## Abstract

The present disclosure relates to a UAV service supporting method and device. The UAV service supporting method includes: receiving an attach request signaling sent by user equipment (UE) through a base station, the attach request signaling including UAV capability indication information, the UAV capability indication information being used to indicate whether the UE has a UAV capability; determining a UAV service authorization status of the UE based on the UAV capability indication information; and transmitting an initial context setup request signaling to the base station, the initial context setup request signaling including a UAV authorization signaling used for indicating the UAV service authorization state of the UE. By means of the disclosed technical solution, a core network device may indicate a UAV service authorization state of UE to a base station, thereby helping the base station to determine whether the UE is authorized to perform the UAV service, and when the UE is authorized to perform the UAV service, the UAV provides a UAV-related service.

## Claims

### Claim 1

A method for supporting an unmanned aerial vehicle (UAV) service, applied to a core network device, the method comprising:
receiving an attach request signaling that is transmitted by user equipment (UE) through a base station, the attach request signaling comprising UAV capability indication information, the UAV capability indication information being configured to indicate whether the UE has a UAV capability;
determining a UAV service authorization state of the UE based on the UAV capability indication information; and
transmitting an initial context setup request signaling to the base station, the initial context setup request signaling comprising a UAV authorization signaling configured to indicate the UAV service authorization state of the UE.

### Claim 2 (depends on 1)

The method of claim 1, further comprising:
in response to a change in the UAV service authorization state of the UE, transmitting a UE context modification request signaling to the base station, the UE context modification request signaling comprising the UAV authorization signaling configured to indicate the UAV service authorization state of the UE.

### Claim 3 (depends on 1)

The method of claim 1, wherein determining the UAV service authorization state of the UE comprises:
transmitting an enquiry message for obtaining the UAV service authorization state of the UE to a Home Subscriber Server (HSS), the enquiry message comprising identification information of the UE; and
receiving the UAV service authorization state of the UE returned by the HSS.

### Claim 4 (depends on 1)

The method of claim 1, wherein transmitting the initial context setup request signaling to the base station comprises:
in response to that the UAV service authorization state of the UE is an unauthorized state, setting a type of the UAV authorization signaling as an unauthorized type, and
transmitting the initial context setup request signaling to the base station, the initial context setup request signaling comprising the UAV authorization signaling configured to indicate that the UAV service authorization state of the UE is the unauthorized state; and
in response to that the UAV service authorization state of the UE is an authorized state, setting the type of the UAV authorization signaling as an authorized type, and
transmitting the initial context setup request signaling to the base station, the initial context setup request signaling comprising the UAV authorization signaling configured to indicate that the UAV service authorization state of the UE is the authorized state.

### Claim 5

A method for supporting an unmanned aerial vehicle (UAV) service, applied to user equipment (UE), the method comprising:
performing a random access operation based on a random access procedure; and
transmitting an attach request signaling to a core network device through a base station after accessing the base station successfully, the attach request signaling comprising UAV capability indication information configured to indicate whether the UE has a UAV capability.

### Claim 6

A method for supporting an unmanned aerial vehicle (UAV) service, applied to a base station, the method comprising:
receiving an initial context setup request signaling from a core network device, the initial context setup request signaling comprising a UAV authorization signaling configured to indicate a UAV service authorization state of user equipment (UE);
in response to that the UAV service authorization state is an authorized state, providing a UAV association service to the UE; and
in response to that the UAV service authorization state is an unauthorized state, refusing to provide the UAV association service to the UE.

### Claim 7 (depends on 6)

The method of claim 6, further comprising:
receiving a UE context modification request signaling from the core network device, the UE context modification request signaling comprising the UAV authorization signaling configured to indicate the UAV service authorization state of the UE;
determining a changed UAV service authorization state of the UE based on the UAV authorization signaling in the UE context modification request signaling;
in response to that the changed UAV service authorization state is the unauthorized state, stopping providing a UAV association service to the UE; and
in response to that the changed UAV service authorization state is the authorized state, providing the UAV association service to the UE.

### Claim at position 8

-14. (canceled)
