Heterogeneous networks are consisted of the networks with different Radio Access Technologies (RAT). Vertical handoffs would be triggered while mobile users moving across two cells implemented different RATs during the session. Thus, some serious problems will be caused due to characteristics of different RATs. Numerous solutions have been proposed to solve these problems. However, most of existing solutions only take into account single traffic, e.g. Vertical HandOffs (VHO). In this paper, an analytical model is proposed, with which VHO is taken into account, but also New Services (NS).
