This procedure enables the configuration of the UAE client, based on a request from UAS application specific server to configure the DAA application policy to the UAE client.
Pre-conditions:
1. The UAS UEs are connected to 5GS and authenticated and authorized by UAS application specific server as specified in clause 5.2 of 3GPP TS 23.256 [4].
2. UAE server has established a UAE session with the respective UAE clients as the UAE clients are successfully registered to the UAE server.
3. UAE server has performed the DAA support management procedure according to clause 7.7.2.1.1.
Figure 7.7.2.1.2-1: DAA support configuration procedure
1. The UAE server shall send a DAA support configuration request to the UAE client. The UAE client receives a DAA support configuration request from the UAE server that includes the DAA application policy. If the UAE client has LDGS capability, and the procedure is for LDGS assisted DAA, then the DAA application policy includes parameters for the control of LDGS assisted DAA.
NOTE: The UAE client can serve multiple USSes, hence, the UAE client receives configuration information pertaining to each USS.
2. The UAE client shall store or remove the DAA application policy as per the information received in step 1. The DAA application policy is forwarded to the UAS application.
3. The UAE client shall send a DAA support configuration response to the UAE server. |

If the UAE client has LDGS capabilities, the UAE client provides ground based DAA assistance for the target UAVs in its monitoring range.
Pre-conditions:
1. UAE server has provided the DAA application policy to the UAE client.
2. The UAE client can communicate with the target UAVs using U2X communication.
Figure 7.7.2.2.1-1: DAA support involving UAVs with U2X support
1. The UAE layer has, e.g. based on information provided by the U2X layer, detected UAVs in proximity, see 3GPP TS 23.256 [4] clause 5.6. The UAE client informs its own UAS application specific server about the detected collision. If the UAE client has LDGS capability, and the procedure is for LDGS assisted DAA, then based on the configuration/policy received from the USSes (e.g., DAA triggering thresholds), the LDGS assists with deconfliction by detecting possible collisions.
2. The UAE client shall send a DAA client event information to the UAE server with information about one or more UAVs in proximity as detected or about a LDGS collision detection performed in step 1.
3. The UAE server shall record the DAA client event information with current timestamp. UAE server shall request UAE client location information from the SEAL location services. The UAE server shall record the received location information with current timestamp. The UAE server shall send the DAA client event information to the UAS application specific server.
4. The UAS application specific server provides a DAA client event information acknowledge to the UAE server. The UAS application specific server may include more information in the acknowledgement (e.g., other UAVs detected information by UAS application layer mechanisms, alternative flight path). If the event information indicates LDGS deconfliction assistance, the UAS application specific server sends DAA flightpath update to the LDGS.
5. The UAE server shall send a DAA client event information acknowledge to the UAE client, and the UAE client shall provide the application layer (i.e. UAS client) with the consolidated information from the UAS application specific server. If the UAE client has LDGS capability, and the procedure is for LDGS assisted DAA, then the LDGS assists with deconfliction by sending the flight path information to respective target UAVs using U2X connectivity. |

19da2a74570834d986caa9f57137c28d | 23.255 | 7.8 Tracking dynamic UAVs in an application defined area relative to a host UAV | |
19da2a74570834d986caa9f57137c28d | 23.255 | 7.8.1 General | The UAE server can be responsible for tracking a host UAV’s dynamic information (i.e., information of other dynamic UAVs in an application defined area relative to a host UAV). As per a proximity range set by the application layer (e.g. UAS Application Specific Server), the UAE layer supports providing the dynamic information (i.e. other UAVs’ location information) to the UAS Application Specific Server (UTM/USS) and/or to the host UAV. This feature can be utilized by UAS applications (e.g. DAA, Dynamic maps).
This feature utilizes the following procedures:
- UAS Application Specific Server or the host UAV subscription for host UAV’s dynamic information with UAE server.
- UAE server tracking host UAV’s UE location with support from SEAL’s location management server.
- UAE server management of dynamic UE location based group.
- UAE server obtaining dynamic information from the UAVs in application defined proximity range of the host UAV.
- UAE server notification of host UAV’s dynamic information to the UAS Application Specific Server and/or to the host UAV.
NOTE: The details of the usage of dynamic information of host UAV by UAS Application Specific Server or by the host UAV is out of scope of this specification. |

1. Dynamic UE location based group creation or update is triggered (e.g. notified of the UE location of host UAV) via the step 4 in clause 7.8.2.1 for the UAV ID of the host UAV.
2. UAE server 1 uses its associated LMS 1 to obtain the dynamic UE list and the corresponding location information in the proximity area of the host UAV by providing the application defined proximity range and the UE location of the host UAV as specified in clause 9.3.10 of 3GPP TS 23.434 [5].
3. UAE server 1 determines the list of other UAE servers 2..N operating in the same location.
4. For each UAE server determined in step 3, UAE server 1 requests the dynamic UE list and its corresponding location information for the application defined proximity range by providing the UE location of the host UAV.
5. The UAE server(s) 2..N obtain UE information corresponding to the UE location and application defined proximity range from its corresponding LMS 2..N as specified in 3GPP TS 23.434 [5].
6. The UAE server(s) 2..N sends get response with UE list in the UE location and application defined proximity range to UAE server 1.
7. If UAE server 1 has no dynamic UE location group for the UAV ID, the UAE server 1 creates a dynamic UE location based group with the UE list received from its LMS and other UAE server(s) 2..N. Further UAE server 1 stores the dynamic UE location based group. Otherwise, the UAE server 1 updates the dynamic UE location group with the latest UE information. The UAVs whose locations are no more within the application defined proximity range are removed from the dynamic UE location group. |

- UAV has performed the UAS UE registration procedure.
Figure 7.10.2.1-1: Flight route calculation procedure
1. The UAS application specific server or UAE client (UAV or UAV-C) sends flight route request towards the UAE server. This request contains network parameters needed for the specific needs of the specific use case (start point, destination point, specific times of start point and end point, needed QoS, link reliability, shortest route needed, etc).
2. The UAE server has the role of a route planning unit and based on the received end points and provisioned information (e.g., restricted areas, existing flight paths, available base stations coverage, shortest distance, shortest time duration) calculates possible waypoints as geographical coordinates and specific times.
3. The UAE server checks with NWDAF (via NEF) the QoS sustainability analytics (clause 6.9 of 3GPP TS 23.288 [15]) in these areas of interest/waypoints identified in step 2. Location information towards the NWDAF is presented as area of interest or path of interest and can reflect a list of waypoints. Based on the received information from NWDAF the UAE server selects waypoints (geographical coordinates and time) which KPIs map the requested criteria in step1.
4. The UAE server sends flight route reply with the selected waypoints in step 3 to the entity which has send the request (UTM, UAV or UAV-C). |
