A framework for converged video services in the IP Multimedia Subsystem
ABSTRACT The IP Multimedia Subsystem (IMS) is being widely adopted as the standard service delivery architecture for Next Generation Networks. The IMS delivers rich IP-based multimedia services to end users. In order to fully utilize the potential of the IMS, the convergence of the World Wide Web and IMS capabilities is imperative. Services composed of Web 2.0 technologies and IMS based call control and multimedia capabilities are becoming popular. In this work, we focus on video service creation in the IMS, with an emphasis on user generated video content. We discuss the composition of richer video-enabled services, by converging technologies such as the IMS, Web 2.0, presence, location and social networking. We first develop a framework for video streaming over the IMS, using a Media Resource Function (MRF) and an Application Server (AS). We then demonstrate the flexibility and capabilities of our framework, by implementing rich services around video delivery which are suitable for both fixed and mobile terminals. We also provide the basis for a business model when offering these features and services. We further discuss how the video framework can be extended and made available as a web based service using REST and Parlay X APIs.

Conference Proceeding: Mobile contextual mashup service for IMS[show abstract] [hide abstract]
ABSTRACT: The Web 2.0 paradigm is all about the development of applications and content at the edge of the network by anyone. This ldquowisdom of the crowdrdquo type of activity resulted in a large number of applications being introduced in short time frames utilizing the telecom network as a ldquodumb piperdquo. However, IMS may open up the business opportunities for the cellular operators where they can take advantage of the openness of APIs offered by Web 2.0 dot-coms and still offer the flexible call control features of IMS. Thus, convergence of Web 2.0, mashups and IMS call control features have suddenly become a viable business model that will benefit the end users, cellular operators and application service providers at the same time. Rapid deployment of IMS can certainly be enhanced by successful blending of mashups and built-in features of IMS such as security, authentication, and quality of service. However, there is a lack of existing use case scenarios and experimental validation of supporting various web 2.0 applications over IMS. In this paper, we provide such a framework that helps to blend these two and highlight the lessons learned from the prototyping effort. We believe this framework and analysis of the results obtained from this experiment will be illuminating to cellular operators who plan to deploy IMS infrastructure and offer mash-up type services as well. A new type of service called ldquocontextualrdquo mashup is also described.Internet Multimedia Services Architecture and Applications, 2008. IMSAA 2008. 2nd International Conference on; 01/2009
Conference Proceeding: Palpatine: A P2MP IMS Video Share Architecture and Implementation[show abstract] [hide abstract]
ABSTRACT: In this paper we present Palpatine, an IMS application server providing a point-to-multi-point video share delivery service where a video share capable 3G device can capture audio and video in real time and send it lively to a group of 3G terminals wishing to receive it. Palpatine integrates seamlessly into IMS infrastructures without requiring any network modification and fulfilling all required standards. For this reason, Palpatine can be directly used over any IMS-compliant network without requiring the installation of any external application on current commercial video share capable mobile devices.Next Generation Mobile Applications, Services and Technologies, 2008.
