In these proceedings we discuss the measurement of Bose-Einstein momentum correlation function of pairs of charged hadrons in PbPb collisions at 5.02 TeV. We describe the measured correlations with correlation functions derived from Levy type source distributions. Using a transverse momentum and centrality binning, we extract the correlation strength parameter lambda, Levy index alpha and Levy scale parameter R as a function of pair transverse mass mT, for various centralities.
