Motivation

Future networks will continue to support voice services and objective assessment of conversational speech quality in networks will continue to be enhanced, but it is not sufficient just to be able to measure multimedia network performance objectively. Rather, when the objectively measured results indicate that an unsatisfactory level of impairment exists, it is highly desirable if algorithms can be developed to determine the cause of the impairments in networks and terminals irrespective of which media are involved.

Question

The Question is intended to derive a framework for diagnostic functions and to provide guidance how diagnostic functions can be triggered from external objective quality predicting models in networks and terminals - irrespective of the type and number of media involved.

Study items to be considered:

• Identify the media related parameters that could be subject to diagnostics
• Provide guidance on inter-relations between such parameters
• Develop a strategy that can use from the outputs of external objective predicting media quality for the purpose of determining the root cause of a specific problem with a connection.
• What enhancements to existing Recommendations are required to provide energy savings directly or indirectly in Information and Communication Technologies (ICTs) or in other industries? What enhancements to developing new Recommendations are required to provide such energy savings?

Tasks

Tasks include, but are not limited to:

• Develop one or more Recommendation(s) to provide guidance on interaction between diagnostic functions and external objective models.
• Develop one or more new Recommendation(s) providing guidance for the implementation of diagnostic functions.
• Specification of requirements for algorithms that can be used for diagnostic functions.
