Överlämningshanteringssystem för cellulärt nät

摘要

A handover management system for a hierarchical cellular network (eg GSM) in which handover between levels is controlled on the basis of the rate of change of candidate cell identification data reported back to a serving base station by a mobile unit. Rapid changes identify a mobile station which is moving relatively rapidly and is accordingly better allocated to a higher level base station than to a lower level station from which handover may soon be necessary again. The levels may be macrocells and microcells. Handover may be to the cell which has been a candidate for the longest time.
