Embodiment Construction

[0024] The implementation manner of the present invention will be described in detail below in conjunction with the traditional three-sector solution.

[0025] Figure 1 is a distribution diagram of the interference situation of the traditional three-sector networking scheme. Taking 19 cells as an example for analysis, as shown in the figure, the filled part in the figure indicates that the frequency of the channel resources in the three-sector structure is the same as that of the reference sector 100 In this architecture, co-channel interference is an important factor restricting system throughput. Interference analysis of sector 100 shows that because the antenna has directivity, there are seven interference sources on the left side of sector 100, and the strongest interference is the grid with the closest distance Two sectors 102, 103 are filled, followed by five sectors 101, 104 to 107 filled with diagonal lines.

[0026] After the present invention is applied to the three...

Abstract

A channel resource distributing method and device of a cellular system are disclosed in the present invention, wherein, the method comprises: step one, to divide the channel resource in each sector of cellular system cell into multiple according the frequency spectrum, and to lead each channel resource to have priority for deciding using order; step two, in the sectors of each cell existing co-frequency interference, by setting the priority, to lead each sector existing co-frequency interference to use firstly the channel resource with different frequency to the interference cell. The present invention fractionizes the channel resources in the vectors, effectively avoiding the co-frequency interference. The priority of the channel resource is pre-established, and solidified in configuration of the cell sector, needless to calculate real time, the method is simple and easy, and the cost is lower.

Description

technical field [0001] The invention relates to mobile communication cellular networking technology, in particular to a method and device for channel resource allocation of a cellular system. Background technique [0002] For mobile communication networks, people have been using a cellular structure for cell networking for a long time. For cellular networking, there are currently a variety of solutions, mainly including dynamic networking and static networking. Dynamic networking is to dynamically allocate frequency resources between cells according to the load and interference conditions of each cell. Dynamic networking technology is complicated. The degree is high, and the cost is also high. Static networking is more representative: soft frequency multiplexing networking, central multiplexing as 1 and edge multiplexing as 3 networking, three-sector networking, etc. At present, there are many studies on the three-sector networking scheme , and is widely used. Although th...
