Summary: In this document, we present the plan for the integration of variable stars into the Besançon Galactic model used in the Gaia simulator. It is based on the knowledge of the fraction of variables within a certain stellar population for a given variability type (i.e. in a certain HR diagram region), and on a modelling which consists of a set of probability distributions of periods and amplitudes with an associated light curve model.
