This paper discusses load balancing in cellular networks. It compares the performance of both static and dynamic allocation policies for a simple model of two base stations with overlapping cells. In particular, it investigates the performance of the policy obtained by the first step of the policy iteration algorithm (FPI policy). When starting with a static policy, the two base stations can be modeled independently as Erlang loss systems, for which the relative costs can be easily, determine in each state. This makes the first step of the policy iteration algorithm of low complexity, and therefore applicable for large instances. The idea is to approximate the optimal policy with the FPI policy. Numerical experiments for small instances provide a deeper understanding of the FPI policy.
