Abstract

A handover initiation system for a cellular radio network comprises means for determining both the distance of a mobile user from a cell base station based on propagation delay techniques and means for measuring the signal strength to determine the path taken by the mobile user. In a busy area microcells are constituted by single streets. The propagation of ad-joining streets in a larger macrocell can be distinguished from the propagation, characteristics of the street constituting the micro-cell such that the handover initiation of a mobile user within one of the surrounding streets can be determined.
