Specific embodiment
The technical solution of the application is further elaborated on reference to the accompanying drawings and examples.
Figure 1A is the framework and network element composition of illustrative LoRaWAN communication network, includes in the LoRaWAN communication network
Terminal 141, terminal 142, terminal 143, gateway 151, gateway 152 and server 160.
It is integrated with LoRaWAN network protocol service and LoRaWAN network management services in server 160, has LoRaWAN
LoRaWAN Message processing function and terminal, the gateway management function of consensus standard defined.
Communication mode between server 160 and gateway 151, gateway 152 is IP(Internet Protocol, internet association
View) broadband connections, such as Ethernet, 4G(the 4th Generation mobile communication technology,
Fourth generation mobile communication technology), WIFI(Wireless Fidelity, the WLAN skill based on IEEE 802.11b standard
Art), VSAT(Very Small Aperture Terminal, miniature earth station) satellite etc..
Communication mode between gateway 151, gateway 152 and corresponding terminal is LoRaWAN wireless communication.Gateway
151, gateway 152 has LoRaWAN message transmission function, and corresponding terminal is to have the sensor end of LoRaWAN communication function
End.In Figure 1A, when terminal 141, terminal 142 and terminal 143 are communicated with gateway 151 or gateway 152, assisted using LoRaWAN
View.
The downlink window opening process of LoRaWAN terminal is introduced by taking terminal 141 as an example below.As shown in Figure 1B, work as terminal
141 under Class mode A, if necessary to send uplink message to server 160, can open a uplink window 110.On
After row message is sent, terminal 141 will close uplink window 110, and in waiting setting after the closing of uplink window 110
The first downlink window 120 is opened after prolonging.Then, terminal 141 will make the first downlink window 120 maintain open state, at one section
The first downlink window 120 is closed after time.
Those skilled in the art will be seen that, terminal 141 can choose through the perhaps gateway 152 or simultaneously of gateway 151
Uplink message is sent to server 160 by gateway 151 and gateway 152.After server 160 receives uplink message, to upper
Row message is handled, and response message is generated.Terminal 141 is sent by gateway 151 or gateway 152 by response message.
When response message reaches terminal 141, if the first downlink window 120 is in the open state, terminal 141 is connect
The response message is received, the second downlink window 130 will not be then turned on.If terminal 141 do not open also the first downlink window 120 or
The second downlink of person window 130 has been switched off, and terminal 141 will be unable to receive the response message.The needs of server 160 re-issue
Response message, terminal 141 can open the first downlink window 120 or the at the time of setting time delay or window opens interval arrival
Two downlink windows 130.During a successful message issues, terminal 141 needs under the first downlink window 120 or the second
The open stage of row window 130 receives the response message that server 160 issues.
In LoRaWAN communication protocol, allow terminal network the stage and network after stage of communication to setting time delay into
Row modification.Under normal conditions, the setting time delay of terminal and window, which open interval, can use agreement default parameters or one
It is different from the fixed value of default parameters.That is, it is generally the case that the setting time delay and window of terminal, which open interval, is
Fixed, it will not change, for example, setting time delay as 1 second, it is 1 second that window, which opens interval also,.
But as shown in Figure 1A, after uplink message is sent server 160 by terminal 141, server 160 is received
The time of response message is not sustained.The time wherein spent may be by gateway 151 or gateway 152 and server
The influence of communication condition between 160, it is also possible to the processing speed of message be influenced by server 160, lead to terminal 141
A kind of irregular dispersity is presented in the response time of the uplink message of sending.If the setting time delay of terminal 141 maintains not
Become, in the response message of a certain number of uplink messages, the event of data loss of significant proportion necessarily occurs.
After terminal 141 has sent uplink message to server 160, if response message cannot be properly received, it will bring
Following problems:
1) terminal 141 judges that itself is in off-network state, frequently attempts suspension reconnection, influences regular traffic；
2) terminal 141 reduces the transmission rate of data automatically, and equipment power dissipation is caused to increase, and the occupancy of radio frequency resource is promoted, whole
Network transmission environmental degradation；
3) server 160 retransmits response message several times, and the equipment power dissipation of terminal 141 is caused to increase, server 160
Data processing load increases.
In order to avoid wasting of resources situation more than appearance, when the embodiment of the present application provides a kind of unlatching of user equipment downlink window
The control method of machine.

The downlink message that business device issues.
Here, after terminal 141 issues uplink message, interval how long can just receive the response report of server 160
Text is determined by gateway time delay.In order to guarantee that terminal 141 can be successfully received response message, response message loss is avoided to make
It at the wasting of resources, needs to be arranged according to gateway time delay the setting time delay of terminal 141, improves terminal 141 and receive response message
Success rate.
As shown in Figure 1B, setting time delay terminates as the transmission uplink message of terminal 141 between the first downlink window 120 of unlatching
Time difference.In general, setting the unit of time delay as the second.
In the embodiment of the present application, the setting time delay of terminal is set according to the network delay of forward gateway, to control end
The unlatching opportunity of downlink window is held, can be fluctuated to avoid network environment or server load variation causes terminal to receive response report
The success rate decline of text, leads to the wasting of resources.
Embodiment two
The embodiment of the present application provides a kind of control method on user equipment downlink window unlatching opportunity, which opens opportunity
Control method include:
S210 determines the mark of the forward gateway to E-Packet between the terminal and server.
S220 obtains the propagation delay time between the forward gateway and the server.
In the embodiment of the present application, the propagation delay time between forward gateway and server is for characterizing the forward gateway and institute
State the speed speed of transmitting message between server.As shown in Figure 1A, propagation delay time is from forward gateway i.e. gateway 151 to service
Transmission duration the sum of of the transmission duration and response message of device 160 from server 160 to gateway 151.
In order to obtain propagation delay time, in some embodiments, S220 the following steps are included:
S221, the transmission duration of at least one message reported according to forward gateway described in the period 1 with second round, really
The propagation delay time of the fixed forward gateway；Wherein, the second round is less than the period 1.
Here, every second round, gateway 151 reports the transmission duration an of message to server 160.Second round is small
In the period 1.For example, the period 1 can be the integral multiple of second round, for example, 10 times.So, server 160 is by basis
Report recently the 10 transmission durations of gateway 151 determine the propagation delay time of gateway 151.By increasing the number of transmission duration,
Random error can be reduced, the accuracy in computation of propagation delay time is improved.
The value of second round can be determining, and it is according to the fluctuation of communication condition determining to be also possible to server 160.Such as
Fruit communication condition maintains to stablize, and the propagation delay time of gateway 151 will remain unchanged as whithin a period of time, and server 160 can increase
The value of second round reduces calculation amount.If communication condition fluctuation is very big, random errors affect result is accurate in order to prevent
Property, server 160 can reduce the value of second round, increase the sample frequency of transmission duration, to exclude the influence of random error,
Improve the accuracy of result.
The transmission duration for the message that gateway 151 is reported to server 160 can be uplink message from forward gateway i.e. gateway
151 arrive the transmission duration of server 160, are also possible to transmission duration of the response message from server 160 to gateway 151, can also
To be the sum of both of the aforesaid transmission duration.
If the transmission duration that gateway 151 reports is transmission duration of the uplink message from gateway 151 to server 160, can
To determine the transmission duration of message by sending common uplink message to server 160.As shown in Figure 1A, gateway 151 to
Server 160 sends uplink message.After server 160 receives uplink message, at the time of record receives the uplink message,
And the time of reception is written in the response message then issued.Gateway 151 receives after response message, so that it may according to this
The transmission duration of message is determined at the time of receiving the moment and send uplink message.
If the transmission duration that gateway 151 reports is transmission duration of the response message from server 160 to gateway 151, net
The transmission duration of message can be determined by receiving the generic downlink message that server 160 is sent by closing 151.As shown in Figure 1A,
Server 160 sends downlink message to gateway 151, and the sending instant of the downlink message is written in downlink message.Gateway 151
After receiving downlink message, so that it may determine message with the sending instant according at the time of itself receiving the downlink message
Transmit duration.
If the transmission duration that gateway 151 reports is uplink message from forward gateway i.e. biography of the gateway 151 to server 160
The sum of the transmission duration of defeated duration and response message from server 160 to gateway 151, gateway 151 can be by sending out to server
Dedicated message is sent to determine the transmission duration of message.As shown in Figure 1A, forward gateway namely gateway 151 are sent to server 160
Dedicated message.After server 160 receives dedicated message, dedicated message can be handed down to gateway 151.In this way, eliminating clothes
Be engaged in influence of the device 160 to the processing delay of dedicated message, gateway 151 can directly according to after issuing dedicated message, to receiving
The time difference of the dedicated message determines the transmission duration of message.
If what gateway 151 reported is the transmission duration of one way, server 160 need to report gateway 151 at least one
Transmission duration of the transmission duration of a message multiplied by 2, as message in a complete message response period；If on gateway 151
Report is that message one carrys out past the sum of a transmission duration between gateway 151 and server 160, then the report that gateway 151 reports
Text transmission duration is the transmission duration of message in a complete message response period.
Transmission duration based at least one message, server 160 can be by averaging to obtain the transmission of gateway 151
Time delay can also intend the regularity of distribution for transmitting duration and existing probability-distribution function (such as normal distyribution function)
It closes, obtains the desired value of propagation delay time.Here, transmission duration is the transmission duration of message in a complete message response period.
In order to determine propagation delay time based on the transmission duration of at least one message, in some embodiments, S221 includes
Following steps:
S221a, according to the transmission duration distribution arrangement serial number that sequence from small to large is at least one message.
S221b sorts according to transmission duration of the arrangement serial number at least one message, when obtaining message transmissions
Long sequence.
The total number of the arrangement serial number is rounded multiplied by setting ratio, and by product, obtains selected serial number by S221c.
S221d, by the corresponding propagation delay time transmitted duration and be determined as the forward gateway of the selected serial number.
Here, according to the transmission duration distribution arrangement serial number that sequence from small to large is at least one message.If transmission
The number of duration is 15, then the corresponding arrangement serial number 1 of the smallest transmission duration of numerical value, the maximum transmission duration of numerical value is corresponding
Arrangement serial number 15.When transmitting duration according to the sequence arrangement of serial number from small to large is arranged to get message transmissions are arrived for 15
Long sequence.
Typically, caused by the maximum value in message transmissions duration sequence is likely due to enchancement factor, reference price
It is worth lower.Therefore, in the embodiment of the present application, it is provided with a setting ratio, this setting ratio is less than 1, to exclude maximum
It is worth the influence of the enchancement factor represented.
In some embodiments, this setting ratio is also greater than 0.5, to adapt to propagation delay time caused by communication condition deterioration
Increase.For example, setting ratio can be 0.8.In this way, the total number 15 for arranging serial number is obtained multiplied by setting ratio 0.8
Product is 12, and selected serial number is 12.The corresponding transmission duration of serial number 12 is determined as propagation delay time.
In other embodiments, setting ratio can also be 0.7.In this way, the total number 15 of serial number will be arranged multiplied by setting
Ratio 0.7, obtained product are 10.5, need to be rounded product.In the embodiment of the present application, it can round up, obtain to product
To 11；Product can also be rounded downwards, obtain 10.
S230 obtains the server to the processing delay of uplink message.
Server is used to characterize the speed speed of the server process uplink message to the processing delay of uplink message.Such as
Shown in Figure 1A, server 160 needs to handle the uplink message from multiple terminals, and is managed to multiple terminals and gateway.
In this way, server 160 possibly can not receive after the uplink message of terminal 141 at the first time just to the uplink message at
Reason.On the other hand, server 160 needs while handling a large amount of uplink messages, under the operational capability that may cause server 160
Drop, to influence the processing speed to the uplink message of terminal 141.Therefore, in the embodiment of the present application, by server 160 to upper
The processing delay of row message is also used as the reference factor of gateway time delay.
In some embodiments, S230 the following steps are included:
S231 determines the Message processing time of the server received each uplink message within the period 3.
The average value of the Message processing time of the uplink message is determined as the processing delay by S232.
In the embodiment of the present application, in order to exclude the influence of enchancement factor, by the period 3, server 160 is to uplink report
The average handling time of text is as processing delay.
In some embodiments, server 160 can adjust the numerical value of period 3 according to the upper hair frequency of uplink message,
To guarantee that the number of uplink message in the period 3 is enough to exclude the influence of random error.
S240 determines the gateway time delay of the forward gateway according to the propagation delay time and the processing delay；Wherein, institute
Gateway time delay is stated for characterizing the speed speed that the server responds the forward gateway.
As shown in Figure 1A, after terminal 141 issues uplink message, uplink message needs to spend one from terminal 141 to gateway 151
It fixes time；After gateway 151 issues response message, response message is also required to take a certain time from gateway 151 to terminal 141.
In the embodiment of the present application, the gateway time delay of forward gateway is determined according to propagation delay time and processing delay.Such as Figure 1A institute
Show, the determination method of this gateway time delay considers transmission duration of the message between gateway 151 and server 160, and clothes
Business device 160 handles the time spent when uplink message.
It in other embodiments, can transmission duration and response message by uplink message from terminal 141 to gateway 151
The reference factor of gateway time delay is also used as from gateway 151 to the transmission duration of terminal 141.
In some embodiments, S240 the following steps are included:
S241 determines practical time delay according to the propagation delay time and the processing delay.
The practical time delay is determined as gateway time delay if the practical time delay is less than or equal to default time delay by S242.
The default time delay is determined as gateway time delay if the practical time delay is greater than default time delay by S243.
In the embodiment of the present application, practical time delay is the sum of propagation delay time and processing delay.If practical time delay is greater than default
Default time delay is determined as gateway time delay by time delay；If practical time delay is less than or equal to default time delay, practical time delay is determined as
Gateway time delay.
LoRaWAN communication protocol allows the setting time delay to terminal to modify, and range is 1-15 seconds.In some embodiments
In, default time delay can be set as 15 seconds, to prevent the downlink window of terminal 141 from opening opportunity beyond protocol requirement.At it
In his embodiment, default time delay can also be set as 15 seconds numerical value below, to prevent terminal 141 from opening setting for downlink window
Fixed response time is too long to cause equipment power dissipation to increase.
In some embodiments, in order to reduce calculation amount, rounding processing can be done to it after acquiring practical time delay,
Integer value is obtained, guarantees that gateway time delay is integer in seconds.
The setting time delay of the terminal is arranged according to the gateway time delay in S250；Wherein, the time delay that sets is described
Terminal, which sends uplink message, to be terminated to the time difference for opening downlink window, and the downlink window is for the terminal reception clothes
The downlink message that business device issues.
In communication process, terminal 141 is likely to be at the networking stage, it is also possible to the stage of communication after networking, in order to
Promote the efficiency that downlink window opens opportunity adjustment, the different phase according to locating for terminal 141 in the embodiment of the present application, to setting
Time delay uses different setting methods.
If terminal be in networking stage, in some embodiments, S210 the following steps are included:
211a, if the terminal is in the networking stage, receive the terminal networking request when, from the terminal with it is described
Optimal gateway is selected at least one gateway between server.
The mark of the optimal gateway is determined as the mark of the forward gateway by 212a.
Here, if terminal 141 is in, the networking stage, there are no determine through which gateway come forwarding terminal 141 and clothes
Be engaged in device 160 between message when, terminal 141 can first to server 160 send network request.Server 160 receives networking
After request, optimal gateway is selected from least one gateway connected to it, in the embodiment of the present application, which is gateway
151.The mark of gateway 151 is the mark of forward gateway.
Those skilled in the art will be seen that, when server 160 determines optimal gateway, need to consider whether terminal 141 is located

t2.Here, the number for the Message processing time that server 160 can be acquired according to the needs of setting adjusts the number of cycle T 3
Value, so that the number of uplink message is enough to exclude the influence of random error in cycle T 3.
S330, server 160 determine the gateway time delay GwDelay of gateway 151.
In the embodiment of the present application, server 160 determines gateway time delay GwDelay according to formula (1):
Here,For the function that rounds up, for example, propagation delay time t1With processing delay t2Summation obtain 13.1, by 13.1 to
Upper rounding then obtains 14.Server 160 is first to propagation delay time t1With processing delay t2Summation, then round up, obtain gateway time delay
The integer value of GwDelay.Then gateway time delay GwDelay and 15 are compared, if it is greater than or be equal to 15, then by 15 be used as net
Close time delay GwDelay；If it is less than 15, then the integer value obtained the rounding is as gateway time delay GwDelay.For example, transmission
Time delay t1With processing delay t2And be 11.3,12 will be obtained by rounding up, since 12 less than 15, it is thus determined that gateway time delay
GwDelay is 12.
