Prioritising access by an access point and implementation of a simple 802.11e hcf (hybrid coordination function)

The invention claims a hybrid coordinating function (HCF) is realized, the distributive cooperation transmission function and connection point prior (E) DCF the supplemented is composed at least strict prioritizing transmission HCF forming. The HCF forming is used for scheduling downlink data, and CF polling transmitting is provided with a downlink current and uplink current of grant. 802.1D and user value is used to for grant the HCF formation of stream. The priority by, the strict prioritizing transmission HCF the first is downward served to any other (E) DCF transmission annular. The strict and formation of the served; the channel is considered busily to the (E) DCF transmission and. The grant controller is for controlling the data stream, and preventing strict and current capacitor is a (E) DCF current capacity hungry. The single simple AND dispatching is used for setting of the polling time and a wakeup the time. Different embodiment of this invention includes distributed measuring fixed to the transmission opportunities, a province power-station part is awaken scheduling, realizing polling scheduling of the seat, a dispatching based on timer wheel; and a preset value token token column is a data stream distribution.
