Description

Technical Field

[0001] This disclosure relates to, but is not limited to, the field of wireless communication technology, and particularly to an information transmission method and apparatus, communication equipment and storage medium. Background Technology

[0002] In recent years, aircraft such as unmanned aerial vehicles (UAVs) have become increasingly popular. Global interest in drone-based services has surged, encompassing various drone operations, personal entertainment through flight experiences, and cargo delivery. Remote control and data transmission capabilities are key enhancements for these services, attracting interest from both service providers / operators and drone manufacturers.

[0003] According to relevant research, the feasibility of UAVs connecting through terrestrial cellular systems and the necessary enhancements have been verified. The LTE (Long Term Evolution) system has been enhanced in terms of UL (Uplink) and DL (Downlink) interference and mobility.

[0004] In NR (New Radio), the applications suitable for UAV are more diverse, and UAV terminal equipment has lower latency and transmission rate requirements. Therefore, NR UAV needs to enhance mobility on the basis of LTE UAV. Summary of the Invention

[0005] This disclosure provides an information transmission method and apparatus, a communication device and a storage medium.

[0006] The first aspect of this disclosure provides an information transmission method, executed by a user equipment (UE), the method comprising:

[0007] Obtain the sending parameters; wherein, the sending parameters include: the sending configuration provided by the network device, or the parameters agreed upon by the protocol;

[0008] The path information of the UE is sent according to the sending parameters.

[0009] A second aspect of this disclosure provides an information transmission method, executed by a network device, the method comprising:

[0010] The system receives path information of the user equipment (UE) sent by the UE according to transmission parameters; wherein the transmission parameters include: transmission configuration provided by the network device, or parameters agreed upon by the protocol.

[0011] A third aspect of this disclosure provides an information transmission apparatus, which is applied to a user equipment (UE), the apparatus comprising:

[0012] The acquisition module is configured to acquire sending parameters; wherein, the sending parameters include: sending configuration provided by the network device, or parameters agreed upon by the protocol;

[0013] The sending module is configured to send the path information of the UE according to the sending parameters.

[0014] A fourth aspect of this disclosure provides an information transmission apparatus, which is applied to a network device, the apparatus comprising:

[0015] The receiving module is configured to receive path information of the user equipment (UE) sent by the UE according to the sending parameters; wherein the sending parameters include: sending configuration provided by the network device, or parameters agreed upon by the protocol.

[0016] A fifth aspect of this disclosure provides a communication device, including a processor, a memory, and an executable program stored in the memory and capable of being executed by the processor, wherein when the processor executes the executable program, it performs the information transmission method as provided in the first or second aspect described above.

[0017] A sixth aspect of this disclosure provides a computer storage medium storing an executable program; the executable program, when executed by a processor, can implement the information transmission method provided in the first or second aspect described above.

[0018] The technical solution provided in this disclosure allows the UE to send its path information according to the transmission configuration or protocol parameters provided by the network device. This makes the path information sent by the UE more targeted, ensuring that the path information received by the network device is the information it needs. Since the UE's path information is valid and usable by the network device, it can effectively utilize the UE's path information for UE mobility management. Furthermore, because the path information sent by the UE is the information required by the network device, the transmission of unnecessary information is reduced, thereby reducing signaling overhead.

[0033] Please refer to Figure 1 This illustration shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include at least one UE11 and at least two access network devices12.

[0034] UE11 can be a device that provides voice and / or data connectivity to a user. UE11 can communicate with one or more core networks via a Radio Access Network (RAN), and through the core network, the UE can connect to external network devices such as the Internet and other UEs. UE11 can be an Internet of Things (IoT) UE, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT UE; for example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (UE). Alternatively, UE11 can also be a device of an unmanned aerial vehicle (UAV). Alternatively, UE11 can also be an in-vehicle device, such as a vehicle computer with wireless communication capabilities, or a wireless communication device connected to an external vehicle computer. Alternatively, UE11 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0035] Access network device 12 can be a network-side device in a wireless communication system. This wireless communication system can be a fourth-generation mobile communication (4G) system, also known as a Long Term Evolution (LTE) system; or it can be a 5G system, also known as a New Radio (NR) system or a 5G NR system. Alternatively, it can be a next-generation system after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network) or MTC (Machine Type Communication) system.

[0036] The access network device 12 can be an evolved NB (eNB) used in a 4G system. Alternatively, the access network device 12 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When the access network device 12 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DUs). The central unit is equipped with a protocol stack of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of the access network device 12.

[0037] Access network device 12 and UE11 can establish a wireless connection via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as a new air interface; or, the wireless air interface can also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.

[0038] UE11 can also establish E2E (End to End) or D2D (Device to Device) connections. For example, in vehicle-to-everything (V2X) communication scenarios such as V2V (vehicle to vehicle), V2I (vehicle to Infrastructure), and V2P (vehicle to pedestrian) communication.

[0039] Access network device 12 can be located in a communication system integrated with a satellite communication system and can provide connectivity services for satellites, enabling satellites to access the core network. For example, access network device 12 can be an access network device with satellite gateway functionality in a communication system, such as a gateway device, ground station device, or non-terrestrial network gateway (NTN-Gateway).

[0040] The aforementioned wireless communication system may also include a core network device 13. Several access network devices 12 are connected to the core network device 13.

[0041] For example, core network device 13 may be a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, the core network device may be an Enhanced Serving Mobile Location Centre (E-SMLC), etc.

[0042] As an example, core network device 13 may be an Access and Mobility Management Function (AMF), a Location Management Function (LMF), a Gateway Mobile Location Center (GMLC), etc. The implementation of core network device 13 is not limited in this disclosure.

[0043] It should be noted that, Figure 1 The network architecture shown is merely an example applicable to the embodiments of this disclosure and does not constitute a limitation on the scope of application of the embodiments of this disclosure.

[0044] To facilitate understanding by those skilled in the art, this disclosure provides multiple embodiments to clearly illustrate the technical solutions of the embodiments of this disclosure. Of course, those skilled in the art will understand that the multiple embodiments provided in this disclosure can be executed individually, or in combination with the methods of other embodiments in this disclosure, or individually or in combination with some methods in other related technologies; this disclosure does not limit these aspects.

[0045] To enhance mobility, in LTE UAVs, a Radio Resource Control (RRC) message can be used to request the UE to report its planned flight path to the eNB (evolved Node B). More specifically, the UE can indicate its planned future location. For UE mobility, the eNB can integrate this information to configure handover and other mobility features. For example, based on this information, the eNB may be able to know in advance which cell is suitable for UE access and can be used as the UE's target cell. The UAV flies along a pre-configured path. When the UAV approaches the cell edge, or even before it reaches the cell edge, the serving eNB can begin handover preparation with a nearby target eNB. For example, it can select a target eNB within the target eNB range of the next point on the flight path, forward the terminal context in advance, pre-configure radio resources for the terminal in the target eNB, and then send a handover command to the terminal under high-quality radio link conditions. This significantly reduces the probability of handover failure when the UAV performs a handover along its flight path.

[0046] In LTE UAVs, based on network device requests, the UAV UE reports flight paths using UEInformationRequest and UEInformationResponse information. When the UE receives a UEInformationRequest from the network device, it sends its flight path information to the network via UEInformationResponse, as requested by the network device.

[0047] During flight path reporting, the UE reports its flight path based on a request from the network device. However, the network device's request only instructs the UE to report flight path information and whether the flight path information includes a timestamp. Therefore, how the UE reports its flight path depends on the UE implementation, which may result in the reported flight path information not being entirely useful. The serving base station might be more interested in knowing when the UE plans to leave its coverage area and what potential target base stations it might be targeting. However, since the granularity and content of the currently reported flight path information are determined based on the UE implementation, the reported flight path information may not be well-suited for UE mobility management.

[0048] Figure 2 This is a flowchart illustrating an information transmission method according to an exemplary embodiment. The information transmission method is executed by the UE, such as... Figure 2 As shown, the method may include the following steps:

[0049] 201: Obtain sending parameters; wherein, the sending parameters include: sending configuration provided by the network device, or parameters agreed upon by the protocol;

[0050] 202: Send the path information of the UE according to the sending parameters.

[0051] In some examples, the UE can be a flying device and / or a ground-mobile device. Here, the flying device can be, for example, an unmanned aerial vehicle. In other examples, the UE can also be a UE carried by a person riding in an aircraft.

[0052] In some examples, the UE may be located on and integrated into the UAV; for example, the UE may be able to provide a data connection for controlling or communicating with the UAV.

[0053] In some examples, the UE can be the payload of the UAV and perform functions separate from the UAV.

[0054] The aforementioned UAVs can include any type of unmanned aerial vehicle. For example, a UAV can be an unmanned fixed-wing aircraft, an unmanned airship, an unmanned helicopter, or any other flying and remotely controlled device.

[0055] In some examples, the network device may be a base station, such as a gNB, eNB, etc. The network device may also be any other network node capable of serving a UE in the communication system, such as a wireless device or a machine-type communication device.

[0056] In this embodiment, the transmission parameters are used by the UE to transmit its path information. These transmission parameters can be transmission configurations provided by the network device or parameters agreed upon in the protocol.

[0057] In some examples, the sending parameters are used to determine the path point information of the path points that the UE plans to traverse, which needs to be reported.

[0058] In some examples, the transmission configuration may include configuration information for determining the path information of the UEs that need to be reported. For example, the configuration information may include reference point information. In other examples, the configuration information may also include reference point information and threshold values.

[0059] In some examples, if the UE is a flying device, the path information is flight path information, indicating a flight path. For example, a flight path in three-dimensional space. If the UE is a road-based mobile device, the path information is road path information, indicating a road movement path. This road movement path includes, but is not limited to, highway and / or rail transit paths.

[0060] In some examples, the UE's path information may indicate the planned movement path or waypoints within that path.

[0061] The planned movement path of the UE may include N path points; the location information of the N path points is ordered sequentially and corresponds one-to-one with their respective time information. Barring unforeseen circumstances, the UE will sequentially pass through the N path points in the planned movement path according to the planned time.

[0062] In some examples, the UE's path information includes path point information for the path points the UE plans to traverse. Here, the UE can send path point information for one or more path points in the planned mobile path according to the transmission parameters.

[0063] In some examples, the path point information of the path points that the UE plans to traverse can characterize the movement status of the UE as it plans to pass through those path points.

[0064] For example, the path point information of a path point that the UE plans to traverse may include, but is not limited to, at least one of the following:

[0065] The planned moving or flying speed of the UE as it passes through this waypoint;

[0066] The planned time for the UE to pass through this path point;

[0067] Location information of the path points that the UE plans to pass through;

[0068] The path point index of the path point that the UE plans to traverse.

[0069] In this embodiment of the disclosure, the path information includes at least time information and / or location information. The time information can be represented by a timestamp.

[0070] A timestamp can indicate an absolute time or a time difference relative to a reference time. This reference time can be an absolute time.

[0071] Location information may include, but is not limited to, one or more of longitude, latitude, and altitude. In some examples, the location information may also include elevation information.

[0072] In some examples, the location information may include absolute location information such as latitude and longitude, or relative location information relative to a reference point. This reference point can be any pre-defined location. For example, the reference point could be the absolute location information at the start time of the UE's current movement, or an absolute location specified within a region such as the equator.

[0073] In some examples, if the UE receives the transmission configuration provided by the network device, the UE can send the UE's path information according to the transmission configuration. If the UE does not receive the transmission configuration provided by the network device, the UE can send the UE's path information according to the parameters agreed upon in the protocol.

[0074] In some examples, upon receiving the transmission configuration provided by the network device, the UE can transmit its path information according to the parameters agreed upon in the protocol; or, the UE can randomly transmit its path information according to either the transmission configuration provided by the network device or the parameters agreed upon in the protocol.

[0075] In this embodiment, the UE can use the transmission configuration or protocol-defined parameters provided by the network device as transmission parameters to send its path information to the network device. After the UE sends the path information to the network device, the network device can perform cell handover preparations in advance before the UE reaches certain cells, enabling fast and efficient handover between different cells within the network. These cells may include, but are not limited to, terrestrial network (TN) cells and / or non-terrestrial network (NTN) cells. The network device can also pre-configure appropriate measurement settings for the UE based on this path information.

[0076] In this embodiment, the UE can send its path information according to the transmission configuration or parameters specified in the protocol provided by the network device. This makes the path information sent by the UE more targeted, ensuring that the path information received by the network device is the information it needs. Since the UE's path information is valid and usable by the network device, it can effectively utilize the UE's path information for UE mobility management. Furthermore, because the path information sent by the UE is the information required by the network device, the transmission of unnecessary information is reduced, thereby reducing signaling overhead.

[0077] In one embodiment, obtaining the sending parameters may include:

[0078] Receive request information sent by the network device, wherein the request information includes the sending configuration.

[0079] The request information is used to request the UE to send its path information.

[0080] In some examples, the network device may receive a request message containing the transmission configuration sent via an instruction. This instruction may be a physical layer instruction or a higher-layer instruction. The higher-layer instruction may be an RRC instruction or a MAC control element (CE).

[0081] In some examples, the UE can receive a UEInformationRequest message containing the transmission configuration sent by the network device. Accordingly, the UE can send its path information to the network device via a UEInformationResponse message, based on the transmission configuration.

[0082] In some examples, when the UE acts as a flight device, it can encapsulate the path information sent according to the transmission parameters into a FlightPathInfoReport and report it to the network device.

[0083] In one embodiment, such as Figure 3 As shown, an information transmission method is provided, which is executed by a UE. The method may include the following steps:

[0084] 301: Receive request information sent by the network device, wherein the request information includes the sending configuration;

[0085] 302: According to the transmission configuration, transmit the path information of the UE.

[0086] In some examples, the sending configuration included in the request message is used to configure one or more alternative reference points.

[0087] In this embodiment, the network device can send a request message to the UE, requesting the UE to report path information. The sending configuration carried in the request message is used to configure one or more alternative reference points. In this way, the network device configures one or more alternative reference points for the UE, and the UE can report the path point information of the path point that is closest to the location of the alternative reference point, such as the time information and / or location information of the path point with the shortest distance to the alternative reference point.

[0088] In other examples, the sending configuration included in the request message is used to configure one or more alternative reference points and the corresponding threshold values ​​for each alternative reference point.

[0089] In this embodiment, the network device can send a request message to the UE, requesting the UE to report path information. The sending configuration carried in the request message is used to configure one or more alternative reference points and the threshold value corresponding to each alternative reference point. The UE can determine which path point in the UE's movement path and when the distance from the alternative reference point meets the threshold value requirement (e.g., the distance is less than or equal to the threshold value), and report it to the network device and / or the reported path information only contains the path point information that meets the threshold value requirement, such as the time information and / or location information of the path point whose distance from the alternative reference point meets the threshold value requirement.

[0090] In one embodiment, the sending configuration includes:

[0091] Location indication information for one or more alternative reference points.

[0092] The location indication information of the alternative reference points can be used to indicate the location of the alternative reference points.

[0093] For example, the location indication information of the candidate reference point may indicate that the candidate reference point is the current serving cell of the UE. Alternatively, the location indication information of the candidate reference point may indicate that the candidate reference point is a neighboring cell of the current serving cell of the UE.

[0094] In some examples, the location indication information of the alternative reference points includes at least one of the following:

[0095] The index of the alternative reference points;

[0096] The cell identifier of the candidate reference point is used to indicate the cell corresponding to the candidate reference point. The cell is: the UE's current serving cell, the neighboring cell of the current serving cell, or a specific cell.

[0097] The absolute location information of the alternative reference points.

[0098] In some examples, the index of the alternative reference point can be the number of the alternative reference point, which can be, for example, a numeric number.

[0099] The cell identifier of the candidate reference point is used to identify the cell corresponding to the candidate reference point. In some examples, the cell corresponding to the candidate reference point may include the UE's serving cell, neighboring cells, or a specific cell.

[0100] In some examples, the absolute location information of the candidate reference point may include the absolute longitude and absolute latitude of the candidate reference point.

[0101] In some examples, the absolute position information of the candidate reference point may also include the absolute height of the candidate reference point.

[0102] In this embodiment, the transmission configuration provided by the network device to the UE includes location indication information of one or more alternative reference points. In this way, the UE can transmit the UE's path information according to the location indicated by the location indication information of one or more alternative reference points.

[0103] For example, the UE can determine the location of one or more alternative reference points based on the location indication information of one or more alternative reference points, and send the path point information of the path point in the UE's movement path that is closest to the location of each alternative reference point.

[0104] In one embodiment, the path information includes: path point information of one or more first path points; the first path point is: among the one or more path points that the UE plans to pass through, the path point with the shortest distance to the target reference point; wherein, the target reference point is one of the candidate reference points.

[0105] In some examples, there can be one or more target reference points that are closest to the first path point. For example, if a path point is located between two candidate reference points in the path points that the UE plans to traverse, and the path point is closest to each of the two candidate reference points, then the path point can be determined as the first path point.

[0106] In other examples, there can be one or more first path points that are closest to the same target reference point. For example, among the path points that the UE plans to traverse, if there is an alternative reference point between two path points, and the alternative reference point is closest to each of the two path points, then the alternative reference point is used as the target reference point, and both path points are determined to be first path points.

[0107] For example, the distance between the path points that the UE plans to traverse and the alternative reference points is the distance in three-dimensional space.

[0108] In this embodiment, the UE can select the path point with the shortest distance to each candidate reference point for sending the configuration instruction as the first path point, and send path information containing the path point information of the first path point.

[0109] In one embodiment, the path point information of the first path point includes at least one of the following:

[0110] Location information of the first path point;

[0111] The time information of the UE's planned passage through the first path point;

[0112] The path point index of the first path point;

[0113] The location indication information of the target reference point with the shortest distance to the first path point;

[0114] The relative position information between the first path point and the target reference point.

[0115] In some examples, the time information can be absolute time information (AbsoluteTimeInfo).

[0116] The Information Element (IE) AbsoluteTimeInfo represents absolute time, formatted as YY-MM-DD HH:MM:SS, and encoded using BCD (binary-encoded decimal). The first or leftmost bit of the bit string represents the highest bit of the absolute time, and so on.

[0117] In some examples, location information can be represented by CommonLocationInfo.

[0118] The CommonLocationInfo element is used to transmit detailed location information available on the UE to correlate measurement values ​​with UE location information.

[0119] In other examples, location information can be represented by LocationCoordinates.

[0120] In some examples, the location information of the first waypoint is used to indicate the flight position of the UE when it plans to pass through the first waypoint.

[0121] For example, the location information of the first path point can be location information in three-dimensional space, which may include longitude information, latitude information and altitude information.

[0122] In some examples, the time information for when the UE plans to pass through the first waypoint can be a timestamp. For example, the timestamp when the UE arrives at the first waypoint.

[0123] In some examples, the path point index of the first path point is used to identify the first path point that the UE plans to traverse.

[0124] The path point index can be a path point number. For example, the path point number can be a number sequentially numbered for the path points the UE will traverse according to the plan. Alternatively, the path point number can be a number sequentially numbered for the path points the UE will traverse according to the plan. It is worth noting that the path point index can also be a random number, as long as it uniquely represents a path point; this embodiment does not impose specific limitations on this.

[0125] In some examples, the location indication information of the target reference point may include at least one of the following:

[0126] The index of the target reference point;

[0127] The cell identifier of the target reference point is used to indicate the cell corresponding to the target reference point. The cell is: the UE's current serving cell, the neighboring cell of the current serving cell, or a specific cell.

[0128] The absolute position information of the target reference point.

[0129] In some examples, the relative position information between the first path point and the target reference point can be determined based on the position information of the first path point and the absolute position information of the target reference point.

[0130] In some examples, the relative position information between the first waypoint and the target reference point may include relative longitude and relative latitude. In some examples, the relative position information may also include relative altitude.

[0131] In one embodiment, the sending configuration includes:

[0132] Location indication information for one or more alternative reference points;

[0133] One or more first threshold values; wherein different alternative reference points correspond to the same or different first threshold values.

[0134] In some examples, all alternative reference points can correspond to the same first threshold value. In other examples, different alternative reference points can correspond to different first threshold values. That is, the field corresponding to the first threshold value can be a general value that applies to all configured alternative reference points, or the first threshold value can be configured separately for each alternative reference point.

[0135] In other examples, some of the alternative reference points may be configured with the same first threshold value, while different alternative reference points in another group may be configured with different first threshold values.

[0136] In some examples, an alternative reference point may correspond to the current serving cell, and the alternative reference point and its corresponding threshold value are used to indicate the coverage area of ​​the current serving cell. Alternatively, an alternative reference point may correspond to a neighboring cell, and the alternative reference point and its corresponding threshold value are used to indicate the coverage area of ​​the neighboring cell.

[0137] In one embodiment, the path information includes: path point information of one or more second path points;

[0138] The second path point is: among one or more path points that the UE plans to pass through, the path point whose distance to the candidate reference point meets a first preset condition; wherein, the first preset condition is associated with the first threshold value.

[0139] In some examples, the UE can determine, for each candidate reference point, a path point whose distance from the candidate reference point satisfies a first preset condition among one or more path points that the UE plans to traverse.

[0140] In one embodiment, the distance between the second path point that the UE plans to traverse and one or more of the alternative reference points is less than or equal to the corresponding first threshold value;

[0141] or,

[0142] The distance between the second path point that the UE plans to pass through and the nearest alternative reference point is greater than or equal to the corresponding first threshold value;

[0143] or,

[0144] The distance between the second path point that the UE plans to pass through and the previous path point adjacent to the second path point and the same alternative reference point, respectively, is greater than the corresponding first threshold value, and the other is less than or equal to the corresponding first threshold value.

[0145] or,

[0146] The distance between the second path point that the UE plans to pass through and the next path point adjacent to the second path point and the same alternative reference point, respectively, is greater than the corresponding first threshold value, and less than or equal to the corresponding first threshold value.

[0147] In some examples, for each candidate reference point, the UE can determine the path point whose distance from the candidate reference point is less than or equal to a first threshold value corresponding to the candidate reference point among one or more path points that the UE plans to traverse as the first path point.

[0148] In this embodiment, the number of candidate reference points whose distance to a certain second path point is less than or equal to the corresponding first threshold value can be one or more.

[0149] For example, if a path point is located within the cell coverage area of ​​a candidate reference point (determined by the first threshold value corresponding to the candidate reference point), the path point can be used as a second path point.

[0150] For example, if a path point is located within the overlapping coverage area of ​​different candidate reference points (the cell coverage area of ​​each candidate reference point is determined by the first threshold value corresponding to each candidate reference point), the path point can be used as a second path point.

[0151] For example, if a path point is located between candidate reference point A and candidate reference point B, and the distance between the path point and candidate reference point A is less than or equal to the first threshold value corresponding to candidate reference point A, and the distance between the path point and candidate reference point B is less than or equal to the first threshold value corresponding to candidate reference point B, the path point can be used as a second path point. The UE can include the path point information of the second path point in the path information reported to the network device.

[0152] In some examples, for each candidate reference point, the UE can determine the path point that the UE plans to pass through that candidate reference point is closest to that candidate reference point. If the distance between the determined path point and the candidate reference point is greater than or equal to the first threshold value corresponding to the candidate reference point, then the path point is used as the second path point, and the path point information of the second path point is included in the path information reported to the network device.

[0153] In some examples, for each candidate reference point, the UE can determine the path point that the UE plans to traverse, whose distance from the candidate reference point is less than or equal to the first threshold value corresponding to the candidate reference point. If the distance between the previous path point adjacent to the candidate reference point and the candidate reference point is greater than the first threshold value corresponding to the candidate reference point, then the path point is used as the second path point, and the path point information of the second path point is included in the path information reported to the network device.

[0154] In some examples, for each candidate reference point, the UE can determine the path points that the UE plans to traverse that are at a distance greater than the first threshold value corresponding to the candidate reference point. If the distance between the previous path point adjacent to the candidate reference point and the candidate reference point is less than or equal to the first threshold value corresponding to the candidate reference point, then the path point is used as the second path point, and the path point information of the second path point is included in the path information reported to the network device.

[0155] In some examples, for each candidate reference point, the UE can determine the path points that the UE plans to traverse that are less than or equal to the first threshold value corresponding to the candidate reference point. If the distance between the next adjacent path point and the candidate reference point is greater than the first threshold value corresponding to the candidate reference point, then the path point is used as the second path point, and the path point information of the second path point is included in the path information reported to the network device.

[0156] In some examples, for each candidate reference point, the UE can determine the path points that the UE plans to traverse that are more distant from the candidate reference point than the first threshold value corresponding to the candidate reference point. If the distance between the next adjacent path point and the candidate reference point is less than or equal to the first threshold value corresponding to the candidate reference point, then the path point is used as the second path point, and the path point information of the second path point is included in the path information reported to the network device.

[0157] In one embodiment, the path point information of the second path point includes at least one of the following:

[0158] The location information of the second path point;

[0159] The time information of the UE's planned passage through the second path point;

[0160] The path point index of the second path point;

[0161] The location indication information of the alternative reference point whose distance from the second path point satisfies the first preset condition.

[0162] In some examples, the location information of the second waypoint is used to indicate the flight position of the UE when it plans to pass through the second waypoint.

[0163] For example, the location information of the second path point can be location information in three-dimensional space, which may include latitude and longitude information and altitude information.

[0164] In some examples, the time information for when the UE plans to pass through the second waypoint can be a timestamp. For example, the timestamp when the UE arrives at the second waypoint.

[0165] In some examples, the path point index of the second path point is used to identify the first path point that the UE plans to traverse.

[0166] The path point index can be a path point number. For example, the path point number can be a number sequentially numbered for the path points the UE will traverse according to the plan. Alternatively, the path point number can be a number sequentially numbered for the path points the UE will traverse according to the plan. It is worth noting that the path point index can also be a random number, as long as it uniquely represents a path point; this embodiment does not impose specific limitations on this.

[0167] In one embodiment, the path information further includes:

[0168] Duration information indicates the duration for which the distance between one or more path points that the UE plans to traverse and the alternative reference point satisfies the first preset condition.

[0169] In this embodiment, for each candidate reference point, the UE can determine, among the path points that the distance between the candidate reference point and the path point meets the first preset condition, as well as the duration for which the candidate reference point and the path point meet the first preset condition, and include the duration in the path information reported by the UE to the network device.

[0170] In one embodiment, the location indication information of the alternative reference point includes at least one of the following:

[0171] The index of the alternative reference points;

[0172] The cell identifier of the candidate reference point is used to indicate the cell corresponding to the candidate reference point. The cell is: the UE's current serving cell, the neighboring cell of the current serving cell, or a specific cell.

[0173] The absolute location information of the alternative reference points.

[0174] In one embodiment, the parameters agreed upon in the protocol include one of the following:

[0175] Time interval information, used to indicate the time interval between two consecutive transmissions of the path information;

[0176] Distance interval information is used to indicate the distance interval traversed by the UE when the path information is transmitted between two consecutive transmissions;

[0177] The path information transmitted in different transmissions includes path point information of different path points that the UE plans to traverse.

[0178] In some examples, the time interval between two consecutive transmissions of the path information can be set according to the protocol, and is not specifically limited here. For example, the time interval can be 10 seconds or 20 seconds between transmissions of the path information.

[0179] In some examples, the distance interval between two consecutive transmissions of the path information can be set according to the protocol, and is not specifically limited here. For example, the distance interval can be once every 1000 meters or 1500 meters.

[0180] In this embodiment, the path information transmitted in different sessions includes path point information of different path points that the UE plans to traverse.

[0181] In some examples, the UE can determine the path point information of the path points included in different path information based on the time information and / or location information of each path point planned to be traversed.

[0182] For example, taking the transmission of path information at 10-second intervals as an example, if the UE plans to pass through path point 1, path point 2, path point 3, path point 4, and path point 5 at the 1s, 5s, 8s, 12s, and 16s respectively, then the path information transmitted by the UE for the first time (e.g., at t=0s) may include the path point information of path 1, path 2, and path 3; the path information transmitted by the UE for the second time (e.g., at t=10s) may include the path point information of path 4 and path 5.

[0183] In one embodiment, the path information includes: path point information of a third path point; the third path point is: among one or more path points that the UE plans to pass through, the path point with the shortest distance to the UE's current location;

[0184] or,

[0185] The third path point is: among one or more path points that the UE plans to pass through, the path point whose distance from the UE's current location meets the second preset condition; wherein, the second preset condition is related to a preset second threshold value.

[0186] In some examples, the current location of the UE can be the relative location of the UE with respect to the serving cell, or it can be the absolute location of the UE.

[0187] In some examples, when the distance between the third path point and the current position of the UE is less than or equal to the second threshold value, the distance between the third path point and the current position of the UE satisfies the second preset condition.

[0188] In other examples, when the distance between the third path point and the current position of the UE is greater than the second threshold value, the distance between the third path point and the current position of the UE satisfies the second preset condition.

[0189] In one embodiment, the parameters agreed upon by the protocol include: the time interval information, and the path information includes at least one of the following:

[0190] The location information of the third path point;

[0191] The path point index of the third path point;

[0192] The time interval information;

[0193] The time information corresponding to the starting path point in the UE's flight path.

[0194] In some examples, the location information of the third waypoint is used to indicate the flight position of the UE when it plans to pass through the third waypoint.

[0195] For example, the location information of the third path point can be location information in three-dimensional space, which may include latitude and longitude information and altitude information.

[0196] In some examples, the altitude information can be used to indicate the UE's flight altitude. For example, the UE's flight altitude can be the UE's altitude relative to sea level or the UE's altitude relative to the base station.

[0197] In one embodiment, the parameters agreed upon by the protocol include: the distance interval information, and the path information includes at least one of the following:

[0198] The time information of the UE's planned passage through the third path point;

[0199] The path point index of the third path point;

[0200] The distance interval information;

[0201] The flight direction or movement direction of the UE;

[0202] The flight speed or movement speed of the UE;

[0203] The location information and / or time information corresponding to the starting path point in the flight path of the UE.

[0204] In some examples, the time information for when the UE plans to pass through the third waypoint can be a timestamp. For example, the timestamp when the UE arrives at the third waypoint.

[0205] In some examples, the path point index of the third path point is used to identify the third path point that the UE plans to traverse.

[0206] The path point index can be a path point number. For example, the path point number can be a number sequentially numbered for the path points the UE will traverse according to the plan. Alternatively, the path point number can be a number sequentially numbered for the path points the UE will traverse according to the plan. It is worth noting that the path point index can also be a random number, as long as it uniquely represents a path point; this embodiment does not impose specific limitations on this.

[0207] In some examples, the flight speed of the UE can be a vertical speed, a horizontal speed, or a relative speed with respect to the ground.

[0208] In some examples, the location information corresponding to the starting path point in the UE's flight path is used to indicate the UE's initial flight position. For example, the initial flight position can be location information in three-dimensional space, or it can include latitude and longitude information, and it can also include the UE's altitude information.

[0209] The time information corresponding to the starting path point in the UE's flight path can be a timestamp. For example, the timestamp when the UE passes the starting path point.

[0210] Figure 4 This is a flowchart illustrating an information transmission method according to an exemplary embodiment. The information transmission method is executed by a network device, such as... Figure 4 As shown, the method may include the following steps:

[0211] 401: Receive the path information of the UE sent by the UE according to the sending parameters; wherein the sending parameters include: the sending configuration provided by the network device, or the parameters agreed upon by the protocol.

[0212] In some examples, the UE can be a flying device and / or a ground-mobile device. Here, the flying device can be, for example, an unmanned aerial vehicle. In other examples, the UE can also be a UE carried by a person riding in an aircraft.

[0213] In some examples, the UE may be located on and integrated into the UAV; for example, the UE may be able to provide a data connection for controlling or communicating with the UAV.

[0214] In some examples, the UE can be the payload of the UAV and perform functions separate from the UAV.

[0215] The aforementioned UAVs can include any type of unmanned aerial vehicle. For example, a UAV can be an unmanned fixed-wing aircraft, an unmanned airship, an unmanned helicopter, or any other flying and remotely controlled device.

[0216] In some examples, the network device may be a base station, such as a gNB, eNB, etc. The network device may also be any other network node capable of serving a UE in the communication system, such as a wireless device or a machine-type communication device.

[0217] In this embodiment, the transmission parameters are used by the UE to transmit its path information. These transmission parameters can be transmission configurations provided by the network device or parameters agreed upon in the protocol.

[0218] In some examples, the sending parameters are used to determine the path point information of the path points that the UE plans to traverse, which needs to be reported.

[0219] In some examples, the transmission configuration may include configuration information for determining the path information of the UEs that need to be reported. For example, the configuration information may include reference point information. In other examples, the configuration information may also include reference point information and threshold values.

[0220] In some examples, if the UE is a flying device, the path information is flight path information, indicating a flight path. For example, a flight path in three-dimensional space. If the UE is a road-based mobile device, the path information is road path information, indicating a road movement path. This road movement path includes, but is not limited to, highway and / or rail transit paths.

[0221] In some examples, the UE's path information may indicate the planned movement path or waypoints within that path.

[0222] The planned movement path of the UE may include N path points; the location information of the N path points is ordered sequentially and corresponds one-to-one with their respective time information. Barring unforeseen circumstances, the UE will sequentially pass through the N path points in the planned movement path according to the planned time.

[0223] In some examples, the UE's path information includes path point information for the path points the UE plans to traverse. Here, the UE can send path point information for one or more path points in the planned mobile path according to the transmission parameters.

[0224] In some examples, the path point information of the path points that the UE plans to traverse can characterize the movement status of the UE as it plans to pass through those path points.

[0225] For example, the path point information of a path point that the UE plans to traverse may include, but is not limited to, at least one of the following:

[0226] The planned moving or flying speed of the UE as it passes through this waypoint;

[0227] The planned time for the UE to pass through this path point;

[0228] Location information of the path points that the UE plans to pass through;

[0229] The path point index of the path point that the UE plans to traverse.

[0230] In this embodiment of the disclosure, the path information includes at least time information and / or location information. The time information can be represented by a timestamp.

[0231] A timestamp can indicate an absolute time or a time difference relative to a reference time. This reference time can be an absolute time.

[0232] Location information may include, but is not limited to, one or more of longitude, latitude, and altitude. In some examples, the location information may also include elevation information.

[0233] In some examples, the location information may include absolute location information such as latitude and longitude, or relative location information relative to a reference point. This reference point can be any pre-defined location. For example, the reference point could be the absolute location information of the terminal device at the start time of its current movement, or an absolute location specified within a region such as the equator.

[0234] In this embodiment, the network device receives the UE's path information sent by the UE according to transmission parameters. These transmission parameters include transmission configurations provided by the network device or parameters agreed upon in the protocol. This allows the network device to perform cell handover preparations in advance, based on the UE's path information, before the UE reaches certain cells, enabling rapid and efficient handover between different cells within the network. These cells may include, but are not limited to, terrestrial network cells and / or non-terrestrial cells. The network device can also pre-configure appropriate measurement settings for the terminal device based on this path information.

[0235] In this embodiment, the path information of the UE received by the network device is sent by the UE according to transmission parameters; wherein, the transmission parameters include: transmission configuration provided by the network device, or parameters agreed upon by the protocol. This makes the path information sent by the UE more targeted, ensuring that the path information received by the network device is the information needed by the network device. Since the UE's path information is valid and usable by the network device, the network device can effectively use the UE's path information for UE mobility management. Furthermore, because the path information sent by the UE is the information needed by the network device, the transmission of unnecessary information is reduced, thereby reducing signaling overhead.

[0236] In one embodiment, the method may further include:

[0237] Send a request message to the UE, wherein the request message contains a sending configuration.

[0238] The request information is used to request the UE to send its path information.

[0239] In some examples, the network device can send a request message containing the transmission configuration via a command. This command can be a physical layer command or a higher-layer command. The higher-layer command can be an RRC command or a MAC control element (CE).

[0240] In some examples, the network device may send a UEInformationRequest message containing the transmission configuration to the UE. Correspondingly, the UE may send its path information to the network device via a UEInformationResponse message, based on the transmission configuration.

[0241] In some examples, when the UE is used as a flight device, the network device can receive path information encapsulated in a FlightPathInfoReport sent by the UE according to the transmission parameters.

[0242] In one embodiment, such as Figure 5 As shown, an information transmission method is provided, which is executed by a network device. The method may include the following steps:

[0243] 501: Send a request message to the UE, wherein the request message contains a transmission configuration;

[0244] 502: Receive the path information of the UE sent by the UE according to the transmission configuration.

[0245] In some examples, the sending configuration included in the request message is used to configure one or more alternative reference points.

[0246] In this embodiment, the network device can send a request message to the UE, requesting the UE to report path information. The sending configuration carried in the request message is used to configure one or more alternative reference points. The network device configures one or more alternative reference points for the UE, and the UE reports the path point information of the path point that is closest to the alternative reference point in the planned route, such as the time information and / or location information of the path point with the shortest distance to the alternative reference point.

[0247] In other examples, the sending configuration included in the request message is used to configure one or more alternative reference points and the corresponding threshold values ​​for each alternative reference point.

[0248] In this embodiment, the network device can send a request message to the UE, requesting the UE to report path information. The sending configuration carried in the request message is used to configure one or more alternative reference points and the threshold value corresponding to each alternative reference point. The UE can determine which path point in the UE's movement path and when the distance from the alternative reference point meets the threshold value requirement (e.g., the distance is less than or equal to the threshold value), and report it to the network device and / or the reported path information only contains the path point information that meets the threshold value requirement, such as the time information and / or location information of the path point whose distance from the alternative reference point meets the threshold value requirement.

[0249] In one embodiment, the sending configuration includes:

[0250] Location indication information for one or more alternative reference points, used to indicate the location of one or more alternative reference points.

[0251] For example, the location indication information of the candidate reference point may indicate that the candidate reference point is the current serving cell of the UE. Alternatively, the location indication information of the candidate reference point may indicate that the candidate reference point is a neighboring cell of the current serving cell of the UE.

[0252] In some examples, the location indication information of the alternative reference points includes at least one of the following:

[0253] The index of the alternative reference points;

[0254] The cell identifier of the candidate reference point is used to indicate the cell corresponding to the candidate reference point. The cell is: the UE's current serving cell, the neighboring cell of the current serving cell, or a specific cell.

[0255] The absolute location information of the alternative reference points.

[0256] In some examples, the index of the alternative reference point can be the number of the alternative reference point, which can be, for example, a numeric number.

[0257] The cell identifier of the candidate reference point is used to identify the cell corresponding to the candidate reference point. In some examples, the cell corresponding to the candidate reference point may include the UE's serving cell, neighboring cells, or a specific cell.

[0258] In some examples, the absolute location information of the candidate reference point may include its absolute longitude and absolute latitude. In some examples, the absolute location information of the candidate reference point may also include its absolute altitude.

[0259] In this embodiment, the transmission configuration provided by the network device to the UE includes location indication information of one or more alternative reference points. In this way, the UE can transmit the UE's path information based on the location indication information of one or more alternative reference points.

[0260] For example, the UE can determine the location of one or more alternative reference points based on the location indication information of one or more alternative reference points, and send the path point information of the path point in the UE's movement path that is closest to the location of each alternative reference point.

[0261] In one embodiment, the path information includes: path point information of one or more first path points;

[0262] The first path point is the path point with the shortest distance to the target reference point among one or more path points that the UE plans to pass through; wherein the target reference point is one of the candidate reference points.

[0263] In some examples, there can be one or more target reference points that are closest to the first path point. For example, if a path point is located between two candidate reference points in the path points that the UE plans to traverse, and the path point is closest to each of the two candidate reference points, then the path point can be determined as the first path point.

[0264] In other examples, there can be one or more first path points that are closest to the same target reference point. For example, among the path points that the UE plans to traverse, if there is an alternative reference point between two path points, and the alternative reference point is closest to each of the two path points, then the alternative reference point is used as the target reference point, and both path points are determined to be first path points.

[0265] For example, the distance between the path point and the alternative reference point is the distance in three-dimensional space.

[0266] In this embodiment, for each candidate reference point for which a configuration instruction is sent, the UE selects the path point with the shortest distance to the candidate reference point as the first path point and sends path information containing the path point information of the first path point.

[0267] In one embodiment, the path point information of the first path point includes at least one of the following:

[0268] Location information of the first path point;

[0269] The time information of the UE's planned passage through the first path point;

[0270] The path point index of the first path point;

[0271] The location indication information of the target reference point with the shortest distance to the first path point;

[0272] The relative position information between the first path point and the target reference point.

[0273] For example, time information may include timestamps, which include timestamps describing the path points that the UE is scheduled to traverse.

[0274] In some examples, the time information can be absolute time information (AbsoluteTimeInfo).

[0275] The Information Element (IE) AbsoluteTimeInfo represents absolute time, formatted as YY-MM-DD HH:MM:SS, and encoded using BCD (binary-encoded decimal). The first or leftmost bit of the bit string represents the highest bit of the absolute time, and so on.

[0276] In some examples, location information can be represented by CommonLocationInfo.

[0277] The CommonLocationInfo element is used to transmit detailed location information available on the UE to correlate measurement values ​​with UE location information.

[0278] In other examples, location information can be represented by LocationCoordinates.

[0279] In some examples, the location information of the first waypoint is used to indicate the flight position of the UE when it plans to pass through the first waypoint.

[0280] For example, the location information of the first path point can be location information in three-dimensional space, which may include longitude information, latitude information and altitude information.

[0281] In some examples, the time information for when the UE plans to pass through the first waypoint can be a timestamp. For example, the timestamp when the UE arrives at the first waypoint.

[0282] In some examples, the path point index of the first path point is used to identify the first path point that the UE plans to traverse.

[0283] The path point index can be a path point number. For example, the path point number can be a number sequentially numbered for the path points the UE will traverse according to the plan. Alternatively, the path point number can be a number sequentially numbered for the path points the UE will traverse according to the plan. It is worth noting that the path point index can also be a random number, as long as it uniquely represents a path point; this embodiment does not impose specific limitations on this.

[0284] In some examples, the location indication information of the target reference point may include at least one of the following:

[0285] The index of the target reference point;

[0286] The cell identifier of the target reference point is used to indicate the cell corresponding to the target reference point. The cell is: the UE's current serving cell, the neighboring cell of the current serving cell, or a specific cell.

[0287] The absolute position information of the target reference point.

[0288] In some examples, the relative position information between the first path point and the target reference point can be generated based on the position information of the first path point and the absolute position information of the target reference point.

[0289] In some examples, the relative position information between the first waypoint and the target reference point may include relative longitude and relative latitude. In some examples, the relative position information may also include relative altitude.

[0290] In one embodiment, the sending configuration includes:

[0291] Location indication information for one or more alternative reference points;

[0292] One or more first threshold values;

[0293] Different alternative reference points correspond to the same or different first threshold values.

[0294] In some examples, all alternative reference points can correspond to the same first threshold value. In other examples, different alternative reference points can correspond to different first threshold values. That is, the field corresponding to the first threshold value can be a general value that applies to all configured alternative reference points, or the first threshold value can be configured separately for each alternative reference point.

[0295] In other examples, a portion of the candidate reference points may be configured with the same first threshold value, while different candidate reference points in another portion may be configured with different first threshold values.

[0296] In some examples, an alternative reference point may correspond to the current serving cell, and the alternative reference point and its corresponding threshold value are used to indicate the coverage area of ​​the current serving cell. Alternatively, an alternative reference point may correspond to a neighboring cell, and the alternative reference point and its corresponding threshold value are used to indicate the coverage area of ​​the neighboring cell.

[0297] In one embodiment, the path information includes: path point information of one or more second path points;

[0298] The second path point is: among one or more path points that the UE plans to pass through, the path point whose distance to the candidate reference point meets a first preset condition; wherein, the first preset condition is associated with the first threshold value.

[0299] In some examples, the UE can determine, for each candidate reference point, a path point whose distance from the candidate reference point satisfies a first preset condition among one or more path points that the UE plans to traverse.

[0300] In one embodiment, the distance between the second path point that the UE plans to traverse and one or more of the alternative reference points is less than or equal to the corresponding first threshold value;

[0301] or,

[0302] The distance between the second path point that the UE plans to pass through and the nearest alternative reference point is greater than or equal to the corresponding first threshold value;

[0303] or,

[0304] The distance between the second path point that the UE plans to pass through and the previous path point adjacent to the second path point and the same alternative reference point, respectively, is greater than the corresponding first threshold value, and the other is less than or equal to the corresponding first threshold value.

[0305] or,

[0306] The distance between the second path point that the UE plans to pass through and the next path point adjacent to the second path point and the same alternative reference point, respectively, is greater than the corresponding first threshold value, and less than or equal to the corresponding first threshold value.

[0307] In some examples, for each candidate reference point, the UE can determine the path point whose distance from the candidate reference point is less than or equal to a first threshold value corresponding to the candidate reference point among one or more path points that the UE plans to traverse as the first path point.

[0308] In this embodiment, the number of candidate reference points whose distance to a certain second path point is less than or equal to the corresponding first threshold value can be one or more.

[0309] For example, if a path point is located within the cell coverage area of ​​a candidate reference point (determined by the first threshold value corresponding to the candidate reference point), the path point can be used as a second path point.

[0310] For example, if a path point is located within the overlapping coverage area of ​​different candidate reference points (the cell coverage area of ​​each candidate reference point is determined by the first threshold value corresponding to each candidate reference point), the path point can be used as a second path point.

[0311] For example, if a path point is located between candidate reference point A and candidate reference point B, and the distance between the path point and candidate reference point A is less than or equal to the first threshold value corresponding to candidate reference point A, and the distance between the path point and candidate reference point B is less than or equal to the first threshold value corresponding to candidate reference point B, then the path point is used as the second path point, and the path point information of the second path point is included in the path information reported to the network device.

[0312] In some examples, for each candidate reference point, the UE can determine the path point that the UE plans to pass through that candidate reference point is closest to that candidate reference point. If the distance between the determined path point and the candidate reference point is greater than or equal to the first threshold value corresponding to the candidate reference point, then the path point is used as the second path point, and the path point information of the second path point is included in the path information reported to the network device.

[0313] In some examples, for each candidate reference point, the UE can determine the path point that the UE plans to traverse, whose distance from the candidate reference point is less than or equal to the first threshold value corresponding to the candidate reference point.

[0353] In some examples, when the distance between the third path point and the current position of the UE is less than or equal to the second threshold value, the distance between the third path point and the current position of the UE satisfies the second preset condition.

[0354] In other examples, when the distance between the third path point and the current position of the UE is greater than the second threshold value, the distance between the third path point and the current position of the UE satisfies the second preset condition.

[0379] This disclosure provides an information transmission method, which may include:

[0380] The network device is configured with a reference location, and the UE reports the time and location of the path point closest to the reference location.

[0381] In some examples, the network device configures reference locations, including sending a request message to the UE requesting the UE to report flight path information, wherein the request message may carry one or more reference locations.

[0382] In some examples, each reference location may correspond to the current serving cell or a neighboring cell.

[0384] In some examples, when the UE receives a request from the network device, the UE reports flight path information, including: path point information with the shortest distance to the reference position indicated by the network device, wherein the path point information may include: timestamp and / or location information.

[0385] In some examples, the UE may report only the path point that is closest to the reference location or report flight path information that includes the path point information.

[0386] In some examples, the UE may indicate in the flight path information which waypoints are the shortest pathpoints to the reference location, and / or indicate the corresponding reference location, for example, indicating the index or cell identifier corresponding to the reference location.

[0387] In some examples, the network side receives flight path information reported by the UE.

[0388] Example 2

[0389] This disclosure provides an information transmission method, which may include:

[0390] The network device configures reference locations and threshold values. The UE determines when the distance between its flight path and the reference location is greater than or less than the threshold value based on the flight path and reports it to the network device. And / or, the reported flight path information only includes path point information that meets the threshold value requirements.

[0391] In some examples, configuring a reference location and a threshold value for a network device may include: the network device sending a request message to the UE requesting the UE to report flight path information, the request message of which may carry a reference location and a threshold value.

[0392] In some examples, the reference location may correspond to the current serving cell, and the reference location and threshold value are used to indicate the coverage area of ​​the current serving cell. Alternatively, the reference location may correspond to a neighboring cell, and the reference location and threshold value are used to indicate the coverage area of ​​a particular cell.

[0397] The flight path information reported by the UE includes: the time and / or the corresponding location when the distance from the reference position changes from less than or equal to a threshold value to greater than the threshold value.

[0398] In some examples, the flight path information reported by the UE includes the duration for which the distance between the UE's flight path and the reference location meets a threshold value.

[0399] In some examples, the UE can indicate in the flight path information which waypoints first meet the threshold requirements, for example, by indicating the index of the waypoint.

[0400] In some examples, network devices can also be configured with multiple reference locations and reference thresholds.

[0401] In some examples, if the network device is supported in indicating multiple reference locations and thresholds, each reference location and threshold can correspond to an index or cell identifier.

[0402] In some examples, the UE can report the information described in section 3 for each reference location and corresponding threshold value, which may include the index or cell identifier corresponding to these reference locations and thresholds.

[0403] In some examples, the network side receives flight path information reported by the UE.

[0404] Example 3

[0405] This disclosure provides an information transmission method, which may include:

[0406] The UE reports average path information, informing network devices of the time interval or distance interval between different path points.

[0409] Location information corresponding to each path point;

[0413] In some examples, in response to a request from the network device, the UE determines the distance between adjacent waypoints in the flight path information to be reported, and then reports the flight path information, which includes one or more of the following:
