Abstract
A method of reducing base station overloading consists of a series of sequential steps, beginning with reducing the decibel size of the handover window, base station exclusion, only one base station being excluded at a time, mobiles not in soft handover not being excluded, and if more than one base station in the active set is overloaded, excluding the station which has the strongest received power from the active set.
Claims7
A method of reducing base station overloading, comprising:
- prioritizing each base station in an active set of base stations in soft handover with a mobile, said active set including a base station nearing overload;
- and
- removing a base station from said active set by reducing a handover window size for said mobile, said removing step comprising
- reducing said handover window size based on a ratio of powers corresponding to a link between said mobile and said mobile's strongest base station and a link between said mobile and said base station nearing overload,
- controlling said reducing step so as to remove only one base station at a time until said base station nearing overload is removed from said active set.
