Emulating virtual port control of airtime fairness using per station enhanced distributed channel access (EDCA) parameters

摘要

A technique for emulating virtual port control of airtime fairness for wireless stations using per station Enhanced Distributed Channel Access (EDCA) parameters. Specific parameters are received for each of a plurality of stations connected to the access point. An EDCA field of a beacon that stores a general EDCA parameter is set to an empty state. The beacon is broadcast to a plurality stations on the wireless communication network and within range of an access point. The beacon comprises a BSSID (Basic Service Set Identifier) for use by the plurality of stations to connect with the access point for access to the wireless communication network. The beacon also comprises an empty EDCA field. In response to broadcasting the empty EDCA parameter, receiving a direct inquiry from each of the plurality of stations for the general EDCA parameter. Each of the plurality of stations is responded to with a direct communication of a specific parameter corresponding to each station. A transmission is received from at least one of the stations complying with the specific parameter.

1. A computer-implemented method in access points for controlling uplink medium access of wireless stations connected to a wireless communication network, comprising:
receiving a specific parameter for each of a plurality of stations connected to the access point; setting an EDCA (Enhanced Distributed Channel Access) field of a beacon that stores a general EDCA parameter to an empty state; broadcasting the beacon to a plurality stations on the wireless communication network and within range of an access point, the beacon comprising a BSSID (Basic Service Set Identifier) for use by the plurality of stations to connect with the access point for access to the wireless communication network, wherein the beacon also comprises the empty EDCA field; in response to broadcasting the empty EDCA parameter, receiving a direct inquiry from each of the plurality of stations for the general EDCA parameter; responding to each of the plurality of stations with a direct communication of a specific parameter corresponding to each station; and receiving a transmission from at least one of the plurality of stations that complies with the respective specific parameter.
