QUALITY OF EXPERIENCE DETERMINATION FOR MULTI-PARTY VOIP CONFERENCE CALLS THAT ACCOUNT FOR FOCUS DEGRADATION EFFECTS

摘要

In one embodiment, the quality of experience for a multi-part conference call is determined. Values for network characteristics for a conference call between at least three parties is captured using a multi-party conference call system. The network characteristics encompasses at least parameters expressed in an E-Model R-Factor equation. A quality of experience (QoE) is determined that accounts for degradation effects. The determined QoE is represented as a corrected mean opinion score (MOS) perceived by the receiving party. A controllable parameter of the conference call is dynamically and automatically modified to positively affect the determined QoE of the receiving party when the QoS is below a designated minimal QoE threshold.
