The handover could occur between 5GS and EPS with or without N26 interface. The success or failure of the handover between 5GS and EPS directly impacts the users’ experience, especially for the service of voice over IMS. When the handover occurs via the N26 interface, the handover may succeed or fail on the N26 interface. The performance of handover between 5GS and EPS needs to be monitored, and for failure cases the measurements with specific causes are needed for trouble shooting.
