Obviously, the described embodiments are only a part of the embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of this application.
As shown in
In step S11, flight path information of an unmanned aerial vehicle is acquired, wherein the unmanned aerial vehicle is in an idle state.
In one embodiment, the flight path information can be configured by an unmanned aerial vehicle management system. The unmanned aerial vehicle management system can be, for example, UTM (UAS Traffic Management). The full name of UAS is Unmanned Aircraft System. The unmanned aerial vehicle management system can run on a terminal, and a communication connection may exist between the core network and the terminal, and then the flight path information of the unmanned aerial vehicle can be obtained from the terminal.
In one embodiment, the unmanned aerial vehicle is in the idle state, which means a state that a communication connection between the unmanned aerial vehicle and the base station is disconnected. Since a communication connection exists between the base station and the core network, the core network can determine whether the communication connection between the unmanned aerial vehicle and the base station is disconnected. For example, when there is data transmission between the unmanned aerial vehicle and the base station, it can be determined that there is a communication connection between the unmanned aerial vehicle and the base station. When there is no data transmission between the unmanned aerial vehicle and the base station, it can be determined that a communication connection between the unmanned aerial vehicle and the base station is disconnected, that is, the unmanned aerial vehicle is in an idle state.
In step S12, a tracking area where the unmanned aerial vehicle is located is determined, wherein at least one base station is located in the tracking area.
In one embodiment, one or more base stations can be set in the tracking area (TA). When the tracking area of the unmanned aerial vehicle changes, update request information for the tracking area can be generated and sent to the core network through the base station, and then the core network can determine the tracking area where the unmanned aerial vehicle is located.
In step S13, a first paging signaling is sent to the base station, wherein the first paging signaling contains the flight path information, and the first paging signaling is used to instruct the base station to send the flight path information to the unmanned aerial vehicle through a preset signaling.
In one embodiment, as for an unmanned aerial vehicle in an idle state, since no communication connection is established between the unmanned aerial vehicle and a base station, flight path information from a core network cannot be directly sent to the unmanned aerial vehicle through the base station. Therefore, a tracking area where the unmanned aerial vehicle is located can be determined first, and then a first paging signaling containing the flight path information can be sent to the base station in the tracking area, and the base station is instructed to send the flight path information to the unmanned aerial vehicle through a preset signaling through the first paging signaling, so that the flight path information can be sent from the core network to the unmanned aerial vehicle in the idle state, for the unmanned aerial vehicle to configure the flight path based on the flight path information. Compared with related technologies, the configuration of the flight path can be completed based on the operator's network, without establishing a dedicated link, and the configuration process is relatively simple.
In an embodiment, the format of the first paging signaling may be as shown in Table 1.
The core network may send the first paging signaling to the base station through the S1 interface, and the Flight Path Information in the first paging signaling is the flight path information.
In step S111, the flight path information is acquired from a terminal running an unmanned aerial vehicle management system, wherein the unmanned aerial vehicle management system is used to configure the flight path information for the unmanned aerial vehicle.
In one embodiment, the flight path information can be configured by an unmanned aerial vehicle management system. The unmanned aerial vehicle management system can run on a terminal, and a communication connection may exist between the core network and the terminal, and then the flight path information of the unmanned aerial vehicle can be acquired from the terminal.
The terminal that runs the unmanned aerial vehicle management system can be a server, a remote control and other devices.
In one embodiment, the tracking area where the unmanned aerial vehicle is located can change during movement of the unmanned aerial vehicle. When the tracking area where the unmanned aerial vehicle is located changes, the update request information for the tracking area can be generated and sent to the core network through the base station, for the core network to determine the tracking area where the unmanned aerial vehicle is located.
Optionally, the preset signaling includes at least one of:
In an embodiment, the core network may instruct the base station to send the flight path information to the unmanned aerial vehicle through the second paging signaling through the first paging signaling. In this case, the base station may broadcast the second paging signaling, and the identification information of the unmanned aerial vehicle may be included in the second paging signaling, so that when the unmanned aerial vehicle monitors the second paging signaling, it can be determined that the content in the second paging signaling needs to be acquired based on the identification information, for example, the flight path information carried by the second paging signaling is acquired. In this case, even if no communication connection is established between the unmanned aerial vehicle and the base station, the flight path information can still be obtained from the second paging signaling.
In one embodiment, the core network may instruct the base station to send the flight path information to the unmanned aerial vehicle through the Radio Resource Control (RRC) signaling or Media Access Control Control Element (MAC CE) through the first paging signaling. In this case, the base station can establish a communication connection with the unmanned aerial vehicle first, and when there is a communication connection with the unmanned aerial vehicle, the RRC signaling or MAC CE carrying the flight path information is sent to the unmanned aerial vehicle, such that the flight path information is sent to the unmanned aerial vehicle.
As shown in
In one embodiment, as for an unmanned aerial vehicle in an idle state, since no communication connection is established between the unmanned aerial vehicle and a base station, flight path information from a core network cannot be directly sent to the unmanned aerial vehicle through the base station. Therefore, a tracking area where the unmanned aerial vehicle is located can be determined first, and then a first paging signaling containing the flight path information can be sent to the base station in the tracking area, and the base station is instructed to send the flight path information to the unmanned aerial vehicle through a preset signaling through the first paging signaling.
After receiving the first paging signaling, the base station may generate the preset signaling according to the first paging signaling, and the preset signaling includes the flight path information, and then preset signaling is sent to the unmanned aerial vehicle, so that the flight path information can be sent from the core network to the unmanned aerial vehicle in the idle state, for the unmanned aerial vehicle to configure the flight path based on the flight path information. Compared with related technologies, the configuration of the flight path can be completed based on the operator's network, without establishing a dedicated link, and the configuration process is relatively simple.
In one embodiment, the tracking area where the unmanned aerial vehicle is located can change during movement of the unmanned aerial vehicle. When the tracking area where the unmanned aerial vehicle is located changes, the update request information for the tracking area can be generated and sent to the core network through the base station, for the core network to determine the tracking area where the unmanned aerial vehicle is located.

In this case, even if no communication connection is established between the unmanned aerial vehicle and the base station, the flight path information can still be obtained from the second paging signaling.
In one embodiment, the base station can establish a communication connection with the unmanned aerial vehicle first, and when there is a communication connection with the unmanned aerial vehicle, the RRC signaling or MAC CE carrying the flight path information is sent to the unmanned aerial vehicle, such that the flight path information is sent to the unmanned aerial vehicle from the core network.

Therefore, a tracking area where the unmanned aerial vehicle is located can be determined first, and then a first paging signaling containing the flight path information can be sent to the base station in the tracking area, and the base station is instructed to send the flight path information to the unmanned aerial vehicle through a preset signaling through the first paging signaling.
After receiving the first paging signaling, the base station may generate the preset signaling which contains the flight path information according to the first paging signaling, and then may acquire the flight path information from the preset signaling when the unmanned aerial vehicle receives the preset signaling, and configures the flight path based on the flight path information. Compared with related technologies, the configuration of the flight path can be completed based on the operator's network, without establishing a dedicated link, and the configuration process is relatively simple.
In one embodiment, the tracking area where the unmanned aerial vehicle is located can change during movement of the unmanned aerial vehicle.

Optionally, the preset signaling includes at least one of:
In one embodiment, the base station may broadcast the second paging signaling, and the second paging signaling may include the identification information of the unmanned aerial vehicle. The unmanned aerial vehicle may monitor the base station. When the second paging signaling is monitored, it can be determined that the content in the second paging signaling needs to be acquired based on the identification information, for example, the flight path information carried by the second paging signaling is acquired. In this case, even if no communication connection is established between the unmanned aerial vehicle and the base station, the flight path information can still be obtained from the second paging signaling.
In one embodiment, the unmanned aerial vehicle may establish a communication connection with the base station first, and when there is a communication connection with the base station, the RRC signaling or MAC CE carrying the flight path information may be received from the base station, so that the flight path information may be acquired from the core network.
As shown in
After the base station receives the first paging signaling, the preset signaling may be generated according to the first paging signaling. The preset signaling includes flight path information, and the base station sends the preset signaling to the unmanned aerial vehicle.
