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.
Claims26
An electronic device for transmitting and receiving data in a mobile communication system, the electronic device comprising:
- a communication unit configured to transmit and to receive a signal to and from another communication entity;
- and
- a control unit configured to:
- determine whether to activate a wireless local area network (WLAN), and
- 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,
- wherein the control unit is further configured, when the WLAN which is in a deactivated state is activated, to transmit a message for indicating activation of the WLAN to the packet data network through the WLAN.
A gateway device for transmitting and receiving data in a mobile communication system, the gateway device comprising:
- a communication unit configured to transmit and to receive a signal to and from another communication entity;
- and
- a control unit configured to select a communication network to transmit and receive data, depending on information about activation or deactivation of a wireless local area network (WLAN) by an electronic device, the information being received from the electronic device,
- wherein the control unit is further configured to, using a timer synchronized with the electronic device, determine that the electronic device deactivates the WLAN when there is neither transmission nor reception of data through the WLAN during a predetermined time.
A method for transmitting and receiving a signal at an electronic device in a mobile communication system, the method comprising:
- determining whether to activate a wireless local area network (WLAN);
- and
- transmitting 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,
- wherein the transmitting of the information includes, when the WLAN which is in a deactivated state is activated, transmitting a message for indicating activation of the WLAN to the packet data network through the WLAN.
A method for transmitting and receiving a signal at a gateway device in a mobile communication system, the method comprising:
- receiving information about activation or deactivation of a wireless local area network (WLAN) by an electronic device from the electronic device;
- using a timer synchronized with the electronic device, determining that the electronic device deactivates the WLAN when there is neither transmission nor reception of data through the WLAN during a predetermined time;
- and
- selecting a communication network to transmit and receive data, depending on the received information.
