METHOD FOR SIMULTANEOUSLY TRANSMITTING DATA IN HETEROGENEOUS NETWORK

摘要

PURPOSE: A data simultaneous transmission service method based on a heterogeneous network is provided to promote the performance of a simultaneous transmission service by instantly detecting the loss of part data of each network from a reception apparatus side by inserting network transmission order information into a transmission side management apparatus. CONSTITUTION: A data division unit(410) divides transmission target data into two or more part data. A part data selection unit(420) selects two or more part data according to each connection network. An order information insertion unit(430) inserts division order information into two or more part data. The order information insertion unit inserts network transmission order information corresponding to the transmitted connection network into the selected part data. A communication unit(450) transmits the selected part data through two or more connection networks.
