We derived a meson mass equation and revealed a specific new behaviour of the mass-dependent strong coupling $\\hat\\alpha_s(M)$ defined in the time-like region. A new infrared freezing point $\\hat\\alpha_s(0)=1.03198$ at origin has been found and it did not depend on the confinement scale $\\Lambda>0$.
