RADIO LAN SYSTEM, ITS FAULT RELIEF METHOD AND RECORDING MEDIUM RECORDING COMPUTER PROGRAM FOR REALIZING FAULT RELIEF PROCESSING

摘要

PROBLEM TO BE SOLVED: To prevent the drop of a throughput when an access point breaks down by detaching a client terminal to which the access point detecting the occurrence of the fault is connected and connecting the detached client terminal to a client terminal which is newly retrieved. SOLUTION: When an access point Pa detects faults in the main device of the access point Pa itself and a LAN cable 5 connected to it, the connection of a client, terminal Ca and the access point Pa is cut. On the other hand, the other access point Pb transmits permission information Ip based on beacon information Iba from the access point Pa. When client terminals Cb to Cd existing in an area Ab receive permission information Ip, they are set to the reception permission state of an urgent identification code. The detached client terminal Ca transmits the urgent identification code to the client terminal Cd and executes a connection processing.
