Abstract
Methods and system for weighted polling of terminals in a Wireless Local Area Network (WLAN). Quality of Service (QoS) information related to WLAN terminals is obtained. A weighted polling factor may be assigned to each WLAN terminal based on the QoS information. Each WLAN terminal may be polled during a transmission period based on the weighted polling factor assigned to each WLAN terminal.
Claims19
A method for weighted polling of terminals in a Wireless Local Area Network (WLAN) comprising:
- obtaining Quality of Service (QoS) related information related to WLAN terminals;
- assigning a weighted polling factor to each WLAN terminal based on the QoS information, each weighted polling factor denoting a number of times each said WLAN terminal is to be polled;
- and
- polling each WLAN terminal during a transmission period based on the weighted polling factor assigned to each WLAN terminal, the weighted polling factor assigned for each said WLAN terminal being changeable between each said transmission period.
A method for transferring data based on weighted polling of terminals in a Wireless Local Area Network (WLAN) comprising:
- dividing data to be transferred into best effort data and real time data;
- storing the best effort data in a best effort queue;
- storing the real time data in a real time queue;
- obtaining information related to at least one WLAN terminal associated with some real time data;
- assigning a weighted polling factor to each at least one WLAN terminal based on the information;
- placing a terminal identification of each at least one WLAN terminal in a polling list at least once based on the weighted polling factor of each at least one WLAN terminal;
- polling WLAN terminals whose terminal identification is in the polling list based on a number of times each WLAN terminal identification is listed in the polling list, each polled WLAN terminal transferring the associated real time data during a transmission period.
A Wireless Local Area Network (WLAN) Quality of Service (QoS) system that provides weighted polling of WLAN terminals comprising:
- a WLAN;
- at least one access point operatively connected to the WLAN, the access point including:
- a real time data queue;
- a best effort data queue;
- a data packet classifier, the data packet classifier separating data into real time data and best effort data;
- a data transfer manager, the data transfer manager storing the real time data in the real time data queue and the best effort data in the best effort data queue;
- and
- a polling list;
- at least one WLAN terminal operatively connected to the at least one access point, the data transfer manager obtaining QoS related information related to the at least one WLAN terminal and assigning a weighted polling factor to each at least one WLAN terminal based on the QoS related information,
- wherein the data transfer manager places a terminal identification of each at least one WLAN terminal related to some real data in the polling list at least once based on the weighted polling factor of each at least one WLAN terminal, the data transfer manager polling WLAN terminals whose terminal identification is in the polling list based on a number of times each WLAN terminal identification is listed in the polling list, each polled WLAN terminal transferring its related real time data during a transmission period.
