  • Patent number: 7424297
    Abstract: Disclosed are a soft handoff system, a soft handoff method, and a mobile terminal equipped with the soft handoff system. The soft handoff system for a mobile terminal analyzes periodically monitored wireless conditions of neighbor base stations, transmits a PSMM (Pilot Strength Measurement Message) to a current base station when a condition arises that needs reporting to the current base station, and performs handoff operation by allocating/releasing wireless resources to/from a suitable base station according to an HDM (Handoff Direction Message) received from the current base station, wherein upon receiving the HDM from the current base station, the system allows a handoff drop timer of an active base station belonging to an active set having a pilot channel signal strength less than a predetermined value to continue running rather than to be reset until the handoff drop timer expires.
