Method and system for optimizing wireless network

Abstract

The invention provides a method and system for optimizing a wireless network. The method comprises the steps of: counting cell pairs which have a frequency restriction relationship in the wireless network; obtaining connected clusters in the wireless network, wherein the connected clusters are cell sets of the wireless network and the frequency restriction relationship exists between any two cells in the cell sets; respectively obtaining the maximum connected cluster of each cell in the wireless network, wherein the maximum connected cluster is the connected cluster containing the maximum number of carrier waves in the connected clusters containing the cell; selecting the maximum connected cluster, containing the carrier waves with the number greater than the threshold of the number of carrier waves, from all the maximum connected clusters to obtain a connected cluster to be optimized; and carrying out coverage optimization and / or capacity optimization on the cells in the connected cluster to be optimized. By means of the method and the system for optimizing the wireless network, the three-dimensional equilibrium optimization of the coverage, the capacity and frequency interference of the wireless network are realized and the overall quality of the wireless network can be effectively promoted.

Description

technical field [0001] The invention belongs to the field of mobile communication, in particular to a wireless network optimization method and system. Background technique [0002] The goal of wireless network optimization is to construct an "ideal network", that is, to achieve a balanced and reasonable level in coverage, capacity, quality and other aspects, so as to achieve the optimal level of the overall network. Existing technologies evaluate and optimize wireless networks from a single dimension. [0003] 1. Existing wireless network coverage evaluation and optimization methods [0004] Reasonable cell coverage is the foundation of a high-quality network and the basic factor affecting capacity and quality. Ideally, at a certain point, the terminal can measure no more than three serving cells, and the signal strength between serving cells has a clear gradient distribution. There must be a cell with strong signal strength as the main serving cell. Unreasonable coverage...

Problems solved by technology

However, coverage, capacity, and frequency interference are closely related and affect each other and restrict each other. A single evaluation and optimization method can easily lead to reasonable performance in one dimension, but unsatisfactory performance in other dimensions; or a cell achieves an ideal state, but Imbalances in which surrounding communities are negatively affected
