Abstract	In Carrier Cloud, the on-demand edification of a carrier-grade mobile network on the cloud in an elastic way provides a flexible network thanks to the Network Functions Virtualization (NFV). It allows using cloud computing infrastructure, instead of having custom hardware appliances for each network function, and setting up a mobile, flexible, dynamic, and rapidly deployable network. These features provide to the network the programmability and flexibility that makes it able to dynamically adapt to changing user's mobility and demand. Among these NFVs are the Serving Gateway (S-GW) and Packet Data Network Gateway (PDN-GW or P-GW), which must be positioned effectively in order to respond to changes and behaviors of the user, on the one hand, and services, on the other hand. Our contribution is to propose a solution to define dynamically S-GW and P-GW positions in given datacenters, based on Constraint Satisfaction Problem (CSP) and an improved version of Forward Checking, in order to ensure the automatic adaptation to the requirements of users and services.
