An experimental system for SON verification

In a mobile Self-Organizing Network (SON) the usage of a SON coordinator is necessary to preclude the execution of conflicting SON function instances. Typically, such a coordinator is accountable for conflict prevention and resolution and does not take into consideration that the activity of function instances may induce an undesired network behavior. In this paper, we propose an experimental system for the verification of Configuration Management (CM) changes induced by the activity of SON function instances. The main part of this system is the SON verification function which is triggered when CM change requests get acknowledged by the SON coordinator. It analyses the resulting Performance Management (PM) data and in case it detects an undesired network behavior it sends a request to the coordinator to undo the responsible changes.
