22.1253GPPTSUnmanned Aerial System (UAS) support in 3GPP
Beyond UAV related requirements, the 3GPP can be used to support for a wide range of applications and scenarios by using low altitude UAVs in various commercial and government sectors. New service level requirements and KPIs for supporting various UAV applications by the 3GPP system have been identified and specified e.g. Service requirements and KPIs related to command and control (C2), payload (e.g. camera) and the operation of radio access nodes on-board UAVs.
6.2 Network exposure for UAV services
The 3GPP system shall provide means to allow a 3rd party to request and obtain real-time monitoring the status information (e.g., location of UAV, communication link status) of a UAV.
Based on operator ‘s policy, the 3GPP system shall provide means to provide a 3rd party with the information regarding the service status for UAVs in a certain geographical area and/or at a certain time.
NOTE: Service status is about the information of whether the communication service to the UAV can be provided with a certain QoS by the network.
6.3 Service restriction for UEs onboard of UAV
The 3GPP network shall be able to support network-based 3D space positioning (e.g., with altitude 30~300m) of a UE onboard UAV.
The 3GPP system shall be able to notify the authorized third party of potential stopping of connectivity service before the UE onboard of UAV enters an area (e.g., due to altitude) where the connectivity service is not authorized for the UE.
6.4 Requirements for UxNB
The 5G system shall be able to support UxNBs to provide enhanced and more flexible radio coverage.
The 3GPP system shall be able to provide suitable means to control the operation of the UxNBs (e.g. to start operation, stop operation, replace UxNB etc.).
The 3GPP system shall be able to provide means to minimize power consumption of the UxNBs (e.g. optimizing operation parameter, optimized traffic delivery).
The 3GPP system shall able to minimize interference e.g. caused by UxNBs changing their postions.
6.5 C2 communication
The 3GPP system shall support C2 communication with required QoS for pre-defined C2 communication models (e.g. using direct ProSe Communication between UAV and the UAV controller, UTM-navigated C2 communication based on flight plan between UTM and the UAV).
The 3GPP system shall support C2 communication with required QoS when switching between the C2 communication models.
The 3GPP system shall support a mechanism for the UTM to request monitoring of the C2 communication with required QoS for pre-defined C2 communication models (e.g. using direct ProSe Communication between UAV and the UAV controller, UTM-navigated C2 communication between UTM and the UAV).
