SIMILARITY METRIC CUSTOMIZED TO RADIO MEASUREMENT IN HETEROGENEOUS WIRELESS NETWORKS AND USE THEREOF

摘要

The present invention relates to a similarity metric customized to radio measurement in heterogeneous wireless networks and to the use of the similarity metric. Radio measurement values reflecting radio access conditions during different measurement time intervals for at least one mobile terminal having radio access to the heterogeneous multi-carrier network are aggregated into radio measurement scans. Further, for every radio measurement scan related radio measurement configurations prevailing at the time of measurement of the corresponding radio measurement values are aggregated into a radio measurement configuration scan. Then the similarity metric is calculated for a pair of radio measurement scans to generate knowledge on radio coverage in the heterogeneous wireless network in a customized manner through reference to radio measurement configuration scans associated with the pair of radio measurement scans for which similarity metrics is to be calculated.
