Verfahren zur Bestimmung einer Übergabe in einem mehrzelligen Kommunikationssystem

摘要

The decision whether to hand off an ongoing call to a macrocell or a neighbouring microcell is made on the basis of how fast the mobile station is travelling. The speed of the mobile station is determined by counting the number of handoffs which have occurred in a preceding period. Another method of determining the speed of the mobile is to count the number of measurement reports occurring in a preceding period. If the speed is above a certain threshold, handoff is to a macrocell rather than a microcell.
