FOREWORD The ITU-T (Telecommunication Standardization Sector) is a permanent organ of the International Telecommunication Union (ITU). The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets e...

Conventional manual approach to DSP code generation usually takes the major manpower allocation in telecommunication design. A retargetable DSP code generation methodology based on SUIF is therefore proposed to address this problem in Fujitsu telecommunication design environment. This automatic code generation ow is brieey reported in this paper. Some essential code generation issues speciic to...

User requirements for telecommunication systems are difficult to understand because they are obscured by a long history of ad hoc feature development and technological limitations. The presence of a viable modular architecture for telecommunication features gives us a fresh start. Working within this framework, we can discover desirable properties that ought to be requirements for all telecommu...

As long as there have been databases there has been a large interest in measuring their performance. Therefore, several different benchmarks have been proposed. However, previous proposals do not consider timely response and other telecommunication application requirements. This paper shortly reviews telecommunication requirements and previous work on real-time databases. These requirements are...

The restructuring of telecommunication in Central and Eastern Europe occurs at a time when the classical structures of telecommunication are falling apart worldwide. Coming from the socialist system in which telecommunication did not exist as an independent economic activity, the Eastern European countries have created specific “post-socialist“ modes of reform, often outdoing Western countries ...

Telecommunication companies generate a tremendous amount of data. These data include call detail data, which describes the calls that traverse the telecommunication networks, network data, which describes the state of the hardware and software components in the network, and customer data, which describes the telecommunication customers. This chapter describes how data mining can be used to unco...

Fixed–mobile convergence (FMC) is a radical innovation for telecommunication companies because it requires them to move into unknown territories that are beyond traditional business lines and underlying technologies. In the meantime, understanding what types of telecommunication companies are better at doing business through the early adoption of FMC has become increasingly important in the con...

We present an overview of our approach to managing security as a dimension of Quality of Service. Relative to traditional QoS attributes (e.g., jitter, deadline, latency) security has been handled rather statically and indirectly. We have developed a theory of Quality of Security Service and a related security-costing framework that supports extension of QoSS functionality to embrace existing a...
