Device and method for simultaneous data transmission service in heterogeneous network

Abstract

Disclosed is a method for simultaneous data transmission service in heterogeneous networks, comprising: a data splitting step in which a transmission device splits data into two or more partial data; a data transmission step in which the transmission device transmits, through two or more networks, the items of split partial data, each including access information for a virtual network; a data receiving step in which a receiving device receives each of items of the partial data through two or more networks; a first data generation step in which the receiving device generates data by combining the items of partial data on the basis of the virtual network access information accompanying each of the items of partial data received thereby; an abnormality occurrence confirmation step in which the transmission device confirms an occurrence of an abnormality in a particular network among the two or more networks; a data transmission switch step in which the transmission device transmits the partial data, which is transmitted through the particular network, and which includes the access information for the virtual network, is transmitted through another network among the two or more networks to which a switch has been made; a second data generation step in which the receiving device generates data by authenticating the virtual network access information for the partial data received after a switch has been made to another network. Thus, by enabling data transmission and reception through valid networks on the basis of the virtual network access information, even during disconnection from a particular network in a heterogeneous network, continuity of service is guaranteed, and consequently, an efficient and highly reliable simultaneous data transmission service in heterogeneous networks can be achieved.

Description

technical field [0001] The present disclosure relates to a simultaneous data transmission scheme, and more particularly, to a method for providing a simultaneous data transmission service based on a heterogeneous network, a sending device according to the method, an operation method of the sending device, and a method according to the method Receiving device and operating method of the receiving device, wherein, when data to be transmitted is divided and the divided data are simultaneously transmitted in a heterogeneous network environment, virtual network access for realizing simultaneous link transmission through a heterogeneous network The virtual network access information is managed after the information is additionally allocated to each terminal, so that data transmission / reception can be performed through an effective network based on the virtual network access information even when a specific network is disconnected. Background technique [0002] Recently, service pr...
