After the access network device obtains the flight path information of the UAV, the access network device can send the paging signaling carrying the flight path information of the UAV to other access network devices, in order to instruct other access network devices to page the UAV and provide the flight path information to the UAV. ## Claims ### Claim 1 A method for providing a UAV flight path, comprising: receiving, by a first access network device, flight path information of a UAV in an inactive state; and sending, by the first access network device, a paging signaling carrying the flight path information of the UAV to a second access network device, the paging signaling being configured to instruct the second access network device to page the UAV and provide the flight path information to the UAV. ### Claim 2 (depends on 1) The method of claim 1, wherein 1, receiving the flight path information of the UAV in the inactive state, further comprises receiving the flight path information of the UAV from: a UAV management system, or a core network device. ### Claim 3 (depends on 1) The method of claim 1, wherein sending the paging signaling carrying the flight path information of the UAV to the second access network device, further comprises: sending the paging signaling to the second access network device in a RAN Notification Area (RNA) where the UAV is located. ### Claim 4 (depends on 1) The method of claim 1, further comprising: sending, by the first access network device, a paging message configured to page the UAV. ### Claim 5 (depends on 4) The method of claim 4, wherein the paging message comprises the flight path information of the UAV. ### Claim 6 (depends on 4) The method of claim 4, further comprising: sending, by the first access network device, the flight path information of the UAV to the UAV through a connection after establishing the connection with the UAV. ### Claim 7 A method for providing a UAV flight path, comprising: receiving, by a second access network device, a paging signaling carrying flight path information that is sent by a first access network device while a UAV in an inactive state; and sending, by the second access network device, a paging message configured to page the UAV, based on the paging signaling. ### Claim 8 (depends on 7) The method of claim 7, wherein the paging message comprises the flight path information of the UAV. ### Claim 9 (depends on 7) The method of claim 7, further comprising: sending, by the second access network device, the flight path information of the UAV to the UAV through the connection after establishing connection with the UAV. ### Claim 10 A method for obtaining a UAV flight path, comprising: receiving, by a UAV, a paging message sent by an access network device, the paging message being configured to page the UAV in an inactive state; and obtaining, by the UAV, flight path information from the paging message when the paging message includes the flight path information of the UAV. ### Claim 11 (depends on 10) The method of claim 10, further comprising: receiving, by the UAV, the flight path information sent by an access network device through a connection when the paging message does not include the flight path information and after establishing the connection with the access network device. ### Claim at position 12 12-22. (canceled) ### Claim 23 (depends on 1) An apparatus for providing a UAV flight path that is applied to a first access network device, comprising: a processor; and a memory that is configured to store instructions executable by the processor, wherein the processor is configured to perform the method of claim 1. ### Claim 24 (depends on 7) An apparatus for providing a UAV flight path that is applied to a second access network device, comprising: a processor; and a memory that is configured to store instructions executable by the processor, wherein the processor is configured to perform the method of claim 7. ### Claim 25 (depends on 10) An apparatus for obtaining a UAV flight path that is applied to a UAV, comprising: a processor; and a memory that is configured to store instructions executable by the processor, wherein the processor is configured to perform the method of claim 10. ### Claim at position 16 26-27.
