Framework for IMS Service Scenario Implementation
نویسندگان
چکیده
This paper presents an experimental framework for implementation of an IMS/NGN reference service scenario by means of open source software. Multiple service enablers are deployed to build this service scenario. Interoperability tests between the deployed IMS entities and user equipment are carried out, as well as performance measurements of signaling overhead and delay of different IMS procedures involved to support the service scenario. Then, some preliminary results are obtained. After that, the IMS prototype is integrated with in-lab UMTS/HSDPA and WLAN networks to test IMS procedures in more close-to-real environment. Additionally, practical experiences with the IMS testbed deployment are discussed.

A Converged IMS Client for the IP Multimedia Subsystem
The IP Multimedia Subsystem (IMS) has been developed to provide a single platform that offers many different converged services, over multiple access technologies, with several different end user terminals. It aims to unify the current disjoint point solutions offered by network operators, with the goal of reducing CAP-EX (Capital Expenditure), OP-EX (Operating Expenditure) as well as reducing ...

Abstract. This article describes a framework for the integration of e-learning services. There is a need for this type of integration in general, but the presented solution was a direct result of work done on the IMS Learning Design specification (LD). This specification relies heavily on other specifications and ser-vices. The presented architecture is described using the example of two of suc...
