NGN Management with NGOSS Framework-Based IMS Use Case

Conference paper
Part of the Lecture Notes in Computer Science book series (LNCS, volume 10542)


The success of a telecom operator depends on several criteria such as the ability to offer an improved architecture management. The IP Multimedia Subsystem (IMS) has emerged to allow to telecom operator to unify all access technologies namely wireless, wire line, and extended to agnostic access. However, the services provided by the IMS require Quality of Service (QoS) management with Service Level Agreement (SLA) negotiation which can be achieved by several solutions. Among these solutions, we propose the use of the New Generation Operations Systems and Software (NGOSS) Framework which is a functional framework used to model and analyze networks and services activities. To better understand the relationship and the projection of NGOSS Framework and IMS platform, the article proposes a new architecture of monitoring IMS services with correction of the Quality of Service (QoS) degradation. The performance of the proposed architecture is evaluated by experiments.
