We describe our unifying architecture for multipoint-to-multipoint communications in ATM networks which meets the diverse requirement of group communications and permit a large degree of control on the multicast group. With an integrated use of a name space, the scheme allows scalable extension to large scale wide area multicast communications. We also enable exible control on routeing architec...

Public alerting is a major challenge in world where risks and communication modes are constantly evolving. Since few years, new massive tools geolocating the population real time (Cell Broadcast or Location-Based SMS) have been deployed at national level several countries. However, this evolution does not always reach with local needs. Decision-makers can use wide multiplicity of induce vulnera...

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...

Electromagnetic (EM) shielding has become an essential element in the modern world alongside increased use of electronic products and telecommunication equipment. We are surrounded by electromagnetic fields that have inevitably formidable our lives. It is possible to absorb EM waves adding materials. Researches focused addition different additives into cement based mixture increase shielding. T...

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 ...
