ESS CONTROL AND MANAGEMENT SYSTEM FOR PROVIDING GUARANTEED QOS IN THE WIRELESS LAN ENVIRONMENT FAST BSS TRANSITION

摘要

The present invention relates to an ESS control and management system for providing a QoS guaranteed high-speed BSS transition in a wireless LAN environment, which identifies traffic conditions of each BSS in the ESS overall perspective in a wireless LAN environment, can continuously guarantee QoS to a wireless terminal that requires a transition, and enables a QoS guaranteed high-speed BSS transition as a network selects an AP which is the most appropriate for traffic load distribution or the like. In the ESS control and management system for providing a QoS guaranteed high-speed BSS transition in a wireless LAN environment including an ESS-CM part and a BSS/AP part, the ESS-CM part periodically gathers traffic information from a BSS agent installed in each BSS/AP part, and manages upstream and downstream traffic information for each BSS and each access category (AC) in a database, so as to select an AP which can continuously guarantee QoS and enable a high-speed transition.
