Table 1 Relation between \(R\)-value, MOS and subjective quality (adapted from [21])
From: A semantic approach for QoS specification of communication services using QoE parameters
\(R\)-value | MOS | Subjective quality |
|---|---|---|
\(\ge \)90 | \(\ge \)4.34 | Best |
\(\ge \)80 | \(\ge \)4.03 | High |
\(\ge \)70 | \(\ge \)3.60 | Medium |
\(\ge \)60 | \(\ge \)3.10 | Low |
