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.
