Quality of Experience (QoE) Measurement collection is continued from a source network node (200) providing service to a terminal (210) to a target network node (200) following a SRNS relocation or inter-RAT handover of the terminal (210). When the source network node (200) is preparing for the transfer of a terminal (210) for which a QoE Measurement is configured, QoE Measurement parameters, which have been received by the source network node (200) from a first Measurement Initiating node (200), are sent from the source network node (200) to the target network node (200). The target network node (200) provides information about the handling of the ongoing QoE measurement to the source network node (200), e.g., whether the QoE measurement is to be continued or terminated. The source network node (200) updates to the first Measurement Initiating node (200) whether the target network node (200) will continue the QoE Measurement. If the target network node (200) has a QoE Measurement configured by a second, different Measurement Initiating node (200), it may continue the QoE Measurement under that configuration, and send to the source network node (200) some or all related QoE Measurement parameters.
