This disclosure relates to multi-path data transmission techniques, and more particularly, to a method and apparatus for setting up a transmission environment for multi-path transmission.

In the electronic device, various services can be provided from another electronic device or server through a communication function. When transmitting and receiving data with other electronic devices or servers, an electronic device can transmit and receive data by generating a plurality of transmission connections through a multipath transport function.

The network controller 15 can check the status information of the plurality of networks 13 and adaptively reflect the status information of the plurality of networks 13 to control the performance of the multiplex transmission. For example, when there is a change in the status information of the plurality of networks 13, the network controller 15 re-sets the multi-path transmission environment information by reflecting the changed status information, and transmits the re- To the device 11 (S210). Accordingly, the first electronic device 11 re-creates a subflow for performing the multiplex transmission reflecting the reset multi-path transmission environment information (S211), and then transmits the subflow to the second electronic device 11 through the gateway device 14 To the electronic device 12 (S212, S213).
