Abstract

A communication system comprising one or more wireless stations programmed to await for an authorizing signal to initiate wireless communications with a network controller or access point. The network controller maintains identification information in different queues, and polls stations from those queues. The wireless station identification information may be moved between the different queues in response to wireless station activity. Between polling, each mobile station aggregates data for the next opportunity to transmit. Multi-polling may be employed such that more than a single station is polled at a time. Polling is accomplished by polling one of the more stations from each queue having the effect that stations in one queue are polled more often than those in another queue. If a lesser active station becomes active, it may be moved into the shorter queue and consequently will be polled more often.

First claim

What is claimed:

1 . A method of network communications including:
maintaining at an access point a first queue and a second queue, each of said queues including identification information of a plurality of remote stations; polling one station from the first queue and one station from the second queue; receiving from a responding remote station a transmission duration for an aggregated data packet, said aggregated packet including a plurality of smaller data packets; transmitting to the responding remote station a transmission time value, said transmission time value responsive to the transmission duration; receiving the aggregated data packet, and moving the identification information of the responding remote station to a different queue in response to the transmission duration.

2 . The method of claim 1 wherein the first queue and the second queue are polled at a different rate.

3 . The method of claim 1 wherein the first queue includes identification information from stations having lower data volume than stations in the second queue.

4 . The method of claim 1 wherein the first queue includes identification information from stations of lower transmission time than stations in the second queue.

5 . The method of claim 1 wherein said polling includes simultaneously transmitting to at least two stations, each of said stations from a different queue, a query, said query requesting an indication of a transmission duration.

6 . The method of claim 5 wherein said simultaneously transmitting to at least two stations includes sending a single packet addressed to both a station from the first queue and a station from the second queue.

7 . A memory device, said device including processor readable, non-transitory instructions directing a processor to perform a method including:
maintaining at an access point a first queue and a second queue, each of said queues including identification information of a plurality of remote stations; polling one station from the first queue and one station from the second queue; receiving from a responding remote station a transmission duration for an aggregated data packet, said aggregated packet including a plurality of smaller data packets; transmitting to the responding remote station a transmission time value, said transmission time value responsive to the transmission duration; receiving the aggregated data packet, and moving the identification information of the responding remote station to a different queue in response to the transmission duration.

8 . The device of claim 7 wherein the first queue and the second queue are polled at a different rate.

9 . The device of claim 7 wherein the first queue includes identification information from stations having lower data volume than stations in the second queue.

10 . The device of claim 7 wherein the first queue includes identification information from stations of lower transmission time than stations in the second queue.

11 . The device of claim 7 wherein said polling includes simultaneously transmitting to at least two stations, each of said stations from a different queue, a query, said query requesting an indication of a transmission duration.

12 . The device of claim 11 wherein said simultaneously transmitting to at least two stations includes sending a single packet addressed to both a station from the first queue and a station from the second queue.
