 So, it's glad to be here and every year we have a chance to talk and it's good morning and good afternoon everywhere. I'm Bill Ren from Huawei and it's really honored to have this chance to talk with all of you about the topic of open collaboration and proactive promotion for the maturity of autonomous network industry. So as we all say, COVID-19, the pandemic, it still accelerates the digital transformation. So according to the survey from the Harvard Business Review, the 95% of executives believe the digital transformation strategy is in their own industry because it's more important than ever before. So in addition, the survey shows that the 20% of the increase in ICT investment will lead to at least 1% increase in GDP. So by last year, more than 170 countries already have developed that digital strategy. So under the background of this global digitalization, the leading carriers in China such as China Mobile, China Telecom and Europe and Asia Pacific and Africa, so all like a telephonic or water phone entity, all have released their digital transformation strategy just as Dr. Feng also mentioned this. So how this digital development depends on the digital technology and how to do this continuous innovation. We also committed to do this digital development through the innovation. As mentioned here, the Ubiquitous Cloud Service, the progressive AI, the autonomous network is okay. And also as well as low carbon development benefit from these digital technologies. But Huawei's target, looking forward to the intelligent network 2030, the autonomous network as a core tech strategy for our communication network. So our long term vision is to build this, we call it self-configuration, self-healing, self-optimization autonomous network with this connectivity and AI technology. And at the same time, about 70% of the global carriers hope the autonomous network can reach to level three by 2024. And 94% of the carriers have implemented or planned to implement automation. And more and more carriers we believe in will embrace this autonomous network as their optimum choice in digital transformation. So let's see how this convenience would bring to our end user. So according to the latest web paper from the TMF forum, Autonomous Network will promote the, we call it a self-configuration, self-healing, self-optimization and as well as this zero weight, zero trouble, zero touch experience and they can develop all through the carriers planning, construction, maintenance, optimization, and operation life cycle requirement. But with fast development of a core technology such as just now we talk about SDN, OpenAPI, big data, all the devops of cloud-native technologies, all can enable the autonomous network, which are very, very basically prepared and required. But however, due to the complexity of the networking, such as a large number of elements, lots of impairment and lack of consistency and the network environment has a legacy and a complexity and also many legacy challenges such as the time consuming evolution and able to build everything from scratch. So all the things is mixed together and across domain and across carrier challenge as well. So basically we think there are three top challenges from architecture point of view, from the standards and the evolution KPI point of view and also the cross standard collaboration is also a very critical. So let's see how can we deal with these three challenges, three pillars to do the collaboration for accelerate the application for autonomous network in our industry. Okay, so first, we believe that to build a unified target network architecture is okay. Second, we need to define the autonomous network generation by generation and the level standards, which give us a unified evolution KPI to share the common framework and common understanding and common architecture. And finally, the standard developers organizations, the de facto standard and the standard collaboration also is important. So according to the target architecture defined by the TMF, the typical feature of the autonomous network is a, you can have at least two layers, is a single domain autonomy and as a cross domain collaboration. So the intelligent is layered, okay, the intent oriented resource machine interface is promoted under the resource management layer and the intent oriented service interface and the human machine interface that implemented the intent interface are promoted under, we call it CFS, consumer facing service layer interface. In addition to the net, autonomous network have made great progress compared with the legacy network in terms of the closed loop mode and the behavior. For example, the autonomous network will implement closed loop management, supervision and audit. The autonomous network are integrated with the network AI capability and have certain cognitive capabilities which can implement human intentions. So second, we think the autonomous network, how to define the level criteria and evolution methodology is also important. We define the evolution object from three dimensions such as O and M, operating and maintenance domain, there are six types of service and from service type and network domain, all three dimensions which have different levels. In addition, the industry should also pay attention to the established and the promotion, the evolution QPI to define what's the real level of autonomous driving network, so as a set of evolution systems that covers planning, construction, maintenance, optimization, operation, and the resource management from day to day, day zero to day one, day two operating. And the third point, as we mentioned before, is collaboration for cross-standard organization, it's quite important, so basically we think there are non-standard organizations working on the autonomous network domain and such as, and also in the open source, many open source projects are also interaction with standards to focus on the value creation of autonomous network and promote the large-scale development of autonomous network and as well as many partners also participate in this collaboration. So as we see from Huawei's point, we also provide one implementation of the autonomous network, we call it Huawei's autonomous driving network architecture and it's from the management and control and service operation, the network device and the infrastructure layer are management by the ADIN solution and from an integrated part of it. The native intelligence and the fault detection and prediction and other capabilities of network elements are very critical and basic for the ADIN solution. The ADIN's intelligence and the powerful digital infrastructure is provided by enhanced network element AI capability and the various different advanced features including the real-time energy efficiency optimization such as for wireless product, optical product and the excess broadband solutions. In addition to the native intelligence of the network element and in the control layer such as M master, we call it M master NEIE, M master MAE and M master NCE, all these layer solutions are in the service operation layer which includes automation and intelligence such as we call it OTIN, smart care and ADO solutions also integrated with AI capability in the business layer. So this is a three-layer solution and finally as we see the solution cannot be done by only one carrier. So in addition to the ADIN solution and the products provided from Huawei, Huawei also hope to strengthen the collaboration with the industry partners. Provide this fertile soil to promote the industry maturity and share these digital transformation opportunities based on this open collaboration. So we need to increase to promote the open source participation and contribute to the autonomous network use case such as the internet-driven networking, the 5G network slicing, cross-domain and cross-layer VPN, CNF, oxidation and the policy and control loops in the open source community. So the digital transformation data enables thousands of industry requires a joint effort for all the industry members to promote the collaboration with the business ecosystem, open source ecosystem and developer ecosystem. So we believe we do need to work together to promote the maturity of the autonomous network industry and share this great vision and opportunity and the common standing during this digital transformation journey. Okay, that's all from my side and I'm glad to talk with, discuss with all other participants here. Thank you. Very nice. Thank you. Thank you, Bill. And if you can stop sharing, then we can get on exactly. Thank you. Very good. For the attendees, if there are questions, please put them in the Q&A box and we will be able to answer them. The one question I had as questions come in is you showed the nice slides in two instances where you have standards organizations, you have open source organizations and then you have your ecosystem partners coming together and working together. I think that is fundamentally very positive for Linux Foundation and we appreciate that support from you across multiple projects, obviously. What do you see as an opportunity for the open source and the standards body like NNSE or KMFMF, GSMA to move even faster? They are already working very closely with us and I know you have been sort of chairing some of the standards organization work to enable us. How do you see those, any ideas on how we can move even faster with the standard bodies? Yeah, so I think it's always in quite a while before we're debating whether we need only the standards are open source, but we do find that now it's still have to call existing together and because in telco industry, the standards bodies do play an important role and because we have this kind of, what we call it, when the consumer business model, so we do need to cross into working with different, we call it cross domain, cross technology, cross when the solutions. So all the standards body do realize they are, they need a more fast iteration and to meet the, how to say the innovations and speed. But while we talk so many times, but still didn't find the quite much progress, we think it's the end, how to say, we need more use case driven or scenario based release to promote our open source implementation and the strength to do this, how to say to benefit to the industry. And everyone realize the value of open source, but many of them still stand outside of the community. They didn't dip down into the community. So I think we do need to put hands on the community and speed up the things, okay. Very, very well said. I mean, doing it, we call it doocracy here at the Linux Foundation. So if you do it, you will learn, you will benefit, you will gain and you will contribute, right? And so that's great. I think we are almost at time. I know we have a couple of more questions, but let me wrap up here just to keep us on schedule. Thank you, Bill, for the keynote. And we really appreciate it. Thank you. Thank you.
