Self-Optimisation & self-ConfiguRATion in wirelEss networkS

Technical Approach

The SOCRATES overall project structure is shown in the Figure below. The directed arrows indicate the interactions between the different workpackages (thick arrow: main flow; thin arrow: feedback).

WP1: Project Management. This work package takes care of the overall management of the project’s operational and financial aspects and facilitates in- and external cooperation.
WP1 lead: TNO Information and Communication Technology

WP2: Use cases and framework for self-organisation. (Non-)technical requirements of the different components of self-organisation (self-optimisation, -configuration and -healing) will be derived from a list of use cases. These use cases define scenarios in which the application of self-organisation methods is envisioned in future access networks. In addition, assessment criteria for methods and algorithms for self-organisation are developed. Jointly, these aspects constitute the framework for the development of self-organisation methods in WP3 and WP4.
WP2 lead: Vodafone

WP3: Self-optimisation. Development of new concepts, methods and algorithms for self-optimisation of wireless networks that adapt to gradual changes in the radio network. Simulation tools will be applied to assess their performance, using the criteria and methodologies developed in WP2, and to assist in the understanding and further enhancement of the algorithms. Further-more, the required measurements, interfaces and protocols are specified.
WP3 lead: Ericsson AB

WP4: Self-configuration and self-healing. Development and validation of models and algorithms for self-configuration of newly deployed sites or technological features, and self-healing of incidental soft/hardware failures by means of local adaptation of radio parameters. In addition, newly required measurements and changes in interfaces to support the developed self-configuration and self-healing algorithms are specified.
WP4 lead: Nokia Siemens Networks - Germany

WP5: Integration, demonstration and dissemination. WP5 aims at:
1. The integration and attuning of the developed self-organisation methods (WP3-4) in line with the framework constituted in WP2.
2. A demonstration of the benefits from the self-organisation methods.
3. An assessment of the implications of the project results on radio network planning and operations, standardisation, technical/business opportunities, regulation and society.
4. The creation of an exploitation roadmap for the project results by identifying obstacles and enablers and determining a deployment roadmap for the use of self-organisation.
5. The dissemination of project results, including contributions to standardisation (3GPP) and industrial forums (e.g. NGMN), and the organisation of two dedicated workshops.
