Abstract

The invention discloses a 3G voice service quality evaluation method based on data mining and belongs to the field of the communication technology. According to the method, a voice quality evaluation model of a 3G wireless communication network is obtained according to the relation between a voice quality value and uplink wireless link network parameters and the relation between the voice quality value and downlink wireless link network parameters through a data mining method, wherein data required by model training are obtained from a signaling monitoring platform of a current network; network physical layer parameters provided by the signaling monitoring platform are input in the real-time evaluation process after the model is established, original voice samples are not needed, real-time monitoring can be conducted on voice service quality, influences of wireless links on voice quality are reflected in the transmission process of a mobile communication network, the influences are the condition of the mobile network where users are located, reasons for voice quality reduction can be quickly located, and consequently a reference is provided for targeted network optimization.

Description

technical field [0001] The invention relates to a voice service quality evaluation scheme in a mobile communication system, in particular to an objective evaluation algorithm based on data mining and capable of real-time monitoring of voice service quality in a third-generation mobile communication system (3G), belonging to the field of communication technology . Background technique [0002] With the continuous development of mobile communication systems, operators can provide more and more services, in addition to traditional voice services, it also includes diversified data services (for example, video streaming, online games, download services, etc.), And the proportion of data services continues to increase. However, among many services, the voice service is still the most basic and important service, and the average revenue per user (ARPU) of the voice service is still an important part of the overall ARPU value. High-quality voice services help to improve users' rec...
