 from a perspective of collaboration with standards bodies. This workshop did bring together quite a collection of different standards bodies that are all working in the 5G space. The other interesting aspect of this is that there are many more than are here today as well. And one of the areas of collaboration that we have is something called the JCA IMT 2020. Which is going to provide us with a place where people can contribute what work is going on in all of the different standards bodies that are in the ecosystem. And this is going to be very important because there are so many things going on and so many things that are layered on top of one another. We need to identify the places where people are working together, where people are overlapping, where there are gaps that need to be filled. And this is the technical coordination that we're going to need to do to move forward and move this forward in a way that gets us to 2019 and having a fully functional 5G infrastructure. Well, like we've heard in this workshop already is that none of these items are really all that new. And so network management needs to be able to take a look at the network, create slices of the network, ensure isolation, ensure security, and ensure that you can build these systems so that you can have orchestrated pieces that drive the controller pieces that then feed into the thing that most people really care about. And that is how do you make money out of the network? So what are the ways that you can extract value and provide value for everybody all along the ecosystem of the 5G system? The one thing that I think the ITUT does very well is they look at a problem from the top down. They can look at a problem and identify what the use cases are, take that problem and identify the pieces that need to be put together in a framework or an architecture. And then once you define that, you can then define user stories and use cases to go along with that. When you have that, then you can define the actors that go along with the user stories and use cases. And then you can define the way that the actors need to work together in order to get to the problem that they're trying to solve. So that's one of the ways of looking at it from the top down. And one of the things I think the ITU is providing value in what they're doing in study group 13 along with the work that's going on in IT, in IoT, in study group 20, in security, in study group 17.
