QoE measurement collection in non-connected state
Example embodiments of the present disclosure relate to QoE measurement collection in non-connected State. In an example method, a terminal device receives, from an access network device, a quality of experience (QoE) measurement collection (QMC) procedure configuration indicating whether a QMC procedure is to be continued when the terminal device enters into a non-connected state. Then, the terminal device logs, in a logging buffer, QMC logging data of the QMC procedure performed at the terminal device in the non-connected state based on determining that the QMC procedure configuration indicates that the QMC procedure is to be continued when the terminal device enters into the non-connected state. In this way, QMC data collected in a non-connected state can be stored in the logging buffer so that the needed QMC data collected during non-connected state can be maintained.
