1. A method of providing an accelerated response to a push-to-talk origination message in a dispatch system, said dispatch system having a plurality of remote units, a plurality of base stations, and a mobile system controller, said method comprising the steps of:

  • pre-allocating a first set of equipment to support a push-to-talk connection at each of said plurality of base stations;

    pre-allocating a second set of equipment to support said push-to-talk connection at said mobile system controller;

    receiving at a first base station a push-to-talk origination message from a first remote unit; and

    transmitting from said first base station directly in response to said push-to-talk origination message a page to said first remote unit directing said first remote unit to establish communication through said first and second sets of equipment wherein the step of pre-allocating said second set of equipment comprises the step of pre-allocating at least one mobile system controller selector to route calls between a switch and a CDMA interconnect subsystem.
