A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable smart device includes full functionality, large size, and can implement full or partial functionality without relying on a smart phone, such as: smart watches or smart glasses and the like, and only focus on a certain type of application functions, and need to be used in cooperation with other devices such as smart phones, such as various smart bracelets for physical sign monitoring, smart jewelry and the like.

In addition, in the embodiment of the present invention, the terminal device may also be a terminal device in an internet of things (IoT) system, where IoT is an important component of future information technology development, and the main technical feature of the present invention is to connect an article with a network through a communication technology, so as to implement an intelligent network with interconnected human-computer and interconnected objects.

In the following, for convenience of understanding and explanation, an unmanned aerial vehicle is taken as an example of a terminal device, and a scheme provided by the application is described in detail.

2. (radio access network, (R) AN) network element: the method and the device are used for providing a network access function for authorized terminal equipment in a specific area, and can use transmission tunnels with different qualities according to the grade of the terminal equipment, the service requirement and the like.

The (R) AN network element can manage radio resources, provide access services for the terminal device, and then complete forwarding of control signals and terminal device data between the terminal device and the core network, and the (R) AN network element can also be understood as a base station in a conventional network.

It should be noted that the "network element" may also be referred to as an entity, a device, an apparatus, a module, or the like, and the present application is not particularly limited. Also, in the present application, for convenience of understanding and explanation, a description of "network element" is omitted in a part of the description, for example, AN (R) AN network element is abbreviated as (R) AN, in which case the "(R) AN network element" is understood as AN (R) AN network element or AN (R) AN entity, and explanation of the same or similar case is omitted below.

For example, the (R) AN network element may comprise AN access device. An access device may provide a service for a cell, and a terminal device communicates with the access device through a transmission resource (e.g., a frequency domain resource or a spectrum resource) used by the cell, where the cell may be a cell corresponding to the access device (e.g., a base station), and the cell may belong to a macro base station or a base station corresponding to a small cell (small cell), where the small cell may include: urban cell (metro cell), micro cell (microcell), pico cell (pico cell), femto cell (femto cell), etc., and these small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-rate data transmission service.

In addition, multiple cells can simultaneously work at the same frequency on a carrier in an LTE system or a 5G system, and under some special scenes, the concepts of the carrier and the cells can also be considered to be equivalent. For example, in a Carrier Aggregation (CA) scenario, when a secondary carrier is configured for a UE, a carrier index of the secondary carrier and a Cell identification (Cell ID) of a secondary Cell operating on the secondary carrier are carried at the same time, and in this case, the concepts of the carrier and the Cell may be considered to be equivalent, for example, it is equivalent that the UE accesses one carrier and one Cell.

Wherein the access device may include one or more antennas. Additionally, the access device can additionally include a transmitter chain and a receiver chain, each of which can comprise a plurality of components associated with signal transmission and reception (e.g., processors, modulators, multiplexers, demodulators, demultiplexers, antennas, etc.), as will be appreciated by one skilled in the art.

Each access device may communicate with multiple terminal devices.

Wherein an access device may transmit data or information to a terminal device over a forward link (also referred to as a downlink) and receive data or information from a terminal device over a reverse link (also referred to as an uplink).

For example, in a Frequency Division Duplex (FDD) system, the forward link may use a different Frequency band than the reverse link, for example.

As another example, in a Time Division Duplex (TDD) system and a Full Duplex (Full Duplex) system, the forward link and the reverse link may use the same frequency band.

Each antenna (or group of antennas consisting of multiple antennas) and/or area designed for communication is referred to as a sector of the access device.

For example, antenna groups can be designed to communicate to terminal devices in a sector of the access device's coverage area. An access device may transmit signals to all terminal devices in its corresponding sector through single-antenna or multi-antenna transmit diversity.

During communication between the access device and the terminal device over the forward link, the transmitting antenna of the access device may also utilize beamforming to improve the signal-to-noise ratio of the forward link.

In addition, mobile devices in neighboring cells may experience less interference when the access device utilizes beamforming to transmit signals to terminal devices scattered randomly through an associated coverage area than when the access device transmits signals to all of its terminal devices through single-antenna or multi-antenna transmit diversity.

At a given time, an access device may be a wireless communication transmitting apparatus and/or a wireless communication receiving apparatus. When sending data, the wireless communication sending device may encode the data for transmission. Specifically, the wireless communication transmitting device may obtain (e.g., generate, receive from other communication devices, or save in memory, etc.) a number of data bits to be transmitted over the channel to the wireless communication receiving device. Such data bits may be contained in a transport block (or transport blocks) of data, which may be segmented to produce multiple code blocks.

When the drone needs to request the mobile network to provide air coverage, or in other words, the drone requests access to an air communication service (i.e., an instance of the first communication service), as shown in fig. 4, the drone (i.e., an instance of the terminal device) may determine the mobile parameters at S110.

The mobility parameters may be used (by the core network device or a third party device) to determine the area or range in which over-the-air coverage needs to be provided.

In the present application, the movement parameter may include, but is not limited to, one or more of the following parameters.

Parameter A: range of motion

For example, the range of movement may include a range in which the drone moves in a horizontal direction, i.e., movement of the drone occurs within the range of movement in the horizontal direction, or in other words, the drone does not move out of the range of movement in the horizontal direction.

For example, the movement range (specifically, the boundary of the movement range) may be a circle, in which case the parameter a may include the coordinates of the center of the movement range, and the radius of the movement range.

For another example, the movement range (specifically, the boundary of the movement range) may be a shape surrounded by a plurality of boundary points connected in sequence, in which case, the parameter a may include coordinates of the plurality of boundary points.

It should be understood that the specific shape of the movement range and the specific expression of the parameter a listed above are merely exemplary, and the present application is not particularly limited as long as the movement ranges determined by the two communication parties (i.e., the drone and the core network device) according to the parameter a can be matched.

For example, the movement range may include a range in which the drone moves in the vertical direction, or a flight height range of the drone, and the movement range in the vertical direction may be defined by a lowest flight height and a highest flight height, for example.

For example, the moving route may be a curve formed by connecting a plurality of path points in sequence, and in this case, the parameter D may include coordinates of the plurality of path points.

And (3) parameter E: direction of movement

In particular, the direction in which the drone is moving.

For example, the parameter D may include coordinates of at least two approach points (e.g., a start point and an end point) passed during the movement, and a precedence order of the drone approach to the at least two approach points.

As another example, the parameter D may include a vector of the moving direction.

Parameter F: speed of movement

Specifically, the speed at which the drone is moving.

For example, the parameter E may include a vector of movement speeds.

Parameter G: current position of unmanned aerial vehicle

By way of example, and not limitation, the current location of the drone may be understood as: the position the drone was in when S110 was executed.

For another example, the current location of the drone may be understood as: the position of the drone when the mobile network is required to provide air coverage services.

It should be understood that the above-listed movement parameters are merely exemplary, and other parameters that can be used to determine at least one area or location of the path of the drone during movement are within the scope of the present application.

By way of example and not limitation, the movement parameters may be input to the drone by a user of the drone.

Alternatively, the movement parameter may be obtained by analyzing the flight path by the drone.

Alternatively, the movement parameter may be obtained by analyzing an instruction input by the controller (or the remote controller or the manipulator) by the drone.

It should be understood that the above-listed methods and processes for determining the movement parameter by the drone are only exemplary, and the application is not limited thereto, and other schemes for determining the movement parameter by the drone are within the scope of the application.

Optionally, the drone may also determine the assistance information # 1.

In this application, the air interface configuration parameter may include, but is not limited to, one or more of the following parameters:

bandwidth configuration

In this embodiment of the present invention, the bandwidth configuration may refer to a usage width of a frequency domain resource required by an air interface, which is taken as an example and is not limited to, and may refer to a minimum frequency domain resource width required by the air interface, or a number of subcarriers, for bandwidth configuration corresponding to a broadband transmission service; the bandwidth configuration corresponding to the narrowband transmission service may refer to a maximum frequency domain resource width required by an air interface, or a number of subcarriers.

For example, the measurement unit of the transmission power may include, but is not limited to, any one of the following units:

power (W): versus a linear level of 1 watt (Watts).

Parameter I: expected transmission delay of unmanned aerial vehicle

That is, the access device and the core network device may adjust or select the air interface configuration parameter according to the parameter I, so that the communication delay between the access device and the drone meets (e.g., is less than or equal to) the transmission delay expected by the drone.

Optionally, the auxiliary information #1 may further include some or all of the above-mentioned movement parameters.

That is, the access device and the core network device can calculate the distance between the access device and the unmanned aerial vehicle according to the mobile parameters, and then adjust or select the air interface configuration parameters according to the distance, so that the communication rate between the access device and the unmanned aerial vehicle meets the transmission rate expected by the unmanned aerial vehicle, or the communication delay between the access device and the unmanned aerial vehicle meets the transmission delay expected by the unmanned aerial vehicle.

Optionally, the drone may also determine assistance information # 2.

The assistance information #2 may be used (for the access device or the core network device) to determine parameters of a communication time (or, in other words, a communication period, a communication start time or a communication end time) of the air communication service.

By way of example and not limitation, in the present application, the assistance information #2 may include, but is not limited to, the following parameters:

parameter J: the movement time.

For example, the movement time of the drone may include a movement start time of the drone and a movement end time of the drone.

Alternatively, the movement time of the drone may include a movement start time of the drone and a movement duration of the drone.

Therefore, the access device and the core network device can determine the time period when the unmanned aerial vehicle is located in the coverage range of the cell provided by the access device or the access device according to the parameter J, and further can provide the air coverage service in the time period.

Optionally, the auxiliary information #2 may further include some or all of the above-mentioned movement parameters.

That is, the access device and the core network device may calculate a time period during which the drone is located within a coverage area of the access device or a cell provided by the access device according to the mobile parameter, and may further provide an air coverage service in the time period.

Also, the drone may send request information # a (i.e., an instance of the first message) to the first network device (i.e., the core network device, e.g., the UCF described above) (e.g., via the access device or the core network device, e.g., the AMF), which may be used to indicate that the drone requests the mobile network to provide over-the-air coverage, or, in other words, that the drone requests access to over-the-air communication traffic (i.e., an instance of the first communication traffic).

It should be noted that the first network device may also be an AMF, in which case the drone may send the request message # a to the first network device.

And, the request information # a may include the above-mentioned movement parameter.

Alternatively, the request message # a and the mobility parameter may be carried in the same message or signaling.

Optionally, the request information # a may also carry the auxiliary information #1 or the auxiliary information # 2.

It should be understood that the mobility parameter and the request message # a may also be carried in different signaling, or the mobility parameter and the request message # a may also be transmitted asynchronously, and the application is not particularly limited.

The mobility parameter and the auxiliary information #1 or #2 may be carried by different signaling, or the mobility parameter and the auxiliary information #1 or #2 may be transmitted asynchronously, and the present application is not particularly limited.

The request information # a and the auxiliary information #1 or #2 may be carried by different signaling, or the request information # a and the auxiliary information #1 or #2 may be transmitted asynchronously, and the present application is not particularly limited.

In this application, the request message # a may be carried in a predetermined message or signaling.

Fig. 5 shows an example of a message carrying request information # a of the present application, and as shown in fig. 5, the message may include, but is not limited to, the following fields (or domains):

a message type field, for example, information carried by the message type field may indicate that the type of the message is an N1 message type;

a time of flight field, for example, the information carried by the time of flight field may indicate the start time and the end time of the flight;

the communication requirement field, for example, may carry information indicating uplink and downlink rate and delay requirements of the terminal requesting communication.

By way of example and not limitation, the preset message or signaling may include, but is not limited to: non-access stratum (NAS) messages.

Thereafter, the first network device (e.g., UCF) may determine at least one target access device from the plurality of access devices based on the request information # a.

Specifically, at S120, the first network device may determine the area # a (i.e., an example of the first area) based on the mobility parameter.

The area # a is an area where communication coverage needs to be provided.

For example, the first network device may determine the range in the horizontal direction of the area # a according to the horizontal movement range indicated by the above-described parameter a (i.e., the movement range), i.e., the first network device may cause the area # a to include the horizontal movement range indicated by the parameter a.

For another example, the first network device may determine the altitude of the area # a according to the flying altitude indicated by the parameter a (i.e., the moving range), that is, the first network device may make the difference between the altitude of the area # a and the altitude indicated by the parameter a within a preset difference range.

For another example, the first network device may determine the area # a such that the area # a (specifically, the range in the horizontal direction of the area # a) includes the movement destination of the drone, based on the above-described parameter B (i.e., the movement destination).

For another example, the first network device may determine the area # a such that the area # a (specifically, the range in the horizontal direction of the area # a) includes the moving origin of the drone, based on the parameter C (i.e., the moving origin) described above.

For another example, the first network device may determine the area # a such that the area # a (specifically, the range in the horizontal direction of the area # a) includes the approach point on the movement route of the drone, according to the above-described parameter D (i.e., the movement route).

For another example, the first network device may calculate the movement route of the drone according to the parameter D (i.e., the movement direction), the parameter E (the movement speed), and the parameter F (i.e., the current location), and further determine the area # a, so that the area # a (specifically, the range in the horizontal direction of the area # a) includes the approach point on the movement route of the drone.

It should be noted that, in this application, the first network device may summarize the mobile parameters reported by the multiple drones, and determine the area # a according to the multiple mobile parameters, for example, the area # a may include an approach point on a flight route of each of the multiple drones.

Thereafter, the first network device may determine the target access device based on the area # a.

By way of example and not limitation, in the present application, the first network device may perform the determination process of the target access device in any one of the following manners.

Mode A

The first network device may acquire coverage information (hereinafter, referred to as information #1 for ease of understanding and explanation) of a plurality of access devices or cells (of the access devices) in the communication system.

Wherein the information #1 may be used to indicate the coverage of the access device or cell.

For example, in the present application, a network element (i.e., a third party device, such as OAM) for periodically collecting information #1 of each access device or cell may be configured in the communication system, so that, at S131, the first network device may obtain the information #1 from the third party device.

For another example, in the present application, the first network device may establish a communication connection with each access device, so that the first network device may obtain the information #1 from the access device.

Thus, in S132, the first network device may determine the target receiving device according to the area #1 and the coverage area of each access device or cell indicated by the information #1, so that the coverage area of the target access device or the cell of the target access device includes (or can cover) the area # a.

Wherein the information #2 may be used to indicate the communication capability of the access device or cell.

For example, the communication capability may include a capability (denoted as capability #1) whether an over-the-air service (i.e., an example of the first communication service) can be provided.

In this case, the first network device may first select an access device (denoted as alternative access device #1) capable of providing an over-the-air service from a plurality of access devices or cells in the communication system based on the information # 2.

Further, the first network device may select an access device (denoted as an alternative access device #3) that can satisfy the transmission delay desired by the drone from among a plurality of access devices or cells in the communication system, based on the information # 2.

Thereafter, the first network device may determine a target access device from the alternative access device #3 according to the information # 1.

It should be understood that the communication capability may include one or more of capability #1, capability #2, and capability #3, and that depending on the particular capability included in the communication capability, the alternative receiving devices selected should simultaneously meet the requirements for that particular capability.

At S134, the first network device may transmit information of the area # a to the third party device.

Thus, at S136, the third party device may determine an alternative access device according to the area # a and the coverage area of each access device or cell in the communication system, so that the coverage area of the alternative access device or the cell of the alternative access device includes (or can cover) the area # a.

Optionally, a set of access networks corresponding to each of a plurality of geographic areas may also be stored in the third party device, where each set of access networks may include one or more access networks (e.g., access devices or cells), and in this case, the third party device may determine an alternative access device according to the area # a and the set of access networks corresponding to each geographic area, so that the alternative access device or the cell of the alternative access device includes an access network in the set of access networks corresponding to the geographic area # a.

Thereafter, the third party device may send information (e.g., device identification or cell identification) of the alternative access device (or the cell provided by the alternative access device) to the first network device S138.

Thus, at S139, the first network device may determine a target receiving device from the alternative access devices, for example, the target receiving device may be a part of the alternative access devices or all of the alternative access devices.

Optionally, before the third party device determines the target access device according to the information #1, the third party device may further obtain capability information of a plurality of access devices or cells (of the access devices) (hereinafter, referred to as information #2 for ease of understanding and explanation).

In this case, the third party device may first select an access device (denoted as alternative access device #1) capable of providing an over-the-air service from a plurality of access devices or cells in the communication system based on the information # 2.

Thereafter, the third party device may determine the target access device from the alternative access device #1 based on the information # 1.

In this case, the third party device may also determine the desired transmission rate of the drone, e.g. the first network device may send a parameter H to the third party device indicating the desired transmission rate of the drone.

Further, the third party device may select an access device (denoted as an alternative access device #2) capable of satisfying the transmission rate desired by the drone from among a plurality of access devices or cells in the communication system, according to the information # 2.

In this case, the third party device may also determine an expected transmission latency of the drone, e.g. the first network device may send a parameter I to the third party device indicating the expected transmission latency of the drone.

Further, the third-party device may select an access device (denoted as an alternative access device #3) that can satisfy the transmission delay desired by the drone from among a plurality of access devices or cells in the communication system, based on the information # 2.

Thereafter, the third party device may determine the target access device from the alternative access device #3 based on the information # 1.

It should be noted that, in this application, the first network device may summarize the mobile parameters reported by the multiple drones, and determine the target access device according to the multiple mobile parameters, for example, the coverage area of the target access device may include a passing point on a mobile route of each of the multiple drones.

In addition, in this case, when the first network device is the UCF, the AMF may send the first mobility parameters reported by the multiple drones to the UCF through the same message, or the AMF may send the first mobility parameters reported by the multiple drones to the UCF through different messages.

At S140, the first network device (e.g., UCF) may send network coverage requirement information to the target access device, where the network coverage requirement information may be used to instruct the target access device to turn on an air coverage function, or in other words, the network coverage requirement information may be used to instruct the target access device to provide an air coverage service.

Optionally, the target access device may include multiple access devices, in this case, the network coverage requirement information may be multiple, and each network coverage requirement information is used to indicate that one target access device provides network coverage, in this case, the first network device may send the multiple pieces of network coverage requirement information to the access control device through the same message, and the access control device sends the multiple pieces of network coverage requirement information to the corresponding access devices respectively; alternatively, the first network device may respectively carry the plurality of network coverage requirement information through a plurality of messages.

Accordingly, the target access device may provide an over-the-air coverage service according to the network coverage requirement information S150.

Optionally, in this application, an air interface configuration of the target access device may also be determined.

By way of example and not limitation, the air interface configuration may be determined in any of the following manners.

Mode C

The first network device may also determine, according to the auxiliary information #1, an air interface configuration of the target access device, specifically, an air interface configuration parameter.

For example, the first network device may adjust or select the air interface configuration parameter according to the parameter H, so that the communication rate between the access device and the drone satisfies (e.g., is greater than or equal to) the transmission rate expected by the drone.

For another example, the first network device adjusts or selects the air interface configuration parameter according to the parameter I, so that the communication delay between the access device and the drone meets (e.g., is less than or equal to) the transmission delay expected by the drone.

For another example, the first network device may calculate a distance between the access device and the unmanned aerial vehicle according to the mobile parameter, and then adjust or select the air interface configuration parameter according to the distance, so that a communication rate between the access device and the unmanned aerial vehicle satisfies a transmission rate expected by the unmanned aerial vehicle, or a communication delay between the access device and the unmanned aerial vehicle satisfies a transmission delay expected by the unmanned aerial vehicle.

Accordingly, the first network device may send configuration information # a (i.e., an example of the first configuration information) indicating the air interface configuration parameters determined as described above to the target access network device.

Thus, the target access network device may provide an air coverage service according to the network coverage requirement information, and determine an air interface configuration parameter (i.e., an example of a communication parameter) of the air coverage service according to the configuration information # a.

It should be noted that, in the present application, the network coverage requirement information may include the configuration information # a, or the network coverage requirement information and the configuration information # a may be sent synchronously.

Alternatively, the network coverage requirement information and the configuration information # a may be carried in different messages or signaling, or the network coverage requirement information and the configuration information # a may be sent asynchronously.

It should be noted that, in this application, the first network device may summarize the auxiliary information #1 reported by the multiple unmanned aerial vehicles, and determine the air interface configuration of the target access device according to the multiple auxiliary information #1, for example, the air interface configuration of the target access device may be set to meet a communication delay requirement of an unmanned aerial vehicle with the highest delay requirement among the multiple unmanned aerial vehicles, or the air interface configuration of the target access device may be set to meet a transmission rate requirement of an unmanned aerial vehicle with the highest transmission rate requirement among the multiple unmanned aerial vehicles.

In addition, in this case, when the first network device is the UCF, the AMF may send the first auxiliary parameters reported by the multiple drones to the UCF through the same message, or the AMF may send the first auxiliary parameters reported by the multiple drones to the UCF through different messages.

Mode D

The first network device may send the aforementioned assistance information #1 to the target access device.

The target access device may determine, according to the auxiliary information #1, an air interface configuration of the target access device, specifically, an air interface configuration parameter.

For example, the target access device may adjust or select the air interface configuration parameter according to the parameter H, so that the communication rate between the access device and the drone satisfies (e.g., is greater than or equal to) the transmission rate expected by the drone.

For another example, the target access device adjusts or selects the air interface configuration parameter according to the parameter I, so that the communication delay between the access device and the drone meets (e.g., is less than or equal to) the transmission delay expected by the drone.

For another example, the target access device may calculate a distance between the access device and the unmanned aerial vehicle according to the mobile parameter, and then adjust or select the air interface configuration parameter according to the distance, so that a communication rate between the access device and the unmanned aerial vehicle satisfies a transmission rate expected by the unmanned aerial vehicle, or a communication delay between the access device and the unmanned aerial vehicle satisfies a transmission delay expected by the unmanned aerial vehicle.

Therefore, the target access network device may provide the air coverage service by using the determined air interface configuration parameter according to the network coverage requirement information.

Optionally, in this application, a communication time of the target access device, specifically, a time period for providing an air coverage service, may also be determined.

By way of example and not limitation, the communication time may be determined in any of the following ways.

Mode E

The first network device may also determine a communication time of the target access device, specifically, a time period for providing an air coverage service, according to the auxiliary information # 2.

For example, the first network device may determine, according to the parameter J, a time period during which the drone is located within the coverage of the target access device or the cell provided by the target access device.

For another example, the first network device may calculate, according to the mobility parameters, a time period during which the drone is located within the coverage area of the target access device or a cell provided by the target access device.

Thus, the first network device may transmit configuration information # B (i.e., an example of the second configuration information) indicating the communication period determined as described above to the target access network device.

For example, the configuration information # B may be used to indicate the start time and the end time of the communication period, or the configuration information # B may be used to indicate the start time and the duration of the communication period.

Accordingly, the target access network device may provide the over-the-air service according to the network coverage requirement information, and determine the communication time period of the over-the-air service according to the configuration information # B.

It should be noted that, in the present application, the network coverage requirement information may include the configuration information # B, or the network coverage requirement information and the configuration information # B may be sent synchronously.

Alternatively, the network coverage requirement information and the configuration information # B may be carried in different messages or signaling, or the network coverage requirement information and the configuration information # B may be sent asynchronously.

It should be noted that, in this application, the first network device may summarize the auxiliary information #2 reported by the multiple drones, and determine the communication time of the target access device according to the multiple auxiliary information #2, for example, may determine a starting time at which the target access device provides the air coverage service according to a time when the first drone enters the coverage area of the target access device, and determine an ending time at which the target access device provides the air coverage service according to a time when the last drone leaves the coverage area of the target access device.

Mode F

The first network device may send the aforementioned assistance information #2 to the target access device.

The target access device may determine the communication time period during which the target access device provides the air coverage service according to the auxiliary information # 2.

For example, the target access device may adjust or select the air interface configuration parameter according to the parameter G, so that a communication rate between the access device and the drone satisfies (e.g., is greater than or equal to) a transmission rate expected by the drone.

For example, the target access device may determine, according to the parameter J, a time period during which the drone is located within the coverage of the target access device or the cell provided by the target access device.

For another example, the target access device may calculate, according to the movement parameter, a time period during which the drone is located within a coverage area of the target access device or a cell provided by the target access device.

Accordingly, the target access network device can provide the over-the-air coverage service according to the network coverage requirement information in the communication time period determined as described above.

Optionally, after receiving the network coverage requirement information, the target access device may further send feedback information #1 to the first network device, where the feedback information #1 may be used to indicate that the target access device is capable of providing an air coverage service.

The first network device may send feedback information #2 to the drone after receiving the feedback information #1, where the feedback information #2 may be used to indicate that the drone may access the first communication service.

In the above description, the processing procedure of the terminal device is described by taking the unmanned aerial vehicle as an example, but the terminal device of the present invention is not limited to this, and the terminal device may be any mobile device.

For example, the terminal device may also comprise an unmanned automobile or the like, in which case the air coverage service may be replaced by a ground coverage service.

As another example, the terminal device may also include an unmanned ship or the like, in which case the air coverage service may be replaced with a marine coverage service.

Furthermore, although the scheme that the drone transmits the request information # a to the first network device has been described above, the present application is not limited to this, and the request information # a may be transmitted to the first network device by a control device (for example, a remote controller or a control device) of the drone (or another mobile device) or a drone server, or S110 may be initiated by a control device (for example, a remote controller or a control device) of the drone (or another mobile device) or a drone server.

In a communication technology, in order to ensure the communication coverage of a mobile terminal device, each access device in a communication system needs to start a communication coverage function, thereby causing the resource waste of the access device without the arrival of the terminal device in the coverage.

In contrast, according to the scheme provided by the present application, by enabling the terminal device to report the mobility parameter, enabling the first network device to determine the target access device that needs to provide the communication service for the terminal device according to the mobility parameter, and controlling the target access device to start the communication coverage function, unnecessary resource waste of the access device in which the terminal device does not arrive within the coverage area can be avoided.
