INCOMING CALL CONNECTION CONTROL SYSTEM OF RADIOTELEPHONY EQUIPMENT

PURPOSE:To prevent the collision of response operation at an incoming call response by assigning a control channel at incoming call in time division the same number as that of mobile stations so as to send a response signal in the time slot assigned to the mobile station of response operation. CONSTITUTION:When a calling subscriber 1 makes a call to call the subscriber of a subscriber line 3 via a telephone exchange network 2, a call signal is sent from its associated exchange station to the said subscriber line 3 to form the incoming call state. When a fixed station 4 receives and detects the call signal, the call signal is sent through a control channel to the mobile stations 5, 6 at the same time. After the reception of the call signal, when both mobile stations 5, 6 make response in the 2nd frame, the processing to the mobile station 5 and the processing to the mobile station 6 are executed respectively in the time slot A and the time slot B of the 3rd frame. Thus, the response processing is applied to the mobile station 5 and the busy processing is applied to the mobile station 6, then the collision of the response operation at the incoming response is avoided.
