This study analyzes Inter-AMF, Inter-5GC, and Inter-PLMN handovers in 5G/6G networks using a simulation framework that models UE mobility and A3-based triggering. Performance is evaluated across five HO types using metrics such as success rate, latency, and signaling overhead. Simulation results show that Xn HO offers less delay, while Inter-5GC and Inter-PLMN exhibit higher overhead due to core re-selection and authentication.
