CAIPIRINA: Convergence towards All-IP: IMS Realization Issues for NGN Applications

01.10.2006 - 31.03.2008
Research funding project
The 3GPP IP Multimedia Subsystem (IMS) is currently expected to provide the basic architecture framework for the Next Generation Network (NGN) which will bridge the traditional divide between circuit-switched and packet-switched networks and consolidate both sides into one single network for all services. Therefore, the imminent commercial roll-out of IMS will have immense impact both for the migration of the core network as well as the integration of future mobile services and applications and will provide a significant step towards an All-IP network architecture for NGN applications. As an immediate and direct follow-up of the FTW projects N3-CAMPARI and P4-SIMS, and based on the rich expertise and the practical results (testbed, evaluation tools, etc.) gained during these very successful projects, the new application-oriented project N9-CAIPIRINA will focus on various aspects arising while the IMS is realized and introduced into existing mobile network infrastructures. Based on the existing ¿IMS in a bottle¿ testbed, detailed performance measurements allow to collect experiences in tuning IMS core networks. Another strong focus of the project is on exploring the rich opportunities related to the IMS charging architecture. Quality-of-Service issues to be investigated include resilience in the core as well as perceived QoS and charging for it. Last but not least, we also concentrate on Application Server Architectures.
