Abstract
To reduce time to point a directional wireless portable terminal (WPT) to an access point (AP) when data is downloaded from the AP to the WPT, a user points the WPT to the AP, performs a first operation and transmits a request of authentication and download to the AP. The AP requests a server to perform the authentication and the download. The server transmits information on a current situation to the AP. The AP calculates time required until the download can be started based on content capacity and the like and transmits information on the calculated time to the WPT. The WPT displays countdown until the download can be started. During that time, the server performs the authentication and, if successful, delivers content to the AP. When the download can begin, the user performs a second operation and transmits a request of re-authentication and download to the AP.
