In the past, virtualisation, and with it the move toward the cloud, has had a strong influence on the ICT (Information Communication Technology) sector, and now seems set to revolutionise the telecommunications sector as well. The virtualisation into software artefacts of functions that would usually be deployed as hardware has come to be known as Network Function Virtualisation (NFV), and the European...
The Siyakhula Living Lab in the rural Eastern Cape province of South Africa has been in existence for over a decade now. In this time, several software artefacts have been developed by students and partners with the aim of providing contextually-relevant services to the rural community. However, reliance on different platforms and paradigms has meant that the deployment of such services would be difficult...
Development and implementation of appropriate e-services as well as revenue generation are key to deploying and sustaining ICT installations in poor areas in developing countries. The area of e-Health is a promising area for e-Services that are important to populations in poor areas and health service organisations that are already spending money on different health initiatives in these areas. This...
This paper discusses work to develop an e-Health system called HealthAware to assist health service organisations to carry out targeted health awareness campaigns in poor areas. The system comprises two components called the Dashboard and the Health Messenger, which are web-based, Java applications that run in a peer-to-peer fashion. The Dashboard is used to create, manage, and publish awareness campaigns...
As mobile network operators come to terms with the inevitability of falling revenues from traditional revenue streams, many have begun exploring alternative revenue models. A prominent approach has been to encourage the development of revenue-generating services by exposing network resources to developers through an application programming interface (API). The objective is to use common Internet Protocol...
The convergence of previously distinct networks into an All-IP network has resulted in an increase in the number and diversity of devices, channels and communication networks available to users. This has increased the number communication options available and is evidenced by the number of different communication devices owned and services subscribed to. How-ever, this has created complexities that...
The IP Multimedia Subsystem (IMS) is a telecommunication middleware platform with robust service features that enables the delivery of a wide range of services to mobile network subscribers. Network operators are encouraged to develop services from service building blocks in order to avoid redundancies by re-using existing functionality. In this environment, operators must be able to control the service...
Standards development organisations have long been in agreement that the most appropriate and cost effective way of developing services for the IP Multimedia Subsystem (IMS) is through the use — and re-use — of service capabilities, which are the building blocks for developing complex services. IMS specifications provide a theoretical framework for how service capabilities can be aggregated into large...
The IP Multimedia Subsystem (IMS) is a telecommunication middleware architecture that behaves as a docking station for a wide range of multimedia services. Several so-called killer applications have been envisioned for this platform such as multimedia group communications and location based services (LBS), but one of the most common business cases for IMS remains IPTV (Internet Protocol TV). Several...
