Method and network nodes to manage QoE measurement collection during relocation or handover

A method, performed by a target network node operative in a Radio Access Network (RAN) of 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 by a first Measurement Initiating node, comprising:

• receiving, in an information element of a RELOCATION REQUEST message received from a Core Network (CN) of the wireless communication network, QoE Measurement parameters related to the QoE Measurement sent by the source network node to the CN in an information element of a RELOCATION REQUIRED message;
• determining whether to continue the QoE Measurement after the transfer;
• and
• sending toward the source network node, a message including an information element, the information element indicating whether the QoE Measurement will be continued or terminated following the transfer of service.

A source network node operative in a Radio Access Network (RAN) of a wireless communication network and adapted 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 by a first 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 adapted to:
• in response to a pending transfer of service of the terminal from the source network node to a target network node, send QoE Measurement parameters related to the QoE Measurement to toward the target network node in a an information element in a RELOCATION REQUIRED message sent to the Core Network (CN), and wherein the CN sends the QoE Measurement parameters from the CN to the target network node in a RELOCATION REQUEST message;
• receive a message initiated by the target network node, the message including an information element, wherein the information element indicates whether the QoE Measurement will be continued or terminated following the transfer of service;
• and
• send a message to the first Measurement Initiating node, the message indicating whether the QoE Measurement will be continued or terminated by the terminal following the transfer of service of the terminal from the source to the target network node.
