1. Storyline & Solution Telecom operators have natural advantages in networks, data, technology, and play a crucial role in the global economic digital transformation. They empower digital transformation in various sectors by leveraging cutting-edge technologies such as 5G and AI, driving the digital economy to develop in more fields and at a deeper level. Last year, China Telecom made the "ordering, activation, utilization, and assurance of 5G private networks" as the main theme of phase I of this catalyst. We are pleased to see that the outcomes of phase I, such as service agile provisioning, end-to-end service assurance, have been applied to more and more vertical customers. A new growth model driven by network based IT and data elements, has become the second growth curve for operators, with 5G cloud network business is the key point. By 2023, telecom operators in China have entered the phase of large-scale deployment of cloud network autonomous operations. They are planning and constructing automation and intelligent capabilities to cater to a broader range of specialties, encompassing a wider variety of products, and driving the automation and intelligence of more production and operational scenarios. Therefore, in phase II of this Atlas catalyst, we expand the original autonomous capabilities which support the E2E production process for 5G private networks into four aspects: "customer experience management, product operation, cloud network infrastructure operation, and general technology basement". Therefore, we have formed four special topics or scenarios for phase II to support more products and businesses, and continue to evolve towards higher levels of cloud network autonomous operation. This also perfectly aligns with China Telecom's vision of "Ultra-premium customer experience, Ultra-fast telecom services, and Ultra-intelligent cloud-network O&M". These 4 topics are introduced in detail as follows: 1) Customer experience management for verticals. Facing the market gap of CEM in the industry, we construct a customer experience evaluation metrics and deploy a 5G service quality assurance system that matches the industry's requirements, completing the construction of customized 5G private network operation and maintenance modules for vertical enterprises. 2) Closed loop of private network autonomous operation. We take the optical transmission network as an example to explain automated and intelligent process, such as business opening, fault management, and product service quality assurance, in order to solve problems such as long opening time, difficult fault RCA, and difficult SLA assurance. 3) Metro Cloud Network, which takes the operation and maintenance of vBRAS as an example, to introduce how telcos can solve the challenges brought by network virtualization, and CT/IT integration. 4) Digital twin technique. We will use digital twin as a typical technology basement and show its applications in network visualization, planning, and simulation deduction. These typical scenarios can be seen as pieces of jigsaw puzzle. They will form a full picture that will help you to have a more comprehensive and clearer understanding of how telcos enable the digital transformation of vertical industry, and finally achieve the goal of L4 autonomous operation.

Team Collaborations This project have 25 people from 6 companies form a joint project team, which includes two champions: China Telecom, China Union, four participants: Huawei, ZTE, AsiaInfo, Nokia. Guided by the vision of “Three Ultra”, based on the "four-layer and four-closed-loop" architecture of China Telecom's Autonomous Cloud-network O&M, the four vendors focus on the four directions of "customer experience, product service, cloud-network operation, and network digital twin" to carry out application innovation and realize single-domain autonomous. * Nokia: Build the autonomous capability of customer experience quality assurance. * Huawei: Build the autonomous closed-loop capability of service provisioning to operation. * ZTE: Build the autonomous capability of Innovative vBRAS network solution in new metropolitan area network. * AsiaInfo: Build the autonomous capability of network digital twin technology. Two carriers are responsible for cross-layer integration and E2E business process streamlining to upgrade cloud-network operation automation and intelligence, supporting service development and efficient O&M.

Catalyst Value These application scenarios have been deployed internally and externally by Chinese operators in the past year, and the benefits they have brought to vertical industry customers are evident. 1. The customer experience quality assurance capability has been deployed in five province branches. The handling time of customer complaints has been reduced from 4.5 hours to 3 hours, the timely handling rate of complaints has been increased from 80% to 93%, and the accuracy rate of identifying service quality anomaly has been increased from 30% to 75%. 2. The closed-loop of autonomous capability from service opening to operation has been piloted and verified by China Telecom. It has been deployed in multiple province branches, serving over 2000 government and enterprise clients in more than ten vertical industries. The autonomous level is increased from L2 to L3+, and the customer satisfaction is improved by 2.1PP. The provisioning duration of cross-province private line services is reduced from weeks to days. The annual revenue of supported services reaches billions of RMB. 3. VBRAS innovation capability in Metro Cloud Network has been piloted in production networks in 7 provinces of China Telecom, resulting in a decrease of over 10% in comprehensive network operation costs and an 85% reduction in fault location time. 4. The network digital twin capability has been validated in China Telecom Zhejiang province branch about the prototype system for key business scenarios of the Asian Games. It has been promoted to multiple other province branches as well. The network failure rate decreased by 68%, manual operation and maintenance costs decreased by 60%, and the efficiency of emergency handling increased by 60%. [IMAGE] 5. Usage of TMF Assets Since the first catalyst project we led in 2018, we have attached great importance to the use of TMF assets during the project implementation process, as well as the contribution and promotion of catalyst achievements to TMF standard projects. In fact, the AIOps working group in the Data&AI theme of the Collaboration project now comes from the AIOps catalyst project phases I to III from 2018 to 2019. Atlas Phase II mainly uses a series of related standards such as AN, AIOps, eTOM, DT4DI, etc. in TM Forum. * Refer to AN series standards as the goal and scope guidance for this project, important use case scenarios have been established. * Refer to the AIOps series standards to determine the application methods of AI technology during system development and operation, reducing system development and maintenance costs. * Refer to eTOM series standards to design the system framework of this project and improve system development efficiency. * Refer to the DT4DI series standards to study how to apply digital twin technology to enable vertical industry digitization and intelligence, and increase operational effectiveness. At the same time, the Catalyst project innovation achievements have been fed back to TMF assets. This year, we have successively exported IG1274F E2E AIOps system functional architecture, IG1274H AIOps capability management. And also, we have contributed the theoretical innovation and use case solutions of Chinese operators in the field of autonomous operation into TMF AN5.0 and DT4DI white papers, respectively. These achievements will be continuously iterated and updated within the standards working group. [IMAGE]
