Abstract

A method of providing Quality of Service (QoS) in a wireless LAN system, wherein plural stations comprise the wireless LAN network, and wherein the wireless LAN network includes a protocol providing for contention periods and contention free periods, includes grouping the stations into a polling list set; selecting a number of the grouped stations for inclusion in a polling list subset, wherein preference is given to high-priority QoS stations in the polling list subset; and polling the high priority stations during a contention free period.

Claims

1. A method of providing Quality of Service (QoS) in a wireless LAN system, wherein plural stations comprise the wireless LAN network, wherein some of the stations are identified as high-priority stations requiring QoS, and wherein the wireless LAN network includes a protocol providing for contention periods and contention free periods, comprising:

grouping the stations into a polling list set;

selecting a number of the grouped stations for inclusion in a polling list subset, wherein preference for selecting stations from the polling list is given to stations which are identified as high-priority QoS stations; and

polling the high priority stations during a contention free period.

2. The method of claim 1 wherein said selecting includes including stations in the polling list subset as a function of the data transmitted by such stations.

3. The method of claim 1 wherein said polling includes setting the time period between successive contention free periods to be greater than the contention free period.

4. The method of claim 1 wherein said selecting includes varying the stations selected for inclusion in the polling list subset.

5. A method of providing Quality of Service (QoS) in a wireless LAN system, wherein plural stations comprise the wireless LAN network, wherein some of the stations are identified as high-priority stations requiring QoS, and wherein the wireless LAN network includes a protocol providing for contention periods and contention free periods;

and wherein the wireless LAN is connected with a wired LAN, comprising;

grouping the stations into a polling list set;

selecting a number of the grouped stations for inclusion in a polling list subset, wherein preference for selecting stations from the polling list is given to stations which are identified as high-priority QoS stations; and

polling the high priority stations during a contention free period.

6. The method of claim 5 wherein said selecting includes including stations in the polling list subset as a function of the data transmitted by such stations as determined by functionalities in the wired LAN.

7. The method of claim 5 wherein said polling includes setting the time period between successive contention free periods to be greater than the contention free period.

8. The method of claim 5 wherein said selecting includes varying the stations selected for inclusion in the polling list subset.

9. A method of providing Quality of Service (QoS) in a wireless LAN system, wherein plural stations comprise the wireless LAN network, wherein some of the stations are identified as high-priority stations requiring QoS, and wherein the wireless LAN network includes a protocol providing for contention periods and contention free periods, comprising:

grouping the stations into a polling list set;

selecting a number of the grouped stations for inclusion in a polling list subset, wherein preference for selecting stations from the polling list is given to stations which are identified as high-priority QoS stations;

setting the time period between successive contention free periods to be greater than the contention free period; and

polling the high priority stations during a contention free period.

10. The method of claim 9 wherein said selecting includes including stations in the polling list subset as a function of the data transmitted by such stations.

11. The method of claim 9 wherein said selecting includes varying the stations selected for inclusion in the polling list subset.

12. The method of claim 9 which includes providing a connection between the wireless LAN and a wired LAN, and wherein said selecting includes including stations in the polling list subset as a function of the data transmitted by such stations as determined by functionalitites in the wired LAN.
