In cellular networks, base station must reserve some resource for the possible handoff which affects the energy efficiency of the system. In this paper, the authors establish a theoretical model to maximizing the Energy Efficiency (EE) from the aspects of users' mobility and service duration. After analyzing the probability of handoff in service with user mobility and service characteristics, they introduce a Dynamic Energy Efficiency (DEE) function. With the DEE function, an optimization problem under the constraint of maximal power is formulated to determine the optimal cell radius to maximize the DEE. They prove the existence of the unique optimal cell radius and propose an algorithm to solve the problem.
