Adaptive polling of wireless devices
First Claim
Patent Images
1. A method, comprising:
- monitoring a wireless channel to determine a fraction of time the channel is busy;
comparing the fraction with a value; and
transmitting an unsolicited poll to a mobile wireless device resultant to the fraction being greater than the value, but not transmitting the unsolicited poll to the mobile wireless device resultant to the fraction being less than the value.

Abstract
In a wireless network, the decision of when and whether to send unsolicited polls to a particular mobile wireless device may be made by monitoring communications conditions affecting the ability of the particular device to gain channel access, and sending unsolicited polls if the ability to gain channel access is below a threshold value. Such conditions may include one or more of channel load, device transmission load, collision rate, and number of mobile wireless devices contending for access.

6. An apparatus comprising
a wireless device to: -
monitor at least one indicator of channel availability for a particular mobile wireless device; determine at least one parameter based on said monitoring; compare said at least one parameter with at least one threshold value; and transmit an unsolicited poll to the particular mobile wireless device resultant to the comparison indicating that channel availability is less than a predetermined level of channel availability, but not transmit the unsolicited poll to the particular mobile wireless device resultant to the comparison indicting that the channel availability is not less than the predetermined level of channel availability. - View Dependent Claims (7, 8, 9, 10, 11)

12. A system comprising
a wireless device comprising an omni-directional antenna, the wireless device to: -
monitor at least one indicator of channel availability for a particular mobile wireless device; determine at least one parameter based on said monitoring; compare said at least one parameter with at least one threshold value; and transmit an unsolicited poll to the particular mobile wireless device resultant to the comparison indicating that channel availability is less than a predetermined level of channel availability, but not transmit the unsolicited poll to the particular mobile wireless device resultant to the comparison indicting that the channel availability is not less than the predetermined level of channel availability. - View Dependent Claims (13, 14, 15, 16, 17)
