Abstract

In a method in a central node of a cellular radio network the central node is adapted to deciding if a mobile station connected to the cellular radio network via a first radio access technology controlled by the central node is to be moved to another radio access technology when a circuit switched call of the mobile station is ended. It is assumed that the cellular radio network is adapted to use a fallback to circuit switched procedure. First it is decided that a CS call for a particular mobile station has ended. Then in it is checked if the CS call was the result of a fallback to CS procedure. The central node then decides if the mobile station is to be moved to another radio access technology based at least partly on the, i.e. if the CS call was a result of a CS fallback procedure.
