Intelligent gateway systems have evolved to seamlessly offer location-aware and multimedia services, allowing multi users to roam among multi service domains. In the past decade intelligent gateways have been implemented to support context-aware multimedia services with network convergence and service reasoning mechanisms in multi domains. However, recent researches have to consider multiple events...
In this paper we present the experimental findings in comparing standard IMS with proprietary non-IMS solution from the aspects of session control mechanisms and service management capabilities support in the context of providing automated converged services. The methodology used in the experimental study is via developing an automated converged communication service called CommRobot (Communication...
As telecom service providers worldwide are deploying next generation networks (NGN) to offer multimedia services, they have recognized that traditional network management principles based on ITU-T's telecommunications management network (TMN) model is no longer sufficient. To provide multimedia services that would satisfy customers' service quality demands, they must implement the new management model...
Ubiquitous connectivity today allows many users to remain connected regardless of location with various kinds of communities. This paper studies challenges in building trusted communities that encompass both new users as well as users already possessing credentials from other well known connectivity providers, federations, content providers and social networks. We postulate that trusted communities...
Service providers aspire to increase number of new clients and loyalty level of those clients who have already connected to them. Today is not enough just to increase a number of media services for this purpose, it is very important to guarantee the best quality of service (QoS) level in a service level agreement (SLA). The SLA has set of aspects which define threshold parameters of a service performance...
Service delivery is vital for the success of IMS network in telecom. Current approaches focus on combining existing services into a new composite service. However, there are further requirements for enabling telecom operator to dynamically personalize, manage and enhance user services at runtime outside of the application logic itself. We observe the need and present the SCL (service control layer),...
The IP Multimedia Subsystem (IMS) has emerged as next generation value added communication services including mobile multimedia broadcasting, multimedia conferencing, push to talk and presence etc on top of all IP networks. Offering multimedia streaming services across heterogeneous fixed and mobile networks have faced many challenges e.g. security, QoS, mobility and services management. In this article...
New/next generation networks aim to provide mutual trusted IP based networks for a multi access network and innovative services tailored to users needs. NGN architecture has been the purpose of several studies within organism of standardization like ITU-T and ETSI. We present here a literature about NGN architecture (NGN) and next/new generation service (NGS) requirements: details about functionalities...
