Wireless local area network system, fault recovery method, and recording medium stored therein a computer program executing the fault recovery process

Abstract

The present invention provides a wireless local area network (LAN) system preventing throughput from being decreased even when a fault occurs in an access point, a fault recovery method, and a recording medium stored therein a computer program for executing the fault recovering process. The method for use in a wireless local area network system comprising a plurality of access points and a plurality of client terminals, the method comprising the steps of: detecting, by each of the access points, whether a fault occurs on each of the access points itself; disconnecting, by the access point which has detected the fault, the client terminal connected thereto; searching for, by the disconnected client terminal, another of the client terminals to which the disconnected client terminal is to be connected; and connecting the disconnected client terminal to the searched client terminal.

1 . A wireless local area network system comprising a plurality of access points and a plurality of client terminals; 
 wherein each of said plurality of access points comprises:    a main unit for communicating with said client terminals,    a first fault detecting unit for detecting a fault on said main unit, and    a disconnection controlling unit for disconnecting said client terminal connected to said access point where said fault was detected by said first fault detecting unit; and    wherein each of said plurality of client terminals comprises:    a transceiver unit for communicating with said access point,    a search controlling unit for searching for another client terminal to which said client terminal disconnected from said access point is to be connected, and    a connection controlling unit for connecting said disconnected client terminal to said searched client terminal by said search controlling unit independent of the plurality of access points.    
   
   
       2 . The wireless local area network system as defined in  claim 1 , wherein each of said client terminals further comprises a repeat controlling unit for controlling communication between said disconnected client terminal and one of said access points connected to said searched client terminal.  
   
   
       3 . A fault recovery method for use in a wireless local area network system comprising a plurality of access points and a plurality of client terminals, the method comprising the steps of: 
 detecting, by each of said access points, whether a fault occurs on each of said access points itself;    disconnecting, by said access point which has detected said fault, said client terminal connected thereto;    searching for, by said disconnected client terminal, another of said client terminals to which said disconnected client terminal is to be connected; and    connecting said disconnected client terminal to said searched client terminal independent of the plurality of access points.    
   
   
       4 . The fault recovery method for use in a wireless local area network system as defined in  claim 3 , further comprising the step of controlling, by said searched client terminal, communication between said disconnected client terminal and another of said access points connected to said searched client terminal.  
   
   
       5 . A recording medium storing therein a computer program for executing a fault recovery process for use in a wireless local area network system comprising a plurality of access points and a plurality of client terminals, the process comprising the steps of: 
 detecting, by each of said access points, whether a fault occurs on each of said access points itself;    disconnecting, by said access point which has detected said fault, said client terminal connected thereto;    searching for, by said disconnected client terminal, another of said client terminals to which said disconnected client terminal is to be connected; and    connecting said disconnected client terminal to said searched client terminal independent of the plurality of access points.    
   
   
       6 . The recording medium storing therein a computer program for executing the fault recovery process for use in a wireless local area network system as defined in  claim 5 , further comprising the step of controlling, by said searched client terminal, communication between said disconnected client terminal and another of said access points connected to said searched client terminal.
