Abstract

A method of moving a station in a wireless LAN, includes the step of: a station recognizing that a first access point of a first communication area is connected thereto, when the station is located in the first communication area, and storing corresponding connection information in an initial access point record area of its storage. The station requires the first access point to cancel the connection with the station, when the station moves from the first communication area to second communication area. The station requires a second access point of the second communication area to be connected thereto, when the station moves to the second communication area. Then, the second access point registers the station on the connection station list stored in its storage. The station transmits connection information about the first access point, stored in its initial access point record area, to the second access point, to inform the second access point that the station moved from the first communication area.

Claims

1. A method of moving a station in a wireless local area network (LAN), comprising the steps of:

a station recognizing that a first access point of a first communication area is connected thereto, when the station is located in the first communication area, and storing corresponding connection information in an initial access point record area of its storage;

the station requiring the first access point to cancel the connection with the station, when the station moves from the first communication area to a second communication area;

the first access point cancelling the connection with the station, deleting the station on a connection station list stored in its storage, simultaneously, registering the station on its connection cancellation station list;

the station requiring a second access point of the second communication area to be connected thereto, when the station moves to the second communication area;

the second access point registering the station on the connection station list stored in its storage;

the station transmitting connection information about the first access point, stored in its initial access point record area, to the second access point, to inform the second access point that the station moved from the first communication area;

the second access point registering the information about the first access point of the first communication area where the station was located in its storage, and then informing the first access point that the station moved to the second communication area of the second access point; and

the first access point registering the second access point in a station destination information record area included in its storage.
