    Optimized IP-CANs to support best charged IMS scenarios

    conference paper Published in Personal, Indoor and Mobile Radio Communications, 2009 IEEE 20th International Symposium by IEEE.The pricing and charging mechanisms used in Next Generation Network (NGN) deployments will influence the profitability of network operators. NGNs present an opportunity for the success of service delivery platforms designed for IP multimedia communications, like the IP Multimedia Subsystem (IMS). Moreover, they present a platform for the delivery of a multitude of applications and services to users with different expectations and budgets. Although usage-based charging schemes are more meaningful, some recent successful Internet-based applications and services have attracted widespread usage due to enforcement of flat-rate pricing. The choice of a pricing scheme often has a one-to-one relation to the access network technology and the quality of service guarantee. Flat-rate pricing may easily be associated with best effort transport. This implies that some users opt for services without QoS guarantee when favoured by the pricing methodology. This paper explores scenarios where services with different QoS requirements available to users with varying pricing preferences can be provided over a set of IP connection access networks (IP-CANs) of the IMS.We explore the use of different pricing schemes for different IP-CANs of the IMS. We perform testbed evaluations and present results depicting the income patterns of networks enforcing different pricing and charging schemes for VoIP and IPTV services. Moreover, we emphasize the use of simplified pricing schemes on communication networks.The pricing and charging mechanisms used in Next Generation Network (NGN) deployments will influence the profitability of network operators.

    Semi-automated creation of converged iTV services: From macromedia director simulations to services ready for broadcast

    While sound and video may capture viewers’ attention, interaction can captivate them. This has not been available prior to the advent of Digital Television. In fact, what lies at the heart of the Digital Television revolution is this new type of interactive content, offered in the form of interactive Television (iTV) services. On top of that, the new world of converged networks has created a demand for a new type of converged services on a range of mobile terminals (Tablet PCs, PDAs and mobile phones). This paper aims at presenting a new approach to service creation that allows for the semi-automatic translation of simulations and rapid prototypes created in the accessible desktop multimedia authoring package Macromedia Director into services ready for broadcast. This is achieved by a series of tools that de-skill and speed-up the process of creating digital TV user interfaces (UI) and applications for mobile terminals. The benefits of rapid prototyping are essential for the production of these new types of services, and are therefore discussed in the first section of this paper. In the following sections, an overview of the operation of content, service, creation and management sub-systems is presented, which illustrates why these tools compose an important and integral part of a system responsible of creating, delivering and managing converged broadcast and telecommunications services. The next section examines a number of metadata languages candidates for describing the iTV services user interface and the schema language adopted in this project. A detailed description of the operation of the two tools is provided to offer an insight of how they can be used to de-skill and speed-up the process of creating digital TV user interfaces and applications for mobile terminals. Finally, representative broadcast oriented and telecommunication oriented converged service components are also introduced, demonstrating how these tools have been used to generate different types of services

    Business Case and Technology Analysis for 5G Low Latency Applications

    Get PDF
    A large number of new consumer and industrial applications are likely to change the classic operator's business models and provide a wide range of new markets to enter. This article analyses the most relevant 5G use cases that require ultra-low latency, from both technical and business perspectives. Low latency services pose challenging requirements to the network, and to fulfill them operators need to invest in costly changes in their network. In this sense, it is not clear whether such investments are going to be amortized with these new business models. In light of this, specific applications and requirements are described and the potential market benefits for operators are analysed. Conclusions show that operators have clear opportunities to add value and position themselves strongly with the increasing number of services to be provided by 5G.Comment: 18 pages, 5 figure
