Implementing Conditional Conference Call Use Case over IMS and Non IMS Testbed - an experimental results through comparison Approach

摘要

IP Multimedia Subsystems (IMS) is a technology leading towards Next Generation Networks (NGN) which has the ability to provide converged service regardless of any access networks. This paper presents a conference call use case application and the realization of the application based on both IMS and non-IMS infrastructure design approaches. This paper also presents our findings in comparing the two approaches, and the identification of technical gaps and potential issues on IMS in supporting conferencing services through our exploratory and developmental research.
