摘要： Methods and systems for femto-cell identification are disclosed herein. In one embodiment, a femto-cell base station is adapted to transmit with each broadcast a value which maps one-to-one to a different portion of a femto-cell identification. After the mobile station reports each broadcasted value to the serving non-femto-cell, the target femto-cell identification can be determined by combining multiple reports. In this manner, a fairly large identification space can be provided without significant increases in implementation complexity. In some embodiments, the system does not introduce issues with backward compatibility since standard cell identification procedures are preserved. In some embodiments, knowledge of the maximum number of femto-cells within a non-femto-cell is not required, thereby preventing ambiguous hand-in targets.
