Abstract:
A mobile communication system comprising:an information processing center apparatus;a switching station for controlling a connection of a wireless line;a communication network for connecting said information processing center apparatus to said switching station;a mobile station for performing a data communication via the wireless line between said switching station and the own mobile station;a protocol quasi-terminating apparatus provided between said communication network and said switching station, for detecting as to whether or not a line connected between said communication network and said switching station is interrupted, and for quasi-terminating a protocol used to said communication network, and another protocol used to said mobile station in the case that said line is interrupted;an information processing terminal for transmitting/receiving data between said information processing center apparatus and the own information processing terminal; anda wireless line connection control apparatus provided between said mobile station and said information processing terminal, for transferring to said mobile station an instruction to interrupt the wireless line between said switching station and said mobile station in the case that no data is transmitted/received between said information processing terminal and said mobile station, and also for transferring to said mobile station an instruction to connect said interrupted wireless line in the case that the data transmission/reception is commenced between said information processing terminal and said mobile station,wherein said protocol quasi-terminating apparatus includes:a mobile station-sided protocol terminating unit for judging as to whether or not the line between said communication network and said switching station is interrupted, and also for quasi-terminating a protocol used to said mobile station when a protocol termination instruction is entered to said mobile station sided protocol terminating unit;a communication network-sided protocol terminating unit for quasi-terminating a protocol used to said communication network when a protocol termination instruction is entered into said communication network-sided protocol terminating unit; anda protocol terminating/matching control unit for transmitting a protocol termination instruction to both said communication network-sided protocol terminating unit and said mobile station-sided protocol terminating unit in the case that the detection result of said mobile station-sided protocol terminating unit indicates that the line is interrupted.
