We present preliminary results for the D_s meson spectroscopy study on the 2+1 flavour domain wall fermion lattice configurations, generated with the Iwasaki gauge action at beta=2.13 by the RBC-UKQCD collaboration. The simulations are on 16^3\times32 lattice with L_s=16. We consider the charm quark propagating as an overlap fermion at fixed lattice spacing. The dispersion relation and mass splittings are evaluated.
