Abstract The problem of nonlinear Schrödinger soliton interaction with an oscillating impurity is considered. The regimes of soliton motion for the cases of periodic and random oscillations of the impurity near an equilibrium point are investigated. As shown in the first case there exist regions of parameters under which a soliton dynamics becomes chaotic. The comparison of statistic characteristics of chaos in the region of dynamic and standard stochasticity is carried out. The coefficient of the soliton diffusion is found.
