Common radio resource management method in a multi-RAT cellular telephone network
First Claim
1. 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.

Abstract
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.
