The present disclosure belongs to the technical field of wireless communication and terminals.

Illustratively, the solutions provided by the embodiments of the present disclosure are applied to UAVs. Illustratively, the solution provided by the embodiments of the present disclosure is applied to low-altitude UAVs.

It should be noted that "low-altitude" in the embodiments of the present disclosure may have different meanings according to the region to which the present disclosure is applied, the type of the terminal, the task to be performed by the terminal, laws and regulations in various places, and so on. For example, for a micro unmanned aerial vehicle, a flight height of less than or equal to 50 meters is referred to as low altitude, for a lightweight unmanned aerial vehicle, a flight height of less than or equal to 120 meters is referred to as low altitude, for mapping, power inspection, etc., the low altitude flight height may be greater than 120 meters, for emergency disaster relief, search and rescue, etc., the low altitude flight height may be greater than 300 meters. The present disclosure is not limited to specific numerical values thereof.

Low-altitude Unmanned Aerial Vehicles (UAVs) are being widely used in transportation, agriculture, industry, entertainment, etc. as new industries, and are being driven to revolutionize. With the increasing number of unmanned aerial vehicles at low altitudes, particularly with the advent of aerial vehicles remotely controlled via cellular communication networks, there is a need to provide a set of methods for effectively identifying and supervising unmanned aerial vehicles in low altitudes.

The 3GPP is used for developing related researches on the communication architecture and the identification requirement of the unmanned aerial vehicle, and unifies the use and the management of the UAV on the standard side. In the use process, the flight route, the altitude, the speed and the like of the UAV have large variation, and new requirements are put forward for the identification and supervision strategies of the aircrafts.

The method for identifying and managing the low-altitude unmanned aerial vehicle can be implemented by adopting sensors carried by the unmanned aerial vehicle, such as cameras and ultrasonic radars, to perform autonomous detection, and performing operations such as obstacle avoidance, flying along a given route and the like according to detection results, and/or adopting a network or control equipment to identify the unmanned aerial vehicle based on feedback information such as radars and flight information, and sending control instructions to perform operations such as flight path, state management and the like.

According to the unmanned aerial vehicle provided by the embodiment of the disclosure, the communication module (such as the cellular communication module/5G communication module) is mounted, and data such as control and images can be transmitted by means of the cellular communication network/mobile communication network, so that the control flexibility of the aerial vehicle is effectively improved, and the moving range and the application field of the aerial vehicle are enlarged. The increase of the maneuvering radius and the remodelling of control of the aircraft are achieved, and particularly as artificial intelligence participates in the control of the aircraft, the safety threat risks of the low-altitude unmanned aircraft to ground and air facilities are also increased, and the aircraft possibly having the risks are identified and managed by technical means.

In the following embodiments, a terminal is illustrated as an Unmanned Aerial Vehicle (UAV), but the present disclosure is not limited thereto. Fig. 2 shows a schematic structural diagram of an unmanned aerial vehicle in an embodiment of the present disclosure. As shown in fig. 2, the unmanned aerial vehicle 40 provided by the embodiment of the present disclosure includes a communication module 41 (may also be referred to as a communication module) and a communication card.

Illustratively, the communication module in the embodiments of the present disclosure includes a 5G communication module. However, the present disclosure is not limited thereto, and may be one or more of a 4G communication module, a 6G communication module, and the like, for example. By means of the communication module, the unmanned aerial vehicle 40 can achieve communication with the network. The network may be, for example, any mobile communication network, such as one or more of a 4G network, a 5G network, a 6G network, or the like.

Illustratively, as shown in fig. 2, the communication card includes a user identity module (UserIdentity Module, UIM) card 42. Illustratively, the UIM card is for a CDMA network. However, the present disclosure is not limited thereto, and any mobile communication network and its corresponding communication card that is covered by the air may be employed.

Illustratively, as shown in fig. 2, the communication module 41 includes a global navigation satellite system (Global Navigation SATELLITE SYSTEM, GNSS) receiving device 411. The GNSS receiver 411 may be configured to obtain location information of the terminal or the unmanned aerial vehicle 40 or the communication module 41.

Illustratively, the communication module 441 includes a GNSS receiver 411. The UIM card may be plugged into an interface on the UAV fuselage and connected with the communication module 441. For example, an eSIM (Embedded Subscriber Identity Module ) card may also be integrated in the communication module 441.

It should be noted that, the acquisition of the above-mentioned position information is not limited to the GNSS receiver in the communication module. In other embodiments, the drone may be positioned by way of on-board positioning and ground detection.

The method shown in fig. 3 may be performed by a communication module in a terminal on which a communication card is provided. As shown in fig. 3, the method provided by the embodiment of the present disclosure includes the following steps.

In S310, location information of the communication module is acquired.

Illustratively, the communication module includes a global navigation satellite system GNSS receiving device. The location information is illustratively acquired by the GNSS receiver apparatus. However, the present disclosure is not limited thereto, and may be, for example, fusion of GNSS and cellular network positioning (OTDOA (Observed TIME DIFFERENCE of Arrival time difference positioning)/ECID (ENHANCED CELL Identification )) to improve positioning accuracy.

The method provided by the embodiment of the disclosure further comprises the steps of acquiring network access information of the network after the terminal is started, and sending a network attachment request to the network according to the network access information so as to access the network.

The network may be, for example, a cellular communication network/mobile communication carrier network.

Illustratively, the network access information is obtained based on an indication of the communication card to access a network and/or pre-configuration information of the communication module.

Illustratively, the communication card may store therein an indication of the access network of user identity information (e.g., handset number, international mobile subscriber identity (International Mobile Subscriber Identity, IMSI), authentication key), etc., for accessing the CDMA network.

The pre-configuration information mainly includes network access information such as an operator, a frequency band, a frequency point priority, and the like, to which the communication module is initially accessed.

Illustratively, when the method provided by the embodiments of the present disclosure is applied to a low-altitude unmanned aerial vehicle, it may also be referred to as a low-altitude unmanned aerial vehicle device identification and management method, the method includes the steps of:

After the UAV equipment is started, the carried communication module is attached to a mobile communication operator network through random access after the target cell is searched by scanning channels in all cellular frequency bands based on the indication of the UIM card to the access network and/or the preconfiguration information of the module, and registration is initiated to the network. Through attachment and registration, the UAV apparatus may enable transmission of data and control signaling over a cellular communication network.

For example, the communication module reads parameters in the UIM card, such as IMSI, PLMN (Public Land Mobile Network, public land mobile network, including operator network code), authentication key (Ki/AKA), and loading module preconfiguration information, such as priority band list, network scanning strategy (full band/scanning by priority), APN (access point name). And then, scanning all supported cellular frequency bands in turn according to the pre-configured frequency band priority. A Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (SSS) are detected on each frequency band, locking the candidate cell. The signal energy peaks are resolved using, for example, FFT (fast fourier transform). The cell with the best signal quality (for example, RSRP > -110dBm and SINR >0 dB) is selected as a target cell. Demodulating the Broadcast Channel (BCH) of the target cell, acquiring MIB (Master Information Block) a bandwidth and a system frame number, and SIB (System Information Block) a PLMN list and a cell access limit. The PLMN in the UIM card is then compared to the PLMN list in the SIB. If so, selecting the target cell, otherwise, continuing scanning. The communication module then sends a Preamble (Preamble) to the base station (e.g., eNB/gNB). The base station replies a Random Access Response (RAR) and allocates a temporary identifier C-RNTI and uplink resources. The communication module sends an RRC connection request (carrying IMSI or GUTI). The base station forwards the IMSI of the communication module to a core network (such as MME/AMF), the core network verifies the UIM card key (Ki or SQN) through the HSS/AuC, and issues an authentication vector (RAND/AUTN), and the communication module calculates a response value RES by using the UIM card. And then carrying out security activation, and negotiating an encryption algorithm and an integrity protection key. The communication module sends an Attach Request (also called network Attach Request) containing device capabilities (supporting NB-IoT/eMTC, etc.), and the requested PDN type (IPv 4/IPv 6). The core network allocates an IP address and establishes a default Bearer, e.g. 4G creates EPS Bearer, 5G creates PDU Session. The registration status of the communication module is updated to registered. Then, activating the preconfigured APN and starting a heartbeat mechanism. The communication module reports a "Network Ready" status to the UAV hosting system to inform that preparation is made for data transmission between the UAV and the Network.

The method provided by the embodiment of the disclosure further comprises measuring the state of the communication signal after the terminal takes off.

And 2, after the UAV equipment takes off, the communication module starts to measure the state of the communication signal. Meanwhile, a GNSS receiving device in the communication module continuously acquires the position information of the communication module.

Illustratively, the location information in the embodiments of the present disclosure refers to any information related to the location of the communication module, the terminal. Illustratively, the location information includes at least latitude and longitude (λ, Φ), and altitude h.

Illustratively, the communication module also compares the location information acquired at different times to obtain the location change status Δd of the terminal/communication module.

The position change state Δd indicates that at least one parameter of longitude, latitude, altitude, etc. of the terminal is changed in different time periods, and Δd is not equal to 0, and any parameter of longitude, latitude, altitude, etc. of the terminal is not changed in different time periods, and Δd is equal to 0.

Illustratively, the communication signal state mainly includes one or more of information such as RSRP (REFERENCE SIGNAL RECEIVED Power ), received signal-to-noise ratio SINR (Signal to Interference plus Noise Ratio), and signal strength of a neighboring cell of the currently located target cell. The main purpose of the communication module to receive the communication signal state is to ensure that the terminal is in the signal coverage environment with the optimal current position, thereby ensuring the communication quality.

After the UAV device takes off, the communication signal state measured by the communication module refers to real-time detection of physical layer and network layer parameters of the cellular network/cellular communication network/mobile communication network connection, which directly affect the communication quality and network stability. Exemplary may include signal strength classes such as RSRP, received signal strength indication RSSI, reference signal received quality RSRQ, signal quality classes such as channel quality indication CQI, network state classes such as physical cell identity PCI/global cell ID ECGI, tracking area code TA, connection state (e.g., RRC state).

In UAV scene, there is high altitude signal attenuation, for example, every 100 m, RSRP attenuation about 20dB (affected by frequency band), at this time the communication module can pre-configure low frequency preferential scanning, doppler frequency shift compensation is needed, for example, when the time speed is 100km/h, 2.6GHz frequency point frequency shift reaches 240Hz, the communication module reports frequency offset value in real time, base station dynamically adjusts and schedules, cell switching delay is sensitive, for example, when switching interruption time is >50ms, control signal loss may be caused.

For example, when RSRP dips >30dB, if the cause is UAV entering behind a building/mountain shelter, UAV autonomous response climbs up or adjusts the way, when SINR continues < -3dB, the cause is co-channel interference (e.g., ground base station overload), UAV autonomous response switches to the alternate operator network, when TA update fails, the cause is cross core network boundary, UAV autonomous response triggers an emergency re-registration (forced detach)/attach).

Illustratively, the 3D signal thermodynamic diagram may be generated by RSRP/SINR data collected in real time, optimizing the subsequent routings. Illustratively, the pictorially code rate between the UAV and the network is dynamically adjusted based on the CQI. Illustratively, the handover request is initiated in advance when the neighbor cell RSRP is 6dB higher than the serving cell and lasts 200 ms.

These signals provide guarantees for flight safety and business continuity.

In S320, it is determined that the terminal is in the first operation state according to the location information of the communication module, and the card type of the communication card is a first type card type.

Illustratively, the card types of the communication card built in the terminal include a first type of card type and a second type of card type. Illustratively, the first type of card includes a non-low-altitude aircraft-specific card and the second type of card includes a low-altitude aircraft-specific card.

Illustratively, the location information includes an altitude, a longitude, and a latitude of the communication module.

The terminal is determined to be in a first operation state according to the position information of the communication module, wherein the terminal is determined to be in operation according to the altitude, the longitude and the latitude, and the terminal is determined to be in the first operation state if the altitude is determined to be within an altitude threshold value.

Illustratively, the first operating state in the embodiments of the present disclosure refers to the terminal being in operation and being at a limited flight altitude and/or limited flight area. Wherein the limited fly height means that the height of the terminal is within a height threshold. The limited flight area refers to a limited flight area, such as a no-fly area, in which the longitude and latitude of the terminal is located.

Illustratively, the method provided by the embodiments of the present disclosure further includes obtaining the height threshold.

The height threshold is obtained periodically from the network and updated dynamically, or the height threshold stored in the communication module is obtained.

Illustratively, when the UAV device accesses the network, the communication module dynamically acquires the altitude threshold information/altitude threshold from the network side periodically (the period may be set according to the actual requirement, and the value of the period is not limited in the disclosure), and dynamically updates the altitude threshold information/altitude threshold. Illustratively, the height threshold includes a first height threshold hmin and a second height threshold hmax. hmax is greater than hmin.

The embodiment of the disclosure can flexibly customize the communication strategy according to the requirements of supervision and the like by dynamically updating the height threshold. The set height threshold is mainly influenced by factors such as network coverage, regional supervision requirements and the like.

In S330, the location information and the identification code of the terminal are reported to the network to which the communication module is connected.

Illustratively, the identity of the terminal comprises an IMEI (International Mobile Equipment Identity ) and/or an IMSI of the terminal.

In S340, a first detach message is sent to the network.

The method provided by the embodiment of the disclosure further comprises the steps of receiving communication transmission resource configuration information transmitted by the network, and sending data to the network at a communication transmission resource corresponding to the communication transmission resource configuration information.

Illustratively, the method provided by the embodiment of the present disclosure further includes receiving a second detach message sent by the network.

The method provided by the embodiment of the disclosure further comprises the step of marking the current frequency point between the communication module and the network as a forbidden access frequency point.

The method provided by the embodiment of the disclosure further comprises the step of starting searching and random access of other frequency points after the interval of the preset time interval t0, wherein the other frequency points do not comprise the current frequency point.

The embodiment of the disclosure can perform limited flight identification:

(1) When the height of the UAV equipment is less than or equal to h and less than or equal to hmax (namely, the height is within a height threshold), the aircraft is judged to be at the low-altitude flying height, and if the communication module detects that any parameter of the longitude and latitude (lambda, phi) and the height h of the UAV equipment is changed, namely, the position change state delta d is not equal to 0, the UAV equipment is judged to be at the low-altitude aircraft in operation, namely, the terminal is judged to be at the first operation state.

For example, the longitude and latitude and the altitude of the UAV apparatus acquired at the current time t2 and the previous time t1 may be compared, and if any one of them changes, Δd+.0, that is, Δd includes whether the longitude changes, whether the latitude changes, and whether the altitude changes.

(2) The communication module reads the type parameter in the UIM card and judges whether the type of the UIM card is a special low-altitude aircraft card. If the card is a special card for a low-altitude aircraft, the UAV equipment/communication module periodically (the specific period size can be set according to actual requirements, the disclosure does not limit the specific period size) reports the position information such as longitude and latitude (lambda, phi) and altitude h of the UAV equipment to the network, and sends the IMEI of the communication module to the network, if the card is not a special card for the low-altitude aircraft, the communication module immediately reports the longitude and latitude (lambda, phi), altitude h and IMEI of the UAV equipment to the network, and then sends a detach message (called a first detach message herein for distinguishing), disconnects (namely, the UAV in the embodiment of the disclosure actively breaks the network) the data bearer between the current communication module and the cellular network, does not search the synchronization signal (such as SSB) of the current frequency point, and does not initiate random access to the network any more within t0 time.

Illustratively, the initial t0 may be on the order of minutes, for example 10 or 15 minutes. Illustratively, with a penalty mechanism, if at a later time the terminal re-accesses the network, the t0 time after re-triggering the rejection (i.e. the communication module sends a detach message and/or the network sends a detach message to the communication module, here called a second detach message for differentiation purposes). The more times the terminal is rejected, the correspondingly incremented t 0.

Illustratively, the value of t0 may be preconfigured in the communication module to minimize network intervention and configuration. The value of t0 may be preconfigured by the terminal or may be issued to the terminal/communication module by the network.

The supervision intensity of the unrestricted flight is small, and only the heartbeat is needed to be maintained with the network, so that the communication module periodically sends longitude, latitude, altitude and other position information to the network, and the restricted flight needs to adopt IMEI and other information to assist in supervision of the terminal.

Illustratively, in restricted flight identification, it is determined not only whether the UAV is at low altitude flight (i.e., within a height threshold), but also whether the UAV is in a restricted flight region, such as a no-fly region, based on its longitude and latitude. For example, if the UAV is less than hmin in height h, but in a no-fly area, the UAV is also considered to be of limited flight. I.e., whether or not the vehicle is in restricted flight based on a combination of the location area and altitude at which the UAV is located.

The disclosed embodiments enable limited flight management.

Illustratively, the network device in the embodiments of the present disclosure includes one or more of a base station, a network and management device, a network element of a core network, and the like. For example, after the network and management device receives information (e.g., location information and IMEI) reported by the UAV device in restricted flight (where "received" includes latitude and longitude and altitude and IMEI sent in both cases: one is sent periodically; the other is sent immediately), based on a location indication of the UAV device, and/or based on a metric and match to the UAV device location information:

(1) For UAV devices that do not break through a location management boundary (e.g., are not in a no-fly area and its boundaries), the network performs a corresponding communication transmission resource configuration to the communication module, i.e., determines communication transmission resource configuration information, and sends the communication transmission resource configuration information to the communication module of the UAV device so that the UAV performs data transmission with the network based on the configured communication transmission resources.

(2) For UAV devices that break through the location management boundary, the network does not configure communication transmission resources to the communication module of the UAV device and sends a detach message (referred to herein as a second detach message) to the communication module while prohibiting the communication module from camping on the current frequency point and no longer responding to the network attach request initiated by the communication module within time t 0.

The method provided by the embodiment of the disclosure further comprises the steps of determining that the terminal is in a second running state according to the position information of the communication module, and periodically reporting the position information to the network.

The terminal is illustratively determined to be in a second operational state based on the location information of the communication module, including determining that the terminal is in operation based on the altitude, longitude, and latitude, and determining that the altitude is less than a first altitude threshold (h < hmin), then determining that the terminal is in the second operational state.

The method provided by the embodiment of the disclosure further comprises the steps of receiving communication transmission resource configuration information transmitted by the network, and sending data to the network at a communication transmission resource corresponding to the communication transmission resource configuration information.

In an embodiment of the disclosure, a communication module in the UAV device may perform unrestricted flight identification by determining that the aircraft is currently in an unrestricted flight altitude and zone when the UAV device flight altitude h < hmin is associated with one or more of a position change status Δd, longitude and latitude (λ, φ) of the UAV device. The UAV device periodically reports longitude and latitude (lambda, phi) and altitude h information of the UAV device to the network through a cellular link.

In determining whether the aircraft is currently in an unrestricted flight altitude and area, the altitude and longitude of the communication may be based. Wherein Δd belongs to a criterion for determining whether to start reporting position information to the network by the communication module. Longitude, latitude and altitude belong to specific information submitted.

The embodiment of the disclosure also provides non-limited flight management, for example, after the network and the management equipment receive the information reported by the UAV equipment, the network and the management equipment perform corresponding communication transmission resource configuration on the communication module of the UAV equipment based on the position indication of the equipment and/or based on the measurement and matching of the position information of the UAV equipment (namely, the network can be matched according to the position reported by the UAV equipment and the preset strategy of the network and determine how the communication resource of the terminal should be configured, such as limiting the access speed of the terminal in a sensitive area, limiting the access of the terminal in a limited area and the like).

In UAV unrestricted flight management, by way of example, "corresponding communication transmission resource configuration is performed on a communication module of UAV equipment based on measurement and matching of position information of UAV equipment" means that a network side dynamically adjusts communication resource configuration by calculating association of spatial relationship of position data and a network preset policy in real time. For example, the network calculates UAV and no-fly zone boundary distances based on the location information, analyzes dynamic characteristics of the location information, such as climb rate (dh/dt: altitude change rate), horizontal speed, heading angle (and course deflection angle), and the like. If the position information is matched with the no-fly zone, triggering communication degradation, matching the air line corridor, enhancing transmission resources, and if the position information is matched with the emergency airspace, starting a backup link. The mechanism realizes the closed-loop control of airspace state-communication resources, ensures that the UAV not only maintains communication efficiency in unrestricted flight, but also meets the safety compliance requirement.

Illustratively, the configured communication transmission resources mainly refer to physical communication resources such as time domain, frequency domain and the like of the UAV for data transmission. After the configured communication transmission resources are sent to the UAV apparatus, the UAV transmits data at the specified time-frequency domain location according to the network configured transmission resources.

The method provided by the embodiment of the disclosure further comprises the steps of determining that the terminal is in the first running state according to the position information of the communication module, and periodically reporting the position information and the identification code of the terminal to the network, wherein the card type of the communication card is a second type of card type (such as a low-altitude aircraft special card/a low-altitude special card).

The method provided by the embodiment of the disclosure further comprises the steps of receiving communication transmission resource configuration information transmitted by the network, and sending data to the network at a communication transmission resource corresponding to the communication transmission resource configuration information.

Illustratively, the method provided by the embodiment of the present disclosure further includes receiving a second detach message sent by the network.

The method provided by the embodiment of the disclosure further comprises the steps of determining that the terminal is in a third running state according to the position information of the communication module, reporting the position information and the identification code of the terminal to the network, and sending a third detach message to the network.

The location information comprises the altitude, longitude and latitude of the communication module, wherein the determination that the terminal is in a third operation state according to the location information of the communication module comprises the determination that the terminal is in operation according to the altitude, longitude and latitude, and the determination that the altitude is greater than a second altitude threshold (h > hmax), and the determination that the terminal is in the third operation state.

The method provided by the embodiment of the disclosure further comprises the step of marking the current frequency point between the communication module and the network as a forbidden access frequency point.

The method provided by the embodiment of the disclosure further comprises the step of starting searching and random access of other frequency points after a preset time interval, wherein the other frequency points do not comprise the current frequency point.

When h > hmax is detected, the communication module immediately reports the longitude and latitude (lambda, phi), the altitude h and the IMEI of the UAV equipment to the network according to the processing thought of the non-low-altitude special card/the non-low-altitude aircraft special card in the limited flight state, and then sends a detach message (called a third detach message) to the network, disconnects the data bearer between the current communication module and the cellular network, does not search for the synchronous signal of the current frequency point any more, and does not initiate random access to the network within the time t 0.

The communication method provided by the embodiment of the disclosure can be applied to the identification management of the low-altitude unmanned aerial vehicle. On the one hand, the dynamic control of the unmanned aerial vehicle in low altitude can be carried out, and real-time information such as the flight state, the communication state and the like of the unmanned aerial vehicle in the low altitude space can be mastered in real time. On the other hand, the comprehensive treatment of the low-altitude airspace is developed, and the unmanned aerial vehicle is dynamically and flexibly managed and controlled under the cooperation of a terminal and a network multiple management and control means.

The low-altitude unmanned aerial vehicle in the embodiment of the disclosure provides a method for identifying and judging the position and state information of the low-altitude unmanned aerial vehicle according to longitude and latitude, altitude, motion state, communication card/user card and other information based on the capability of software and hardware carried in the communication module. For example, a device such as a communication module mounted on a low-altitude unmanned aerial vehicle performs dynamic management such as blocking, limiting access, and reporting device information on a communication link according to its own status information. The communication network is based on the position information reported by the unmanned aerial vehicle and the communication link management request, and is used for carrying out communication resource allocation and boundary management on the unmanned aerial vehicle. The embodiment of the disclosure provides software and hardware implementation of a terminal and a communication module for implementing the method.

As shown in fig. 4, the method provided by the embodiment of the present disclosure may include the following steps.

In S401, the communication module reads the user card or module pre-stored access information.

Illustratively, after the communication module in the aircraft is powered on, SSBs (Synchronization Signal Block, synchronization signal blocks) matching the home network frequency points are synchronized as network access information according to the home network PLMN stored in the user card (included in an indication of the access network in the communication card) or the last resident PLMN information stored in the communication module (included in module pre-stored access information), and random access is initiated to the network.

In S402, the communication module selects home network access registration to acquire altitude threshold information/altitude threshold.

In S403, position information is acquired.

Illustratively, after the UAV takes off, the communication module continuously acquires the position information of longitude and latitude (λ, Φ), altitude h and the like of the communication module through the built-in Beidou or GPS module.

Illustratively, the communication module continuously matches the current height information h according to the height threshold information acquired from the network side or the original height threshold information stored in the communication module.

In S404, the height is determined, if h < hmin, S405 is performed, if hmin is less than or equal to h is less than or equal to hmax, S406 is performed, and if h > hmax, S409 is performed.

In S405, if h < hmin, the communication module periodically reports the location information to the network. Then S411 is performed.

Illustratively, when the communication module detects that the current altitude h does not exceed the minimum altitude information hmin (i.e., the first altitude threshold), the communication module only reports the location information to the network cycle.

In S406, if hmin is equal to or less than h is equal to or less than hmax, the position state/position change state Δd is determined, if Δd is equal to 0, S407 is executed, and if Δd is not equal to 0, S408 is executed.

For example, when the communication module detects that the current altitude h is between the low altitude flight altitude (e.g. 100-300m, i.e. assuming hmin=100m, hmax=300m), it starts to detect whether the longitude, latitude, altitude of the communication module changes, i.e. determines whether Δd is equal to 0, if not, the communication module only reports the location information to the network cycle.

In S407, if the value is equal to 0, the position and state information is periodically reported. Then S411 is performed.

Illustratively, the communication module only reports location information to the network periodically when the user card type belongs to a low-altitude dedicated card. Optionally, the communication module may also periodically report status information, such as the location change status Δd, to the network.

In S408, it is determined whether or not the UIM card is a low-altitude-dedicated card (e.g., a low-altitude-aircraft-dedicated card), if yes, S407 is executed, and if not, S409 is executed.

When it is detected that any parameter of longitude, latitude and altitude of the communication module changes, the communication module reads an EF (ELEMENTARY FILE, basic file) file of the identification card type in the user card through a standard card interface such as ISO7816, and determines whether the card belongs to a low-altitude special card.

In S409, if the low-level dedicated card is not used, the location information and the IMEI/IMSI are reported to the network. And then S410 is performed.

Illustratively, when the user card type belongs to a non-low-altitude special card, the communication module immediately reports the current longitude and latitude, altitude and IMEI/IMSI information of the UAV device to the network. Illustratively, the low-altitude management authority, upon obtaining the above information, alerts law enforcement entities of unauthorized low-altitude flights of the corresponding information.

In S410, a detach is sent to the network while limiting the random access interval. Then S411 (here, after the communication module restarts the access of other frequency points, the transmission resource is configured).

Illustratively, the communication module sends a detach message to the network disconnecting the data bearer between the current communication module and the cellular network.

Illustratively, the communication module marks the current frequency point as a forbidden access frequency point, and subsequently does not search for the SSB synchronization signal of the current frequency point.

Illustratively, the communications module restarts the search for other frequency points and random access attempts after a time interval t0 (e.g., 15 minutes during which the radio frequency functions of the UAV may be turned off).

In S411, the network configures transmission resources (i.e., communication transmission resources).

In the embodiment of the disclosure, for illegal equipment with a non-low altitude special card or a flight altitude h exceeding hmax, a communication module arranged in the UAV equipment immediately reports the position information and IMEI of the UAV equipment, and actively unattached and disabled for a period of time t0 in network searching, so that the communication capacity of the illegal equipment can be blocked, hardware-level permission isolation is realized, the out-of-range UAV loses the communication capacity through frequency point blocking, the UAV is forced to trigger automatic return or landing, and the network is automatically disconnected at the periphery of a sensitive area, a no-fly area and the like, and image return is blocked. And illegal equipment sources can be tracked through the IMEI, and equipment tracing and responsibility tracking are supported. And for the low-altitude special card within the height threshold value and the UAV with h smaller than hmin, the continuous detection of legal equipment is realized by periodically reporting the position information.

Embodiments of the present disclosure may adapt to complex airspace by dynamically updating hmax. If hmax=50 meters is set around the airport, hmax=120 meters is set in the urban area, and hmax=300 meters is set in the industrial area.

The method provided by the embodiment of fig. 5 may be performed by a network device, e.g. a base station and/or a core network element. As shown in fig. 5, the method provided by the embodiment of the present disclosure may include the following steps.

In S510, position information of a communication module in a terminal is received, which is transmitted by the communication module.

In S520, based on the location information, communication transmission resource configuration information or a second detach message is sent to the communication module.

Illustratively, when a second detach message is sent to the communication module, the communication module is prohibited from camping on the current frequency point.

Illustratively, when a second detach message is sent to the communication module, network attach requests initiated in response to the communication module are prohibited for a predetermined time interval.

The method provided by the embodiment of the disclosure further comprises the step of receiving a first detach message or a third detach message sent by the communication module.
