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...

The canonical IT security properties are geared towards infrastructure security. The task of an infrastructure security service is completed once data has been delivered to the application. When false data is submitted to the infrastructure, false data will be delivered securely. To secure an application, one thus may have to go beyond securing the infrastructure and in addition provide mechani...

The issue of trust and risk in outsourced relationships was extended beyond traditional outsourcing models with the introduction of Application Service Providers (ASPs). As ASPs evolve, Managed Security Service Providers (MSSPs) have emerged as external providers of security for firms facing increasing information assurance threats. This research-in-progress paper develops a conceptual model of...

All over the world we have been assisting to a significant increase of the telecommunication systems usage. People are faced day after day with strong marketing campaigns seeking their attention to new telecommunication products and services. Telecommunication companies struggle in a high competitive business arena. It seems that their efforts were well done, because customers are strongly adop...

The recent development of the telecommunication industries that form the " info structure " environment has enhanced economic activity through improved information technology (IT). IT could enlarge the volume of information flow, which accelerates productivity, but its impact on international trade has not been tested. The main objective of this thesis is to estimate the relationship between te...

In this work, diffusion processes in thermally connected cylindrical fibers with weakly guiding and circular cross-section, that is, telecommunication fibers, have been presented. There have been discussed diffusion distributions of the core dopant of fibers spliced at T ≈ 2000 °C. Gaussian approximations of the core dopant concentration distribution and refractive index in the connecting area ...

Every nation wants to achieve Universal Access of telecommunication services due to its importance to the economy and national life. Unfortunately in sub-Saharan Africa, telecommunication services are either scarce or non-existent in rural areas. However, previous telecommunication policies have enabled the provision of various network technologies in Africa. What type of policy is needed to pu...

In the past, telecommunication technologies did not present any particular problem for persons with visual disabilities. The telephones themselves were auditory in nature and could be operated by touch. As telecommunication begins to incorporate video and as telecommunication devices become more complex (including the incorporation of visual displays), new barriers are appearing. Fortunately, a...
