Claim One:
1. A network self-construction method in a wireless communication system including L access points (APs), each of which manages its own network operation, and a plurality of network devices, each of which makes operation through network association to one of the L APs, in which each AP transmits a beacon signal including an association control message to network devices, and a system manager managing the L APs performs network construction, while separating the wireless communication system into L networks, the method comprising: (A) transmitting, by the system manager, an association control message including a network construction permission command, a network identifier (NI) information and the number of association-permitted network devices, to a specific AP among the L APs, and powering on only network devices to be associated to the specific AP, so as to associate the network devices to the specific AP's network; and (B) transmitting, by the system manager, an association control message including a network construction non-permission command to the specific AP when a network construction of the specific AP is completed, and repeating step (A) to another AP, whose network construction has not yet been completed, so that the L networks are separately constructed in a sequential manner.
