Method and device for managing qoe of terminal in wireless communication system

A user equipment (UE) for managing quality of experience (QoE) in a wireless communication system, the UE comprising:

• a transceiver;
• and
• a processor coupled to the transceiver and configured to:
• establish a radio resource control (RRC) connection with a base station,
• transmit, via the transceiver, UE capability information related to logged QoE measurement to the base station,
• receive, via the transceiver, from the base station, logged QoE measurement configuration information including at least one of trace reference information, trace collection entity (TCE) identifier (ID) information, area configuration, or logged QoE PLMN list information,
• log QoE measurement results based on the received logged QoE measurement configuration information,
• transmit, via the transceiver, availability of logged QoE measurement results to the base station,
• receive, via the transceiver, a QoE data retrieval request from the base station, and
• transmit, via the transceiver, logged QoE measurement result data to the base station,
• wherein the processor is further configured to:
• camp on a new base station,
• receive new logged QoE measurement configuration information from the new base station, and
• determine whether to perform logging or reporting based on the logged QoE measurement configuration information and the new logged QoE measurement configuration information.
