Method and apparatus for evaluating network structure

Abstract

An embodiment of the invention provides a method and apparatus for evaluating a network structure. The method comprises the steps of acquiring sweep frequency data of each sweep frequency point; calculating the number N of available signal cells of each sweep frequency point and the total number M of auxiliary carriers of the available signal cells according to the sweep frequency data; calculating a co-frequency interference value between every two available signal cells based on the total number of the auxiliary carriers, correcting the co-frequency interference values by using the correlation of scrambling code groups, and obtaining interference values of the available signal cells; and calculating, according to the number N of available signal cells, the total number M of auxiliary carriers and the interference values of the available signal cells, a network structural index for evaluating the network structure. The network structural index is calculated based on the network overlapping coverage degree, the auxiliary carriers and the interference factors among the cells in a network, a quantitative analysis of a network status is achieved, and the larger the network structure index, more complex the network structure and the larger an optimized space.

Description

Technical field [0001] The present invention relates to mobile communication network technology, in particular to a method and device for evaluating network structure. Background technique [0002] Time Division-Synchronous Code Division Multiple Access (TD, Time Division-Synchronous Code Division Multiple Access) network overlap coverage, pilot pollution, high site configuration and intra-network interference are becoming more and more prominent. An effective evaluation method is urgently needed to find out the network structure for objective evaluation. The overall performance of the network. [0003] The current existing evaluation methods are limited to single-dimensional evaluation of several issues, presenting a single issue. [0004] The existing technology has the following problem: in the face of increasingly complex networks, single-dimensional evaluation of the overall performance of the network tends to lose sight of the other, and cannot meet the demand for obtaining th...
