Future wireless networks will experience a continuous growth regarding the number of network elements with increasingly complex interrelations between the configuration of multiple network elements. Another trend is the seamless integration of multiple radio technologies into a single wireless network. Both developments increase network management complexity and require new management concepts with a very high degree of automation. For this purpose, a novel management approach based on a combination of workflow and policy technologies is presented. The goal is to simplify and automate management tasks in mobile networks in order to raise the state of self-organization while the network still remains under control of the operator. The approach provides the means for a dynamic system to automatically adapt to context changes. Moreover, an experimental system is presented for the purposes of concept validation and evaluation along with a real world use case.

Specification and Refinement of Domain-Specific ECA Policies

Policy-based management is a flexible approach for the management of complex systems as policies make context-sensitive and automated decisions. For the effective development of policies it is desired to specify policies at a high level of abstraction initially, and to refine them until they are represented in a machine-executable way. We present an approach for the specification and the automated refinement of domainspecific event-condition-action (ECA) policies. Domain-specific policies use domain-specific concepts within their event, condition, and action parts. The approach is generic as it can be applied to any domain and supports a flexible number of abstraction layers. It is applied to the network management domain and demonstrated with policies for signal quality management in a mobile network.

Abstract-Policy-based management is a flexible approach for the management of networks as policies make contextsensitive and automated decisions. For their effective development it is desired to specify policies at a high level of abstraction initially and to refine them until they are represented in a machine-executable way. We present an approach that uses models to specify event-condition-action (ECA) policies at different abstraction layers and that uses model transformations to refine them in an automated way. A relational algebra is used to formally validate the models and define the semantics of the refinement process. One benefit of the approach is the automated policy refinement at runtime. Changes at the high-level models are automatically reflected in their low-level implementation through refinement. This allows to manage a system at a high level of abstraction. The approach is applied to the network management domain and demonstrated with policies for physical cell identification (PCI) in a mobile network. It can also be applied to other domains and supports a flexible number of abstraction layers.
