Problems solved by technology

[0004] However, when the distribution of small base stations in the network is too dense, the interference inside the network will be seriously enhanced, and the coverage performance of the network will be adversely affected.
It can be seen that blindly increasing the deployment density of small base stations does not help much in improving network coverage performance, but instead increases network deployment costs.

Abstract

The invention discloses a method and apparatus for outputting network coverage performance evaluation reference. The method comprises the following steps: determining expected deployment density of base stations; and outputting the distribution of average coverage probabilities of a mobile terminal under the expected deployment density to serve as coverage performance evaluation references of networks obtained according to the expected deployment density according to the expected deployment density, a probability distribution model of a first distance and a communication quality model of the mobile terminal, wherein the first distance is the distance between the mobile terminal and a closest target base station, the average coverage probabilities of the mobile terminal under the expected deployment density are average values of probabilities in which the obtained communication quality is greater than a first preset value after the mobile terminal accesses the closest target base station under the expected deployment density. By adoption of the method and apparatus, the relationship between the network coverage performance and the base station deployment density can be obtained, and thus guidance can be provided for determining the reasonable deployment density of the base stations.

Description

technical field [0001] The present application relates to the technical field of mobile communication, in particular to a method and device for outputting network coverage performance evaluation basis. Background technique [0002] With the popularization and intelligentization of mobile terminals, the demand for mobile communication of mobile terminals also increases sharply. In order to meet the increasing demand for mobile communications, operators will deploy more base stations in the network to improve the coverage performance of the network. Deployed base stations often include macro base stations. Although macro base stations have the characteristics of large capacity and strong coverage performance, operators cannot blindly increase the number of macro base stations due to the disadvantages of large volume, special equipment room required for deployment, troublesome installation and construction, and high deployment costs. Improve network coverage performance. [...
