Method, apparatus, and system for realization of internet-of-things converged gateway

The invention, which relates to the technical field of the internet of things, discloses a method, apparatus, and system for realization of an internet-of-things converged gateway. With the method, the apparatus, and the system, problems that easy popularization can not be realized caused by proprietary protocol utilization between a CN and an IGW and the sensing capability for the CN is poor in the prior art can be solved. The method comprises the following steps that: an internet-of-things converged gateway sends a data request packet in a universal interface format to a terminal node and monitors a heartbeat request packet that is sent by the terminal node and is in a universal interface format; and if the internet-of-things converged gateway does not receive a date response packet that is returned by the terminal node and is in a universal interface format, the working situation of the terminal node is determined according to the situation of the monitored heartbeat request packet. According to the invention, the method, the apparatus, and the system are mainly applied to the internet of things.
