Abstract
An access point (AP) measures a congestion level of a transmission channel representing a collision probability between frames at a channel busy duration and transmits the congestion level to a terminal. Therefore, the terminal extracts a congestion level that is included in a frame that is received from the AP through a scan process for searching for an AP to which the terminal is to connect. The terminal selects an AP to connect from at least one AP based on the extracted congestion level of the transmission channel.
