A macro wireless communication system includes a base station and a femto access point for communicating with user equipment (UE), such as handset, whereby the UE receives information regarding the network relationships between the base station and the femto access point. A home profile setting may be stored in the UE. When the UE communicates with a femto access point that is identified in the home profile, the UE adapts a neighbor listing provided by the home femto access point. Alternatively, the base station stores a list of the UE and its corresponding home femto access point, along with the neighbor list of the femto access point. When a UE is connected to the base station and that base station is in neighbor list of the UE's home femto access point, a message is sent to the UE to forward an appropriate neighbor list to simplify handovers.
