Self-configuration, -optimisation and -healing in wireless networks

This paper presents a vision on the use of self-organisation methods (self-optimisation, self-configuration, and self-healing) as a promising concept to automate wireless access network planning, deployment and optimisation. The major intentions are to improve network coverage, resource utilisa-tion and service quality, and to substantially reduce operational expenditure. The funda-mental drivers for the deployment of self-organisation methods are discussed, consid-ering both the technology and the market per-spective. The distinction and interactions be-tween the different components of self-organisation are outlined and the expected gains are discussed. An overview of the cur-rent state of the art in this field is followed by a formulation of the main challenges in the de-velopment of effective and reliable methods for self-organisation. Finally, a brief overview of the European SOCRATES project is given, which recently started to overcome these chal-lenges.
