Advanced Media Delivery (AMD) - In-band reporting of CMCD information

[dsilhavy]

General Description

26.804 - "Study on 5G media streaming extensions" is a technical report that identifies and evaluates a set of potential improvements and extensions for 5G Media Streaming. One of these identified extensions is Common Media Client Data (CMCD)

CMCD defines a set of media client data, structured as key/value pairs, that allows a media player to communicate
mutually beneficial media-related information to a CDN via either (i) a set of custom headers, (ii) a URL request query string, or (iii) a JSON object. Common is used because the same data structure can be used across all players and all CDNs.

Implementation Architecture

• The 5GMSd Application Provider provisions the CMCD reporting via reference point M1 of the 5GMSd Application Function
• The 5GMSd Application Function adds the CMCD configuration to the Service Access Information
• The 5GMSd Application Function configures the CMCD collection on the 5GMSd Application Server via reference point M3

Implementation

The concrete implementation tasks are created as sub-issues linking to this "container" issue.
