Network Panel

Hannover scenario with 65 LTE-1800 base stations in a 3 km x 5 km area including 2000 realistic users in 3 different user classes.

The colour of a cell indicates relevant information like load situation, cell configuration, handover events etc.

SON Function Parameter Settings: Means to modify SON Function behaviour by applying configuration sets

Context: Current PM/CM/ FM data + NW Context

SON Function Model: Input KPI targets; output configuration, parameter settings, … Mapping: System objectives to SON Function parameter settings

KPI Panel

Charts of the KPIs related to network load and the service quality experienced by the active users.

Operator Panel

Adaptation of operator objectives and their priorities and definition of context information (e.g., the current time or the base station location) according to which these objectives shall be activated.

SON Objective Manager

Performs an automated transformation of technical objectives into a SON Policy. Therefor it creates a state space over all contexts, where all KPI targets are mapped to the best suited Configuration sets for the implemented SON Functions (for further information see [1]).

The appropriate Configuration Set is selected by a Policy System which allows to dynamically react on changes in the context, according to the SON Policy. [1] C. Frenzel, S. Lohmüller, L.C. Schmelz, “Dynamic, Context-Specific SON Management Driven by Operator Objectives” in IEEE/IFIP Network Operations and Management Symposium (NOMS 2014), Krakow, Poland, May 2014

KPIs:

• Network Throughput

• Network Load • Number of

Unsatisfied Users

• Handover Performance
