At this time, telecommunication networks are present everywhere. These networks are not only rather complex, but they are also made up of different components. That is the reason telecommunication network management (TNM) is so relevant. This paper deals with two important aspects of telecommunication network management: managed objects and expert system rules. Definition of objects is based on...

To solve the problems of modeling telecommunications networks currently used by a large number of different methods. All of them can be divided into two classes1-5. First class combines methods of physical modeling in which, instead of the real system uses its simplified physical counterparts. In view of the significant limitations of these methods, they are rarely The second class includes met...

The objectives of the paper is to review the conflicting requirements and needs of existing telecommunication network testing approaches, services and equipment, in order to provide a simple but powerful solution that allows automated and standardized testing activities. We present in the paper a progressive transition from the current proprietary practices, to a distributed and fully TMN compl...

Even though the radio was invented more than 100 years ago, it has not been until 10-15 years ago that widespread use of wireless communications has begun. While before then it was mainly used by police and military, now the capability of communicating without being constrained to a fixed physical location is within everyone’s reach. The booming industry which has been growing at such an astoun...

Nowadays telecommunication systems are growing more and more complex, generating huge amount of alarms that cannot be effectively managed by human operators. The problematic is to detect in real-time significant combinations of alarms that describe an issue. In this article, we present a powerful heuristic algorithm that constructs alarm patterns dependency graphs. More precisely, it is able to...

Fixed Mobile Convergence is an important challenge for telecommunication operators given the heterogeneity of access networks technologies and the variety of terminals. Fixed Mobile Convergence, which introduces the concept ‘Being always best connected’, is considered to be the next step in the evolution of telecommunication networks and should increase the operators’ revenues. In order to enfo...

We address the problem of failure diagnosis in discrete-event systems such as telecommunication networks. We propose to extend the decentralized diagnosis approach proposed in (Pencolé 2000) in order to use it in an incremental way. The incremental approach is needed in order to provide on-line diagnosis and assist supervision operators. The difficulties about the incremental decentralized diag...
