Abstract

A method and device for configuring a link in a wireless LAN system are disclosed. The wireless link configuration method comprises the steps of: acquiring a first probe request message transmitted by a first mobile terminal; delaying the transmission of a second probe request message when the first probe request message is similar to the second probe request message which is prepared for transmission by a second mobile terminal; receiving a probe response message, which is a response to the first probe request message, from a wireless access device; and withdrawing the transmission of the second probe request message when information included in the probe response message satisfies requirements of the second mobile terminal. Therefore, a time for configuring a link between wireless LAN devices can be reduced.

Claims

1. A method of configuring a wireless link, performed in a second mobile station, the method comprising:

obtaining a first probe request message transmitted from a first mobile station;

when the first probe request message is similar to a second probe request message which the second mobile station prepares to transmit, delaying transmission of the second probe request message;

receiving a probe response message from a wireless access station in response to the first probe request message; and

when information included in the probe response message satisfies requirements of the second mobile station, cancelling the transmission of the second probe request message.

2. The method of claim 1, wherein, in the delay transmission of the second probe request message, when service set identifiers (SSID) of the first probe request message and the second probe request message coincide with each other, the second probe request message is delayed for at least a maximum channel time (MaxChannelTime).

3. The method of claim 1, further comprising transmitting the second probe request message, when capability information included in the probe response message does not satisfy the requirements of the second mobile station.

4. The method of claim 1, further comprising requesting authentication to the wireless access station by using wireless access information obtained from the probe response message.

5. A second mobile station comprising:

a control part controlling operations of the second mobile station; and

at least one network interface card for transmitting and receiving data based on commands of the control part,

wherein the control part obtains a first probe request message transmitted from a first mobile station, delays transmission of the second probe request message when the first probe request message is similar to a second probe request message which the second mobile station prepares to transmit, receives a probe response message from a wireless access station in response to the first probe request message, and cancels the transmission of the second probe request message when information included in the probe response message satisfies requirements of the second mobile station.

6. The station of claim 5, wherein, when service set identifiers (SSID) of the first probe request message and the second probe request message coincide with each other, the control part delays the second probe request message for at least a maximum channel time (MaxChannelTime).

7. The station of claim 5, wherein the control part transmits the second probe request message, when a capability element included in the probe response message does not satisfy the requirements of the second mobile station.

8. The station of claim 5, wherein the control part requests authentication to the wireless access station by using wireless access information obtained from the probe response message.
