Abstract

A method of reducing blockages and call interruption in handling over calls in a cellular mobile radio system. When the signal strength from a base station to a mobile and vice versa falls below a given value the handover shall take place to another base station. In order that the call will not be interrupted, a smaller number of channels are reserved, so-called rescue channels, from the ordinary channels in the system. The rescue channels can be fixed or dynamic for a given base station.
