<p>An apparatus and method for detecting a data transmission mode of an access point AP (10) in a wireless terminal (20) is provided. When the AP (10) switches the data transmission mode in a state where a Wi-Fi wireless link is connected between the AP and the wireless terminal or not, the AP transmits (S106) the mode switched information to the wireless terminal (20) with the information carried on the arbitrary field in any one of the Beacon, Probe Response, Association Response messages, and the wireless terminal compares the mode switched information included in the transmitted message with the currently set data transmission mode, switches the mode, attempts re-connection to the AP in the switched mode, and performs the Wi-Fi wireless link connection (S107,S108) with the AP (10). Thereby, it is possible to provide data telecommunication services without interruption.</p> |
