Experimental finding in implementing “CommRobot” - Comparing IMS and proprietary solution

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 Robot) as the use case for comparison. The CommRobot use case is aimed to demonstrate the capability of enhancing user flexibility in choosing how and when services to be delivered regardless of access methods i.e. interfaces, devices or networks. Together with the comparison, we also present the experimented CommRobot test-bed, discussion of our findings and the challenges we identified in implementing the use case service using both standard IMS and non-IMS proprietary solutions.
