1. A method for dynamic network optimization in a simulcast communication system, comprising:
- hosting a simulcast communication session using a first base transceiver station (BTS) and at least one simulcast operating parameter (SOP) assigned to the first BTS, the at least one SOP selected to minimize time domain interference within at least a portion of an overlap area defined between the first BTS and a second BTS when signals from the first BTS and the second BTS are concurrently received within the overlap area;
monitoring at least one condition which is indicative of the potential occurrence of time domain interference among one or more of a plurality of mobile subscriber units participating in the simulcast communication session;
responsive to the monitoring, dynamically modifying the at least one SOP to optimize the performance of the network;
wherein the at least one SOP is a base station timing parameter which determines a transmit time of the first base station relative to the second base station for preventing time domain interference in an overlap area.

Abstract
In a simulcast communication session, at least one condition is monitored that is indicative of the potential occurrence of time domain interference at a plurality of mobile subscriber units. In response to such monitoring at least one simulcast operating parameter (SOP) is dynamically modified to reduce time domain interference experienced by one or more of the mobile subscriber units. The SOP is modified to minimize time domain interference within at least a portion of an overlap area defined between a first base transceiver station and a second base transceiver station.
