Embodiment
In order to make the object, technical solutions and advantages of the present invention clearer, the present invention is made below in conjunction with attached drawing into
One step it is described in detail, it is clear that described embodiment only part of the embodiment of the present invention, rather than whole implementation
Example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without making creative work
All other embodiment, belongs to the scope of protection of the invention.
The embodiment of the present invention is described in further detail with reference to Figure of description.
In following declarative procedure, first implement to illustrate from the cooperation of end side and server side, finally respectively from
The implementation of end side and server side illustrates, but this does not imply that the two must coordinate implementation, in fact, working as end side
When being performed separately with server side, also solve respectively in the problems of end side and server side.Only both combine
In use, superior technique effect can be obtained.
As shown in Fig. 2, the system that keep-alive duration of the embodiment of the present invention determines：Including terminal 20 and server 21；
Terminal 20, for determining that keep-alive adjusts duration according to the channel status of channel；Definite keep-alive adjustment duration is led to
Know server 21, be adjusted so that the server 21 adjusts keep-alive duration of the duration to channel according to the keep-alive；
Server 21, the keep-alive for receiving the notice of terminal 20 adjust duration；Duration is adjusted to letter according to the keep-alive
The keep-alive duration in road is adjusted.
It should be noted that can determine whether a keep-alive duration base value when terminal 20 and server 21 connect first, and with
Keep-alive duration of the base value as channel, when being adjusted the setting new keep-alive of channel to the base value further according to channel status afterwards
It is long.
Wherein, keep-alive duration base value is one according to emulation, the empirical value of simulation gained.
Before the terminal 20 determines keep-alive adjustment duration according to the channel status of channel, terminal 20 is it needs to be determined that channel
Channel status, determine that the process of channel status is as follows：
The terminal 20 determines the average packet loss ratio of channel and temporary transient packet loss；
The terminal 20 is true according to average packet loss ratio, temporary transient packet loss and average packet loss ratio and the difference of temporary transient packet loss
Determine channel status；
If the average packet loss ratio is more than the temporary transient packet loss, and difference is more than first threshold, and the terminal 20 determines
Channel status is error-free state；
If the average packet loss ratio is less than the temporary transient packet loss, and difference is more than second threshold, and the terminal 20 determines
Channel status is error status.
Need what is illustrated, average packet loss ratio, temporary transient packet loss can be obtained by power rolling average filter algorithm, average packet loss
Rate refers to the long-term transmission status that in a packet loss for setting channel in the period, can reflect channel, sets the period
It can be manually set, can also be by system sets itself, temporary transient packet loss refers to the packet loss of channel at that time, can reflect channel
Transmission status at that time.In certain embodiments, when calculating the period set by average packet loss ratio very in short-term, averagely lose
Bag rate can become into or equivalent to or being defined as packet loss sometime.
Wherein, the average packet loss ratio is more than the temporary transient packet loss, and difference is more than first threshold, illustrates channel at that time
Packet loss it is smaller, transmission status is preferable, thus can be assumed that channel status be error-free state；The average packet loss ratio is less than
The temporary transient packet loss, and difference is more than second threshold, illustrates that the packet drop of channel at that time is serious, transmission status compared with
Difference, therefore can be assumed that channel status is error status；Wherein first threshold and second threshold be according to system status by emulation,
Simulate the empirical value obtained.
In fact, determine that channel status is not limited to according to average packet loss ratio, temporary transient packet loss and average packet loss ratio
Determined with the difference of temporary transient packet loss, the channel status of channel can also be determined according to the length of channel response time, such as
The channel status that channel is determined when the channel response time being more than given threshold is error status, is not more than when the channel response time
Given threshold is to determine that the channel status of channel is error-free state；
The channel status of channel only can also be determined by average packet loss ratio, the magnitude relationship of temporary transient packet loss, such as
When the average packet loss ratio is more than the temporary transient packet loss, it is error-free state to determine channel status, when average packet loss ratio is less than temporarily
When packet loss, it is error status to determine channel status；Determine channel status mode have it is many in, it is every to determine channel shape
The mode of state is suitable for the embodiment of the present invention.
It should be noted that if average packet loss ratio is more than temporary transient packet loss and difference is not more than first threshold, or averagely lose
Bag rate is less than temporary transient packet loss and difference is not more than second threshold, thinks that channel status is unchanged at this time, to terminal 20 and service
The keep-alive duration of channel is without adjustment between device 21.
When channel status is error-free state, the keep-alive duration between terminal 20 and server 21 can be set as one compared with
Long duration value, to reduce between terminal 20 and server 21 to maintain the signal resource of long linkup transmit, saves signaling money
Source；When channel status is error status, the keep-alive duration between terminal 20 and server 21 can be set as one it is less
Duration value, to ensure comparatively fast determine whether the working status of both sides is normal between terminal 20 and server 21, ensures terminal
Normal communication between 20 and server 21.
Wherein, a length of keep-alive duration deviation value or keep-alive duration setting value during the keep-alive adjustment.
When the keep-alive adjusts during a length of keep-alive duration deviation value, the terminal 20 needs definite keep-alive duration is inclined
From value and channel status notice server 21, so that the server 21 deviates according to the channel status and keep-alive duration
Keep-alive duration of the value to the channel is adjusted, this is because keep-alive duration deviation value is a less duration value, is issued
Server 21 sends keep-alive duration deviation value, and server 21 only can not determine how adjustment channel according to keep-alive duration deviation value
Keep-alive duration, so needing also to notify channel status to server 21, can determine to reduce according to channel status server 21
Keep-alive duration still increases keep-alive duration.
Terminal 20 determines that the mode of keep-alive adjustment duration is as follows：
Mode one：The terminal 20 determines channel status according to channel status and the correspondence of keep-alive duration deviation value
Corresponding keep-alive duration deviation value；
The correspondence of channel status and keep-alive duration deviation value, can be the channel status and keep-alive duration being manually set
Between the channel status and keep-alive duration deviation value of one-to-one relationship or default between deviation value one by one
Correspondence, wherein keep-alive duration deviation value can be the empirical values by emulating or simulating acquisition；
For example, the corresponding keep-alive duration deviation value of error-free state is 3 minutes, the corresponding keep-alive duration deviation value of error status
For 2 minutes, if channel status is error-free state, terminal 20 determined that keep-alive duration deviation value is 3 minutes；If channel status is
Wrong state, then terminal 20 determine keep-alive duration deviation value be 2 minutes.
Mode two：The terminal 20 determines the channel status of channel according to channel status and the correspondence of keep-alive duration
Corresponding keep-alive duration setting value；
The correspondence of channel status and keep-alive duration, can be the channel status and keep-alive duration setting value being manually set
Between one-to-one relationship or one-to-one corresponding between the channel status and keep-alive duration setting value of default close
System, wherein keep-alive duration setting value can be the empirical value by emulating or simulating acquisition；
For example, the corresponding keep-alive duration setting value of error-free state is 7 minutes, the corresponding keep-alive duration setting value of error status
Deviation value is 7 minutes, if channel status is error-free state, terminal 20 determines that keep-alive duration setting value is 4 minutes；If channel shape
State is error status, then terminal 20 determines that keep-alive duration setting value is 3 minutes.
It should be noted that if channel status is unchanged, between terminal 20 and server 21 the keep-alive duration of channel not into
Row adjustment, then its corresponding keep-alive duration deviation value is zero, and keep-alive duration setting value is the keep-alive duration base value of channel.
After terminal 20 determines keep-alive adjustment duration, keep-alive adjustment duration is notified that advice method has to server 21
The following two kinds mode：
Definite keep-alive duration deviation value and the channel status are notified server 21 by mode one, terminal 20；
Terminal 20 can use PINGREQ as shown in Figure 3（Keep-alive is asked）Message format by keep-alive duration deviation value and
The channel status notifies server 21；
It is existing PINGREQ message formats in Fig. 4, PINGREQ messages are 2 bits, wherein containing MQTT control reports
Literary type, reserved bit and residue length position, residue length position do not have practical significance, the main function of existing PINGREQ messages
It is the long connection maintained at the end of keep-alive duration with server 21；
It is the PINGREQ message formats newly defined in Fig. 3, PINGREQ messages are 1 bit, wherein containing MQTT controls
The binary numeral of type of message, channel status bit and keep-alive duration deviation value, wherein the numerical value of the 4th~7 represents MQTT controls
Type of message processed, is 12 for the corresponding numerical value of keep-alive request message, and binary numeral 1100, the 3rd is channel status bit,
Corresponding numerical value represents channel status, is error-free state when can set channel status bit as 0, is when channel status bit is 1
Wrong state, the numerical value of the 0th~2 represent keep-alive duration deviation value, and the unit of keep-alive duration deviation value can be set as minute；
For example, if channel status is error-free state, keep-alive duration deviation value is 3 minutes, then the content of PINGREQ messages is
For 11000011；If channel status is error status, keep-alive duration deviation value is 2 minutes, then the content of PINGREQ messages is
11001010；
It should be noted that if channel status is unchanged, corresponding keep-alive duration deviation value is zero, then PINGREQ messages
Middle channel status bit can be that 0 content for being alternatively 1, PINGREQ messages is 11000000 or 11001000.
Definite keep-alive duration setting value and the channel status are notified server 21 by mode two, terminal 20；
Terminal 20 can use PINGREQ message formats as shown in Figure 5 that keep-alive duration setting value is notified server 21,
It is the PINGREQ message formats newly defined in Fig. 5, PINGREQ messages are 1 bit, wherein MQTT control type of messages are contained,
The binary numeral of keep-alive duration setting value, wherein the numerical value of the 4th~7 represents MQTT control type of messages, please for keep-alive
It is 12 to seek the corresponding numerical value of message, and the numerical value that binary numeral is the 1100, the 0th~3 represents the setting of keep-alive duration, keep-alive duration
The unit of setting value can be set as minute；
For example, if keep-alive duration setting value is 7 minutes, the content of PINGREQ messages is 11000111.
Need what is illustrated, in the definite letter of terminal 20 when terminal 20 determines that channel keep-alive residual time length is not more than given threshold
The keepalive state in road, and then determine that keep-alive adjusts duration according to the channel status of channel；Wherein, given threshold can be taking human as setting
Put, can also system set, such as given threshold can be zero, determine channel keep-alive residual time length no more than setting when terminal 20
When determining threshold value, namely, it is necessary to when maintaining long connection with server 21 at the end of channel keep-alive duration, terminal 20 determines the letter of channel
Road state, and then determine that keep-alive adjusts duration according to the channel status of channel, and definite keep-alive adjustment duration is notified to clothes
Business device 21.
Server 21 can be received the keep-alive adjustment duration that terminal 20 notifies by following two modes：
Mode one, server 21 receive the channel status and keep-alive duration deviation value of the channel of the notice of terminal 20；
Server 21 receives PINGREQ messages as shown in Figure 3, and the channel status and keep-alive duration for determining channel deviate
Value.For example, the content that server 21 receives PINGREQ messages is 11000011, the numerical value that server 21 obtains the 3rd is 0, really
The channel status for determining channel is error-free state, and the numerical value that server 21 obtains the 0th~2 is 011, determines keep-alive duration deviation value
For 3 minutes；The content that server 21 receives PINGREQ messages is 11001010, and the numerical value that server 21 obtains the 3rd is 1, really
The channel status for determining channel is error status, and the numerical value that server 21 obtains the 0th~2 is 010, determines keep-alive duration deviation value
For 2 minutes.
Mode two, server 21 receive the keep-alive duration setting value of the notice of terminal 20；
Server 21 receives PINGREQ messages as shown in Figure 5, determines to work as keep-alive duration setting value.For example, server 21
The content for receiving PINGREQ messages is 11000111, and the numerical value that server 21 obtains the 0th~3 is 0111, determines keep-alive duration
Setting value is 7 minutes.
Server 21, can be according to the following two kinds mode to channel after the keep-alive adjustment duration of the notice of terminal 20 is received
Keep-alive duration is adjusted：
Mode one, server 21 adjust the keep-alive duration of channel according to the channel status and keep-alive duration deviation value of channel；
If channel status is error-free state, the server 21 is by channel keep-alive duration base value and keep-alive duration deviation value
Channel keep-alive duration is used as with value；
If channel status is error status, the server 21 is by channel keep-alive duration base value and keep-alive duration deviation value
Difference is as channel keep-alive duration.
For example, channel keep-alive duration base value is 5 minutes, 21 channel status of server is error-free state, and keep-alive duration is inclined
Be 3 minutes from value, then server 21 by channel keep-alive duration base value 5 minutes and keep-alive duration deviation value 3 minutes and be worth namely 8
Minute is used as channel keep-alive duration；Channel keep-alive duration base value is 5 minutes, and 21 channel status of server is error status, and is protected
Duration deviation value living is 2 minutes, then server 21 was by channel keep-alive duration base value 5 minutes and keep-alive duration deviation value 2 minutes
Difference namely 3 minutes conduct channel keep-alive durations.
Mode two, server 21 adjust the keep-alive duration of channel according to keep-alive duration setting value；
The server 21 is using the keep-alive duration setting value as channel keep-alive duration.
For example, server 21 determines that keep-alive duration setting value is 7 minutes, then server 21 is by the keep-alive duration setting value
It is used as channel keep-alive duration within 7 minutes.
After server 21 adjusts channel keep-alive duration, server 21 can use as shown in Figure 6
PINGRESP（Keep-alive responds）Message format sends feedback information to terminal 20；
Fig. 7 is existing PINGRESP message formats, and PINGRESP messages are 2 bits, wherein containing MQTT control reports
Literary type, reserved bit and residue length position, the effect of wherein reserved bit are if XXX, and residue length position does not have practical significance,
The main function of existing PINGRESP messages is to send PINGREQ to terminal 20 to feed back, and maintains server 21 and terminal 20
Between connection.
The PINGRESP message formats newly defined for the embodiment of the present invention in Fig. 7, PINGRESP messages are 1 bit, wherein
MQTT control type of messages, the binary numeral of reserved bit are contained, wherein the numerical value of the 4th~7 represents MQTT control messages
Type, is 13 for the corresponding numerical value of keep-alive response message, the numerical value that binary numeral is the 1101, the 0th~3 is reserved bit.
As shown in figure 8, terminal includes in the system that present specification embodiment keep-alive duration determines：First processing module 800
