Abstract
The power of a first signal is measured and is compared with a threshold. If the first signal power meets a handoff threshold, the system enters the handoff procedure. Once in the handoff procedure, estimates of a first signal quality a signal would have, if transmitted from the first site to the subscriber, and a second signal quality a signal would have, if transmitted from the second site to the subscriber, are determined. If the estimated first signal quality meets a transmit threshold, the first will activate a traffic signal to the subscriber. If the estimated first or second signal quality fails to meet the transmit threshold, the first or second, respectively, will terminate its traffic signal to the subscriber, but the transmission resources will remain dedicated to the subscriber. If the estimated first or second signal quality fails to meet the handoff threshold, the first or second, respectively, will discontinue serving the subscriber.
