APPARATUS FOR SIMULTANEOUSLY TRANSMITTING DATA IN HETEROGENEOUS NETWORK

摘要

PURPOSE: An apparatus for supporting the heterogeneous network based data simultaneous transmission service is provided to reduce the realigning waiting time which is unnecessary in a receiver device, thereby enabling a quick request for the retransmission of the partial data which is not received. CONSTITUTION: A control unit (130) confirms the partial data having the transmission order information after the transmission order information of the partial data which is not received, in correspondence to the partial data received through more than two connection networks. If the partial data received from the front part of more than two connection networks is included in the confirmed partial data, the control unit determines the not received partial data as being lost. The control unit requests the retransmission of the not received partial data. [Reference numerals] (110) Communication unit; (120) Buffer unit; (130) Control unit
