Abstract: The future 6G era will enter a virtual digital twin world and realize the vision of wisdom connection and digital twin. The digital twin of mobile communication network needs to establish a high-precision mapping between the physical communication network and the twin communication network to ensure that the virtual data and the physical data are highly matched. To solve the problem of digital twin environment generation, this paper adopts the method of data-driven long-short term memory network to predict the time sequence of wireless channel, base station traffic flow and user mobility trajectory in mobile communication network, so as to construct a high-precision digital twin environment. Simulation results show that the proposed algorithm can accurately predict future time series data.
