Description

Technical Field

[0001] The present disclosure relates to the field of communications, and in particular, to an information transmission method and apparatus, and a storage medium. Background Art

[0002] An unmanned aerial vehicle, abbreviated as UAV (Unmanned Aerial Vehicle), is an unpiloted aircraft controlled by a radio remote control device and a self - contained program control device. In fact, UAV is a general term for unpiloted aircraft. From a technical perspective, it can be divided into: unmanned fixed - wing aircraft, unmanned vertical take - off and landing aircraft, unmanned airship, unmanned helicopter, unmanned multi - rotor aircraft, unmanned parafoil aircraft, etc.

[0003] With the rapid development of UAV technology, cost reduction, and function improvement, UAVs are increasingly used by ordinary consumers. And the applications of UAVs in industries are the real demand for UAVs. Currently, the applications in fields such as aerial photography, agriculture, plant protection, micro - self - shooting, express delivery, disaster relief, observing wild animals, monitoring infectious diseases, mapping, news reporting, power line inspection, disaster relief, film and television shooting, creating romance, etc. have greatly expanded the uses of UAVs themselves. Each country is actively expanding industrial applications and developing UAV technology.

[0004] In order to further expand the application scope of UAVs, the 3rd Generation Partnership Project (3GPP) has approved the establishment of the Enhanced Support for Aerial Vehicles project. The aim is to study and standardize how to enable the cellular network to provide services that meet the requirements for UAVs.

[0005] Generally, there are two flight modes for UAVs. One is the fixed mode, that is, the operator plans the flight route of the UAV on the controller, and then the UAV can fly according to the planned route, and the controller does not need to control the UAV all the time. The other mode is the dynamic mode, that is, the controller will remotely control the UAV in real - time all the time. For the fixed mode, since the flight route and trajectory of the UAV are fixed, the cellular network can predict which cellular network base stations the UAV will pass by.

[0006] Therefore, how UAVs can efficiently report flight path information is an urgent problem to be solved. Summary of the Invention

[0102] In step 101, report the capability information to the base station through the first Radio Resource Control (RRC) signaling.

[0103] In the embodiments of the present disclosure, the capability information is used to indicate whether the drone supports reporting the flight path information of the drone. Among them, the first RRC signaling can reuse the existing RRC signaling in the protocol or use a newly defined RRC signaling in the protocol. The present disclosure does not limit this.

[0104] In a possible implementation, if the first RRC signaling reuses the existing RRC signaling in the protocol and it is a Long Term Evolution (LTE) network, the first RRC signaling can be the UE-EUTRA-Capability signaling.

[0105] In another possible implementation, if the first RRC signaling reuses the existing RRC signaling in the protocol and it is a New Radio (NR) network, the first RRC signaling can be the UE-NR-Capability signaling.

[0106] In the above embodiments, the drone can report the capability information to the base station, and the capability information indicates whether the drone supports reporting the flight path information of the drone. After receiving it, the base station can configure the drone to report the flight path information according to the capability information, which improves the efficiency of reporting the flight path information of the drone, is simple to implement, and has high usability.

[0107] In some optional embodiments, referring to Figure 2 as shown Figure 2 It is a flowchart of an information transmission method shown according to an embodiment, which can be used for a drone. The method may include the following steps:

[0108] In step 201, report the capability information to the base station through the first information element in the first RRC signaling.

[0109] In the embodiments of the present disclosure, the capability information is used to indicate whether the drone supports reporting the flight path information of the drone. Among them, the first RRC signaling can reuse the existing RRC signaling in the protocol or use a newly defined RRC signaling in the protocol. The first information element can reuse the existing information element in the existing RRC signaling, or the first information element is a newly defined information element in the existing RRC signaling or the newly defined RRC signaling. The present disclosure does not limit this.

[0110] In a possible implementation, the first RRC signaling may reuse the existing RRC signaling in the protocol, and the first information element reuses the existing information element in the existing RRC signaling. If it is an LTE network, the first RRC signaling may be the UE-EUTRA-Capability signaling, and the first information element may be the OtherParameters information element in the UE-EUTRA-Capability signaling.

[0111] In another possible implementation, the first RRC signaling may reuse the existing RRC signaling in the protocol, and the first information element reuses the existing information element in the existing RRC signaling. If it is an NR network, the first RRC signaling may be the UE-NR-Capability signaling, and the first information element may be the OtherParameters information element in the UE-NR-Capability signaling.

[0112] In the above embodiments, the UAV can report the capability information to the base station, and the capability information indicates whether the UAV supports reporting the flight path information of the UAV. After receiving it, the base station can configure the UAV to report the flight path information according to the capability information, which improves the efficiency of reporting the flight path information of the UAV, is simple to implement, and has high usability.

[0113] In some alternative embodiments, refer to Figure 3 as shown Figure 3 FIG. is a flowchart of an information transmission method according to an embodiment, which can be used for a UAV. The method may include the following steps:

[0114] In step 301, report the capability information to the base station through the first Radio Resource Control (RRC) signaling.

[0115] In the embodiments of the present disclosure, the capability information is used to indicate whether the UAV supports reporting the flight path information of the UAV. Wherein, the first RRC signaling may reuse the existing RRC signaling in the protocol, or use a newly defined RRC signaling in the protocol. The present disclosure does not limit this.

[0116] In step 302, receive the second RRC signaling sent by the base station.

[0117] In the embodiments of the present disclosure, when the base station determines that the UAV supports reporting the flight path information based on the above capability information, it sends the second RRC signaling to the UAV, and the second RRC signaling carries the configuration information for the UAV to report the flight path information. Wherein, the second RRC signaling may reuse the existing RRC signaling in the protocol, or use a newly defined RRC signaling in the protocol. The present disclosure does not limit this.

[0118] In a possible implementation, the second RRC signaling multiplexes existing RRC signaling. If it is an LTE network, the second RRC signaling can be the RRC Connection Reconfiguration signaling.

[0119] In another possible implementation, the second RRC signaling multiplexes existing RRC signaling. If it is an NR network, the second RRC signaling can be the RRC Reconfiguration signaling.

[0120] In the above embodiments, after the UAV reports the capability information, it can receive the configuration information sent by the base station through the second RRC signaling. This configuration information can be used to configure the UAV to report the flight path information, improving the efficiency of reporting the flight path information of the UAV, with simple implementation and high usability.

[0121] In some alternative embodiments, the configuration information is used to indicate at least one of the following: whether to allow the UAV to report the flight path information; the conditions for reporting the flight path information; the format for reporting the flight path information; the maximum number of path points allowed to be reported.

[0122] Among them, the base station can determine whether to allow the UAV to report the flight path information according to its own capabilities.

[0123] Among them, the conditions for reporting the flight path information can include, but are not limited to, setting the duration of a blocking timer for the UAV. The UAV starts this blocking timer after each report of the flight path information and will not report the flight path information again before the blocking timer expires. This avoids wasting signaling resources caused by the UAV frequently reporting the flight path information.

[0124] Among them, the base station can determine the maximum number of path points allowed to be reported by the UAV in combination with its own capabilities.

[0125] It should be noted that the flight path information of the UAV corresponds to at least one path point. That is, in order to ensure that the UAV flies along the specified route, at least one path point needs to be determined on the flight route, and the UAV must pass through this path point during flight.

[0126] In the above embodiments, the base station can configure the UAV to report the flight path information based on the capability information reported by the UAV, with high usability.

[0127] In some alternative embodiments, the configuration information may be carried in a second information element of the second RRC signaling. Among them, the second RRC signaling may reuse an existing RRC signaling in the protocol, or use a newly defined RRC signaling in the protocol. The second information element may reuse an existing information element in the existing RRC signaling, or the second information element is a newly defined information element in the existing RRC signaling or the newly defined RRC signaling. The present disclosure does not limit this.

[0128] In a possible implementation manner, the second RRC signaling reuses an existing RRC signaling in the protocol, and the second information element reuses an existing information element in the existing RRC signaling. If it is an LTE network, the second RRC signaling may be an RRCConnectionReconfiguration signaling, and the second information element is an OtherConfig information element in the RRCConnectionReconfiguration signaling.

[0131] In step 401, capability information is reported to the base station through a first radio resource control (RRC) signaling.

[0132] In the embodiments of the present disclosure, the capability information is used to indicate whether the drone supports reporting the flight path information of the drone. Among them, the first RRC signaling may reuse an existing RRC signaling in the protocol, or use a newly defined RRC signaling in the protocol. The present disclosure does not limit this.

[0133] In a possible implementation manner, the first RRC signaling may reuse an existing RRC signaling in the protocol. If it is an LTE network, the first RRC signaling may be a UE-EUTRA-Capability signaling.

[0134] In another possible implementation, the first RRC signaling may reuse the existing RRC signaling in the protocol. If it is an NR network, the first RRC signaling may be the UE-NR-Capability signaling.

[0135] In step 402, receive the second RRC signaling sent by the base station.

[0136] In the embodiments of the present disclosure, when the base station determines that the drone supports reporting flight path information based on the above capability information, the base station sends the second RRC signaling to the drone, and the configuration information for the drone to report the flight path information is carried in the second RRC signaling. The second RRC signaling may reuse the existing RRC signaling in the protocol or use a newly defined RRC signaling in the protocol. The present disclosure does not limit this.

[0137] In a possible implementation, the second RRC signaling reuses the existing RRC signaling in the protocol. If it is an LTE network, the second RRC signaling may be the RRCConnectionReconfiguration signaling.

[0138] In another possible implementation, the second RRC signaling reuses the existing RRC signaling in the protocol. If it is an NR network, the second RRC signaling may be the RRCReconfiguration signaling.

[0139] In step 403, when the configuration information indicates that the base station allows the drone to report the flight path information, based on the configuration information, report the flight path information to the base station through the third RRC signaling.

[0140] Wherein, the third RRC signaling may reuse the existing RRC signaling in the protocol or use a newly defined RRC signaling in the protocol.

[0141] In a possible implementation, the third RRC signaling reuses the existing RRC signaling in the protocol. If it is an LTE network or an NR network, the third RRC signaling may be the UE Assistance Information signaling.

[0142] In the above embodiments, when the drone determines that the base station supports reporting flight path information according to the configuration information sent by the base station, the drone reports the flight path information to the base station based on the configuration information, which improves the efficiency of reporting the flight path information of the drone, is simple to implement, and has high usability.

[0143] In some alternative embodiments, the drone may report the flight path information to the base station through the third information element in the third RRC signaling. Among them, the third RRC signaling may reuse the existing RRC signaling in the protocol, or use a newly defined RRC signaling in the protocol. The third information element may reuse the existing information element in the existing RRC signaling, or the third information element is a newly defined information element in the existing RRC signaling or the newly defined RRC signaling. The present disclosure does not limit this.

[0144] In a possible implementation, the third RRC signaling may reuse the existing RRC signaling in the protocol, and the third information element reuses the existing information element in the existing RRC signaling. If it is an LTE network or an NR network, the third RRC signaling may be the UEAssistanceInformation signaling, and the third information element may be the flightPathInfoReport information element in the UEAssistanceInformation signaling.

[0145] In some alternative embodiments, refer to Figure 5 as shown Figure 5 is a flowchart of an information transmission method shown according to an embodiment, which can be used for a drone. The method may include the following steps:

[0146] In step 501, the capability information is reported to the base station through the first radio resource control (RRC) signaling.

[0147] In the embodiments of the present disclosure, the capability information is used to indicate whether the drone supports reporting the flight path information of the drone. Among them, the first RRC signaling may reuse the existing RRC signaling in the protocol, or use a newly defined RRC signaling in the protocol. The present disclosure does not limit this.

[0148] In a possible implementation, the first RRC signaling reuses the existing RRC signaling in the protocol. If it is an LTE network, the first RRC signaling may be the UE-EUTRA-Capability signaling.

[0149] In another possible implementation, the first RRC signaling reuses the existing RRC signaling in the protocol. If it is an NR network, the first RRC signaling may be the UE-NR-Capability signaling.

[0150] In step 502, the second RRC signaling sent by the base station is received.

[0151] In an embodiment of the present disclosure, when the base station determines, based on the above-mentioned capability information, that the drone supports reporting flight path information, the base station sends a second RRC signaling to the drone, and the configuration information for the drone to report the flight path information is carried in the second RRC signaling. Among them, the second RRC signaling can reuse an existing RRC signaling in the protocol, or use a newly defined RRC signaling in the protocol. The present disclosure does not limit this.

[0152] In a possible implementation, the second RRC signaling reuses an existing RRC signaling in the protocol. If it is an LTE network, the second RRC signaling can be an RRCConnectionReconfiguration signaling.

[0153] In another possible implementation, the second RRC signaling reuses an existing RRC signaling in the protocol. If it is an NR network, the second RRC signaling can be an RRCReconfiguration signaling.

[0154] In step 503, when the configuration information indicates that the base station allows the drone to report the flight path information, based on the configuration information, the flight path information corresponding to the first number of path points is reported through a third RRC signaling.

[0155] In an embodiment of the present disclosure, the first number of path points is the minimum value between the total number of path points on the drone's flight path and the maximum number of path points.

[0156] That is to say, when the total number of path points is less than or equal to the maximum number of path points that the drone can report, the drone can report the flight path information corresponding to the total number of path points to the base station. When the total number of path points is greater than the maximum number of path points that the drone can report, the drone can report the flight path information corresponding to the maximum number of path points that the drone can report to the base station. And at this time, there is still a part of the flight path information corresponding to the number of path points that has not been reported to the base station, and the flight path information corresponding to these remaining path points can be reported in a subsequent process.

[0157] In a possible implementation, if the total number of path points on the drone's flight path is greater than the maximum number of path points indicated by the configuration information, the third RRC signaling may include an indication information. The indication information is used to indicate that the drone has not reported all the flight path information.

[0158] Specifically, the indication information can be implemented by adding an indication bit. Optionally, the indication bit can be added to the third information element of the third RRC signaling to inform the base station that the drone has not reported all the flight path information.

[0159] Among them, the existing RRC signaling in the third RRC signaling multiplexing protocol is multiplexed, the existing information element in the existing RRC signaling is multiplexed in the third information element, the third RRC signaling is the UEAssistanceInformation signaling, and the third information element can be the flightPathInfoReport information element in the UEAssistanceInformation signaling.

[0160] In step 504, the flight path information corresponding to the second number of path points is reported to the base station through the new third RRC signaling.

[0161] Among them, the second number of path points is the difference between the total number of path points and the maximum number of path points. Similarly, the flight path information corresponding to the second number of path points can be added to the third information element of the new third RRC signaling.
