 First of all, a future network is not a specific network. It's more a generic concept for new network structures that offer services, capabilities, and functions that are not delivered or provided so far by existing technologies. And in this sense, this can be a total new network structure. It can be also a collection or combination of new and existing networks to a new operating structure. In this sense, I would say IMT, now upcoming IMT 2020 or 5G networks, they are really a characteristic or incarnation of such future networks. And in this sense, I can already say today, there are already a bunch of documents we have developed in the future network context that can be applied immediately to five upcoming 5G networks. So talking about 5G networks, we always have in mind service awareness, creating a bunch of new services in a very short time without significantly increasing deployment and maintaining costs, data awareness, handling huge data volumes in an easy and smooth way. Economic awareness becomes more and more important in our days. And last but not least, all in order to ease up access to new structures to users and stakeholders, although social economic awareness for such kind of networks. If you ask me about what the user can expect, I guess you should ask this question better to my 15-year-old son. He can give you better ideas about what's the upcoming features in gaming and digital entertainment. But I would say, from my point of view, in the end, the trend to be always everywhere with everything connected will continue, and we do know as we continue, it will increase. And in this context, though I expect many new applications related to smart environment, I could say to all what's related with digitalization of our society and economics. I would be happy if I could have already the whole picture in my head. Unfortunately, I don't. So what I can say today, that study group SIRTING is focusing currently on big data in the context of cloud computing. So big data as a service is one of the current emerging work items in our group. But again, if I look a little bit ahead on IMT-2020 5G networks, these networks will handle with hundreds of thousands of accesses of different types and will create an immense amount of data that have to be processed and interpreted in an appropriate way in order that they can handle. That means data aggregation, data interpretation and processing. So from this point of view for the future, I expect here in our 5G work, I expect a significant focus on work on this topic. I think not jumping immediately into the future, just looking shortly a little bit back, I think we had done a very great cooperation with ISO, IEC, community with two collaborative teams defining the definition, the basic definition in terms, as well as the architecture for cloud computing. And if I consider now how these documents are applied in several documents by other organizations or by ITU, I think we come here to a very prosperity future that our documents are really applied and are also considered to be applicable. And although if I look at the new challenges like the cloud interworking, that mean interworking between the cloud system of different types, or if we come out to distributed cloud computing, I expect here that conformance to our standards really will progress that work on these challenging topics. I think my concern I have here for the future, it's more coming from another direction. As you know, last week there was media published that there was an attack to the German parliament by hackers and also the Polish airline LART network were attacked from outside. And I think it's very important that cloud users, users means can be persons like myself, private persons, but it's indeed, it's companies, although it is important that they remain their trust in using cloud-based service. If this trust got lost, I guess then the continuation of cloud would be significantly endangered. So it is important that we focus also to secure these developments that we focus on trusted networks. And here, study group 13 has started in this recent meeting some months ago, an initiative and currently we have established a correspondence group between different SDOs to focus on the terms of trust and to develop first basic studies on trusted networks. I think in the end they are all correlated or linked to each other. I think we indeed, we continue with challenges in cloud computing accompanied by studies to create or to secure trust from the users to such services. And then it will be big data, but big data will be majorly done in context of cloud on the one hand and on the other side in the context of IMT5G networks. And here, like I stated before, I think we are not starting here from the scratch. Like I stated, already today, our future network studies have resulted in several documents which can be applied already now for requirements, architecture frameworks for 5G networks. And it's important, although one reason why it gives this interview to promote this, because we really have to avoid that other SDOs just duplicate our work. And indeed, we also have to avoid that we are not duplicating work of others. And for this purpose, we have created now a focus group on IMT 2020 exactly with a goal to sort out the complete terrain with other SDOs like 3GPP, IATF, IEEE, and so on and so on in order really to identify which areas each organization can work separately without big coordination. But more important, to sort out these areas where we have an overlap and where we have really carefully to cooperate. And I really hope, from my side, I'm really open for cooperation with these SDOs like 3GPP. And indeed, I always expect from them that they do the same. But I think with this coming effort, I'm really sure that for ITU, SLB, for the others, we will do in a coming task a great progress on this topic of 5G, IMT 2020 networks.
