 I'm here at the ITU in Geneva, and I'm very pleased to be joined by Andrey Kutcheryavi, Chairman of Study Group 11 on Protocol and Testing Specifications. Andrey, welcome, and thank you very much indeed for joining us here today. Thank you very much. So I'd like to ask you a few questions. Could you please explain to our viewers, you know, the role of Study Group 11 and what are some of the main achievements from the last study period? Study Group 11 is one of the important study groups of International Team Education Union standardization sector. During WTCA, the responsibilities of Study Group 11 was detailed, and we can see that our responsibilities now is, first of all, signal and protocol requirements, including IMG 2020, the testing specification for all types of network services and equipment. And last little role of Study Group 11 is counterfeiting of IST devices and combating counterfeiting devices stolen. So about the achievements of Study Group 11 over the last study period. First of all, of course, there are many recommendations regarding to signaling system. To signaling system, modern signaling system, there are a couple of recommendations for software-defined network. And our software-defined network architecture will be used for most important new technologies for IMG 2020, for tactile internet, for augmented reality, and so on. The next very big achievements, in my opinion, this is the Established Conformity Assessment Stealing Committee. Before it, there is no committee which can collaborate with another standardization body on certification scheme. Today, we have a good progress on this work, and we will hope that not so long, and we will establish the ITU Flash IEC certification scheme. So during the last study period, we established new questions. As I said previously, now one of the most important activities of our study group is counterfeiting and mobile device theft. This work was started during the last study period. No double VTCA, and on VTCA, this direction of investigation was approved. The second point is very important, too. This is not a typical problem, but the problem is very big. This is a voice over long-term evolution, and video over from long-term evolution systems. There is no good decision up to now. We are working together with the European Telecommunications Department Institute, Technical Committee IND together on this problem, and preparing some draft of recommendation, and it's a good basis for our next step during this study period. The following is, of course, a very interesting point. We developed and approved a new recommendation about internet measurement speed. It's very important because this is the objective method for acceptable to all for measurement of internet speed. And some organization achievements, first of all, we signed the collaboration agreement with the European Standards Institute Technical Committee IND. And the second, we created two regional groups, regional group from Africa region and regional group from RCC. RCC is a common wealth of the Soviet Union. The regional group is very important in our opinion because the main goal of this regional group will be to develop recommendations. We have not more recommendations, unfortunately, now from Africa. We think that we can give more recommendation from RCC to regional groups. I think it's the most important achievement during the last study period and, as I understood, this is a free point, more activity, more new technologies, and more collaboration. And it seems study group 11 is the leader on conformity and interoperability testing. Can you please explain a little bit more about this work and why it's important for our members? This is too part of a big testing problem, first of all conformance testing. What we can give from conformance testing, this is the guarantee that the equipment will be work-good as separate part. What is the focus of interoperability? Interoperability testing gives us the guarantee that all equipment from different vendors will be work-together high quality. It's a very big problem from last study period, but study group 11, first time, was worked on testing at the 2005, and we have a good experience, and during last study period, many recommendations were developed, the big set of recommendations were developed. And one more problem for interoperability, this is benchmarking testing. What is the benchmarking testing? We are sure that after conformance and interoperability testing procedure, the equipment, the services will be work-good in operation, but if we can see overload conditions, we need some another procedure with benchmarking. We have a special question on benchmarking and during last study period, we prepared the big set of recommendations. Today, today, what today we see today, there are many new technologies, Internet of Things, this is the enormous number of terminals, the next point, which is, I'm sure, which will be widely implementation during this study period, this is tactile Internet. Tele-Internet request from the network one millisecond latency, for example, the existing generation network request 100 milliseconds, but it's only for voice. Good quality for voice, the latency should be 100 milliseconds. If we see on the duct internet is one millisecond, which is the new methodology of testing, this is the new specification, but we are ready to work on this matter, and so on, augmented reality and so on, many new technologies, it's very interesting. And speaking of voice, one of the challenges for the industry is ensuring a high quality of voice over LTE networks. I understand your work, your study group is doing some work on this, can you please explain a bit more? We are working on this problem together with European International Standards Institute, technical committee, because not only our problem is the problem of the world, voice over long term evolution and video over long term evolution, unfortunately during the study period, there are many problems during the operation. Now we are preparing the set of standards. I'm sure that the vendors and operators will use the standards, the equipment will be good and this equipment will provide the good high quality in operation. And another challenge for the industry is counterfeiting of ICTs, and our members have called on ITU to do some work on this, I understand study group 11 is doing work on counterfeiting, can you please explain what kind of work is taking place there? It's not new problem today, we can see how to decision this problem. Last time we worked on counterfeit during the last study period, we prepared the report about what is counterfeiting, how we can combat counterfeiting, but now with this new study period, I'm sure that before middle of this study period, we prepared recommendation set on counterfeit for counterfeiting ICT device and for combating counterfeiting with ICT devices stolen, it's one more big problem for counterfeiting area. Okay, Andrei, I'd like to thank you very much indeed for your time and I'd like to wish you the best of luck and success for the next study period. Thank you very much.
