Soft handover of a mobile unit is facilitated on a wireless network from
base station to base station. The network can employ multi-channel
receivers to receive signals from mobile units within range, including
mobile units assigned to neighboring base stations. Information
associated with received signals, such as an indication of their signal
strength, can be relayed to a central location for assessing whether the
mobile unit should be assigned to another base station, and implement
reassignment of one or more mobile units based on such assessment. Soft
handover reduces dropped calls when the connection from mobile to base
station is unexpectedly lost. The second BTS can add a carrier to
communicate with the mobile unit and provides the mobile unit with the
necessary parameters, such as frequency and time slot data, to complete
the handover or the connection can be established through a variety of
contingency plans.
