Question: In NR-DC (New Radio-Dual Connectivity) scenarios, how is QoE (Quality of Experience) measurement continuity ensured during inter-MN (Master Node) handover with a change in Secondary Node (SN), according to 3GPP standards?
Option 1: The target MN autonomously determines the new SN-associated QMC (Quality of Measurement Configuration) without information from the source SN.
Option 2: The UE (User Equipment) directly informs the target MN about the previous SN's QMC configurations during handover.
Option 3: The source SN provides the source MN with SN-associated QMC configuration information, which is then transferred to the target MN during the handover procedure.
Option 4: QoE measurement continuity is not ensured in scenarios involving both inter-MN handover and SN change due to inherent network limitations.
Explanation: Ensuring QoE measurement continuity during complex mobility scenarios like inter-MN handovers with SN changes requires seamless information exchange. The correct approach, as per telecom principles for maintaining service quality, involves the source SN sharing crucial QMC configuration details with the source MN, which then relays this information to the target MN. This coordinated handover process ensures that the new network setup can promptly resume QoE measurements without interruption, aligning with 3GPP's focus on enhancing user experience through standardized, efficient network operations.
