Description

Technical Field

[0001] The embodiments of the present application relate to the field of communications, and in particular, to a communication method and device. Background Art

[0002] Drone countermeasure technology refers to the use of a series of technical means such as wireless jamming technology and network patching technology to counter illegal drones. Among them, wireless jamming technology interferes with illegal drones through drone positioning systems or operating radio signals, causing illegal drones to lose control and make forced landings, hover or return.

[0003] In wireless jamming technology, blocking jamming technology, sweeping frequency jamming technology, and aiming frequency jamming technology are usually used to jam illegal drones. However, the jamming efficiency of blocking jamming technology is low; the number of signal sources (such as drones) of aiming frequency jamming technology is limited, that is, when there are many signal sources and frequency bands, and they are dense, illegal drones cannot be detected. Therefore, sweeping frequency jamming technology is currently used more.

[0004] However, the frequency sweep jamming technology will cause interference to legitimate drones within the coverage of the jamming beam. Therefore, how to prevent legitimate drones from being interfered with while jamming illegal drones is an urgent problem to be solved. Summary of the invention

[0005] The present application provides a communication method and device, which can prevent legitimate drones from being interfered with while interfering with illegal drones.

[0006] In a first aspect, a communication method is provided, which can be executed by a first network element, or by a component of the first network element, such as a processor, a chip, or a chip system of the first network element, or by a logic module or software that can implement all or part of the functions of the first network element. The method includes: obtaining location information of a target device; determining a first wireless access network device that interferes with the target device according to the location information of the target device, the target device being within the signal coverage range of the first wireless access network device; and sending first information, the first information indicating that the first terminal device is moved out of the signal coverage range of the first wireless access network device, the first terminal device being a terminal device within the signal coverage range of the first wireless access network device.

[0007] Based on this solution, when the first terminal device and the target device exist simultaneously within the signal coverage of the first wireless access network device, the first wireless access network device that will interfere with the target device can send first information to instruct the first terminal device to be moved out of the signal coverage of the first wireless access network device. Therefore, the first access network device can subsequently interfere with the target device after the first terminal device is moved out of the signal coverage of the first wireless access network device, thereby preventing the first terminal device from being interfered with.

[0008] In one possible design, determining the first terminal device includes: the signal coverage range of the first wireless access network device is the signal coverage range when the first wireless access network device sends a signal according to a first power, and the first power is greater than or equal to the current signal transmission power of the first wireless access network device.

[0009] Based on this possible design, since when the first wireless access network device uses the first power to interfere with the target device, all terminal devices within the signal coverage range when the first wireless access network device sends signals at the first power will be interfered with, the terminal devices within the signal coverage range when the first wireless access network device sends signals at the first power are determined as the first terminal devices, and then the first terminal devices can be migrated out of the signal coverage range of the first wireless access network device to avoid interference to the first terminal device when the first wireless access network device interferes with the target device.

[0010] In one possible design, the communication method also includes: receiving second information indicating that the first terminal device has successfully migrated; and sending third information to the first wireless access network device, the third information indicating that the first wireless access network device interferes with the target device.

[0011] In one possible design, the fourth information also includes first location information, and the first location information indicates the location of the target device after the interference; when the fourth information indicates that the interference fails on the first frequency band, the communication method also includes: determining a third wireless access network device that will interfere with the target device after the interference based on the first location information, and the location of the target device after the interference is within the signal coverage range of the third wireless access network device.

[0012] In a second aspect, a communication method is provided, which can be executed by a first network element, or by a component of the first network element, such as a processor, chip, or chip system of the first network element, or by a logic module or software that can realize all or part of the functions of the first network element. The method includes: obtaining the location information of the target device; determining the first wireless access network device and the second wireless access network device according to the location information of the target device, the target device exists within the signal coverage range of the first wireless access network device, the first wireless access network device will interfere with the target device, the second wireless access network device is a service wireless access network device for the third terminal device, and the third terminal device is within the signal coverage range of the first wireless access network device; sending ninth information, the ninth information instructing the second wireless access network device to request to switch the third terminal device to the first wireless access network device.

[0013] Based on this solution, when the third terminal device and the target device exist simultaneously within the signal coverage of the first wireless access network device, the first network element can instruct the second wireless access network device to switch the third terminal device to the first wireless access network device. Therefore, after the third terminal device accesses the first wireless access network device, the first wireless access network device can learn the time of the communication service of the third terminal device, so that when interfering with the target device, the time of the communication service of the third terminal device can be considered, for example, the target device can be interfered with at other times other than the time of the communication service of the third terminal device, so as to avoid the third terminal device from being interfered with.

[0014] In one possible design, determining a second wireless access network device includes: determining a first interference range based on a first power, the first power being greater than or equal to a current signal transmission power of the first wireless access network device, and the first interference range being a signal coverage range when the first wireless access network device transmits a signal according to the first power; determining, as a third terminal device, a terminal device whose service wireless access network device is not the first wireless access network device among at least one terminal device within the first interference range; and determining the service wireless access network device of the third terminal device as the second wireless access network device.

[0015] Based on this possible design, since the first interference range is determined according to the first power, when the first wireless access network device subsequently uses the first power to interfere with the target device, all terminal devices within the first interference range will be interfered with. Therefore, among the terminal devices within the first interference range, the terminal device whose service wireless access network device is not the first wireless access network device is determined as the third terminal device, and then the third terminal device is switched from the second wireless access network device to the first wireless access network device, thereby avoiding the first terminal device being interfered with when the first wireless access network device interferes with the target device.

[0016] In one possible design, the communication method also includes: sending third information, where the third information indicates that the first wireless access network device interferes with the target device.

[0017] In one possible design, the fourth information also includes first location information, and the first location information indicates the location of the target device after being interfered with; when the fourth information indicates that the interference fails on the first frequency band, the communication method also includes: determining a third wireless access network device and a fourth wireless access network device according to the first location information, the third wireless access network device is used to interfere with the target device, the fourth wireless access network device is a service wireless access network device for the fifth terminal device, the fifth terminal device is located within the signal coverage range of the third wireless access network device, and the location of the target device after being interfered with is located within the signal coverage range of the third wireless access network device.

[0018] In combination with the first aspect and the second aspect, in a possible design, the communication method also includes: receiving fourth information, the fourth information indicating whether the interference is successful on the first frequency band, the first frequency band being one of at least one frequency band of the first wireless access network device.

[0019] In combination with the first aspect and the second aspect, in one possible design, the fourth information includes status information of the target device; the status information includes first status information or second status information, and when the interference is successful on the first frequency band, the status information is the first status information, and when the interference fails on the first frequency band, the status information is the second status information.

[0020] In combination with the first aspect and the second aspect, in one possible design, the first status information indicates that the target device continues to move away from the center of the signal coverage of the first cell, or the target device continues to land within the signal coverage of the first cell, and the frequency point of the first cell is within the first frequency band.

[0021] In combination with the first aspect and the second aspect, in a possible design, the communication method also includes: receiving fifth information, the fifth information indicating a second interference range; when the fourth information indicates that the interference is successful on the first frequency band, determining whether the interference is successful within the second interference range.

[0022] In combination with the first aspect and the second aspect, in a possible design, the fourth information also includes first position information, and the first position information indicates the position of the target device after the interference; when the position of the target device after the interference is outside the second interference range, the interference is successful within the second interference range; when the position of the target device after the interference is within the second interference range, the interference fails within the second interference range.

[0023] In combination with the first aspect and the second aspect, in a possible design, when the fourth information indicates that the interference is successful in the first frequency band and the position of the target device after the interference is outside the second interference range, the communication method also includes: sending sixth information, and the sixth information indicates that the interference is successful within the second interference range.

[0024] In combination with the first aspect and the second aspect, in one possible design, when the fourth information indicates that the interference is successful on the first frequency band and the position of the target device after the interference is within the second interference range, the communication method further includes: when the position of the target device after the interference is outside the signal coverage range of the cell in the first frequency band, determining, based on the first position information, a third wireless access network device that will interfere with the target device after the interference, and the position of the target device after the interference is within the signal coverage range of the third wireless access network device.

[0025] In combination with the first aspect and the second aspect, in a possible design, when the location of the target device after being interfered is within the signal coverage of the cell of the first frequency band, seventh information is sent to the first wireless access network device, and the seventh information instructs the first wireless access network device to continue to interfere with the target device on the first frequency band.

[0026] In a third aspect, a communication method is provided, which can be executed by a first wireless access network device, or by a component of the first wireless access network device, such as a processor, a chip, or a chip system of the first wireless access network device, or by a logic module or software that can implement all or part of the functions of the first wireless access network device. The method includes: when the first terminal device successfully migrates from the signal coverage range of the first wireless access network device, interfering with a target device, the target device being located within the signal coverage range of the first wireless access network device.

[0027] Based on this solution, since the first terminal device successfully migrates from the signal coverage range of the first wireless access network device, when the first access network device interferes with the target device, it can avoid that the first terminal device is also interfered with.

[0028] In one possible design, interfering with a target device includes sending a first noise signal, where the first noise signal is carried in a first time unit, and the first time unit includes at least one downlink time unit.

[0029] Based on this possible design, the first wireless access network device can send a first noise signal in at least one downlink time unit, for example, can send the first noise signal in continuous downlink time units, thereby being able to continuously interfere with the target device, causing the target device to be continuously interfered with, thereby increasing the packet loss rate of the target device and improving the interference effect.

[0030] In a fourth aspect, a communication method is provided, which can be executed by a first wireless access network device, or by a component of the first wireless access network device, such as a processor, a chip, or a chip system of the first wireless access network device, or can be implemented by a logic module or software that can implement all or part of the functions of the first wireless access network device. The method includes: when a third terminal device switches from a second wireless access network device to a first wireless access network device, interfering with a target device, and the target device and the third terminal device are located within the signal coverage range of the first wireless access network device.

[0031] Based on this solution, after the third terminal device switches from the second radio access network device to the first radio access network device, the first radio access network device can interfere with the target device, thereby preventing the third terminal device from being interfered with.

[0032] In one possible design, interfering with a target device includes sending a second noise signal, where the second noise signal is carried in a second time unit, and the second time unit is a time unit that does not carry downlink information in at least one downlink time unit.

[0033] Based on this possible design, after the third terminal device switches from the second radio access network device to the first radio access network device, the third terminal device can communicate with the first radio access network device. The time unit for sending the second noise signal is a time unit that does not carry downlink information, that is, the first radio access network device sends the second noise signal in a time unit that does not communicate with the third terminal device. This prevents the communication service of the third terminal device from being interfered with.

[0034] In combination with the third aspect and the fourth aspect, in a possible design, interfering with the target device includes: interfering with the target device on a first frequency band, the first frequency band being one of at least one frequency band of a first wireless access network device; the communication method also includes: sending fourth information, the fourth information indicating whether the interference is successful on the first frequency band.

[0035] In combination with the third aspect and the fourth aspect, in a possible design, when a preset condition is met, the fourth information indicates that interference on the first frequency band is successful; when the preset condition is not met, the fourth information indicates that interference on the first frequency band fails;

[0036] The preset conditions include: in the process of interfering with the target device, the first distance is greater than the second distance, the first distance is the distance between the target device and the center of the signal coverage range of the first cell at the first moment, the second distance is the distance between the target device and the center of the signal coverage range of the first cell at the second moment, and the first moment is after the second moment; and / or,

[0037] During the interference with the target device, the height of the target device at the third moment is lower than the height of the target device at the fourth moment, and the third moment is located after the fourth moment.

[0038] In combination with the third aspect and the fourth aspect, in a possible design, the fourth information includes status information of the target device. During the process of interfering with the target device, when the first distance is greater than the second distance, the status information indicates that the target device continues to move away from the center of the signal coverage of the first cell; during the process of interfering with the target device, when the height of the target device at the third moment is lower than the height of the target device at the fourth moment, the status information includes that the target device continues to descend within the signal coverage of the first cell.

[0039] In a fifth aspect, a communication method is provided, which can be executed by a second wireless access network device, or by a component of the second wireless access network device, such as a processor, a chip, or a chip system of the second wireless access network device, or can be implemented by a logic module or software that can implement all or part of the functions of the second wireless access network device. The method includes: receiving ninth information, the ninth information indicating that the second wireless access network device requests to switch the third terminal device to the first wireless access network device; sending tenth information to the first wireless access network device, the tenth information is used to request to switch the third terminal device served by the second wireless access network device to the first wireless access network device, and the third terminal device is located in the signal coverage range of the first wireless access network device.

[0040] Based on this scheme, the second wireless access network device can, according to the instructions of the ninth information, request the first wireless access network device to switch the third terminal device (located within the first signal coverage range, and the serving wireless access network device is a terminal device of the second serving wireless access network device) to the first wireless access network device, so that after the third terminal device is switched from the second wireless access network device to the first wireless access network device, the first wireless access network device can interfere with the target device, thereby avoiding interference to the third terminal device.

[0089] In order to facilitate understanding of the technical solutions of the embodiments of the present application, a brief introduction to the related technologies of the present application is first given as follows.

[0090] 1. Slot:

[0091] In new radio (NR), for a normal cyclic prefix (CP), one time slot contains 14 orthogonal frequency division multiplexing (OFDM) symbols (hereinafter referred to as symbols). For an extended CP, one time slot contains 12 symbols. For ease of description, in an embodiment of the present application, unless otherwise specified, one time slot contains 14 symbols. Exemplarily, in a time slot, the 14 symbols are numbered in ascending order, with the smallest number being 0 and the largest number being 13. In fact, in a time slot, the number of symbols may also exist in other implementation forms, which is not limited in this application.

[0092] A time slot can be an uplink time slot (U) or a downlink time slot (D) or a special time slot (S). The uplink time slot is configured to be used only for uplink transmission, and all symbols in the uplink time slot are uplink symbols, that is, the uplink symbols are configured to be used only for uplink transmission; the downlink time slot is configured to be used only for downlink transmission, and all symbols in the downlink time slot are downlink symbols, that is, the downlink symbols are configured to be used only for downlink transmission; the special time slot can be configured to be used for uplink transmission, or configured to be used for downlink transmission, but cannot be used for uplink and downlink transmission at the same time, and the special time slot can be used as a switching point between uplink and downlink, and the symbols in the special time slot can include a part of uplink symbols, a part of downlink symbols and interval symbols, and the interval symbols are located between the uplink symbols and the downlink symbols in the special time slot, and data cannot be sent on the interval symbols.

[0093] It should be understood that in uplink transmission, the terminal device sends uplink data and the wireless access network device receives uplink data. In downlink transmission, the wireless access network device sends downlink data and the terminal device receives downlink data.

[0094] 2. Unmanned aerial vehicle (UAV) countermeasure technology:

[0095] Drone countermeasure technology refers to the use of a series of technical means to counter illegal UAV interference. Drone countermeasure technology includes wireless interference technology, net capture technology, etc. Among them, drone interference technology interferes with the drone positioning system or control radio signals, causing illegal UAVs to lose control and make forced landings, hover, or return. Since the frequency band of illegal UAVs is usually unknown when interfering with countermeasure technology, the following three methods can be used for interference:

[0096] (1) Blocking jamming technology: This is to jam the entire frequency band so that the frequency band of the illegal UAV can be jammed. However, under the blocking jamming technology, the jamming power allocated to each frequency band is low, resulting in reduced jamming efficiency.

[0097] (2) Scanning jamming technology: that is, repeatedly scanning and sending jamming signals to each frequency band in the order from high frequency to low frequency or from low frequency to high frequency, thereby jamming illegal UAVs.

[0098] (3) Frequency-aiming jamming technology: that is, through spectrum listening and analysis, the frequency band of the illegal UAV is determined, and then the frequency band is interfered. Among them, the spectrum listening analyzer can capture the communication signal between the illegal UAV and its remote control. Since the distance between the signal and the listening analyzer is related to time, that is, the distance between the signal and the listening analyzer is the product of the transmission speed of the electromagnetic wave and the time required to capture the signal. Therefore, the position of the signal source (i.e., the illegal UAV) can be calculated based on the signal arrival time difference (TDOA) between two spectrum listening analyzers in multiple spectrum listening analyzers. Among them, the multiple spectrum listening analyzers include greater than or equal to 3 spectrum listening analyzers.

[0099] For example, Figure 1As shown, there are three listening stations (i.e., listening station 1-listening station 3) respectively equipped with a spectrum analyzer, wherein listening station 1 captures the signal at time T+k1 (i.e., receives the signal at time T+k1), listening station 2 captures the signal at time T+k2, and listening station 3 captures the signal at time T+k3. According to the TDOA of the signals of each two of the three listening stations, the distance difference between the two listening stations is determined, and the position of the signal source is further determined according to the distance difference.

[0100] Figure 1 The error radius of the positioning method shown is 30 meters (meter, m)-50m, and the factors causing the error include clock asynchrony and different signal processing delays. Among them, clock synchronization is related to crystal oscillator accuracy and timing accuracy. In the case of clock asynchrony, every 20 nanoseconds (nanosecond, ns) can correspond to an error of 6m.

[0101] In addition, spectrum analyzers are easily affected by the number of signal sources, making it difficult to distinguish whether it is an illegal UAV and locate it. In an environment with complex electromagnetic environment (such as in a city), Figure 2 As shown, when an illegal UAV is in the 2.4 GHz frequency band, it can be mixed with other legal UAVs (such as legal UAVs in 2.4 GHz or 5.8 GHz). At this time, the spectrum analyzer can only identify whether there are UAVs in each frequency band, but cannot determine the frequency band where the illegal UAV is located.

[0102] In addition, the aiming jamming technology supports the determination of the signal source of the illegal UAV from less than or equal to 10 signal sources within a range of 2 kilometers (km). Therefore, when there are many or dense signal sources and / or frequency bands, it is difficult for this technology to determine the signal source of the illegal UAV, and therefore, it is impossible to jam the illegal UAV.

[0103] 3. Wireless sensing technology:

[0104] Wireless sensing technology refers to the use of radio signals to obtain information such as the existence and positioning of a target. Wireless sensing technology can include sensing technology that relies on terminal devices (device-based sensing) and sensing technology that does not rely on terminal devices (device-free sensing).

[0105] Among them, the perception technology that relies on terminal devices can be applied to cellular networks, and in this case, the technology can be called cellular positioning technology. That is, through the interaction between the base station and the terminal device, the base station side obtains the round-trip time information or angle information of the uplink and downlink signals, so that the measurement signal can be calculated on the core network or edge side to obtain the location of the terminal device.

[0106] The perception technology that does not rely on terminal equipment originated from radar technology. With the development of radar and communication technology, signal processing and hardware design are converging. Based on this, a synaesthesia (also known as communication perception fusion) technology is proposed. Through signal joint design and / or hardware sharing, the unified design of communication and perception functions is realized, thereby obtaining spectrum sharing, cost reduction, simplified deployment and other gains. Based on the synaesthesia technology, wireless signals can be transmitted to objects through a transmitter to perceive objects. Specifically, since the area of ​​the object can reflect the signal, the receiver can receive the reflected wireless signal and analyze the signal to obtain the perception measurement of the object such as angle, delay, etc. In cellular networks, the communication technology of wireless base stations has evolved towards multi-antenna, multi-input multi-output (MIMO) and large-scale arrays, which is similar to radar technology. It has the characteristics of wide deployment and rich spectrum, which can realize the location perception of objects. Applicable scenarios include UAV supervision, high-speed rail perimeter intrusion detection and other fields.

[0107] 4. UAV communication:

[0108] UAV can achieve beyond visual range flight by remote control through base station, which makes UAV break the limitation of short-range remote control of existing private remote controllers and achieve activities in a larger range. The 3rd Generation Partnership Project (3GPP) TS23.256 defines the standard process for UAV authentication cellular network. Figure 3 As shown, for a UAV with a cellular communication module (or a UAV accessing a cellular network, also known as a legitimate UAV), when the UAV initiates a registration access request to the cellular network, or an unmanned aerial system (UAS) service provider (USS) network element (or a unified threat management (UTM) network element) initiates a re-authentication request for a registered UAV at any time, the 3GPP network interacts with the USS network element (or UTM network element) through the UAS Network Function (UAS-NF) network element deployed in the network exposure function (NEF). For example, the UAS-NF network element sends the location information, identity identification and other information of the UAV to the USS network element (or UTM network element), and the USS network element (or UTM network element) performs authentication (such as location information authentication) on the information of the UAV (such as location information, identity identification, etc.), and returns the corresponding authentication result and session management information to the UAS-NF network element.

[0109] Based on the above Figure 3 In the drone authentication management architecture shown in the figure, the USS network element (or UTM network element) can obtain the location of all UAVs (i.e. legal UAVs) that access the cellular network in the specified airspace from the UAS-NF network element; in addition, the USS can obtain the location of all objects in the specified airspace from the base station with interawareness technology through the network management system (including the network management system (NMS) and the equipment management system (EMS)). Thus, it can distinguish whether there are illegal objects in the specified airspace, as well as the location of illegal objects and other characteristic information.

[0110] For example, a USS network element (or a UTM network element) may be Figure 4 The process shown in the figure obtains the location and other characteristic information of the illegal object. Figure 4 In the present invention, the USS network element (or UTM network element) can send a target differentiation service request to the NMS network element, wherein the target differentiation service request may include the regulatory airspace range and / or the location of a legal UAV within the regulatory airspace range. After receiving the target differentiation service request, the NMS network element determines the EMS network element participating in this service request among multiple EMS network elements according to the regulatory airspace range, and forwards the target differentiation service request to the EMS network element. The EMS network element determines the base station with interawareness technology corresponding to the signal coverage range of the regulatory airspace range, and sends an airspace perception service request to the base station. The airspace perception service request includes configuration parameters for perception (such as perception accuracy, perception range (i.e., regulatory airspace range), resolution, etc.). The base station performs airspace perception through parameter configuration, and sends an airspace perception service response to the EMS network element based on the perception result. If the perception is successful (i.e., the object is perceived), the airspace perception service response includes the location of the perceived object; if the perception fails (i.e., the object is not perceived), the airspace perception service response includes a failure prompt. The EMS network element associates the legal UAV with the sensed objects, determines whether there are illegal UAVs among the sensed objects, and sends a target differentiation service response to the NMS network element, indicating that the differentiation is successful. The target differentiation service response includes the locations of all sensed objects and whether there are illegal objects; if there are illegal objects, the target differentiation service response may also include the location of the illegal objects. The NMS network element sends the received target differentiation service response to the USS network element (or UTM network element).

[0111] For scenarios where the electromagnetic environment is complex and aiming frequency interference is difficult to use, the USS network element (or UTM network element) can counter illegal UAVs through sweeping frequency interference. After the USS network element (or UTM network element) senses an illegal object, the USS network element (or UTM network element) activates the sweeping frequency interference system to implement sweeping frequency interference on the illegal UAV, and observes whether the illegal UAV is successfully interfered through a base station with intersensory technology. If the illegal UAV leaves the designated area (i.e., the regulated airspace range) or falls, the interference is considered successful.

[0112] For example, Figure 5 As shown in FIG. 1 , the USS network element (or UTM network element) can use the sweep frequency interference technology to enable the sweep frequency interference system to send interference signals to the location of the illegal UAV to interfere with the illegal UAV. However, if there are legal UAVs in the frequency band where the illegal UAV is located, when the illegal UAV is interfered with, the legal UAVs in the frequency band will also be interfered with. Figure 5 The area within the dotted line in is the coverage area of ​​the interference signal on the frequency band where the illegal UAV is located. Therefore, how to prevent the legal UAV from being interfered with while interfering with the illegal UAV is an urgent problem to be solved.

[0113] Based on this, an embodiment of the present application provides a communication method, in which, when a first terminal device and a target device exist simultaneously within a signal coverage range of a fifth-line access network device, a first wireless access network device for interfering with the target device may send first information to instruct to migrate the first terminal device from the signal coverage range of the first wireless access network device. Therefore, the first access network device may subsequently interfere with the target device after the first terminal device migrates from the signal coverage range of the first wireless access network device, thereby preventing the first terminal device from being interfered with.

[0114] The technical solution provided in this application can be used in various communication systems, which can be a third generation partnership project (3GPP) communication system, such as a fourth generation (4G) long term evolution (LTE) system, a fifth generation (5G) new radio (NR) system, a vehicle to everything (V2X) system, a system of LTE and NR hybrid networking, or a device-to-device (D2D) system, a machine-to-machine (M2M) communication system, an Internet of Things (IoT), and other next generation communication systems.

It can be understood that in the embodiment of the present application, the wireless access network device can perform some or all of the steps in the embodiment of the present application, and these steps or operations are only examples. The embodiment of the present application can also perform other operations or variations of various operations.

[0140] It should be noted that the message names between the devices or the names of the parameters in the messages in the following embodiments of the present application are only examples, and other names may be used in the specific implementation, and the embodiments of the present application do not specifically limit this.

[0141] It should be noted that this application Figure 6-Figure 9 Any of the items and the following first network element is a first network element in which the target device exists in the supervised airspace of at least one first network element belonging to the airspace supervised by the second network element. The third network element is a third network element in which the target device exists in the supervised airspace of at least one third network element belonging to the airspace supervised by the second network element.

[0142] Optional, based on Figure 6 or Figure 7 , Figure 8 or Fig. 9 The two communication systems shown and the communication method provided in the embodiments of the present application can be implemented based on the following two scenarios:

[0143] Scenario 1: The communication method provided in the embodiment of the present application can be applied to Figure 6 or Figure 7 The communication system shown.

[0144] See also Fig.10 , that is, a communication method for application in the following scenario is provided for the embodiment of the present application, and the communication method may include the following steps:

[0145] S1001. A first network element obtains location information of a target device.

[0146] As an example, the first network element may obtain the location information of the target device from the second network element. Exemplarily, the second network element may send the fifth information to the first network element. Correspondingly, the first network element receives the fifth information from the second network element. The fifth information includes the location information of the target device. Exemplarily, the fifth information may be called an interference service request.

[0147] Optionally, the fifth information may also include a second interference range. The second interference range is used to determine whether the interference with the target device is successful. Exemplarily, the second interference range may also be referred to as a regulatory airspace range. The second interference range may be represented by a polygon consisting of a set of ordered longitude and latitude coordinate points.

[0148] In this example, the second network element may determine to send the fifth information to the first network element through the following two possible implementations:

[0149] In one possible implementation, Figure 6 In the communication system shown, the second network element can determine, according to the location information of the target device, the first network element corresponding to the airspace where the target device is located in at least one first network element to which its supervised airspace belongs as Figure 6 The first network element thereby sends the fifth information to the first network element.

[0150] In another possible implementation, Figure 7 In the communication system shown, the second network element can determine, according to the location information of the target device, the third network element corresponding to the airspace where the target device is located in at least one third network element to which its supervised airspace belongs as Figure 7 The third network element is determined in at least one first network element. Figure 7 The first network element thereby sends the fifth information to the first network element.

[0151] For example, in this possible implementation, Fig.11 As shown, the process of the second network element sending the fifth information to the first network element may be based on the following steps S1001A-S1001C, that is, step S1001 may be replaced by steps S1001A-S1001C:

[0152] S1001A: The second network element sends fifth information to the third network element. Correspondingly, the third network element receives the fifth information from the second network element.

[0153] S1001B: The third network element determines, based on the location information of the target device, a first network element in the at least one first network element in the airspace it supervises, where the target device is located. Figure 7 The first network element (i.e. Fig.11 the first network element).

[0154] S1001C: The third network element sends fifth information to the first network element. Correspondingly, the first network element receives the fifth information from the first network element.

[0155] As another example, the first network element may utilize the perception of the wireless access network device with synesthesia technology within the regulatory airspace to determine the target device within the regulatory airspace.

[0156] Exemplarily, the first network element may be as described above. Figure 4 The EMS network elements shown are based on Figure 4 The process shown obtains the location information of the target device; the method for obtaining the regulatory airspace range can refer to the relevant description of the above-mentioned regulatory airspace range, which will not be repeated here.

[0157] For the convenience of description, the following description is given by taking an example in which a first network element obtains location information of a target device from a second network element.

[0158] S1002. Determine, according to location information of a target device, a first wireless access network device that will interfere with the target device, wherein the target device is located within a signal coverage range of the first wireless access network device.

[0159] Optionally, the first radio access network device may be: any one of the radio access network devices corresponding to a plurality of signal coverage ranges where the target device is located.

[0160] Exemplarily, the first radio access network device may be a radio access network device that is closest to the target device among the radio access network devices corresponding to a plurality of signal coverage ranges where the target device is located.

[0161] S1003. The first network element sends first information to the second network element. Correspondingly, the second network element receives the first information from the first network element. The first information indicates to move the first terminal device out of the signal coverage of the first wireless access network device, and the first terminal device is a terminal device within the signal coverage of the first wireless access network device.

[0162] Exemplarily, the terminal device may include a UAV. The first terminal device may be understood as a UAV accessing a cellular network, or a legal UAV.

[0163] Optionally, the signal coverage range of the first radio access network device may include the following three implementations:

[0164] As a first possible implementation, the signal coverage range of the first radio access network device may be understood as: the current signal coverage range of the first radio access network device.

[0165] As a second possible implementation, the signal coverage range of the first wireless access network device can be understood as: the signal coverage range when the first wireless access network device sends a signal according to the first power. The first power is greater than or equal to the current signal transmission power of the first wireless access network device. At this time, the signal coverage range of the first wireless access network device can also be called the first interference range. That is, the terminal device can determine the first interference range based on the first power.

[0166] For example, taking the first power as greater than the current signal transmission power of the first radio access network device as an example, Fig.12 As shown in (a), Fig.12 The area within the solid line in (a) is the current signal coverage of the first wireless access network device. Fig.12 The area within the dotted line range in (a) is the signal coverage range when the first wireless access network device sends a signal at the first power. Since the first power is greater than the current signal transmission power of the first wireless access network device, Fig.12 In (a), the area within the dotted line is larger than the area within the solid line.

[0167] Optionally, the first power may be calculated based on an interference signal-to-noise ratio, a distance between the target device and the first radio access network device, and a channel model (such as a channel model defined in the 3GPP standard).

[0168] As a third possible implementation, the signal coverage of the first radio access network device may be understood as: the signal coverage of the first beam sent at the first power in the first radio access network device, wherein the target device is located in the sending direction of the first beam.

[0169] For example, Fig.12 As shown in (b), Fig.12 The area within the solid line in (b) is the current signal coverage of the first wireless access network device. Fig.12 The area within the dotted line range in (b) is the signal coverage range of the first beam sent by the first wireless access network device at the first power. Based on the second possible implementation and the third possible implementation mentioned above, since the first interference range is determined according to the first power, when the first wireless access network device subsequently uses the first power to interfere with the target device, the terminal devices within the first interference range or the signal coverage range of the first beam will be interfered with. Therefore, the terminal devices within the signal coverage range of the first wireless access network device determined according to the first power can be determined as the first terminal devices, and then the first terminal devices can be migrated out of the signal coverage range of the first wireless access network device to avoid the first terminal device being interfered with when the first wireless access network device interferes with the target device.

[0170] Optionally, the first information may include a signal coverage range of the first radio access network device.

[0171] As an example, in Figure 6 In the communication system shown, the first network element can directly communicate with the second network element, so the first network element can directly send the first information to the second network element.

[0172] As another example, in Figure 7 In the communication system shown, since the first network element can communicate with the third network element, and the third network element can communicate with the second network element, the communication between the first network element and the second network element is realized. Therefore, in this example, the first network element sends the first information to the second network element, which may include: the first network element sends the first information to the third network element. After receiving the first information, the third network element sends the first information to the second network element. For example, the third network element may transparently transmit the first information to the second network element. Optionally, Fig.13 As shown, after step S1003, the communication method may further include the following steps:

[0173] S1004. The second network element migrates the first terminal device according to the first information.

[0174] Exemplarily, the second network element may take over the remote control function of the first terminal device, thereby instructing the first terminal device to move out of the signal coverage range of the first radio access network device.

[0175] Optionally, during the migration of the first terminal device, the second network element can sense the location of the first terminal device in real time, determine whether the first terminal device has migrated out of the signal coverage of the first wireless access network device, or determine whether the first terminal device has moved out of the signal coverage of the first wireless access network device.

[0176] Optionally, when it is determined that the first terminal device has migrated out of the signal coverage of the first radio access network device, the following steps may also be performed:

[0177] S1005: The second network element sends second information to the first network element. Correspondingly, the first network element receives the second information from the second network element, wherein the second information indicates that the migration of the first terminal device is successful.

[0178] Exemplarily, the successful migration of the first terminal device can be understood as the first terminal device has moved out of the signal coverage of the first wireless access network device.

[0179] Exemplarily, the process of the second network element sending the second information to the first network element is similar to the process of the first network element sending the first information to the second network element in step S1003. Figure 6In the communication system shown in FIG. 1 , the second network element can directly send the second information to the first network element. Figure 7 In the communication system shown, the second network element sending the second information to the first network element may include: the second network element sending the second information to the third network element. After receiving the second information, the third network element sends the second information to the first network element.

[0180] Optionally, after receiving the second information, the first network element may perform step S1006: the first network element sends third information to the first wireless access network device. Accordingly, the first wireless access network device receives the third information from the first network element. The third information indicates that the first wireless access network device interferes with the target device.

[0181] Optionally, the third information may include at least one of the interference on-time, the signal transmission power during interference (such as the first power), and the signal transmission direction during interference (such as indicating the first beam).

[0182] S1007: The first wireless access network device interferes with the target device.

[0183] S1008. The first wireless access network device sends fourth information to the first network element. Correspondingly, the first network element receives fourth information from the first wireless access network device. The fourth information indicates whether interference is successful on a first frequency band, where the first frequency band is one of at least one frequency band of the first wireless access network device.

[0184] Optionally, the fourth information may include status information of the target device; wherein the status information includes first status information or second status information. When the interference on the first frequency band is successful, the status information is the first status information; when the interference on the first frequency band fails, the status information is the second status information.

[0185] Exemplarily, a wireless access network device is configured with at least one frequency band, and the wireless access network device can be used to interfere on different frequency bands. Among them, the frequency points of multiple cells in the wireless access network device correspond one-to-one to at least one frequency band. That is to say, the frequency points of each cell are located in different frequency bands. The embodiment of the present application is introduced by taking each wireless access network device as an example that the same frequency band is configured.

[0186] Based on scenario one, an embodiment of the present application provides a communication method, in which, when a first terminal device and a target device exist simultaneously within a signal coverage range of a first wireless access network device, the first wireless access network device that interferes with the target device may send first information to instruct the first terminal device to be moved out of the signal coverage range of the first wireless access network device. Therefore, the first access network device may subsequently interfere with the target device after the first terminal device migrates from the signal coverage range of the first wireless access network device, thereby preventing the first terminal device from being interfered with.

[0187] The above is an overall description of the communication method in scenario 1. The following is a detailed introduction to the first terminal device mentioned in the above embodiment.

[0188] Exemplarily, the number of the first terminal devices is greater than or equal to 1. Optionally, the first terminal device may include the following two implementations:

[0189] As an example, the first terminal device can be understood as all terminal devices accessing the cellular network within the signal coverage range of the first wireless access network device.

[0190] For example, Fig.14 As shown, the signal coverage of the first wireless access network device includes terminal devices #1-terminal devices #3 and the target device, and terminal devices #1-terminal devices #3 are all connected to the cellular network. At this time, terminal devices #1-terminal devices #3 can all be determined as first terminal devices.

[0191] As another example, the first terminal device can be understood as a terminal device that accesses a cellular network within the signal coverage of a first wireless access network device, and whose serving wireless access network device is a terminal device of a second wireless access network device.

[0192] For example, Fig.14 As shown, the signal coverage of the first wireless access network device includes terminal devices #1-terminal devices #3 and the target device, and terminal devices #1-terminal devices #3 are all connected to the cellular network, and the service wireless access network devices of terminal devices #1 and #2 are the first wireless access network devices, and the service wireless access network device of terminal device #3 is the first wireless access network device. At this time, terminal device #3 can be determined as the first terminal device.

[0193] The above is an explanation of the method of the first terminal device. The following is a detailed introduction to the process of interfering with the target device mentioned in the above embodiment (ie, the implementation of step S1007).

[0194] Optionally, the first wireless access network device may select a frequency band (i.e., a first frequency band) from at least one frequency band, and perform interference on the first frequency band. The interference result (i.e., the state information of the target device) is notified to the first network element. That is, the first wireless access network device interferes with the target device, including: the first wireless access network device interferes with the target device on the first frequency band.

[0195] Optionally, the first wireless access network device may sense the location information of the target device at a predetermined period during the interference process. And determine the interference result based on the location information of the target device and feed it back to the first network element. Exemplarily, if the first wireless access network device senses the location information of the target device, it can determine whether the interference is effective for the target device by sensing the location information of the target device at different times. Then determine whether the state information is the first state information or the second state information, that is, the fourth information indicates the interference failure or the interference failure on the first frequency band. If the first wireless access network device does not sense the location information of the target device, the state information is the second state information, that is, the fourth information indicates the interference failure on the first frequency band.

[0196] Optionally, the first radio access network device may sense the location information of the target device in real time during the interference process. Exemplarily, the interference result may include the location information of the target device.

[0197] Based on this optional solution, the first wireless access network device can sense the location information of the target device during the interference process, and determine the interference result based on the location information of the target device, and feed it back to the first network element, so that the first network element can know the interference effect and then determine whether to continue to interfere with the target device, thereby ensuring the continuity of the interference implementation.

[0198] Optionally, based on different implementations of the foregoing first terminal device, the first radio access network device may interfere with the target device in the following two ways:

[0199] In one possible implementation, in a case where the first terminal device is within the signal coverage range of the first wireless access network device and accesses all terminal devices of the cellular network, after the migration of the first terminal device is completed, there are no terminal devices accessing the cellular network within the signal coverage range of the first wireless access network device, and thus the first wireless access network device can interfere with the target device for multiple consecutive time units.

[0200] Optionally, the first radio access network device interferes with the target device, including: the first radio access network device sends a first noise signal to the target device, wherein the first noise signal is carried in a first time unit, and the first time unit includes at least one downlink time unit.

[0201] Exemplarily, the first time unit may include a group of continuous downlink time units. For example, the first time unit may include a plurality of time slots of one or more consecutive frames. Exemplarily, the first noise signal may be a white noise signal.

[0202] Exemplarily, the time unit may be a minislot, a time slot, a subframe, a transmission time interval (TTI), etc.

[0203] Based on this possible implementation method, the first wireless access network device can send the first noise signal in at least one downlink time unit, for example, the first noise signal can be sent in continuous downlink time units, so that the target device can be continuously interfered with, so that the target device is continuously interfered with, thereby increasing the packet loss rate of the target device and improving the interference effect.

[0204] In another possible implementation, in a case where the first terminal device is a terminal device that accesses a cellular network within the signal coverage range of a first wireless access network device, and the serving wireless access network device is a terminal device of a second wireless access network device, after the migration of the first terminal device is completed, the remaining devices within the signal coverage range of the first wireless access network device include terminal devices whose serving wireless access network device is the first wireless access network device (for the convenience of description, the terminal devices whose serving wireless access network device is the first wireless access network device are referred to as remaining terminal devices hereinafter) and target devices.

[0205] In this possible implementation, in order to avoid interference to the remaining terminal devices, the first wireless access network device may interfere with the target device in other time units (or also referred to as idle time units) other than the time units occupied by the communication services of the remaining terminal devices according to the communication services of the remaining terminal devices. Exemplarily, taking a group of continuous downlink time units including time unit #1-time unit #9 as an example, if the communication services of the remaining terminal devices are carried in time units including time unit #1-time unit #3, the first wireless access network device may interfere with the target device (such as sending a noise signal) in time unit #4-time unit #9.

[0206] Optionally, the first wireless access network device can construct a random number generation module in the baseband board, enable the random number generation module when there is an idle time unit (i.e., a time unit not used for information signal transmission), and use the generated random number to generate a digital noise signal through a field-programmable gate array (FPGA) module, and send the digital noise signal through an antenna through a digital intermediate frequency module and a digital-to-analog conversion module.

[0207] Based on this possible implementation, after the third terminal device switches from the second radio access network device to the first radio access network device, the third terminal device can communicate with the first radio access network device. The time unit for sending the second noise signal is a time unit that does not carry downlink information, that is, the first radio access network device sends the second noise signal in a time unit that does not communicate with the third terminal device. This prevents the communication service of the third terminal device from being interfered with.

[0208] The following is a detailed description of the situation in which the first wireless access network device is able to perceive the location information of the target device.

[0209] Optionally, after the target device is interfered with, if the interference is effective, the target device will move out of the signal coverage of the first cell, and / or the target device will land; if the interference is ineffective, the target device will not be affected and will continue to operate within the signal coverage of the first cell. The frequency point of the first cell is within the first frequency band. Therefore, the first wireless access network device can perceive the location information of the target device in real time, determine whether the target device is affected by the interference, and then determine whether the interference is effective on the first frequency band.

[0210] Exemplarily, the target device moving out of the signal coverage of the first cell can be understood as: the target device is located in the signal coverage of the first cell, and the target device continues to move away from the center of the signal coverage of the first cell. The target device landing can be understood as: the target device is located in the coverage of the first signal, and the height of the target device continues to decrease. In other words, the first state information includes that the target device continues to move away from the center of the signal coverage of the first cell, or the target device continues to land within the signal coverage of the first cell, and the frequency point of the first cell is within the first frequency band.

[0211] Optionally, the first wireless access network device may determine the location information of the target device obtained by the first wireless access network device during the interference process according to preset conditions, and determine the interference result. For example, when the preset conditions are met, the interference result is successful interference on the first frequency band; at this time, the fourth information may indicate successful interference on the first frequency band, that is, the state information of the target device at this time is the first state information. When the preset conditions are not met, the interference result is failed interference on the first frequency band; at this time, the fourth information indicates failed interference on the first frequency band, that is, the state information of the target device at this time is the second state information.

[0212] Exemplarily, the preset conditions include the following two features:

[0213] Feature 1. During the process of interfering with the target device, the first distance is greater than the second distance, the first distance is the distance between the target device and the center of the signal coverage range of the first cell at the first moment, the second distance is the distance between the target device and the center of the signal coverage range of the first cell at the second moment, and the first moment is after the second moment; wherein the target device is located in the signal coverage range of the first cell.

[0214] Optionally, the time difference between the first moment and the second moment is X seconds. X is a positive integer. Exemplarily, the second moment may be the moment when the interference is turned on, or may be any moment during the interference process. Exemplarily, Fig.15 As shown, Fig.15 The area within the dotted line is the signal coverage of the first cell. Fig.15 As shown in (a), at the first moment and the second moment, the target device is located in the signal coverage range of the first cell. However, compared with the distance between the target device and the center of the signal coverage range of the first cell at the second moment (i.e., the second distance), the distance between the target device and the center of the signal coverage range of the first cell at the first moment (i.e., the first distance) is larger. Therefore, it can be considered that during the interference process from the second moment to the first moment, the target device continues to move away from the center of the signal coverage range of the first cell.

[0215] Or, if Fig.15 As shown in (b), at the second moment, the target device is located within the signal coverage of the first cell, and at the first moment, the target device is located outside the signal coverage of the first cell. Therefore, it can be considered that during the interference process from the second moment to the first moment, the target device moves from the signal coverage of the first cell to outside the signal coverage of the first cell. At this time, the first distance is greater than the second distance, so it can be considered that during the interference process from the second moment to the first moment, the target device continues to move away from the center of the signal coverage of the first cell.

[0216] Optionally, the difference between the first distance and the second distance may be greater than a preset distance threshold. Exemplarily, the preset distance threshold is positively correlated with the value of X. That is, the larger the value of X is, the larger the preset distance threshold is. For example, when the value of X is 2, the preset distance threshold may be 5 meters; when the value of X is 5, the preset distance threshold may be 15 meters, etc. This is not limited here.

[0217] Feature 2: During the interference with the target device, the height of the target device at the third moment is lower than the height of the target device at the fourth moment, and the third moment is located after the fourth moment.

[0218] Optionally, the time difference between the third moment and the fourth moment is Y seconds. Y is a positive integer. Exemplarily, the fourth moment may be the moment when the interference is turned on, or may be any moment during the interference process. Exemplarily, Fig.16 As shown in (a), at the third moment and the fourth moment, the target device is located in the signal coverage of the first cell, but compared with the height of the target device at the fourth moment, the height of the target device at the third moment is lower. Therefore, it can be considered that during the interference process from the fourth moment to the third moment, the height of the target device continues to decrease.

[0219] Or, if Fig.16 As shown in (b), at the third moment and the fourth moment, the target device is located in the signal coverage of the first cell, and the height of the target device at the third moment is 0 meters. At this time, the height of the target device at the third moment is lower than the height of the target device at the fourth moment, so it can be considered that the height of the target device continues to decrease during the interference process from the fourth moment to the third moment.

[0220] Optionally, when the height at the third moment is greater than 0 meters, the height difference between the third moment and the fourth moment is greater than the preset height threshold. Exemplarily, the preset height threshold is positively correlated with the value of Y. That is, the larger the value of Y is, the larger the preset height threshold is. For example, when the value of Y is 2, the preset distance threshold can be 5 meters; when the value of Y is 5, the preset distance threshold can be 20 meters, etc. This is not limited here.

[0221] Exemplarily, after the first wireless access network device senses the location information of the target device at any time during the interference process, it immediately determines whether the interference is successful on the first frequency band at that time (i.e., determines the fourth information), and informs the first network element. In other words, the steps of the first wireless access network device sensing the location information of the target device and determining the fourth information can all be performed during the interference process. Of course, it can also be performed after the interference ends. For example, at this time, the location information of the target device sensed by the first wireless access network device can be the location information of the target device at the moment when the interference ends.

[0222] Optionally, the fourth information may also include at least one of an interference frequency point (ie, a first frequency band), location information of the target device before the interference, and a location of the target device after the interference (or may also be referred to as first location information).

[0223] Exemplarily, the location information of the target device before the interference is performed can be understood as: the location information of the target device before or at the moment when the interference is turned on. The first location information can be understood as: the location information of the target device at any moment during the interference process. For example, the first location information can be the location information of the target device at the first moment, or the first location information can be the location information of the target device at the third moment.

[0224] Optionally, based on different situations of the fourth information, the communication method may further include different steps:

[0225] Case 1: The fourth information indicates that the interference is successful on the first frequency band. Fig.17 As shown, the communication method may further include the following steps S1009-S1010:

[0226] S1009. The first network element determines whether the location of the target device after being interfered is within the signal coverage of the first cell.

[0227] When the location of the target device after being interfered is within the signal coverage of the first cell, step S1010 may be performed: the first network element sends seventh information to the first wireless access network device. Accordingly, the first wireless access network device receives the seventh information from the first network element. The seventh information indicates that the first wireless access network device continues to interfere with the target device on the first frequency band.

[0228] Optionally, the process in which the first radio access network device continues to interfere with the target device on the first frequency band is similar to the above step S1007. For details, reference may be made to the relevant description of the above step S1007, which will not be repeated here.

[0229] When the target device is located outside the signal coverage of the first cell after being interfered with, Fig.18 As shown, step S1011 may be executed: the first network element determines whether interference is successful within the second interference range.

[0230] Optionally, when the position of the target device after the interference is outside the second interference range, the interference is successful within the second interference range; when the position of the target device after the interference is within the second interference range, the interference fails within the second interference range.

[0231] Optionally, in the case where interference is successful within the second interference range, such as Fig.18 As shown, step S1012 may be performed: the first network element sends sixth information to the second network element. Correspondingly, the second network element receives the sixth information from the first network element. The sixth information indicates that interference is successful within the second interference range.

[0232] Optionally, the sixth information may include the first location information, and further, may include a frequency band where interference has been performed (such as the first frequency band).

[0233] Exemplarily, the process of the first network element sending the sixth information to the second network element is similar to the process of the first network element sending the first information to the second network element in the above step S1003. For details, please refer to the relevant description of the above step S1003 and will not be repeated here.

[0234] Optionally, when interference fails within the second interference range, the first network element may determine a third radio access network device that will interfere with the target device after the interference based on the first position information (i.e., the position of the target device after the interference).

[0235] Exemplarily, the third wireless access network device may be: any wireless access network device among the wireless access network devices corresponding to the multiple signal coverage ranges where the location of the target device is located after the interference. The third wireless access network device and the first wireless access network device may be the same wireless access network device. For example, the third wireless access network device may be the wireless access network device closest to the target device among the wireless access network devices corresponding to the multiple signal coverage ranges where the location of the target device is located after the interference.

[0236] Optionally, in the event of interference failure within the second interference range, the first network element determines the third wireless access network device based on the first location information, including: in the event of interference failure within the second interference range, the first network element determines whether there is a frequency band in at least one frequency band other than the first frequency band that is not interfered with; if there is a frequency band that is not interfered with, determine the third wireless access network device based on the first location information.

[0237] Optionally, after determining the third radio access network device, the first network element may also determine the second terminal device. Exemplarily, the implementation of the second terminal device is similar to that of the first terminal device, and specific reference may be made to the relevant description of the first terminal device, which will not be repeated here.

[0238] Optionally, after determining the third wireless access network device, the third wireless access network device may interfere with the target device on the second frequency band. The frequency band that is not interfered with includes the second frequency band, and the first location information (the location of the target device after being interfered with) is located within the signal coverage range of the second cell, and the frequency point of the second cell is located in the second frequency band.

[0239] Exemplarily, the process of the third radio access network device performing interference is similar to the above step S1007. For details, reference may be made to the relevant description of the above step S1007, which will not be repeated here.

[0240] Optionally, in the case where interference fails within the second interference range and there is no frequency band where no interference is performed, the first network element may send eighth information to the second network element. Accordingly, the second network element receives the eighth information from the first network element. The eighth information indicates that interference fails within the second interference range.

[0241] Exemplarily, the process of the first network element sending the eighth information to the second network element is similar to the process of the first network element sending the sixth information to the second network element. For details, please refer to the relevant description of the above step S1012, which will not be repeated here.

[0242] Optionally, the eighth information may include at least one of the first location information, the interference record, and the reason for the interference failure. The interference record may include a frequency band where interference has been performed (such as the first frequency band) and a frequency band where interference has not been performed. The reason for the interference failure may include that the first radio access network device does not perceive the location information of the target device, or that there is no frequency band where interference has not been performed.

[0243] Case 2: The fourth information indicates that interference failed on the first frequency band.

[0244] As an example, in the case where the fourth information indicates that the interference on the first frequency band fails because the first wireless access network device does not perceive the location information of the target device, after step S1008, as shown in FIG. Fig.19 As shown, the communication method may further include step S1013: the first network element determines whether interference is successful within the second interference range.

[0245] Exemplarily, since the first wireless access network device does not perceive the location information of the target device, the first network element cannot know whether the location of the interfered target device is within the second interference range, and therefore it can be considered that the interference fails within the second interference range.

[0246] Optionally, the first network element may send the eighth information to the second network element. Accordingly, the second network element receives the eighth information from the first network element. The eighth information indicates that the interference fails within the second interference range. At this time, the eighth information may include the interference record and / or the reason for the interference failure. The reason for the interference failure is that the first wireless access network device does not perceive the location information of the target device.

[0247] As another example, when the fourth information indicates that interference on the first frequency band fails because a preset condition is not met, the first network element may determine the third radio access network device according to the first location information.

[0248] Exemplarily, the implementation of the third wireless access network device is the same as the implementation of the third wireless access network device mentioned above. For details, please refer to the relevant description of the third wireless access network device mentioned above, which will not be repeated here.

[0249] Scenario 2: The communication method provided in the embodiment of the present application can be applied to Figure 8 or Fig. 9 The communication system shown.

[0250] See also Fig. 20 , that is, a communication method for application in scenario 2 is provided for the embodiment of the present application, and the communication method may include the following steps:

[0251] S2001. The first network element obtains location information of a target device.

[0252] As an example, the first network element may obtain the location information of the target device from the second network element. Exemplarily, the second network element may send the fifth information to the first network element. Accordingly, the first network element receives the fifth information from the second network element. The fifth information includes the location information of the target device. Exemplarily, the fifth information may be referred to as an interference service request.

[0253] Optionally, the fifth information may also include a second interference range. The second interference range is used to determine whether the interference with the target device is successful. Exemplarily, the second interference range may also be referred to as a regulatory airspace range. The second interference range may be represented by a polygon consisting of a set of ordered longitude and latitude coordinate points.

[0254] In this example, the second network element may determine to send the fifth information to the first network element through the following two possible implementations:

[0255] In one possible implementation, Figure 8 In the communication system shown, the second network element can determine, according to the location information of the target device, the first network element corresponding to the airspace where the target device is located in at least one first network element to which its supervised airspace belongs as Figure 8 The first network element thereby sends the fifth information to the first network element.

[0256] In another possible implementation, Fig. 9 In the communication system shown, the second network element can determine, according to the location information of the target device, the third network element corresponding to the airspace where the target device is located in at least one third network element to which its supervised airspace belongs as Fig. 9 The third network element is determined in at least one first network element. Fig. 9 The first network element thereby sends the fifth information to the first network element.

[0257] For example, in this possible implementation, Fig.21As shown, the process of the second network element sending the fifth information to the first network element may be based on the following steps S2001A-S2001C, that is, step S2001 may be replaced by steps S2001A-S2001C:

[0258] S2001A: The second network element sends fifth information to the third network element. Correspondingly, the third network element receives the fifth information from the second network element.

[0259] S2001B: The third network element determines, based on the location information of the target device, a first network element in the at least one first network element in the airspace it supervises, where the target device is located. Fig. 9 The first network element (i.e. Fig.21 the first network element).

[0260] S2001C: The third network element sends fifth information to the first network element. Correspondingly, the first network element receives the fifth information from the first network element.

[0261] As another example, the first network element may utilize the perception of the wireless access network device with synesthesia technology within the regulatory airspace to determine the target device within the regulatory airspace.

[0262] Exemplarily, the first network element may be as described above. Figure 4 The EMS network elements shown are based on Figure 4 The process shown obtains the location information of the target device; the method for obtaining the regulatory airspace range can refer to the relevant description of the above-mentioned regulatory airspace range, which will not be repeated here.

[0263] For the convenience of description, the following description is given by taking an example in which a first network element obtains location information of a target device from a second network element.

[0264] S2002. The first network element determines the first wireless access network device and the second wireless access network device according to the location information of the target device. The target device exists within the signal coverage of the first wireless access network device. The first wireless access network device will interfere with the target device. The second wireless access network device is a service wireless access network device for the third terminal device. The third terminal device is located within the signal coverage of the first wireless access network device.

[0265] S2003. The first network element sends ninth information to the second wireless access network device, where the ninth information is used by the second wireless access network device to request that the third terminal device be switched to the first wireless access network device.

[0266] Optionally, the ninth information may also be used to indicate the address information of the first radio access network device. The second radio access network device may inform the third terminal device of the address information of the first radio access network device, so that the third terminal device can switch to the first radio access network device.

[0267] Optionally, after step S2002, as Fig. 22 As shown, the communication method may further include step S2004: the first network element sends third information to the first radio access network device, where the third information indicates that the first radio access network device interferes with the target device.

[0268] Exemplarily, the implementation of the third information can refer to the relevant description of the third information in the above scenario one, which will not be repeated here.

[0269] It should be noted that the above steps S2001-S2003 are only exemplary descriptions of the communication process. There is no restriction on the execution order between step S2003 and step S2004. For example, step S2003 can be executed before step S2004; or, step S2003 can be executed after step S2004; or, step S2003 can be executed simultaneously with step S2004.

[0270] After step S2003, Fig. 22 As shown, the method may also include the following steps:

[0271] S2005. The second wireless access network device sends tenth information to the first wireless access network device, where the tenth information is used to request that the third terminal device be connected to the first wireless access network device.

[0272] S2006: The first wireless access network device sends access permission response information to the second wireless access network device. Correspondingly, the second wireless access network device receives the access permission response information from the first wireless access device.

[0273] S2007: The second wireless access network device sends the address information of the first wireless access network device to the third terminal device. Correspondingly, the third terminal device receives the address information of the first wireless access network device from the second wireless access network device.

[0274] S2008. The third terminal device accesses the first wireless access network device.

[0275] Optionally, after step S2008, user data may be forwarded between the second radio access network device and the third terminal device through the first radio access network device.

[0276] S2009: The first wireless access network device interferes with the target device.

[0277] Optionally, the first wireless access network device interferes with the target device, including: the first wireless access network device sends a second noise signal, the second noise signal is carried in a second time unit, and the second time unit is a time unit that does not carry downlink information in at least one downlink time unit.

[0278] Optionally, in order to avoid interference to terminal devices accessing the cellular network within the signal coverage of the first wireless access network device, the first wireless access network device may interfere with the target device in time units other than the time units occupied by the communication service of the terminal device accessing the cellular network based on the communication service of the terminal device accessing the cellular network.

[0279] Exemplarily, taking a group of continuous downlink time units including time unit #1-time unit #9 as an example, if the communication service of the terminal device accessing the cellular network is carried on the time units including time unit #1-time unit #3, the first wireless access network device can interfere with the target device (such as sending a noise signal) on time unit #4-time unit #9.

[0280] Based on the selected solution, after the third terminal device switches from the second radio access network device to the first radio access network device, the third terminal device can communicate with the first radio access network device. The time unit for sending the second noise signal is a time unit that does not carry downlink information, that is, the first radio access network device sends the second noise signal in a time unit that does not communicate with the third terminal device. This prevents the communication service of the third terminal device from being interfered with.

[0281] Based on scenario 2, the embodiment of the present application provides a communication method, in which, when a third terminal device and a target device exist simultaneously within the signal coverage range of a first wireless access network device, the first network element can instruct the second wireless access network device to switch the third terminal device to the first wireless access network device. Therefore, after the third terminal device accesses the first wireless access network device, the first wireless access network device can learn the time of the communication service of the third terminal device, so that when interfering with the target device, the time of the communication service of the third terminal device can be considered, for example, the target device is interfered with at other times other than the time of the communication service of the third terminal device, so as to avoid the third terminal device from being interfered with.

[0282] The third terminal device mentioned in the above embodiment is introduced in detail below.

[0283] As an example, the third terminal device can be understood as a terminal device that accesses the cellular network within the signal coverage of the first wireless access network device, and the serving wireless access network device is a terminal device of the second wireless access network device.

[0284] Optionally, the first network element determines the second wireless access network device, including: the first network element may determine a first interference range based on a first power, the first power being greater than or equal to a current signal transmission power of the first wireless access network device, and the first interference range being a signal coverage range when the first wireless access network device transmits a signal according to the first power; determining, among at least one terminal device within the first interference range, a terminal device whose service wireless access network device is not the first wireless access network device as a third terminal device; and determining the service wireless access network device of the third terminal device as the second wireless access network device.

[0286] Based on this optional scheme, since the first interference range is determined according to the first power, when the first wireless access network device subsequently uses the first power to interfere with the target device, all terminal devices within the first interference range will be interfered with. Therefore, among the terminal devices within the first interference range, the terminal device whose service wireless access network device is not the first wireless access network device is determined as the third terminal device, and then the third terminal device is switched from the second wireless access network device to the first wireless access network device, thereby avoiding interference to the first terminal device when the first wireless access network device interferes with the target device.

[0292] S2012: The fourth terminal device sends measurement information to the second radio access network device. Correspondingly, the second radio access network device receives the measurement information from the fourth terminal device. The measurement information includes the signal strength of the channel measurement signal received by the fourth terminal device.

[0293] Optionally, the measurement information may be used to request resource configuration of a terminal device for the first radio access network device.
