Abstract

The invention provides a frequency optimization method by adding leakage-configuration adjacent cells based on grid positioning. The method comprises the following steps: receiving measure reports (MR); performing longitude and latitude positioning on the MR, and configuring virtual adjacent cells by combining preset-range-divided grids; constructing a virtual interference matrix through the virtual adjacent cells; fusing an actual interference matrix constructed by current network actual adjacent cells and the virtual interference matrix to form a new interference matrix; obtaining cell interference degree and frequency interference degree by performing calculation based on the new interference matrix, and performing performance evaluation on the cell interference degree and frequency interference to obtain suggested frequency points; and performing frequency optimization based on the suggested frequency points. The frequency optimization method is more perfect, and the frequency optimization method is more accurate; and meanwhile, the independence and autonomy of the frequency optimization method are improved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a frequency optimization method for adding missing adjacent cells based on grid positioning. Background technique [0002] In mobile communication, the carrier-to-interference ratio (C / I) is used to evaluate the interference situation of the network. Its meaning refers to the ratio of the received desired signal level to the undesired signal level. It is divided into co-channel interference protection ratio and adjacent frequency interference protection ratio. Co-channel interference protection ratio: refers to the interference caused by another cell to the serving cell when different cells use the same frequency, and their ratio is generally required to be >=9 in the specification; the adjacent-channel interference protection ratio refers to the interference between the frequency In the case of multiplexing, adjacent channels will interfere with the channel used by the s...
