Completed 5G network deployment. Further, the following 5G NSA network sharing scheme can be used to provide 5G services: the contractor completes the 5G NSA network coverage, and provides 5G services for the contractor's users and the sharing party's users. Specifically, the contractor's 4G anchor cell can broadcast the contractor's 4G carrier and 5G carrier, and the sharer's 4G cell can broadcast the sharer's 4G carrier.
