Design and key technology of digital twin body for mobile network

To solve the problems of high risk, high frequency, significant difficulty, and the challenge of ensuring reliability when implementing dynamic network operations directly in actual networks, this paper proposes a network architecture natively supporting digital twins for mobile networks and provides a detailed design of the digital twin body within the network architecture. This design creates a virtual twin of the physical network entity in a digital manner, empowering the network with capabilities for evaluation, analysis, management, prediction, and optimization. The paper also studies the data technology, modeling technology, and simulation technology within the proposed scheme. Finally, based on the proposed architecture and key technologies, a network digital twin platform is designed, and simulation verification is carried out on this platform for the scenario of network slicing business opening. The experimental results indicate that the proposed scheme can accurately and efficiently achieve verification of slicing parameter con-figuration, business volume prediction, and effectively enhance the efficiency of business opening.
