Abstract
A method and apparatus for a wireless device that can adapt a rate of related wireless network unit scans for adjacent networks is disclosed. In one embodiment, the wireless device can include a wireless network unit and a co-located geo-location signal receiver, and a processor. The processor can determine the position and speed of the wireless device from data received from the geo-location signal receiver. The processor can configure the wireless network unit to adapt the rate of related wireless network scans based upon determined speed and position. In one embodiment, the wireless network unit scans can be wireless scans for other nearby networks for roaming or location based services.
Claims17
A method, comprising:
- determining a position of a wireless device based at least in part on location signals;
- determining whether the position of the wireless device has changed;
- in response to determining that the position of the wireless device has changed, comparing the change of the position of the wireless device with a first predetermined distance;
- and
- in response to the change of the position of the wireless device being greater than the first predetermined distance, decreasing a period of time between successive roam scans,
- wherein the first predetermined distance is based at least in part on a coverage rang of an access point.
A wireless device, comprising:
- a geo-location signal receiver configured to:
- determine a position of the wireless device based at least in part on location signals;
- and
- a processor configured to:
- determine whether the position of the wireless device has changed;
- in response to determining that the position of the wireless device has changed, compare the change of the position of the wireless device with a first predetermined distance;
- in response to the change of the position of the wireless device being greater than the first predetermined distance, decrease a period of time between successive network scans;
- in response to the change of the position of the wireless device being less than the first predetermined distance, compare the change of the position of the wireless device with a second predetermined distance, wherein the second predetermined distance is different from the first predetermined distance;
- and
- in response to the change of the position of the wireless device being less than the second predetermined distance, increase the period of time between successive network scans.
A non-transitory computer-readable storage medium storing instructions which, when executed by a wireless device, cause the wireless device to perform a method comprising:
- determining a position of a wireless device based at least in part on location signals;
- determining whether the position of the wireless device has changed;
- in response to determining that the position of the wireless device has changed, comparing the change of the position of the wireless device with a first predetermined distance, wherein the first predetermined distance is based at least in part on a coverage range of an access point;
- in response to the change of the position of the wireless device being greater than the first predetermined distance, decreasing a period of time between successive roam scans;
- in response to the change of the position of the wireless device being less than the first predetermined distance, comparing the change of the position of the wireless device with a second predetermined distance, wherein the second predetermined distance is different from the first predetermined distance;
- and
- in response to the change of the position of the wireless device being less than the second predetermined distance, increasing at least one of the period of time between successive roam scans or a period of time between successive location scans.
