Specific embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
The present invention provides a kind of up-link carrier polymerization maintaining method, polymerize maintaining method first embodiment in up-link carrier
In, referring to Fig.1, the up-link carrier polymerization maintaining method includes:
Step S10, bias and bias when secondary carrier when base station obtains main carrier；
Existing up-link carrier polymerization technique is to allow multiple cells can be for 1 terminal service, and the cell of terminal access
It is defined as main carrier, multiple secondary carriers are added to terminal by reconfiguration after access.The uplink sync status of main carrier and secondary carrier
All safeguarded by main Timing Advance group.And main carrier and secondary carrier be during providing data and business uplink, base station
It can bias and bias when secondary carrier when getting corresponding main carrier according to the uplink state of main carrier and secondary carrier.Due to reality
In arranging net, main carrier and secondary carrier the case where there may be non-with covering, therefore, bias and bias can when secondary carrier when main carrier
Energy is simultaneously asynchronous, will cause uplink communication penalty in this way, communication quality is caused to reduce.Therefore base station is needed according to main carrier
When the bias and actual conditions of bias are specifically adjusted when secondary carrier.
Step S20, bias and bias carries out digital filtering processing when secondary carrier when base station is to main carrier, to obtain main carrier
Filter value and secondary carrier filter value；
In reality scene, bias and bias can be because of environment or hard when secondary carrier when main carrier accessed by base station
There is certain fluctuation up and down in the reasons such as part, including signal interference or signal receive it is bad.And this unconventional error pair
The function course of base station and terminal adjustment time lead to be adjusted can generate large effect, i.e. reference number during the adjustment
According to inaccuracy influence whether the accuracy of adjusting parameter.Therefore base station firstly the need of to accessed main carrier when bias and negative
Bias is filtered screening when carrier wave.In the present embodiment, bias when bias when main carrier and secondary carrier is carried out number by base station
Filtering algorithm filtering,
Specifically, one of median filtering algorithm, limit filtration algorithm and first-order lag filtering algorithm can be used in base station
Or it is several, bias and bias carries out data filtering when secondary carrier when to main carrier cleans bias when discrete carrier wave,
Rejecting abnormalities measured value, so that bias and bias when secondary carrier when obtaining stable main carrier, are respectively set to main carrier
Filter value and secondary carrier filter value, for subsequent calls.
Step S30, base station are weighted main carrier filter value and secondary carrier filter value, input partially when obtaining
Value；
Base station gets main carrier filter value and secondary carrier filter value, that is, gets stable main carrier filter value and auxiliary load
Wave filter value, thus ensure it is subsequent adjustment main carrier and secondary carrier when partially adjust during adjust data stability and reference
Property.And base station needs to calculate the adjustment pair got in up-link carrier polymerization according to main carrier filter value and secondary carrier filter value
As and adjusted value.That is, base station needs are pointedly real according to current main carrier and the actual operating state of secondary carrier
Apply plan for adjustment.Therefore in the present embodiment, the method that base station uses weighted calculation filters main carrier filter value and secondary carrier
Value is weighted, i.e., presets corresponding weighted factor according to the communication condition of main carrier and secondary carrier, carries out logic calculation,
To obtain the when inclined input value of the main Timing Advance group of adjustment main carrier and secondary carrier.
When described inclined input value refer to adjustment main carrier and secondary carrier uplink sync status maintenance parameters, according to when it is inclined
Input value, base station and terminal to be adjusted can completely coordinate and manage the uplink sync status in upstream data channel,
To avoid main carrier and secondary carrier from deviating normal transmission frame road in uplink state, and then influence the synchronization shape of up-link carrier
State.
Specifically, it can be refined referring to Fig. 2, the step S30 are as follows:
Step S31, base station obtain the first uplink mistake packet number of main carrier and the second uplink mistake packet number of secondary carrier；
Base station carries out assigning each filter value corresponding to the weighted calculation of main carrier filter value and secondary carrier filter value
Weighted factor.In the present embodiment, the Variable Factors of uplink mistake packet number are introduced.The uplink mistake packet number refers to each up-link carrier
In the transmission process for realizing communication data, the data packet packet loss or data packet occurred receives abnormal transmission abnormality shape
Condition.And this transmission abnormality state can be recorded in the signal connection of terminal to be adjusted and base station, for example, to be adjusted
Terminal sends data packets to base station, and base station does not receive after the upload request for getting terminal to be adjusted wait adjust
Data packet Transmission occurs in the data packet for receiving upload for the data packet or base station that whole terminal uploads, and leads to data
When packet receives phenomena such as imperfect, by the data packet for the loss that this is not received and incomplete packet data recording can be received
Get off.
Since terminal to be adjusted is provided with the function of data packet transmission in main carrier and the data transmission channel of secondary carrier,
Therefore the second uplink mistake packet number of base station recordable the first uplink mistake packet number for getting main carrier and secondary carrier.First uplink is wrong
Packet number and the second uplink mistake packet number can be used as the references object of the weighted factor of main carrier filter value and secondary carrier filter value.
Step S32, base station are based on the first uplink mistake packet number and the second uplink mistake packet number, determine the first weight of main carrier because
Second weight factor of son and secondary carrier；
In the database of base station, it is preset with and the first mutual corresponding first weight factor of uplink mistake packet number, Yi Jiyu
Second mutual corresponding second weight factor of uplink mistake packet number.That is the uplink mistake bag data of up-link carrier is respectively mapped with respective
Weight factor, also, even if uplink mistake packet number is consistent, the weight factor of different carrier waves may also be different.In the present embodiment
In, uplink mistake packet number is more, then corresponding weight factor can also accordingly increase.
Step S33, base station are based on main carrier filter value, secondary carrier filter value, the first weight factor and the second weight factor
It is weighted, inclined input value when obtaining.
After getting the first weight factor and the second weight factor, base station can be according to main carrier filter value, secondary carrier
Filter value, the first weight factor and the second weight factor carry out logical operation, inclined input value when obtaining specific.
Assuming that using two carrier wave of uplink as background, if a is the second weight factor of secondary carrier filter value,
If main carrier filter value is TimeOffsetSmoothpcc, secondary carrier filter value is TimeOffsetSmoothScc,,
And when inclined input value be set as TimeOffsetpTag, then according to specific base station weight computation method, above data is substituted into following
Formula:
TimeOffsetpTag=(1-a) * TimeOffsetSmoothpcc+a*TimeOffsetSmoothSCC
If a use 0.5, then it represents that the first weight factor and the second weight of main carrier filter value and secondary carrier filter value because
Son is 0.5, meanwhile, substitute into formula, inclined input value when can be obtained.
Step S40 when the absolute value of inclined input value is greater than first threshold when base station detects, obtains data control and refers to
It enables, and DC instruction is sent to terminal to be adjusted, so that terminal to be adjusted carries out the same step of subcarrier time lead
It is whole.
When base station is got after inclined input value, the size of inclined input value when can determine that, to be under judging present case
The no Timing Advance for needing to adjust main carrier and secondary carrier.Specifically, a first threshold has been preset in base station
TimeOffsetThr, base station judge the size between the absolute value of TimeOffsetpTag and TimeOffsetThr, if |
TimeOffsetpTag| > TimeOffsetThr then proves that up-link carrier needs are adjusted, and base station will issue number according to agreement
According to control instruction (i.e. TAC MACCE, Timing Advance Command MAC Control Element), adjust to be adjusted
The subcarrier time lead of terminal pTag, to keep uplink to be in synchronous regime；Otherwise, it ends processing.
Specifically, the step of obtaining DC instruction in reference Fig. 3, step S40 can refine are as follows:
Step S41, base station is based on main carrier filter value and first threshold is calculated, to obtain main carrier adjusted value；
Step S42, base station is based on secondary carrier filter value and first threshold is calculated, to obtain secondary carrier adjusted value；
Main carrier filter value TimeOffsetSmoothpccLogic calculation, example are carried out with first threshold TimeOffsetThr
Such as TimeOffsetSmoothpcc- TimeOffsetThr, acquisition main carrier adjusted value, and secondary carrier filter value
TimeOffsetSmoothsccLogic calculation, such as TimeOffsetSmooth are carried out with first threshold TimeOffsetThrscc-
TimeOffsetThr obtains secondary carrier adjusted value.
It is understood that being that this is based on terminal master to be adjusted representated by main carrier filter value and secondary carrier filter value
The synchronous adjustment value of carrier wave and the synchronous adjustment value of secondary carrier.It is mainly used for the synchronous coordination to subcarrier time lead.
Step S43, base station is based on main carrier adjusted value and secondary carrier adjusted value generates DC instruction.
The DC instruction is with the concrete mode of adjustment needed for represent terminal to be adjusted.Wherein, it is controlled in data
The 6th bit in instruction can indicate main carrier adjusted value and secondary carrier adjusted value with 0 to 63, i.e. base station is by DC instruction
After being sent to terminal to be adjusted, terminal can analyze the 6th bit in DC instruction, to get specific main load
The 6th bit of wave adjusted value and secondary carrier adjusted value, i.e. base station time in DC instruction has determined specific adjustment
The adjustment mode (in advance or delaying) of object (main carrier and secondary carrier) and specific Timing Advance.
It should be noted that laboratory and outfield are verified, and before taking this scheme, the uplink two of 20MHz+20MHz
Carrier wave main carrier and secondary carrier when differing 40Ts partially, secondary carrier flow-reduction is that theory is flow 20%；Using this scheme
Afterwards, main carrier and secondary carrier flow can reach 95% or more of theoretical flow.
The present invention passes through bias when bias when the acquisition main carrier of base station and secondary carrier；Bias and auxiliary load when base station is to main carrier
Bias carries out digital filtering processing when wave, to obtain main carrier filter value and secondary carrier filter value；Base station is to main carrier filter value
It is weighted with secondary carrier filter value, inclined input value when obtaining；When base station detects, the absolute value of inclined input value is big
When first threshold, DC instruction is obtained, and DC instruction is sent to terminal to be adjusted, for terminal to be adjusted
Carry out the synchronous adjustment of subcarrier time lead.The present invention, which realizes, solves main carrier and secondary carrier not exclusively arranging net with covering
The technical issues of up-link carrier synchronizes uncoordinated under scene, and communication quality is caused to reduce makes communication quality obtain optimal mention
It rises, reduces operator and arrange net difficulty of construction, improve the communication quality of up-link carrier polymerization.
Further, on the basis of up-link carrier of the present invention polymerize maintaining method first embodiment, up-link carrier is proposed
It polymerize maintaining method second embodiment, the difference between the second embodiment and first embodiment is, the base station obtains
Secondary carrier when bias quantity be one or more.
In the present embodiment, due to the quantity more than one of terminal to be adjusted, then bias when the main carrier that base station is got
One is more than with bias when secondary carrier.And certain difference can be also generated for the weighted calculation mode of multiple secondary carriers,
The technical principle of implementation does not change, but calculation changes.
In multiple secondary carriers that base station is got in the case of bias, the present embodiment inclined input value when calculating
TimeOffsetpTagCalculation formula it is as follows:
Assuming that n 2, a1 is initially set to 0.2, a2 and is initially set to 0.2 using three carrier wave of uplink as background,
TimeOffsetThr is set as 6Ts, and implementation is described as follows:
1, bias is denoted as TimeOffset when base station measurement obtains main carrier, secondary carrier 1, secondary carrier 2pcc、
TimeOffsetscc1And TimeOffsetscc2。
2, bias carries out digital filtering when base station obtains measurement, and bias is remembered when stable main carrier after accordingly being filtered
For TimeOffsetSmoothpcc, secondary carrier when bias TimeOffsetSmoothscc1With bias when secondary carrier
TimeOffsetSmoothscc2。
3, base station calculates the when inclined input value TimeOffsetpTag of pTag, and formula is as follows:
TimeOffsetpTag=(1-a1-a2) * TimeOffsetSmoothpcc+a1*TimeOffsetSmoothSCC1+
a2*TimeOffsetSmoothSCC2
Base station can adjust the value of ai according to the uplink mistake packet number dynamic of secondary carrier i, and specific method is secondary carrier i uplink mistake packet
Number increases, then increases ai value；Increase if main carrier uplink misrepresents deliberately number, reduces all ai values, increase the weight of main carrier.
4, base station judges | TimeOffsetpTag| > TA adjusts thresholding TimeOffsetThr, then issues TAC according to agreement
MACCE (Timing Advance Command MAC Control Element, time advance order MAC Control Element) is adjusted
The TA of whole terminal pTag keeps uplink to be in synchronous regime；Otherwise, it ends processing.
The present invention also provides a kind of up-link carriers to polymerize maintaining method, polymerize maintaining method 3rd embodiment in up-link carrier
In, the up-link carrier polymerization maintaining method includes:
