Below by taking Fig. 8 a and Fig. 8 b as an example, scheme provided in an embodiment of the present invention is illustrated.

In Fig. 8 a, left part determines frequency band schematic diagram before the 3rd frequency band, and cell01 is first community in figure, cell02 For second community, first band partly overlaps with second band, and right part determines the frequency band schematic diagram after the 3rd frequency band, from figure In it can be seen that, the 3rd frequency band and second band are non-overlapping.In Fig. 8 b, left part is the position of first band and second band Schematic diagram, first band partly overlaps with second band in figure, and right part is that base station determines the 3rd frequency band in first community, From the figure, it can be seen that the 3rd frequency band and the lap of second band are less than the lap of first band and second band.

Alternatively, in the embodiment of the present invention, determining the concrete mode of the 3rd frequency band can be：With all frequencies of first community The center of band is symmetric points, and the frequency band full symmetric with first band is defined as into the 3rd frequency band, or, with first band The first area at place or the center of second area are symmetric points, and the frequency band full symmetric with first band is defined as into Three frequency bands.Certainly, in other embodiments of the present invention, only it need to meet that the 3rd frequency band and second band are non-overlapping, or, the 3rd frequency band It is less than the requirement of the lap of first band and second band with the lap of second band, other manner can also be used Determine the 3rd frequency band.

S505：First terminal is dispatched on a third band in base station.

Alternatively, in embodiments of the present invention, as shown in fig. 7, this method can also include：

S506：Terminate the scheduling to first terminal on the first band of frequencies in base station.

The step can perform after step s 505, can also judge the frequency band profit of first community and second community Preset value is respectively less than with rate and first band partly overlaps with second band and performed afterwards.

This method provided in an embodiment of the present invention, when first band and second band partly overlap, detection can also be passed through The actual band efficiency of cell in base station, it is adjusted to dispatching the position of frequency band of first terminal, so that proper first When the interference type of terminal is weak jamming, it is that strongly disturbing terminal is disturbed to reduce by interference type in second community, or, When the interference type of first terminal is strong jamming, reduces and done to caused by interference type in second community for the terminal of weak jamming Disturb.Therefore, the edge customer that this method can be reduced externally for weak jamming in directional base station is disturbed by adjacent area, improves It is externally the handling capacity of the edge customer of weak jamming in directional base station.

Alternatively, in embodiments of the present invention, in step S503, judged result is first band and second band part When overlapping, this method can also include：

Base station determines the 4th frequency band in second community, and second terminal is dispatched in base station on the 4th frequency band.

In the embodiment shown in fig. 7, in the case where first community and second community have idle frequency band, in first community The frequency band that the lap of interior searching and second band is less than the lap of first band and second band is whole to dispatch first End.Alternatively, in embodiments of the present invention, the 4th frequency band, the 4th frequency band and first band can also be found in second community It is non-overlapping, or, the 4th frequency band and the lap of first band be less than the lap of first band and second band.Equally may be used To realize when the interference type of first terminal is weak jamming, reduce and disturbed by second community, or, when first terminal When interference type is strong jamming, the interference to caused by second community is reduced.

Alternatively, when second terminal is being dispatched in base station on the 4th frequency band, this method can also include：Terminate base station To the scheduling of second terminal on two frequency bands.

As step S506, terminate the scheduling to second terminal over a second frequency band, can both start in base station the Second terminal is dispatched on four frequency bands to perform afterwards, can also be small in the band efficiency for judging first community and second community It is carried out after preset value and first band partly overlap with second band.

This method provided by the invention, can also be by detecting in base station when first band and second band partly overlap The actual band efficiency of cell, it is adjusted to dispatching the position of frequency band of second terminal.Therefore, this method equally can be with Reduce the edge customer being located in directional base station externally for weak jamming to be disturbed by adjacent area, improve in directional base station externally to be weak The handling capacity of the edge customer of interference.

In still another embodiment of the process, when including third terminal in second community, third terminal and first terminal Interference type is identical, and the 5th frequency band is base station when the frequency band of third terminal is dispatched in second community, as shown in figure 9, the party Method can also include：

S701：Base station obtains the band efficiency of first community and second community.

S702：Base station judges whether the band efficiency of first community and second community is respectively less than preset value.When respectively less than During preset value, S703 is carried out, otherwise, is terminated.

S703：Base station judges whether first band partly overlaps or completely overlapped with the 5th frequency band.When first band and the When five band portions are overlapping or completely overlapped, S704 is performed, otherwise, is terminated.

In other embodiments of the present invention, S703 can also be first carried out, then perform step S701, or, step S701 and Step S703 can be performed simultaneously.As long as meet that the band efficiency of first community and second community is respectively less than preset value and first Frequency band and the 5th band portion are overlapping or completely overlapped, it is possible to perform 704.

S704：Base station determines the 6th frequency band in whole frequency bands of first community.

6th frequency band and the 5th frequency band are non-overlapping, or, and the lap of the 6th frequency band and the 5th frequency band be less than first frequency The lap of band and the 5th frequency band.

In embodiments of the present invention, the mode of the 6th frequency band is determined, may refer to the mode of the above-mentioned frequency band of determination the 3rd, This is repeated no more.
