Section: 13.4.4 QoE Measurement Continuity for Mobility
Content: For ongoing sessions, QoE measurement continuity is ensured during mobility in NR-DC, e.g., during inter-MN handover (with/without SN change) and SN change scenarios. To ensure QoE measurement continuity during SN change, the SN-initiated SN modification procedure and/or the MN-initiated SN modification procedure can be used to provide the information about the SN-associated QMC configurations to the MN. The MN can then transfer this information to the new SN during the SN Addition procedure. To ensure QoE measurement continuity during inter-MN handover with SN change, the source SN should provide the information about the SN-associated QMC configurations to the source MN. During the handover procedure, the target MN is provided with all the information that the source MN has about the SN-associated QMC configuration. If the MN configured the UE with QoE measurements, every subsequent MN serving the UE can configure and release the RAN visible QoE measurements.
