Abstract EN:

Next Generation Networks (NGN) are designed to allow rapid delivery of Next Generation Services (NGS) that are available in any place, at any time, on any device, and through any access network. One of the most important NGN challenge arises from the management operations of those services and their corresponding new business models. In fact, adding new functionalities or new services requires the adaptation of the legacy Operations Support Systems which takes on average two years to be achieved. Moreover the service customization is a new feature required by the customer of the Next Generation Services, and the generic management systems and the rigid management operations are no longer suitable to handle it. The goal of our research is to make services self managed in order to simplify the complexity of the management systems and to enable the distribution of management tasks amongs them. We subdivide management tasks into a set of goals achieved by the Self Managed Next Generation Services individually or in cooperation. For that we enhance each service with “Operations Manager”. The Operations Manager is the entity we define and develop, based on the autonomic principles to handle the service delivery chain and so the management tasks. Alongside the state of the art about the Next Generation services, the emerging management pardigms, the semantic aspects of management, we mainly aim to answer the following questions : - What are the requirements to build Self-Managed NGS, relying on the NGS architectures defined in the ETSI-TISPAN specifications and in the OMA specifications, with Autonomic principles? - What is the role of semantic and ontology for the management of the Next Generation services? - How could such Self Managed NGS be implemented?
