Abstract
A wireless communications systems for servicing mobile subscribers which dynamically optimizes the absolute number of channels reserved for use only as guard channels to minimize the blocking of handoff as well as new calls even under widely varying traffic and mobility conditions. This is accomplished by periodically first incorporating values, representative of traffic and mobility data typically collected in cellular systems, obtained over a given period of time, into an equation developed by the present inventors and calculating the number of guard channels needed to obtain assumed values of new and handoff call blocking; second changing the number of guard channels to the calculated value; and then third gathering data for a new period of time before returning to the first step.
