As cellular networks grow with global deployments of 5G, so too do expectations among end users for sophisticated services. This is leading to increased demands on network operations and maintenance. The Phase II project will further explore how digital twin networks could help provide more innovative data services based on the visualization capabilities developed in Phase I. The project aims to address these challenges by using a tri-level digital twin network management solution to accurately visualize physical and computing resources and operation status. This will enable complex network failure playback, which can be used for root cause analysis and knowledge generation. The solution will also be used to predict new business opportunities and verify their feasibility. The objectives of the project are to: * Improve the robustness of the network. * Simplify and make operations more efficient. * Enhance customer experiences. * Deploy the solution quickly and expand it on CSPs' existing network
