A framework for abstracting complexities in service delivery platforms

The telecommunication (telco) and Information Technology (IT) industries are converging into a single highly competitive market, where service diversity is the critical success factor. To provide diverse services, the telco network operator must evolve the traditional voice service centric network into a generic service centric network. An appropriate, but incomplete, architecture for this purpose is the Service Delivery Platform (SDP). The SDP represents an IT-based system that simplifies access to telco capabilities using services. SDP services offer technology independent interfaces to external entities. The SDP has vendor-specific interpretations that mix standards-based and proprietary interfaces to satisfy specific requirements. In addition, SDP architectural representations are technology-specific. To be widely adopted the SDP must provide standardised interfaces. This work contributes toward SDP standardisation by defining a technology independent and extendable architecture, called the SDP Framework. To define the framework we first describe telecom-IT convergence and a strategy to manage infrastructure integration. Second, we provide background on the SDP and its current limitations. Third, we treat the SDP as a complex system and determine a viewpoint methodology to define its framework. Fourth, we apply viewpoints by extracting concepts and abstractions from various standard-based telecom and IT technologies: the Intelligent Network (IN), Telecommunication Information Networking Architecture (TINA), Parlay, enhanced Telecommunications Operations Map (eTOM), Service Oriented Architecture (SOA) and Internet Protocol Multimedia Subsystem (IMS). Fifth, by extending the concepts and abstractions we define the SDP framework. The framework is based on a generic business model and reference model. The business model shows relationships between SDP, telco and external entities using business relationships points. The reference model extends the business model by formalising relationships as reference points. Reference points expand into interfaces exposed by services. Applications orchestrate service functions via their interfaces. Service and application distribution is abstracted by middleware that operates across business model domains. Services, interfaces, applications and middleware are managed in Generic Service Oriented Architectures (GSOA). Multiple layered GSOAs structure the SDP framework. Last, we implement the SDP framework using standard-based technologies with open service interfaces. The implementation proves framework concepts, promotes SDP standardisation and identifies research areas

A framework to provide charging for third party composite services

Includes synopsis.Includes bibliographical references (leaves 81-87).Over the past few years the trend in the telecommunications industry has been geared towards offering new and innovative services to end users. A decade ago network operators were content with offering simple services such as voice and text messaging. However, they began to notice that these services were generating lower revenues even while the number of subscribers increased. This was a direct result of the market saturation and network operators were forced to rapidly deploy services with minimum capital investment and while maximising revenue from service usage by end users. Network operators can achieve this by exposing the network to external content and service providers. They would create interfaces that would allow these 3rd party service and content providers to offer their applications and services to users. Composing and bundling of these services will essentially create new services for the user and achieve rapid deployment of enhanced services. The concept of offering a wide range of services that are coordinated in such a way that they deliver a unique experience has sparked interest and numerous research on Service Delivery Platforms (SDP). SDP‟s will enable network operators to be able to develop and offer a wide-variety service set. Given this interest on SDP standardisation bodies such as International Telecommunications Union – Telecommunications (ITU-T), Telecoms and Internet converged Servicers and Protocols for Advanced Networks) (TISPAN), 3rd Generations Partnership Project (3GPP) and Open Mobile Alliance (OMA) are leading efforts into standardising functions and protocols to enhance service delivery by network operators. Obtaining revenue from these services requires effective accounting of service usage and requires mechanisms for billing and charging of these services. The IP Multimedia subsystem(IMS) is a Next Generation Network (NGN) architecture that provides a platform for which multimedia services can be developed and deployed by network operators. The IMS provides network operators, both fixed or mobile, with a control layer that allows them to offer services that will enable them to remain key role players within the industry. Achieving this in an environment where the network operator interacts directly with the 3rd party service providers may become complicated

Les opérateurs sauront-ils survivre dans un monde en constante évolution? Considérations techniques conduisant à des scénarios de rupture

Le secteur des télécommunications passe par une phase délicate en raison de profondes mutations technologiques, principalement motivées par le développement de l'Internet. Elles ont un impact majeur sur l'industrie des télécommunications dans son ensemble et, par conséquent, sur les futurs déploiements des nouveaux réseaux, plateformes et services. L'évolution de l'Internet a un impact particulièrement fort sur les opérateurs des télécommunications (Telcos). En fait, l'industrie des télécommunications est à la veille de changements majeurs en raison de nombreux facteurs, comme par exemple la banalisation progressive de la connectivité, la domination dans le domaine des services de sociétés du web (Webcos), l'importance croissante de solutions à base de logiciels et la flexibilité qu'elles introduisent (par rapport au système statique des opérateurs télécoms). Cette thèse élabore, propose et compare les scénarios possibles basés sur des solutions et des approches qui sont technologiquement viables. Les scénarios identifiés couvrent un large éventail de possibilités: 1) Telco traditionnel; 2) Telco transporteur de Bits; 3) Telco facilitateur de Plateforme; 4) Telco fournisseur de services; 5) Disparition des Telco. Pour chaque scénario, une plateforme viable (selon le point de vue des opérateurs télécoms) est décrite avec ses avantages potentiels et le portefeuille de services qui pourraient être fournisThe telecommunications industry is going through a difficult phase because of profound technological changes, mainly originated by the development of the Internet. They have a major impact on the telecommunications industry as a whole and, consequently, the future deployment of new networks, platforms and services. The evolution of the Internet has a particularly strong impact on telecommunications operators (Telcos). In fact, the telecommunications industry is on the verge of major changes due to many factors, such as the gradual commoditization of connectivity, the dominance of web services companies (Webcos), the growing importance of software based solutions that introduce flexibility (compared to static system of telecom operators). This thesis develops, proposes and compares plausible future scenarios based on future solutions and approaches that will be technologically feasible and viable. Identified scenarios cover a wide range of possibilities: 1) Traditional Telco; 2) Telco as Bit Carrier; 3) Telco as Platform Provider; 4) Telco as Service Provider; 5) Telco Disappearance. For each scenario, a viable platform (from the point of view of telecom operators) is described highlighting the enabled service portfolio and its potential benefitsEVRY-INT (912282302) / SudocSudocFranceF

Scalable IoT platforms

In today’s world the internet is connecting not only people but things. The computing concept of the ”Internet of Things (IoT)”describes the idea to connect everyday physical objects to the internet. IoT platforms provide the backbone for applications in areas like Smart Home, Connected Vehicles and Industrial IoT. In this thesis, we explore the question of the best IoT platform with a focus on reliability, scalability and heterogeneity. To answer this question, we search the market for IoT platforms, prototypes and proposals, examine them based on our comparison model and rate the platforms in a five star system. The criteria for the parts of the comparison model include replication, availability, authentication and authorization, encryption, security incidents and audits, development and market longevity for reliability, hosting, Edge and Fog Computing, limits of the infrastructure and network and load balancing for scalability, device restrictions, messaging and device protocols, programming languages and flexibility for heterogeneity as well as usability, pricing models and unique selling points. We discover that most criteria do not differ in the used technologies or algorithms, but if they is implemented or not. Despite there is a low level of standardization, most criteria is implemented in a similar way across the platforms. The overall best rated platform is Microsoft Azure IoT Hub with 4.25 out of 5.0 stars, followed by IBM Watson IoT (3.88 stars). The prototype platform OceanConnect by Huawei shows promising results as well (3.0 stars)

Complexity aided design: The FuturICT technological innovation paradigm

"In the next century, planet earth will don an electronic skin. It will use the Internet as a scaffold to support and transmit its sensations. This skin is already being stitched together. It consists of millions of embedded electronic measuring devices: thermostats, pressure gauges, pollution detectors, cameras, microphones, glucose sensors, EKGs, electroencephalographs. These will probe and monitor cities and endangered species, the atmosphere, our ships, highways and fleets of trucks, our conversations, our bodies-even our dreams ....What will the earth's new skin permit us to feel? How will we use its surges of sensation? For several years-maybe for a decade-there will be no central nervous system to manage this vast signaling network. Certainly there will be no central intelligence...some qualities of self-awareness will emerge once the Net is sensually enhanced. Sensuality is only one force pushing the Net toward intelligence”. These statements are quoted by an interview by Cherry Murray, Dean of the Harvard School of Engineering and Applied Sciences and Professor of Physics. It is interesting to outline the timeliness and highly predicting power of these statements. In particular, we would like to point to the relevance of the question "What will the earth's new skin permit us to feel?” to the work we are going to discuss in this paper. There are many additional compelling questions, as for example: "How can the electronic earth's skin be made more resilient?”; "How can the earth's electronic skin be improved to better satisfy the need of our society?”;"What can the science of complex systems contribute to this endeavour?” Graphical abstrac

Cooperating broadcast and cellular conditional access system for digital television

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.The lack of interoperability between Pay‐TV service providers and a horizontally integrated business transaction model have compromised the competition in the Pay‐TV market. In addition, the lack of interactivity with customers has resulted in high churn rate and improper security measures have contributed into considerable business loss. These issues are the main cause of high operational costs and subscription fees in the Pay‐TV systems. This paper presents a novel end‐to‐end system architecture for Pay‐TV systems cooperating mobile and broadcasting technologies. It provides a cost‐effective, scalable, dynamic and secure access control mechanism supporting converged services and new business opportunities in Pay‐TV systems. It enhances interactivity, security and potentially reduces customer attrition and operational cost. In this platform, service providers can effectively interact with their customers, personalise their services and adopt appropriate security measures. It breaks up the rigid relationship between a viewer and set‐top box as imposed by traditional conditional access systems, thus, a viewer can fully enjoy his entitlements via an arbitrary set‐top box. Having thoroughly considered state‐of‐the‐art technologies currently being used across the world, the thesis highlights novel use cases and presents the full design and implementation aspects of the system. The design section is enriched by providing possible security structures supported thereby. A business collaboration structure is proposed, followed by a reference model for implementing the system. Finally, the security architectures are analysed to propose the best architecture on the basis of security, complexity and set‐top box production cost criteria

Concept of a distribution and infrastructure model for mobile applications development across multiple mobile platforms

Der Markt fuer mobile Applikationen ist in den letzten Jahre drastisch gewachsen, vorallem durch die staendige steigende Zahl and Mobiltelefonen. Gruende fuer den raschen Anstieg sind unter anderem die steigende Anzahl an Applikationsportalen von Endgeraeteherstellern sowie Telekomunternehmen. Durch die Vielzahl an unterschiedlichen Endgeraeten mit konkurrierenden Betriebssystemen, Entwicklungsplatformen, physische Charaktersistika sowie Netzwerk Infrastrukturen ist ein in sich komplexes Oekosystem entstanden. Durch die Unterschiede der Systeme ist vorallem auf Seiten der Applikationsentwicker ein hoher Grad an Unsicherheit in Bezug auf die Entwicklungsstrategie entstanden was die Technologie und vorallem auch die Nachfrage betrifft. Das Ziel dieser Arbeit ist es ein “aggregiertes” Modell fuer die Distribution von Applikationen ueber mehrere Platformen zu finden. Im ersten Schritt wird die Analyse der existierenden Literatur in der Fachpresse, Internetquellen und Experteninterviews zum Thema Distributions- und Infrastrukturlandschaft in Form eines „Top-Down“ Ansatzes durchgefuehrt um eine Vergleichsbasis aufzubauen und eine Bewertung durchfuehren zu koennen. Im Folgenden wird die Modellierung der analysierten Geschaeftsprozesse mit dem ADONIS® Business Process Management Toolkit durchgefuehrt sowie fuer die Erstellung der Infrastrukturmodelle ADOit® IT Architecture- & Service Management Toolkit verwendet. Die daraus resultierenden Ergebnisse werden analysiert und gegen die „ideal“ Charakteristika verglichen und ein aggregiertes Modell erstellt. Im Anschluss wird der Ansatz eines aggregierten Models in Form der Meta Platform WAC getestet indem deren Entwicklungsumgebung fuer die Erstellung einer Beispielsapplikation verwendet und die Kompatibilitaet auf verschiedenen Platformen getestet wird.The mobile application market continues to grow drastically due to the explosion in the sales of mobile device. One of the drivers behind that increase is the development and penetration of application stores provided by different stakeholders in the mobile space especially handset manufacturers, operating system developers and network operators. Therefore handsets nowadays contain competing operating systems, development platforms and physical characteristics. This diversity leads to a large degree of uncertainty in the mobile space on a strategic, technological, and demand level for mobile application developers. Currently developers need to decide which platform to develop and distribute for. Decision factors include among others the target market, compatibility issue, development time, hardware requirements and scalability. This work provides an overview of the existing mobile application and app store market, investigating in business models, processes and infrastructures to develop and distribute mobile applications across multiple platforms. As the goal is to find an aggregated model for the distribution of cross-platform applications I will start with a top-down approach to identify the existing distribution and infrastructure landscape, therefore I will conduct a research of the literature, internet i.e. Application store developer sites, specialized press and expert talks. The modelling of the business processes will be done with ADONIS® Business Process Management Toolkit and the modelling of infrastructures with ADOit® IT Architecture- & Service Management Toolkit. The final part of the thesis describes the development of a sample application using the WAC environment and the compatibility of on different platforms will be tested
