According to the networking frequency range of Target cell and the similarities and differences of the networking frequency range of relevant adjacent area, the candidate of Target cell is determined frequently The value range of point sum.

Citing illustrates, if the configured frequency point in adjacent area that is concerned with is 900MHz, 906MHz, the networking frequency range of Target cell For 900MHz~910MHz, then the networking frequency range of Target cell and the networking frequency range of relevant adjacent area are identical, i.e. identical networking.If mesh The networking frequency range for marking cell be 880MHz~890MHz, then the networking frequency range of the networking frequency range of Target cell and relevant adjacent area is not Together, i.e. inter-frequency networking.

It is preferred that if the networking frequency range of Target cell is identical with the networking frequency range of relevant adjacent area, it is determined that relevant adjacent area is The number of frequency point is configured, and causes candidate's frequency point sum of Target cell not less than the number of the relevant configured frequency point in adjacent area；

If the networking frequency range of Target cell is different from the networking frequency range of relevant adjacent area, candidate's frequency point sum of Target cell It is positive integer not less than default frequency point sum K, K.

That is, when Target cell and relevant adjacent area identical networking, the sum of candidate's frequency point of Target cell is more than Equal to the number of the configured frequency point in relevant adjacent area, it is assumed for example that candidate's frequency point sum of Target cell is N, and adjacent area of being concerned with is configured The number of frequency point is M, then N >=M；

When Target cell and relevant adjacent area inter-frequency networking, the value of K can be 1, can also be arranged as required to corresponding Value, as long as meeting that K is positive integer.

In a step 102, according to the frequency shift (FS) step-length of Target cell, candidate's frequency point sum is determined.

It is preferred that the frequency shift (FS) step-length and candidate's frequency point sum of Target cell meet following equation：

Specifically, exactly determine to meet N >=M,Frequency shift (FS) step-length d, according to Definite d, substitutes into formulaIn obtain candidate frequency point sum N, wherein due to true by this method The value of the frequency shift (FS) step-length d made is not unique, it is preferred that the frequency shift (FS) from the value range for meeting candidate's frequency point sum Frequency shift (FS) step-length of the frequency shift (FS) step-length of maximum as the Target cell is selected in step-length.

Wherein, initial frequency shift (FS) step-length d₀, can should determine that according to different bandwidth of base station is adaptive.

Such as, it is proposed that d₀For the half of bandwidth of base station.When bandwidth of base station is 20MHz, then suggest d₀For 10MHz；Work as base station When bandwidth is 15MHz, then suggest d₀For 5MHz；When bandwidth of base station is for 10MHz, then suggest d₀For 2.5MHz；When bandwidth of base station is During 5MHz, then suggest d₀For 2MHz；When system bandwidth is 3MHz, then suggest d₀For 1.5MHz.

Then work of the frequency point for meeting preset condition as the Target cell is selected from all candidate's frequency points Frequency point.

It is preferred that step 104 specifically includes：

Being concerned with deletion frequency point solution sequence, it is small to be spaced between the configured frequency point in adjacent area and the frequency point configured with relevant adjacent area In the frequency point of frequency shift (FS) step-length, candidate's frequency point solution sequence is obtained；

If it is determined that candidate's frequency point solution sequence is not sky, it is determined that Target cell working frequency points to have matched somebody with somebody with relevant adjacent area The frequency point of the sum of absolute value being spaced between the frequency point put maximum, if the absolute value being spaced between the frequency point configured with relevant adjacent area it With maximum corresponding frequency point there are multiple, then working frequency points of the frequency point as Target cell are therefrom selected；

If it is determined that candidate's frequency point solution sequence for sky, it is determined that Target cell working frequency points be and relevant adjacent area coherence Minimum frequency point, if with the frequency point of relevant adjacent area coherence minimum there are multiple, therefrom selection one is as Target cell Working frequency points；

Wherein, according to the size of relevant adjacent area Reference Signal Received Power and/or with the base distance between sites of relevant adjacent area Distance determines the size with relevant adjacent area coherence.

Specifically, frequency point solution sequence is f₁、f₂、…、f_n, the frequency point for adjacent area of being concerned with is f₅、f₇、f₉, with relevant adjacent area Interval is f less than the frequency point of frequency shift (FS) step-length between the frequency point of configuration₈, then candidate's frequency point solution sequence is f₁、f₂、f₃、f₄、f₆、 f₁₀、…、f_n, from candidate's frequency point solution sequence f₁、f₂、f₃、f₄、f₆、f₁₀、…、f_nSelect a frequency point configured with relevant adjacent area Between the maximum frequency point of the sum of the absolute value that is spaced.

It is to determine mesh with relevant adjacent area coherence according to the working frequency points of Target cell if candidate's frequency point solution sequence is sky Mark the working frequency points of cell.

Wherein, adjacent area RSRP (Reference Signal Received Power, Reference Signal Received Power) is smaller, It is then smaller with the coherence of relevant adjacent area；It is bigger with the base station spacing of adjacent area, then it is smaller with the coherence of relevant adjacent area.

Wherein, priority ranking rule is：Since the frequency point solution sequence first frequency point, using preset value as step-length Value, frequency point is chosen from frequency point solution sequence and is arranged in order to obtain the first frequency point sequence according to order from small to large, and will choosing The frequency point gone out is deleted from frequency point solution sequence and obtains the second frequency point sequence；

Wherein, preset value is not less than bandwidth of base station.

Specifically, it is assumed that frequency point solution sequence is f₁、f₂、…、f₂₀, preset value X, wherein X >=W, W is bandwidth of base station, Illustrated so that X=W, frequency shift (FS) step-length d are W/2 as an example.

2) the first frequency point sequence f₁、f₃、f₅…、f₁₉In maximum be f₁₉, judge the second frequency point sequence f₂、f₄、f₆…、 f₂₀In whether have more than f₁₉Frequency point, there are f₂₀More than f₁₉, then from f₂₀Start, from f₂、f₄、f₆…、f₂₀Select at intervals of WMHz Frequency point, be sequentially arranged in the first frequency point sequence f from big to small₁、f₃、f₅…、f₁₉F₁₉Behind, due to f₂、f₄、f₆…、f₂₀ In without and f₂₀At intervals of the frequency point of WMHz, then only by f₂₀It is placed in f₁、f₃、f₅…、f₁₉The 3rd frequency point sequence f is obtained below₁、f₃、 f₅…、f₁₉、f₂₀；Delete f₂、f₄、f₆…、f₂₀In frequency point f₂₀, obtain the 4th frequency point sequence f₂、f₄、f₆…、f₁₈；

3) the 4th frequency point sequence f is judged₂、f₄、f₆…、f₁₈In whether there is f₁The point of+d, there are f₂=f₁+ d, then from f₂Open Begin to select the frequency point f at intervals of WMHz₂、f₄、f₆…、f₁₈, order from small to large is added to the 3rd frequency point sequence f successively₁、f₃、 f₅…、f₁₉、f₂₀Behind obtain f₁、f₃、f₅…、f₁₉、f₂₀、f₂、f₄、f₆…、f₁₈, it is f so far to have completed frequency point solution sequence₁、 f₂、…、f₂₀Whole sequences, obtain orderly frequency point solution sequence f₁、f₃、f₅…、f₁₉、f₂₀、f₂、f₄、f₆…、f₁₈；

If also continue to judge to whether there is f in remaining frequency point there are unsorted frequency point in the 4th frequency point sequence₁+2*d Frequency point, if there is no if continue to judge to whether there is f in remaining frequency point₁The frequency point of+3*d, if in the presence of if from f₁+ 2*d starts to select The frequency point gone out at intervals of WMHz comes behind the 3rd frequency point sequence sequenced from small to large, then proceedes to judge whether f₁+ 3*d, until f₁The value of+i*d is more than the maximum frequency point in unsorted frequency point, then terminates to judge.

If 4) remaining frequency point is sequentially arranged in from small to large also there are unsorted frequency point in the 4th frequency point sequence State behind the 3rd frequency point sequence sequenced.

As preset value X ＞ W, its sortord is similar with aforesaid way, and details are not described herein.

It is if triggering configuration initialization frequency point in base station during opening base station, the working frequency points selected are current i.e. as base station Working frequency points.

During being run in base station, the frequency point that the relevant adjacent area of monitoring base station is configured has renewal, then it is preferred that If position of the current working frequency points of Target cell in orderly frequency point solution sequence is in the working frequency points of definite Target cell Afterwards, then current working frequency points using the working frequency points of definite Target cell as Target cell；

If position of the current working frequency points of Target cell in orderly frequency point solution sequence is in definite Target cell Before working frequency points, then current working frequency points using the current working frequency points of Target cell as Target cell.

If the current working frequency points of Target cell are not in frequency point solution sequence, by the work frequency of definite Target cell Current working frequency points of the point as Target cell.

Specifically, if current working frequency is f₅, in orderly frequency point solution sequence f₁、f₃、f₅…、f₁₉、f₂₀、f₂、f₄、 f₆…、f₁₈In, if the working frequency points of the Target cell reconfigured are f₁, then current working frequency points are updated to f₁If again The working frequency points of the Target cell of configuration are f₇, then current working frequency points are also f₅If current working frequency is f₀, do not having Sequence frequency point solution sequence f₁、f₃、f₅…、f₁₉、f₂₀、f₂、f₄、f₆…、f₁₈In, if the working frequency points of the Target cell reconfigured are f₁, then current working frequency points are updated to f₁。
