Abstract: In a method of group creation for a pair of an unmanned aerial vehicle (UAV) and an unmanned aerial vehicle-controller (UAV-C) in a service enabler architecture layer (SEAL) architecture, the pair of UAV and UAV-C is determined by an unmanned aerial system application enabler (UAE) server in the SEAL architecture. A group creation request for the pair of UAV and UAV-C is transmitted by the UAE server to a SEAL group management (GM) server of the SEAL architecture. A first response message is received by the UAE server from the SEAL GM server for the group creation request. A group including the pair of the UAV and the UAV-C is created for quality-of-service (QoS) management. The group creation request includes an identity of an UAE client corresponding to the pair of UAV and UAV-C, an identity of the UAV, and an identity of the UAV-C.

Abstract: Systems, methods, and devices for managing media storage and delivery, including obtaining, by a media access function (MAF), a Graphics Language Transmission Format (glTF) file corresponding to a scene; obtaining from the glTF file a uniform resource locator (URL) parameter indicating a binary data blob; determining that the binary data blob has a Concise Binary Object Representation (CBOR) format; converting the binary data blob into an object having a JavaScript Object Notation (JSON) format using a CBOR parser function implemented by the MAF; and obtaining media content corresponding to the scene based on the object.

Abstract: Systems and method may provide unmanned aerial vehicle (UAV) connection monitoring and location reporting. A method implemented by at least one processor includes receiving a location report indicating a location of the UAV from a first server; receiving a lost connection report indicating a loss of connection with the UAV; receiving a connection resumption report indicating that the connection with the UAV has been re-established; and based on receiving the connection resumption report, transmitting a location update request to the first server.

Abstract: A method, computer program, and computer system for enabling peer-to-peer media streaming using service enabler architecture layer (SEAL). The method may be executed by one or more processors, and the method may include receiving, by a vertical application layer (VAL) server, a request for a media session negotiation between one or more client devices, and retrieving, by the vertical application layer (VAL) server, transport layer information associated with each of the one or more client devices using network address translation traversal. The method may further include transmitting, by the vertical application layer (VAL) server, agreed session description protocol (SDP) parameters based on the transport layer information, wherein the agreed session description protocol (SDP) parameters are used to establish a peer-to-peer media streaming session.

Abstract: Systems and method may provide unmanned aerial vehicle (UAV) connection monitoring and location reporting. A method implemented by at least one processor includes receiving, by an unmanned aerial system application enabler (UAE) server, a location report indicating a location of the UAV from a location management (LM) server; receiving, by the UAE server, a lost connection report indicating a loss of connection with the UAV; receiving, by the UAE server, a connection resumption report from a network resource management (NRM) server indicating that the connection with the UAV has been re-established; and based on receiving the connection resumption report, transmitting, from the UAE server, a location update request to the LM server.

Abstract: A method, computer program, and computer system is provided for splitting viewport bitstreams. A first coded video bitstream is at least partially encoded using a first Group-of-Pictures (GOP) structure at a first resolution. A second coded video bitstream structured into a plurality of tiles is encoded using a second GOP structure at a second resolution, whereby the second GOP structure includes fewer coded pictures than the first GOP structure. A streaming bitstream for decoding or rendering is created using the first coded video bitstream and the second coded bitstream.

Abstract: Aspects of the disclosure provide methods and apparatus for accessing a Constrained Application Protocol (CoAP) server in a media scene description system. A CoAP request can be sent, by a media access function (MAF) of processing circuitry implementing the media scene description system using an application programming interface (API), to the CoAP server to request a media resource. The MAF can be configured as a CoAP client or a Hypertext Transfer Protocol (HTTP)-CoAP proxy. A CoAP response can be received, by the MAF using the API, from the CoAP server. In an example, the CoAP response includes the requested media resource. In an embodiment, the MAF is compatible with both the CoAP request according to a CoAP communication protocol and a proxy request according to an HTTP communication protocol.
