Abstract

An information communication system including an order station for transmitting a command signal to a mobile station, the mobile station including a memory for storing information representing that it has received the transmitted command signal from the order station, but has not responded to the command signal.

Claims

1. An information communication system comprising:

an order station including a transmission device for transmitting a command signal; and

a mobile station comprising a receiver for receiving the command signal transmitted by said order station, said mobile station further comprising means for transmitting reply information to said order station in response to receiving the transmitted command signal, a memory, a controller for storing to said memory information representing that said reply information has not been transmitted to said order station despite said mobile station receiving the transmitted command signal, and for storing to said memory information representing a position of said mobile station at which the transmitted command signal was received, wherein said controller stores the position information of said mobile station to said memory only when the reply information is not transmitted despite said mobile station receiving the transmitted command signal, and means for transmitting the information stored in said memory to said order station, wherein the position information stored in said memory is used to ascertain why reply information was not transmitted by said mobile station to said order station.

2. The information communications system as defined in claim 1, wherein said memory includes information representing an identifier for identifying the mobile station, and wherein said order station further includes means for receiving information transmitted from said mobile station, and monitor means for displaying received unique identifier information from the mobile station.

3. The information communication system as defined in claim 2, wherein said order station further includes a display for displaying information received from said mobile station, and a printer for printing the displayed information.

4. The information communication system as defined in claim 1, wherein said mobile station further comprises a timer for measuring a lapsed time between receipt of the command signal and transmission of information in response to the command signal.

5. The information communication system as defined in claim 1, wherein said mobile station further comprises a global position sensor receiver for receiving signals transmitted from at least one satellite.

6. The information communication system as defined in claim 1, wherein there are a plurality of mobile stations.

7. The information communication system as defined in claim 1, wherein said mobile station includes means for transmitting information stored in said memory when said mobile station transmits any information to said order station.

8. The information communication system as defined in claim 1, wherein said means for transmitting information stored in said memory transmits the position information and the information representing that said reply information has not been transmitted in such a manner that it can be determined whether an operator of said mobile station decided not to respond to the command signal.
