A control signal transmission system for mobile radio communications uses a plurality of control channels extending between a plurality of mobile units and at least one control center. The control center transmits system information signals and paging signals during individually associated time frames. The mobile units transmit response signals corresponding to the paging signals by transmitting to the control centers through the control channels. At least one frame of the system provides for a transmission of responsive information signals, following each frame including the paging signals. Each of these response signals includes an identification number of the replying mobile unit. |
