Abstract
A femto cell neighbor list message for a wireless communication system that includes the frequencies and pseudonoise offsets reserved for macro cells and femto cells is disclosed. When the user equipment discovers the femto cell, the user equipment can read the Femto Cell Identification Message and present the identification information to the subscriber. In absence of this knowledge, a manual femto cell search must search all frequencies and all pseudonoise offsets resulting in lengthy search times.
