ABSTRACT:
An efficient method of time-slot allocation for a communication in a time division multiple access (TDMA) communication system which allocates one or more time-slots in a TDMA frame is provided. When new call request occurs, availability of idle time-slot for the communication is examined. If there is not enough idle time-slot to be allocated for the new call, it is examined whether there is high transmission speed communication using a plurality of time-slots. When any of the high transmission speed communications exist, time-slots are shared by newly requested communication and the high transmission speed communication using a maximum number of time-slots among the high transmission speed communications. Transmission speed adjustment is performed for such high transmission speed communications sharing a part of time-slot. The probability of occurence of call loss is decreased by this method.
