WIRELESS NETWORK MANAGEMENT PROCEDURE, A STATION SUPPORTING THE PROCEDURE, AND FRAME FORMAT FOR THE PROCEDURE, PARTICULARLY FOR REDUCING THE BURDEN OF A WLAN SYSTEM INCLUDING A REQUESTING STA AND A REQUESTED STA AND ENHANCING THE UTILIZATION EFFICIENCY OF WIRELESS CHANNEL TO ENABLE EFFICIENT WIRELESS NETWORK MANAGEMENT

摘要

PURPOSE: A wireless network management procedure, a station supporting the procedure, and frame format for the procedure are provided to reduce the burden of the WLAN system including a requesting STA and a requested STA and enhance the utilization efficiency of wireless channel to enable efficient wireless network management.;CONSTITUTION: A radio measurement procedure in a wireless communication system includes as preliminary procedures a scanning procedure, an authentication procedure(S20), and/or an association procedure(S30) and further includes a management procedure(S40) which is performed after the preliminary procedures to S30. The scanning procedure SlO is a procedure for allowing the first STA 2 to search for a candidate station to be associated in the association procedure S30, for example, a procedure for allowing a non-AP STA to search for an AP in the infrastructure BSS. However, the scanning procedure in a wider meaning may include a procedure for allowing a non-AP STA to search for a neighboring non- AP STA in the IBSS or a procedure for allowing an MP to search for its neighboring MP in a mesh network. The scanning procedure can be classified into two types. One is a passive scanning method using a beacon frame transmitted from APs including the second STA 4. In this method, the first STA 2 to access a wireless LAN can search for an accessible BSS by receiving a beacon frame periodically transmitted from the second STA 4 which is an AP managing the corresponding BSS. The passive scanning method can be applied when the second STA 4 is an AP transmitting a beacon frame. The other is an active scanning method. In this method, the first STA 2 to access a wireless LAN system, for example, an AP, first transmits a probe request frame. The second STA 4 having received the probe request frame transmits a probe response frame including a service set ID(SSID) of the BSS managed by the AP and information on capabilities supported by the AP. Accordingly, the first STA 2 can know existence of a candidate AP and a variety of information on the candidate AP from the received probe response frame.;COPYRIGHT KIPO 2010
