 And I think from their ITUs and also the network perspective will, I think the 5G system, there are lots of areas we need to study. And some of areas has been identified in the focus group. For example, we have the network functional design with risk construction of the control plan and the user plan. And we also have some very important technology need to be studied like the FMC ICN network slicing and also network front-haul backhaul. And of course the FMC. And they also ask what's the most important part for the Wehrland network for the 5G standardation work. I think the FMC definitely is the most important one. If you back to the demo day, I introduced the FMC solution we call it UNIC. It's Unified Network Integrating Cloud. It's one of the solutions for the FMC. And FMC work is very difficult, it's complicated. We believe we need a long time to start it. For example, we need to solve the problem like how to achieve the unified authentication and a unified or convert the data plan for the fixed and mobile network and also double them. And also there are lots of technologies not mature. So I think we need lots of study on this topic. So fixed mobile convergence is the most important one I think for the Wehrland standardation work for the 5G system. I think as the chairman of the first group, I think firstly I think the first group have achieved a great progress in the 5G in MT 2020 through one and a half year. We work out lots of outputs including the network design, functional architecture design and also the network slicing. We also have lots of work on ICN and also fixed mobile convergence. I think we achieve lots of very good progress. And there is an amazing part and the exciting part is that it's not only about the technical report. We also have some PLC and a demo for 5G system. It's amazing. It's a new thing. We use the PLC and a demo to prove our idea. So it's not just the idea, we have proofread. So we can show the industry that we are not only for the technical report part. We have tested our idea, proved our idea. So I think this is very useful and available for us, especially for China Mobile. We grab lots of ideas from other companies and from other delegates. I think it's quite useful. So I hope at the next study period in the Star Group 13, I hope the Star Group 13 can carry on the work of the Fox Group and to collaborate with other SDOs and also the open source activities to progress to advance the work of the 5G globally.
