ABSTRACT:
A system, method, and device for a soft-hard handoff within a wireless telecommunications network are provided. The network may include a mobile station using a first carrier frequency for communication with a base transceiver station (BTS). The BTS may send a carrier frequency list to the mobile station that includes one or more carrier frequencies. The mobile station may include a carrier frequency searcher (CFS) that searches across the carrier frequencies to find a pilot signal having a strength greater than a threshold value. The mobile station may perform a soft-hard handoff by tuning itself to a second carrier frequency associated with the pilot signal. Subsequent communications involving the mobile station may use the second carrier frequency.
