A method and device for allocating frequency points for cells

Abstract

An embodiment of the present invention provides a method and device for allocating frequency points for a cell. The method includes: drawing a dotted distribution map according to the location of the cell, where a point in the dotted distribution map corresponds to a cell; triangulating the dotted distribution map Divide to form a triangular network, determine the interference influence range of each cell according to the triangular network; calculate the interference distance, frequency point demand and sparring interference of each cell in the triangular network according to the interference influence range; according to the interference distance, frequency point demand Determine the difficulty allocation factor of each cell according to the interference with sparring, and allocate frequency points to the cell in the order of difficulty allocation factors from large to small. According to the location of the cell, a planar point distribution map is drawn, and a triangular network is formed on the basis of the point distribution map, and the number of frequency points required, the distance from the adjacent cell, and the azimuth angle are obtained according to the interference influence range, and the azimuth angle fight relationship is reduced. The frequency point interference between local parts of the network can also reduce the global interference degree of the network.

Description

technical field [0001] The invention relates to mobile communication network technology, in particular to a method and device for allocating frequency points for cells. Background technique [0002] Planning frequency resources is an important link in the planning of mobile communication networks. Failure in frequency planning will result in poor performance indicators after the entire network is built or expanded. During a call, it will be interfered by the same frequency of adjacent cells, resulting in a good reception level but poor reception quality, and in severe cases, calls will be dropped. In the process of GSM frequency planning and optimization, frequency multiplexing methods include packet multiplexing, dynamic multiplexing, multiple frequency multiplexing (MRP), intelligent multi-layer frequency multiplexing, etc. Different frequency planning can be selected according to the layout of base stations in different regions Or optimization methods, but any frequency ...
