Ad-hoc simple configuration
First Claim
1. A method of forming an ad-hoc wireless local area network, the method comprising:
- receiving a first user input on a device initiated by a user;
in response to receiving the first user input, entering a configuration mode on the device for configuring the device as one of an enrollee and a registrar in the ad-hoc wireless local area network;
receiving a second user input on the device initiated by the user for configuring the device as one of the enrollee and the registrar in the ad-hoc wireless local area network;
configuring the device as one of the enrollee and the registrar in response to the device receiving the second user input; and
enabling communications between the device and a second device in the ad-hoc wireless network,wherein configuring the device as one of the enrollee and the registrar comprises;
configuring the device as one of the enrollee and the registrar if the second user input is received by the device within a first predefined time of the first user input; and
configuring the device as the other of the enrollee and the registrar if the second user input is not received by the device within the first predefined time of the first user input.

Abstract
A protocol governing the operation of an ad-hoc WLAN enables each device in the WLAN to be configured as a registrar and/or an enrollee. Accordingly, each device is configurable to support both the registrar as well as enrollee modes of operations. In response to a time-driven user action, the device may be configured to enter into a registrar mode or an enrollee mode. While in the registrar mode, the device enters into an aggressive beaconing phase by setting its beacon contention window to a relatively very small value. The aggressive beaconing increases the probability of the discovery of the registrar by the enrollees. Optionally the device may prompt the user to select between a registrar and an enrollee mode of operation by displaying the option on an LCD panel.

23. A method of selecting a configuration of a device attempting to participate in an ad-hoc wireless local area network session, the method comprising:
-
receiving a first user input on the device; in response to receiving the first user input on the device, presenting an option to a user to configure the device as one of a registrar and an enrollee in the ad-hoc wireless local area network session; receiving a second user input on the device for configuring the device as one of the registrar and the enrollee in the ad-hoc wireless local area network; and configuring the device as one of the registrar and the enrollee in response to the device receiving the second user input; wherein configuring the device as one of the enrollee and the registrar comprises; configuring the device as one of the enrollee and the registrar if the second user input is received by the device within a first predefined time of the first user input; and configuring the device as the other of the enrollee and the registrar if the second user input is not received by the device within the first predefined time of the first user input. - View Dependent Claims (24)

25. A device configured to participate in an ad-hoc wireless local area network, the device comprising:
-
an interface configured to receive a first user input initiated by a user on the device and a second user input initiated by the user on the device, the second user input for configuring the device as one of an enrollee and a registrar in the wireless ad-hoc network; and a controller configured to; enter a configuration mode on the device for configuring the device as one of an enrollee and a registrar in response to the first user input, detect the second user input; and configure the device as one of the enrollee and the registrar in response to detecting the second user input; and
a timer;wherein the controller is operative to configure the device as one of the enrollee and the registrar if the controller detects the second user input before a time set on the timer reaches a known time, the controller further operative to configure the device as the other of the enrollee and the registrar if the controller does not detect the second user input before the time set on the first timer time reaches the known time. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)

44. A method of forming a wireless ad-hoc network between a first device and a second device, the method comprising:
-
turning on the first device; turning on the second device; starting a first timer on the first device; starting a second timer on the second device; pressing a button on the first device before the first timer'"'"'s elapsed time reaches a predefined time in order to configure the first device as an enrollee; avoiding a button press on the second device before the second timer'"'"'s elapsed time reaches the predefined time in order to configure the second device as a registrar; reducing a beacon contention window of the second device; transmitting beacons from the second device in accordance with the reduced beacon contention window; intercepting the transmitted beacons via the first device thereby enabling the first device to discover the second device; performing a handshake operation between the first and second devices; and forming the ad-hoc network.
