Abstract
A priority and preemption method for performing a priority and preemption process includes the steps of satisfying a resource acquisition request from a reserve pool for an external system, and when the resource acquisition request cannot be satisfied from the reserve pool, requesting additional unused frequencies, and when the additional unused frequencies are not available, requesting to preempt active calls. The method also includes the step of replenishing the power and the frequencies received from the frequency controller, the data hub and/or the independent operations controller when the frequencies are no longer needed by the priority and preemption system.
