Method for optimizing neighbor cell plan based on topological structure

Abstract

The invention provides a method for optimizing a neighbor cell plan based on a topological structure. The method comprises the steps of acquiring working parameter information of each system, wherein the working parameter information at least comprises geographic information and cell direction angle information; computing a distance between a cell and a neighbor cell, included angles among cells and a ligature, an included angle of the cell, and an included angle of the neighbor cell, according to the geographic information and cell direction angle information; according to site types, performing neighbor cell addition aiming at three situations such as a neighbor cell between macro sites, a neighbor cell between a macro site and an indoor distribution system, and a neighbor cell between indoor distribution systems; and thus obtaining optimization results of plans of the neighbor cells between macro sites, between a macro site and an indoor distribution system, and between indoor distribution systems, and outputting optimization schemes for plans of the neighbor cells in the systems and between the systems. The method can be effectively applied to planning the neighbor cells between the macro sites and between the indoor distribution systems, and planning and optimizing the neighbor cells in the systems and between the systems; according to the neighbor cell algorithm, only engineering parameter information needs to be provided, and reasonable neighbor cell plan optimization information is selected according to multiple factors such as the geographic environment, wireless environment and base station distribution.

Description

Technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method for planning and optimizing neighboring cells based on a topology structure, which can be applied to the neighboring cell planning of newly-built cells, and can also be used to optimize existing cells. Background technique [0002] Regardless of whether the mobile terminal is in the standby state or talking state, it will receive the identification of the neighboring cell and the corresponding frequency information periodically issued by the current serving cell, and measure the strength of the BCCH frequency or the dominant frequency of the neighboring cell based on the received information , To determine whether it is necessary to switch to a neighboring cell with better service quality. For each cell (which may be referred to as a source cell), the neighboring cell of the cell may be referred to as the neighboring cell of the cell for short. As the mo...

Problems solved by technology

[0007] (2) The situation of neighboring cells between systems is not considered, so it cannot be applied to the planning and optimization of neighboring cells between systems

In the actual network situation, due to the differences in geographical environment, wireless environment and base station construction distribution, it is difficult for the fixed-value topology algorithm to be universal and targeted.

In the topology optimization algorithm of the prior art, the upper and lower limits of the range considered by neighboring cells are fixed, and there is no self-adaptability, so good optimization results cannot be obtained for different wireless environments
