There is disclosed, for use in a CDMA wireless network, a base station
capable of performing a soft handoff of a mobile station while the mobile
station is still in the process of first accessing the wireless network.
The base station comprises a receiver for receiving from the mobile
station a system access message that initiates in the wireless network a
system access procedure that establishes a communications channel between
the mobile station and the CDMA-based wireless network. The base station
also comprises a handoff controller, coupled to the receiver and receiving
the system access message therefrom. The handoff controller prepares
another selected base station in the CDMA-based wireless network to take
control over the system access procedure by sending a handoff control
message that initiates in the selected base station a handoff procedure
capable of assuming control over the system access procedure. This handoff
procedure is speculatively initiated in anticipation of a later handoff by
the mobile station.
