Abstract
While the presently operable communication infrastructure is used, a wireless line is connected only during data transmission/reception. When no data is transmitted/received between an information processing terminal and a mobile station, a wireless line connection control apparatus instructs to the mobile station that the wireless line is interrupted. When a protocol quasi-terminating apparatus detects that the line is interrupted, this protocol quasi-terminating apparatus quasi-terminates the protocol in order that a logical link established between the communication network and the mobile station is not disconnected. As a result, the wireless line can be connected only when the data is transmitted/received without requiring user's operation.
