Abstract

PURPOSE:To allow a base station to collect a data of a terminal station efficiently without data collision by sending a specific signal in advance from the base station to the terminal station so as to take a reply timing. CONSTITUTION:A signal A aiming at collecting a data of a terminal station is sent prior to voice communication from a base station 1 to give a reply timing to terminal stations 2-4, which send the terminal station data to the base station 1 as a reply signal even during the communication with the base station 1 in the given reply timing. Thus, the base station 1 sends a signal aiming at collecting the terminal station data prior to the voice communication to the terminal stations 2-4 to give a reply timing to the terminal stations 2-4. Thus, the terminal stations 2-4 sends the terminal station data to the base station 1 in a given timing to allow the base station 1 to collect the terminal station data without data collision.
