1. A system for utilizing certain time slots of a radio channel frame as communication channels, each time slot capable of being used for transmitting message signals between a mobile station and a base station in a cellular telephone network, said system comprising:

  • message signal generating means for generating message signals to be transmitted in said time slots of said frame as a series of binary bits;

    synchronization word generating means for generating time slot synchronization words which are associated with each of said time slots, each time slot including channel indication information for indicating whether a time slot is a first type of channel or a second type of channel;

    frame producing means for producing a frame, which includes a plurality of said time slots, by allotting to each of said time slots a message signal and an associated synchronization word;

    transmitting means for transmitting said frame;

    receiving means for receiving said transmitted frame;

    detecting means for detecting said channel indication information; and

    determining means determining whether each of said time slots is to be utilized as a traffic channel or a control channel in response to detection of either said first type of channel or said second type of channel.
