APPARATUS AND A METHOD FOR MANAGING AN AP FAILURE OF A WIRELESS LAN SYSTEM, PARTICULARLY FOR ENABLING THE WIRELESS LAN SYSTEM TO SENSE A FAILURE BY USING A MESSAGE TRANSMITTED BY AN AP

摘要

Purpose: a kind of a kind of device and method for an AP (entrance) failure managing wireless local area network (WLAN) system be arranged to reduce maintenance cost reduce one largely failure sensing functions from a Network Management System and an AP analyze a message received, to reduce labour cost. Construction: in an AP, a timer checks a notice period, and when reaching (S211) in a scheduled notice period, a message generating unit generates a message, the message that communication unit transmission generates a to NMS (Network Management System) (S212). NMS monitors a, if message is in every notice period.It is received from AP, if there is an AP, does not have message to be received (S221) from it, NMS, which is determined, has failure and by using PING or SNMP ballots (S225) confirmation failure. A communication unit of NMS is from the communication unit received message of AP (S222), and message analysis device analysis received message is to determine whether the failure in AP (S223). A timer of NMS checks the notice period of every AP and determines whether an AP, is received (S224) without message. If there is the AP being received without message, the communication unit of NMS checks that the failure of AP (S225) is reaffirmed in the failure of AP. If AP has failure (S226), NMS notifies an operator for its solution about the failure of AP (S231).
