Method and System for Removing Fault Applied for Machine to Machine Gateway

Provided are a method and a system for removing a fault applied for an M2M gateway. The method includes: receiving, by an M2M gateway, an automatic code matching command, wherein the automatic code matching command is sent when a communication fault is detected by a sensor; and performing, by the M2M gateway, code matching identification according to the received automatic code matching command, and adding the sensor in a sensor management component of the M2M gateway if code matching is performed successfully. According to the method and the system for removing a fault applied for an M2M gateway according to the disclosure, automatic fault removing between an M2M gateway and a sensor can be realized, and using of the M2M gateway can be recovered. The method for automatically removing a fault applied for an M2M gateway provides three fault removing mechanisms, different functions can be realized on different network elements, an M2M gateway and a sensor with an automatic fault removing function are realized, and the using reliability of the M2M gateway is effectively enhanced.
