Voice service load generation module 303, voice service statistical characteristic analysis module 304, reciprocity speech load output module 305.
It is assumed that in the case of known to Signal to Interference plus Noise Ratio, voice service load control module 301 is anti-according to the first equity fitting
First degree of fitting coefficient of the feedback feedback of control module 302, arrival rate λ and service rate μ is adjusted with predetermined step.Voice service is born
Generation module 303 is carried according to arrival rate λ and service rate μ generation simulated voice business loads.Voice service statistical characteristic analysis mould
Test data after the simulated voice business load of 304 pairs of generations of block and the division carries out statistical analysis, draws simulated voice
The PDF of business load（Probability density function）Curve, calculates the average and variance of the PDF curves, and the PDF curves are reflected
Voice service load statistics characteristic output to first equity fitting feedback control module 302.First equity fitting feedback control
The load of voice service that module 302 pairs is measured and the simulated voice business load degree of being fitted analysis, to obtain described the
One degree of fitting coefficient, and when the first degree of fitting coefficient exceedes default thresholding, control the reciprocity speech load defeated
Go out the simulated voice load of module output and the speech load equity of the proximal segment, stage casing and distal section region of cell, while will

The simulated voice business load of voice service load equities of the whole arrival rate λ and service rate μ to generate and measure, can make
Obtain the voice service load that can be preferably converged to after a few wheel feedback cycles are experienced and measured.
Here is schematic illustration of the voice service load control module 301 to the control of arrival rate λ and service rate μ.
It is determined that in the case of relevant parameter, the load that cell voice service is produced only is determined by arrival rate λ and service rate μ
It is fixed, and the effect of increase arrival rate λ and reduction service rate μ is of equal value, that is to say, that the load that cell voice service is produced is only
Determined by the ratio of arrival rate λ and service rate μ.Voice service load control module in voice service load peer device 300
301 can control remotely to initiate session, and session has the regular hour to constrain every time, that is to say, that voice service load control mould

Density profile is determined by arrival rate λ and service rate μ.Adjustment arrival rate λ and service rate μ, such that it is able to realize voice service
Equity on probability density distribution.
In order to analyze more to correspond to reality, the influence interference to cell load is taken into account.It is assumed that descending many at one
Cell communication systems include M base station and K user.Resource is divided in time domain and frequency domain simultaneously.On frequency domain, entirely
Communication bandwidth is divided into m sub-channels, and each channel occupies corresponding bandwidth.So cell can be equivalent to one
M/M/m queuing systems, it is considered to which it is the Poisson distribution of λ that the generation process of user obeys parameter, service time interval obeys iid parameters
It is the quantum condition entropy of μ, while be up to m user can receive service, in the case where system tends to balance stabilization, can obtains
To this section of region of cell（Such as proximal segment region）In average user number be：WhereinIt is resistance
Plug probability.Generally think that the proportion shared by real-time traffic users number is γ=0.5, i.e. real-time traffic users number N1=
0.5N, in the case of given blocking probability, average user number and power system capacity m, arrival rate of customers λ in every section of cell, clothes
μ is relevant for business rate.If the transmission power of base station j is P, then the Signal to Interference plus Noise Ratio that user k is received in time slot t（SINR）ForWherein, Z represents white Gaussian noise, Gj,kT () represents that the channel between base station j and user k increases
Benefit.Assuming that SINR keeps constant in time slot t, then the speed shannon formula of user k can be expressed as：rj,k(t)=BJ, mlog2
(1+SINRj,k(t)), Bj,kIt is represented to belong to the bandwidth of the user k distribution of base station j.In view of community user on distance and position
Difference, it will be assumed that：P0It is the transmit power of cell distal section user, α P0It is the transmit power of cell stage casing user, β P0It is cell
The transmit power of proximal segment user, wherein 0<α<1,0 ＜ β<1, and α>β.
So, cell distal section user k1The Signal to Interference plus Noise Ratio received in time slot t is：
Cell stage casing user k2The Signal to Interference plus Noise Ratio received in time slot t is：
Cell proximal segment user k3The Signal to Interference plus Noise Ratio received in time slot t is：
From the statistical significance, for LTE system, it is by the Mean Speed of voice serviceThen cell is respectively obtained remote
The quantity of the average RB blocks that the user of section, stage casing and proximal segment takes in time slot t is respectively：
Distal section：
Stage casing：
Proximal segment：
Now, the voice service in cell in different sections is can obtain to be respectively in the load that time slot t is produced：
Distal section is loaded：ηt1=N1m1/ N,
Stage casing loads：ηt2=N2m2/ N,
Proximal segment is loaded：ηt3=N3m3/ N,
Wherein WRBIt is the bandwidth shared by a RB block, N is the whole RB blocks of system, m1、m2、m3Respectively cell distal section, in
The voice service number of users of section and proximal segment.In the case where the Signal to Interference plus Noise Ratio SINR of user is certain, η can be respectively depictedt1、
ηt2、ηt3With the curve that t changes, η is further depicted as outt1、ηt2、ηt3Probability density function.
For cdma system, load is then the ratio of the code channel number shared by user and total code channel, the analysis mode of its load
It is similar to above, thus repeat no more.
After the probability density function of the voice service of proximal segment, stage casing and distal section in cell realizes equity, in order that
The probability density function of total load also realizes equity, it is necessary to go to adjust the load of data service again.According to the characteristic of data service,
Data service uses a kind of mechanism for ensureing primary bandwidth demand, maximum bandwidth demand being ensured with remaining bandwidth, total load
Equity just only need to adjust data service generation.

Load equity.Data service and the difference of voice service are that data service allows certain time delay during transmission.
Different types of data service model is different, and model parameter number and distribution are also different, but in the load equity of cell,
The behavioural characteristic of the statistics of these data services is described with handling capacity, i.e. the data bit value of transmitted per unit time.Root
Setting up emulation according to business model can obtain the curve that handling capacity is changed over time, and then can depict the probability of data service
The parameter such as density function and average and variance.Due to portraying different data services（HTTP business, ftp business etc.）The ginseng of model
Number is different, and the key parameter of such as ftp business is file size（Obey truncation logarithm normal distribution）, reading time（Obey
Exponential distribution）, session arrival interval（Obey Poisson distribution）, number of files（Obey geometry distribution）；The crucial ginseng of HTTP business
Number is session arrival interval（Obey Poisson distribution）, the packet number in a packet call（Obey geometry distribution）, once can
Page number in words（Obey geometry distribution）, reading time（Obey exponential distribution）Deng.It will be apparent that these parameters are directly determined
The load of correspondence business.Because data service uses a kind of remaining bandwidth using mechanism.Thus born in completion voice service
After the equity of load, in order to realize the equity of total load, the generation of data service need to be only adjusted.Due to different data services
Portray that model is different, the key parameter of various models is also different, and obeys different distributions, such as influence these data services
The major parameter of load capacity has：Session reaches interval, and file size is grouped number.Data service generation module is by adjusting meeting
Words reach interval, and file size, the average and variance for being grouped number controls the load capacity and all data of different pieces of information business
The data volume of business realizes the equity of total load.
