 Today I will introduce our best network solutions. As 5G launched in many operators globally, it also brings new service to the network. First is the voice service. Traditional, we have VOTE service in the network. But with 5G, we bring 5G new calling service to the network. It combines voice and video together. And the second one is the video service. Traditional, we only have video on-demise service, but right now more and more live streaming service brings the network. And third is the cloud gaming service. Traditional, we only have single user gaming, but now we have a lot of cloud gaming services in the network. So this new service actually brings new requirements to the 5G network. First for voice service, traditional only for the voice quality of voice 4. What is MOS over 4.2? That's the indicators for voice quality. With VOTE service, if the voice quality is higher than 4.0, it's pretty much enough. But with the 5G new calling, we require most value higher than 4.2 to guarantee there's no storing for the voice service. For live streaming, with video on-demise service, we only require higher support on the download, but for live streaming service, we require both uplink and download to meet the HD video ratio. And for gaming, with the single user gaming, we only require signaling plan, latency, to meet the network requirement. But with the cloud gaming, because there are so many data streams in the user plan, so we require end-to-end latency less than 100 milliseconds. So with all the requirements for the new service, Huawei brings new standards for the batch network. That is actually service anytime, anywhere. So we define that if we can guarantee the service selling throughput and uplink throughput and also end-to-end latency at a busy hour at cell age, that means we can support a higher user experience for the whole network. And to achieve this goal, we have Huawei's smart care solutions and we have three key technologies to support we can meet the goal. First is the voice quality optimization. We have specific five-second slicing optimization and we can slice the voice service at five seconds. That means we can identify all the user experience issues for the voice service. After we identify those issues, we can play demarcations to demarcate if this problem is related to RAN network or IMS network and then we can perform the root cause location to optimize this problem. And the second is the grid-level video optimization. So we can demonstrate the actual video at a grid level and to show which grid has the user experience issue. And then we will correlate with the network data, like MR data to perform the troubleshooting. If this experience issue is related to network coverage. It's like an AI kind of solution? Yeah, we will use AI technologies in this. To optimize. Yeah, to optimize because we have this MR based geolocation and if we want to perform RF optimization we will use AI to modeling the coverage of the wireless coverage of the whole network and also we will identify each grid has specific network issues like weak coverage or coverage overshooting and that requires AI to perform the root cause location. And for the latency optimization, latency problem is always very complicated in the network so it will require multiple network elements that cause this problem. So we have this cost domain association analysis. We will bring all the data at different interface and do the correlation of all the data and to identify which part has these latency problems. And through this correlation analysis we can identify the problem and then improve the end-to-end latency. And this is happening now? Yeah, it's already realized and we have some project ongoing in the China region. So it's already like all the numbers on the screen it's already verified in the project. And it's called smart care? Yeah, the name of the platform is smart care. It's the brand name that we use multiple tools like for probe system and also like network optimizing system but we use the same name as Huawei smart care. Alright, cool. It's great to have a better quality and you can do 4K anytime, anywhere. That's right. Huawei best network solution. Alright, cool. Next slide.
