Abstract

A wireless transmission device makes it possible to access the internet from a wireless LAN terminal, and notifies the state of wireless connection to a public wireless transmission network to the wireless LAN terminal, thereby alleviating uncertainty and disquiet on the part of the user when connecting to this network. The wireless transmission device detects the external network utilization information and notifies it to the wireless LAN terminal, and thereby the processing power of the wireless transmission device is enhanced, and uncertainty and disquiet on the part of the user when connecting to the public wireless transmission network are alleviated. If the wireless transmission terminal takes advantage of a mobile wireless transmission device for accessing the internet by using the public wireless transmission network, the communication burden which is imposed upon the public wireless transmission network is alleviated, and the internet access environment is enhanced. When a terminal device has made a connection request, an authentication section authenticates the terminal device, based upon authentication information which has been stored in a storage section in advance. And an encoding section executes an encoding procedure based upon a code which has been stored in the storage section in advance. By doing this, leakage of the authentication information is prevented. The wireless LAN terminal registers getting off reservation information and its own specific recognition code in advance. When a vehicle approaches a stopping point, the recognition code is verified and the getting off reservation information is notified to the wireless LAN terminal. By doing this, it is possible for the passenger who owns the wireless LAN terminal to get off at his desired stopping point.
