The universal mobile telecommunication system (UMTS) (3rd Generation Partnership Project [3GPP] TS 23.002, 2002) is a realization of third generation (3G) networks, which intend to establish a single integrated system that supports a wide spectrum of operating environments. Users have seamless access to a wide range of new telecommunication services, such as high data rate transmission for high...

This paper presents our approach integrating a high level of intelligence within telecommunication networks. Artificial intelligence has proved its efficiency in resolving complex issues in different fields like air traffic control, robotics, and medical diagnosis. However its usage in telecommunication networks is still very moderated. The main objectives of our framework is to encourage the d...

The paper deals with the test signal selection to be adopted for the Voice Quality Measurement (VQM) in telecommunication networks. It is proposed to use the optimized multisine as test signal in place of both the natural and the artificial voices, suggested by the ITU-T recommendations. The effectiveness of the optimized multisine to the VQM is investigated by using four algorithms: (i) Percep...

Vaccination and outbreak monitoring are essential tools for preventing and minimizing outbreaks of infectious diseases1–8. Targeted strategies, where the individuals most important for monitoring or preventing outbreaks are selected for intervention, offer a possibility to significantly improve these measures5, 7, 9. Although targeted strategies carry a strong potential, identifying optimal tar...

New telecommunication services and mobility networks have introduced databases in telecommunication networks. Compared with traditional use of databases, telecom databases must fulfill very tough requirements on response time, throughput, and availability. ClustRa is a telecom database prototype developed to run on standard workstations interconnected by an ATM switch. To meet the throughput an...

Understanding the individual behavior has shown to be of paramount importance to the triumph of the telecommunication operators to retain customers, enhance their purchasing capacity, and predict the churn rate. Different behavior patterns can be observed for different groups of users. Hence, there is an interesting problem posted in telecommunication network that how to define the users’ role ...

The rapid growth in the telecommunication market increases the performance requirements on applications supporting telecommunication networks. Many of these applications are based on commercial Relation DataBase Management Systems (RDBMS), a component which tends to become a bottleneck. Therefore, it is important to fully use the capacity of the database. A database server can usually not be fu...

Following the commercial deployment and worldwide success of 2 generation mobile telecommunication systems, standardization bodies, industry partners and regulatory fora from around the globe joined forces in producing the standards for 3 generation mobile telecommunication systems. In parallel, the academic research community has been gradually shifting its focus in defining the scope of 4 gen...

This paper presents the Cross Infrastructure Attack Attribution Toolkit (CAT), which is a utility to analyze the vulnerability of 3G networks using telecommunication specifications. CAT analyzes vulnerabilities by generating attack graphs, which show the global view of the network in the event of an attack. The uniqueness of CAT is as follows: (1) usage of telecommunication specification writte...

Fuzzy inference method based approach to the forming of modular intellectual system of assessment the quality of communication services is proposed. Developed under this approach the basic fuzzy estimation model takes into account the recommendations of the International Telecommunication Union in respect of the operation of packet switching networks based on IPprotocol. To implement the main f...
