The IP multimedia subsystem (IMS) is the main component of 3G networks. It aims at the seamless provisioning of multimedia services to end-users. This paper presents a case study on multiparty multimedia game development in IMS. It first reviews the APIs and tools available for multiparty multimedia conferencing applications (e.g. games) development in IMS. It then presents the semantics of the game...
Current service platforms or frameworks, e.g., cloud solutions, do not take the infrastructure, necessary for the execution of the service, sufficiently into consideration. They take resources like network connectivity for granted and do not provide an integrated networking approach considering quality of service (QoS) or other real-time aspects of the message exchange between possibly thousands of...
The GPS (Global Positioning System) is Global Navigation Satellite system used for navigation purposes. Now days, GPS enables the vehicle drivers to check the real time position of there vehicle onto a preloaded map with features like, mapping of way to a location etc. The RDS (Radio Data System) is the best and cheapest way of broadcasting digital information over Frequency Modulation (FM). These...
We have introduced a new VPN system that uses SIP to enable NGN users to easily create IPsec tunnels. In this paper, to expand business opportunities, we propose a new business model for the system. We will discuss that a service model that has evolved over telephone-networks can be applied to the system.
Current IMS development follows the path of improving the IMS clients and client frameworks. This paper points out the shortcomings of this path for deployment in a mobile-fixed convergent multi-access IMS environment. Instead of continuing the development on IMS client frameworks, an alternative path forward using IMS client widgets is proposed as a novel concept. It involves a thin-client solution...
The paper look into the use of a personal smart phone as a main controlling entity for personal communication (using IM, audio or video) in an office environment. The service PPCom (personal pervasive communication) is a kind of `Follow-Me' service. This paper presents the architecture and the design. The architecture is based on a clear separation of `call' and `connection' according to NGN. The...
The usage of social networking sites has increased considerably over the past few years. Nowadays, participating in online communities has become an everyday activity in the lives of millions, world-wide. Also, in enterprises, employees are now faced with a diverse set of online tools (e.g. wikis, blogs) with the purpose of enhancing collaboration and productivity, while surmounting traditional communication...
A profound impact of the Web2.0 lies in its power to transform skilled users into service providers, resulting in more complex value networks. As recently traditional ??operated?? network infrastructure is complemented with huge amounts of connected smart objects (the Internet-of-Things), the same mass creativity can be made applicable to smart, context-enabled services with real-world interactivity,...
Started with some definitions of Telecom 2.0 and a brief discussion of business models, this paper then asked if there still are opportunities for start-ups in the Telecom 2.0 world. The authors proposed a user-centric approach for a telecom start-up. The business model is centred on multiple identity support, holistic Internet customer care, and safe online transactions. Since it is part of the poster...
Supporting Quality of Service (QoS) in a core transport is an important feature of a next generation network. This feature not only enables real-time communication services such as Voice over IP (VoIP) and video telephony, but also helps create new applications. However, access gateway such as Packet Data Gateway (PDG) in IMS WLAN Interworking, located at the edge of an IMS core network, must inspect...
The research presented in this paper is focused on the technology and the business model provided for the modernization of the incumbent wireline carrier's infrastructure, especially on the evolutionary PSTN emulation approach. With the deployment of the described PSTN Emulation approach, the carrier can take the opportunity to reuse its existing access network, replace obsolete technology and bring...
The present paper describes practical experience gained with IMS based fixed mobile convergence (FMC) network deployment at TDC Denmark. The paper also takes a look into the near future, showing trend in technology. This network deployment, including the FMC component, is a joint project between TDC Denmark and Ericsson. The FMC implementation offers advanced services to enterprise users. Enterprise...
Mastering knowledge of user profile is one of the technical cornerstones for service providers who handle a large amount of service consumption data and are well positioned to dynamically infer user interests. This paper presents a technology allowing to gather usage data from different multimedia services, create and track users profiles in real-time and monetize them by targeting content or other...
The emerging vehicular networks in the forms of intra-vehicle (InV), vehicle-to-vehicle (V2V), and vehicle-to-infrastructure (V2I) communications are fast becoming a reality and critical data is being exchanged with-inside and with-outside vehicle via vehicular networks. In this paper, we propose integrated info-security solutions for vehicular networks. The proposed solutions will ensure that data...
Transaction services such as payment or ticketing, but also security-sensitive services such as user identification or facility access control are increasingly executed in electronic format. With the concept of the SIM-based mobile wallet, this paper presents an integrative approach to electronic transaction services, combining the user experience of handling plastic cards with the convenience and...
The high availability of information provided through standards typical of the Web 2.0 world (e.g. RSS feed, atom, etc.) and services exposed by means of Web service API (see [1] for a list of more than 1300 APIs) leads to the development of new tools for the rapid creation of applications-called mashups-that combine these different sources. More specifically we refer to the event driven class of...
The dynamic provisioning of SIP addresses is a challenge when many devices and services are dynamically attached to an IMS network. Manual provisioning is too labor intensive for a telecommunications operator, and it is difficult to do it in a way that allows those devices and services access to all functionality of the IMS architecture. This paper proposes a novel way of handling the addressing of...
Web-IMS integration offers an opportunity to provide novel services that combine rich Web contents and IMS real-time communication functions. A rich Internet application (RIA) is a promising way to provide Web-IMS cooperative services for Web terminals without modification to the terminals. We propose an architecture that separates the IMS client function (SIP/RTP stack) from RIA as a shared SIP/RTP...
For telecom operators, the future lies in converging fixed, mobile and data services onto the next generation network (NGN). This paper discusses the relationship between grid and cloud computing, identifies gaps and overlaps in existing standards and identifies how grid and cloud technology could be exploited to improve the efficiency of NGN resources and to offer new ??data?? services to consumers...
Over-the-top Web 2.0 services are generating profound business and technical impact in the Telecommunications industry. On the business front the industry is reacting with deployments of Web 2.0-type services and by exploring non-traditional business models. On the technical side, Web 2.0 communications services such as social networking and micro-blogging are triggering a major change in the way...
