PURPOSE:To transmit/receive surely a data by allowing a command station to collect sequentially the data sent from a mobile station to the command station via an incoming talking channel between a younger number synchronizing signal and an old number synchronizing signal through an outgoing talking channel so as to facilitate the transmission/reception management at a subscriber station. CONSTITUTION:A data collection command is edited in an incoming control signal COT sent from a command station FS to a repeater stations BS via an incoming control channel fT0. When the repeater station BS receives the data collection command, incoming/outgoing channels fTi, fRi are set by the similar procedure to that receiving the call command of communication and then an outgoing polling signal PORj (j=0-n) is broadcast via the outgoing talking channel fRi. The command station FS and the mobile station MSn send a data according to the frame number data of the outgoing polling signal PORj. Since the transmission time zone is decided for the command station and each mobile station, the transmission/reception management at each subscriber station is facilitated and the data is sent/received surely. |
