This paper describes a search tool that currently is being used by British Telecommunications engineers to access a technical repository. Our search tool is composed of two major components: an ontology assisted query understanding/rephrasing and a keyword based search that has an indexer enhanced with automatic text classification. Although the ontology was built for engineers it is a good bas...

This paper defines a three-dimensional architectural framework, named Technology and Information Platform (TIP), to effectively handle the architecture complexity and manage the architectural assets of enterprise information systems in a service-oriented paradigm. This comprehensive model is composed of a Generic Architecture Stack (GAS) comprising a stack of architecture layers, and the contex...

Wireless telecommunications represent an important asset for public protection and disaster relief (PPDR) organizations as they improve the coordination and the distribution of information among first responders in the field. In large international disaster scenarios, many different PPDR organizations may participate to the response phase of disaster management. In this context, PPDR organizati...

The telecommunications environment is changing its face towards an open market of information services where the vision is "information any time, at any place, in any form". Within this electronic market the aspects of service customization and instant service provision are of fundamental importance. In this context a new paradigm is gaining momentum, referred to as "Intelligent Agents". This p...

Abstract TINA (Telecommunications Information Networking Architecture) concepts and principles are introduced with the objective of correcting problems of centralized service control and service data model existing in IN (Intelligent Network). Now, TINA has been designed with the goal to offer an universal vision of telecommunications services, it answers to the increasing needs of fast develop...

The communication focuses on the educational environment for teaching "Digital Speech Processing" at undergraduate, graduate and PhD levels in the Department of Telecommunications from Technical University of Cluj-Napoca, Romania. Emphasis will be done to reveal particular successes and drawbacks in order to set up and to develop a modern curriculum during the last four years. This educational ...

his book contains the highlights of the RACE II project Integrated Communications Management (ICM), addressing the technologies and methods required for the management of Integrated Broadband Communication Networks a discipline which is referred to as Telecommunications Management Network (TMN). The book is intended for telecommunications students, researchers, developers and operators in searc...

This paper presents a comprehensive model intended to analyse general quality in telecommunications services centred in end users’ perceived quality (PQoS). The proposed model allows us to estimate the quality experienced by end users, while offering detailed conclussions regarding the responsibility of the different agents involved in the service provision. We overview the structure of the mod...
