A communication to support Aircraft-to-Everything (A2X) services leveraging PC5 and/or Uu reference points. A2X services are realized by various types of A2X applications.

A dedicated messaging type of A2X service.

A data service, offered to A2X applications and optionally A2X Application Servers. An A2X service belongs to one A2X service type. An A2X service can be associated with one or more A2X applications, and a A2X application can be associated with one or more A2X services.

A type of A2X service, which is identified by any one of ITS-AID (ITS Application Identifier), PSID (Provider Service Identifier) or AID (Application Identifier) according to values defined specifically for aviation applications.

An identifier identifying an entity, e.g. a UAV, a UAV-C, within the context of a specific A2X application. These identifiers are used for Direct C2 Communication or for Direct Detect And Avoid. The format of this identifier is outside the scope of 3GPP.

A ground-based entity that is responsible for managing the airspace for a specific area/arena so that correspondingly residing UAVs are prevented to collide with each other and with other physical objects. For this purpose, AAM is able to detect UAVs residing in the specific airspace and provide policies for collision avoidance to the corresponding UASs. The AAM acts as a TPAE having specific abilities for direct communication with UAVs relevant for the applicable airspace and it includes one or more UEs enabled for use of PC5.

The capability of providing Remote Identification and Tracking over broadcast radio links.

a UAV identity assigned by USS/UTM, and uniquely identifies a UAV at least within the scope of a USS.

the user plane link to deliver messages with information of command and control for UAV operation from a UAV controller or a UTM to a UAV or to report telemetry data from a UAV to its UAV controller or a UTM. C2 communication may be over Uu reference point or PC5 reference point.

Contains application layer information sent by the UAS to the USS containing UAV pairing information and/or flight authorization information that is transparent to the 3GPP System.

Contains application layer information sent by the USS to the UAV containing e.g. C2 pairing information and/or C2 security information that is transparent to the 3GPP System.

Contains UAV-C Addressing Information which may e.g. include the UAV-C IP Address.

The capability to see, sense or detect conflicting traffic or other hazards and take the appropriate action.

DAA that leverages communications over PC5 reference point.

the UAV controller and UAV establish a direct C2 link over PC5 reference point to communicate with each other.

a UAV Controller connected to the 3GPP network and connected to the UAV via a 3GPP network.

a UAV Controller not connected to the 3GPP network and connected to UAV via a transport outside the scope of 3GPP, e.g. internet connectivity or direct wireless communication over a technology outside the scope of 3GPP.

The capability of providing Remote Identification and Tracking to a USS over 3GPP network.

The ability of a UAS in flight to provide identification and tracking information that can be received by other parties, to facilitate advanced operations for the UAS (such as Beyond Visual Line of Sight operations as well as operations over people), assist regulatory agencies, air traffic management agencies, law enforcement, and security agencies when a UAS appears to be flying in an unsafe manner or where the UAS is not allowed to fly. The Remote ID information payload may include Serial Number or Session ID assigned to the UAV, location of the ground-station controller, emergency status indication, etc.

is either a privileged Networked UAV Controller, or a privileged Non-Networked UAV Controller, or another entity which gets information on sets of UAV controllers and UAVs from the 3GPP network, and may be connected to the UAV via the Internet; it may be authorized by the UTM to interface with sets of UAV(s).

a 3GPP UAS Network Function for support of aerial functionality related to UAV identification, authentication/authorization and tracking, and to support Remote Identification.

An entity that provides services to support the safe and efficient use of airspace by providing services to the operator / pilot of a UAS in meeting UTM operational requirements. A USS can provide any subset of functionality to meet the provider's business objectives (e.g. UTM, Remote Identification). In the scope of this specification, the term USS refers to both USS and USS/UTM.

a system that can safely and efficiently integrate the flying UAV along with other airspace users. It provides a set of functions and services for managing a range of autonomous vehicle operations (e.g. authenticating UAV, authorizing UAS services, managing UAS policies, and controlling UAV traffics in the airspace).

The UAV controller of a UAS enables a drone pilot to control an UAV.

the entity owning and operating a UAV.

A container to the 3GPP system that includes UUAA Aviation/Authorization Payload and/or C2 Aviation/Authorization Payload. The internal content of the individual payloads is transparent to the 3GPP system.

refers to establishment of connectivity for a UAS for communication with USS, for C2, for remote identification, and for UAV location and tracking.

A communication between a UAV and a USS other than C2 communication, by means of user plane data transmission for some UAS Services.

Contains application layer information optionally including UUAA result for UAV consumption provided by the USS to the UAS which is transparent to the 3GPP System.

Contains application layer information provided by the UAS to USS and is transparent to the 3GPP System

Composed of Uncrewed Aerial Vehicle (UAV) and related functionality, including command and control (C2) links between the UAV and the control station, the UAV and the network, and for remote identification. An UAS may comprise of a UAV and a UAV controller.

A list of the UAVs to be identified in the target area and served by the PLMN as the result of the UAV tracking requested by USS/UTM.

UAV USS authentication and authorization procedure of the UAV to ensure that the UAV has successfully registered with a USS and has therefore been authorized for operations by the USS. An UAV is authenticated and authorized by USS via a UUAA procedure with the support of the 3GPP system before connectivity for UAS services is enabled.

the UUAA procedure optionally performed during registration to a 5GS.

the UUAA procedure performed during the establishment of a PDU session and performed during the establishment of a PDN connection.
