Systems and methods for secure and reliable command and control of in-flight uncrewed aerial vehicles via public land mobile networks
Systems and methods for supporting multiple uncrewed aerial vehicle (UAV) Service Suppliers (multi-USS) are described. The methods may be performed by a wireless transmit/receive unit (WTRU) including a UAV application enabling (UAE) client located in the UAV with the method performed with the UAV in-flight. Steps may include: sending a registration request to a UAE server, the registration request including an indication of multi-USS capability; receiving a registration response message that includes an indication that the UAE server supports multi-USS capability; receiving a multi-USS configuration request that includes multi-USS configuration parameters related to conditions under which the UAE client may initiate a USS change and a list of allowed USSs; sending a multi-USS configuration response; and performing a multi-USS change and sending a multi-USS change notification based on the multi-USS configuration parameters.
1. A method performed by a wireless transmit/receive unit (WTRU) including a UAV application enabling (UAE) client in an in-flight uncrewed aerial vehicle (UAV) for supporting multiple UAV system (UAS) Service Suppliers (multi-USS), the method comprising:
sending a registration request to a UAE server, the registration request including an indication of multi-USS capability;
receiving a registration response message;
receiving a multi-USS configuration request that includes a multi-USS policy comprising an allowed USS;
sending a multi-USS configuration response;
performing a USS change; and
sending a change notification based on the multi-USS policy, including a cause for change of USS.
2. The method of claim 1 , wherein the USS change notification is further based on receiving a USS change request from a UAE server.
3. The method of claim 1 , wherein the multi-USS configuration request is a request to delete a first USS configuration and the method further comprises removing the first USS configuration if the request to delete is associated with a USS that matches a USS associated with the UAE.
4. The method of claim 3 , wherein the USS associated with the UAE holds a subscription for the UAV.
5. The method of claim 3 , wherein the USS associated with the UAE previously authenticated and authorized the UAV.
6. The method of claim 1 , wherein the multi-USS configuration request is a request to add a second USS configuration and the method further comprises storing the second USS configuration.
7. The method of claim 1 , wherein the multi-USS policy includes a rule for initiating a USS change wherein only a first USS can initiate a change.
8. The method of claim 1 , wherein the multi-USS policy includes a rule allowing any allowed USS to initiate a USS change when a connection is lost with a first USS.
9. The method of claim 1 , wherein the conditions under which the UAE client initiates a USS change include the UAE client moving from a first geographic area associated with a first USS to a second geographic area associated with a second USS.
10. The method of claim 1 , wherein the multi-USS policy further comprises a geographical area in which the allowed USS is active.
11. An uncrewed aerial vehicle (UAV), comprising:
a wireless transmit/receive unit (WTRU) including a UAV application enabling (UAE) client for supporting multiple UAV system (UAS) Service Suppliers (multi-USS), the WTRU configured to:
send a registration request to a UAE server, the registration request including an indication of multi-USS capability;
receive a registration response message;
receive a multi-USS configuration request that includes multi-USS policy comprising an allowed USS;
send a multi-USS configuration response;
perform a USS change; and
send a USS change notification based on the multi-USS policy, including a cause for change of USS.
12. The UAV of claim 11 , wherein the USS change notification is further based on receiving a USS change request from a UAE server.
13. The UAV of claim 11 , wherein the multi-USS configuration request is a request to delete a first USS configuration and the the WTRU is further configured to remove the first USS configuration if the request to delete is associated with a USS that matches a USS associated with the UAE.
14. The UAV of claim 13 , wherein the USS associated with the UAE holds a subscription for the UAV.
15. The UAV of claim 13 , wherein the USS associated with the UAE previously authenticated and authorized the UAV.
16. The UAV of claim 11 , wherein the WTRU is further configured to initiate communication based on the USS change.
17. The UAV of claim 11 , wherein the multi-USS policy includes a rule for initiating a USS change wherein only a first USS can initiate a change.
18. The UAV of claim 11 , wherein the multi-USS policy includes a rule allowing any allowed USS to initiate a USS change when a connection is lost with a first USS.
19. The UAV of claim 11 wherein the conditions under which the UAE client initiates a USS change include the UAE client moving from a first geographic area associated with a first USS to a second geographic area associated with a second USS.
20. The UAV of claim 11 , wherein the multi-USS policy further comprises a geographical area in which the allowed USS is active.
