System and method for protecting the loss of data between low-power network and non-low-power network

A matching system for preventing a loss of data between a low-power network and a non-low-power network and a method therefor are provided to transmit data according to the RF communication period of the low-power network of a low-rate network in the non-low-power network of a high-rate network, thereby preventing the data from being lost. A heterogeneous network communication unit(13,22) receives an RF(Radio Frequency) communication period from a low-power network and transceives data with the low-power network. A heterogeneous network communication scheduling unit(14) schedules the heterogeneous network communication unit to transmit the data during the RF communication pause time of the low-power network by using the RF communication period received from the heterogeneous network communication unit.
