Abstract: An electronic device, a gateway device, and signal transmission and reception methods thereof are provided. The electronic device includes a communication unit and a control unit. The communication unit is configured to transmit and to receive a signal to and from another communication entity. The control unit is configured to determine whether to activate a wireless local area network (WLAN), and to transmit information about activation or deactivation of the WLAN to a packet data network so as to maintain a created channel and authentication for data transmission and reception.
