 I'm here at VIT Studios in Geneva and I'm very pleased to be joined by Leo Liemen, Chairman of Study Group 13 on Future Networks, IMT 2020 and Cloud. Leo, thank you very much indeed for joining us here today. Thank you very much for being here. So could you please explain to your viewers a little bit about your study group's work on Future Networks and where we might see this technology play in our daily lives? First of all, SCOBE of Study Group 13 covers three very big and important areas for ITUT. First is IMT 2020, you mentioned it. Secondly, it is cloud computing and big data. You miss big data, but big data is a very important part we have beside cloud computing. And thirdly, it's trusted networks or trust. Coming back to IMT 2020, I think it has a biggest focus in other communities. It's called 5G and we have started now work on during our recent study group meeting, defining the first delivery packages for this year and for next year that will cover architectural view, will cover softwareization, orchestration and will although cover aspects of trust. So let's say we have a future of standards work largely driven by 5G and trust. Is trust something that can be standardized and how do you develop technical standards for trust? Good question. I'm not sure whether or not it's so good so far. Trust is in very important aspects for future networks, not only for 5G, it's for all networks. And it's based on the fact that networks become more and more complicated and complex and without trust or means of trust implemented in the networks. You won't be able really to succeed with future applications that require that the users have trust in the application and the network and with the applications are running. Considering trust, I think if you look at the meaning in normal life, trust is something when I tell I trust you, I mean that I believe in your correctness, in your integrity, in your truths and that the first step what we have to do now, we have to transform this into technical means, means security, reliability, dependability. Study Group 13 has already done here first important steps during last study period by defining technical terms of trust with currently still let's say a little bit more refined with our colleagues from Study Group 17, they have to lead on security. And in parallel, we although develop here our plan to develop recommendations related to trust that have a focus on trustworthy architectures or network architectures as well as all the trust in the area of cloud computing and big data. And speaking of big data, you mentioned that earlier, you know what's the relationship between big data and cloud and what are some of the key standards that your group has developed in these areas? Yes, so first of all the big data and cloud to cloud is a mean in order to realize big data as a service. On the other side, cloud is dealing with big data, so big data is an aspect included in the standardization of cloud. And in this aspect, we have developed already recommendations that exactly and much more precisely than I do it now in this interview defined and explained the relationship between big data and cloud. And like I said, big data as a service will be very, very important. That may be also help for applications related to 5G verticals like IoT, very important there. Then in general, big data driven networking is a very important aspect that where we start now, first work items and we expect here recommendations with the next, I would say 24 months. And an important part of your work leading towards 2020 is supporting innovation in 5G wireline networking. What are some of your achievements in this area? That's what you mentioned here. That's exactly the focus we have. You know, 5G is very big and 5G has a strong mobile part and radio part. Indeed, radio part is done by ITUR. The mobile part will be done partly with us, but I think we cannot close our eyes that industry is doing here a lot although in 3GPP. But exactly the wireline part, the wireline access. That is this part where we expect our deliverables. And as I mentioned already in the beginning of the interview, when I talk about architecture and recommendations on softwareization, I have a strong and fixed mobile convergence. I have a strong more focus here on the wireline part of 5G IMD 2020 networks. And like I said, I expect here all the cooperation with other STOs because it's an issue that our members of study group 13 are involved in several groups. So it's important that we have a coordination and harmonization between these groups for this purpose. We have also established a JCA of IMD 2020 in order to secure that these parts, these wireline part developments are done in good coordination and positive coordination with other STOs in order to achieve here with big success. Like I said, first deliveries within the next 8 to 24 months. And we're here at the beginning of a four-year study period and the work of your group covers many topics. Are there any other topics that you'd like to highlight for the next four years? I think what will be an important area is in cloud, everything as a service, for instance, further developments in trusted networks. But we should all do not forget we have a so-called question 5 in study group 13 dealing with IMD for developing countries or it was an old name. I think the new name, I forgot now, it's related to innovations and networking for developing countries. And I think to support them, that will be a big, big goal for us and a big commitment for myself as a chairman of this group for the next four years. And what would be some of the challenges that these countries would require, you know, special specifications or new worklets? That is what we try. I can't tell you today, but based on contribution we received at the last meeting, we have started exactly to analyze by question 5, by the experts of developing countries, because this question is based on members who come from Africa and other developing countries to analyze which topics are important for them. And based on this, we will ask then our experts, our reporters and editors to develop in parallel to, by established standards, we all ask them to develop appropriate guidelines for the developing countries. Very interesting. And I'd like to thank you for your time. And I would like to wish you the best of luck with your new study peers. Thank you so much.
