Common radio resource management method in a multi-RAT cellular telephone network

A method for common radio resource management in a mobile radio communication network employing different radio access technologies that overlap over a geographic area and which are subdivided into cells belonging to domains of controllers which are connected to each other in overlapping or adjacent domains and to a core network by means of relevant interfaces, the method being suitable to be carried out for each controlled cell by the respective controller through the following method step:

• a) starting from acquired information about Qos and throughput of all active connections with served mobile terminals, calculating traffic-related Information Elements, separately for uplink and downlink, for use in planning at least one of handovers and cell reselections;
• b) including said Information Elements in management messages forwarded to the controllers of different cells and to one considered either of a same or different technology;
• and
• c) checking said Information Elements coming from other controllers in order to decide either of issuing or preventing at least one handovers and cell reselection commands towards a neighboring cell;
• wherein the traffic-related Information Elements include indications of bearer services availability in the cell in terms of a maximum bearer services bitrate, either guaranteed or not guaranteed, that can currently be provided for a given bearer service, and wherein the maximum bear service bitrate indicates whether a bear services is currently unavailable;
• and
• wherein the bear services availability is subdivided into the following standardized Quality of Service classes, the classes including:
• Conversational, Streaming, Interactive, and Background.
