Management server, terminal, and method for providing and applying wireless lan security policy by participating in multiple access points

A management server for providing wireless local area network (LAN) security policy by participating in multiple access points (APs), the management server comprising:

• a communication module configured to transmit/receive data to/from multiple APs having overlapping coverage areas and a terminal for wirelessly accessing any one of the multiple APs;
• a memory configured to store a control program for wireless access of the terminal to any one of the multiple APs;
• and
• a processor configured to issue and store a token for opening a wireless LAN data channel to each of the multiple APs on the basis of reception time points of terminal information transmitted from the multiple APs, by executing the program stored in the memory, and to, upon receiving a token request for opening a wireless LAN data channel to an AP to be accessed, selected by a terminal among the multiple APs, distribute, to the terminal, a token of the AP to be accessed corresponding to the token request,
• wherein the terminal requests access to a wireless LAN data channel of the AP to be accessed, on the basis of the token.

A method in which a management server provides wireless local area network (LAN) security policy by participating in multiple access points (APs), the method comprising:

• a step of receiving terminal information of a terminal, which is acquired in a process of scanning broadcasting information of multiple APs, from each of the multiple APs;
• a step of issuing and storing a token for opening a wireless LAN data channel to each of the multiple APs on the basis of reception time points of the terminal information;
• a step of receiving a token request for opening a wireless LAN data channel to an AP to be accessed, selected by a terminal among the multiple APs;
• and
• a step of distributing, to the terminal, a token of the AP to be accessed corresponding to the token request.
