The FuSeCo (Future Seamless Communication) Playground – located in Berlin – is a pioneering reference facility, integrating various state of the art wireless broadband networks. Two of its most important components are the OpenIMS Playground and the 3GPP Evolved Packet Core prototype platform. Both are discussed in the next slides. It is important to indicate that in both platforms, the different functional elements of the architectures are deployed as one or more virtual machines on dedicated 1U servers. In terms of access network hardware, femtocell are provided for 2G, 3G and 4G technologies. To complete this setup, several UEs are available.

The testbed addresses large and small scale equipment vendors, network operators, application developers and research groups to testwise deploy and extend their components and applications before market introduction in order to manifest their advance in the international telecom market.

In the context of Fed4FIRE, a fixed number of instances of both OpenIMS and OpenEPC will be provided as a federated service. Experimenters will be able to get exclusive access to such an instance for a given amount of time. During this time they can chance configuration parameters, add additional services, etc. These changes will be reverted when another experimenter gains access to the same instance later on. Every instance will also be characterized by the specific Radio Access Network infrastructure that is dedicated to it. This will determine which instance an experimenter needs to apply for his/her experiment. Also, some User Equipment is available to be included in the experiment. Also, some User Equipment is available to be included in the experiment. However, experiments that rely on an interaction between human users and UEs connected to the testbed require some sort of physical presence of the experimenter. In practice, such experiments must take place in the vicinity of the wireless infrastructure, which is usually at FOKUS premises in Berlin.

OpenIMS component

The Open IMS Playground (http://www.openimscore.org/) includes an Open Source Project ‘OpenIMSCore’ which focuses on the development of the IMS core network (HSS and CSCFs). The modular structure of IMS allows full or particular deployment of the OpenIMSCore components, which allows interoperability test of new components against the OpenIMSCore.

Open EPC component

FuSeCo Playground integrates various state of the art wireless broadband networks into a 3GPP Evolved Packet Core (EPC) prototype platform, allowing the rapid validation of new networking paradigms, and prototyping of innovative Future Internet and smart city applications. The current focus of standardization within the Third Generation Partnership Project (3GPP) is on building the foundation for future Telco networks to support coming wireless broadband access network types like Long Term Evolution (LTE) or WiMAX and concepts such as ABC (Always Best Connected), inter-technology handovers or (mobile) cloud computing. With the initial launch of Next Generation Mobile Networks of the NGMN Alliance based on the LTE/SAE (System Architecture Evolution) standard which was announced by many operators for 2010, the mobile industry demonstrates its efforts to move a true mobile broadband user experience from promise to reality. With this introduction, technology challenges have to be overcome and the focus of the industry is shifting to the key milestones such as testing and prototyping for deployment and operations, and to the availability of new services and devices.

Properties

Compared to the summary figure presented before, the situation at the FuSeCo testbed is characterized by the following properties:

  • Flack is not supported
  • FRCP is not supported. Therefore OMF6 and NEPI are also not supported.
  • Collectd and Nagios not supported, however a new measurement tool Packet Tracking Tool is introduced

The depicted resources are FuSeCo-specific: a fixed number of instances of both OpenIMS and OpenEPC will be provided as a federated service. Experimenters will be able to get exclusive access to such an instance for a given amount of time. During this time they can chance configuration parameters, add additional services, etc. These changes will be reverted when another experimenter gains access to the same instance later on. Every instance will also be characterized by the specific Radio Access Network infrastructure that is dedicated to it. This will determine which instance an experimenter needs to apply for his/her experiment. Also, some User Equipment is available to be included in the experiment. However, experiments that rely on an interaction between human users and UEs connected to the testbed require some sort of physical presence of the experimenter. In practice, such experiments must take place in the vicinity of the wireless infrastructure, which is usually at FOKUS premises in Berlin.
