Metrics collection and reporting in 5G media streaming

A method for supporting metrics measurement, collection and reporting for Fifth Generation (5G) Media Streaming service performed by a Media Session Handler running on a processor of a wireless device connected to a radio access network (RAN) of a 5G system (5GS) network, comprising:

• receiving a metrics configuration message from an application function (AF) server of the 5GS network via an application layer control plane based M5 interface, wherein the metrics configuration message includes a plurality of metrics scheme parameters including a first metrics scheme parameter identified by a first uniform resource identifier (URI) and a second metrics scheme parameter identified by a second URI different than the first URI, the first metrics scheme parameter representing a first metrics scheme and the second metrics scheme parameter representing a second metrics scheme different than the first metrics scheme, the first metrics scheme defining first metrics measurement, collection, and reporting requirements for a first list of metrics associated with the first metrics scheme, and the second metrics scheme defining second metrics measurement, collection, and reporting requirements for a second list of metrics associated with the second metrics scheme;
• establishing a media session for the 5G Media Streaming service with the AF server, the media session including media data originating from an application provider;
• determining the first list of metrics and the second list of metrics to be collected for the media data of the media session based at least in part on the first metrics scheme parameter representing the first metrics scheme and the second metrics scheme parameter representing the second metrics scheme;
• querying a Media Player of the wireless device to determine whether the Media Player has a capability to measure and log the first list of metrics associated with the first metrics scheme and the second list of metrics associated with the second metrics scheme;
• determining that the Media Player has the capability to measure and log the first list of metrics and the second list of metrics;
• starting media playback of the media data of the media session;
• collecting first metrics associated with the first list of metrics and second metrics associated with the second list of metrics for the media data from the Media Player after the start of the media playback;
• based on the collected first metrics according to the first metrics scheme, generating a first metrics report associated with the media playback of the media data;
• based on the collected second metrics according to the second metrics scheme, generating a second metrics report associated with the media of the media data;
• and
• sending the first metrics report and the second metrics report associated with the media playback to the AF server via the application layer control plane based M5 interface.

An application function (AF) server of a Fifth Generation (5G) system (5GS) network, comprising:

• a processor configured with processor-executable instructions to perform operations to:
• send a metrics configuration message to a wireless device via a control plane based M5 interface included in the 5GS network, wherein the metrics configuration message includes a plurality of metrics scheme parameters including a first metrics scheme parameter identified by a first uniform resource identifier (URI) and a second metrics scheme parameter identified by a second URI different than the first URI, the first metrics scheme parameter representing a first metrics scheme and the second metrics scheme parameter representing a second metrics scheme different than the first metrics scheme, the first metrics scheme defining first metrics measurement, collection, and reporting requirements for a first list of metrics associated with the first metrics scheme, and the second metrics scheme defining second metrics measurement, collection, and reporting requirements for a second list of metrics associated with the second metrics scheme;
• establish a media session for a 5G Media Streaming service with the wireless device, the media session including media data originating from an application provider;
• and
• receive a first metrics report corresponding to the first metrics scheme and a second metrics report corresponding to the second metrics scheme from the wireless device via the control plane based M5 interface, the second metrics report being different than the first metrics report, and the first metrics report and the second metrics report each being associated with the media data originating from the application provider, wherein the first metrics report includes collected metrics for the media data originating from the application provider associated with the first list of metrics, and the second metrics report includes collected metrics for the media data originating from the application provider associated with the second list of metrics.
