Abstract
A system, method, and computer readable medium for handoff of a user equipment from a macrocellular system to a femtocell system is provided. A micro-pilot assisted handoff routine may be implemented to facilitate handoff of a user equipment from a macrocellular system to a femtocell system. The femtocell system may transmit very low power pilot, paging, and synch channels on a common frequency used by the macrocellular system. In another embodiment, a mobile assisted handoff routine facilitates handoff of a user equipment from a macrocellular system to a femtocell system. The user equipment's preferred roaming list includes an entry for the femtocell system and specifies a SID/NID and pseudo-noise offset for the femtocell system. The user equipment is configured to periodically enter a search mode to attempt to locate the femtocell system by switching to a femto carrier that is specified in the preferred roaming list.
