The mechanism behind ferromagnetic exchange interaction in GdN is not well understood. It has been argued that it can be due to fourth order cross process of \textit{d-f} mixing and \textit{d-f} exchange. An alternative explanation suggests an anti- ferromagnetic interaction between Gd \textit{d} and N \textit{p} induced moments on the rock salt structure which aligns the nearest neighbor Gd \textit{f} moments ferromagnetically through the \textit{d-f} exchange. In this paper we present results of Curie temperature in GdN as a function of carrier density calculated within our multiband modified RKKY- like exchange interaction. It includes realistic bandstructure of the 5\textit{d} conduction band as an input for single particle energies. We analyze the possibility of carrier- mediated ferromagnetism in GdN and also demonstrate a simple phenomenological model which justifies the role of charge carriers.
