Method for intelligent communicating management of electronic shelf lable system

PURPOSE: An intelligent communication management method of an ESL(Electronic Shelf Label) system is provided to transmit transmission packets including a state field indicating the state information of a communication terminal device to a second communication terminal device. CONSTITUTION: When a first communication terminal device wirelessly communicates with a second communication terminal device, the first communication terminal device transmits a transmission packet to the second communication terminal device. The transmission packet includes a state field indicating the state information of the first communication terminal device. The state field includes the booting state information of the first communication terminal device, operation state information, communication state information, wireless channel quality state information, or battery state information.
