ELECTRONIC DEVICE SUPPORTING DUAL CONNECTIVITY AND METHOD OF OPERATING THE SAME

An electronic device may include a first communication processor supporting first network communication with a first network, and a second communication processor supporting second network communication with a second network different from the first network. When both of the first network communication and the second network communication are set to a data transmittable state, the second communication processor may be configured to transmit transmission data based on the second network communication selected as a primary path from between the first network communication and the second network communication, when the size of the transmission data is less than a predetermined threshold. In response to detection of a failure in the second network communication, the first communication processor may be configured to transmit the transmission data based on the first network communication, irrespective of whether the size of the transmission data is equal to or larger than the predetermined threshold.
