1. A method of time-slot allocation for a communication in a time division multiple access (TDMA) communication system which allocates one time-slot for a low transmission speed communication and a plurality of time-slots for a high transmission communication in a TDMA frame, said method comprising the steps of:

  • detecting a request for a new communication;

    examining whether there exist any high transmission speed communications currently communicating in the TDMA communication system, if the number of idle time-slot required for the new communication are not available;

    if there exists at least one high transmission speed communication currently communicating in the TDMA communication system, selecting one of the high transmission speed communications, and instructing a mobile terminal involved in the selected high transmission speed communication to suspend communication due to time-slot reallocation;

    releasing at least one time-slot from a plurality of time-slots in the selected high transmission speed communication;

    notifying the mobile terminal to resume communication with a reduced number of time-slots without using the at least one time-slot; and

    allocating the at least one released time-slot to the new communication requested.
