<p>The present invention relates to a method and apparatus for ensuring the reliability of a request message and, more particularly, to an M2M system including: a base node receiving a first request message for a first device node, transmitting the request message to an intermediate node, and transmitting a second request message to the intermediate node when receiving the request for retransmission of the first request message; the intermediate node transmitting the first request message to the first device node, receiving a result of verifying the validity of the first request message from the first device node, and receiving the second request message to transmit the first device node when the verification result is invalid; and a first device receiving the first request message, transmitting the result of verifying the validity to the intermediate node, and executing the second request message by receiving the second request message.</p> |
