Self-Optimisation & self-ConfiguRATion in wirelEss networkS

Project Objectives

The general objective of SOCRATES is to develop self-organisation methods in order to optimise network capacity, coverage and service quality while achieving significant OPEX (and possibly CAPEX) reductions. Although the developed solutions are likely to be more broadly applicable (e.g. to WiMax networks), the project primarily concentrates on 3GPP’s LTE radio interface (E-UTRAN). In more detail the objectives are as follows:

• The development of novel concepts, methods and algorithms for the efficient and effective self-optimisation, -configuration and -healing of wireless access networks, adapting the diverse radio (resource management) parameters to smooth or abrupt variations in e.g. system, traffic, mobility and propagation conditions. Concrete examples of the radio parameters that will be addressed include: power settings, antenna parameters, neighbour cell lists, handover parameters, scheduling parameters and admission control parameters.

• The specification of the required measurement information, its statistical accuracy and the methods of information retrieval including the needed protocol interfaces, in support of the newly developed self-organisation methods.

• The validation and demonstration of the developed concepts and methods for self-organisation through extensive simulation experiments. In particular, simulations will be performed in order to illustrate and assess the established capacity, coverage and quality enhancements, and estimating the attainable OPEX (/CAPEX) reductions.

• An evaluation of the implementation and operational impact of the developed concepts and methods for self-organisation, with respect to the operations, administration and maintenance architecture, terminals, scalability and the radio network planning and capacity management processes.
