We predict the effect of the charm structure function on the longitudinalstructure function at small x. In NLO analysis we find that the hard Pomeronbehavior gives a good description of $F_{L}$ and $F^{c}_{k}$ (k = 2,L) at smallx values. We conclude that a direct relation between $F_{L}/F^{c}_{2}$ wouldprovide useful information on how to measure longitudinal structure function athigh $Q^{2}$ values. Having checked that this model gives a good description ofthe data, when compared with other models.
