A Common radio resource management method is performed in a mobile radio communication network employing different radio access technologies that overlap over a geographic area subdivided into cells belonging to the domains of respective controllers which are connected to each other in overlapping or adjacent domains and to a core network by means of relevant interfaces. The controllers calculate new traffic-related Information Elements to be exchanged over the existing interfaces to the aim of planning handovers and/or cell reselections towards adjacent cells either of the same or different RAT. Cell capabilities and mobile terminal capabilitiess being also specified by respective IEs. Diversely from the conventional traffic-related IEs based on Cell Load parameters or Free Capacity, the new IEs include indications of the “availability” of bearer services in the cell in terms of maximum bitrate, either guaranteed or not guaranteed, that can currently be allowed to each bearer service.
