Embodiment

[0107] Assumptions: 1), the research area is a 100 x 100 square coverage area;

[0108] 2), the coverage area is composed of 9 irregular cells with continuous coverage;

[0109] 3) The source of frequency sweep data is obtained according to the propagation attenuation model, which can be substituted by the actual frequency sweep data in further simulation;

[0110] 4), MR measurement report, estimated according to normal distribution with distribution interval [-15, 10].

[0111] Such as figure 2 Coverage areas of different base stations and cells in a certain coverage area shown:

[0112] According to the assumed conditions, the C / I distribution user data in the same cell in the mobile phone measurement report (MR) is continuously allocated and matched according to the C / I distribution of the frequency sweep data, and then the user group distribution of the target coverage area is obtained.

[0113] The three-dimensional view of user group distribution obtained after simu...

Abstract

The invention provides a frequency sweep and mobile phone measurement report-based method for automatic frequency optimization. The method specifically and efficiently grasps the improvement of wireless coverage quality on user groups from user group hierarchy, associative network quality and user awareness through the association and integration of frequency sweep data and mobile phone measurement report data so as to achieve a better balance among the user awareness, the network quality and various performance assessment indexes, reduce blindness and avoid fluctuations in network quality.

Description

technical field [0001] The invention belongs to the technical field of core networks in mobile communication networks, and relates to an autonomous frequency optimization method based on frequency scanning and mobile phone measurement reports. Background technique [0002] In GSM networks, frequency planning optimization directly affects network performance and user perception. Currently, there are three main technologies applied to GSM network frequency planning optimization: [0003] 1) Automatic frequency planning technology based on propagation model coverage prediction. [0004] 2) Automatic frequency optimization technology based on frequency sweep measurement statistics. [0005] 3) Automatic frequency optimization technology based on mobile phone measurement report (MR). For example, the application number is "2008100721495", the invention name is "Network Frequency Optimization Method Based on Measurement Report", the publication number is "CN101409884", and the ...
