4.7 Data collection, reporting and exposure for 5GMS |R17| p. 44
4.7.1 Reference architecture instantiation p. 44
The abstract data collection and reporting architecture defined in clause 4 of TS 26.531 and depicted in Figure 4.2-1 of TS 26.531 is instantiated in the 5G Media Streaming architecture as shown in Figure 4.7.1-1 and as defined below.
The functional elements in this instantiation are defined as follows:
- The role of the Application Service Provider in the abstract architecture is played by the 5GMS Application Provider.
- The Data Collection AF for 5G Media Streaming is instantiated in the 5GMS AF.
- The Direct Data Collection Client for 5G Media Streaming is instantiated in the Media Session Handler. This takes logical responsibility for the UE data collection activities of the Metrics Collection & Reporting and Consumption Collection & Reporting subfunctions and the subsequent reporting of this UE data via reference point M5. It also takes logical responsibility for the logging of ANBR-based Network Assistance invocations by the Network Assistance subfunction and their subsequent reporting to the Data Collection AF instantiated in the 5GMS AF via reference point R2.
- The Provisioning AF of the Application Service Provider is not instantiated in the 5GMS architecture. Data collection and reporting is instead provisioned using the procedures defined in the present document.
- The Indirect Data Collection Client is not instantiated in the 5GMS architecture. Indirect reporting of UE data is outside the scope of 5G Media Streaming.
- The role of the AS data collection client in the abstract reference architecture is played by 5GMS AS. This may be deployed as a trusted AS within the 5G System or deployed externally.
- The Event Consumer AF is instantiated in the 5GMS Application Provider as a consumer of 5G Media Streaming events from the Data Collection AF.
R1
This reference point is not instantiated in the 5GMS architecture.
M1
Provisioning of data collection and reporting features in the Data Collection AF.
R2
Direct data reporting by the Direct Data Collection Client to the Data Collection AF of ANBR-based Network Assistance invocations.
For the provision of QoE metrics and consumption reports, R2 is instead logically realised by the combination of the following components:
M5
- Internal interfaces between the Direct Data Reporting Client and its subordinate functions, namely Metrics Collection & Reporting and Consumption Reporting & Reporting.
- Internal interface between the Media Session Handler and its subordinate Direct Data Collection Client function.
- Reference point M5, as defined below.
- Internal interface between the 5GMS AF and its subordinate Data Collection AF function.
Direct data reporting by the Direct Data Collection Client to the Data Collection AF, via the Media Session Handler and 5GMS AF.
R3
This reference point is not instantiated in the 5GMS architecture.
R4
Media streaming access reporting by the 5GMS AS to the Data Collection AF.
R5
Event exposure by the Data Collection AF to subscribing NWDAF [23] instances.
R6
Event exposure by the Data Collection AF to subscribing Event Consumer AF instances in the 5GMS Application Provider.
R7
This reference point is not instantiated in the 5GMS architecture.
M6
Configuration of 5GMS-related data reporting by the 5GMS-Aware Application.
R8
This reference point is not instantiated in the 5GMS architecture.
4.7.2 UE data reporting for 5GMS p. 45
4.7.2.1 UE data reporting procedures for downlink media streaming p. 45
The following UE data reporting procedures are in scope for the instantiation of the abstract data collection and reporting architecture in the downlink 5GMS architecture:
- The procedures defined in clause 5.5 shall be used by the Direct Data Collection Client instantiated in the Media Session Handler to report QoE metrics for downlink media streaming to the Data Collection AF instantiated in the 5GMSd AF.
- The procedures defined in clause 5.6 shall be used by the Direct Data Collection Client instantiated in the Media Session Handler to report consumption of downlink media streaming to the Data Collection AF instantiated in the 5GMSd AF.
- Invocations of the downlink dynamic policy procedures defined in clause 5.8 shall be logged by the 5GMSd AF and reported to its subordinate Data Collection AF.
- Invocations of the AF-based downlink Network Assistance procedures defined in clause 5.9.2 shall be logged by the 5GMSd AF and reported to its subordinate Data Collection AF during active AF-based Network Assistance sessions.
- The procedures defined in clause 5.11.1 and 5.11.2 shall be used by the 5GMSd AS to report downlink media streaming access activity to the Data Collection AF instantiated in the 5GMSd AF via reference point R4.
- The procedures defined in clause 4.7.2.3 shall be used by the Direct Data Collection Client instantiated in the Media Session Handler to report invocations of the ANBR-based downlink Network Assistance procedures to the Data Collection AF instantiated in the 5GMSd AF via reference point R2.
4.7.2.2 UE data reporting procedures for uplink media streaming p. 46
The following UE data reporting procedures are in scope for the instantiation of the abstract data collection and reporting architecture in the uplink 5GMS architecture:
- Invocations of the AF-based uplink Network Assistance procedures defined in clause 6.5 shall be logged by the 5GMSu AF and reported to its subordinate Data Collection AF during active AF-based Network Assistance sessions.
- The procedures defined in clause 4.7.2.3 shall be used by the Direct Data Collection Client instantiated in the Media Session Handler to report invocations of the ANBR-based uplink Network Assistance procedures to the Data Collection AF instantiated in the 5GMSu AF via reference point R2. .
- The procedures defined in clause 6.8.1 and 6.8.2 shall be used by the 5GMSu AS to report uplink media streaming access activity to the Data Collection AF instantiated in the 5GMSu AF via reference point R4.
4.7.2.3 UE data reporting of ANBR-based Network Assistance invocations |R18| p. 46
Invocations of ANBR-based Network Assistance by the Media Session Handler for both downlink and uplink media streaming shall be reported by the Network Assistance subfunction of the Direct Data Collection Client to the Data Collection AF at reference point R2 according to the reporting requirements indicated in a data collection client configuration it has previously obtained at this reference point.
ANBR-based Network Assistance invocation reports shall contain the following parameters:
- Timestamp of the invocation.
- UE identification, e.g. the GPSI or current IP address.
- The DNN and S-NSSAI.
- UE location.
- Recommended bit rate.

The following restriction dimensions and aggregation functions defined in clause 4.5.2 of TS 26.531 may be provisioned in a Data Access Profile as part of a 5GMSd Provisioning Session and shall, as a consequence, be applied to reported UE data prior to exposing it to event consumers.
