 In Chernobyl's will, network slicing is a key and emerging technology for 5G. It can enable a logical and isolated and end-to-end network for vertical companies, I mean vertical customers. Compared with traditional network measurement, traditional network measurement is targeted at network function and network element-based measurement, especially on f-caps. So when we introduce network slicing, we will add new authorization functionality into our network, especially to how to create, how to update, how to scale in, scale out, how to operate network slice for vertical companies, that will add more authorization and more measurement function inside or in the top layer of traditional network measurement system. Network slicing for operators, we think it can enable new services, it's a new business model for vertical customers. The benefit is that we can provide functionality customization, we can customize functionality and some performance and provide new services like resource service and while adding the service to third party, to vertical companies. So everything customized for you, for vertical customers, that's a benefit, I think. You know, China Mobile is very active in promoting network slicing technologies, including the standardization, test, trial and solution and built ecosystem. Now, today we built a demo show in the IT workshop 5G. We can see, we propose the authorization and measurement for network slice in 5G. We give an overview of architecture for slice authorization and measurement. You can show some slice measurement authorization based on the traditional measurement system and authorization system and existing OSS system, like network function measurement. We can manage the common infrastructure, including the ran input transport, including the HDC and core DC. And now we built the system to base the many open source system, work with BOPT and Eurocom and China OAI system, open source. So here, you can see slice measurement system, we show 5 key functionality, the first one is the slice market. We can allow vertical customers to select what they want for the slice, including the slice type and bandwidth and other performance requirements. And then we can design slice template based on the 5G new functionality. For example, 5G is an SBA architecture. We can customer network function based on the NF service. And then we design the NF network function, and then we design the device network slice based on the service and the network function. And then we can provide some maintenance and configuration information, including the network slice selection assistant parameter. And after that, we can see how many templates already created and we can deploy and terminate the slices. We can, based on the customer requirements, we can monitor many status of the slice, like the CPU resource and number of users and others. We can see the infrastructure measurement, how many slice built. So now I ask the supporter from BLPT to introduce the detailed implementation on that. Thank you. Now I will introduce the details of our demo. You might see here, we have several machines. And the middle four is our virtualized infrastructure. And these two is the run part. So we have two slices on these machines. One is for EMBB and the other one is for MOT. These two base stations connect to these two slices differently. So you might see from my phone, I have created this network CMCC, China Mobile. This phone is connected to the EMBB slice. So it's optimized for the big traffic service. And also we have another slice. You may see it now. This one is already connected. And another one is analysis for MOT. So based on our slice management framework, the user equipment can connect to different services. And based on their requirement, applying this slice management framework, the operators can reduce their campaigns and opacs greatly. And also users can promote their service quality.
