AUTOMATIC RETRANSMISSION METHOD

摘要

PURPOSE:To surely attain re-transmission of a slip whose transmission is disable without need of the confirmation of the operator by re-transmitting the slip whose transmission is disable stored in a central processing unit to a mobile station radio equipment automatically when the radio equipment of the mobile station confirms a select call reply or talking. CONSTITUTION:When data transmission from a command station radio equipment 3 to a mobile station radio equipment 2 mounted on a vehicle 7, a slip whose transmission is disable is stored in a central processing unit 4 as a disable slip. When the radio equipment 2 receives a select call signal from the radio station 3 in this state, the radio equipment 2 sends a select call acknowledge to the radio equipment 3 conversely. The unit 4 identifies a vehicle number written in the select call acknowledge data and sends the data being the disable slip to the vehicle stored in itself from the radio equipment 3 to the radio equipment 2 again. Thus, efficient re-transmission is attained without the operation of the operator at the command station side.
