Embodiment Construction

[0073] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0074] In frequency optimization, if there is certain traffic in the overlapping coverage area of ​​two cells, and the signal strength difference between the two cells is within 9dB or -9dB, then the two cells should avoid co-frequency or Adjacent frequency, and these two cells are referred to as a cell pair with a frequency restriction relationship. Such as figure 1 As shown, if a cell has a frequency restriction relationship with another cell, connect them with a connection line, and connect all the cells with frequency restriction relations with a connection line, thus forming a graph.

[0075] A connected cluster is defined, and there is a frequency restriction relationship between any two cells in the cluster (that is, they are connected by a ...

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...
