## Abstract

A flight reporting method can be performed by a reporting party, the reporting party including an unmanned aerial vehicle and/or unmanned aerial vehicle controller, the method including: determining flight reporting information, the flight reporting information including a first flight task to be reported; sending the flight reporting information to an unmanned aircraft system traffic management UTM device through a cellular network so that the UTM device can review the first flight task to obtain a review result; receiving the review result returned by the UTM device through the cellular network, the review result including review pass or review fail; according to the review result, determining whether to perform the first flight task.

## Claims

### Claim 1

A flight declaration method, comprising:
a declaration party determining flight declaration information, the declaration party comprising at least one of an unmanned aerial vehicle and an unmanned aerial vehicle controller, and the flight declaration information comprising a first flight mission to be declared;
the declaration party determining first signaling for carrying the flight declaration information, adding the flight declaration information to the first signaling, and sending the first signaling to a base station;
the base station obtaining the flight declaration information from the first signaling, and sending the flight declaration information to a core network device through a first interface, the first interface being an NG interface;
the core network device forwarding the flight declaration information to an unmanned aerial vehicle traffic management (UTM) device;
the UTM device reviewing the first flight mission to obtain a review result and sending the review result to the core network device, the review result comprising review passing or review failing;
the core network device sending the review result to the base station;
the base station receiving the review result sent by the core network device through a second interface, determining second signaling for carrying the review result, adding the review result to the second signaling, and sending the second signaling to the declaration party, the second interface being the NG interface, the second signaling comprising at least one of media access control address control element (MAC CE) and physical layer signaling, and the at least one of the MAC CE and the physical layer signaling carrying the review result;
the declaration party receiving the second signaling sent by the base station, obtaining the review result from the second signaling, determining whether to perform the first flight mission according to the review result; and
when the declaration party does not receive the review result within a specified time duration, re-sending the flight declaration information to the base station, and abandoning declaration when a number of re-declarations exceeds a predetermined threshold,
wherein the declaration party determining the first signaling for carrying the flight declaration information comprises:
in response to the declaration party performing network attachment, determining attachment request signaling as the first signaling, the attachment request signaling carrying the flight declaration information; and
in response to the declaration party having completed the network attachment, determining first radio resource control (RRC) signaling as the first signaling, the first RRC signaling comprising UE assistance information signaling, the UE assistance information signaling carrying the flight declaration information.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the declaration party determining whether to perform the first flight mission according to the review result comprises:
in response to the review result being the review passing, determining to perform the first flight mission; and
in response to the review result being the review failing, determining not to perform the first flight mission.

### Claim 3

A fight declaration system, comprising:
a declaration party, configured to determine flight declaration information comprising a first flight mission to be declared, determine first signaling for carrying the flight declaration information, add the flight declaration information to the first signaling, send the first signaling to a base station, receive second signaling sent by the base station, obtain, from the second signaling, a review result of an unmanned aerial vehicle traffic management (UTM) device reviewing the first flight mission, determine whether to perform the first flight mission according to the review result, and when the declaration party does not receive the review result within a specified time duration, re-send the flight declaration information to the base station, and abandon declaration when a number of re-declarations exceeds a predetermined threshold;
the base station, configured to obtain the flight declaration information from the first signaling, send the flight declaration information to a core network device through a first interface, receive the review result sent by the core network device through a second interface, determine second signaling for carrying the review result, add the review result to the second signaling, and send the second signaling to the declaration party, the first interface being an NG interface, the second interface being the NG interface, the second signaling comprising at least one of media access control address control element (MAC CE) and physical layer signaling, and the at least one of the MAC CE and the physical layer signaling carrying the review result;
the core network device, configured to forwarding the flight declaration information to the UTM device, receive the review result returned by the UTM device, and send the review result to the base station; and
the UTM device, configured to review the first flight mission to obtain the review result and send the review result to the core network device, the review result comprising review passing or review failing,
wherein the declaration party comprises at least one of an unmanned aerial vehicle and an unmanned aerial vehicle controller, and
the declaration party, when being configured to determine the first signaling for carrying the flight declaration information, is specifically configured to:
in response to the declaration party performing network attachment, determine attachment request signaling as the first signaling, the attachment request signaling carrying the flight declaration information; and
in response to the declaration party having completed the network attachment, determine first radio resource control (RRC) signaling as the first signaling, the first RRC signaling comprising UE assistance information signaling, the UE assistance information signaling carrying the flight declaration information.

### Claim 4 (depends on 3)

The fight declaration system according to claim 3, wherein the declaration party, when being configured to determine whether to perform the first flight mission according to the review result, is specifically configured to:
in response to the review result being the review passing, determine to perform the first flight mission; and
in response to the review result being the review failing, determine not to perform the first flight mission.
