Multimedia subprotocols over real time protocol

A user equipment (UE) comprising:

• at least one memory that stores a communication application and at least one user interface application;
• and
• a at least one processor communicatively connected to the at least one memory and which is configured to cause the UE to:
• establish a real-time data exchange session with the payload communicating device;
• receive at least one subprotocol format that corresponds respectively to at least one of audiovisual media content and non-audiovisual content;
• receive real-time payload from the payload communication device functioning as a payload transmitting device;
• de-encapsulate real-time communication data from the real-time payload, using the at least one subprotocol format;
• and
• provide the real-time communication data to the at least one user interface application, which utilizes the real-time communication data comprising the at least one of the audiovisual media content and the non-audiovisual content.

A method for wireless communication at a user equipment (UE), the method comprising:

• executing at least one user interface application by a controller of a payload communicating device functioning as a payload transmitting device, which generates real-time communication data comprising at least one of audiovisual media content and non-audiovisual content;
• determining at least one subprotocol format of a real-time protocol that corresponds respectively to the at least one of the audiovisual media content and the non-audiovisual content;
• establishing a communication link for a real-time data exchange session with a payload receiving device;
• encapsulating the real-time communication data into real-time payload, using the at least one subprotocol format;
• and
• transmitting the real-time payload to a payload receiving device.

A network device comprising:

• at least one memory that stores a repository containing a plurality of uniform resource identifiers (URIs), whereby each URI corresponds to a resource description of a subprotocol format;
• and
• at least one processor communicatively connected to the at least one memory, and which:
• during establishment of a real-time data exchange session between the payload transmitting device and the payload receiving device, receives, via the transceiver from one of the payload transmitting device and the payload receiving device, a request for a respective uniform resource identifier (URI) for at least one real-time subprotocol format corresponding to at least one of audiovisual media content and non-audiovisual content;
• accesses, using the URI, the at least one real-time subprotocol format in the repository;
• and
• transmits the at least one real-time subprotocol format to at least one of the payload transmitting device and the payload receiving device, wherein the at least one real-time subprotocol format comprises a respective resource description that enables encapsulating and de-encapsulating of real-time payload.
