Self-Organizing Networks (SON) aim at automation of network parameters to make the planning, configuration, management, optimization and healing of mobile radio access networks simpler and faster, and thus also more cost efficient. E.g. Mobility Robustness Optimization (MRO) targets at automatic detection and correction of handover (HO) parameters, either at local (cell or cell-pair level) or global (network) scope. Design of SON algorithms may be a complex task due to multiple related configuration parameters, heterogeneous nature of network deployments, UE mobilities and load. Magister Solutions Ltd. has designed and implemented simulation framework called Self-Organizing Simulator 3 (SonS3) in a joint project with Elisa Corporation, a major Finnish network operator, which also offers its own SON solution called Elisa SON (https://www.elisa.com/elisason/). SonS3 makes use of real network data to enable an accurate performance analysis of mobility related SON use cases.
The project results are presented in an article called “SonS3: A Network Data Driven Simulation Framework for Mobility Robustness Optimization” by Frans Laakso, Jani Puttonen, Janne Kurjenniemi, Biying Wang, Di Zhang, Furqan Ahmed and Jarno Niemelä. The article is going to be presented in IEEE VTC 2018 conference (http://www.ieeevtc.org/vtc2018fall/) in August 2018 in Chicago, USA.
