Feature: Media Streaming Data Reporting at reference point R4

[davidjwbbc]

Feature Description

As part of the data collection and exposure framework in 5GMS, the Application Server can report media stream access to the Data Collection AF subfunction of the 5GMS Application Function. This then allows the easy dissemination of media access logs from the Data Collection AF to interested parties as part of the 5G Media Streaming framework.

This work includes:

• Transfer of Data Collection AF URL via M3 from the 5GMS AF.
• Registration as a Data Collection Client with the DCAF via R4:
  • If configuration return from DCAF registration contains Media Streaming Access configuration:
    • Access data is collected and reports are sent, via R4, according to the configuration received.
