Method and Network Nodes to Manage QoE Measurement Collection During Relocation or Handover

A method, performed by a source network node operative in a wireless communication network, of transferring service of a terminal to a target network node, wherein the source network node has a Quality of Experience (QoE) Measurement configured for the terminal, the QoE Measurement implemented as a trace session in the source network node by a Measurement Initiating node, characterized by:

• in response to a pending transfer of service of the terminal from the source network node to a target network node, sending trace session information related to the QoE Measurement to the target network node;
• receiving from the target network node, feedback indicating whether the QoE Measurement will be continued or terminated;
• and
• notifying the Measurement Initiating node whether the QoE Measurement will be continued by the terminal or terminated following the transfer of service of the terminal from the source to the target network node.

A method, performed by a target network node operative in a wireless communication network, of transferring service of a terminal from a source network node, wherein the source network node has a Quality of Experience (QoE) Measurement configured for the terminal, the QoE Measurement implemented as a trace session in the source network node by a Measurement Initiating node, characterized by:

• receiving trace session information related to the QoE Measurement from the source network node;
• determining whether to continue the QoE Measurement after the transfer;
• sending to the source network node, feedback indicating whether the QoE Measurement will be continued or terminated;
• and
• if the QoE Measurement is to be continued, receiving (28) from the Measurement Initiating node one or more messages managing the trace session.

A source network node operative in a wireless communication network and operative to provide wireless communication service to a terminal prior to a transfer of service of the terminal to a target network node, wherein the source network node has a Quality of Experience (QoE) Measurement configured for the terminal, the QoE Measurement implemented as a trace session in the source network node by a Measurement Initiating node, the source network node comprising:

• a transceiver operative to exchange wireless messages with the terminal and other network nodes;
• and
• processing circuitry operatively connected to the transceiver, the processing circuitry characterized by being operative to:

• receive from the target network node, feedback indicating whether the QoE Measurement will be continued or terminated;
• and
• notify the Measurement Initiating node whether the QoE Measurement will be continued by the terminal or terminated following the transfer of service of the terminal from the source to the target network node.
