Abstract [en]

The present invention relates to a method, call handling server (18), local wireless network (10) and computer program product for performing vertical handover of a wireless voice connection, which is a part of a voice connection set up between a portable communication (22) device and another device. The network comprises a number of access points (20) and the call handling server (18) for controlling voice connections to the portable device. The server comprises a control unit (24) that determines a handover situation for the wireless connection to the portable device based on a set of handover factors that comprise the position and movement of the portable communication device in an area of the local network and structural layout information of the area together with knowledge of where in this area there is insufficient coverage.
