[0002] For mobile terminals such as drones, cars and mobile robots, they often have route planning requirements due to their mobile characteristics. Take drones as an example. Due to their high efficiency and convenience, drones are widely used in many fields, such as aerial photography, agricultural plant protection, etc. When using drones, the drone's navigation route can be controlled by real-time control. It is also possible to use pre-planned routes to make the drone fly along the planned routes.

[0094] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0095] In order to better understand the technical solution of the embodiment of the present disclosure, take a drone as an example to illustrate the flight scene of the drone: see Figure 1 , the drone flies according to the preset route, passing through areas A, B, and C in turn. At this time, there are fewer terminals in areas A, B, and C, so there will be no congestion. Figure 2 , the drone continues to fly along the preset route. When it flies to area B, a large number of flight terminals appear in area C. At this time, area C is already congested. If the drone continues to fly along the preset route without knowing the congestion in area C, the problem of unsmooth navigation will occur. The disclosed embodiment is a technical solution proposed for the above scenario.

[0096] like Figure 3 As shown, an embodiment of the present disclosure provides a method for collecting information, which is applied to a first terminal and includes the following steps:

[0097] Step 31, receiving control information of the event;

[0098] Here, the first terminal may be a mobile terminal such as a car, train, drone, robot, etc. It may also be a mobile terminal carried by a car, train, drone, robot, etc. Here, the control information of the event may be information for controlling the first terminal to report information to the network device when the event occurs. The network device in the present disclosure includes at least one of a control device, a base station, a transmitting point, a receiving point, a central unit (central RAN unit), a distributed unit (distributed RAN unit), a baseband processing unit (BBU, Building Baseband Unit), a relay, a communication balloon, a flying aircraft base station, an antenna, and a satellite. The event may be an event corresponding to the detection that the sum of the transmit powers of the reference signals sent by N other terminals is greater than the first threshold value; the event may also be an event corresponding to the detection of an obstacle and / or an obstacle state that hinders the movement or communication of the first terminal. The first terminal may receive the control information of the event at startup. The first terminal may receive the control information of the event by request; or it may passively receive the control information of the event sent by a network device such as a base station. Here, it may also be that the network device actively sends the control information of the event to the first terminal every time the first terminal passes through an area. The control information can be used to set different events and control information of the events according to different regions.

[0099] Step 32, based on the control information, when a first event is detected that the sum of the transmission powers of reference signals sent by N other terminals is greater than a first threshold value, and / or when a second event of an obstacle and / or an obstacle state that hinders the movement or communication of the first terminal is detected, first information is sent to the first network node; wherein N is a natural number greater than or equal to 1.

[0100] The other terminals mentioned here can be mobile terminals such as cars, trains, drones, robots, etc. It can also be a mobile terminal carried by cars, trains, drones, robots, etc. Here, the resource position where the other terminals send the reference signal does not perform data scheduling and signaling, so that the measurement of the reference signal is more accurate. The first network node is a network device, and the first network node can be one of the following: control equipment, base station, transmission point, receiving point, central unit (central RAN unit), distributed unit (distributed RAN unit), baseband processing unit (BBU, Building Baseband Unit), relay, communication balloon, flying aircraft base station, antenna, satellite, etc. At least one. Here, in a set regional wireless communication system or in all wireless communication systems, the network device assigns reference signals with the same characteristics to the first terminal and the other terminals. Among them, the reference signals have the same characteristics, including: the reference signals have the same time domain position; and / or, the reference signals have the same frequency domain position; and / or, the reference signals have the same spatial domain position; and / or, the reference signals have the same code sequence.

[0101] Here, the first terminal may detect the transmit power of the reference signal sent by the other terminal including the specified code sequence at the specified time domain and frequency domain position.

[0102] Here, the first terminal may detect the transmit power of the reference signal sent by the other terminals in the adjacent area or position according to a set period or at a set time point; or the first terminal may detect the transmit power of the reference signal sent by the terminal in the adjacent area every time it moves a set distance. Here, the other terminals may transmit the reference signal periodically. Here, the greater the transmit power, the more other terminals there are, and the greater the traffic of the other terminals in the area where the reference signal is received.

[0103] Here, the first terminal may also send the reference signal when not detecting the reference signal sent by the other terminal.

[0104] Here, for the first terminal capable of simultaneously transmitting and receiving, the reference signal may be transmitted while receiving and detecting reference signals transmitted by other terminals.

[0105] Here, the obstacle may be a building, a mountain, a river, etc., and the obstacle may be detected by an ultrasonic sensor. The obstacle state may be wind speed, humidity, visibility, etc., and the obstacle state may also be detected based on sensing technology. For example, infrared sensing technology, image sensing technology, temperature sensing technology, etc. Specifically, humidity may be detected by a humidity sensor, and visibility may be detected by a light sensor. The first network node may be a base station that communicates with the first terminal, or may be a network device that performs route planning for the first terminal.

[0106] Here, the first threshold value can be flexibly set according to demand. For example, when the first terminal is sailing in an area where other terminals appear frequently and densely for a long time, a larger first threshold value can be set; when the first terminal is sailing in an area where other terminals appear seldom, a smaller first threshold value can be set;

[0107] In the embodiment of the present disclosure, on the one hand, the first terminal can detect the reference signal of the reference signal sent by N other terminals, and it can be determined that the N other terminals appear in the vicinity of the first terminal. When the sum of the transmit powers of the reference signals sent by the N other terminals is large, it can be determined that there are many other terminals near the first terminal. In this way, when the first terminal detects that the sum of the transmit powers of the reference signals sent by the N other terminals is greater than the first threshold value, at this time, there are relatively many other terminals near the first terminal, and it can be determined that congestion will occur in the vicinity. On the other hand, when a second event of an obstacle and / or an obstacle state that hinders the movement or communication of the first terminal is detected, at this time, an obstacle and / or an obstacle state that hinders the movement or communication of the first terminal appears near the first terminal, which will cause the movement and communication of the first terminal; when the first event and / or the second event occurs, the first information is sent to the first network node in real time, so that the first network node can obtain the first information in real time. Taking drone route planning as an example, after the first terminal sends the first information to the control terminal of the drone, the control terminal will adjust the drone route based on the first information received, so that the first terminal can adjust the route in time to avoid congested areas where a large number of other terminals appear, ensuring smooth navigation of the first terminal.

[0108] Wherein, in step 32, when detecting a first event that the sum of transmit powers of reference signals sent by N other terminals is greater than a first threshold value, sending first information to the first network node includes:

[0109] When a first event is detected that the sum of transmit powers of reference signals sent by N other terminals in the same cell is greater than a first threshold value, sending first information to the first network node;

[0110] or, when a first event is detected that the sum of transmit powers of reference signals sent by N other terminals in a cell of the same frequency band is greater than a first threshold value, sending first information to the first network node;

[0111] or, when a first event is detected in which the sum of the transmit powers of reference signals sent by N other terminals within a preset range is greater than a first threshold value, sending first information to the first network node;

[0112] Wherein, the reference signals have the same characteristics.

[0113] Here, the same cell may be a cell adjacent to the cell where the first terminal is located, or a cell set at a distance from the cell where the first terminal is located. Here, the cell in the same frequency band may be a collection of multiple cells in the same frequency band. The preset range may be a geographically located area range, or a range covered by multiple cells.

[0114] Here, the feature of the reference signal may be a time domain feature, a frequency domain feature, a spatial domain feature, or content information carried by the reference signal. Taking the frequency domain feature as an example, the feature of the reference signal may be the frequency of the reference signal. Taking the content information carried by the reference signal as an example, the feature of the reference signal may be the code information carried by the reference signal, for example, the code feature information carried by the reference signal is 00010.

[0115] Here, the reference signals having the same characteristics may be reference signals having the same frequency, or may be reference signals carrying the same code sequence. Reference signals with different characteristics may be characteristic signals having different frequencies, or may be reference signals carrying different code sequences. Here, different characteristics can distinguish which cell or area the reference signal is sent from, for example, a reference signal with a code sequence of 001 is sent from cell A, a reference signal with a code sequence of 002 is sent from cell B, and a reference signal with a code sequence of 003 is sent from cell C. In this way, the other terminals can screen and accurately detect the corresponding reference signal transmission power in each cell or area.

[0116] The reference signals have the same characteristics, including:

[0117] The reference signals have the same time domain position;

[0118] And / or, the reference signals have the same frequency domain position;

[0119] And / or, the reference signals have the same spatial position;

[0120] And / or, the reference signals have the same code sequence.

[0121] Here, the reference signals having the same frequency domain position may mean having the same frequency; the reference signals having the same time domain position may mean being sent at the same time; the reference signals having the same spatial domain position may mean being sent at the same spatial position; and the reference signals having the same code sequence may mean carrying the same digital information. For example, both carry a code sequence with data information of 001.

[0122] Here, the same features can be that multiple features in the time domain position, frequency domain position, spatial domain position and code sequence are the same. For example, if the time-frequency domain position and code sequence of the reference signal are the same, the transmit power of the reference signal with the same time-frequency domain position and code sequence sent by the terminal in the adjacent cell is detected at the same time. Since the reference signal needs to have the same time-frequency position and code sequence at the same time, the required reference signal can be accurately screened out, and the interference signal in the space (such as the interference signal whose time-frequency domain position is consistent with the time-frequency domain position of the reference signal to be measured) will not be detected at the same time, which will affect the detection result.

[0123] Among them, the first information includes at least one of the following: event type information, information on the location of the first terminal, information on the locations of the other terminals, obstacle information within a preset threshold range of the first terminal, transmission power information of the reference signal, time information for sending the first information, and effective duration information of the first information.

[0124] Here, when a first event is detected in which the sum of the transmission powers of reference signals sent by N other terminals is greater than a first threshold value, the event type information includes first event information; when a second event is detected in which an obstacle and / or obstacle state that hinders the movement or communication of the first terminal is detected, the event type information includes second event information.

[0125] Here, the information of the location of the first terminal includes at least one of the following: the longitude and latitude coordinate information of the first terminal, and the 3D / 2D grid unit information of the first terminal in the grid map. Here, the longitude and latitude coordinate information of the first terminal includes information of the geographical location of the first terminal expressed by longitude and latitude; the 3D / 2D grid unit information may be a specific geographical location mapped by a grid unit in a grid map, and the grid unit in the grid map is a grid unit area that pre-divides the coverage area within a cell according to the geographical area covered by the network.

[0126] Here, the grid unit is: The spatial grid should grid and encode the entire three-dimensional space of the earth. The sphere is recursively divided at certain intervals in the three dimensions of longitude, latitude, and altitude, with the advantages of longitude and latitude consistency and orthogonality. The grid has the advantages of being identifiable, locatable, indexable, multi-scale, and automatically spatially associated, and can be used as a spatial reference framework for spatial control and big data management. The voxels of the spatial grid are multi-scale, and the voxels of each scale are seamless and non-overlapping, filling the entire three-dimensional space of the earth.

[0127] Wherein, the method further comprises:

[0128] Step 33, receiving route adjustment information determined based on the first information;

[0129] Step 34, adjusting the route of the first terminal based on the route adjustment information; the adjusting the route of the first terminal includes: adjusting the preset first route to a second route that does not pass through the location area of ​​the other terminals.

[0130] The preset first route may be a route preset when the first terminal, such as a drone, takes off. Here, the preset first route may be a route planned by a network device end (such as a base station) based on the route planning information between the location and the destination sent by the first terminal. Here, the route planning information includes the location information, destination information, obstacle information, etc. of the first terminal. Here, the base stations of different cells may share the relevant information of the route. The first terminal may learn from the base station of the cell where it is located that the route passes through the cell. For example, the first terminal may learn from the base station that the route passes through cell A, cell B, and cell C in sequence.

[0131] Here, the route adjustment information includes path information of the first terminal moving along the adjusted route, information of the cells passed through, etc. Adjusting the route of the first terminal may be changing the original route and moving along the adjusted route.

[0132] Wherein, the method further comprises:

[0133] Receiving mapping relationship table information sent via broadcast messages and / or dedicated signaling;

[0134] The first information is determined based on the mapping relationship table information; wherein the mapping relationship table information includes:

[0135] Mapping relationship table information between geographic locations and grid cells in a grid map;

[0136] and / or, mapping relationship table information between reference signal received power values ​​and angles between reference positions;

[0137] and / or, mapping relationship table information between heights and grid cells in a grid map;

[0138] And / or, mapping relationship table information between delay values ​​and angles of reference positions.

[0139] Here, after the first terminal receives the mapping relationship table information sent through the broadcast message and / or the dedicated signaling, it can quickly determine the required information based on the mapping relationship table information. For example, when it is necessary to obtain the reference signal received power value, after knowing the angle of the reference position, it is possible to quickly query the reference signal received power value of the corresponding angle based on the mapping relationship table of the reference signal received power value and the angle of the reference position, which is more efficient than obtaining the reference signal received power value through a complex calculation process.

[0140] like Figure 4 As shown, another embodiment of the present disclosure provides a method for collecting information, which is applied to a network node and includes the following steps:

[0141] Step 41, sending control information of the event to the first terminal;

[0142] Here, the first terminal may be a mobile terminal such as a car, train, drone, robot, etc. It may also be a mobile terminal carried by a car, train, drone, robot, etc. Here, the network node may be a network device, and the network device in the present disclosure includes at least one of a control device, a base station, a transmitting point, a receiving point, a central unit (central RAN unit), a distributed unit (distributed RAN unit), a baseband processing unit (BBU, Building Baseband Unit), a relay, a communication balloon, a flying aircraft base station, an antenna, and a satellite. Here, the control information of the event may be information for controlling the first terminal to report information to the network device when the event occurs. The event may be an event corresponding to the detection that the sum of the transmit powers of the reference signals sent by N other terminals is greater than the first threshold value; the event may also be an event corresponding to the detection of an obstacle and / or an obstacle state that hinders the movement or communication of the first terminal. The network node may be control information for sending an event at startup. The network node may be control information for sending an event by receiving a request; or it may be control information for actively sending an event. Here, it may also be that each time the first terminal passes through an area, the network node enters the network device and actively sends control information for the event to the first terminal. The control information can be used to set different events and control information of the events according to different regions.

[0143] Step 42, receiving the first information sent by the terminal; wherein, when a first event is detected that the sum of the transmission powers of reference signals sent by N other terminals is greater than a first threshold value, and / or when a second event of an obstacle and / or an obstacle state that hinders the movement or communication of the first terminal is detected, the first information includes information sent by the first terminal based on the control information; wherein N is a natural number greater than or equal to 1.

[0144] The other terminals described here may be mobile terminals such as cars, trains, drones, robots, etc. It may also be a mobile terminal carried by cars, trains, drones, robots, etc. Here, the resource location where the other terminals send the reference signal does not perform data scheduling and signaling. Here, the reference signals in different areas may have different identification features, and the first terminal can filter out the required reference signals based on the identification features after receiving the reference signals in the space. For example, if the identification code corresponding to the reference signal in cell A is 001, the first terminal will filter out the reference signal with the identification code of 001 in the space and detect its transmit power. Here, it may be to detect the transmit power of the reference signal sent by the terminal in the adjacent area (for example, in the adjacent cell) according to the set period or to detect the transmit power of the reference signal sent by the terminal in the adjacent area (for example, in the adjacent cell) every time the first terminal moves a set distance. Here, the other terminals may be periodically transmitting the reference signal. Here, the greater the transmit power, the more other terminals are represented.

[0145] Here, the obstacle may be a building, a mountain, a river, etc., and the obstacle may be detected by an ultrasonic sensor. The obstacle state may be wind speed, humidity, visibility, etc., and the obstacle state may be detected based on sensing technology. For example, infrared sensing technology, image sensing technology, temperature sensing technology, etc. Specifically, humidity may be detected by a humidity sensor, and visibility may be detected by a light sensor. The first network node may be a base station that communicates with the first terminal, or a network device that performs route planning for the first terminal.

[0146] Here, the first threshold value can be flexibly set according to demand. For example, when the first terminal is sailing in an area where other terminals appear frequently and densely for a long time, a larger first threshold value can be set; when the first terminal is sailing in an area where other terminals appear seldom, a smaller first threshold value can be set;

[0147] In the disclosed embodiment, when the first terminal detects that the sum of the transmission powers of the reference signals sent by N other terminals is greater than the first threshold value, at this time, a relatively large number of the other terminals appear near the first terminal, which will cause congestion; when the first terminal detects a second event of an obstacle and / or an obstacle state that hinders the movement or communication of the first terminal, at this time, an obstacle and / or an obstacle state that hinders the movement or communication of the first terminal appears near the first terminal, which will cause the movement and communication of the first terminal; when the first event and / or the second event occurs, the first information is sent to the first network node in real time to facilitate the first network node to obtain the first information in real time. Taking the drone route planning as an example, after the first terminal sends the first information to the drone's control terminal, the control terminal will adjust the drone route based on the received first information, so that the first terminal can adjust the route in time to bypass the congested area where a large number of the other terminals appear, and ensure the smooth navigation of the first terminal.

[0148] Wherein, the method further comprises:

[0149] Configuring reference signals with the same characteristics for terminals in the same cell;

[0150] Or, configuring reference signals with the same characteristics for terminals in a cell of the same frequency band;

[0151] Or, configure reference signals with the same characteristics for terminals within a preset range.

[0152] Here, the same cell may be a cell adjacent to the cell where the first terminal is located, or a cell set at a distance from the cell where the first terminal is located. Here, the cell in the same frequency band may be a collection of multiple cells in the same frequency band. The preset range may be a geographically located area range, or a range covered by multiple cells.

[0153] Here, the feature of the reference signal may be a time domain feature, a frequency domain feature, or content information carried by the reference signal. Taking the frequency domain feature as an example, the feature of the reference signal may be the frequency of the reference signal. Taking the content information carried by the reference signal as an example, the feature of the reference signal may be the code information carried by the reference signal, for example, the code feature information carried by the reference signal is 00010.

[0154] Here, the reference signals having the same characteristics may be reference signals having the same frequency, or may be reference signals carrying the same code sequence. Reference signals with different characteristics may be characteristic signals having different frequencies, or may be reference signals carrying different code sequences. Here, different characteristics can distinguish which cell or area the reference signal is sent from, for example, a reference signal with a code sequence of 001 is sent from cell A, a reference signal with a code sequence of 002 is sent from cell B, and a reference signal with a code sequence of 003 is sent from cell C. In this way, the other terminals can screen and accurately detect the corresponding reference signal transmission power in each cell or area.

[0155] The configuration of the reference signals having the same characteristics includes:

[0156] configuring reference signals having the same time domain position;

[0157] and / or, configuring reference signals having the same frequency domain position;

[0158] and / or, configuring reference signals having the same spatial location;

[0159] And / or, configuring a reference signal having the same code sequence.

[0160] Here, the reference signals having the same frequency domain position may mean having the same frequency; the reference signals having the same time domain position may mean being sent at the same time; the reference signals having the same spatial domain position may mean being sent at the same spatial position; and the reference signals having the same code sequence may mean carrying the same digital information. For example, both carry a code sequence with data information of 001.

[0161] Here, the same features can be that multiple features in the time domain position, frequency domain position, spatial domain position and code sequence are the same. For example, if the time-frequency domain position and code sequence of the reference signal are the same, the transmit power of the reference signal with the same time-frequency domain position and code sequence sent by the terminal in the adjacent cell is detected at the same time. Since the reference signal needs to have the same time-frequency position and code sequence at the same time, the required reference signal can be accurately screened out, and the interference signal in the space (such as the interference signal whose time-frequency domain position is consistent with the time-frequency domain position of the reference signal to be measured) will not be detected at the same time, which will affect the detection result.

[0162] Wherein, the method further comprises:

[0163] Step 43, adjusting the route of the first terminal based on the first information; wherein the adjusting the route of the first terminal includes: adjusting the preset first route to a second route that does not pass through the location area of ​​the other terminal;

[0164] Step 44: sending route adjustment information for adjusting the route of the first terminal to the terminal.

[0165] Here, adjusting the route of the first terminal based on the first information may be inputting the first information into a neural network algorithm model to determine an updated route of the first terminal.

[0166] The preset first route may be a route preset when the first terminal, such as a drone, takes off. Here, the preset first route may be a route planned by a network device end (such as a base station) based on the route planning information between the location and the destination sent by the first terminal. Here, the route planning information includes the location information, destination information, obstacle information, etc. of the first terminal. Here, the base stations of different cells may share the relevant information of the route. The first terminal may learn from the base station of the cell where it is located that the route passes through the cell. For example, the first terminal may learn from the base station that the route passes through cell A, cell B, and cell C in sequence.

[0167] Here, the route adjustment information includes path information of the first terminal moving along the adjusted route, information of the cells passed through, etc. Adjusting the route of the first terminal may be changing the original route and moving along the adjusted route.

[0168] Wherein, the method further comprises:

[0169] Sending mapping relationship table information to the terminal through a broadcast message and / or dedicated signaling; wherein the mapping relationship table information includes:

[0170] Mapping relationship table information between geographic locations and grid cells in a grid map;

[0171] and / or, mapping relationship table information between reference signal received power values ​​and angles between reference positions;

[0172] and / or, mapping relationship table information between heights and grid cells in a grid map;

[0173] And / or, mapping relationship table information between delay values ​​and angles of reference positions.

[0174] Here, after the first terminal receives the mapping relationship table information sent through the broadcast message and / or the dedicated signaling, it can quickly determine the required information based on the mapping relationship table information. For example, when it is necessary to obtain the reference signal received power value, after knowing the angle of the reference position, it is possible to quickly query the reference signal received power value of the corresponding angle based on the mapping relationship table of the reference signal received power value and the angle of the reference position, which is more efficient than obtaining the reference signal received power value through a complex calculation process.

[0175] In order to more conveniently understand the embodiments of the present disclosure, the technical solution of the present disclosure is further described below through two examples:

[0176] Example 1: See Figure 5 Another embodiment of the present disclosure provides a method for collecting information, which is applied to a drone. The method includes:

[0177] Step 51: The drone obtains the preset route information and event control information of the first terminal from the network device. The preset route information includes the cells that need to be passed through when navigating according to the preset route and the time-frequency domain position and carried code sequence information of the reference signal allocated to the terminal by the network device in different cells. Here, the time-frequency domain position and the carried code sequence of the reference signal in the same cell are the same. The control information of the event includes sending a first information to the first network node when a first event is detected that the sum of the transmission powers of the reference signals sent by N other terminals is greater than a first threshold value, and / or when a second event is detected that an obstacle and / or an obstacle state that hinders the movement or communication of the first terminal is detected.

[0178] Step 52: The UAV navigates according to a preset route and detects the transmission power of reference signals having the same time-frequency domain position and carrying the same code sequence sent by other terminals in an adjacent cell (first adjacent cell), wherein the adjacent cell is on the route of the UAV and is a neighboring cell of the cell where the UAV is located.

[0179] Step 53: When the sum of the transmission powers in the adjacent cells is greater than the first threshold value, first information for planning the route of the drone is sent to the control end. Here, the first information includes coordinate information of the location of the drone, obstacle information around the location of the drone, and power information of reference signals of neighboring cells of the cell where the drone is located.

[0180] Step 54: Receive the route adjustment information determined based on the first information and sent by the control end, and adjust the preset route passing through the first neighboring area to a route passing through the second neighboring area based on the route adjustment information, wherein the sum of the transmission powers of the terminals in the first neighboring area is greater than the sum of the transmission powers of the terminals in the second neighboring area.

[0181] In this example, when the sum of the transmission powers in the adjacent cells is greater than the first threshold value, that is, the number of terminals in the adjacent cells is relatively large and congestion occurs, the drone sends a first message to the control terminal, and the control terminal adjusts the route based on the first information so that the drone can adjust the route in time to bypass the congested cell and ensure smooth navigation of the first terminal.

[0182] Example 2: See Figure 6Another embodiment of the present disclosure provides an information collection method, which is applied to a network device, and the method includes:

[0183] Step 61: The network device sends the preset route information and control information of the event to the drone. The preset route information includes the cells that the drone needs to pass through when navigating according to the preset route, and the time-frequency domain position and carried code sequence information of the reference signal allocated to the terminal by the network device in different cells. Here, the time-frequency domain position and the carried code sequence of the reference signal in the same cell are the same. The control information of the event includes sending a first information to the first network node when a first event is detected that the sum of the transmission powers of the reference signals sent by N other terminals is greater than a first threshold value, and / or when a second event is detected that an obstacle and / or an obstacle state that hinders the movement or communication of the first terminal is detected.

[0184] Step 62: The network device sends configuration information for the terminal entering the cell to generate a reference signal having the same time-frequency domain position and code sequence.

[0185] Step 63: Receive the first information sent by the drone when the sum of the transmission powers of reference signals of other terminals in an adjacent cell is greater than a first threshold value, wherein the adjacent cell is on the route of the drone and is a neighboring cell of the cell where the drone is located.

[0186] Step 64: Determine to adjust the route based on the first information, and send the route adjustment information to the UAV.

[0187] In this example, when the sum of the transmission powers in the adjacent cells is greater than the first threshold value, that is, the number of other terminals in the adjacent cells is relatively large and congestion occurs, the drone sends a first message to the control terminal, and the control terminal adjusts the route based on the first information so that the drone can adjust the route in time to bypass the congested cell and ensure smooth navigation of the first terminal.

[0319] The following takes the time sensitive control (TSC) service as an example and further illustrates it through a specific embodiment:

[0320] Another embodiment of the present disclosure provides an information collection method, which is applied to a network device, including:

[0321] Step a: The network device (such as a base station) receives auxiliary information of the TSC service of the terminal (such as a drone, a robotic arm, etc.) sent by the core network. Here, the auxiliary information may be sent to the network device at the granularity of the quality of service flow Qos flow.

[0322] The auxiliary information of TSC reflects the characteristics of TSC services. It can be sent by the core network to the base station during the establishment and / or reconfiguration of a service quality flow. Obtaining the characteristics of the TSC service can help the base station to more effectively utilize the configured grant (Configured grant) / semi-permanent scheduling SPS (Semi-Persistent Scheduling) / dynamic scheduling to schedule periodic and determined service flows. The auxiliary information can be notified to the wireless access network node by the core network, for example, the network management, the application server or / and by the terminal. Among them, the maximum value of the TSC data burst size (TSC Burst Size) will correspond to the maximum data burst volume MDBV (MDBV, Maximum Data Burst Volume) of the 5G quality indication 5QI, that is, the MDBV is greater than or equal to 5QI.

[0323] Step b: configuring wireless resources for the terminal according to the auxiliary information to send and / or receive data / signaling. The auxiliary information includes auxiliary information of one or more service quality flows;

[0324] A QoS flow may be composed of multiple streams with similar QoS characteristics, and the arrival time of these services may be different. Here, the specific form of the auxiliary information of each QoS flow QoS flow provided by the core network to the base station may be composed of auxiliary information of one or more service streams; wherein the auxiliary information includes at least one of the following information:

[0325] the life cycle of the business;

[0326] The arrival time of the service;

[0327] the survival time of the business;

[0328] The maximum length of the data of the service;

[0329] The maximum value of the data burst size of the service;

[0330] The average length of the service packets;

[0331] The minimum length of the service packet that needs to be guaranteed;

[0332] One or more slice numbers / identifiers;

[0333] Service quality QoS information.

[0334] In one embodiment, QoS flow1 consists of stream 2, stream 4 and stream 5, and the auxiliary information of QoS flow1 sent by the core network to the base station consists of the auxiliary information of stream 2, stream 4 and stream 5.

[0335] Alternatively, the specific form of the Assistance Information for each QoS flow that the core network sends to the base station may be composed of the service arrival time of one or more service streams; for example, QoS flow1 is composed of stream 2, stream 4 and stream 5, then the auxiliary information of QoS flow1 sent by the core network to the base station is composed of the service cycle, the survival time of the service, the maximum length of the service packet, the average length of the service packet, and / or the minimum length of the service packet that needs to be guaranteed, and at the same time, carries a list of arrival times of the services of stream 2, stream 4 and stream 5.

[0336] In this embodiment, the problem that the wireless access network cannot use the auxiliary information sent by the core network with the granularity of the service quality flow QoSflow to configure wireless resources is solved. For example, if the service arrival time of each thin stream is different and / or the service arrival period of each thin stream is different, the wireless access network cannot confirm which subframe, time slot and / or time symbol is used for the corresponding terminal to configure the resource configuration starting position and / or configuration period of the configured grant / semi-permanent scheduling (SPS, Semi-Persistent Scheduling) / dynamic scheduling. Based on the method of the embodiment of the present disclosure, the wireless access network can use the specific service period of each thin stream in the auxiliary information sent by the core network, the service arrival time, the service survival time, the maximum length of the service data, the maximum value of the service data burst scale, the average length of the service packet, and / or the minimum length of the service packet that needs to be guaranteed to configure the corresponding terminal with the matching resource starting position, resource configuration period, resource occupied time and frequency domain size, resource modulation and coding strategy, etc. of the grant (Configured grant) / semi-permanent scheduling SPS (Semi-Persistent Scheduling).
