Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment among the present invention, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work should belong to the scope of protection of the invention.
Fig. 1 shows the schematic diagram according to the group network system of the shared BCCH frequency of the embodiment of the invention.As shown in Figure 1, this group network system comprises:
At least three group of base stations, a described group of base stations is made of at least two base stations, and identical BCCH frequency is used in all base stations in each described group of base stations, and adjacent group of base stations is used different BCCH frequencies;
Described base station at least one base station controller, described base station controller and described group of base stations communicates.
In embodiments of the present invention, by primordial station, a plurality of base station group, a plurality of group of base stations are used different BCCH frequencies, the saving of maximum magnitude the BCCH frequency, simultaneously because the use in a wider context of identical BCCH frequency has further realized reducing with the effect of frequency with adjacent interference frequently.
As shown in Figure 1, this system comprises at least three group of base stations, group of base stations is not a kind of independent network equipment, group of base stations is to be made of a plurality of base stations, is a kind of grouping that carry out a plurality of base stations is divided, and each group of base stations how many base stations is made of, the effect of the saving BCCH frequency that depends on existing BCCH frequency resource quantity and need reach, there is a serious shortage in the supply for BCCH frequency resource, or need under the situation of the more BCCH of saving frequency, and then each group of base stations is made up of more base station; BCCH frequency resource is deficient relatively, maybe needs to save under the situation of less BCCH frequency, and then each group of base stations is made up of less base station.
