<p>The present invention relates to a method for recovering an abnormal M2M node in an M2M system, and, more specifically, the method comprises the steps of: a communications management and delivery handling common service function (CMDH CSF) part of an intermediate node transmitting a request to a CMDH CSF part of a first application service node with which communications are to be made; in the case that a response transmission with respect to the request from a CMDH CSF part of the application service node is delayed reference time or more or the number of request transmissions without the response exceeds the number of reference tests, a discovery common service function (DIS CSF) part of the intermediate node transmitting the request to the second application service node to check the response transmission; in the case that a response is transmitted from the second application service node, the intermediate node requesting an application and service layer management part of the first application service node to let a device management function capability to perform diagnosis; the device management function capability of the first application service node making an inquiry for and using an operational status and statics to perform a self verification test; performing a rebooting operation when a problem is solved via the rebooting operation according to the self verification test result.</p> |
