Handoff decision system and method for considering performance anomaly in Wireless environment

摘要

The present invention determines a handoff of a mobile terminal in consideration of a performance anomaly phenomenon when a mobile terminal moves in a wireless LAN environment using a multiple transmission rate in a handoff decision in an IEEE 802.11 enterprise WLAN environment The present invention relates to a system and a method for determining a handoff in consideration of a performance anomaly in a wireless LAN environment, and collects statistics of transmission rate values according to RSSI values from an initially connected AP, A statistical data selection unit for selecting the transmission rate data according to the RSSI of the mobile terminal existing in the database at the point of time when the handoff should be determined; an AP status information determination unit for determining the currently connected AP status; According to the result of the AP state determination, And a handoff control unit for exchanging information exchange and handoff control messages for moving the mobile terminal to another AP according to a result of the handoff decision unit and performing handoff control.
