Future telecommunication services will extensively exploit database technology. The persistent and temporal information needed in operations and management of the telecommunication networks and services will be in databases. The current IN Recommendations of ITU-T (Q.1200 Series) imply that real-time transaction processing capabilities should be provided. We present an experimental real-time ob...

This paper proposes a novel forecasting method which is applicable for new services, where little historical data has been recorded. The method uses instead estimators based on economical, demographic and traffic data. The method is, compared to traditional forecasting procedures that are built upon a solid historical record of data, clearly found to be weaker numerically. However, for novel se...

We analyzed the effect of the level of low asset specificity IT outsourcing on firm-level financial performance. We used transaction cost economics (TCE) as the theoretical basis to explain the effect of the level of network and telecommunication services outsourced on financial performance. An analysis of 1444 Integrated Healthcare Delivery Systems revealed that higher levels of network and te...

Global telecommunication networks and services are among the enterprises having the highest volumes of real-time data. A voice network may complete more than 250 million calls per day. Each is described by one or more events, yielding a total of tens of gigabytes of data daily. Wireless, Asynchronous Transfer Mode (ATM), frame relay, Internet Protocol (IP) networks and higher-level services on ...

The ability of modern telecommunication services to adapt more and more aspects of their service to users’ needs is becoming of crucial importance. This is due to the fact that these services are getting increasingly complex and are also entering the user’s extremely sensitive social domain. Approaches developed to mitigate these issues rely on user data acquired in a non-intrusive way. Social ...

Even though there are many testing methods for telecommunication systems very little has been said about test execution in distributed environments. This paper addresses this problem and proposes the implementation and test of telecommunication services on a CORBA-like platform. We present a test architecture for distributed systems and describe system components and test execution phases. An i...

Future broadband wireless services will involve a range of different technologies, all with varying characteristics. These differences can influence significantly how a service is defined and deployed as well as how it is commercially offered to customers. Key technologies and services that will influence and shape the future broadband telecommunication market include WiFi services based on IEE...

Telecommunication networks are growing very fast. The user’s needs, in regards to new services and applications that have a higher bandwidth requirement, are becoming bigger every day. A telecommunication network requires early design, planning, maintenance, continuous development and updating, as demand increases. In that respect we are forced to incessantly evaluate the telecommunication netw...
