摘要： Methods and systems are provided for selecting a low-cost Internet base station (LCIB) for a macro-network-to-LCIB handoff of an active mobile station. In one embodiment, a handoff request is received from a mobile station, the handoff request indicating that the mobile station is requesting that a first pseudorandom number (PN) offset be added to an active set for the mobile station, the active set comprising one or more macro-network sectors. It is determined that the first PN offset is associated with an LCIB pilot beacon, and a candidate set of LCIBs is responsively identified, the candidate set consisting of substantially all of the LCIBs that are located in the one or more macro-network sectors in the active set. It is determined whether the mobile station is an authorized mobile station of exactly one LCIB in the candidate set and, if so, the mobile station is directed to handoff to that LCIB.
