METHOD AND APPARATUS FOR TRANSMITTING UPLINK DATA ASSOCIATED WITH MTC DEVICE TRIGGER FUNCTION
First Claim
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 transmitted from an MTC server;
starting a random access procedure to transmit 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.

Abstract
A method and apparatus for small packet transmission in response to machine type communication (MTC) device trigger indication are provided. For uplink (UL) transmission of small packet from MTC device in idle state, a tracking area update (TAU) complete non-access stratum (NAS) message is used to protect integrity and confidentiality of UL small packet transmission without attach/service request procedure during idle state. For downlink (DL) transmission of small packet from MTC device in idle state, a TAU accept NAS message is used to protect integrity & confidentiality of DL small packet reception without attach/service request procedure during idle state.

11. A method of transmitting data in a wireless communication system, the method performed by a machine type communication (MTC) device and comprising:
-
performing a random access procedure to a base station (BS); 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 signalling, wherein the first TAU accept message includes an MTC device triggering indication which is transmitted from an MTC server; retaining, in response to the first TAU request message, an RRC context which is obtained during the random access procedure; while retaining the RRC context, receiving a grant message to transmit uplink to data associated with the MTC device triggering indication; and transmitting, in response to the grant message, a Non-Access Stratum (NAS) message including the uplink data associated with the MTC device triggering indication. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
