The invention discloses an assessment method and apparatus for a frequency planning scheme to solve the problem that an assessment method for a frequency planning scheme in the prior art cannot provide a quantified assessment of the merits of the frequency planning scheme. The assessment method comprises obtaining a maximum communication cluster of individual cells of a whole network, and calculating a frequency interference factor of the maximum communication cluster; obtaining the function relationship between the frequency interference factor and the corresponding number of carriers based on the frequency interference factor; and assessing the frequency conversion gain of a first planning scheme over a second planning scheme based on function relationship. Through the above technical scheme, the degree of improvement of the frequency scheme on adjacent channel interferences can be quantitatively assessed on the basis of a current network structure, and adjacent channel interferences caused by improper frequency arrangement and due to no frequency optimization space resulted from irrational network structure can be distinguished, so that more targeted frequency optimization can be conducted.
Description
technical field [0001] The present invention relates to the field of wireless network planning and optimization, and more specifically, to a method and device for evaluating a frequency planning scheme based on a wireless network structure. Background technique [0002] Frequency resources are limited and precious resources in wireless communication systems. With a certain network structure, avoiding co-adjacent frequency interference as much as possible through reasonable frequency planning is conducive to fully improving frequency utilization and providing an optimal network with limited frequency resources. capacity. As the GSM network develops to a mature stage, the complexity of the network structure is increasing day by day, and the difficulty of frequency planning is increasing. It is usually necessary to complete the optimization and adjustment of the network structure before the overall frequency conversion optimization, such as reducing over-coverage, reducing high...
