Research on 5G SA Network Shared Voice Solution

With the evolution and maturity of 5G SA network, aiming at the co-construction and sharing status, in order to provide the voice service, the paper summarized the SA sharing networking mode and voice service solutions. The technical solutions of EPS Fallback and Fast Return voice services based on handover or redirection under the current SA access network sharing scheme are studied in depth. The two solutions are analyzed, and the field tests are carried out. Finally, the test results are given and the technical feasibility is clarified.
