Methods, systems, and devices are described that may provide for femtocells to indicate the proximity of mobile user equipments and/or provide mobile identity to assist in resolving femtocell disambiguation. A femtocell may detect a user equipment in its proximity using an out-of-band link. The femtocell may transmit a proximity indication message to a macro network controller via a core network. The macro network may direct the user equipment to perform a variety of tasks, including directing the user equipment to do a handover to the femtocell. Some embodiments may utilize existing user equipment registrations and femto-to-macrocell outbound handover procedures to address problems such as femtocell ambiguity resolution and triggering frequency searches at a macro network when a current macrocell signal strength is good. These embodiments may utilize dummy identifiers to register the user equipment to facilitate addressing these problems.
