Abstract
In a wireless communication system, radio resources are dynamically assigned among a plurality of intercoupled base stations based upon historical loading to reduce both localized and system interference. A plurality of loading intervals are first determined that span a loading interval sequence. The loading intervals may correspond to time based periods such as fifteen-minute, thirty-minute, hour or other time intervals. The loading interval sequence may correspond to a weekday, a weekend day or such other loading period within which loading resembles a pattern. Based upon estimated loading for the loading interval, a number of channels required to service load for the loading interval are made to meet a minimal service level is determined. An initial assignment of channels among the cells/sectors of the base stations of the wireless communication system is then made to satisfy localized radio interference criteria. Such an assignment will typically be made to preclude local reuse of channels. Then, the assignments are reconsidered from the standpoint of system interference and the channels are reassigned to minimize system interference. In reassigning channels among the cells/sec…
