|Applicants:||SK TELECOM CO., LTD.
|Title:||DEVICE AND METHOD FOR SUPPORTING MULTI-NETWORK BASED SIMULTANEOUS DATA TRANSMISSION SERVICE|
Disclosed is a transmission and reception device and a transmission and reception method for multi-network based simultaneous data transmission in an environment which provides a simultaneous transmission service for transmitting/receiving partial data produced by partitioning data using a plurality of multiple data networks, wherein non-received partial data are immediately determined as lost data if partial data having transmission sequence information are received after the non-received partial data according to each of the multiple networks on the basis of each piece of transmission sequence information of the received partial data, and the partial data are transferred to an upper layer without waiting for the transmission of the partial data having the transmission information, thereby reducing an unnecessary reordering waiting time in a receiving-side device and improving the transmission performance of the simultaneous transmission service.
