Description of drawings
Fig. 1 is the flow chart of the method for the invention.
Embodiment
Core concept of the present invention is: at the existing technical problem of control strategy of existing business fixed configurations BLERTarget, the BLERTarget of miscellaneous service can dynamically be adjusted according to the loading condition of sub-district.Especially when the user of sub-district is fewer, perhaps when the load of sub-district is low, such as off-peak period, by reducing BLERTarget, can improve the message transmission rate of data service or the speech quality of speech business, corresponding QoS is improved, and the resource of reasonable use sub-district more is as power resource.When cell load rate during greater than the threshold value set, improve BLERTarget, can guarantee that the sub-district provides service to new user.
For the present invention there being further understanding, method of the present invention is described in detail below in conjunction with accompanying drawing.
The specific implementation of the method for the invention may further comprise the steps as shown in Figure 1:
Step 11: threshold ones and the wealthy family's limit value of setting the cell load rate.
In order to implement the dynamic control of BLERTarget in the WCDMA system, the sub-district should be set threshold ones and wealthy family's limit value of cell load rate according to actual conditions, and this threshold value is a percentage usually;
The threshold ones of described cell load rate and wealthy family's limit value can be determined and proofread and correct by the simulated measurement mode;
The threshold ones of setting the cell load rate in the present embodiment is 20%, and wealthy family's limit value is 40%.
Step 12: measure sub-district present load rate.
For the tracing and monitoring cell load, as required sub-district present load rate is measured at any time.
Step 13: whether judge sub-district present load rate less than threshold ones, if less than, then execution in step 14; Otherwise, execution in step 15.
The cell load rate threshold ones of sub-district present load rate and setting is compared, if less than threshold ones, then execution in step 14, reduce BLERTarget, otherwise execution in step 15 continues to judge sub-district present load rate situation.
Step 14: reduce BLERTarget.
When sub-district present load rate less than 20% the time, reduce BLERTarget;
The mode of reduction BLERTarget has a variety of, and enumerate dual mode in the present embodiment: a kind of is to carry out at the user, can be that the user is carried out one by one, or user grouping is carried out; A kind of is to carry out at business, can be that various types of business are carried out separately, as reducing the BLERTarget of data service or speech business, or various types of traffic packets is carried out;
Reduce BLERTarget and can adopt step-by-step system, the length of stepping is that step value can be determined and proofreaies and correct by modes such as emulation testings.
When reducing BLERTarget, the message transmission rate of data service, the speech quality of speech business or quality of services for users will inevitably improve, and therefore, can utilize the resource of sub-district more fully, as power resource.
Because the reduction of BLERTarget, the result of power control, the load of sub-district also will inevitably increase to some extent, and the added value of each cell load rate is with described step value and described to reduce the mode of BLERTarget at business or user relevant.
Step 15: whether judge sub-district present load rate greater than wealthy family's limit value, if greater than, then execution in step 16; Otherwise, return step 12, remeasure sub-district present load rate.
The load of sub-district is along with the reduction meeting of BLERTarget increases to some extent, but, in order to guarantee that the sub-district can provide service to new user, need the load factor of sub-district can not surpass certain standard, therefore, the cell load rate wealthy family limit value of sub-district present load rate and setting is compared, if greater than wealthy family's limit value, then execution in step 16, improve BLERTarget; Otherwise, BLERTarget is not adjusted, directly return step 12, remeasure sub-district present load rate, carry out the BLERTarget dynamic control process of following one-period.
Step 16: improve BLERTarget.
When sub-district present load rate is higher than 40%, improve BLERTarget;
The mode that improves BLERTarget is identical with the mode of described reduction BLERTarget, can be at the user one by one or grouping carry out, also can be separately or divide into groups to carry out at various types of business;
Improve BLERTarget and also can adopt step-by-step system, step value also can be determined and proofreaies and correct by modes such as emulation testings;
When improving BLERTarget, the message transmission rate of data service, the speech quality of speech business or quality of services for users will inevitably descend, owing to the result of power control, the load of sub-district also will inevitably decrease, so the sub-district can provide service to new user simultaneously.
The minimizing value of each cell load rate is with described step value and described to improve the mode of BLERTarget at business or user relevant.
The present invention is a loop control process, behind each reduction or the raising BLERTarget, system can return step 12 automatically, remeasures sub-district present load rate, and, carry out the BLERTarget dynamic control process of new one-period according to sub-district present load rate and described threshold value.
At the step 14 of certain data service, specify and reduce the beneficial effect that BLERTarget brings below in conjunction with embodiment of the present invention:
Such as when carrying out the 384kbps data service, if BLERTarget is set to 15%, so according to the result of external circule power control, this professional Mean Speed can only reach 384kbps * (1-15%)=326.4kbps.When sub-district present load rate during less than threshold ones 20%, can be by reducing this professional BLERTarget, message transmission rate is improved, such as BLERTarget is adjusted into 5%, speed that so should business will improve 384kbps * 10%=38.4kbps, and it is very considerable that speed promotes.
The present invention is preferably applied to the cell environment that the sub-district active user is less or load factor is lower.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
