MTC server. These cycles may be communicated on an application layer, by an MTC server using an MTCsp interface or via MTC configuration. In addition, triggering cycles may be sent via the Non-Access-Stratum (NAS) layer by extending discontinuous reception (DRX) cycles or by allowing a network to send the cycles over a broadcast channel by defining new System information block (SIB) information.

16. A machine type communication (MTC) wireless transmit/receive unit (WTRU), comprising:
-
a processor; a receiver in communication with the processor; the processor and receiver configured to obtain information indicating at least one control cycle and at least one reporting cycle; the processor and receiver configured to monitor for triggering information on one of a paging channel or a broadcast channel during a control cycle, wherein the MTC WTRU is entering an idle/offline mode; a transmitter in communication with the processor; and the processor, receiver and transmitter configured to establish a connection with an MTC server during a reporting cycle to report information.
