Embodiment
In order that those skilled in the art more fully understand the technical scheme in the embodiment of the present invention, and make of the invention real Apply the above-mentioned purpose of example, feature and advantage can be more obvious understandable, below in conjunction with the accompanying drawings to technical side in the embodiment of the present invention Case is described in further detail.
It is a kind of flow chart of base station collocation method of the embodiment of the present invention referring to Fig. 1.
Using telegon as executive agent, this method can include the present embodiment：
Step 101, telegon carries out base station sub-clustering to determine at least one cell cluster.
In this step, telegon can be according to the cluster-dividing method pre-set；Or according to the neighboring BS information of base station to more Individual base station divides cluster；Can also be the first kind base station in multiple base stations, the base station that capacity and covering problem such as be present （The capacity of the first kind base station is unbalanced with covering）, multiple base stations are divided, specifically refer to subsequent embodiment Description.Multiple base stations can be divided into several cell clusters by the telegon, wherein can be included in each cell cluster at least one Base station.Neighboring BS information can be that adjacent area identifies, and can be identified according to the adjacent area of the first kind base station, by the first kind base station In adjacent multiple base stations be divided into a small district's groups.
Step 102, the telegon sends the antenna configuration parameters of all base stations in the cell cluster to the cell Each base station of cluster, so that each base station of the cell cluster is respectively according to the antenna configuration parameters meter of all base stations in the cell cluster Calculate respective utility function value and determine the antenna configuration parameters of each self refresh.Utility function is similar to object function, main to use Carry out the reasonability and advance of evaluation algorithms.In the present embodiment according to the utility function of antenna configuration parameters that is evaluation day Line utilizes rational object function, it is believed that is how to evaluate the rational function of antenna parameter configuration.
Telegon sends the antenna configuration parameters of all base stations in each cell cluster to this after cell cluster has been divided Each base station of cell cluster.Wherein, the antenna configuration parameters of all base stations can report telegon by each base station, or What telegon prestored.The antenna configuration parameters can be specifically the transmission power of base station, or the transmission power of base station And Downtilt.In addition, telegon can use man-to-man mode transmission antenna configuration parameter, for example, telegon is transferred The antenna configuration parameters of all base stations of cell cluster, are then forwarded to certain base station where certain base station；Can also be using broadcast Mode, such as cell cluster in advance by dividing cell clusters obtain cell cluster information broadcast to each base station, in the cell cluster information Mark of base station etc. in the mark and each cell cluster of each cell cluster can be included, each base station would know that according to the cell cluster information Cell cluster where itself, telegon by way of broadcast by the antenna configuration parameters of all base stations of each cell cluster send to During each base station, base station can be according to predetermined cell cluster where itself, all base stations of cell cluster where obtaining it Antenna configuration parameters.After the antenna configuration parameters of all base stations of cell cluster where knowing of each base station, i.e., using the cell cluster The antenna configuration parameters of all base stations, call utility function to be calculated, obtain utility function value and determine the base station more New antenna configuration parameters, the utility function value show the performance indications of base station.Each base station will obtain respective utility function value And the antenna configuration of renewal is sent to telegon.
Step 103, the telegon receive the respective utility function value that each base station of the cell cluster sends and The antenna configuration parameters of each self refresh.
Step 104, when the difference between maxima and minima in the utility function value of each base station in the cell cluster is big When threshold value, the telegon sends the antenna configuration parameters that all base stations of the cell cluster update each to the cell cluster Base station, so that antenna configuration parameters of each base station of the cell cluster according to the renewal of all base stations of the cell cluster, iteration meter Calculate the utility function, until in the cell cluster that receives of the telegon in the utility function value of each base station maximum with Difference between minimum value is less than or equal to the threshold value.
Telegon calculates the difference of the utility function value between each base station in cell cluster, when the difference is more than default function When being worth threshold value, then the renewal antenna configuration parameters of each base station of the cell cluster are sent to each base station of the cell cluster, each base station profit Iterate to calculate utility function value with the antenna configuration parameters of the renewals of all base stations of the cell cluster, until telegon receive it is same The difference of utility function value in one cell cluster between each base station is less than or equal to functional value threshold value, and now, iteration is completed.
Step 105, the telegon according to the result of the iterative calculation determine each base station of the cell cluster most from morning till night Line configuration parameter.
Telegon is after the completion of the utility function iterative calculation of each cell cluster base station, you can last time is iterated to calculate into institute The antenna configuration parameters of the renewal of each base station used are defined as the configuration parameter of the base station of each cell cluster.Base in each cell cluster The utility function value obtained by the above method of standing result after iteration reaches unanimity, so as to find each of network optimum The configuration parameter of base station, so as to optimize the equilibrium between the covering of the whole network and capacity.
Step 106, the telegon sends the final antenna configuration parameters of each base station of the cell cluster of determination to institute Each base station of cell cluster is stated, so that each base station of the cell cluster is configured.
Multiple base stations are divided into cell cluster by telegon in the embodiment of the present invention, and using distributed mode by each cell The base station of cluster each iterates to calculate utility function, and then telegon obtains base station utility function value in each cell cluster and reached unanimity Iteration result, so as to obtain the configuration parameter of each base station of network optimum, improve between the covering of the whole network and capacity It is balanced.
In another embodiment of the invention, as shown in Fig. 2 the side that multiple base stations are divided at least one cell cluster Method can include：
Step 201, the neighboring BS information that the first kind base station in multiple base stations reports is received.
First kind base station can count its adjacent zone information reporting to telegon.Wherein, the first kind base station refers to that network is deposited In the base station of capacity and covering problem.
Step 202, according to first kind base station and its neighboring BS information, first kind base station is divided at least one small district's groups.
Telegon is grouped to the first kind base station in network according to adjacency.The neighbour reported according to each first kind base station Base station information is occupied, if multiple adjacent first kind base stations be present（Adjacent multiple base stations in first kind base station）, then these first Class base station is divided into one group；If not having adjacency between first kind base station, each first kind base station itself turns into one group.
Step 203, the neighbor base station of small district's groups and small district's groups is merged into cell cluster.
Telegon is further handled the small district's groups after sub-step 202, by the neighbour of a small district's groups and the small district's groups Area base station is combined, and is divided into a cell cluster.If having common adjacent area between multiple small district's groups, these small district's groups and adjacent area Base station is combined, and is divided into a cell cluster.
Wherein, in another embodiment, as shown in figure 3, base station determines whether its own is that the method for first kind base station can With including：
Step 301, base station obtains its network state parameters, and the network state parameters can refer to including network state performance Mark.
Base station such as can report to obtain the network state parameters of itself at the approach by base station measurement and terminal, such as characterize base The performance indications for current network state of standing（KPI, such as cell throughout, call blocking rate, Call outage probability）, the network state Parameter can also also include network metric（NV, such as community user number）And control parameter（CP, such as base station transmitting power, antenna Angle of declination, handoff parameter etc.）.
Step 302, base station contrast network state performance indications with the sub-clustering database that previously generates each cluster it is network-like State performance indications, to determine a cluster that whether network state of the base station belongs in sub-clustering database.
Before this step, sub-clustering database is firstly generated, the network state of each cluster can be included in the sub-clustering database Performance indications and it is corresponding the problem of use-case.The sub-clustering database is according to caused by priori, can be based on expert system Expert instruct knowledge to produce, or based on network it is conventional the problem of optimum results produce.Wherein, the problem of corresponding to use-case is special Family's system the provides or network problem is in the CROSS REFERENCE for having occurred and that and successfully optimizing before.
The sub-clustering database can be that the base station obtains network state sampled value by periodic sampling, and these sampled values are used for Produce network state sub-clustering database.Meanwhile each network state sampled value is converted into a principal component by principal component analysis Vector data, the i.e. corresponding network state sampled value of a principal component vector data.Specifically, the sub-clustering database can be as Shown in following table：
Wherein what first row stored is the cluster heart of each cluster, specifically can show one using principal component vector data as mark Individual cluster is centered on the cluster heart.What secondary series stored is the network state property corresponding to the cluster, is represented safely corresponding to the cluster Each KPI performances of network meet the requirement of operator, i.e. network is in a safe condition, otherwise map network produced problem Use-case.3rd row storage is the mould for characterizing the cluster, and each mould is characterized by NV and the tuples of CP two；The number for the mould that each cluster contains It is not necessarily identical.4th row storage is each corresponding to cluster at sampling in the network state sub-clustering database for generating What reason obtained belongs to principal component vector corresponding to each network state of the cluster（PCV）；PCV numbers depend on corresponding to each cluster Sample the number of the heterogeneous networks state for belonging to the cluster obtained.It was found from the 3rd row and the 4th row, a cluster includes multiple Network state sampled value, each network state are characterized with a principal component vector data, while one PCV pairs in the 4th row Answer one or more of the 3rd row two tuples pair（NV,CP）, each（NV,CP）To being referred to as a mould, therefore a sub-clustering Corresponding multiple moulds.
After above-mentioned sub-clustering database is obtained, in this step, base station contrasts network state performance indications with previously generating Sub-clustering database in each cluster network state performance indications, to determine whether the network state of the base station belongs to sub-clustering database In a cluster.As shown in figure 4, the step can further comprise again：
Step 401, analysis obtains the principal component vector of the network state performance indications of the base station, is sweared as first principal component Amount.
Base station based on sampling obtain KPI value, carry out principal component analysis, pick out can mainly characterize KPI data it is main into Resolute PCV.Then sub-clustering processing is carried out for existing network state sub-clustering database to PCV data.
Wherein, can be by reluctant high-dimensional KPI data by the process of KPI value analysis acquisition principal component vector Dimensionality reduction is to only accessible low dimensional（Less several dimensions）PC characterize, each PC is all KPI linear combination, and And between each PC be linear independence, the PC of the low dimensional is the principal component vector PCV for forming KPI.By principal component analysis, The PC of a small amount of several dimensions is only needed to characterize high-dimensional network state, so as to substantially reduce the complexity of data processing. The process that pcv value is specifically obtained by KPI value may refer to the entitled network state division methods based on MANET SON, dress Put and network system, the patent of Application No. 201210382146.8.
Step 402, the membership probability between first principal component vector and Second principal component, vector is calculated, obtains greatest member Probability, wherein, Second principal component, vector is the principal component of the network state performance indications of each cluster cluster heart in the sub-clustering database Vector.
For the ease of description, by the representative network state performance index of the cluster heart of each cluster in sub-clustering database, namely each cluster KPI principal component vector（PCV）, it is designated as Second principal component, vector.The dimension of the Second principal component, vector is sweared with first principal component The dimension of amount is identical.
Obtaining the data PCV of sign current base station network stateiAfterwards, the PCV is calculatediWith each cluster heart in sub-clustering database PCVjBetween membership probability UI, j, wherein greatest member's probability is designated as MaxUi,j。
Calculating membership probability UI, jMethod can be computational representation current base station network state data PCViTo each cluster The PCV of the heartjThe distance between.The specific method for calculating membership probability may refer to the entitled network based on MANET SON State demarcation method, apparatus and network system, the patent of Application No. 201210382146.8.
Step 403, if greatest member's probability is more than or equal to probability threshold value, the network state of base station belongs to the sub-clustering number According to the cluster where Second principal component, vector corresponding with greatest member's probability in storehouse；If greatest member's probability is less than probability Threshold value, then the network state of base station be not belonging to the either cluster in sub-clustering database.
Find greatest member's probability MaxU in sub-clustering databasei,jCorresponding cluster, if MaxUi,jMore than default probability threshold value During THu, then it is assumed that the network state of current base station can be included in greatest member's probability MaxU in sub-clustering databasei,jCorresponding cluster, it is no Any one cluster of existing database can not be included in by then thinking the network state of base station.
Wherein, the setting of the probability threshold value can be set by operator according to artificial experience, and such as 0.6.
After in base station, execution step 302 determines whether the network state of the base station belongs in sub-clustering database cluster, If the cluster belonged in sub-clustering database, step 303 is performed, if a cluster being not belonging in sub-clustering database, is performed Step 304.
Step 303, use-case is net when the cluster belonging to the network state of the base station is corresponding in sub-clustering database the problem of When network is covered with capacity problem, it is first kind base station to determine the base station.
If the network state of base station can be included in a cluster of existing network state sub-clustering database, show the net of base station Network state is known, if current base station network goes wrong, the problem is to obtain from network state sub-clustering database Know, the network problem being to determine.Now, the problem of cluster in sub-clustering database belonging to the base station corresponds to use-case is searched, if The network coverage and capacity problem, then can determine that the base station is above-mentioned first kind base station.
Step 304, by the network metric of multiple moulds in the network metric value of base station cluster corresponding with greatest member's probability Value compares, and determines immediate network metric value.
Determine the either cluster that base station is not belonging in sub-clustering database, the network problem for showing current base station is one and new asked Topic, expert system can not be instructed or do not occurred in the conventional system problem of network, now need base station to determine whether it Whether network problem is the network coverage and capacity problem.
Base station is using cluster corresponding to greatest member's probability as the immediate cluster of the base station network state first, then, The base station carries out the network metric value of multiple moulds in the network metric value NV of itself of acquisition and an immediate cluster Contrast.One of cluster includes multiple network state sampled values, and each network state is with a principal component vector data come table Sign, while a principal component vector data correspond to two tuples that one or more network metric value NV and control parameter CP are formed It is right, i.e. corresponding one or more two tuples pair of a PCV（NV,CP）.Each（NV,CP）To being referred to as a mould, therefore one Sub-clustering corresponds to multiple moulds.As shown above, each cluster can include multiple moulds in the sub-clustering database, and one group pair is included in each mould The network metric value and control parameter answered.
Step 305, judge base station network metric value NV and multiple moulds in difference between immediate network metric value Whether metric threshold value is more than or equal to.
If the difference is more than or equal to metric threshold value THn, step 306 is performed, if it is not, then performing step 307.
Step 306, it is first kind base station to determine the base station.
Step 307, the control parameter of base station and the control parameter in the mould where immediate network metric value are judged Whether difference is more than or equal to control parameter threshold value.

If the difference of control parameter is more than or equal to control parameter threshold value THc, step 308 is performed, if it is not, then the base station is simultaneously Non- above-mentioned first kind base station, namely the base station in the absence of capacity and covering problem.
Step 308, it is first kind base station to determine the base station.
Base station can determine whether its own is first kind base station by above-mentioned steps 301 ~ 308, if so, then base station is to association Device is adjusted to report its status information and its neighboring BS information, so that telegon is according to the multiple base station dividing cell clusters in step 201 ~ 203 pair.
Base station effectively analyzes the state of current area by the above method based on prior information, and base station whether there is and cover Lid and capacity problem realize detection and judged.
In the above-described embodiments, the calculating to each base station utility function is completed using distributed method, namely by each base Stand and voluntarily calculate, then send calculated value to telegon, judge whether that iteration is completed by telegon, and further determine that each base The configuration parameter stood.
When calculating utility function value in each base station, the utility function for defining each base station first is：
（Formula 1）
Wherein b represents base station cell sequence number, and k represents user's sequence number, KbCell b all users are represented,Represent User k descending Signal to Interference plus Noise Ratio, γkRepresent user k service rate requirement.P represents the power allocation vector of each base station of system, If network has B base station, p=[p1,p2,...,pB]；θ represents the Downtilt vector of each base station of system, if network has B Individual base station, then θ=[θ1,θ2,...,θB].The utility function shows each base station cell b performance indications ubWith its user'sValue be ordered into c% value from large to small to characterize, the value is that system is set, such as 95%.
Formula 1 is write as formula 2 after computing, as follows：
（Formula 2）
And（Formula 3）
Wherein qkUser k power is distributed in expression；vkkRepresent interference matrix in user k serving BS to user k oneself The link gain of body；θbRepresent user k serving BS b angle of declination；vlkRepresent that the serving BS of user l in interference matrix arrives User k link gain；θblRepresent user l serving BS b angle of declination；αkIt is user k power allocation factor, qk= αk·pb；Represent total descending interference that user k is subject to.For each cell, base station all can timed maintenance one it is dry Matrix table V is disturbed, if the total number of users of network is K, the table size is K × K, each element v of the interference matrixmnRepresent user Link gain of the m serving BS to user n.
For whole network, majorized function is defined as shown in Equation 4：
（Formula 4）
The majorized function of the whole network is so that the utility function of the worst base station of utility function maximizes.In other words, the whole network Optimization aim is so that the effectiveness of all base stations reaches unanimity, i.e., the effectiveness of each base station balances each other.
From formula 4, when optimizing the whole network, it is necessary first to calculate the respective utility function in each base station.Can from formula 2 See, the acquisition of the utility function of a base station needs to learn the descending interference of user, and the calculating of descending interference depends on the whole network The angle of declination θ of each base station cellbl.Reason is for downlink transfer, and sender is base station, and recipient is user, each user The signal that the descending interference being subject to is sent from other base stations, i.e., this descending interference are the antenna parameter settings by other base stations Influence.Therefore, the descending utility function of a base station cell is calculated, it is necessary to need to know the antenna configuration parameters of other base stations Setting, the complexity and signaling consumption of calculating require very high.
Based on this, the present invention program utilizes the principle of the pairing of lines up and down, proposes by the virtual up effectiveness of calculation base station Function carrys out the equivalent utility function for realizing base station down, this have the advantage that：Calculation base station virtually up utility function when, Because sender is user, recipient is base station, user of the uplink interference that each base station is subject to from other base station cells, i.e., This uplink interference is not influenceed by the antenna configuration parameters of other base stations, and is only depended on and matched somebody with somebody with the antenna parameter of this base station Put.Therefore, the up utility function of a base station is calculated, it is only necessary to consider the setting of the antenna configuration parameters of own base stations, count The complexity and signaling consumption of calculation substantially reduce.It was demonstrated that by optimizing virtual ascending getable parameter configuration, it is equivalent Corresponding parameter configuration when descending Performance optimization.The characteristics of using the upper and lower pairing of lines, the calculating of above-mentioned base station utility function Optimization with whole net utility function is converted to formula 5 and formula 6 from formula 3 and formula 4：
（Formula 5）
υ′kk(θb)-αkυkk(θb)/γk（Formula 6）
It is worth noting that, after by conversion, the user of each base station cell disturbs the θ only with this base stationbIt is related.It is this The way of equivalent up utility function is optimized, due to the antenna configuration calculated only with this base station of the utility function of each base station Parameter is related, therefore can realize the calculating of semi, i.e., each base station system configuration parameter according to known to itself is counted Itself utility function is calculated, and optimizes the utility function of itself by optimizing the parameter configuration of itself, leads to too small amount of information and hands over Mutually, the coordination of each base station utility function of whole net is can be achieved with, realizes the optimization of the whole network utility function.
Then, each base station can calculate utility function, can be specifically each transmission power of base station to this base station And the valued space of Downtilt makees poor search, in each transmission power and Downtilt of this base station and sub-clustering The current transmission power in other base stations or transmission power and Downtilt calculate utility function, obtain utility function value, and The utility function value of acquisition is carried out with according to one group of transmission power on this base station and the corresponding utility function value of Downtilt Compare, finally, the utility function value of telegon will be reported to as the base station by taking the utility function value of minimum, and will produce the effect The antenna configuration parameters updated by the use of the transmission power or transmission power and Downtilt of this base station of functional value as the base station.
After the base station of each cell cluster calculates utility function in the manner described above, utility function value is sent to telegon, if Telegon judge the utility function value between each base station in a cell cluster difference be more than functional value threshold value then by each base station more Antenna configuration parameters after new send to each cell cluster base station, base station and are iterated to calculate and imitated according to the antenna configuration parameters of renewal again With function, until the difference of the utility function value in the same cell cluster that telegon receives between each base station is less than or equal to functional value Threshold value, iteration terminate.The function threshold is set by operator according to artificial experience, and such as 0.001.Each base station calculates in cell cluster Obtained utility function if mutually reached unanimity, then illustrates fixed point iteration algorithmic statement after fixed point iteration, and then each small After the utility function of area's cluster reaches unanimity respectively, that is, each base station configuration parameter that have found network optimum is set, and is made defined The whole network utility function（Formula 4）Optimized.
The present invention program realizes the network optimization based on the algorithm of fixed point iteration, is based primarily upon two reasons：1）It was demonstrated that Optimization system utility function based on interference function can obtain system optimal by fixed point iteration method and configure；2）Fixed point iteration Method has that algorithm is simple, convergence is fast, can（Half）The advantages that distributed implementation.
In another embodiment, KPI, NV and CPV before optimization further can also be added into existing by telegon The problem of network state sub-clustering database use-case（The network coverage and capacity problem use-case）In cluster, the sub-clustering database is updated.
