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...

1 Loss System For a background review, I started the summer vacation scholorship by looking at loss systems. In a telecommunication context, this means that a new coming call is blocked (or lost) if there is no free circuits for that call. First of all, I made myself familiar with the notations. In a loss system, let C be the total number of circuits available, n be the number of circuits in us...

Today’s telecommunication service providers aim at reducing drastically the time for implementing a service in order to reduce the cost. Simultaneously, they want to provide a better quality of service. In this context, an identified solution at the Telecommunication Management Forum (TMF) was to propose a completely automated top-down management of the network using the definition of customer ...

This paper describes mobility management for the third-generation mobile networks. We focus on the evolution from General Packet Radio Service (GPRS) to Universal Mobile Telecommunication System (UMTS). In this evolution, the radio access network UTRAN has been introduced, and radio-related management is moved from the core network to UTRAN. We elaborate on how this architecture change affects ...

Teletraffic phenomenon in classical and new telecommunication networks can be more systematically described and different system-type problems can be effectively solved using fundamental concepts of systems and GSPS (General Systems Problem Solver) methodology. Basic presupposition is that general systems methodology is usable as a logicomathematical methodology in formulation, derivation and e...

Telecommunication networks have evolved over time as a result of technological advances, and network topologies and equipment have become increasingly complex. Expert systems are being successfully applied to the management of telecommunication networks. However, applying expert systems to network design is another especially beneficial yet still not very common approach. In this paper we propo...

Not available services or service interruption could have different impact to our social life. Emails or messages which are not delivered in a proper time-frame could lead to omit a meeting or a discussion with colleagues. Interconnected CPS in different domains, like autonomous driving, smart grids, Industry 4.0, needs a guaranteed and safe delivery of information. Nowadays distributed applica...

The management of both computer and telecommunication networks is an activity that has as main requirement the integration of heterogeneous systems. This work presents the Artemis tool, which has as key feature the capability to combine distinct systems of network management as well as their information concerning the network in order to exhibit them concisely and through a unique interface to ...
