M2M SYSTEM BASED ON MOBILE COMMUNICATION NETWORK, DATA TRANSMISSION METHOD OF M2M DEVICE OVER MOBILE COMMUNICATION NETWORK, AND DATA TRANSMISSION METHOD OF M2M DEVICE OVER LET NETWORK

摘要

A data transmission method of an M2M device over a mobile communication network comprises the steps of: collecting, by at least one of a plurality of M2M devices having the same device ID, data; authenticating, by a mobile communication network device, the plurality of M2M devices by using the same device ID that is transferred by at least one of the plurality of M2M devices and that is shared by the plurality of M2M devices, and then allowing, by the mobile communication network device, connection of the plurality of M2M devices; and transmitting, by at least one of the plurality of M2M devices, data to the mobile communication network device. The plurality of M2M devices transmit data in a predetermined time interval spanning from the time at which data transmission is possible, and each of the plurality of M2M devices transmits data at different time points in the time interval when transmitting data.;COPYRIGHT KIPO 2017
