TECHNIQUE FOR DETERMINING NEIGHBOURING RADIO RESOURCES BASED ON SIGNAL STRENGTH MEASUREMENTS

A technique for determining a list of neighbouring radio resources from signal strength measurements taken by mobile terminals is presented. Two or more signal strength measurements taken by the same mobile terminal at substantially the same time are grouped to a data set that associates, for each of two or more different radio resources of a given radio resource type, a measured signal strength with an identifier of the measured radio resource. An apparatus implementation of the technique presented herein is configured to analyze, using a similarity metric, similarity of a plurality of data sets. The apparatus is further configured to cluster the data sets, or information derived therefrom, based on data sets similarity so as to obtain multiple clusters representative of different radio locations and to determine, from each cluster, a radio resource set that defines a list of neighbouring radio resources for the radio location represented by that cluster. technique for determining neighbouring radio resources based on signal strength measurements
