Abstract

A device and a method for providing a wireless LAN service in an electronic device are provided. The electronic device includes a communication interface that transmits and receives a signal for a wireless LAN service; and a processor that selects a plurality of channels using the communication interface and based on channel scan information, accesses at least one Access Point (AP) corresponding to at least one channel among the plurality of channels, and monitors the plurality of channels in a state in which the access to at least one AP is maintained.

First claim

What is claimed is:

1. An electronic device comprising:
a communication interface; and
a processor configured to:
perform a channel scan via the communication interface,
select a plurality of channels usable by the electronic device based on at least one of load information and supportable transmission rates of each channel included in channel scan information,
access at least one Access Point (AP) through at least one first channel among the plurality of channels,
monitor, while access to the at least one AP is maintained, state information of the plurality of channels including the at least one first channel used to access the at least one AP,
select at least one second channel using a medium access state of each of the plurality of channels and the monitored state information of the plurality of channels including the at least one first channel used to access the at least one AP, and transmit data using the selected at least one second channel among the plurality of channels, via the communication interface,
wherein the medium access state includes at least one of a contention window (CW) and a network allocation vector (NAV).

2. The electronic device of claim 1 , wherein the communication interface includes a plurality of connection managers, which manage the medium access state of each of the plurality of channels.

3. The electronic device of claim 1 , wherein the processor is configured to control access to at least one AP using a plurality of Medium Access Control (MAC) addresses allocated to the communication interface, an expansion address of a MAC address allocated to the communication interface, or a plurality of Internet Protocol (IP) addresses allocated to the communication interface.

4. The electronic device of claim 1 , wherein the processor is further configured to control access to different APs during different time periods using a Medium Access Control (MAC) address allocated to the communication interface.

5. The electronic device of claim 1 , wherein the processor is further configured to select the at least one second channel based on at least one of a priority, a signal strength, and a medium obtaining time of each channel.

6. A method for operating an electronic device, the method comprising:
performing a channel scan;
selecting a plurality of channels usable by the electronic device based on at least one of load information and supportable transmission rates of each channel included in channel scan information;
accessing at least one Access Point (AP) through at least one first channel among the plurality of channels;
monitoring, while access to the at least one AP is maintained, state information of the plurality of channels including the at least one first channel used to access the at least one AP;
selecting at least one second channel using a medium access state of each of the plurality of channels and the monitored state information of the plurality of channels including the at least one first channel used to access the at least one AP; and
transmitting data through the selected at least one second channel among the plurality of channels,
wherein the medium access state includes at least one of a contention window (CW) and a network allocation vector (NAV).

7. The method of claim 6 , wherein accessing at least one AP comprises accessing at least one AP using at least one of a plurality of Medium Access Control (MAC) addresses allocated to a communication interface of the electronic device, an expansion address of a MAC address allocated to the communication interface, and a plurality of Internet Protocol (IP) addresses allocated to the communication interface.

8. The method of claim 6 , wherein accessing at least one AP comprises accessing different APs, during different time periods, using a Medium Access Control (MAC) address allocated to a communication interface of the electronic device.
