Below lifting specific embodiment describes in detail to the present invention.
The present invention proposes a kind of method of automatic adjustment parcel detection threshold, predict the data service telephone traffic in next cycle by the telephone traffic of historical speech business and data service, and calculate the available PDCH number of data service in this cycle, to more effectively the desired value of parcel detection threshold is made to more excellent adjustment strategy.Below divide 3 aspects to introduce respectively.
Embodiment mono-:
For multicarrier equipment, gather voice-and-data business traffic data and the resource bearing efficiency index of each community as unit take community.Comprise:
Take 1 hour as unit collection traffic data, and be stored in server, server at least retains the traffic data of a week.Traffic data is mainly in order to judge and to predict speech business and the data service traffic situation of next hour each community, for the adjustment of parcel detection threshold provides foundation.
Gather the configuration of current channel resource and take situation take 1 hour as unit: comprise the configurable number of Traffic Channel in community (TCH) and take number, the configurable number of Static and dynamic PDCH and take number, for adding up available PDCH number of resources.
In the time of each end cycle, record available PDCH resource in this cycle, data service predicting telephone traffic and parcel prediction thresholding (in the present embodiment, parcel detection threshold comprises 3, thresholding A, thresholding B and thresholding C) mapping relations, and be stored in server, server at least retains the historical data mapping table of a week.Mapping table is mainly at the prerequisite making policy decision parcel thresholding of known available PDCH number, predicting telephone traffic historical data reference is provided.
The parameter format of this mapping table is as table 1:
Table 1
Gather resource bearing efficiency with 5 minutes or 15 minutes (depending on main equipment ability) granularities, for parcel detection threshold is done further adjustment and optimization provides foundation.Resource bearing efficiency is the data service flow of every PDCH channel unit interval carrying.
In the present embodiment, the concrete setting of data collection cycle is only for giving an example, and the present invention does not limit the concrete numerical value of data collection cycle.
Embodiment bis-:
In the time of this end cycle, predict data amount of data traffic and the available PDCH number in next cycle, and adjust the parcel detection threshold in next cycle according to predicting the outcome.
The first step, traffic forecast: go up respectively voice and the telephone traffic of data service of a hour and in history corresponding to the corresponding traffic data of this day identical period, in the time that both are suitable, judge that the traffic data of next hour is suitable with the traffic data of next hour of this day in history, and carry out analysis of strategies according to the traffic data of next hour of this day in history; In the time that both there are differences, according to difference between the two, by the traffic data of next hour of this day in history, the traffic data of next hour is predicted, and carried out analysis of strategies accordingly.
Second step, the statistics of available PDCH channel resource number:
According to the voice telephone traffic amount of next hour of prediction and the percent of call lost of expection, table look-up and estimate next hour required voice channel number, and according to the number of current TCH channel allocation, calculating speech business may need the dynamic PDCH number of channel of seizing, and is designated as M.For example, in the situation that the percent of call lost is 2%, expection voice telephone traffic amount is 30Erl, can learn that the TCH of speech business and the dynamic PDCH number of channel at least need 39 by inquiring about 2 tables.
Table 2
Calculate unappropriated PDCH quantity still, and next hour by the d/d PDCH number of channel, summation is designated as N.
Calculating the PDCH channel resource that next hour can take by data service is N-M.
The 3rd step, parcel thresholding decision-making: take available PDCH number of resources, data service predicting telephone traffic as parameter query mapping table.
If find available PDCH number of resources, the telephone traffic historical data entry corresponding with current prediction in mapping table, directly adjust parcel detection threshold A ~ C according to the threshold value in entry.If find many corresponding historical data entries, can adjust parcel detection threshold by the highest entry of load-carrying efficiency.Wherein, corresponding historical data entry refers to available PDCH number, the data service predicting telephone traffic entry similar to current prediction, judges whether that similar difference scope specifically sets according to actual conditions.
There are PDCH number of resources, the telephone traffic history entries similar to current prediction if do not find in mapping table, can estimate according to the amount of data traffic of prediction and available PDCH number of resources the resource bearing efficiency of next period, and according to the relation of the resource bearing efficiency of estimated expection and current resource bearing efficiency, adjust thresholding A ~ C that parcel detects, and after next hour finishes, the parcel detection threshold after adjusting is recorded in mapping table.Concrete method of adjustment is as follows:
If expection resource bearing efficiency is greater than current load-carrying efficiency (being the average discharge that in next unit interval period, the average discharge of PDCH is greater than the current period), the loads of data traffic that means next period can increase, should improve thresholding A ~ C, increase the data resource being responsible for assigning greatly; Otherwise, reduce thresholding A ~ C.In addition, thresholding A ~ C can synchronously adjust by step-length.The size of the each self-adjusting step-length of thresholding A ~ C can configure according to actual conditions.
The 4th step, PDCH resource is distributed: the relation of the parcel detection threshold A ~ C according to the length scale of packet and after adjusting is distributed PDCH resource, and distribution principle is as shown in table 3:
| The relation of the length L of packet and parcel detection threshold | The PDCH number of distributing |
| L < thresholding A | 1 |
| Thresholding A≤L < thresholding B | 2 |
| Thresholding B≤L < thresholding C | 3 |
| Thresholding C≤L | 4 |
Table 3
Embodiment tri-:
Adjust after parcel detection threshold, system, take 15 minutes as granularity, is monitored network performance according to the resource bearing efficiency data collecting.If resource bearing efficiency, lower than re-set target, is done further optimization by step-length to current parcel thresholding A ~ C, after optimization, do again the statistics of load-carrying efficiency, and make comparisons with the load-carrying efficiency of previous measurement period.Concrete mode is:
If the load-carrying efficiency after optimizing can increase step-length before being better than optimizing, continue parcel detection threshold to adjust according to adjusting direction last time; If the load-carrying efficiency after optimizing recovers last parcel detection threshold value before being inferior to optimization.
