Abstract

The disclosure relates to a 5 th generation (5G) or 6 th generation (6G) communication system for supporting a higher data transmission rate. A method performed by an unmanned aerial system network function (UAS NF) in a wireless communication system providing a UAS service for an unmanned aerial vehicle user equipment (UAV UE) is provided. The method includes receiving, from a UAS service supplier (USS), a first message including information on a UAV USS authentication and authorization (UUAA) revocation for the UAV UE, identifying UUAA information for the UAV UE, determining, based on the UUAA information, a network entity to which the information on the UUAA revocation for the UAV UE is to be notified, and transmitting, to the network entity, a second message including the information associated with the UUAA revocation for the UAV UE.

First claim

What is claimed is:

1. A method performed by an unmanned aerial system network function (UAS NF) in a wireless communication system providing a UAS service for an unmanned aerial vehicle user equipment (UAV UE), the method comprising:
receiving, from a UAS service supplier (USS), a first message including notification for USS UAV authentication and authorization (UUAA) revocation associated with the UAV UE;
identifying UUAA information for the UAV UE;
determining, based on the UUAA information, a network entity to which the notification for the UUAA revocation associated with the UAV UE is to be transmitted;
transmitting, to the network entity, a second message including the notification for the UUAA revocation associated with the UAV UE;
receiving, from the network entity, a third message in response to the second message wherein the third message is related to removal of a successful UUAA result in the network entity; and
removing the UUAA information for the UAV UE in response to the third message.

2. The method of claim 1 , wherein the notification for the UUAA revocation includes cause information of the UUAA revocation for the UAV UE.

3. The method of claim 1 , further comprising storing the UUAA information for the UAV UE after a successful UUAA procedure for the UAV UE, the UUAA information including a UUAA context for the UAV UE.

4. The method of claim 1 , wherein the first message further includes at least one of generic public subscription identifier (GPSI), civil aviation administration (CAA)-Level UAV ID, or a protocol data unit (PDU) session internet protocol (IP) address for the UAV UE.

5. The method of claim 1 , further comprising:
transmitting, to the USS, a response message indicating an authorization revocation for the UAV UE.

6. The method of claim 1 , wherein the network entity is either an access and mobility management function (AMF) performing a UUAA-mobility management (MM) procedure for the UAV UE or a session management function (SMF) performing a UUAA-session management (SM) procedure.

7. The method of claim 6 , further comprising:
receiving, from the AMF or the SMF, a fourth message including information indicating a change of aerial subscription information for the UAV UE; and
transmitting, to the USS, a fifth message including information notifying the change to the USS in case that the aerial subscription information is changed from ‘authorized’ to ‘no authorized’.

8. An unmanned aerial system network function (UAS NF) in a wireless communication system providing a UAS service for an unmanned aerial vehicle user equipment (UAV UE), the UAS NF comprising:
a transceiver; and
at least one processor coupled to the transceiver and configured to:
receive, from a UAS service supplier (USS), a first message including notification for USS UAV authentication and authorization (UUAA) revocation associated with the UAV UE,
identify UUAA information for the UAV UE,
determine, based on the UUAA information, a network entity to which the notification for the UUAA revocation associated with the UAV UE is to be transmitted,
transmit, to the network entity, a second message including the notification for the UUAA revocation associated with the UAV UE,
receive, from the network entity, a third message in response to the second message wherein the third message is related to removal of a successful UUAA result in the network entity, and
remove, the UUAA information for the UAV UE.

9. The UAS NF of claim 8 , wherein the notification for the UUAA revocation includes cause information of the UUAA revocation for the UAV UE.

10. The UAS NF of claim 8 , wherein the at least one processor is further configured to store the UUAA information for the UAV UE after a successful UUAA procedure for the UAV UE, the UUAA information including a UUAA context for the UAV UE.

11. The UAS NF of claim 8 , wherein the first message further includes at least one of generic public subscription identifier (GPSI), civil aviation administration (CAA)-Level UAV ID, or a protocol data unit (PDU) session internet protocol (IP) address for the UAV UE.

12. The UAS NF of claim 8 , wherein the at least one processor is further configured to transmit, to the USS, a response message indicating an authorization revocation for the UAV UE.

13. The UAS NF of claim 8 , wherein the network entity is either an access and mobility management function (AMF) performing a UUAA-mobility management (MM) procedure for the UAV UE or a session management function (SMF) performing a UUAA-session management (SM) procedure.

14. The UAS NF of claim 13 , wherein the at least one processor is further configured to:
receive, from the AMF or the SMF, a third message including information indicating a change of aerial subscription information for the UAV UE, and
transmit, to the USS, a fourth message including information notifying the change to the USS in case that the aerial subscription information is changed from ‘authorized’ to ‘no authorized’.

15. An access and mobility management function (AMF) in a wireless communication system providing an unmanned aerial system (UAS) service for an unmanned aerial vehicle user equipment (UAV UE), the AMF comprising:
a transceiver; and
at least one processor configured to:
perform a UAS service supplier UAV (USS UAV) authentication and authorization-mobility management (UUAA-MM) procedure for the UAV UE,
receive, from a unified data management (UDM) managing aerial subscription information, a first message for indicating a change of the aerial subscription information for the UAV UE, and
transmit, to a UAS network function (UAS NF), a fourth message for indicating the change of the aerial subscription information for the UAV UE.

16. The AMF of claim 15 , wherein the change of the aerial subscription information includes that the aerial subscription information for the UAV UE is changed from ‘authorized’ to ‘no authorized’.

17. The AMF of claim 15 , wherein the at least one processor is further configured to receive, from the UAS NF, a second message including notification for a UUAA revocation associated with the UAV UE, wherein the notification for the UUAA revocation includes cause information of the UUAA revocation for the UAV UE.

18. A session management function (SMF) in a wireless communication system providing an unmanned aerial system (UAS) service for an unmanned aerial vehicle user equipment (UAV UE), the SMF comprising:
a transceiver; and
at least one processor configured to:
perform a UAS service supplier UAV (USS UAV) authentication and authorization-session management (SM) procedure for the UAV UE,
receive, from a unified data management (UDM) managing aerial subscription information, a first message for indicating a change of the aerial subscription information for the UAV UE, and
transmit, to a UAS network function (UAS NF), a fourth message for indicating the change of the aerial subscription information for the UAV UE.

19. The SMF of claim 18 , wherein the change of the aerial subscription information includes that the aerial subscription information for the UAV UE is changed from ‘authorized’ to ‘no authorized’.

20. The SMF of claim 18 , wherein the at least one processor is further configured to receive, from the UAS NF, a second message including notification for a UUAA revocation associated with the UAV UE, wherein the notification for the UUAA revocation includes cause information of the UUAA revocation for the UAV UE.
