1. A method of transmitting a power outage report at a machine-to-machine (M2M) device in a wireless communication system, the method comprising:
- receiving, from a base station, a first message including a predefined bandwidth request (BR) index and a corresponding BR action which is used in case of a three step BR procedure of the M2M device in a connected state, wherein the first message is a dynamic service addition (DSA) request message, and the predefined BR index is used to indicate an abnormal power outage in the M2M device in the connected state;
transmitting, to the base station, a second message including the predefined BR index to indicate that the abnormal power outage has occurred in the M2M device; and
starting a timer, after transmitting the second message, to wait for a third message including an acknowledgement of the second message from the base station within a predetermined time.

Abstract
Disclosed are a method for transmitting and receiving a power outage report and a device therefor. According to the present invention, a method for allowing a machine to machine (M2M) device to transmit a power outage report comprises a step of transmitting, to a base station, a first message which contains a bandwidth request (BR) index value defined in advance if a power outage occurs, wherein said BR index value defined in advance is allocated to indicate to said M2M device that the power outage has occurred.
