METHOD FOR PROVIDING DISCRIMINATED SERVICES BASED ON PRIORITY IN WIRELESS LAN ENVIRONMENT

摘要

A method of providing priority-based discriminated services in a wireless LAN environment. More particularly, providing discriminated services while maintaining compatibility with existing 802.11 MAC through a priority index map configured to enable discriminated services. A method of providing priority-based discriminated services in a wireless LAN environment consistent with the present invention includes determining priority ranks for terminals in the wireless LAN environment; and determining backoff times based on the determined priority ranks, and attempting to occupy a channel by sending frames according to the determined backoff times if predetermined channel occupation latency elapses after the transmission of a last frame is completed.
