A system for providing an IoT service using an LTE terminal includes an LTE terminal including a sensor and a server for providing a data service of the LTE terminal, the server communicating in an FDD or TDD manner, And an IoT platform engine for determining a transmission scenario for transmission of the sensing information measured by the sensor of the LTE terminal and determining a data structure of the sensing information, Wherein the LTE terminal registers information on a transmission scenario and a data structure transmitted from the server and performs transmission of the sensing information according to a registered transmission scenario and a data structure .

The IoT platform engine of the server includes a transmission scenario control processor for determining the transmission scenario and delivering the transmission scenario to the terminal, and a data structure control processor for determining a data structure for the sensing information and delivering the data structure to the terminal .
