Signaling usage of PDU set and end of burst marking for communicating WebRTC media data

A device for communicating media data, the device comprising:

• a memory configured to store media data;
• and
• a processing system comprising one or more processors implemented in circuitry, the processing system being configured to:
• receive a session description protocol (SDP) message including configuration information representing at least one of protocol data unit (PDU) set marking or end of burst (EoB) marking for a communication session during a startup phase of the communication session or a configuration update phase of the communication session, the startup phase or the configuration update phase being negotiated between devices participating in the communication session, the devices participating in the communication session including a user equipment (UE) and an application server or a remote UE, the device being separate from the UE and the application server or the remote UE;
• extract a header extension map attribute from the SDP message, the header extension map attribute linking a local identifier value to a uniform resource name (URN) corresponding to the at least one of the PDU set marking or the EoB marking;
• determine a format for the PDU set marking or the EoB marking according to the header extension map attribute;
• send information representing the PDU set marking or the EoB marking for the communication session to a media application function;
• and
• process a packet including media data of the communication session, the packet including a header extension including the local identifier value and the at least one of the PDU set marking or the EoB marking according to the header extension map attribute.
