Technical field

Background technique

LoRaWAN is a set of protocol specifications developed for the LoRa long-distance communication network based on the LoRa (Long Range Radio) alliance.

The LoRaWAN network architecture is mainly composed of LoRa terminals, gateways and servers. After the LoRa terminals are connected to the network, they can exchange data with the server through the gateway. Among them, the process of reporting data by the LoRa terminal to the server through the gateway is the upstream process. The server The process of issuing commands through the gateway to the LoRa terminal is called the downlink process. When the LoRa terminal receives the downlink command from the server, it needs to respond and feed back to the server to respond to the command. In the LoRaWAN protocol specification, the LoRa terminal has two response modes: immediate response mode and business report mode. The immediate response mode means that the terminal responds immediately after receiving the downlink command and feeds back the response command to the server. The service reporting mode refers to the response command to the downlink command that needs to be carried when the terminal reports the next service. The terminal can choose any one Response mode responds to downstream commands.

In order to ensure reliability, the server will use a timeout mechanism to set the command timeout time. If the response time of the downlink command exceeds the command timeout time, it can be considered that the execution of the downlink command fails, so that the downlink command can be retransmitted. Since the terminal can report services periodically or non-periodically, in order to adapt to the terminal with a longer reporting period, the command timeout time is usually set to be larger, but the command timeout time is larger. For downlink instructions that fail to execute, the Failure to retransmit in time will affect the efficiency of downlink instruction execution.

detailed description

In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application.

Some processes described in the specification and claims of this application and the above drawings include multiple operations in a specific order, but it should be clearly understood that these operations may not be in the order in which they appear in this document Execution or parallel execution. The sequence numbers of operations such as 101 and 102 are only used to distinguish different operations. The sequence number itself does not represent any execution sequence. In addition, these processes may include more or fewer operations, and these operations may be performed sequentially or in parallel. It should be noted that the descriptions of "first", "second", etc. in this article are used to distinguish different messages, devices, modules, etc., and do not represent a sequence, nor limit "first" and "second". Are different types.

The technical solutions of the embodiments of the present application are mainly applied to communication scenarios based on the LoRaWAN network system. LoRaWAN technology is widely used in industrial, scientific and medical fields to achieve wide area communication.

The LoRaWAN network system is mainly composed of LoRa terminals (referred to as terminals in the corresponding explanation below), a gateway (Gateway), and a server. Of course, it may also include a user terminal. , For users to view, etc.

It can be known from the description in the background art that the data interaction between the terminal and the server is divided into uplink and downlink. For convenience of description, in this embodiment of the present application, the content sent by the server to the terminal may be collectively referred to as a downlink command, and the content reported by the terminal to the server Collectively referred to as uplink data. In the LoRaWAN protocol specification, the terminal needs to respond to the downlink command and feed back a response command, and the response command is also reported to the server as an uplink data.

Among them, the server may include NS (Network server, core network server), AS (application server, application server), CS (Custom server, user server) and so on. The terminal is a remote communication terminal, and in different application scenarios, it may be, for example, a remote sensor for collecting business data or a collection device such as an electric energy/electric meter. NS is a server that communicates directly with the gateway. Therefore, the downlink command is transmitted from the NS to the terminal through the gateway, and the downlink command may be a generation command of NS or AS. In different application scenarios, the downlink command may be different. For example, the downlink command may be It is the start instruction for data collection, to start the business data collection with the control terminal.

The terminal can report uplink data periodically or non-periodically, for example, report the collected business data to the server.

Among them, the terminal has three working modes: A, B and C.

Working mode A means that the terminal sends first, and a receiving window is opened for a period of time after sending. The terminal can only receive after sending. That is to say, there is no limit on the uplink, and the downlink command can only be received by the terminal when uplink data is sent.

Working mode B means that the terminal and the server agree on the opening time of the receiving window, and then only agree on the time to receive the downlink command.

Working mode C means that the terminal opens the receiving window at any time other than sending, and can receive downlink commands at any time.

Among them, the terminal response mode to the downlink command includes: immediate response mode and business report mode.

The immediate response mode means that the terminal responds immediately after receiving the downlink command and feeds back a response command to the server;

The service reporting mode means that the response instruction to the downlink instruction is carried in the uplink data reported by the terminal for the next service.

In the embodiment of the present application, the downlink command response time refers to the elapsed time from sending the downlink command to receiving the response command. The command timeout time is set based on the response time of the downlink command, and since the server cannot determine the reporting period of the terminal, in order to adapt to the terminal with a longer reporting period, in the prior art, the command timeout time is usually set to be large. However, for the terminal in the immediate response mode or the short reporting period, if the downlink command is lost during transmission, but the command timeout time has not yet been reached, the command cannot be retransmitted, which will affect the efficiency of downlink command execution. Therefore, the instruction timeout time in the prior art is not reasonable and accurate enough.

The inventor found in the research that the terminal is in the immediate response mode, and the downlink command response time is relatively short, which is usually the network delay time, and the response time of different downlink commands is relatively close, and the distribution is relatively concentrated; and if the terminal is in the service reporting mode 1. Periodic reporting and working in working mode A, the response time of downlink commands is relatively long, and the response time of different downlink commands is close to the reporting cycle, and the distribution is relatively concentrated; and if the terminal is in the business reporting mode, periodic reporting, and work In working mode B or working mode C, the downlink command response time is relatively long and the response time of different downlink commands differs greatly. The distribution is discrete and the longest downlink command response time is close to the reporting period; if the terminal is in the business reporting mode and is not periodic When reporting, the response time of downlink commands is relatively long and the response time of different downlink commands varies greatly, and the distribution is discrete. That is, the terminal is in any working state composed of any response mode, any working mode, and any reporting mode, and the response time of the downlink command has its own characteristics. For the convenience of clear description, the following table 1 lists a terminal in different working states The distribution of response time of downlink commands under

Table 1

Combining the analysis results in Table 1, the inventor found that the response time of the downlink command is related to the terminal's response mode, the terminal's working mode, and the terminal's reporting mode (periodic or aperiodic), and is different in different response modes, different working modes, and different In the reporting mode, the distribution of the response time of the downlink command is different. Therefore, in order to set a reasonable and accurate command timeout time, the response mode, working mode and reporting mode of the terminal can be considered comprehensively, and an adaptive command timeout time can be set for different terminals, so that the server can respond to the command timeout time of different terminals. The terminal's downlink command response process is monitored, and command execution efficiency can be improved on the premise of ensuring command reliability.

Therefore, after further research, the inventor proposes the technical solutions of the embodiments of the present application, comprehensively considering the response mode, working mode and/or reporting mode of the terminal, and setting a suitable and accurate command timeout time for the terminal. In an embodiment of the application, the response time of the terminal for multiple downlink commands is obtained; the first data distribution characteristics of the multiple downlink command response times are determined; and according to the multiple downlink command response times and the first data distribution characteristics, Set the command timeout time of the terminal, that is, analyze the historical downlink command response time, determine the first data distribution characteristics of multiple downlink command response times, combine the first data distribution characteristics, and according to the historical multiple downlink commands Response time, that is, the instruction timeout time suitable for the terminal can be accurately obtained, the accuracy of the instruction timeout time is ensured, and personalized settings for different terminals are realized.

The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the protection scope of the present application.

FIG. 1 is a flowchart of an embodiment of an information determination method provided by an embodiment of the present application. The method may include the following steps:

101: Obtain the response time of the terminal for multiple downlink commands.

Alternatively, it may be to obtain the response time of the most recent downlink commands of the terminal.

The terminal may refer to the LoRa terminal in the LoRaWAN network system, and the downlink command is issued to the LoRa terminal by the server in the LoRaWAN network system. The server may specifically refer to the NS, which is transferred to the LoRa terminal through the gateway.

In order to ensure the timeliness of data, the response time of multiple downlink commands recently issued to the terminal can be obtained to participate in the determination of the command timeout time.

As an optional manner, the response time of the acquiring terminal for multiple downlink commands may include:

Obtain the response time of the terminal for multiple downlink commands within the first time period from the current time.

For example, in practical applications, the first duration may be 10 days, that is, the response time of the downlink command issued within the last 10 days is selected.

As another optional manner, the response time of the acquiring terminal for multiple downlink commands may include:

Obtain the response time of the terminal for the first number of downlink commands issued recently.

The first number may be, for example, 100, that is, select the response time of the last 100 downlink commands.

Wherein, the preset duration and the preset number can be actually set in combination with the requirements on the timeliness and accuracy of the data, and this application does not specifically limit this.

102: Determine a first data distribution characteristic of the response time of the multiple downlink commands.

103: Set the command timeout time of the terminal according to the response time of the multiple downlink commands and the first data distribution characteristic.

The instruction timeout time is used by the server to determine whether the execution of the downlink instruction issued to the terminal has failed.

The first data distribution feature can reflect the distribution of the response time of the multiple downlink commands, and can indicate the working state of the terminal. Therefore, based on the first data distribution feature, based on the response time of the multiple downlink commands, it can be predicted Instruction timeout time. The first data distribution feature can be expressed in various ways. In combination with how the first data distribution feature specifically measures the working state of the terminal and how to set the command timeout period, it will be described in detail in the following embodiments.

In this embodiment, the corresponding command timeout time can be determined for different terminals, instead of using a uniform timeout time, the purpose of adaptively selecting the command timeout time for the terminal is achieved, and the execution efficiency and downlink of the downlink command in the terminal are ensured The reliability of the instruction, therefore, the instruction timeout time obtained by adopting the technical solution of this embodiment is more accurate.

In a possible implementation manner, the first data distribution feature may be represented by a distribution probability of response times of the multiple downlink commands in different time intervals. Therefore, in some embodiments, the first data distribution characteristic that determines the response time of the multiple downlink commands may include:

Divide the first time range into multiple response time intervals according to the first duration;

Determining the distribution probability of the response time of the multiple downlink commands in the multiple response time intervals;

The setting the command timeout time of the terminal according to the response time of the multiple downlink commands and the first data distribution feature includes:

According to the response time interval that the distribution probability meets the requirements in the first set, set the command timeout time.

The first time range may be determined based on a preset minimum response time and a preset maximum response time. The preset minimum response time may be, for example, 0 s (seconds). Of course, it may also refer to the response time of the multiple downlink commands The minimum time; the preset maximum response time may refer to the maximum time among the response times of the multiple downlink commands, and of course may also refer to a pre-configured time.

The first time duration can evenly divide the first time range into multiple response time intervals, for example, the first time range is 0s to 90s, and the first time duration can be 30s, then three response time intervals are obtained: 0s to 30s, 30s ~60s, 60s~90s.

The first duration can be set in conjunction with the accuracy requirement of the instruction timeout time in practical applications, which is not specifically limited in this application.

The distribution probability of the response time of multiple downlink commands in the multiple response time intervals may be determined according to the ratio of the number of downlink command response times hit by each response time to the total number of response time of multiple downlink commands.

For example, the total number of response times of multiple downlink commands is 100, and the response time of downlink commands in the response time interval of 0s to 30s is 3, then the corresponding distribution probability of the response time interval is 3/100=3%; it is in 30s The response time of the downlink command in the ~60s response time interval is 95, then the corresponding probability of distribution in the response time interval is 95/100=95%; the response time of the downlink command in the 60s~90s response time interval is 2, then the The probability of distribution corresponding to the response time interval is 2/100=2%.

As an optional method, the first concentration requirement may mean that the distribution probability is greater than the first probability threshold. Therefore, optionally, the response time interval that satisfies the requirements in the first set according to the distribution probability, and setting the command timeout time may include:

According to the response time interval where the distribution probability is greater than the first probability threshold, the command timeout time is set.

Alternatively, the maximum boundary time of the response time interval whose distribution probability is greater than the first probability threshold or the corresponding maximum downlink command response time may be used as the command timeout time.

For example, if the distribution probability corresponding to the response time interval of 30s to 60s is greater than the first probability threshold, then 60s may be used as the command timeout time, or the maximum downlink command response time hit by the 30s to 60s response time interval may be used as the command timeout time.

In practical applications, the first probability threshold may be set to 95%, for example.

If the response time interval with a distribution probability greater than the first probability threshold includes multiple times, the instruction timeout time may be set according to the maximum response time interval therein.

Of course, as other achievable methods, the command timeout time may also be set according to the response time interval with the largest distribution probability. The maximum boundary time of the maximum response time interval or the corresponding maximum downlink command response time is used as the command timeout time.

As an optional manner, if the distribution probability of any response time interval does not satisfy the first concentration requirement, the predetermined timeout time may be used as the instruction timeout time.

From the above analysis, it can be seen that the response time distribution of the downlink command corresponding to the terminal mainly includes two types: distributed concentration and distributed dispersion. In the case of data distribution, the response time of the corresponding downlink command of the terminal is close to the difference, and the difference is small. In the discrete case, the response time of the downlink command corresponding to the terminal is quite different.

Therefore, if there is a response time interval in which the distribution probability meets the requirements in the first set, it can be considered that the data distribution of the response time of the multiple downlink commands is concentrated, and the data is concentrated in the response time interval in which the distribution probability meets the requirements in the first set. The response time interval can be used to set the command timeout time; if there is no response time interval whose distribution probability meets the requirements in the first set, the data distribution of the response time of the multiple downlink commands can be considered to be discrete. If the data distribution is discrete, the downlink command response time of the terminal in this working state differs greatly, and there is no regularity. At this time, the predetermined timeout time can be directly used as the command timeout time.

In order to adapt to a terminal with a long reporting period, the predetermined timeout period may be set to be relatively large, such as 24 hours.

As another optional method, since the terminal will report uplink data to the server, when the terminal is in the immediate response mode, the uplink data may refer to service data, or it may refer to a response command to the downlink command; when the terminal is in the service reporting mode , The response instruction will be carried in the service data for reporting, so the uplink data may refer to the service data, and may also include the service data and the response instruction.

There is a time interval between the uplink data reported by the terminal, that is, the uplink data reporting interval. When the terminal is in the service reporting mode and is periodically reported, the uplink data reporting interval also refers to the reporting period.

It can be seen from the above analysis that when the terminal periodically reports and is in working mode A, the downlink command response time is close to the reporting cycle; when the terminal periodically reports and is in working mode B or C, the longest downlink command response time is close to the reporting cycle. Therefore, in some scenarios, the uplink data reporting interval is equal to the downlink command response time. According to this, if the distribution probability of any response time interval does not meet the requirements of the first set, the inventor thinks that the command timeout time can also be predicted in conjunction with the uplink data reporting interval.

Therefore, in some embodiments, the method may further include:

If the distribution probability of any response time interval does not meet the first concentration requirement, acquire multiple uplink data reporting intervals of the terminal;

Optionally, it may be to obtain the latest multiple uplink data reporting intervals of the terminal.

Wherein, if the distribution probability of any response time interval does not meet the first concentration requirement, the reporting interval for acquiring multiple uplink data of the terminal may be that if the distribution probability of any response time interval does not meet the first concentration requirement, obtain The most recent uplink data reporting interval of the terminal that is greater than the preset interval duration.

That is, the upstream data reporting interval is filtered. The upstream data reporting interval that is shorter than the preset interval can be considered to be caused by the terminal retransmission operation. In the LoRaWAN protocol specification, the terminal retransmission interval is usually small, for example, 10s. The uplink data reporting interval generated by the transmission operation is unlikely to be the downlink command response time, so only the uplink data reporting interval greater than the preset interval duration can be selected to participate in determining the command timeout time.

Wherein, the multiple uplink data reporting intervals may be multiple uplink data reporting intervals within a second preset duration from the current time, or the second number of uplink data reporting intervals generated recently.

Optionally, the second data distribution feature may be represented by a distribution probability of the multiple uplink data reporting intervals in different time intervals. Therefore, in some embodiments, the second data distribution characteristic that determines the plurality of uplink data reporting intervals may include:

Divide the second time range into multiple reporting time intervals according to the second duration;

Determine the distribution probability of the response time of the multiple downlink commands in the multiple reporting time intervals;

The command timeout period of the terminal is set according to the plurality of uplink data reporting intervals and the second data distribution characteristics.

Set the instruction timeout time according to the reporting time interval where the distribution probability meets the requirements in the second set.

The second duration example may be 200s, and the second time range may be evenly divided into multiple reporting time intervals.

The second time range may be determined based on a preset minimum interval time and a preset maximum interval time. The preset minimum interval time may be, for example, 0 s, and of course, may also refer to the minimum interval time among the multiple uplink data reporting intervals; The preset maximum interval time may refer to the maximum interval time among the multiple uplink data reporting intervals, and of course, may also refer to a pre-configured time.

As an optional method, the second concentration requirement may refer to a distribution probability greater than a second probability threshold. Therefore, optionally, the reporting time interval that meets the requirements in the second set according to the distribution probability, setting the instruction timeout time may include:

The maximum boundary time of the reporting time interval whose distribution probability is greater than the second probability threshold or the corresponding maximum uplink data reporting interval is used as the instruction timeout time.

In practical applications, the second probability threshold may be set to 70%, for example.

If the reporting time interval with a distribution probability greater than the second probability threshold includes multiple times, the instruction timeout time may be set according to the maximum reporting time interval therein.

Of course, as other achievable methods, the instruction timeout time may be set according to the reporting time interval with the largest distribution probability, and the maximum boundary time value of the maximum reporting time interval or the corresponding maximum uplink data reporting interval may be used as the instruction timeout time. .

In addition, in some embodiments, if the distribution probability of any reporting time interval does not meet the second concentration requirement, the predetermined timeout time may be used as the instruction timeout time.

Since the uplink data reporting interval can be used as the downlink command response time, if there is a reporting time interval with a distribution probability that meets the requirements in the second set, the data distribution of the multiple uplink data reporting intervals can be considered to be concentrated, so this report can be used Time interval to set the command timeout time; if there is no reporting time interval with a distribution probability that meets the requirements in the second set, it can be considered that the data distribution of the multiple uplink data reporting intervals is discrete. In this case, the predetermined timeout time can be directly used as the Instruction timeout time.

FIG. 2 shows a flowchart of yet another embodiment of an information determination method provided by an embodiment of the present application. The method may include the following steps:

201: Obtain the response time of the terminal for the latest multiple downlink commands.

202: Divide the first time range according to the first duration to obtain multiple response time intervals.

203: Determine the distribution probability of the response time of the multiple downlink commands in the multiple response time intervals.

204: Determine whether there is a response time interval whose distribution probability meets the requirements in the first set, and if so, perform step 205; if not, perform step 206;

205: Set the command timeout time according to the response time interval where the distribution probability meets the requirements in the first set.

206: Obtain the latest multiple uplink data reporting intervals of the terminal.

207: Divide the second time range according to the second duration to obtain multiple reporting time intervals.

208: Determine the distribution probability of the response time of the multiple downlink commands in the multiple reporting time intervals.

209: Determine whether there is a reporting time interval whose distribution probability meets the requirements in the second set. If yes, perform step 210; if not, perform step 211.

210: Set the instruction timeout time according to the reporting time interval where the distribution probability meets the requirements in the second set.

211: The predetermined timeout time is used as the instruction timeout time.

In addition, as yet another embodiment, the second data distribution feature may also be represented by a second degree of dispersion of multiple uplink data reporting intervals. The second degree of dispersion may refer to, for example, the variance or standard deviation of the reporting interval of multiple uplink data.

Therefore, in some embodiments, determining the second data distribution characteristics of the multiple uplink data reporting intervals may include:

Determine a second degree of dispersion of the reporting interval of the plurality of uplink data;

The combination of the multiple uplink data reporting intervals and the second data distribution characteristics to set the command timeout time of the terminal may include:

Calculating the average interval time of the reporting interval of the multiple uplink data;

Use the second degree of dispersion to perform time compensation on the average interval time to obtain an instruction timeout time.

The second degree of dispersion also indicates the degree of deviation of the reporting interval of multiple upstream data from the average interval time.

Wherein, using the second degree of dispersion to perform time compensation on the average interval time to obtain the instruction timeout time, the product of the second degree of dispersion and the expansion coefficient can be superimposed on the average interval time to obtain the instruction timeout time, the The expansion and contraction coefficient is greater than 1, and can be specifically set according to the actual application situation.

In some embodiments, the average interval time for calculating the plurality of uplink data reporting intervals may be:

If the second dispersion degree does not satisfy the second dispersion condition, calculate the average interval time of the multiple uplink data reporting intervals.

The second degree of dispersion may refer to the variance of a plurality of uplink data reporting intervals, and the second discrete condition may be, for example, that the variance of the multiple uplink data reporting intervals is greater than a second discrete threshold.

If the second discrete degree does not satisfy the second discrete condition, it can be considered that the deviation of the multiple uplink data reporting intervals deviates from the average interval time, and the data distribution of the multiple uplink data reporting intervals is concentrated. In this case, the second discrete Degree and average interval time to calculate the timeout period of obtaining instructions. It may be that the product of the second dispersion degree and the expansion and contraction coefficient is superimposed on the average interval time to obtain the instruction timeout time. The expansion and contraction coefficient is greater than 1, which can be specifically set in conjunction with the actual application situation.

Then the method may further include:

If the second discrete degree meets the second discrete condition, the predetermined timeout time is used as the instruction timeout time.

That is, if the second discrete degree meets the second discrete condition, it can be considered that the multiple uplink data reporting intervals deviate greatly from the average interval time, and the data distribution of the multiple uplink data reporting intervals is discrete. In this case, the predetermined timeout can be directly overtime The time is used as the instruction timeout time.

In addition, in some embodiments, the use of the second degree of dispersion to perform time compensation on the average interval time, and obtaining the instruction timeout time may be:

If the second dispersion degree satisfies the second dispersion condition, the second interval is used to perform time compensation on the average interval time to obtain an instruction timeout time.

The method may further include:

If the second dispersion degree does not satisfy the second dispersion condition, the average interval time is used as the instruction timeout time.

Since the second dispersion degree satisfies the second dispersion condition, it can be considered that the multiple uplink data reporting intervals deviate greatly from the average interval time, and the second dispersion degree can refer to the degree of deviation of the multiple uplink data reporting intervals from the average interval time Therefore, by compensating for this second degree of dispersion on the basis of the average interval time, the degree of deviation between the reporting interval of multiple upstream data and the average interval time can be balanced, and the obtained result can be used as the instruction timeout time.

However, the second dispersion degree does not satisfy the second dispersion condition, it can be considered that the deviation of the multiple uplink data reporting intervals deviates from the average interval time, the data distribution of the multiple uplink data reporting intervals is concentrated, and the second dispersion degree can be ignored, so , You can directly use the average interval time as the instruction timeout time.

Use the first degree of dispersion to perform time compensation on the average response time to obtain an instruction timeout time.

Wherein, the first degree of dispersion may refer to the variance of the response time of the multiple downlink commands. Therefore, the first degree of dispersion may be calculated as follows:

Where σ ² is the variance, indicating the first degree of dispersion, X is the downlink command response time, μ is the average response time, and N is the total number of the downlink quality response times.

Of course, the first degree of dispersion may also refer to the standard deviation and range of response times of multiple downlink commands. The first degree of dispersion represents the degree of deviation of the response time of multiple downlink commands from the average response time.

Wherein, using the first degree of dispersion to compensate the average response time to obtain the command timeout time, the product of the first degree of dispersion and the expansion factor can be superimposed on the average response time to obtain the command timeout time, the The expansion and contraction coefficient is greater than 1, and can be specifically set according to the actual application situation. As described in the following formula:

M=μ+α+σ ² ;

Among them, M represents the instruction timeout time, α is the expansion and contraction coefficient greater than 1.

Wherein, in some embodiments, calculating the average response time of the response time of the multiple downlink commands may include:

If the first discrete degree does not satisfy the first discrete condition, calculate the average response time of the response time of the multiple downlink commands.

Wherein, the first degree of dispersion includes the variance of the response time of the multiple downlink commands;

The first discrete condition may be that the variance of the response time of the multiple downlink commands is greater than the first discrete threshold.

If the first degree of dispersion meets the first discrete condition, it can be considered that the response time of the multiple downlink commands deviates from the average response time relatively small, and the data distribution of the response time of the multiple downlink commands is concentrated. In this case, the first discrete The degree and average response time are used to calculate the timeout period for obtaining the command.

As an optional manner, if the first degree of dispersion meets the first discrete condition, the method may further include:

Take the predetermined timeout time as the instruction timeout time.

That is, if the first discrete degree meets the first discrete condition, it can be considered that the response time of the multiple downlink commands deviates greatly from the average response time, and the data distribution of the multiple uplink data reporting intervals is discrete. In this case, the predetermined timeout can be directly overtime The time is used as the instruction timeout time.

In addition, as yet another optional manner, if the first dispersion degree meets the first dispersion condition, the method may further include:

Obtain multiple uplink data reporting intervals of the terminal;

It can be seen from the above analysis that in some scenarios, the uplink data reporting interval is equal to the downlink command response time. Therefore, when the first discrete degree meets the first discrete condition, the uplink data reporting interval can be combined to predict the command timeout time.

Optionally, if the first dispersion degree satisfies the first dispersion condition, acquiring multiple uplink data reporting intervals of the terminal may be if the first dispersion degree satisfies the first dispersion condition, acquiring the terminal's most recent Multiple uplink data reporting intervals with preset intervals.

As an optional manner, the second data distribution feature may be represented by a second degree of dispersion of multiple uplink data reporting intervals. The second degree of dispersion may refer to, for example, the variance or standard deviation of the reporting interval of multiple uplink data.

Therefore, the second data distribution characteristic that determines the plurality of uplink data reporting intervals may include:

The setting the command timeout period of the terminal according to the plurality of uplink data reporting intervals and the second data distribution characteristics includes:

Then the method may further include:

In addition, in some embodiments, the average interval time for calculating the plurality of uplink data reporting intervals may be:

If the second dispersion degree satisfies the second dispersion condition, calculate the average interval time of the plurality of uplink data reporting intervals.

The method may further include:

As shown in FIG. 3, it is a flowchart of another embodiment of an information determination method provided by an embodiment of the present application. The method may include the following steps:

301: Obtain the response time of the terminal for the latest multiple downlink commands.

302: Determine a first discrete degree of response time of the multiple downlink commands.

303: Determine whether the first degree of dispersion meets the first dispersion condition, if not, perform step 304, and if so, perform step 306.

305: Use the first degree of dispersion to perform time compensation on the average response time to obtain an instruction timeout time.

306: Obtain the latest multiple uplink data reporting intervals of the terminal.

307: Determine a second degree of dispersion of the reporting interval of the multiple uplink data.

308: Determine whether the second dispersion degree meets the second dispersion condition. If not, perform step 309, and if yes, perform step 311.

309: Calculate the average interval time of the multiple uplink data reporting intervals.

310: Use the second degree of dispersion to perform time compensation on the average interval time to obtain an instruction timeout time.

311: The predetermined timeout time is used as the instruction timeout time.

Of course, as another embodiment, when the second dispersion degree meets the second dispersion condition, the second interval can be used to perform time compensation on the average interval time to obtain an instruction timeout time. When the second discrete degree does not satisfy the second discrete condition, the average interval time is directly used as the instruction timeout time.

As yet another embodiment, using the first degree of dispersion to perform time compensation on the average response time, and obtaining an instruction timeout time includes:

If the first dispersion degree meets the first dispersion condition, use the first dispersion degree to perform time compensation on the average response time to obtain an instruction timeout time;

The method also includes:

If the first discrete degree does not satisfy the first discrete condition, the average response time is used as the instruction timeout time.

Since the first degree of dispersion meets the first discrete condition, it can be considered that the data distribution of multiple downlink command response times is discrete and deviates greatly from the average response time, and the first degree of dispersion refers to the response time of multiple downlink commands and the average response The degree of deviation of time, therefore, the first degree of dispersion is compensated on the basis of the average response time, which can balance the degree of deviation between the response time of multiple downlink commands and the average response time, and the result obtained can be used as the command timeout time.

However, the first degree of dispersion does not satisfy the first dispersion condition, it can be considered that the response time of the multiple downlink commands deviates from the average response time less, the data distribution of the response time of the multiple downlink commands is concentrated, and the first degree of dispersion can be ignored, so , You can directly use the average response time as the command timeout time.

As another optional manner, the second data distribution feature may also be represented by a distribution probability of the multiple uplink data reporting intervals in different time intervals. Therefore, in some embodiments, the second data distribution characteristic that determines the plurality of uplink data reporting intervals may include:

It can be seen from the above analysis that when the terminal is in the immediate response mode, the response time of downlink commands is small, and the response time of different downlink commands is close, and the distribution of response time of downlink commands is relatively concentrated. When the terminal is in the service reporting mode, the response time of the downlink command is large, and it is related to the reporting period.

Therefore, in some embodiments, the method may further include:

Determine whether the terminal is in an immediate response mode based on the response time of the multiple downlink commands;

If yes, execute the step of determining the first data distribution characteristics of the response time of the multiple downlink commands;

If not, obtain multiple uplink data reporting intervals of the terminal;

For the method of using multiple uplink data reporting intervals to predict the command timeout time, reference may be made to the foregoing embodiment, and details are not described herein again.

If the terminal is in the periodic reporting mode, the uplink data reporting interval also refers to the reporting period.

Optionally, the determining whether the terminal is in the immediate response mode based on the response time of the multiple downlink commands may include:

Judging whether the response times of the multiple downlink commands are all less than the first time threshold; wherein, if the response times of the multiple downlink commands are less than the first time threshold, it is determined that the terminal is in the immediate response mode.

In addition, from the above analysis, we can see that the response time distribution of the downlink commands corresponding to the terminal mainly includes two types: distributed concentration and distributed dispersion. In the case of centralized data distribution, the response time of the downlink command corresponding to the terminal is close, and the difference is small; In the case of discrete data distribution, the response time of the downlink command corresponding to the terminal varies greatly.

Therefore, as yet another embodiment, the setting the command timeout time of the terminal according to the response time of the multiple downlink commands and the first data distribution feature may include:

If the data distribution set of the response time of the multiple downlink commands is determined based on the first data distribution characteristics, the command timeout time may be set based on the response time of the multiple downlink commands;

If it is determined that the data distribution of the response time of the plurality of downlink commands is discrete based on the first data distribution characteristic, the predetermined timeout time may be used as the instruction timeout time.

Among them, the data distribution concentration indicates that the terminal may be in the immediate response mode, or the periodic service reporting mode and in the working mode A, the terminal is in the corresponding working state in the data distribution set, and the downlink command response time is close, so the historical Multiple downlink command response time to set command timeout time.

The discrete data distribution indicates that the terminal may be in the acyclic service reporting mode, or the periodic reporting mode and in the working mode B/C, the terminal is in the working state corresponding to the discrete data distribution, and the downlink command response time is not regular and the difference If it is large, you can directly select the predetermined timeout time as the instruction timeout time.

Wherein, if the data distribution concentration of the response time of the plurality of downlink commands is determined based on the first data distribution characteristics, based on the response time of the plurality of downlink commands, there may be multiple ways to set the command timeout time:

For example, the average response time of multiple downlink command response times can be used as the command timeout time;

For another example, the first discrete degree of response time of multiple downlink commands may be calculated first, and the average response time may be compensated based on the first discrete degree to obtain the command timeout time. Therefore, in some embodiments, the first data distribution feature may be represented by a first discrete degree of response time of multiple downlink commands, and the first data distribution feature that determines the response time of the multiple downlink commands may include:

If the data distribution set of the response time of the multiple downlink commands is determined based on the first data distribution characteristics, based on the response time of the multiple downlink commands, setting the command timeout time may include:

For the first dispersion degree and the compensation calculation method, etc., reference may be made to the corresponding embodiments above, and details are not described herein again.

For another example, the data set area of multiple downlink command responses may be analyzed, and the command timeout time may be set based on the time category corresponding to the data set area. Therefore, in some embodiments, the first data distribution feature may be represented by the distribution probability of multiple downlink command response times in different time intervals. The first data distribution characteristic that determines the response time of the multiple downlink commands may include:

Then, if the data distribution set of the response time of the multiple downlink commands is determined based on the first data distribution characteristics, based on the response time of the multiple downlink commands, setting the command timeout time may include:

If the data distribution set of the response time of the multiple downlink commands is determined based on the first data distribution characteristics, the first time range is divided according to the first duration to obtain multiple response time intervals;

For the same or similar steps in the above implementation solution, reference may be made to one or more of the above embodiments, which will not be repeated here.

In addition, if the data distribution of the response time of the multiple downlink commands is determined to be discrete based on the first data distribution characteristics, the historical uplink data reporting interval may also be used to predict the command determination time.

Therefore, in some embodiments, according to the response time of the plurality of downlink commands and the first data distribution characteristic, setting the command timeout time of the terminal includes:

If it is determined based on the first data distribution characteristics that the data distribution set of the response time of the multiple downlink commands is set, based on the response time of the multiple downlink commands, an instruction timeout time is set;

If it is determined that the data distribution of the response time of the plurality of downlink commands is discrete based on the first data distribution characteristic, obtain a plurality of uplink data reporting intervals of the terminal;

For a specific method of setting the command timeout time of the terminal by using multiple uplink data reporting intervals, reference may be made to the foregoing corresponding embodiments, and details are not described herein again.

Of course, as another embodiment, in the information determination method shown in FIG. 4, the method may include the following steps:

401: Obtain the response time of the terminal for multiple downlink commands.

Alternatively, it may be the response time of the terminal for the latest multiple downlink commands.

402: Determine a first data distribution characteristic of the response time of the multiple downlink commands.

403: If the data distribution concentration of the response time of the multiple downlink commands is determined based on the first data distribution feature, the command timeout time is set based on the response time of the multiple downlink commands.

Wherein, if the data distribution concentration of the multiple uplink data reporting intervals is determined based on the second data distribution characteristics, an instruction timeout period is set based on the multiple uplink data reporting intervals, for example, multiple uplink data reporting intervals may be set The average interval time is used as the instruction timeout time;

For another example, the second dispersion degree of the reporting interval of multiple uplink data may be calculated first, and the average interval time may be compensated based on the second dispersion degree to obtain the instruction timeout time.

For another example, a plurality of upstream data reporting intervals may be analyzed in the data set area, and the command timeout period may be set based on the time category corresponding to the data set area. Therefore, in some embodiments, if the data distribution set of the multiple uplink data reporting intervals is determined based on the second data distribution characteristics, based on the multiple uplink data reporting intervals, the instruction timeout period may be set include:

Alternatively, the maximum boundary time of the reporting time interval with a distribution probability greater than the second probability threshold or the corresponding maximum uplink data reporting interval may be used as the instruction timeout time.

501: Acquire multiple uplink data reporting intervals of the terminal.

502: Determine a second data distribution characteristic of the multiple uplink data reporting intervals.

503: Set an instruction timeout time of the terminal according to the multiple uplink data reporting intervals and the second data distribution characteristics.

Since the terminal will report the upstream data to the server, when the terminal is in the immediate response mode, the upstream data may refer to the business data, or it may be a pointer to the response command to the downstream command; when the terminal is in the business reporting mode, the response command will be carried in the business data Reporting in, so the uplink data can refer to business data, can also include business data and response instructions.

There is a time interval between the uplink data reported by the terminal, that is, the uplink data reporting interval. When the terminal is in the service reporting mode and periodically reports, the uplink data reporting interval also refers to the reporting period. It can be seen from the above analysis that when the terminal periodically reports and is in working mode A, the downlink command response time is close to the reporting cycle; when the terminal periodically reports and is in working mode B or C, the longest downlink command response time is close to the reporting cycle.

Therefore, in some scenarios, the uplink data reporting interval is equal to the downlink command response time, and in some scenarios, the uplink data reporting interval is equal to the reporting period. Therefore, the uplink data reporting interval can be used to predict the command timeout time. Ensure the accuracy of the instruction timeout time.
