METHOD AND SYSTEM FOR IDENTIFYING INTERFERENCE SOURCES IN A TELECOMMUNICATIONS NETWORK

摘要

A method and system for determining sources of downlink interference in a telecommunications network having offending cells and disturbed disposed therein. Initially, mobile traffic events in offending cells within the telecommunications network are identified. Disturbance events in disturbed cells within the telecommunications network are also determined. The identified mobile traffic events are then correlated with the identified disturbance events in order to detect possible sources of disturbance within the telecommunications network. A disturbance distribution for each disturbed cell within the telecommunications network is thereafter computed, when all identified mobile traffic events are correlated with the all identified disturbance events, thereby enabling network engineers to optimize the telecommunications network by minimizing downlink interference. The method and system are thus based on measurements and not predictions, so that the measurements take into account the behavior of all mobiles within the telecommunications network rather than a particular mobile event.
