Section: 21.2.2 QoE Measurement Collection Deactivation
Content: The QoE Measurement Collection deactivation permanently stops all or some of the QoE measurement collection jobs towards a UE, resulting in the release of the corresponding QoE measurement configuration(s) in the UE. The deactivation of QoE measurement collection is supported by using UE-associated signalling. A list of QoE references is used to deactivate the corresponding QoE measurement collection job(s). Upon reception of the QoE release message in an application layer measurement configuration, the UE discards any unsent application layer measurement reports corresponding to the released application layer configuration. The UE discards the reports received from application layer when it has no associated application layer measurement configuration configured. The network can replace a QoE measurement configuration with another one by deactivating an existing QoE measurement configuration and activating another QoE measurement configuration of the same QoE measurement configuration type.
