Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear
Chu, it is fully described by.
Embodiment one
The embodiment of the present invention provides a kind of internet of things data transmission method, applied to internet-of-things terminal, such as Fig. 1
Shown, the internet of things data transmission method includes：
Step 101, transmission data to be sent.
Example, can be first by number to be sent when internet-of-things terminal is currently needed for sending data to be sent
Cached according to multiple data blocks are divided into, read a data block each second and be transmitted, now sent and treat
The message transmission rate for sending data is ratio of the data volume with 1 second time of data block.Wherein, it is described
The data volume of multiple data blocks is equal.
Step 102, determine whether Current Communications Status is CELL_DCH patterns.
Example, in 3G network can transmission services data pattern definition be CELL_DCH (Cell
Dedicated Channel, cell dedicated channel) pattern and CELL_FACH (Cell Forward Access
Channel, cell forward access channel) pattern.The CELL_DCH patterns are high business data transmission
Pattern, when internet-of-things terminal is in CELL_DCH patterns, network, which is that internet-of-things terminal distribution is special, to be passed
Defeated channel, for transmission services data, so as to quick transmission services data；In traffic data rate
During less than handoff threshold, internet-of-things terminal can be switched to CELL_FACH patterns, release distribution by network
To the dedicated channel of internet-of-things terminal, then common signal channel is used, low message transmission rate transmission services data,
When the traffic data rate of internet-of-things terminal is higher than handoff threshold, then it is switched to CELL_DCH patterns,
Dedicated channel is distributed again.
Specifically, because internet-of-things terminal is before data to be sent are sent, it is impossible to know present access subzone
Handoff threshold, and then can not know when sending data to be sent according to current message transmission rate, communication
State is CELL_DCH patterns or CELL_FACH patterns, therefore when internet-of-things terminal is treated in transmission
When sending data, current communications status can be detected in time, in order to which Current Communications Status is
CELL_DCH patterns, adjust message transmission rate in time.
If step 103, Current Communications Status are CELL_DCH patterns, reduction sends the data to be sent
Message transmission rate so that communications status is from CELL_DCH pattern switchings to CELL_FACH patterns.
Example, if Current Communications Status is CELL_DCH patterns, illustrate the number of internet-of-things terminal currently
It is larger according to transmission rate, exceed the handoff threshold of current area, it is therefore desirable to gradually reduce data transfer speed
Rate, until message transmission rate is less than the handoff threshold of current area so that the communications status of internet-of-things terminal
From CELL_DCH pattern switchings to CELL_FACH patterns, and keep low rate low power consumption transmission state.
So, when internet-of-things terminal under 3G network communications status for CELL_DCH patterns rather than
, can be by reducing the message transmission rate of internet-of-things terminal so that Internet of Things during CELL_FACH patterns
The communications status of terminal causes Internet of Things from CELL_DCH pattern switchings to CELL_FACH patterns
Network termination can be in CELL_FACH patterns all the time, realize the low speed of internet-of-things terminal under 3G network
Rate low power consumption data is transmitted, and has saved the communication resource.
Further, if Current Communications Status is CELL_FACH patterns, Internet of Things can be monitored in real time whole
The communications status at end；Determine communications status whether from CELL_FACH pattern switchings to CELL_DCH moulds
Formula；If communications status is from CELL_FACH pattern switchings to CELL_DCH patterns, the data are reduced
Transmission rate so that communications status is from CELL_DCH pattern switchings to CELL_FACH patterns.
Example, if Current Communications Status is CELL_FACH patterns, illustrate the number of internet-of-things terminal currently
It is smaller according to transmission rate, not less than the handoff threshold of current area, therefore current data transfer can be used
Speed continues to send data to be sent, but in practical application, the cell of 3G network covering is numerous, Mei Ge little
The handoff threshold in area is different, and some community user numbers are less, so handoff threshold can be with relatively low；Some cells
Number of users is more, so handoff threshold is higher.If internet-of-things terminal sends number using same message transmission rate
According to when carry out cell switching, it is likely that relatively low small of handoff threshold can be switched to from the higher cell of handoff threshold
Area, then be in CELL_FACH patterns before the switching of internet-of-things terminal cell, may be from after cell switching
CELL_FACH patterns are changed into CELL_DCH patterns, therefore internet-of-things terminal can monitor current institute in real time
The pattern at place, in order to determine Current Communications Status whether from CELL_FACH pattern switchings to
CELL_DCH patterns.If Current Communications Status is from CELL_FACH pattern switching to CELL_DCH
Pattern, illustrates that the current message transmission rate of internet-of-things terminal is larger, has exceeded the handoff threshold of current area,
Therefore need to gradually reduce message transmission rate, until handoff threshold of the message transmission rate less than current area,
So that the communications status of internet-of-things terminal is switched to CELL_FACH patterns again from CELL_DCH patterns,
And keep low rate low power consumption transmission state.
Optionally, when sending data to be sent, data rate thresholding can be obtained first, and according to described
Data rate thresholding, obtains the message transmission rate, then according to the message transmission rate, sends institute
State data to be sent.
Example, the data rate thresholding can be configured based on experience value, represent internet-of-things terminal from
When CELL_FACH pattern switchings are to CELL_DCH patterns, or internet-of-things terminal is from CELL_DCH moulds
The critical value of speed when formula is switched to CELL_FACH patterns., can be in internet-of-things terminal during initialization
The data rate thresholding of acquiescence is pre-set, now the data rate thresholding can be those skilled in the art
Empirical value, internet-of-things terminal first time network in use, the data rate thresholding of acquiescence can be read.
During the use of internet-of-things terminal, because internet-of-things terminal may frequently be cut between each cell
Change, therefore data rate thresholding is dynamic change, if internet-of-things terminal shuts down suddenly during use,
Data rate thresholding during last shutdown can be obtained after starting shooting again.
Optionally, in order to ensure that internet-of-things terminal is continuously in low-power consumption low rate in 3G network
CELL_FACH patterns, the message transmission rate of internet-of-things terminal needs to maintain reduced levels, therefore in root
According to the data rate thresholding, when obtaining the message transmission rate, it can obtain less than or equal to data speed
The message transmission rate of rate thresholding sends data.Specifically, speed rule can be set during initialization, it is described
Speed rule indicates the relation of message transmission rate and data rate thresholding, for example, it is assumed that speed rule refers to
Show that message transmission rate is equal to data rate thresholding, if data rate thresholding is 100k/s (kilobytes/second),
Then message transmission rate is also 100k/s；Or, speed rule indicates that message transmission rate is data rate door
The 80% of limit, if data rate thresholding is 100k/s, message transmission rate is 80k/s.It is preferred that, data
Transmission rate is less than data rate thresholding.
Example, data to be sent can be sent according to the message transmission rate got.For example, can be first
First according to the message transmission rate, the data to be sent are divided into multiple data blocks and cached, often
The data volume of individual data block is equal with the data volume that each second that the message transmission rate is limited can send,
Then the data to be sent are sent according to the data block.For example, it is assumed that data rate thresholding is 100k/s,
After the data to be sent for needing to be transmitted are got, data to be sent can be divided into and be less than or wait
Stored in 100k data block, can be according to above-mentioned speed rule during specific division.When speed rule refers to
When showing that message transmission rate is equal to data rate thresholding, data to be sent can be divided into the number equal to 100k
Stored according to block；, can be with when speed rule indicates 80% that message transmission rate is data rate thresholding
The data block that data to be sent are divided into 80k is stored.Now, internet-of-things terminal is only needed to each second
Read a data block to be transmitted, you can ensure that transmission rate is met and require.
Optionally, if Current Communications Status is from CELL_FACH pattern switchings to CELL_DCH patterns,
The message transmission rate can be reduced first, according to the message transmission rate after reduction, sent described pending
Data are sent, it is then determined that whether communications status is from CELL_DCH pattern switchings to CELL_FACH patterns,
If communications status is not from CELL_DCH pattern switchings to CELL_FACH patterns, continue to reduce the number
According to transmission rate, until Current Communications Status is from CELL_DCH pattern switchings to CELL_FACH patterns.
Example, internet-of-things terminal is from CELL_FACH pattern switchings to CELL_DCH patterns, explanation
The message transmission rate of current internet-of-things terminal is larger, more than the handoff threshold of current area, in order that obtaining thing
Networked terminals are switched to CELL_FACH patterns again from CELL_DCH patterns, can reduce Internet of Things
The message transmission rate of terminal, but internet-of-things terminal can not know the handoff threshold of current area, therefore nothing
Message transmission rate is directly reduced to less than or equal to the handoff threshold of cell by method, so in practical application,
Message transmission rate can be gradually reduced, is often reduced once, just whether the communications status of detection internet-of-things terminal
From CELL_DCH pattern switchings to CELL_FACH patterns, if reduction after internet-of-things terminal communication
State is still maintained CELL_DCH patterns, then continues to reduce message transmission rate, then detect again
The communications status of internet-of-things terminal, until Current Communications Status from CELL_DCH pattern switchings to
CELL_FACH patterns.
Further, if Current Communications Status is from CELL_DCH pattern switchings to CELL_FACH moulds
Formula, according to the message transmission rate after the reduction, updates the data rate thresholding.
Example, when internet-of-things terminal from CELL_DCH patterns is switched to CELL_FACH patterns again
Afterwards, illustrate last time reduce after message transmission rate already less than or equal to current area handoff threshold,
Message transmission rate after being reduced using last time enables to internet-of-things terminal to maintain CELL_FACH
Pattern, the message transmission rate after can now being reduced according to last time, updates the data of internet-of-things terminal
Rate threshold, during in order to internet-of-things terminal transmission services data next time, according to the data rate after renewal
Thresholding, obtains message transmission rate.
The embodiments of the invention provide a kind of internet of things data transmission method, including：Send data to be sent；
Whether determine Current Communications Status is cell dedicated channel CELL_DCH patterns；If Current Communications Status is
CELL_DCH patterns, reduction sends the message transmission rate of the data to be sent so that communications status from
CELL_DCH pattern switchings are to cell forward access channel CELL_FACH patterns.Compared to prior art,
When the communications status of internet-of-things terminal under 3G network is CELL_DCH patterns rather than CELL_FACH moulds
, can be by reducing the message transmission rate of internet-of-things terminal so that the communications status of internet-of-things terminal during formula
From CELL_DCH pattern switchings to CELL_FACH patterns, and then enable internet-of-things terminal all the time
In CELL_FACH patterns, the low rate low power consumption data for realizing internet-of-things terminal under 3G network is passed
It is defeated, save the communication resource.
Embodiment two
The embodiment of the present invention provides a kind of internet of things data transmission method, applied to internet-of-things terminal, such as Fig. 2
Shown, methods described includes：
Step 201, acquisition data rate thresholding, perform step 202.
Example, internet-of-things terminal can obtain the data rate thresholding of acquiescence, or obtain last shutdown
When data rate thresholding.
Step 202, according to the data rate thresholding, cache data to be sent, perform step 203.
Example, data to be sent can be divided into multiple data blocks and be stored, the data block it is big
It is small to be adjusted according to data rate thresholding.For example, it is assumed that data rate thresholding is 100k/s, obtaining
Get after the data to be sent for needing to be transmitted, data to be sent can be divided into and be less than or equal to
100k data block is stored.Specifically, can be divided according to speed rule.Assuming that speed is regular
Indicate that message transmission rate is equal to data rate thresholding, data to be sent can be now divided into equal to 100k
Data block stored；Assuming that speed rule indicates 80% that message transmission rate is data rate thresholding,
The data block that now data to be sent can be divided into 80k is stored.
Step 203, according to the data rate thresholding, obtain message transmission rate, perform step 204.
Example, can be according to default speed rules Acquires data transmission rate.Assuming that data rate thresholding
For 100k/s, indicate message transmission rate equal to data rate thresholding, message transmission rate if speed is regular
Also it is 100k/s；If speed rule indicates 80% that message transmission rate is data rate thresholding, data are passed
Defeated speed is 80k/s.It is preferred that, message transmission rate is less than data rate thresholding.
Step 204, according to the message transmission rate, send the data to be sent, perform step 205.
Example, in order to meet the message transmission rate obtained according to data rate thresholding, internet-of-things terminal can
A data block is read with each second from caching to be transmitted.
Whether step 205, detection Current Communications Status are from CELL_FACH pattern switching to CELL_DCH
Pattern；If Current Communications Status is from the CELL_FACH pattern switchings to CELL_DCH patterns,
Perform step 206；If Current Communications Status is not from CELL_FACH pattern switchings to CELL_DCH moulds
Formula, performs step 210.
Example, when internet-of-things terminal starts transmission services data, can detect first communications status whether be
CELL_DCH patterns, when communications status is CELL_DCH patterns, reduce message transmission rate, and
Detect terminal whether from CELL_DCH pattern switchings to CELL_FACH patterns, if terminal from
CELL_DCH pattern switchings then continue according to the message transmission rate after reduction to CELL_FACH patterns
Data to be sent are sent, if terminal is not from CELL_DCH pattern switchings to CELL_FACH patterns,
Continue reduce message transmission rate, until Current Communications Status from CELL_DCH pattern switchings to
CELL_FACH patterns；When communications status is CELL_FACH patterns, communications status is continued to monitor,
If the communications status for detecting internet-of-things terminal changes, determine internet-of-things terminal whether be from
CELL_FACH pattern switchings are to CELL_DCH patterns.
Step 206, the reduction message transmission rate, perform step 207.
Example, if Current Communications Status is from the CELL_FACH pattern switchings to CELL_DCH
Pattern, illustrates that now message transmission rate is larger, in order that obtaining internet-of-things terminal from CELL_DCH patterns
Again CELL_FACH patterns are switched back into, message transmission rate can be gradually reduced.For example, can be according to
10k/s difference, gradually reduces message transmission rate.Assuming that initial data transmission rate is 100k/s, then the
Message transmission rate after once reducing is 90k/s.
Step 207, according to the message transmission rate after reduction, send the data to be sent, perform step
208。
Example, after reduction message transmission rate, the data to be sent for having cached and not sent can be pressed
Repartitioned according to the message transmission rate after reduction, be divided into the number matched with the message transmission rate after reduction
According to block so that internet-of-things terminal, which reads a data block each second and is transmitted, can meet the data after reduction
Transmission rate.Assuming that message transmission rate is 90k/s after reduction, then it will can cache and treating of not sending
Send data and be divided into multiple 90k data block and cached, internet-of-things terminal can be to read one each second
Data block is transmitted, and now the message transmission rate of internet-of-things terminal is 90k/s.
Whether step 208, detection are current from CELL_DCH pattern switchings to CELL_FACH patterns；If
Currently from CELL_DCH pattern switchings to CELL_FACH patterns, step 209 is performed；If currently not
From CELL_DCH pattern switchings to CELL_FACH patterns, step 206 is performed.
Example, because internet-of-things terminal can not obtain the handoff threshold of current area, therefore can not directly by
Message transmission rate is reduced to less than or equal to the handoff threshold of cell, so in practical application, can be progressively
Reduce message transmission rate, often reduce once, just detection internet-of-things terminal communications status whether from
CELL_DCH pattern switchings to CELL_FACH patterns, if after reduction internet-of-things terminal communications status
Still CELL_DCH patterns are maintained, then continues to reduce message transmission rate, Internet of Things is then detected again
The communications status of network termination, until Current Communications Status is from CELL_DCH pattern switching to CELL_FACH
Pattern.
Step 209, according to the message transmission rate after the reduction, update the data rate thresholding, hold
Row step 202.
Example, if current from CELL_DCH pattern switchings to CELL_FACH patterns, illustrate most
Handoff threshold of the message transmission rate already less than current area after once reducing afterwards, is dropped using last time
Message transmission rate after low enables to internet-of-things terminal to maintain CELL_FACH patterns, now can be with
Message transmission rate after being reduced according to last time, updates the data rate thresholding of internet-of-things terminal, so as to
When internet-of-things terminal transmission services data next time, according to the data rate thresholding after renewal, data are obtained
Transmission rate.
Step 210, it is continuing with the message transmission rate, sends the data to be sent.
Example, if the current communications status of internet-of-things terminal for not from CELL_FACH pattern switchings to
CELL_DCH patterns, illustrate that the current message transmission rate of internet-of-things terminal can be so that internet-of-things terminal be tieed up
Hold in CELL_FACH patterns, be continuing with the message transmission rate, send the data to be sent.
It should be noted that the sequencing of internet of things data transmission method step provided in an embodiment of the present invention
Can suitably it be adjusted, step according to circumstances can also accordingly be increased and decreased, any to be familiar with the art
Technical staff the invention discloses technical scope in, the method that can readily occur in change should all cover
Within protection scope of the present invention, therefore repeat no more.
The embodiments of the invention provide a kind of internet of things data transmission method, compared to prior art, if 3G
The communications status of internet-of-things terminal is from CELL_FACH pattern switchings to CELL_DCH patterns under network,
Can be by reducing the message transmission rate of internet-of-things terminal so that the communications status of internet-of-things terminal from
CELL_DCH patterns are switched to CELL_FACH patterns again, and then internet-of-things terminal is continued
In CELL_FACH patterns, the low rate low power consumption data for realizing internet-of-things terminal under 3G network is passed
It is defeated, save the communication resource.
