- Description: 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 commu-nication options available and is evidenced by the number of different communication devices owned and services subscribed to. How-ever, this has created complexities that call for proper methods to manage these diverse and in-compatible communication options. The objective of Unified Communication (UC) is to seamlessly integrate the dispar-ate communication channels into a device independent plat-form that can easily be managed by users. Due its focus on a largely urban and highly connected market, UC has not benefited marginalized communities. This paper discusses the design and implementation of Unicorn, a UC solution for a middleware software platform called Teleweaver which was designed to support the development of services for marginalized communities. The solution integrates services from a telecommunication container called Mobicents. It seamlessly amalgamates voice, data and video onto one device independent unified platform easily accessible by users.

- Description: Rural schools have a pressing need for ICT and Internet services, for them-selves and the surrounding communities. Educators can play a crucial role of fulfilling this need. But how ready are schools, educators and communi-ties to engage with ICT and use it for their empowerment? This paper re-ports the findings of an e-readiness assessment and promotion drive by re-searchers from the Siyakhula Living Lab in parts of the Mbashe Municipali-ty, in South Africa. The Siyakhula Living Lab is a multi-disciplinary, multi-year initiative to foster grassroots innovation in marginalized communities with the aim of improving their lives and economies. The drive was con-ducted to support the expansion of the network of Digital Access Nodes, ie ICT points-of-presence of the Living Lab in the community: this network rep-resents the structural backbone on which all other activities rest. The as-sessment shows that, while the practical difficulties are many, the communi-ties are very eager to engage with ICT and understand fairly well the con-nection between ICT availability and the possibility of improvement in their life conditions.

- Description: Underdevelopment and poverty represent key challenges faced by the modern world, which have attracted the attention of NGOs, civil society, government and multinationals. Various undertakings including the United Nations Millennium Development Goals articulation and the World Summit on Information Society highlight the global commitment towards addressing these problems. The solutions to these problems should be derived out of well-structured innovation systems that take into consideration the grassroot context and concerns. A number of in-novation models have been formulated and utilized effectively in differ-ent industries, and some of these have equally been used effectively in community development contexts. This paper elaborates on the Living Lab methodology and its application in ICT4D contexts, highlighting the effectiveness of this model towards integrating end-users within their problem solving effort. This is discussed through the backdrop of the Siyakhula Living Lab, an ICT4D intervention. The embedding environ-ment for this model, which enables key synergies with other stakehold-ers, is also discussed.

- Description: 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 environ-ment, operators must be able to control the service execution chain in order to prevent undesirable interactions from occurring between indi-vidual building blocks. It is also in their interests to provide subscribers with personalisation options so that they can modify service composi-tions and define their own preferences for how they would like their ser-vices to behave during live sessions. This paper describes a solution for these challenges that involves the storage of service information in an XDMS and allows operator staff and subscribers to manage this in-formation using the XCAP protocol. The ETSI-defined XCAP applica-tion usage named simservs was chosen to demonstrate an application usage that can be used to create service compositions in XML format. A prototype is described that uses components of the open source Mo-bicents project to verify the suitability of the design. This work is part of a larger effort aimed at modeling interaction management in the IMS through the use of a service broker that is part of an extended IMS ser-vice layer (EISL). The service broker's functional and structural architec-ture have not yet been standardised.

- Description: In South Africa, English plays a dominant role compared to African lan-guages in empowering domain. Better access to Education through the use of African languages is an object of heated debate. This paper shows that an intervention involving the use of an African language in the domain of ICT Education can change the attitudes of Black universi-ty students. The methodology used included a survey with preliminary and follow-up questionnaires and interviews and an intervention involv-ing the use of localised software and of an on-line glossary of computer terms translated, explained and exemplified in an African language (isiXhosa). This experience increased the support for the use of African languages as additional LoLT, even in the English-dominated field of study of Computer Science. This is an initial step towards promoting linguistic equality between English and African languages and social equality between their speakers.

- Description: ICTs, driven by the convergence of computers, telecommunications and traditional media, are crucial for the knowledge-based economy of the future. The rapid technological changes have resulted in different ideas being suggested for the expected ICT applications. As a result, different e-Service applications have being developed as a way to fos-ter ICT developments. However, ICT applications deployed at the mo-ment may not be able to sustain the rural communities in maybe 10 years or more to come. The paper considers the past, analyzes the present and conduct surveys to gain insight into the future. Based on all of this information, the research tries to provide an ICT road map for what is to come. What kind of applications can we develop now to cater for the technological changes, so that the ICT applications developed today would still be compatible with those developed in years to come? The Siyakhula Living Lab (SLL) is used as the case study in this paper and some interviews and literature review are done to get different ide-as on the future of ICTs.

- Description: With developments in the Internet and Web-based technologies, dis-tinctions between traditional markets and the global electronic market-place-such as business capital size, are gradually being narrowed down. It is recognized that in the Information Age, e-Commerce is a powerful tool for economic growth of developing countries. While there are indications of e-Commerce patronage among large firms in devel-oping countries, there seems to be little and negligible use of the Inter-net for commerce among small and medium sized firms. However, many of these e-Commerce projects in marginalized areas fail as a re-sult of lack of the required resources to support ICTs. Different ways have been suggested for marketing products online and to create cus-tomer loyalty. This paper discusses a marketing and customer loyalty strategy through a real-time interactive negotiation application, aimed at improving the existing e-Commerce platform. The e-Commerce platform has been deployed as part of the Siyakhula Living Lab ICTD project which is undertaken for the Dwesa community in the Eastern Cape province of South Africa.

- Description: 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 service appli-cations. However, there is little evidence that mainstream IMS service development is capability-based, and many services are still designed in a monolithic way, with no re-use of existing functionality. Telecom-munication networks are well positioned to stimulate the Internet ser-vices market by exposing these service enablers to third parties. In this paper, we marry the two issues by defining an extended IMS service layer (EISL) that provides a service broker that is the central agent in both service interaction management and the execution of external re-quests from third parties. A prototypical implementation of the service broker is described that was developed using a converged SIP servlet container, and a discussion is also provided that details how third party developers could use HTTP APIs to interact with a service broker in or-der to gain access to network capabilities.

- Description: As the amount of commercial transactions carried out on t he Internet in-creases, the interest to partially or totally automate the negotiation of the terms of these transactions has rapidly become an interesting research topic. Several e-marketing strategies through various online websites have been developed. In rural communities e-services applications such as e-commerce, ehealth, e-judiciary and e-government have been devel-oped. However, most of these applications are failing to fully benefit the people in the societies because they are no modifications which are done to the applications as technology changes. This paper discusses the de-velopment of an intelligent negotiation module to enhance an e-commerce platform. The paper explains a negotiation application that has been developed and plugged to any existing e-Commerce shopping por-tal for the Dwesa Community in the Eastern cape province of South Africa and proposes an architecture for all other e-Services. This project ex-plained is undertaken within the Siyakhula Living Lab.

- Description: Several open source SIP/IMS Clients are currently in use in the Rhodes University Convergence Research Group. However, there is no single Client that provides researchers with all the required functionality need-ed to test the applications they have developed. Integrating advanced features into a single Client can help to speed up testing as well as pro-vide a variety of innovative communication services. In this paper we present an overview of two popular SIP/IMS Clients currently in use. We also discuss the features and design architecture of a Client called JAIN SIP Applet Phone (JSAP) which will be used as a basis for the development of a new IMS compliant Client. We then analyse what functionality JSAP lacks and propose features that need to be imple-mented.

We also discuss the features and design architecture of a Client called JAIN SIP Applet Phone (JSAP) which will be used as a basis for the development of a new IMS compliant Client. We then analyse what functionality JSAP lacks and propose features that need to be imple-mented.

- Description: There has been much attention recently on the use of virtual class-rooms to support distance learning. However, the required real-time and high-rate transfers for multimedia contents such as video and audio that comprise most off-the-shelf virtual classrooms make them infeasible for developing countries where bandwidth is typically more restricted. This paper describes the findings of an ongoing investigation to develop a low bandwidth virtual classroom that can provide the necessary func-tionality to deliver courses to distant students. By combining Google Docs and Skype, we realised a low bandwidth virtual classroom alterna-tive that could provide adequate functionality within our teaching con-text.

- Description: Information and Communication Technology (ICT) has made it possible to explore novel and innovative mechanisms to leap-frog socio-economic development in rural and marginalized communities. An ICT for development intervention called Siyakhula Living Lab (SLL) has been underway in Dwesa, a rural community in the Eastern Cape Prov-ince, for the past four years. The living lab methodology, which enables user-driven innovation within a multi-stakeholder relationship of aca-demia, user communities, government and private industry, has facili-tated greater integration of the Dwesa community into the digital ecolo-gy and subsequently the knowledge society. This paper introduces the SLL intervention, discusses the SLL's supporting technical infrastruc-ture and the interventions that are undertaken towards long-term sus-tainability of the project. The developed eServices are also discussed, with a view to highlighting the key characteristics that contribute to in-creased context-sensitivity, ownership, and buy-in from the community.

- Description: In this article we explore the possible contribution of the Web in promot-ing the use and status of African languages. Participation in sharing and producing knowledge through the Web can play a key role in the eco-nomic, social and educational development of Africa. While physical ac-cess to information is hampered by lack of infrastructure and connectivi-ty, epistemological access is hampered by the use of English. Re-sources in African languages are available. Until the amount of Web content and the number of users reach critical mass, these resources play a symbolic rather than an instrumental role in promoting African lan-guages. The use of electronic resources available on the Web could contribute to cutting the printing and transport cost of paper material, es-pecially in multilingual settings where many languages would have to be represented. Another practical way in which the Web can promote the development of African languages is to promote communication among their speakers. This is already showing its potential by allowing experts from various disciplines to work collaboratively on the development of new indigenous terminology through mailing lists and chat rooms. On a larger scale, the Web can play a unifying function among speakers of different varieties of the same African language.

- Description: The IP Multimedia Subsystem (IMS) is a telecommunication middleware architecture that behaves as a docking station for a wide range of mul-timedia services. Several so-called killer applications have been envi-sioned 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 IMS stand-ards development bodies and non-IMS players have contributed knowledge to the topic of IPTV, and the mechanisms needed to support various IPTV services are well understood. In addition, there are exam-ples of researchers who have implemented IPTV services in their net-work testbeds. However, many of them do not make use of the full power of the specifications which describe the mechanisms of service discovery and service selection. These processes define support for customer device configuration, service personalisation and service se-lection in a multi-service provider ecosystem. This position paper pro-poses solutions to some of the open questions in this area and pro-vides an architecture for a testbed that properly supports service dis-covery and selection. An initial implementation addressing the topic of auto-configuration of IMS terminals for service discovery is also pre-sented.

- Description: The IP Multimedia Subsystem is a telecommunications framework with a standard architecture for the provision of services. While the services themselves have not been standardised, standards do exist for basic technologies that can be re-used and aggregated in order to construct more complex services. These elements are called service capabilities by the 3GPP and service enablers by the OMA, both of which are repu-table standards bodies in this area. In order to provide re-usability, there is a need to manage access to the service capabilities. Also, in order to build complex services, there is a further need to be able to manage and coordinate the interactions that occur between service capabilities. The 3GPP and the OMA have separately defined network entities that are responsible for handling aspects of these requirements, and are known as a service capability interaction manager (SCIM) and a policy enforcer respectively. However, the internal structure of the SCIM and the policy enforcer have not been standardised by the relevant bodies. In addition, as the SCIM and the policy enforcer have been defined through complementary yet separate processes, there is an opportunity to unify efforts from both bodies. This paper builds on work and stand-ards defined by the bodies, and proposes the design of an interaction manager with features borrowed from both the SCIM and the policy en-forcer. To help validate the design, we have identified a platform known as JAIN SLEE which we believe conforms to the model proposed, and we discuss how JAIN SLEE can be used to implement our ideas.

- Description: In this article we argue for the use of African languages as Languages of Learning and Teaching (LoLT) for native speakers of such language in South Africa. We believe that both public and academic debate is in-fluenced by a set of ‘language myths’: 1) only one language should be used; 2) the earlier one starts using English as LoLT, the better; 3) us-ing English as LoLT improves English proficiency. These myths be seen as a direct manifestation of Western hegemony, and English-functional arguments are often the terms of reference. We will try a dif-ferent approach by highlighting the advantages of using an African lan-guage (ie isiXhosa) as LoLT and, whenever possible, we will try to put English on the ‘defence stand’. The purpose of this paper is not to ad-vocate the substitution of English with an African language. We believe that bilingual education is the appropriate choice for South Africa, but in order to achieve full equality between English and the African lan-guages in education, arguments in support of the latter must be put forward proactively. With our paper, we hope to contribute to this new perspective.

- Description: A growing proliferation of ICT4D interventions has necessitated the ex-ploration of innovative solutions for the provisioning of eServices in ru-ral, marginalized communities. The challenges currently faced in these interventions include: situating the developed applications within the cultural and ethnographic context of the target communities, integrating greater levels of granularity and flexibility within the applications for in-creased context sensitivity, handling the intermittence and instability of supporting infrastructural services. These are the challenges that we address in the context of ICT4D intervention undertaken in a rural community in the Eastern Cape province of South Africa. We explore the design and implementation of a Multi-Agent System (MAS) for this community as a platform for provisioning of context-sensitive eServ-ices, and highlight some observations with regards to the applicability and adequacy of the solution.

- Description: Traditionally digital marginalization and exclusion were understood to be a factor of connectivity to the Internet, affordability of the technology, and the capability of the communities to utilize the technology. ICT for development (ICT4D) interventions have been undertaken that address these specific factors of marginalization, however, it remains that com-munities are still excluded from the global knowledge society. In this paper we argue that key factors towards reaching greater inclusion and participation of the digitally marginalized communities, are the knowledge-centricity and context-sensitivity of the undertaken interven-tions. The solutions developed, and the services deployed, must intrin-sically encapsulate the local knowledge within the community of de-ployment. Based on this premise we have developed an architectural framework, named PIASK, that formalizes the contextualization of the developed applications within the socio-technical environment and po-sitions them within the local knowledge system of the community. We highlight the components of this architecture and discuss its implemen-tation through a knowledge platform for a community in South Africa.
