Abstract

The invention relates to the technical field of wireless communication, in particular to a method and a device for determining working frequency points of cells, aiming to solve the problem of poor performance of networks caused by the fact that the configuration manner of the working frequency points hardly reaches the low network interference when the high spectrum utilization ratio is used in the prior art. The method comprises the following steps: triggering a target cell and subsequently selecting frequency points to determine a value range of a total number of candidate frequency points of the target cell; selecting one of frequency shift steps in the value range of the total number of candidate frequency points as a frequency shift step of the target cell; determining the total number of candidate frequency points; determining all the candidate frequency points of the target cell; selecting one frequency point conforming to the preset condition from all the candidate frequency points as the working frequency point of the target cell. According to the technical scheme, the frequency shift step is dynamically changed according to the configured working frequency points of mutually-interfered neighboring cells, thereby allowing partial bandwidth between the cells to be overlapped, reducing the interference between the networks and improving the performance of the networks.

Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.

As shown in Figure 1, the embodiment of the present invention one determines the method for cell operation frequency, comprising:

Step 100, after frequency selection is carried out in trigger target community, according to the networking frequency range of Target cell and the frequency configured of relevant adjacent area, determines the span of candidate's frequency sum of Target cell;

Step 101, from meet candidate's frequency sum span frequency shift (FS) step-length select a frequency shift (FS) step-length as Target cell;

Step 102, according to the frequency shift (FS) step-length of Target cell, determines candidate's frequency sum;

Step 103, according to frequency shift (FS) step-length and the frequency sum of Target cell, determines all candidate's frequencies of Target cell;

Step 104, selects one and meets the working frequency points of pre-conditioned frequency as Target cell from all candidate's frequencies.

Preferably, after triggering frequency is selected, judge that whether networking bandwidth is equal with bandwidth of base station, if equal, then the working frequency points of community is the center frequency point of networking bandwidth; If unequal, then according to the networking frequency range of Target cell and the frequency configured of relevant adjacent area, determine the span of candidate's frequency sum of Target cell.

Preferably, according to the networking frequency range of Target cell and the frequency configured of relevant adjacent area, determine the span of candidate's frequency sum of Target cell, specifically comprise:

After frequency configuration is carried out in trigger target community, determine the frequency that relevant adjacent area has configured;

According to the frequency that relevant adjacent area has configured, judge the similarities and differences of the networking frequency range of Target cell and the networking frequency range of relevant adjacent area;

According to the similarities and differences of the networking frequency range of Target cell and the networking frequency range of relevant adjacent area, determine the span of candidate's frequency sum of Target cell.

Citing is described, if the frequency that relevant adjacent area has configured is 900MHz, 906MHz, the networking frequency range of Target cell is 900MHz ~ 910MHz, then the networking frequency range of Target cell is identical with the networking frequency range of relevant adjacent area, i.e. identical networking.If the networking frequency range of Target cell is 880MHz ~ 890MHz, then the networking frequency range of Target cell is different with the networking frequency range of relevant adjacent area, i.e. inter-frequency networking.

Preferably, if the networking frequency range of Target cell is identical with the networking frequency range of relevant adjacent area, then determine that relevant adjacent area has configured the number of frequency, and make candidate's frequency of Target cell sum be not less than the number that relevant adjacent area has configured frequency;

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

That is, when Target cell and relevant adjacent area identical networking, the sum of candidate's frequency of Target cell is more than or equal to the number that relevant adjacent area has configured frequency, and such as candidate's frequency of hypothetical target community adds up to N, the number that relevant adjacent area has configured frequency is M, then N >=M;

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

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

Preferably, the frequency shift (FS) step-length of Target cell and candidate's frequency sum meet following formula:

\{\begin{matrix} N &GreaterEqual; M; \\ N = \frac{(f_{high} - f_{low}) - W}{d} + 1 \\ d = \frac{d_{0}}{2^{j}}, i = 0,1,2, . . . . \end{matrix};

Specifically, determine exactly meet N>=M, frequency shift (FS) step-length d, according to the d determined, substitute into formula in obtain candidate's frequency sum N, value wherein due to the frequency shift (FS) step-length d determined by this method is not unique, preferably, from meet candidate's frequency sum span frequency shift (FS) step-length select maximum frequency shift (FS) step-length as the frequency shift (FS) step-length of described Target cell.

Wherein, initial frequency shift (FS) step-length d ₀, can determine according to different bandwidth of base station self adaptations.

Such as, d is advised ₀for the half of bandwidth of base station.When bandwidth of base station is 20MHz, then advise d ₀for 10MHz; When bandwidth of base station is 15MHz, then advise d ₀for 5MHz; Then advise d when bandwidth of base station is 10MHz ₀for 2.5MHz; When bandwidth of base station is 5MHz, then advise d ₀for 2MHz; When system bandwidth is 3MHz, then advise d ₀for 1.5MHz.

The value of frequency shift (FS) step-length d is positive integer.

When the value of the current frequency shift (FS) step-length d determined changes, upgrade current frequency shift (FS) step-length d.

In step 103, preferably, all candidate's frequencies of Target cell are determined according to following formula:

f_{l} = f_{low} + \frac{W}{2} + d * (l - 1), l = 1,2, . . ., N

Then from all candidate's frequencies, select one and meet the working frequency points of pre-conditioned frequency as described Target cell.

Preferably, step 104 specifically comprises:

Frequency solution sequence is formed by all candidate's frequencies;

Delete frequency that in frequency solution sequence, relevant adjacent area has configured and and the frequency that configured of relevant adjacent area between interval be less than the frequency of frequency shift (FS) step-length, obtain candidate's frequency solution sequence;

If determine candidate's frequency solution sequence not for empty, the frequency that between the frequency that working frequency points is and relevant adjacent area has configured of the Target cell then determined, the absolute value sum at interval is maximum, if exist multiple with the maximum corresponding frequency of the absolute value sum at interval between the frequency that relevant adjacent area has configured, then therefrom select a frequency as the working frequency points of Target cell;

If determine, candidate's frequency solution sequence is for empty, then the working frequency points of the Target cell determined is the frequency minimum with relevant adjacent area coherence, if the frequency minimum with relevant adjacent area coherence exists multiple, then therefrom selects a working frequency points as Target cell;

Wherein, according to the size of relevant adjacent area Reference Signal Received Power and/or determine the size with relevant adjacent area coherence with the distance of the base station spacing of relevant adjacent area.

Specifically, frequency solution sequence is f ₁, f ₂..., f _n, the frequency of relevant adjacent area is f ₅, f ₇, f ₉, and between the frequency that configured of relevant adjacent area, interval is less than the frequency of frequency shift (FS) step-length is f ₈, then candidate's frequency solution sequence is f ₁, f ₂, f ₃, f ₄, f ₆, f ₁₀..., f _n, from candidate's frequency solution sequence f ₁, f ₂, f ₃, f ₄, f ₆, f ₁₀..., f _nthe frequency that between the frequency selecting and relevant adjacent area to configure, the absolute value sum at interval is maximum.

Such as: frequency f ₁and the absolute value at interval between the frequency that relevant adjacent area has configured | f ₁-f ₅|+| f ₁-f ₇|+| f ₁-f ₉|, in like manner calculate f ₂, f ₃, f ₄, f ₆, f ₁₀..., f _n, draw and frequency that between frequency that relevant adjacent area has configured, the absolute value sum at interval is maximum.

If candidate's frequency solution sequence is empty, be then determine the working frequency points of Target cell with relevant adjacent area coherence according to the working frequency points of Target cell.

Wherein, adjacent area RSRP (Reference Signal Received Power, Reference Signal Received Power) is less, then less with the coherence of relevant adjacent area; Larger with the base station spacing of adjacent area, then less with the coherence of relevant adjacent area.

Wherein, prioritization rule is: from described frequency solution sequence first frequency, take preset value as step value, from frequency solution sequence, choose frequency and be arranged in order according to order from small to large and obtain the first frequency sequence, and the frequency selected is deleted from frequency solution sequence obtain the second frequency sequence;

2) the first frequency sequence f ₁, f ₃, f ₅, f ₁₉in maximum be f ₁₉, judge the second frequency sequence f ₂, f ₄, f ₆, f ₂₀in whether have and be greater than f ₁₉frequency, there is f ₂₀be greater than f ₁₉, then from f ₂₀start, from f ₂, f ₄, f ₆, f ₂₀select the frequency being spaced apart WMHz, be sequentially arranged in the first frequency sequence f from big to small ₁, f ₃, f ₅, f ₁₉f ₁₉after, due to f ₂, f ₄, f ₆, f ₂₀in do not have and f ₂₀be spaced apart the frequency of WMHz, then only by f ₂₀be placed in f ₁, f ₃, f ₅, f ₁₉obtain the 3rd frequency sequence f below ₁, f ₃, f ₅, f ₁₉, f ₂₀; Delete f ₂, f ₄, f ₆, f ₂₀in frequency f ₂₀, obtain the 4th frequency sequence f ₂, f ₄, f ₆, f ₁₈;

3) the 4th frequency sequence f is judged ₂, f ₄, f ₆, f ₁₈in whether there is f ₁, there is f in the point of+d ₂=f ₁+ d, then from f ₂start to select the frequency f being spaced apart WMHz ₂, f ₄, f ₆, f ₁₈, order from small to large adds the 3rd frequency sequence f successively to ₁, f ₃, f ₅, f ₁₉, f ₂₀below obtain f ₁, f ₃, f ₅, f ₁₉, f ₂₀, f ₂, f ₄, f ₆, f ₁₈, so far having completed frequency solution sequence is f ₁, f ₂..., f ₂₀whole sequences, obtain orderly frequency solution sequence f ₁, f ₃, f ₅, f ₁₉, f ₂₀, f ₂, f ₄, f ₆, f ₁₈;

If also there is unsorted frequency in the 4th frequency sequence, then continue to judge whether there is f in residue frequency ₁the frequency of+2*d, if do not exist, continues to judge whether there is f in residue frequency ₁the frequency of+3*d, if exist, from f ₁+ 2*d starts to select the frequency being spaced apart WMHz and comes from small to large after the 3rd frequency sequence that sequenced, then continues to judge whether to there is f ₁+ 3*d, until f ₁the value of+i*d is greater than the maximum frequency in unsorted frequency, then terminate to judge.

4) if also there is unsorted frequency in the 4th frequency sequence, then residue frequency is sequentially arranged in after above-mentioned the 3rd frequency sequence sequenced from small to large.

As preset value X > W, its sortord and aforesaid way similar, do not repeat them here.

If trigger base station configuration initialization frequency during opening base station, then using the working frequency points selected namely as base station current working frequency.

If in the process that base station is run, the frequency that the relevant adjacent area of monitoring base station has configured has renewal, then preferably, if the position of the current working frequency points of Target cell in orderly frequency solution sequence is after the working frequency points of the Target cell determined, then using the working frequency points of Target cell the determined current working frequency points as Target cell;

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

If the current working frequency points of Target cell is not in frequency solution sequence, then using the working frequency points of Target cell the determined current working frequency points as Target cell.

Specifically, if current working frequency is f ₅, at orderly frequency solution sequence f ₁, f ₃, f ₅, f ₁₉, f ₂₀, f ₂, f ₄, f ₆, f ₁₈in, if the working frequency points of the Target cell reconfigured is f ₁, then current working frequency points is updated to f ₁if the working frequency points of the Target cell reconfigured is f ₇, then current working frequency points is also f ₅if current working frequency is f ₀, not at orderly frequency solution sequence f ₁, f ₃, f ₅, f ₁₉, f ₂₀, f ₂, f ₄, f ₆, f ₁₈in, if the working frequency points of the Target cell reconfigured is f ₁, then current working frequency points is updated to f ₁.
