Abstract:
1. A method of transmitting data in a wireless communication system, the method performed by a machine type communication (MTC) device and comprising: transmitting a first tracking area update (TAU) request message via radio resource control (RRC) signaling; receiving, in response to the first TAU request message, a first TAU accept message via RRC signaling, wherein the first TAU accept message includes an MTC device triggering indication which is generated by and transmitted from an MTC server; starting a random access procedure when there is an uplink data associated with the MTC device triggering indication; after starting the random access procedure, transmitting a second TAU request message via RRC signaling; receiving, in response to the second TAU request message, a second TAU accept message via RRC signaling; and transmitting, in response to the second TAU accept message, a TAU complete message together with the uplink data via RRC signaling.
