1. In a TDM wireless communication system that includes a plurality of communication units arranged into at least one communication group, a plurality of wireless communication resources, and a central controller that allocates the plurality of wireless communication resources among the plurality of communication units, a method for providing caller interrupt, the method comprising the steps of:

  • a) transmitting, by a first communication unit of the at least one communication group, a request for a group call;

    b) upon receiving the request, allocating, by the central controller, a first inbound wireless communication resource, a second inbound wireless communication resource, and an outbound wireless communication resource;

    c) transmitting, by the first communication unit via the first inbound communication resource, primary voice signals;

    d) receiving, by the central controller via the first inbound wireless communication resource, the primary voice signals;

    e) retransmitting, by the central controller, the primary voice signals via the outbound wireless communication resource;

    f) transmitting, by a second communication unit of the at least one communication group, interrupt voice signals on the second inbound wireless communication resource while the first communication unit is currently transmitting;

    g) receiving, by the central controller via the second inbound wireless communication resource, the interrupt voice signals;

    h) summing, by the central controller, the interrupt voice signals and the primary voice signals to produce summed voice signals; and

    i) transmitting, by the central controller, the summed voice signals on the outbound wireless communication resource, thereby providing caller interrupt.
