1. A wireless information transferring system, comprising:

  • a plurality of wireless stations;

    a wireless terminal configured to be wirelessly connectable to the plurality of wireless stations;

    a router configured to connect the plurality of wireless stations and a network; and

    an authenticating server configured to authenticate the wireless terminal,wherein the wireless stations are configured to periodically transmit beacons that contain domain information identifying access networks that the wireless stations provide,wherein when a particular wireless terminal is in a handover condition requiring a handover from a present wireless station currently connected to the particular wireless terminal to a handover wireless station, the particular wireless terminal is configured to receive a beacon from the handover wireless station before the handover to obtain domain information of the handover wireless station from the beacon, to determine that authentication information should be transferred to the handover wireless station when the domain information of the handover wireless station is identical to the domain information of the present wireless station, or to determine that the authenticating server should newly perform an authenticating process relative to the particular wireless terminal after it is connected to the handover wireless station when the domain information of the handover wireless station is not identical to the domain information of the present wireless station,wherein when the determined result represents that the authentication information should be transferred to the handover wireless station, the authentication information is transferred to the handover wireless station, andwherein when the determined result represents that the authenticating server should newly perform the authenticating process for the particular wireless terminal after the particular wireless terminal is connected to the handover wireless station, the authenticating server newly performs the authenticating process for the particular wireless terminal after it is connected to the handover wireless station.
