For another example network system can receive the configured information of other equipment transmission, the configured information is used for indication problem Cell, network system determine problem cells according to the configured information.

After network system determines problem cells, the cell to be adjusted of the problem cells can be built.Cell adjustment is waited to adjust Whole parameter is different, and the cell to be adjusted of structure is also different, and rear extended meeting elaborates.Network system can use various ways true Cell is assessed corresponding to fixed each cell to be adjusted.

Alternatively, in embodiments of the present invention, infinite as example, the network system can be waited to adjust according to each The positional information of whole cell, it is determined that the assessment cell of each cell to be adjusted；

Specifically, the homogeneous-frequency adjacent-domain adjacent with the cell geographical position to be adjusted can be waited to adjust by network system as this The assessment cell of whole cell.For example, network system can treat the adjacent multiple homogeneous-frequency adjacent-domains of the cell to be adjusted according to this The distance between adjustment cell is from closely to being far ranked up, the nearest one or several same frequencies of the chosen distance cell to be adjusted are adjacent Assessment cell of the area as the cell to be adjusted.

Alternatively, in embodiments of the present invention, infinite as example, the network system can also be treated according to each The switching times between cell and corresponding homogeneous-frequency adjacent-domain are adjusted, it is determined that the assessment cell of each cell to be adjusted.

Specifically, it is to be adjusted as this can will to switch close homogeneous-frequency adjacent-domain with the cell to be adjusted for the network system The assessment cell of cell.For example, network system can be according to cell switches successfully time two-by-two in the traffic statistics data of cell to be adjusted Number or handover request number, the switching times of the cell to be adjusted and homogeneous-frequency adjacent-domain are counted, by the multiple with frequency of cell to be adjusted Adjacent area according to the switching times of the cell to be adjusted are descending is ranked up, selection switches most close with the cell to be adjusted Assessment cell of one or several homogeneous-frequency adjacent-domains as the cell to be adjusted.

It should be understood that determination problem cells listed above and the method for assessment cell are merely exemplary to illustrate, should not be right The present invention forms any restriction, and the number that cell is assessed corresponding to each cell to be adjusted can be carried out according to being actually needed Selection, the present invention do not limit herein.

It should also be understood that network system can be by the engineering parameter and/or configuration information of each cell to be adjusted, obtaining should The positional information of each cell to be adjusted；Network system this can each be treated by the traffic statistics data acquisition of each cell to be adjusted Adjust the switching times of cell and adjacent area.Further, the network system can also obtain each to be adjusted by other means The positional information or handover information of cell, the present invention do not limit herein.

More than, the method 100 of adjustment cell according to embodiments of the present invention is described in detail from the angle of entirety.Hereinafter, This method 100 is described in detail from the angle of power adjustment and antenna feeder adjustment (angle of declination adjustment) respectively.

First, power adjusts

Alternatively, in embodiments of the present invention, infinite as example, at least one cell to be adjusted at least may be used With including following two situations：

Situation one (cell to be adjusted includes crucial cell to be adjusted)

Under normal circumstances, it is to solve the covering problem of problem cells or capacity why some cells to be adjusted Problem.This can be used to solve covering problem or the cell to be adjusted of capacity problem is referred to as crucial cell to be adjusted.

For example, problem cells are weak covering problem cells, can be solved by adjusting the transmission power levels of the problem cells The weak covering problem of the problem cells, now the problem cells can be as crucial cell to be adjusted.In another example problem cells are Pilot pollution cell, it is generally the case that the pilot pollution problem, be for covering one group of overlapping cell.Can be small according to servicing Pilot pollution MI ratio in multiple MI in area, it is pilot pollution cell to determine the serving cell.It is determined that during pilot pollution MI, Pollution cell-of-origin corresponding to the pilot pollution cell can be recorded, and contribute according to pilot pollution to each pilot pollution MI Ratio is higher than the indexs such as each class cover problem ratio of each pollution cell-of-origin of certain thresholding, load, determines that the pilot pollution is small The adjustment direction of at least one cell to be adjusted and at least one cell to be adjusted corresponding to area.Wherein, pilot pollution MI Judgment mode include meet below equation：

ServerCell_RSCP >=RSCP thresholdings (1)

N_{|ServerCell_RSCP-NeighborCell_RSCP|<Overlapping coverage threshold}>Strong number of pilots thresholding (2)

Wherein, ServerCell_RSCP is the reception letter for the main serving cell (ServerCell) that terminal device receives Number power (Received Signal Code Power, referred to as " RSCP "), N_{|ServerCell_RSCP-NeighborCell_RSCP|<Overlapping coverage threshold}For the number of strong pilot tone.If terminal device receives leading for main serving cell The absolute value that frequency and the terminal device receive the difference of the pilot tone of adjacent area (NeighborCell) (such as A cells) is more than overlapping covering Thresholding, then the pilot tone for the A cells that terminal device receives is a strong pilot tone.When the number of strong pilot tone in a MI is more than strong pilot tone Number thresholding, it is determined that the MI is pilot pollution MI.In other words, the MI is determined when a certain bar MI meets formula (1) and (2) For pilot pollution MI.

It should be understood that in the umts system, can be gone to weigh the coverage condition of respective cell with the PSCP, in LTE system, It can be gone to weigh accordingly with Reference Signal Received Power (Reference Signal Receiving Power, referred to as RSRP) The coverage condition of cell.

Therefore, dominant pilot cell and the reception level value difference of adjacent area can be received by increasing terminal device, solves to lead Frequency pollution problem.According to the pilot pollution cell build at least one cell to be adjusted can include the pilot pollution cell and At least one of pollution cell-of-origin of the pilot pollution cell, wherein, the pilot pollution cell and pollution cell-of-origin can be with As crucial cell to be adjusted, by adjusting the transmission power of crucial cell to be adjusted, solves the pilot tone of the pilot pollution cell Pollution problem.

(at least one cell to be adjusted not only includes crucial cell to be adjusted to situation two, while also includes each crucial The same coverage cell of cell to be adjusted)

When being adjusted to crucial cell to be adjusted, each crucial cell to be adjusted is corresponding with the same frequency range of covering with it The adjacent area of pilot frequency point be likely to become between each other it is blind cut adjacent area, in order to ensure blind to be cut into work(, it is necessary to which so that the key is to be adjusted small Area is consistent with the pilot power of the same coverage cell of key cell to be adjusted (covering is consistent).Therefore, to crucial to be adjusted , it is necessary to synchronize adjustment to the same coverage cell of key cell to be adjusted when cell is adjusted.Wherein, synchronous adjustment is Finger is adjusted using identical value to be adjusted to the same coverage cell of key cell to be adjusted and key cell to be adjusted, For example, A cells are crucial cell to be adjusted, the same coverage cell of A cells is B cells and C cells.By the transmission power of A cells Value increases xdBM, it is necessary to increase xdBM respectively to the transmission power level of the B cells and C cells.

Alternatively, the network system can be known according to the engineering parameter and/or configuration information of each key cell to be adjusted The same coverage cell of not each crucial cell to be adjusted.

It should be noted that crucial cell to be adjusted listed above is merely illustrative, the present invention should not be formed Limit.The method of any cell adjustment, the same coverage cell of a kind of cell to be adjusted or altogether antenna feeder cell are also served as to be adjusted Cell synchronizes adjustment and each falls within protection scope of the present invention.

Network system can according to corresponding to the cell to be adjusted that the first initial MI includes the first value to be adjusted, determine this The variable quantity of the reception level value for the cell to be adjusted that one initial MI includes, so as to obtain the first renewal MI.Alternatively, the network System can receive the corresponding relation of the variable quantity of level value and described by the variable quantity and cell of cell transmission performance number First value to be adjusted corresponding to the cell to be adjusted that first initial MI includes, determine the cell to be adjusted that the first initial MI includes Reception level value variable quantity, so as to obtain the first renewal MI.

Specifically, characteristic of the power adjustment with linear change.Under normal circumstances, it can be assumed that the transmitting work(of transmitting terminal When rate value changes, receiving terminal is identical in the variable quantity of the reception level value of the reception signal in different reception places.Further Ground, it may also be assumed that the variable quantity that the variable quantity of the transmission power level of transmitting terminal receives level value with receiving terminal is identical.For example, A Cell transmission performance number is P₀, the reception level value that terminal device receives the A cells at D1 is P₁, terminal device connects at D2 The reception level value for receiving the A cells is P₂.The value to be adjusted of the A cell transmission performance numbers includes Δ p, small to the A using Δ p (transmission power level of A cells is changed into P after adjusting after the transmission power level in area is adjusted₀+ Δ p), it is believed that terminal is set The standby variable quantity that the reception level value of the A cells is received in D1 and D2 is that (after adjusting, terminal device is at D1 and D2 by Δ p The reception level value for receiving the A cells becomes P respectively₁+ Δ p and P₂+Δp)。

, should [x if carrying out power adjustment to cell to be adjusted still by taking table 1 as an example₁, y₁, z₁]=[1,3,1], according to cell The variable quantity and cell of transmission power level receive the variable quantity of level value, it is determined that should [x₂, y₂, z₂]=[1,3,1].This is at the beginning of first Beginning MI updates to obtain the first renewal MI can be as shown in table 2.

Table 2

Therefore, can be according to the change of cell transmission performance number if carrying out power adjustment at least one cell to be adjusted Change amount and cell receive the corresponding relation of the variable quantity of level value, and each value to be adjusted is mapped into each cell to be adjusted receives The variable quantity of level value, so as to which the plurality of initial MI is updated into multiple renewal MI.

2nd, antenna feeder adjustment (angle of declination adjustment)

Alternatively, in embodiments of the present invention, infinite as example, similar with power adjustment, this at least one Individual cell to be adjusted can also include at least following two situations：

Situation one (cell to be adjusted includes crucial cell to be adjusted)

Wherein, the related description of key cell to be adjusted may refer to crucial cell to be adjusted in power adjustment above Related description, the present invention will not be repeated here.

(at least one cell to be adjusted not only includes crucial cell to be adjusted to situation two, while is also treated including the key Adjust the common antenna feeder cell of cell)

When being adjusted to crucial cell to be adjusted, because the corresponding common antenna feeder cell of crucial cell to be adjusted is total to Angle of declination adjustment is carried out with an antenna, therefore to crucial cell to be adjusted, the common antenna feeder of key cell to be adjusted can be caused The consistency adjustment of cell.

Alternatively, the network system can identify according to the engineering parameter and/or configuration information of key cell to be adjusted The common antenna feeder cell of key cell to be adjusted.

Network system can according to corresponding to the cell to be adjusted that the first initial MI includes the first value to be adjusted, determine this The variable quantity of the reception level value for the cell to be adjusted that one initial MI includes, so as to obtain the first renewal MI.Alternatively, network system System can determine the change of the reception level value for the cell to be adjusted that the first initial MI includes at least through following two modes Amount.

Mode one,

In embodiments of the present invention, infinite as example, each initial MI includes Timing Advance (Timing Advance, referred to as " TA "), according to the variable quantity of cell angle of declination, TA and the variable quantity of antenna damping mapping table and institute The first value to be adjusted corresponding to the cell to be adjusted that the first initial MI includes is stated, it is to be adjusted small to determine that the first initial MI includes The variable quantity of the reception level value in area.

Specifically, it is generally the case that in the case of assume that surrounding enviroment are constant, it is believed that the variable quantity of antenna damping It is exactly the variable quantity (i.e. the variable quantity of cell reception level value) of terminal device received signal strength.Wherein, cell angle of declination The mapping table of variable quantity, TA and the variable quantity of antenna damping can be as shown in table 3.

Table 3

By taking table 4 as an example, if carrying out angle of declination adjustment to cell to be adjusted, the TA=2 that the first initial MI includes, wherein, A Cell is cell to be adjusted, the angle of declination variable quantity x of the A cells₁=1, according to above-mentioned mapping table, determine antenna damping variable quantity For 2, variable quantity x is obtained so as to which the cell receives level value₂=2.The first initial MI updates to obtain the first renewal MI can be such as table 4 It is shown.

Table 4

Therefore, can be according to the change of cell angle of declination if carrying out angle of declination adjustment at least one cell to be adjusted The mapping table of amount, TA and the variable quantity of antenna damping, each value to be adjusted is mapped to each cell to be adjusted and receives level value Variable quantity, so as to which the plurality of initial MI is updated into multiple renewal MI.

Mode two,

In embodiments of the present invention, infinite as example, each initial MI includes TA, according to the first initial MI Including cell to be adjusted corresponding to the TA that includes of the first value to be adjusted and the first initial MI, determine that the first initial MI includes Cell to be adjusted reception level value variable quantity.

The difference of mode one and mode two is that mode two is without the mapping table.The network system can be according under cell The variable quantity and TA at inclination angle, the corresponding relation with antenna damping variable quantity, determine the cell to be adjusted that the first initial MI includes Reception level value variable quantity.Either, the TA all sames that each initial MI includes in the plurality of initial MI, the network system Can according to the corresponding relation of the variable quantity of cell angle of declination and antenna damping variable quantity, it is determined that each initial MI include wait to adjust The variable quantity of the reception level value of whole cell.

It should be noted that the mapping of the variable quantity of cell angle of declination listed above, TA and the variable quantity of antenna damping Table is merely illustrative, and should not form any restriction to the present invention, present invention is also not necessarily limited to this.

It should also be noted that, network system can be counted according to the TA, engineering parameter and day line file that terminal device reports Calculate at different TA after the certain number of degrees of angle of declination change, antenna damping variable quantity, and then obtain angle of declination variable quantity~TA~antenna Attenuation change amount mapping table.The network system can also obtain the mapping table by other means.The mapping table can be used for pair The Pre-Evaluation of subsequent cell adjustment.

Detailed how respectively from the angle of power adjustment and the angle of antenna feeder adjustment according to the first initial MI above Including cell to be adjusted corresponding to the first value to be adjusted, determine the reception level of the cell to be adjusted that the first initial MI includes The variable quantity of value.Hereinafter, describe in detail how according to multiple renewal MI predict at least one cell to be adjusted pass through this at least Cell condition after one the first value adjustment to be adjusted.

For example, in embodiments of the present invention, infinite as example, this is according to the plurality of renewal MI, it is determined that this is extremely Cell condition of few cell to be adjusted after at least one first value adjustment to be adjusted, can include：It is more according to this The activated state MI of first community quantity (or variable quantity of quantity) at least two cell that individual renewal MI includes, it is determined that should At least one cell to be adjusted is after at least one first value adjustment to be adjusted, (or the load of the load capacity of the first community The variable quantity of amount).

Specifically, in a MI, if the reception level that terminal device receives certain cell meets following three condition, It is considered that the cell is the activation collection cell of the MI：

The reception level that condition 1, terminal device receive the cell is more than or equal to the minimum reception level demand of terminal device；

The reception level that condition 2, the strongest received of terminal device level-terminal device receive the cell is less than or equal to electricity Adjustment thresholding；

The number of the activation collection cell of condition 3 is less than or equal to maximum activation collection number (maximum activation collection under normal circumstances 3) number is.

If including some cell in some MI activation collection cell, the MI may be considered the cell one is sharp State MI living.Under normal circumstances, three most strong cells of terminal device reception signal can be as the activation of the MI in some MI Collect cell.Further, network system can count the quantity of the activated state MI of first community in multiple renewal MI, in order to right The load capacity of the first community is predicted.For example, it is assumed that A cells are a cell to be adjusted, in 100 initial MI, A is small The activated state MI in area number is 70, and this 100 initial MI are adjusted into 100 more using at least one first value to be adjusted After new MI, the activated state MI of the A cells is changed into 60.The activated state MI of the cell A to be adjusted reduces 1/7, accordingly can be with That thinks the cell A load capacity to be adjusted reduces 1/7.Alternatively it is also possible to the variable quantity of activated state quantity is not counted, according to If judge the activated state MI of the A cells as 60 corresponding load capacity.

In another example in embodiments of the present invention, infinite as example, this is according to the plurality of renewal MI, it is determined that should Cell condition of at least one cell to be adjusted after at least one first value adjustment to be adjusted, including：According to the plurality of Terminal device takes the downlink physical resource block PRB of first community quantity (or variable quantity of quantity) in renewal MI, it is determined that At least one cell to be adjusted is after at least one first value adjustment to be adjusted, the load capacity of first cell to be adjusted (or variable quantity of load capacity).

Specifically, it is the first of first community that network system, which can count strongest received level value in the plurality of renewal MI, Cell update MI quantity, and then count the downlink physical money that terminal device in each first community renewal MI takes first community Source block PRB (Physical Resource Block) quantity.The network system takes according to terminal device in multiple renewal MI The PRB quantity (or variable quantity of quantity) of the first community, predict the load capacity (or variable quantity of load capacity) of first community.

It should be noted that in the umts system, the network system can be according to the activated state MI of first community quantity Predict the load capacity of the first community；In LTE system, the network system can be according to the PRB of the first community of occupancy number Amount predicts the load capacity of the first community.One or more cells at least two cells can be predicted in embodiments of the present invention Load capacity and coverage condition.

It should be noted that the first community in the embodiment of the present invention can be small with any one at least two cells Area, the prediction to any one cell load amount at least two cell may refer to the pre- of the load capacity of the first community Survey, for sake of simplicity, the present invention will not be repeated here.

Alternatively, preset standard can include small district's groups pollution preset standard, small district's groups cover empty preset standard, cell Weak covering at least one of the preset standard and cell load preset standard of group.

For example, preset standard can include small district's groups pollution preset standard, reaching small district's groups pollution preset standard is included completely Sufficient below equation：

Wherein,For according to cell at least one first multiple renewal MI to be adjusted being worth to Group pilot pollution MI ratios,For small district's groups pilot pollution MI ratios in the plurality of initial MI；Tolerate thresholding for pollution deterioration.Small district's groups pilot pollution MI ratios refer to：(all pilot pollution MI in small district's groups Number)/(all MI numbers in small district's groups).Wherein, pilot pollution MI judgment mode may refer to associated description above, For sake of simplicity, the present invention repeats no more again.Accordingly, with respect to small district's groups pilot pollution MI ratios corresponding to the plurality of initial MI For, if after being adjusted, small district's groups pilot pollution MI ratios do not increase in the plurality of renewal MI or increment is not less than pollution Deteriorate tolerance thresholding, it is believed that the cell condition reaches small district's groups pollution preset standard.

In another example the preset standard can also include the weak covering preset standard of small district's groups, it is default to reach the weak covering of small district's groups Standard includes meeting below equation：

Wherein,For according to cell at least one first multiple renewal MI to be adjusted being worth to The weak covering MI ratios of group,For the small weak covering MI ratios of district's groups in the plurality of initial MI, Deteriorate tolerance thresholding for weak covering.

Specifically, the weak covering MI ratios of small district's groups refer to：(all weak covering MI numbers in small district's groups)/(small district's groups Interior all MI number).Wherein, the weak covering MI includes：If the reception level value of main serving cell is less than weak coverage threshold, really The fixed MI is weak covering MI.For the small weak covering MI ratios of district's groups corresponding to the plurality of initial MI, if by After adjustment, the small weak covering MI ratios of district's groups do not increase in the plurality of renewal MI, or increment deteriorates tolerance thresholding not less than weak covering, Think the weak covering preset standard of the small district's groups of the cell condition.

For another example the preset standard can also include covering empty preset standard, reaching the empty preset standard of covering includes Meet below equation：

Wherein,For according to corresponding at least one first multiple renewal MI to be adjusted being worth to Small district's groups cover empty MI ratios,Empty MI ratios are covered for small district's groups corresponding to a plurality of initial MI Example,Deteriorate tolerance thresholding for covering cavity.

Specifically, small district's groups cover empty MI ratios and referred to：(all empty MI of covering numbers in small district's groups)/it is (small All MI number in district's groups).Wherein covering empty MI includes：If main serving cell receives level value and received less than covering cavity Level value thresholding, the MI is determined to cover empty MI.Empty MI is covered accordingly, with respect to small district's groups corresponding to the plurality of initial MI For ratio, if after being adjusted, small district's groups cover empty MI ratios and not increased in the plurality of renewal MI, or increment not less than Covering cavity deteriorates tolerance thresholding, it is believed that the cell condition reaches small district's groups and covers empty preset standard.

For another example the preset standard also includes cell load preset standard, reaching cell load preset standard includes：More In individual renewal MI, after the cell to be adjusted adjustment for improving transmission power level, the cell to be adjusted of the raising transmission power level Load capacity growth not less than load tolerate thresholding, for reduce transmission power level cell to be adjusted adjustment after, the reduction The growth that the load capacity of cell is assessed corresponding to the cell to be adjusted of transmission power level tolerates thresholding not less than load, it is believed that this is small Area's situation reaches load preset standard.

Further, describe in detail above and how multiple renewal MI obtained according at least one first value to be adjusted, And according to renewal MI, determine the corresponding target adjustment that at least one first value to be adjusted is at least one cell to be adjusted Value.Under normal circumstances, the network system is it is determined that the target adjustment value of each first value cell to be adjusted for corresponding to be adjusted It can include before：

According at least one second value to be adjusted, the cell to be adjusted included to each initial MI in the plurality of initial MI First reception level value be updated, obtain it is multiple second renewal MI, wherein, this it is at least one second it is to be adjusted value and this extremely A few cell to be adjusted is corresponded, and the plurality of second renewal MI and the plurality of initial MI are corresponded；

According to the plurality of second renewal MI, predict each cell to be adjusted after the corresponding first value adjustment to be adjusted Cell condition；

Determine cell condition of at least one cell to be adjusted after at least one first value adjustment to be adjusted Cell condition of the comprehensive score higher than at least one cell to be adjusted after at least one second cell adjustment to be adjusted Comprehensive score.

Specifically, at least one value to be adjusted can form a value set to be adjusted.For example, at least one first treats Adjusted value can form the first value set to be adjusted；At least one second value to be adjusted can form the second value set to be adjusted. Under normal circumstances, it is determined that before the target adjustment value of each cell to be adjusted, can predict each in multiple value sets to be adjusted Cell condition corresponding to value set to be adjusted.Wherein, the corresponding one group of renewal MI of a value set to be adjusted.One group of renewal MI is corresponding A kind of cell condition.Network system can be predicted to multiple value sets to be adjusted, from the plurality of value set to be adjusted really Fixed most preferably value set to be adjusted is as target adjustment value set.Alternatively, network system can obtain the plurality of to be adjusted Value set.For example, multiple value sets to be adjusted can be determined according to the current transmission power level of the cell to be adjusted, can also root The reception level value that cell to be adjusted is received according to terminal device determines multiple value sets to be adjusted, can also be true according to other method Fixed multiple value sets to be adjusted.Further, it is assumed that it is respectively A cells and B cells, it is necessary to the A to have two cells to be adjusted Cell and B cells are adjusted respectively.Wherein, the value to be adjusted of A cells is [x₁, x₂], the value to be adjusted of B cells is [y₁, y₂].The value set to be adjusted of the A cells and B cells can include [x₁, y₁]、[x₁, y₂]、[x₂, y₁] and [x₂, y₂].Now, should Two cells to be adjusted can correspond to four value sets to be adjusted.The number of value set to be adjusted can be according to each to be adjusted small The number of value to be adjusted corresponding to area determines, can also be determined according to other modes, and the present invention does not limit herein.

If cell condition corresponding to multiple value sets to be adjusted is satisfied by preset standard, can each be treated with weighted calculation Comprehensive score corresponding to value set is adjusted, the value to be adjusted chosen in comprehensive score highest value set to be adjusted is adjusted as target Whole value (in embodiments of the present invention, one group of value set to be adjusted of the comprehensive score highest is the first value set to be adjusted).

For example, network side equipment obtains first group according at least one first value (the i.e. first value set to be adjusted) to be adjusted MI is updated, network side equipment obtains second group of renewal according at least one second value (the i.e. second value set to be adjusted) to be adjusted MI.Wherein, first group of renewal MI corresponds to multiple renewal MI above, and second group of renewal MI corresponds to above more Individual second renewal MI.The score of each evaluation factor in first group of renewal MI is determined, is determined in second group of renewal MI The score of each evaluation factor, the evaluation factor include small district's groups pilot pollution factor, the weak covering factor of small district's groups, small district's groups and covered At least two covered in empty factor, cell load factor, it is determined that the weight of each evaluation factor, first group described in weighted calculation Update MI comprehensive score and the comprehensive score of second group of renewal MI；Fixed first group of renewal MI comprehensive score is higher than institute State second group of renewal MI comprehensive score highest.Wherein it is possible to the weight of each evaluation factor is determined at random, can also be according to one The demand of a little actual conditions, the demand of cell or user determines the weight of each evaluation factor.For example, can be according to some situations The weight of cell load factor is arranged to 70%, the weight sum of other evaluation factors is 30%.Choose comprehensive score highest One group of renewal MI corresponding to target adjustment of the value to be adjusted as at least one cell to be adjusted in value set to be adjusted Value.

It is alternatively possible to formulate Score Lists, determined each to comment the score of factor in every group of renewal MI according to Score Lists.

It should be noted that the method listed above for setting the goal adjusted value really is merely illustrative, should not be to this hair It is bright to form any restriction.Network system can also determine the target adjustment value of cell to be adjusted using other method.

It should also be noted that, preset standard listed above is merely illustrative, the present invention should not be formed any Limit, the preset standard can also include other and be used to weigh MPS process situation or the standard of loading condition.

Above in association with multiple renewal MI, the Adjusted Option for adjusting cell is predicted, and then can determine and each wait to adjust Target adjustment value corresponding to whole cell.Hereinafter, the method for introducing a kind of cell adjustment according to another embodiment of the present invention.Fig. 4 It is a kind of schematic flow Figure 200 of the method for cell adjustment according to another embodiment of the present invention, as shown in figure 4, this method 200 include：
