Abstract

The present application describes embodiments of a method and apparatus for determining handover parameters in a wireless overlay network. One embodiment includes modifying a bias value used to determine when to handover user equipment between a macrocell and a femtocell that overlays the macrocell. The bias value is modified in response to a change in one or more handover frequencies associated with the user equipment. Handovers of user equipment are triggered when a sum of the bias value and a measured value of the femtocell signal strength exceed a measured value of the macrocell signal strength.
