Abstract: Based on the demands for wireless bearing services of urban rail transportation, the main wireless bearing services of urban rail are introduced and the demand for broadband wireless services for the future is envisioned. The main options to meet these demands include establishing a virtual private network by slicing and MEC and utilizing the 5G network equipment of operators; sharing 5G base stations with operators and building a small core network independently; using operators' 5G core networks and wireless networks and providing UPF and MEC independently; leasing operators' frequencies and providing a self-built network. The advantages and disadvantages of each of the scheme above are compared and analyzed.
