Abstract
In this paper we want to present a real-time emulation platform for a multi-radio network environment that supports intersystem handover based on the principles of 3GPP System Architecture Evolution (SAE). The testbed is based on Nomor's Network Emulators for Application Testing (neat-box™) that have been extended with SAE core network components to support handover between different radio access networks. This work has been performed in the context of the EU funded project SEAmless Content Delivery (SEA). It allows the partners within this project to verify the improvement in the perceived quality-of-service (QoS) for mobile video streaming services achievable with their developed technologies. Especially handover situations between different radio technologies, as expected in future heterogeneous network architectures, will remain challenging for applications when it comes to avoid interruption or delay of the service. The efficiency of new technologies that cope with these challenges can be investigated and tested in a straightforward and conclusive manner.
