APPARATUS FOR SIMULTANEOUSLY TRANSMITTING DATA IN HETEROGENEOUS NETWORK

摘要

Disclosed are a reception device and method for multiple network-based simultaneous data transmission and a transmission device and method for multiple network-based simultaneous data transmission in an environment which provides a simultaneous transmission service for transmitting and receiving partial data produced by partitioning data using a plurality of multiple networks, wherein transmission delay between networks is effectively measured using a transmission time interval and a reception time interval for partial data, thereby minimizing an unnecessary request for retransmission of partial data and improving the transmission performance and quality of the simultaneous transmission service based on the measured transmission delay between the networks.
