A policy control architecture and method for dynamically allocating policy servers to mobile devices is described herein. The policy control architecture introduces a new policy control element called the policy server control function. The policy server control function dynamically allocates policy servers to mobile subscribers when the mobile subscribers attach to an access network. In some embodiments, the policy server control function may also deallocate policy servers when mobile subscribers detach from all access networks to make the policy server resources available for other mobile devices.
