  We present the extraction of the temperature by analyzing the charged
particle transverse momentum spectra in lead-lead (Pb-Pb) and proton-proton
(${\bf pp}$) collisions at LHC energies from the ALICE Collaboration using the
Color String Percolation Model (CSPM). From the measured energy density ${\bm
\varepsilon}$ and the temperature T the dimensionless quantity ${\bm
\varepsilon/}T^{4}$ is obtained to get the degrees of freedom (DOF), ${\bm
\varepsilon}/T^{4}$ = DOF ${ \pi^{2}}$/30.
  We observe for the first time a two-step behavior in the increase of DOF,
characteristic of deconfinement, above the hadronization temperature at
temperature $\sim$ 210 MeV for both Pb-Pb and ${\bf pp}$ collisions and a
sudden increase to the ideal gas value of $\sim $ 47 corresponding to three
quark flavors in the case of Pb-Pb collisions.
