Self-Managemement for Unified Heterogeneous Radio Access Networks


The SEMAFOUR project will develop a unified self-management system enabling network operators to holistically manage and operate complex heterogeneous mobile networks. The ultimate goal is to create a management system that enables an enhanced quality of user experience, improved network performance, improved manageability, and reduced operational costs.

The SEMAFOUR project has two key objectives.

  • The first objective is the development of self-organising network (SON) functions that provide a closed control loop for the configuration, optimisation and failure recovery of the network across different radio access technologies (RATs, e.g., UMTS, LTE, WLAN) and cell layers (macro, micro, pico, femto). Such coordinated adaptation of radio (resource management) parameters in different RATs and cell layers is imperative for the global optimisation of network performance.
  • The second objective is the design and development of an integrated SON management system, which interfaces between operator-defined performance objectives and the set of multi-RAT / multi- layer SON functions. This will provide a unified view on the performance of the complex heterogeneous network environment and allow its efficient control and operation. This important new management system enables operators to move their operational focus towards a higher, more global level, transparent to the specifics of the underlying network technologies and network layout.

The SEMAFOUR consortium

The SEMAFOUR consortium consists of two of the world's largest mobile communication equipment vendors (Ericsson and Nokia Siemens Networks), two leading mobile operators (Orange/France Telecom and Telefonica), an SME developing support tools for mobile network planning and operations (Atesio) and three research organisations (IBBT/iMinds, TNO and TU Braunschweig) that have a proven record in contributing to scientific developments and successfully cooperating with the mobile industry.
FP7 SEMAFOUR is a follow-up project of FP7 SOCRATES (2008-2011).
