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: The present invention discloses a method, a node, and a monitoring center for detecting a network fault and relates to the field of network communications. The method includes: when a node receives a voice stream, receiving a source identifier, a codec type, and voice quality parameters; acquiring, according to the codec type and the voice quality parameters, a fault score corresponding to the node; and detecting, according to the fault score corresponding to the node, whether a network fault occurs on a network between the node and a source corresponding to the source identifier. The monitoring center includes: a first receiving module, a first acquiring module, and a first detecting module; and the node includes: a second acquiring module, a third acquiring module, and a second detecting module. In the present invention, a network fault that occurs on a network can be detected in time.
