Standby, vendor equipment not all first all has jam control function, secondly, even if different vendor's distinct device is provided with congestion
Controlling mechanism, but each standard transmission congestion control starting strategy of each manufacturer, control paces, control target is also different, practical
Even there is the transmission bandwidth or processing capacity that some website is conceded in operation, is seized at once by other equipment；Whole control
Hard to work, cause current phenomenon to be: message amount excessively exceeds processing capacity or flow beyond centre on transmission network
Each node is transmitted to receive buffering or send buffer capacity, cause the message of high priority equally show high Loss Rate and it is big when
Prolong, normal business is impacted, especially working hour does not get through phone and often results in a large amount of complaints or customer churn.

When the transmission losing rate in newest detection cycle is higher than setting thresholding, base station and controller are led according to a certain percentage
It is dynamic to abandon part low priority traffice message, it reduces IUB interface and transmits flow；
When the transmission losing rate in newest detection cycle is higher than setting thresholding, the message important for IUB interface, base station
Repeatedly interval is actively carried out on IUB interface with controller to send.
Subsequent, in next detection cycle, continuation is started the cycle over from S101 step to be detected and is operated.
As another embodiment, the message transmissions performance parameter includes: service message transmission losing rate and time delay,
The service message transmission performance parameter reaches that preset condition includes: the service message transmission losing rate and time delay is above pair
The setting thresholding answered.
Specific control process is as follows:
Firstly, the IUB interface transmission quality being periodically detected between base station and controller, count transmission losing rate and when
Prolong.
When in newest detection cycle transmission losing rate and time delay be above corresponding setting thresholding when, base station and controller
Part low priority traffice message is actively abandoned according to a certain percentage, is reduced IUB interface and is transmitted flow；
When in newest detection cycle transmission losing rate and time delay be above corresponding setting thresholding when, for IUB interface
Important message, base station and controller actively carry out repeatedly interval on IUB interface and send.
Subsequent, in next detection cycle, continuation is started the cycle over from S101 step to be detected and is operated.
It should be noted that in other embodiments, it is also contemplated that message transmissions performance parameter only includes time delay
Situation, i.e., using time delay whether reach predetermined threshold value as triggering control service message send or abandon Rule of judgment.
Further, it is also contemplated that whether currently practical transmission bandwidth is higher than the threshold value of setting, to improve message
The accuracy of control.It is implemented as follows:
When the transmission losing rate in newest detection cycle is higher than setting thresholding, the currently practical of the IUB interface is judged
Transmission bandwidth whether be higher than the threshold value of setting；If currently practical transmission bandwidth is higher than the threshold value of setting, institute is controlled
It states base station and controller and abandons the default low priority traffice message in part actively by preset ratio to reduce IUB interface transport stream
Amount.
The present embodiment through the above scheme, by the IUB interface transmission quality being periodically detected between base station and controller,
According to the IUB interface transmission quality statistical service message transmissions performance parameter, the service message within the current detection period is passed
When defeated performance parameter reaches preset condition, the base station and controller are controlled by preset ratio and abandons the default low priority industry in part
Business message transmits flow to reduce IUB interface, and, it controls the base station and controller and carries out default Gao You on IUB interface
The multiple interval of first grade service message is sent, and using confrontation IUB interface bad transmission scheme used in the present invention, is working as front
Under the high Loss Rate of point operator transmission, high time delay status, when can reduce the Loss Rate of the important message of IUB interface, and not increase
Prolong, promote service feature, reduce cutting off rate and call completion ratio, thus promotes quality of service and user satisfaction.
As shown in figure 4, second embodiment of the invention proposes a kind of data transmission method, it is based on above-mentioned first embodiment, institute
State method further include:
Step S103, the service message transmission performance parameter within the current detection period are reduced to not up to preset condition
When, it controls the base station and controller stops abandoning the default low priority traffice message in part and stops carrying out default high preferential
The multiple interval of grade service message is sent.
Above-mentioned steps S102 is S1021, and the service message transmission performance parameter within the current detection period reaches default item
When part, the base station and controller are controlled by preset ratio and abandons the default low priority traffice message in part to reduce IUB interface
Transmit flow, and, control the base station and controller carried out on IUB interface default high-priority service message it is multiple between
Every transmission.
Compared to above-described embodiment, the present embodiment further includes the processing side after follow-up business message transmissions performance parameter reduces
Case.
Specifically, by taking message transmissions performance parameter includes service message transmission losing rate and time delay as an example, when newest detection
After transmission losing rate and time delay in period are reduced to certain thresholding, base station and controller stopping actively abandoning part low priority
The multiple interval that service message and stopping actively carrying out important message is sent.
Subsequent, in next detection cycle, continuation is started the cycle over from S101 step to be detected and is operated.
Using confrontation IUB interface bad transmission scheme used in the present invention, lost in the height of current portions operator transmission
Under mistake rate, high time delay status, the Loss Rate of the important message of IUB interface can be reduced, and do not increase time delay, promote service feature, drop
Thus low cutting off rate and call completion ratio promote quality of service and user satisfaction.
The application scenarios of the embodiment of the present invention detailed below:
Embodiment 1
Certain South America operator, a transmission network support all 3G, 4G equipment, and wireless device derives from three manufacturers,
Since certain model Transmission Convergence equipment is old, packet switching capability is limited, has been unable to satisfy existing net demand, but in a short time can not also be into
The whole net replacement of the row equipment, it is good from the apparent evening index of single vendor equipment monitoring transmission network presentation, daytime index error spy
Point, even the Packet-loss ratio of high priority on daytime is still up to 10~20% or more, delay variation is unstable, and tens is supreme
Hundred milliseconds, it is difficult daytime to get through, it is also very low that the RRC observed connects into power, between only 30~40%.
After single vendor equipment is using transmission congestion control, it is periodically detected transmission quality, the period of high Loss Rate, is actively lost
Part low priority message is abandoned, IUB interface entirety flow is reduced, RRC is not significantly changed and connects into power index, is difficult to get through electricity
The status of words is not clearly better, and reason is single vendor equipment using after congestion control, and overall transfer flow has to a certain degree
Decline, but IUB interface Loss Rate improves unobvious, canonical process as shown in Figure 3, and in the process, NodeB and RNC need
5 bag datas are transmitted on IUB interface, as soon as any bag data is lost on IUB interface, whole flow process is had failed, and is needed continuous 5 times
Success could complete a RRC connection procedure, by probability calculation, be 5 powers of single success rate, successfully require very single
It is high.
Using scheme used in the present invention, process is as follows:
Step 1, by 5 minute period, the transmission quality of NodeB and RNC detection IUB interface, count transmission losing rate and when
Prolong.
Step 2, after the transmission losing rate rising of IUB interface in nearest 5 minutes reaches certain thresholding 5%, if currently
50%, the NodeB and RNC that the practical transmission bandwidth of IUB interface is higher than setting bandwidth are actively abandoned in the ratio of setting bandwidth 10%
The message of interaction service in background reduces IUB interface and transmits total flow.
Step 3, when in nearest 5 minutes IUB interface transmission losing rate rising reach certain thresholding 5% after, NodeB and
RNC is spaced 10ms on IUB interface and repeats to send 2 times for the important message of IUB interface described in Fig. 3, initiative recognition.
Step 4, when in nearest 5 minutes IUB interface transmission losing rate decline reach certain thresholding 5% after, NodeB and
RNC stops actively abandoning part low priority traffice message and stops the multiple interval transmission for actively carrying out important message.
Continuation is started the cycle over from step 1 to be periodically detected and is operated.
As examples detailed above it is found that using method shown in the present invention, the period is lost in IUB interface height, is not simple drop
Low transmitted traffic, while also according to the concrete condition of IUB interface network, the important message of IUB interface is repeatedly repeated intervally to send, such as
Shown in Fig. 3, in 2 Fig. 3 of interval 10ms transmission after important message, once received due to any in 2 times, single interaction is lost
The probability lost is decreased obviously, and is reduced to 4% from 20%, the successful probability of continuous 5 single pass is substantially increased.Using the present invention
Shown in method, in certain South America carrier network after practice, although IUB interface Loss Rate is not obviously changed on daytime
It is kind, but user's call completion ratio is substantially increased, and user no longer complains can not get through daytime.
Embodiment 2
Certain Domestic Carriers a, transmission network, open 3G network first, then as 4G network starts to build, in original
Call number man manufacturer on some transmission networks, with the rising of number of users and the decline of rate, flow is substantially increased, transmission network
Network gradually monitors that section ports bandwidth is insufficient, and the characteristics of due to mobile network, the insufficient port of bandwidth is simultaneously not fixed, and only
Occur in a small number of periods, but the period is not fixed, and transmits the dilatation of whole net there are also to be designed and planning, the transmission matter that now net detects
At the time of more severe, also close to 10%, customer complaint amount is begun to ramp up Loss Rate amount.
In this scenario, the website that selection has occurred that transmission degrades implements scheme used in the present invention, and process is as follows:
Step 1, by 5 minute period, the transmission quality of NodeB and RNC detection IUB interface, count transmission losing rate and when
Prolong.
Step 2, after the transmission losing rate rising of IUB interface in nearest 5 minutes reaches certain thresholding 5%, if currently
75%, the NodeB and RNC that the practical transmission bandwidth of IUB interface is higher than setting bandwidth are actively abandoned in the ratio of setting bandwidth 10%
The message of interaction service in background reduces IUB interface and transmits total flow.
Step 3, when in nearest 5 minutes IUB interface transmission losing rate rising reach certain thresholding 5% after, NodeB and
RNC is spaced 50ms on IUB interface and repeats to send 2 times for the important message of IUB interface described in Fig. 2, initiative recognition.
Step 4, when in nearest 5 minutes IUB interface transmission losing rate decline reach certain thresholding 5% after, NodeB and
RNC stops actively abandoning part low priority traffice message and stops the multiple interval transmission for actively carrying out important message.
Continuation is started the cycle over from step 1 to be periodically detected and is operated.
Using method shown in the present invention, although with case 1 cause IUB transmission quality decline the reason of it is different with performance,
But after the website actual deployment that IUB transmission degrades occurs in selection, RRC connects into power index and restores normal, and phone call completion ratio is protected
It holds on good level.
Accordingly, data transmission device embodiment of the present invention is proposed.
Data transmission device of the present invention includes:
Parameter detection module, the IUB interface transmission quality for being periodically detected between base station and controller, according to described
IUB interface transmission quality statistical service message transmissions performance parameter, the service message transmission performance parameter include at least: business
Message transmissions Loss Rate；
Transmission control module reaches preset condition for the service message transmission performance parameter within the current detection period
When, it controls the base station and controller and service message is sent or abandoned with preset rules according to pre-set priority.
Specifically, transmission control module, the service message transmission performance parameter being also used within the current detection period reach
When preset condition, the base station and controller are controlled by preset ratio and abandons the default low priority traffice message in part to reduce
IUB interface transmits flow, and, it controls the base station and controller and carries out default high-priority service message on IUB interface
Multiple interval send.
Further, the transmission control module is also used to the service message transmission performance parameter within the current detection period
When reaching preset condition, judge whether the currently practical transmission bandwidth of the IUB interface is higher than the threshold value of setting；If being higher than
The threshold value of setting then controls the base station and controller by preset ratio and abandons the default low priority traffice message in part to drop
Low IUB interface transmits flow.
