PURPOSE:To communicate with the caller side by storing a message code or the like into a memory when the call comes its end without reply at the time of receiving a signal sent by adding a selective call control signal with the message code to detect an incoming call in absence. CONSTITUTION:Various commands from a call station are converted into message codes 10 by the key input of an operation section 12, and the code is sent to an incoming station from a transmission section 14 as a selective call control signal 8 together with a call station number code 9. A radio equipment of the incoming station receives the signal 8, a message exists at the select call and it is judged that the call is ended without changeover of press-to-talk, then the message, a call station number, and a time data from an internal timer are stored in the memory of a logic section 11. In applying a call command of the memory by the depression of the press-to-talk or the like, the message in absence, a call station number and the time data are read, they are communicated from the incoming station to the call station, and the radio line is used efficiently without requiring the incoming station for many times.
