Title: Data communicating method and data communicating system
Inventor: NAITO YASUFUMI
IPC: H04W4/04
Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To transmit/receive information without the moving station of a specified vehicle existing between two points by referring to transmission destination information contained in a telegram in a moving station and to re-transmitting only the telegram for the other moving station except for a self-station. SOLUTION: The moving station becoming a repeating station receives information through an antenna 25 and a transmission/reception part 24 executes demodulation. A station recognition number reception part 23 judges whether the telegram is transmitted to the self-station or not. When the received telegram is judged that it is not for the self-station, modulation is executed again by using the transmission/reception part 24 and the telephone is transmitted again by using the antenna 25. When the opposite moving station receives the telegram, a destination number is recognized by a method similar to the moving station becoming the repeating station. When the received telegram is judged to be for the self-station, the telegram is analyzed.  An opposite station number for designating the moving station becoming a transmission destination is added to a telegram content and the telegram to be transmitted is sent. When the number of the self-station is not added to the telegram, the moving station receiving it is transmitted again.
