Abstract
A method of operating a user station (STA) to scan for access points (APs). The STA broadcasts a probe request on a first saved channel of one or more saved channels. More specifically, each of the one or more saved channels corresponds to a channel on which the STA had prior communications with an AP. The STA remains on the first saved channel for an extended duration to listen for a probe response from a first AP. Specifically, the extended duration is greater than a dwell time of the STA when scanning wireless channels other than the one or more saved channels.
Claims20
A method for a station (STA) to scan for access points (APs), the method comprising:
- broadcasting a probe request on a first saved channel of one or more saved channels, wherein the STA received prior communications on each of the one or more saved channels;
- and
- remaining on the first saved channel for an extended duration to listen for a probe response from a first AP, wherein the extended duration is greater than a dwell time of the STA when scanning wireless channels other than the one or more saved channels.
A method of operating an access point (AP), the method comprising:
- receiving a probe request from a station (STA), wherein the probe request includes information identifying a first channel number and a first service set identifier (SSID);
- comparing the first channel number and the first SSID with a respective channel number and SSID associated with the AP;
- and
- selectively transmitting a probe response to the STA based on the comparison.
A wireless device, comprising:
- a memory element to store instructions for scanning for access points (APs);
- and
- one or more processors that, upon executing the instructions, cause the wireless device to:
- broadcast a probe request on a first saved channel of the one or more saved channels, wherein the wireless device received prior communications on each of the one or more saved channels;
- and
- remain on the first saved channel for an extended duration to listen for a probe response from a first AP, wherein the extended duration is greater than a dwell time of the wireless device when scanning wireless channels other than the one or more saved channels.
