ABSTRACT:
GERAN Cell Capability indicated in a bit of an Information Element is modified to indicate whether a neighbor GERAN cell belonging to a radio access technology (GSM) supports packet switched (PS) handover or not so that the serving radio network controller can be in possession of such information before deciding whether to attempt PS handover to the cell of the GSM network and thereby avoid unnecessary signaling in case such a handover is not possible and to thereby allow the serving radio network controller to consider some other target cell or some other solution than triggering PS handover toward that GSM cell.
