A telecommunication system like an ISDN network comprises a great variety of software components. It includes software for switches, the terminal equipment (like a simple telephone) but also for the management of resources and the provision of high level services like time dependent call forwarding. Software for telecommunication systems like other software must be fast, robust and easy to main...

The mobile telecommunication industry is becoming one of the most important industries in the world. In the spectrum of wireless communication technologies, digital cellular telecommunication using the Global System of Mobile Communication (GSM) standard has enjoyed the fastest growth rate. This paper attempts to examine GSM driving factors on a national level. For this purposes, it uses system...

In this paper, we give an overview of using High Altitude Platforms (HAPs) for providing wireless telecommunication and broadband communication services. Comparisons of HAPs, satellite and terrestrial systems are shown to illustrate unique characteristics of the system. Three architectures for HAP systems are discussed in terms of cooperation with terrestrial and satellite systems. Telecommunic...

Telecommunication networks process verylarge numbers of events in real time. In this environment, database applications demand both high throughput (at reasonable costs), and predictable, millisecond response times. Conventional disk-based database systems were not designed to meet such requirements. This paper sketches some real-time telecommunications applications, describes their database re...
