Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Fig. 1 is the flow chart of definite method embodiment one of data traffic channels number of the present invention, and as shown in Figure 1, the method for present embodiment can comprise:
Step 101, obtain the corresponding relation between single time slot throughput, message transmission rate and the channel parameter of workload of data traffic channels.
Specifically, single time slot throughput is an important indicator in the present network operation, it can be used to represent the average transmission rate of sub-district individual channel, it can obtain divided by the transmission process time sum that all channels expend by all valid data transmission quantity sums of all channels in the measurement period, single time slot throughput is high more, the handling capacity of channel is fast more, and the byte number that each scheduling sends is also many more.For different single time slot throughputs, the message transmission rate of individual channel with the expression this channel operating efficiency the channel parameter of workload between corresponding relation also be different.In this step, can obtain the corresponding relation between different single time slot throughput, message transmission rate and the channel parameter of workload that obtains in advance.
In case obtain the corresponding relation between single time slot throughput, message transmission rate and the channel parameter of workload three, can determine single time slot throughput and the corresponding channel parameter of workload of desired data transfer with this sub-district according to this corresponding relation.Wherein, the desired data transfer of this sub-district can be provided with by operator, the size of single time slot throughput can be understandable that single time slot throughput of same sub-district is metastable often in the regular hour with reference to the traffic measurement data of this sub-district.
If the channel parameter of workload that is obtained represents that the live load of channel is bigger, it is just many more then to transmit the required data traffic channels number of the data volume of this data service, also promptly have only the more data traffic channels of configuration could satisfy desired message transmission rate, if the channel parameter of workload that definite device of data traffic channels number obtains represents that the live load of channel is less, it is just few more then to transmit the required data traffic channels data of the data volume of this data service, also promptly can satisfy desired message transmission rate in following less data traffic channels of needs of the less situation of channel load.The data volume of this data service also can be with reference to the traffic measurement data of this sub-district, for example the data volume of the data service of this sub-district in section sometime.
So far, can be configured processing to the data traffic channels in the sub-district, thereby optimize network configuration according to established data Traffic Channel number.
Present embodiment, before the data traffic channels to the sub-district is configured, can obtain the corresponding relation between single time slot throughput, message transmission rate and the channel parameter of workload three of data traffic channels of this sub-district, according to this corresponding relation, determine and the single time slot throughput and the corresponding channel parameter of workload of desired data transfer of this sub-district, can determine channel number comparatively accurately by this channel parameter of workload.By using this channel number the number of the data traffic channels of sub-district is configured, can be so that original configuration be simplified channel number more than the sub-district of estimated number, so that unnecessary high message transmission rate is lowered to the desired data transmission rate, the sub-district that also makes original configuration be less than estimated number increases channel number, gets a promotion so that be lower than the desired data transmission rate.Concerning whole network, can adopt the present embodiment method to calculate and handle the channel configuration of each sub-district, simplify the operation of discerning and attempt different parameters configuration data Traffic Channel number in the prior art at each sub-district, improved allocative efficiency greatly.
Another embodiment of the present invention provides definite method of another kind of data traffic channels number, specifically comprises:
At first, the business datum in the measurement period is carried out statistical disposition, obtain single time slot throughput, message transmission rate and channel parameter of workload in the measurement period;
Particularly, obtain the corresponding relation between single time slot throughput, message transmission rate and the channel parameter of workload three among the method embodiment one shown in Figure 1 by the method for network modelling.Need to prove that the corresponding relation that is generated both can be one group of corresponding relation, also can be many group corresponding relations.When the many groups of generation corresponding relation, every group of pairing single time slot throughput scope of corresponding relation can be different.
The embodiment of the invention is carried out single time slot throughput, message transmission rate and the channel parameter of workload that the required parameter of network modelling can comprise that measurement period is interior.Correspondingly, the process of this network modelling can be specially: the business datum in the measurement period is carried out statistical disposition, obtain single time slot throughput, message transmission rate and channel parameter of workload in the measurement period.
Secondly, according to single time slot throughput, message transmission rate and the channel parameter of workload of statistics, determine the corresponding relation between the three;
Further, can be that message transmission rate in same single time slot throughput scope and channel parameter of workload corresponding sample point are carried out process of fitting treatment, obtain and the corresponding matched curve corresponding relation of each single time slot throughput scope.
This modeling process can be specially:
1, at default network range, can be to arrive whole network greatly, also may diminish to a sub-district, or the scope that is provided with arbitrarily, extract the traffic measurement data of default measurement period, and count single time slot throughput, message transmission rate and the channel parameter of workload of each sub-district in each measurement period respectively, be understandable that this measurement period time also can be set arbitrarily.Can will be appreciated that the network range size of the accuracy of statistics and statistics and measurement period time length are directly proportional.
According to this method, promptly obtain a plurality of single time slot throughputs, message transmission rate and channel parameter of workload statistics, and form a tables of data.Promptly each element of this tables of data is the statistical value of the These parameters of each sub-district on each measurement period.
Further, this tables of data can be split as some groups according to single time slot throughput, and each group structure is identical, distinguishes to be affiliated single time slot throughput scope difference, for example, this list time slot throughput scope can be divided into above four groups of 0～25K, 25～35K, 35～45K and 45K.Therefore, the embodiment of the invention can be divided into four groups with the data in the tables of data according to this list time slot throughput scope.Need to prove that the span of single time slot throughput scope is adjustable, span is more little, and estimation will be accurate more, but the curve rate value of each scope differs also more little, and the meaning of differentiation also diminishes.In addition, the element number in some scope is very few, then can ignore or and adjacent scope merge, such as single time slot throughput seldom in the data of 0～15K, so 0～15K and 15～25K can be merged into 0～25K.In a word, the span of single time slot throughput scope can be according to the actual conditions adjustment of the traffic measurement data of network, and the embodiment of the invention does not limit it.
What 2, will obtain carries out the coordinate mapping with each single time slot throughput scope corresponding service data, thereby forms a sample point in the coordinate format of curve model.For instance, the Y-axis of this sample point can be the channel parameter of workload for message transmission rate, X-axis.The dot matrix of sample point will can be formed after all the business datum mappings in this list time slot throughput scope, for each single time slot throughput scope, its corresponding service data can form a slice dot matrix, and every dot matrix can constitute interior channel parameter of workload of certain single time slot throughput scope and the statistical relationship between the message transmission rate.All can carry out above-mentioned similar operations for the business datum in each single time slot throughput scope, thereby can obtain interior channel parameter of workload of each single time slot throughput scope and the statistical relationship between the message transmission rate, therefore, the quantity of the statistical relationship that is obtained is identical with the number of single time slot throughput scope of division.
Present embodiment is after the corresponding relation of having determined between the three, and follow-up step can be with reference to a last embodiment.
Be understandable that,, can carry out the process of fitting treatment of functional relation, thereby can obtain and the corresponding matched curve corresponding relation of each single time slot throughput scope the dot matrix of its corresponding sample point at each single time slot throughput scope.
Because for each sub-district, its single time slot throughput remains unchanged substantially, therefore, in the time need being configured to the channel number of a certain sub-district, can obtain the single time slot throughput of this sub-district and the channel parameter of workload of desired data transfer correspondence by this corresponding relation of inquiry.This channel parameter of workload can become the reference index when required channel data is configured, thereby can be this cell configuration quantity channel comparatively accurately.
Present embodiment is by the statistical history data, can determine the relation between single time slot throughput, message transmission rate and the channel parameter of workload statistics three accurately, thereby improved the accuracy of data traffic channels number, further improve resource utilization, simplify resource distribution, promote network performance.
Concrete, the message transmission rate that embodiment adopted in further embodiment of this invention can comprise a kind of in the following speed: logic link control (Logical Link Control, hereinafter to be referred as: LLC) (Radio Link Control is hereinafter to be referred as RLC) layer user's Weighted rate or rlc layer Mean Speed for layer user Weighted rate, LLC layer Mean Speed, Radio Link control.Wherein, LLC layer user Weighted rate can obtain by each secondary data business in the measurement period is weighted to handle in the transmission rate of LLC layer, and the weighted value of each time transmission be the byte number of this time transmission and the ratio that transmits total bytes.LLC layer Mean Speed is the total byte number of the inherent LLC layer transmission of measurement period and the ratio of the total duration of transmission.Rlc layer user Weighted rate can obtain by each secondary data business in the measurement period is weighted to handle in the transmission rate of rlc layer, and the weighted value of each time transmission be the byte number of this time transmission and the ratio that transmits total bytes.The rlc layer Mean Speed is the total byte number and the ratio that transmits total duration of measurement period in the rlc layer transmission.The difference of the message transmission rate of LLC layer and the message transmission rate of rlc layer is that at identical business datum, the speed of rlc layer can be slightly larger than the speed of LLC, but can both more accurately reflect and channel utilization between concern trend.
The difference of Weighted rate and Mean Speed is, the averaging method difference, and Weighted rate adopts average weighted mode, and Mean Speed then adopts complete average mode.For the different business of transmission rate, complete average method reflects the influence of their speed difference for overall rate more accurately not as weighted-average method.The truth of more pressing close to network with the weighted-average method rate calculated, thus more accurate, but the two is consistent in reflection with concerning on the trend of channel parameter of workload.
Optionally, the channel parameter of workload that the embodiment of the invention adopted can comprise: channel utilization or channel seizure ratio.Wherein, channel utilization is valid data piece number that transmits on the data traffic channels and the ratio of dispatching total block data.Channel seizure ratio is a data block transmitted number and the ratio of dispatching total block data on the data traffic channels.
Hence one can see that, the difference of channel seizure ratio and channel utilization is, channel utilization adopts the valid data piece number that transmits on the data traffic channels as molecule, the data block transmitted number is as molecule on the channel seizure ratio employing data traffic channels, and the data block transmitted number will be more than the valid data piece number of transmission, because the data block transmitted number also comprises redundant blocks such as re-transmission, but the reflection and channel utilization concern on the trend that the two is consistent.
Fig. 2 is the flow chart of definite method embodiment two of data traffic channels number of the present invention, in this embodiment, the channel parameter of workload is a channel utilization, channel utilization is valid data piece number that transmits on the data traffic channels and the ratio of dispatching total block data, and the data volume of data service is that the valid data piece on the data traffic channels is counted estimated value.As shown in Figure 2, the method for present embodiment can comprise:

For instance, present embodiment is that example describes with the corresponding relation between single time slot throughput, LLC layer user's Weighted rate and the channel utilization three.
Specifically, when determining to be configured the channel number of certain or some sub-districts, can determine single time slot throughput of this sub-district, this list time slot throughput can obtain by the traffic measurement data of this sub-district are carried out statistical analysis.For each sub-district, its single time slot throughput is constant substantially.After obtaining single time slot throughput of this sub-district, can determine single time slot throughput scope at single time slot throughput place of this sub-district.
After single time slot throughput scope of determining this sub-district correspondence, can determine the corresponding relation between LLC layer user's Weighted rate and the channel utilization.
Be understandable that what adopt when message transmission rate is one of other several parameters, can implement equally.
Fig. 3 is the employed a kind of network model curve synoptic diagram of the embodiment of the invention shown in Figure 2, as shown in Figure 3, exemplarily shows four curves in this network model curve, every curve promptly corresponding a single time slot throughput scope.For instance, each single time slot throughput scope is respectively 0～25K, 25～35K, 35～45K and more than the 45K, its corresponding respectively curve 1～4.The longitudinal axis shown in Figure 3 can be represented LLC layer user Weighted rate for instance, and transverse axis can be channel utilization for instance.Single as shown in Figure 3 time slot throughput is high more, and the handling capacity of channel is fast more, and the byte number that each scheduling sends is also many more.
Therefore, in the time of can determining that according to single time slot throughput of sub-district channel number to this sub-district is configured, the curve of its required use, one of four curves for example shown in Figure 3.For instance, if single time slot throughput of this sub-district is 38K, then single time slot throughput of this sub-district is promptly in this single time slot throughput scope of 35～45K, when the channel number of sub-district is configured, the curve of its required use is and the corresponding curve of this single time slot throughput scope of 25～35K, and promptly curve 3.
With above-mentioned Fig. 3 for instance, after definite required model curve that uses is as curve 3, can determine on this curve 3 and the corresponding channel utilization of expection LLC layer user's Weighted rate.For instance, if expection LLC layer user Weighted rate is 100K, then can be by inquiry curve 3, obtaining the channel utilization corresponding with 100K is 0.17.
Wherein, channel utilization is valid data piece number that transmits on the data traffic channels and the ratio of dispatching total block data, and this valid data piece is counted estimated value and can be obtained by the traffic statistics is carried out statistical disposition.
