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 configured to transmit and receive a signal for a wireless LAN service; and a processor configured to:
select a plurality of channels using the communication interface and based on channel scan information,
access at least one Access Point (AP) corresponding to at least one channel among the plurality of channels, and
monitor the plurality of channels in a state in which the access to at least one AP is maintained.

2 . The electronic device of claim 1 , wherein the communication interface includes at least one connection manager which manages medium access states of each of the plurality of channels according to each channel.

3 . The electronic device of claim 1 , wherein the processor is configured to select a plurality of channels which are usable in the electronic device based on at least one of load information and supportable transmission rates of each channel.

4 . The electronic device of claim 1 , wherein the processor is configured to control access to at least one AP using a plurality of MAC addresses allocated to the communication interface, an expansion address of a MAC address allocated to the communication interface, or a plurality of IP addresses allocated to the communication interface.

5 . The electronic device of claim 1 , wherein the processor is configured to control access to different APs during different time periods using a MAC address allocated to the communication interface.

6 . The electronic device of claim 1 , wherein the processor is configured to select at least one channel based on monitoring information of the plurality of channels and transmit data through at least one selected channel.

7 . The electronic device of claim 6 , wherein the processor is configured to additionally select at least one channel using at least one of a priority, a signal strength, a medium access state and a medium obtaining time of each channel based on load information of each channel, and
wherein the medium access state includes at least one of a contention window (CW) and a Network Allocation Vector (NAV).

8 . The electronic device of claim 6 , wherein the processor is configured to select at least one channel based on expected data transmission rates of each channel.

9 . The electronic device of claim 1 , further comprising:
a plurality of antennas, wherein the processor is configured to maintain the access at least one AP using at least one antenna among the plurality of antennas, and monitor the plurality of channels using at least one of remaining antennas.

10 . An electronic device comprising:
a communication interface configured to transmit and receive a signal for a wireless LAN service; and a processor configured to:
control to identify a plurality of Access Points (APs) using the communication interface, and based on channel scan information,
select at least one AP among the APs based on monitoring information for a channel of the APs, and
transmit data through at least one selected AP.

11 . A method for operating an electronic device, the method comprising:
performing a channel scan; selecting a plurality of channels based on channel scan information; accessing at least one Access Point (AP) corresponding to at least one channel among the plurality of channels; and monitoring the plurality of channels in a state in which the access to at least one AP is maintained.

12 . The method of claim 11 , wherein selecting the plurality of channels comprises selecting a plurality of channels which are usable in the electronic device based on at least one of load information and supportable transmission rates of each channel.

13 . The method of claim 11 , wherein accessing at least one AP comprises accessing at least one AP using at least on of a plurality of 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 IP addresses allocated to the communication interface.

14 . The method of claim 11 , wherein accessing at least one AP comprises accessing different APs during different time periods using a MAC address allocated to a communication interface of the electronic device.

15 . The method of claim 11 , further comprising:
selecting at least one channel based on monitoring information of the plurality of channels; and transmitting data through at least one selected channel.

16 . The method of claim 15 , wherein selecting at least one channel comprises selecting at least one channel additionally using at least one of a priority, a signal strength, a medium access state and a medium obtaining time of each channel based on load information of each channel, and
wherein the medium access state includes at least one of a contention window (CW) and a Network Allocation Vector (NAV).

17 . The method of claim 15 , wherein selecting at least one channel comprises selecting at least one channel based on expected data transmission rates of each channel.

18 . The method of claim 11 , wherein monitoring the plurality of channels comprises maintaining the access at least one AP using at least one antenna among a plurality of antennas included in the electronic device, and monitoring the plurality of channels using at least one of remaining antennas.

19 . A method for operating an electronic device, the method comprising:
performing a channel scan; identifying a plurality of Access Points (APs) based on information on the channel scan; monitoring a channel of the APs; selecting at least one AP among the APs based on information on the monitoring of the channel; and transmitting data through at least one selected AP.

20 . The method of claim 19 , wherein selecting at least one AP comprises selecting at least one AP for transmitting data based on at least one of load information and signal strengths of the APs.
