Technical Field

The present invention relates to the field of communications, and in particular, to a data transmission method and apparatus.

Background

At present, in order to improve the efficiency of inspection operation and reduce the pressure of manual inspection, a robot can be used for intelligent inspection instead of manual inspection.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that, in the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "such as" in an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

It should be noted that in the embodiments of the present invention, "of", "corresponding" and "corresponding" may be sometimes used in combination, and it should be noted that the intended meaning is consistent when the difference is not emphasized.

For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, the words "first", "second", and the like are used for distinguishing the same items or similar items with basically the same functions and actions, and those skilled in the art can understand that the words "first", "second", and the like are not limited in number or execution order.

The fifth generation mobile communication (5 g) technology has the characteristics of high bandwidth, ultra-reliability, low time delay, mass information access and the like. The 5G technology is used for data interaction, so that the technical fields with higher requirements on network delay are greatly developed. For example, when the robot is used for polling, data collected by various sensors of the robot needs to be transmitted through the communication system, so that the reliability, low time-delay and coverage capability of the communication system are key factors influencing the polling efficiency of the robot. And the 5G technology can well meet the requirements on the performance of a communication network when the robot and the control equipment perform data interaction. And the robot based on the 5G technology can not only complete the inspection task in the traditional sense, but also realize the comprehensive inspection services such as man-machine interaction, instrument reading acquisition, intelligent navigation, inspection line planning and the like.

Generally, a robot transmits data at a fixed rate while interacting with a control device. When the robot is used for inspection, the data transmission quality between the robot and the control equipment is easily influenced by environmental factors of an inspection site. When the environment of the inspection site is complex, which causes poor network quality between the robot and the control equipment, the service executed by the robot is affected. For example, when the robot handles a service with high requirements on time delay (such as a real-time video transmission service), the robot can transmit real-time video data to the control device at a high rate. However, due to poor network quality between the robot and the control device, if the real-time video service is still transmitted at the fixed rate, the video frame is delayed, which does not meet the requirement of the real-time video return service on the data transmission rate, and causes the quality of the real-time video return service to be reduced or failed. For another example, the 5G technology uses millimeter waves to transmit data, and millimeter waves have the characteristics that the higher the transmission rate is, the faster the signal quality is attenuated. When the robot is far away from the communication base station, in order to reduce the attenuation of data transmission between the robot and the communication base station, the robot can transmit service data at a lower rate.

In order to solve the problem of poor service data transmission quality caused by adopting fixed-rate data transmission, the embodiment of the invention provides a data transmission method, aiming at different services, control equipment acquires parameters of the environment where terminal equipment is located, determines a reference rate according to the parameters of the environment where the terminal equipment is located, determines an offset rate according to the service type, adjusts the reference rate according to the offset rate to obtain a target rate, and transmits control information at the target rate. Similarly, the terminal device determines a reference rate according to the parameters of the environment where the terminal device is located, determines an offset rate according to the service type, adjusts the reference rate according to the offset rate to obtain a target rate, and sends service information at the target rate. Therefore, the successful transmission of the data is ensured, the waste of network resources is reduced, and the high-quality transmission of the service instruction and the service data is realized.

Next, embodiments of the present application will be described in detail with reference to the drawings.

Fig. 1 is a schematic architecture diagram of a communication system applied to an embodiment of the present application.

As shown in fig. 1, the communication system includes a terminal apparatus 101, an access apparatus 102, a 5G network 103, an access apparatus 104, and a control apparatus 105. The terminal device 101 is connected with the access device 102 in a wireless mode, the access device 102 is connected with the 5G network 103 in a wired mode, the access device 104 is connected with the 5G network 103 in a wired mode, and the control device 105 is connected with the access device 104 in a wired or wireless mode.

The terminal device 101 may be located at the inspection site, and is configured to receive a service instruction sent by the control device 105 and forwarded by the access device 102. The terminal device 101 executes the service instruction, and transmits service data generated by executing the service instruction to the control device 105 through the access device 102 and the 5G network. In the embodiment of the present invention, the terminal device 101 may be a robot.

The access device 102 is configured to receive a service instruction sent by the control device 105 through the access device 104 and the 5G network 103, and forward the service instruction to the terminal device 101. The access device 102 is further configured to receive service data sent by the terminal device 101, and forward the service data to the control device 105 through the 5G network 103 and the access device 104.

The access device 104 is configured to receive the service instruction sent by the control device 105, and forward the service instruction to the access device 102 through the 5G network 103. The access device 104 is further configured to receive service data sent by the terminal device 101 through the access device 102 and the 5G network 103, and forward the service data to the control device 105.

The 5G network 103 is used to transmit data exchanged between the terminal apparatus 101 and the control apparatus 105.

The control device 105 may be a control center located in a background, or may be a handheld terminal or a vehicle-mounted terminal located in an inspection site. When the control device 105 is located at the inspection site, its position may be fixed or may be movable. The control device 105 is configured to issue a service instruction to the terminal device 101 and receive service data generated by the terminal device 101 executing the service instruction.

In some embodiments, when the control device is a handheld terminal or a vehicle-mounted terminal located in the inspection site, the control device 105 and the terminal device 101 are usually located in a cell covered by the same base station because the control device 105 and the terminal device 101 are located at a short distance, and the access device 102 and the access device 104 may be the same device.

Fig. 1 is a schematic diagram, and other network devices, such as a wireless relay device, may be further included in the communication system, which is not shown in fig. 1. The embodiments of the present application do not limit the number of the terminal device 101, the access device 102, the access device 104, and the control device 105 included in the communication system.

Fig. 2 is a diagram illustrating a data transmission method according to an embodiment of the present invention. Here, the description will be given taking an example in which the control device 105 transmits a service instruction to the terminal device 101, and the terminal device 101 transmits data of the first service generated in response to the service instruction to the control device 103. As shown in fig. 2, the method includes the following steps.

S201, the terminal device 101 generates data of the first service according to the instruction of the first service.

In some embodiments, the terminal device 101 may receive the first control information from the control device 103, the first control information including an instruction of the first service. The first control information may be disposed in a payload in the message. The terminal device 101 may parse the first control information to obtain an instruction of the first service included in the first control information, and the terminal device 101 executes the instruction of the first service to generate data of the first service. For example, the instruction of the first service is to instruct the terminal device 101 to collect the reading of the meter, and the terminal device 101 executes the instruction to read the reading of the meter and generate data including the reading of the meter; for another example, the instruction of the first service is an instruction that instructs the terminal apparatus 101 to perform a forward movement of ten meters, the terminal apparatus 101 executes the instruction, and moves 10 meters forward, after the execution of the service is completed, the terminal apparatus 101 may generate a response message, where the response message is an instruction that instructs the terminal apparatus 101 to perform the first service, and the response message may be data generated by the instruction that instructs the terminal apparatus 101 to perform the first service.

S202, the terminal device 101 obtains parameters of the environment where the terminal device is located.

In some embodiments, the parameters of the environment may include a temperature parameter, a humidity parameter, a distance parameter, and a device number parameter.

The temperature parameter is used to indicate the temperature of the environment in which the terminal device 101 is located. Optionally, the terminal device 101 may integrate a temperature sensor, and the terminal device 101 obtains the temperature of the environment where the terminal device 101 is located through the integrated temperature sensor.

The humidity parameter is used to indicate the humidity of the environment in which the terminal apparatus 101 is located. Optionally, the terminal device 101 may integrate a humidity sensor, and the terminal device 101 acquires the humidity of the environment through the integrated humidity sensor.

The distance parameter is used to indicate the distance between the terminal device 101 and the access device 102. Alternatively, the terminal apparatus 101 may integrate a positioning device, for example, a Global Positioning System (GPS). The terminal device 101 determines the coordinates of the location of the terminal device through the integrated GPS, and calculates the distance between the terminal device and the access device 102 according to the coordinates of the location of the access device 102.

The device number parameter is used to indicate how many devices the control device 105 corresponding to the terminal device 101 controls in common. In some embodiments, the control device 105 may control a plurality of terminal devices to perform the polling task at the same time, and thus the number of devices may be an integer greater than or equal to 1. The number of devices may be requested by the terminal device 101 to the control device 105, requesting the control device 105 to feed back the number of devices to which it is connected to the terminal device 101.

And S203, the terminal device 101 determines the reference rate according to the parameters.

As shown in fig. 3, the step of determining the reference rate by the terminal device 101 according to the parameters specifically includes steps S2031 to S2035:

s2031, the terminal apparatus 101 determines a first rate according to the temperature.

Generally, electronic components such as diode, triode and integrated circuit are contained in electronic equipment, and electronic components are easily influenced by ambient temperature, and consequently, under different ambient temperatures, for example, when ambient temperature is higher, the heat that electronic equipment work produced can not distribute effectively, leads to electronic equipment to be burnt out, and when ambient temperature was lower, electronic equipment's energy consumption can greatly increased, leads to the unable continuous work of electronic equipment. Therefore, a rate may be set for each ambient temperature, and at each ambient temperature, the terminal device 101 transmits data using the corresponding rate, thereby ensuring that the terminal device 101 can operate normally. For example, when the outside temperature is high, the terminal device 101 may transmit data at a lower rate to reduce the power and heat generation of the terminal device 101, thereby ensuring that the terminal device 101 can operate normally in a high-temperature environment. Conversely, when the outside temperature is low, data may be transmitted at a higher rate to increase the power and heat generation of the terminal device 101, thereby ensuring that the terminal device 101 can also operate normally in a low-temperature environment.

Generally, the temperature-rate correspondence can be obtained through multiple experiments.

In some embodiments, the temperature-rate correspondence may be presented in the form of a table, i.e., table 1 is a temperature-rate table, which presents the temperature-rate correspondence. The temperature-rate table includes a temperature column and a rate column. Wherein, the temperature column records at least one temperature, and the speed column records the speed corresponding to each temperature.

TABLE 1

Temperature of	Rate of change
		T1	V11
T2	V12
		T3	V13
…	…

As can be seen from Table 1, the rate corresponding to the temperature T1 is V11; the rate corresponding to the temperature T2 is V12; the temperature T3 corresponds to a rate V13.

It should be noted that table 1 only shows a storage form of the correspondence between the temperature and the rate in the storage device in a table form, and is not limited to the storage form of the correspondence between the temperature and the rate in the storage device.

In some embodiments, terminal device 101 may obtain the first rate at the temperature of the environment in which terminal device 101 is located according to a temperature-rate table. The terminal 101 may obtain the temperature-rate table from the control center through the network, or may be introduced into the terminal by a worker through other mobile devices (e.g., a usb disk).

Specifically, the terminal device 101 obtains the temperature of the current environment, then queries a temperature-rate table according to the temperature, determines the rate corresponding to the temperature in the temperature-rate table, and determines the rate as the first rate.

Understandably, the first rate can be a rate at which the terminal device 101 can be guaranteed to normally operate when in the environment of the above-mentioned temperature.

S2032, the terminal apparatus 101 determines a second rate according to the humidity.

According to the electromagnetic wave theory, the greater the conductivity of the medium transmitting the electromagnetic wave, the greater the attenuation of the electromagnetic wave during transmission. For example, air may be a medium that transmits electromagnetic waves. Since air humidity is proportional to electrical conductivity, air humidity is also proportional to attenuation of electromagnetic waves. And the transmission rate of electromagnetic waves is inversely proportional to the attenuation. One rate may be set for each humidity at which the terminal apparatus 101 transmits data using the corresponding rate, thereby improving the quality of data transmission. For example, when the external environment humidity is high, in order to reduce the influence of attenuation on the data transmitted by the terminal device 101, the terminal device 101 may transmit the data at a lower transmission rate; when the external environment humidity is low, the terminal device 101 may transmit data at a higher rate in order to reduce the delay of data transmitted by the terminal device 101.

Generally, the humidity-rate correspondence can be obtained through multiple tests.

In some embodiments, the humidity-rate correspondence may be presented in the form of a table, i.e., table 2 is a humidity-rate table, which presents humidity-rate correspondence. The humidity-rate table includes a humidity column and a rate column. Wherein, the humidity column records at least one humidity, and the speed column records the speed corresponding to each humidity.

TABLE 2

Humidity	Rate of change
		W1	V21
W2	V22
		W3	V23
…	…

As can be seen from table 2, the rate corresponding to the humidity W1 is V21; the speed corresponding to the humidity W2 is V22; the humidity W3 corresponds to a rate V23.

It should be noted that table 2 only shows a storage form of the correspondence between humidity and rate in the storage device in a table form, and is not limited to the storage form of the correspondence between humidity and rate in the storage device.

In some embodiments, terminal device 101 may obtain the rate at the current humidity based on a humidity-rate table. The terminal device may obtain the humidity-rate table from the control center through the network, or the humidity-rate table may be introduced into the terminal device 101 by a worker through other mobile devices (e.g., a usb disk).

Specifically, the terminal device 101 obtains the humidity of the current environment, then queries a humidity-rate table according to the humidity, determines a rate corresponding to the humidity in the humidity-rate table, and determines the rate as the second rate.

It will be appreciated that the second rate may be a rate that improves the quality of data transmission when the terminal device is in an environment of humidity as described above.

S2033, the terminal apparatus 101 determines a third rate according to the distance.

Since electromagnetic waves are attenuated in the transmission process, when the distance between the terminal device 101 and the access device 102 is long, the attenuation is severe when data exchange occurs between the terminal device 101 and the access device 102. The 5G technology adopts millimeter waves for communication, and the millimeter waves have the characteristic of higher speed and faster attenuation. A rate may be set for each distance, and at each distance, the terminal device 101 transmits data using the corresponding rate, thereby reducing attenuation and improving the operating efficiency of the terminal device 101. Therefore, when the distance is longer, the terminal device can transmit data at a lower transmission rate to improve the attenuation during data transmission.

In general, the distance-velocity correspondence can be obtained through multiple experiments.

In some embodiments, the distance-rate correspondence may be presented in the form of a table, i.e., table 3 is a distance-rate table, which presents the temperature-rate correspondence. The distance-to-speed table includes a distance column and a speed column. The distance column records at least one distance, and the speed column records the speed corresponding to each distance.

TABLE 3

Distance between two adjacent plates	Rate of speed
		S1	V31
S2	V32
		S3	V33
…	…

As can be seen from table 3, the velocity corresponding to the distance S1 is V31; the speed corresponding to the distance S2 is V32; the distance S3 corresponds to a velocity V33.

It should be noted that table 3 only shows a storage form of the correspondence between the distance and the speed in the storage device in a table form, and is not limited to the storage form of the correspondence between the distance and the speed in the storage device.

In some embodiments, terminal device 101 may obtain the third rate at the current distance according to the distance-rate table. The terminal device may obtain the distance-rate table from the control center through the network, or may be introduced into the terminal device 101 by a worker through another mobile device (e.g., a usb disk).

Specifically, the terminal device 101 obtains a distance from the access device 102, queries a distance-rate table according to the distance, determines a rate corresponding to the distance in the distance-rate table, and determines the rate as a third rate.

It is to be appreciated that the third rate can be a rate that reduces attenuation during data transmission when the terminal device 101 is at the aforementioned distance from the access device 102.

S2034, the terminal apparatus 101 determines a fourth rate according to the number of apparatuses.

It is to be understood that, when the number of devices is large, in order to avoid that the sum of the rates of data transmission of a plurality of terminals controlled by the control device 105 at the same time exceeds the bandwidth of the control device 105, where the bandwidth may refer to the data amount of data that can be received by the control device 105 in a unit time. The transmission rate of the terminal device 101 should therefore vary as the number of terminals to which its corresponding control device 105 is connected varies. For example, when the number of devices is small, the terminal device 101 may set a larger sending rate in order to improve the efficiency of data transmission; when the number of devices is large, the terminal device may set a smaller transmission rate to ensure the success rate of data transmission.

Generally, the device number-rate correspondence can be obtained through multiple experiments.

In some embodiments, the correspondence between the number of devices and the rate may be presented in the form of a table, where table 4 is a device number-rate table, which presents the correspondence between the number of devices and the rate. The device number-rate table includes a device number column and a rate column. The device number sequence records at least one device number, and the rate sequence records the rate corresponding to each device number.

TABLE 4

Number of devices	Rate of speed
		N1	V41
N2	V42
		N3	V43
…	…

As can be seen from table 4, the rate corresponding to the number N1 of devices is V41; the rate corresponding to the equipment number N2 is V42; the rate corresponding to the number N3 of devices is V43.

It should be noted that table 4 only shows a storage form of the correspondence between the device number and the rate in the storage device in a table form, and is not limited to the storage form of the correspondence between the device number and the rate in the storage device.

In some embodiments, terminal device 101 may obtain the fourth rate for the current device count according to the device count-rate table. The terminal device 101 may obtain the device number-rate table from the control center through the network, or may be imported into the terminal device 101 by an operator through another mobile device (e.g., a usb flash drive).

Specifically, the terminal device 101 obtains the number of devices, queries the device number-rate table according to the number of devices, determines a rate corresponding to the number of devices in the device number-rate table, and determines the rate as a fourth rate.

It is understood that the fourth rate may be a rate that can improve the operating efficiency of the terminal device 101 when the terminal device 101 is in the above-mentioned number of devices.

S2035, the terminal apparatus 101 determines a reference rate according to the first rate, the second rate, the third rate, and the fourth rate.

The reference rate is a rate at which the terminal device 101 transmits the service data, which is determined according to the influence of the environment.

In some embodiments, the reference rate satisfies equation (1).

aV1+bV2+cV3+dV4＝V _b (1)

Wherein, a is the weighted value of the first rate, b is the weighted value of the second rate, c is the weighted value of the third rate, d is the weighted value of the fourth rate, V1 is the first rate, V2 is the second rate, V3 is the third rate, V4 is the fourth rate, V _b Is the reference rate. a. The sum of b, c and d can be 1, and the size of each weight value can be configured according to the actual situation. For example, a, b, c and d all take on values of 0.25. If the influence of a certain parameter of the environmental parameters on the reference rate is relatively large, the weight value of the rate corresponding to the parameter can be correspondingly increased.

For example, if the distance has a large influence on the working efficiency of the terminal device 101, the weight value of the third rate may be increased accordingly. For another example, if the influence of the number of devices on the operation efficiency of the terminal device 101 is large, the weight value of the fourth rate may be increased.

S204, the terminal device 101 determines the offset rate according to the type of the first service.

The offset rate is the rate of sending the service data determined by the terminal device according to the type of the service.

The service type is the type of the polling task, and comprises a real-time video type, a text data type, a video type, an operation execution type, a mobile type and the like.

The real-time video service is used to transmit the video pictures of the inspection scene acquired by the terminal device 101 to the control device 105 in real time.

The text data service is used to transmit the value read by the terminal device 101 from the current meter back to the control device 105, for example, to read the data on the electricity meter at the inspection site, and transmit the data to the control device 105 in the form of text.

The video service is used for transmitting back the audio and video recorded by the terminal device 101 in the inspection site to the control device 105.

The operation execution type service is used to instruct the terminal device 101 to perform actions such as pulling a switch, clicking a button, picking up an article, and the like.

The mobile service is used to instruct the terminal device 101 to move forward, backward, turn, and the like.

The type of service may be any of the types described above.

In some embodiments, the terminal device 101 may determine the offset rate corresponding to each service type according to the requirements of different types of services on the delay and the error rate.

For example, the requirements of the real-time video service on the time delay and the error rate are the highest in the above several service types, so that a larger offset rate can be set for the real-time video service according to data of multiple tests. For another example, the video-recording service has a low requirement on the delay but a high requirement on the error rate, so that an offset rate smaller than the offset rate of the real-time video return service can be set for the video-recording service.

In other embodiments, the terminal device 101 may determine the offset rate of each service type according to the priority corresponding to the service type.

Firstly, a service priority table is constructed according to the requirements of different service types on time delay and error rate, and the higher the requirements on time delay and error rate, the higher the priority of the service. The service priority table is shown in table 5 below:

TABLE 5

Type of service	Priority level	Offset rate
			Real-time video classes	1	V5
Text data class	2	V6
			Class of operation execution	3	V7
Moving class	4	-V8
			Video return class	5	-V9
…	…	…

Wherein priority 1 is the highest priority among the 5 priorities listed in the priority table, and priority 5 is the lowest priority among the 5 priorities listed in the priority table. Each priority has a corresponding offset rate value, the offset rates corresponding to the first three priorities in table 5 are positive numbers, and the offset rates corresponding to the last two priorities are negative numbers. Table 5 is an exemplary listing of possible traffic types and possible priorities. In practice, the traffic type is not limited to the one shown in table 5, and the correspondence relationship between the traffic type and the priority may be different from table 5, and the offset rate corresponding to each priority may also be different from table 5.

The offset rate corresponding to each priority can be set according to actual conditions.

S205, the terminal device 101 adjusts the reference rate according to the offset rate, and determines a first target rate.

The offset rate may be positive or negative.

In some embodiments, the sum of the reference rate and the offset rate may be determined as a target rate for transmitting traffic data.

For example, if the offset rate corresponding to the traffic type is a positive number, the target rate when the traffic data is transmitted is greater than the reference rate. For example, if the reference rate is 4Mbps and the offset rate is 1Mbps, the target rate is 5Mbps. For another example, if the reference rate is 4Mbps and the offset rate is-1 Mbps, the first target rate is 3Mbps.

In other embodiments, the difference between the reference rate and the offset rate may be determined as a target rate for transmitting traffic data. For example, if the reference rate is 4Mbps and the offset rate is 1Mbps, the first target rate is 3Mbps. For another example, if the reference rate is 4Mbps and the offset rate is-1 Mbps, the first target rate is 5Mbps.

In other embodiments, the sum of the absolute values of the reference rate and the offset rate may be determined as the target rate for transmitting traffic data. For example, if the reference rate is 4Mbps and the offset rate is-1 Mbps, the target rate is 5Mbps. For example, if the reference rate is 4Mbps and the offset rate is 1Mbps, the first target rate is 5Mbps. For another example, if the reference rate is 4Mbps and the offset rate is-2 Mbps, the first target rate is 6Mbps.

In other embodiments, the difference between the absolute values of the reference rate and the offset rate may be determined as the target rate for transmitting traffic data. For example, if the reference rate is 4Mbps and the offset rate is 1Mbps, the first target rate is 3Mbps. For another example, if the reference rate is 4Mbps and the offset rate is-2 Mbps, the first target rate is 2Mbps.

S206, the terminal device 101 sends the first service information to the access device 102 according to the first target rate.

The first service information includes data of the first service and a first target rate. The first service information may further include address information of the control device 105, which may be a Media Access Control (MAC) address of the control device 105.

In some embodiments, the network quality between the terminal device 101 and the access device 102 may be poor due to the environment in which the terminal device 101 is located, and a relay device may be provided between the terminal device 101 and the access device 102. The relay device is configured to forward the control information to the terminal device 101 and forward the service information sent by the terminal device 101 to the access device 102. Wherein the relay device forwards the traffic information and the control information at the target rate.

S207, the access device 102 receives the first service information from the terminal device 101.

S208, the access device 102 forwards the first service information to the access device 104.

In the embodiment of the present invention, the access device 102 first sends the first service information to the 5G network 103, and the 5G network 103 forwards the first service information to the access device 104 connected to the control device 105 according to the address of the control device 105 described in the first service information.

S209, the access device 104 receives the first service information from the access device 102.

After receiving the first service information, the access device 104 parses the first service information, obtains the first service data and the first target rate included in the first service information, and executes S210.

S210, the access device 104 sends data of the first service to the control device 105 at the first target rate.

The data of the first service in the first service information is needed by the control device 105, and the first target rate in the first service information is only used to instruct the access device 104 to transmit the data of the first service to the control device 105 at the first target rate, so that the access device 104 may transmit only the data of the first service in the first service information to the control device 105.

S211, the control device 105 receives the data of the first service sent by the access device 104.

Since the access device 104 transmits the data of the first service to the control device 105 at the first target rate, instead of using a fixed rate, the energy consumption of the control device 105 can be effectively saved. For example, if data of a certain service is transmitted at a lower rate, the transmission requirement of the service can be satisfied, and if the data of the service is transmitted to the control device 105 at a higher fixed rate, the control device 105 needs to receive the data of the service at a higher receiving rate, and the higher receiving rate increases the energy consumption of the control device 105.

Since some types of services have particularly high delay requirements, such as real-time video backhaul type services, it is necessary to transmit data of the type of services preferentially. In order to ensure that data of a service with a high requirement on delay can be successfully transmitted, before determining the environment parameter where the terminal device 101 is located, as shown in fig. 4, the method may further include the following steps:

s401, the terminal device 101 determines the priority of the first service according to the type of the first service.

In some embodiments, the priority of the first service may be determined according to table 5 above. For example, if the type of the first service is the operation execution class, the priority of the operation execution class may be determined to be 5 according to the correspondence between the service types and the priorities shown in table 5.

S402, the terminal device 101 determines whether the priority of the first service is the first priority.

The first priority is the highest priority among preset N priorities, and N is an integer greater than or equal to 2. Taking Table 5 as an example, N is 5. The first priority is priority 1 in table 5.

If the priority of the first service is the first priority, S403-S408 are performed.

If the priority of the first service is not the first priority, S202-S211 are performed.

S403, the terminal device 101 sends the first service information to the access device 102 at the fifth rate.

The fifth rate is the maximum transmission rate that can be achieved by the terminal apparatus 101.

For example, assuming that the service type is a real-time video backhaul type, the type has a high requirement on latency and error rate, and therefore, as shown in table 5, the service type is ranked in the first priority in the priority table, and in order to ensure successful completion of the service type, the terminal device 101 may send data of the service type at the maximum sending rate that the terminal device 101 can achieve.

S404, the access device 102 receives the first service information from the terminal device 101.

S405, the access device 102 forwards the first service information to the access device 104.

S406, the access device 104 receives the first service information from the access device 102.

S407, the access device 104 sends the data of the first service to the control device 105 at the fifth rate.

S408, the control device 105 receives the data of the first service sent by the access device 104.

The processes of S403 to S408 are similar to those of S206 to S211, and the specific implementation method of each step in S403 to S408 can refer to S206 to S211, which are not repeated herein.

In some embodiments, to ensure that the service data of the service with high priority can be transmitted preferentially, as shown in fig. 5, before step S206, the method further includes:

s501, the terminal device 101 determines whether the priority of the first service is the second priority.

The second priority is the highest priority among the M priorities, M is an integer greater than zero, and M is less than N. M is the number of priorities included in the queue to be sent in the terminal device 101, where the queue to be sent is a service data queue waiting to be sent. For example, assuming that there are data of a traffic type with a priority of 2, data of a traffic type with a priority of 3, and data of a traffic type with a priority of 5 in the queue to be sent, the second priority is the highest priority among the three priorities, i.e., priority 2.

If the priority of the first service is the second priority, executing S206-S211;

if the priority of the first service is not the second priority, executing S502-S507.

S502, the terminal device 101 sends the second service information to the access device 102 at the second target rate.

The second target rate is a rate for sending the second service information determined by the terminal device 101, wherein the method for determining the second target rate may refer to S202 to S205, which is not described herein again.

The second service information includes data of a second service and a second target rate, the priority of the second service is a second priority, and the second service is a service different from the first service.

S503, the access device 102 receives the second service information from the terminal device 101.

S504, the access device 102 forwards the second service information to the access device 104.

S505, the access device 104 receives the second service information from the access device 102.

S506, the access device 104 sends the data of the second service to the control device 105 at the second target rate.

S507, the control device 105 receives the data of the second service sent by the access device 104.

The above-mentioned processes of S502-S507 are similar to S206-S211, and the specific execution method of each step in S502-S507 can refer to S206-S211, which is not repeated.

Fig. 6 is a method for the control device 105 to send control information to the terminal device 101, and the terminal device 101 sends service information generated in response to the control information to the control device 105 according to an embodiment of the present invention. As shown in fig. 6, the method includes the following steps.

S601, the control device 105 obtains parameters of an environment where the terminal device is located.

The environmental parameters include temperature, humidity, distance, and equipment count. For a detailed explanation of the parameter acquisition method and the temperature, humidity, distance and equipment number, reference may be made to the above S202, which is not described herein again.

It should be noted that the control device 105 may send a call instruction to the terminal device 101, where the call instruction is used to instruct the terminal device 101 to feed back parameters of the environment where the terminal device 101 is located to the control device 105. The present invention does not limit the sending rate and the receiving rate of the call instruction.

After the terminal apparatus 101 transmits the parameters of the environment where it is located to the control apparatus 105, the control apparatus 105 receives the parameters.

S602, the control device 105 determines a reference rate according to the parameter.

Specifically, the control device 105 determines a first rate based on the temperature, a second rate based on the humidity, a third rate based on the distance, a fourth rate based on the number of devices, and then a reference rate based on the first rate, the second rate, the third rate, and the fourth rate. For a specific determination method, reference may be made to the above S2031 to S2035, which are not described herein again.

S603, the control device 105 determines the offset rate according to the type of the first service.

In some embodiments, the offset rates corresponding to different service types may be determined according to table 5, and the specific determination method may refer to S204 described above, which is not described herein again.

S604, the control device 105 determines a first target rate according to the offset rate adjustment reference rate.

The offset rate may be positive or negative. For a specific method for determining the first target rate, reference may be made to the above step S205, which is not described herein again.

S605, the control device 105 sends the first service information to the access device 104 according to the first target rate.

The first control information is information generated by the control device 105 and includes an instruction of the first service and the first target rate. The first control information further includes address information of the terminal apparatus 101, which may be a Media Access Control (MAC) address of the terminal apparatus 101.

In some embodiments, the network quality between the control device 105 and the access device 104 may be poor due to the environment in which the control device 105 is located, and a relay device may be provided between the control device 105 and the access device 104. The relay device is configured to forward the traffic information to the control device 105 and forward the control information sent by the control device 105 to the access device 104. Wherein the relay device forwards the traffic information and the control information at the target rate.

S606, the access device 104 receives the first control information from the control device 105.

S607, the access device 104 forwards the first control information to the access device 102.

In the embodiment of the present invention, the access device 104 first sends the first control information to the 5G network 103, and the 5G network 103 forwards the first control information to the access device 102 connected to the terminal device 101 according to the address of the terminal device 101 described in the first control information.

S608, the access device 102 receives the first control information from the access device 104.

After receiving the first control information, the access device 102 analyzes the first control information, and obtains a first service instruction and a first target rate included in the first control information.

S609, the access device 102 sends the instruction of the first service to the terminal device 101 at the first target rate.

For the terminal device 101, the instruction of the first service in the first control information is needed, and the first target rate in the first control information is only used to instruct the access device 102 to send the instruction of the first service to the terminal device 101 at the first target rate, so that the access device 102 only sends the instruction of the first service in the first control information to the terminal device 101.

S610, the terminal device 101 receives the instruction of the first service sent from the access device 102.

Since some types of traffic have particularly high latency requirements, such as real-time video backhaul type traffic, there is a need to transmit the instructions of this type of traffic preferentially. In order to ensure that the instruction of the service with high requirement on the delay can be successfully transmitted, before determining the environmental parameter of the terminal device 101, as shown in fig. 7, the method further includes the following steps:

s701, the control device 105 determines the priority of the first service according to the type of the first service.

In some embodiments, the priority of the first service may be determined according to the above table 5, for example, if the type of the first service is the operation execution class, the priority corresponding to the service type is queried in table 5 according to the first service type.

S702, the control device 105 determines whether the priority of the first service is the first priority.

If the priority of the first service is the first priority, S703-S708 are performed.

If the priority of the first service is not the first priority, S601-S610 are performed.

S703, the control device 105 sends the first control information to the access device 104 at the sixth rate.

Where the sixth rate is the maximum transmission rate that can be achieved by the control device 105.

For example, assuming that the service type is a real-time video backhaul type, the type has a high requirement on latency and error rate, and therefore, as shown in table 5, the service type is ranked in the first priority of the priority table, and in order to ensure successful completion of the service type, the control device 105 may send the instruction of the service type at the maximum sending rate that the control device 105 can reach.

S704, the access device 104 receives the first control information from the control device 105.

S705, the access device 104 forwards the first control information to the access device 102.

S706, the access device 102 receives the first control information from the access device 104.

S707, the access device 102 sends the instruction of the first service to the terminal device 101 at the sixth rate.

S708, the terminal device 101 receives the instruction of the first service sent from the access device 102.

The above-described processes of S703 to S707 are similar to S604 to S610, and reference may be made to S604 to S610 for a specific execution method of each step in S703 to S707.

In some embodiments, to ensure that the service data of the service with high priority can be transmitted preferentially, as shown in fig. 8, before step S605, the method further includes:

s801, the control device 105 determines whether the priority of the first service is the second priority.

The second priority is the highest priority among the M priorities, M is an integer greater than zero, and M is less than N. M is the number of priorities included in the queue to be sent in the control device 105, where the queue to be sent is a queue of service instructions waiting to be sent. For example, assuming that there are a traffic type with a priority of 2, a traffic type with a priority of 3, and a traffic type with a priority of 5 in the queue to be sent, the second priority is the highest priority among the three priorities, i.e., priority 2.

If the priority of the first service is the second priority, executing S605-S610;

if the priority of the first service is not the second priority, S802-S807 are performed.

S802, the control device 105 sends second control information to the access device 104 according to the second target rate.

The second control information includes an instruction of a second service and a second target rate, the priority of the second service is a second priority, and the second service is a service different from the first service.

S803, the access device 104 receives the first control information from the control device 105.

S804, the access device 104 forwards the second control information to the access device 102.

S805, the access device 102 receives the second control information from the access device 104.

S806, the access device 102 sends the instruction of the second service to the control device 105 at the second target rate.

S807, the terminal device 101 receives the instruction of the second service sent from the access device 102.

The above-described processes of S802-S807 are similar to those of S605-S610, and specific execution methods of each step in S802-S807 can refer to S605-S610.

In other embodiments, the target rate at which the terminal device 101 transmits the service information may be different from the target rate at which the control device 105 transmits the instructions for the first service due to a change in the environment in which the terminal device 101 is located. For example, after the control device 105 determines the target rate according to the parameter of the environment of the terminal device 101 and the type of the first service, the control device 105 sends the instruction of the first service to the terminal device 101 at the target rate. After generating the data of the first service according to the instruction of the first service, the terminal device 101 determines the target rate according to the parameters of the environment where the terminal device is located and the type of the first service. If the parameters of the environment in which the terminal device 101 is located at this time are changed, and if the temperature is reduced, the parameters of the environment in which the terminal device 101 is located at this time are different from the parameters of the environment in which the terminal device 101 is located when the control device 105 determines the target rate. Therefore, the target rate of the terminal apparatus 101 when transmitting the data of the first service to the control apparatus 105 is different from the target rate of the instruction to control the control apparatus 105 to transmit the first service.

In other embodiments, as shown in fig. 9, when the control device 105 is a handheld terminal located in the inspection site, because the terminal device 101 is located closer to the control device 105, the terminal device 101 and the control device 105 may be located in a cell covered by the same base station, and in this case, the access device 102 and the access device 104 may be the same access device, such as the access device 106.

In the environment shown in fig. 9, the control device 105 sends control information to the access device 106, where the control information includes an instruction of a service, a target rate, and an address of the terminal device 101, the access device 106 sends the control information to the 5G network 103, the 5G network 103 forwards the control information to the access device 106 according to the address of the terminal device 101 described in the control information, and the access device 106 parses the control information and sends the instruction of the service to the terminal device 101 according to the target rate described in the control information.

The terminal device 101 sends the service information to the access device 106, wherein the service information includes service data, a target rate and an address of the control device 105, the access device 106 sends the service information to the 5G network 103, the 5G network 103 forwards the service information to the access device 106 according to the address of the control device 105 recorded in the service information, the access device 106 analyzes the service information, and the service data is sent to the control device 105 according to the target rate recorded in the service information.
