A 2G + 4G mobile network voice quality joint evaluation method and device

Abstract

The embodiment of the invention provides a 2G + 4G mobile network voice quality joint evaluation method and device. The method comprises the steps of obtaining performance file data reported by a 2G base station access server and a 4G base station access server; Preprocessing the acquired performance file data to generate a multi-dimensional database; Comparing the multi-dimensional database withvarious data in a pre-established association database, and enabling a comparison result to correspond to an MOS value in the association database; Based on grids with 2G and 4G telephone traffic simultaneously, clustering comparison results according to the positions of the grids and 2G + 4G voice connection numbers in the grids to obtain L regions with high 2G + 4G service telephone traffic, andrecording the L regions as P; And clustering the L regions of the P to obtain an evaluation result of the average opinion MOS value of each region of the L regions of the P so as to obtain the MOS value distribution state of the whole grid region. According to the embodiment of the invention, evaluation of the voice quality of the 2G + 4G mobile network can be realized.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a method and device for jointly evaluating voice quality of a 2G+4G mobile network. Background technique [0002] With the continuous development of mobile communication technology, the second, third and fourth generation mobile communication technologies (2G, 3G, 4G) coexist in the network of operators. Voice service is the core and basic service of mobile communication network, and its quality evaluation is an important criterion for measuring network performance. Among the existing mobile network voice services, 2G voice services, 3G CS (circuit switched) domain, and 4G volte can all provide voice services. However, in the process of network construction and maintenance, how to evaluate and build the network to ensure the quality of voice services, It's a complicated and ineffective thing. [0003] The voice quality evaluation in the p...
