Method and apparatus for performing authorization for unmanned aerial system service in wireless communication system

1. A method performed by an access and mobility management function (AMF) entity in a wireless communication system, the method comprising:

receiving, from a user equipment (UE), a registration request message including an identification (ID) of an unmanned aerial vehicle (UAV), the UE being the UAV or an UAV controller (UAVC) related to the UAV;

receiving, from an unified data management (UDM) a subscription data of the UE;

performing an authentication for the UAV; and

determining whether an unmanned aircraft system (UAS) traffic management (UTM) service supplier (USS) UAV authorization/authentication mobility management (UUAA-MM) for the UAV is required in case that the UE has a valid aerial subscription information, or the UE has provided the ID of the UAV.

2. A method performed by an unmanned aerial system-network function (UAS-NF) entity in a wireless communication system, the method comprising:

receiving, from an access and mobility management function (AMF) entity, an authentication request message including a generic public subscription identifier (GPSI) and unmanned aerial vehicle (UAV) identification (ID); and

transmitting, to an unmanned aircraft systems traffic management (UTM) entity, the authentication request message including the GPSI and UAV ID.

3. The method of claim 2 , wherein the authentication request message further includes user location information.

4. The method of claim 3 , wherein the user location information is cell ID.

5. A method performed by an authorization for a network exposure function (NEF) entity in a wireless communication system, the method comprising:

receiving, from a session management function (SMF) an authentication request message including service level information; and

transmitting, to an unmanned aerial system (UAS) entity, the authentication request message.

6. The method of claim 5 , wherein the service level information is an unmanned aerial vehicle (UAV) identification (ID) of an UAV.

7. A method performed by an authorization for a session management function (SMF) entity in a wireless communication system, the method comprising:

receiving, from an unmanned aerial vehicle (UAV), an authentication request message including an UAV ID and information related to a command and control (C2) communication;

performing an authentication procedure for an unmanned aircraft systems traffic management (UTM) entity and the UAV; and

receiving, from the UTM entity, authorization information for the C2 communication including an IP address of a UAV controller (UAVC).

8. The method of claim 7 , wherein the information related to the C2 communication includes flight authorization information.

9. The method of claim 7 , wherein the authentication request message further includes unmanned aerial system (UAS) information,

wherein the UAS information includes a cell ID indicating a location of the UAV.

10. A method performed by a session management function (SMF) entity in a wireless communication system, the method comprising:

receiving, from a terminal, a request message for a command and control (C2) communication including an unmanned aerial vehicle (UAV) identification (ID);

transmitting, to an unmanned aircraft systems traffic management (UTM) entity, an authentication request message including an address of an UAV; and

receiving, from the UTM entity, authorization information for the C2 communication including an IP address of an UAV controller (UAVC).

11. The method of claim 10 , wherein the UAV address is an IP address of the UAV.

12. The method of claim 10 , wherein the authorization information further includes location information of the UAV,

wherein the location information of the UAV is a cell ID.
