Abstract: Embodiments of the present invention disclose a method, a network element, and a system for assessing voice quality, which relates to the communications field and solves a problem that user perception cannot be reflected according to a voice quality assessment result. The method includes acquiring a voice code stream, and collecting statistics on a transmission parameter in each short-time assessment period; decoding the voice code stream, and collecting statistics on a source parameter according to the decoded voice code stream; and calculating a comprehensive voice quality assessment result according the transmission parameter and the source parameter. The present invention is used for voice quality assessment.

Abstract: Embodiments of the present invention provide a method and device for service analysis. The method for service analysis of the present invention includes obtaining deep packet inspection DPI information of a terminal, where the DPI information of the terminal is obtained by performing DPI on a first data packet transmitted between the terminal and a service provider; obtaining call history record CHR information of the terminal, where the CHR information of the terminal is obtained by performing call recording on an air interface link established between the terminal and a base station controller; and performing, according to the DPI information of the terminal and the CHR information of the terminal, analysis on a service transmitted between the terminal and the service provider.
Abstract translation: 本发明的实施例提供了一种用于服务分析的方法和装置。 本发明的服务分析方法包括获取终端的深度分组检查DPI信息，其中通过在终端和服务提供商之间发送的第一数据分组执行DPI来获得终端的DPI信息; 通过在终端和基站控制器之间建立的空中接口链路上执行呼叫记录，获得终端的CHR信息，从而获得终端的呼叫历史记录CHR信息; 根据终端的DPI信息和终端的CHR信息，对终端与服务提供者之间发送的服务进行分析。
