 Good morning, everyone. And I'm very happy to be here to share with you my thought about 5G. So my topic is about building 5G-deterministic network and empower the digital transformation. So maybe you will curious about what is the 5G-deterministic network. So before we talk about that, let's have a brief review about the history of technology. So the steam engine was first invented in 1698 by Thomas Survey. Due to the low thermal efficiency, it's only been used for parking the water. But only after 70 years later, when Wards enhanced this steam engine, and it provided the deterministic power, then the steam engine was widely used in transportation, textile, and other industries. And it even brings the first industrial revolution. And the electric generator was invented by Siemens 1866. But only after Tesla invented this long-distance transmission technology, the electricity was sought as a deterministic source of energy. The internet was born in 1969 from Appnet. But only after a company like Google, Amazon, Alibaba, and Tencent provided this simple, deterministic online experience, the internet started to change people's life. So we can say all great invention can change the society, only when some determinacy was introduced. So we all believe 5G will change the society. So it's natural to ask, do we need to introduce some determinacy to 5G? So let's have a look how determinacy go on in the telecom industry. The diagram in left shows that when the network evolved from 2G to 3G and 4G, the telecom was losing the determinacy. And in the meantime, the internet company filled up the gap by innovating on the application layer based on the best effort network. Of course, this called over the top, and the end user paid for those value. The diagram in right hand shows that clearly the value shifting accordingly. So the revenue growth is very slow for operators only about 4%. But revenue growth has come to 400% for the OTT in the past 10 years. So for the next 10 years for 5G network construction, if the determinacy curve will not going up, then the telecom network business will not be sustainable. So 5G must do something to increase the determinacy. But what is the challenge we are facing? So you can say the connection will be a problem. The 5G will support more and more life-sensitive application like autonomous driving, the telemedicine surgery, the best effort network cannot meet those requirements. And the technology capability for telco also is difficult to catch up the industry evolution. By every year, more than 100 technology will emerging. And how to embrace those latest software technology, how to recruit the talents and return them and train them will all be a problem. And the engagement with the ecosystem partners still in a manual mode. So this efficiency can never fulfill the demands of millions of enterprise demands for the 5G. And also for collaboration in telco, most are still marketing and business driven. It's paper based collaboration compared to the engineer level collaboration. The efficiency is low. And the interface is ambiguity. So we can say to effectively running 5G, we are facing structure challenges. And those problems are correlated. So it needs a framework thinking. So here we provide this framework of our thinking to deal with those challenges. So you can say have a two collaborative circle. The inner circle is the internal resource how within our cross department to work in a unified platform and doing the continuous optimization. The external circle is how the operators to build a platform to effectively integrate the external resource like technology, talent, and the partners as well as the business service to meet those industry application demands. So the inner ring and the external ring are interactive and reinforcing and recycling in each other. So this framework specifically also provides four kinds of determinacy. That is connection, capability, collaboration, as well as computing. I will talk one by one. So first, the deterministic connection. So for 5G, the full stack guarantee is needed. So from bottom up, in the data plan, this MEC enabling the connection plus computing capability, such as UPF, should be deployed close to the end user and application on demand to ensure the bandwidth and latency. And as a high performance heterogeneous computing capability should adapt into different application demands. And in the control plans, the only slicing network will provide the diversity as well as the security. And in the management plan, the full autonomous driving experience through the domain autonomy and cross-domain administration will award manual process uncertainty. Second, for deterministic capability. As we know, for so many years for tech, we have a great solution strategy. But how to guarantee we have the right technology and the right expert to realize it is more important? So here we offer the technical portrait of a 5G deterministic network. You can see there are many new technology for each layer. For example, in the network layer, the TSN, the heterogeneous computing, and the cloud, the container with bare metal. And then in the management layer, such as modeling, the AI, the cloud native, and the open API. But in the application layer, also many new technology, like the model-driven, the big data, AI, and the security. So if our network architecture and the platform is common and open, so by nature, we have built an open capability and the talent cycle with the industry. So to sync up with the industry, it's also helpful for the internal employee to growth and the scale development. The deterministic collaboration. I believe it will focus on the value creation for end users is OK. So through the collaboration with the open source and the standard organization, the interface across the layer is more clear. For example, in the application and the intelligent, we use Equimus. In the management and automation layer, we use on-app. And in the network and edge layer, we use Acreno. So this open source cooperation framework will provide a code-based, clear, defined, and no ambiguity interface and boundary. It will bring a great benefit to improve the efficiency of the cooperation and to build a good industry division for work and to rebuild the mutual trust of industry. And together, we will enlarge the market and build a healthy 5G industry. Last but not least is deterministic computing. We all think 5G should provide more than connection. That's computing capability. But how to attract the industry to consume those capabilities? We need to build a live and prosperous ecosystem. So provide this application-friendly running environment, user-friendly operating platform, and developer-friendly torching or lab. So how to leverage the open source platform to achieve this is very important. So as a summary, I'd like to talk that two weeks ago, the Thomas Friedman gave an interesting talk in CGT. That's China going global think tank. The guy who thinks the world is flat and fast now he talked about the world is deep, including 5G. That means 5G will deeply involved in everywhere of the society and industry. So getting back to the determinacy is very important for 5G. So based on the deterministic connection, technology, collaboration, as well as computing, the 5G should provide a differentiated value and experience to end the user. So no matter for internal employment, employee or external partner, the consumers, as well as the enterprise customer. So easy to go, but waiting to stay would be my best interpretation for 5G. Thank you.
