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.

Method, network element, and system for assessing voice quality

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.
