20 QoE Measurement Collection

25.3003GPPGeneral descriptionRelease 17Stage 2TSUniversal Terrestrial Radio Access Network (UTRAN)

With this feature, the network can configure collection of measurements from the UE. The feature defines QoE measurement configuration and measurement reporting containers, and the feature uses the MDT framework [14]. QoE measurement configuration received from OAM or CN is encapsulated in a container, which is inserted in a Measurement Control message and forwarded to the UE transparently. QoE measurements received from UE higher layer are inserted in a container in a Measurement Report message and sent over SRB4.

The supported service types for QoE Measurement Collection are QoE Measurement Collection for streaming services and QoE Measurement Collection for MTSI services.

The QoE measurement configuration is supported in CELL_DCH and CELL_FACH states, whereas the QoE measurement reporting is supported in CELL_DCH state only.

Both signalling based and management based initiation cases are allowed. For the signalling based case, the QoE Measurement Collection is initiated towards a specific UE from CN nodes using the MDT mechanism as described in clause 5.1.3 [14]; for the management based case, the QoE Measurement Collection is initiated from OAM targeting an area (without targeting a specific UE).
