1. A CDMA wireless communications system that controls the initial power and data rate settings during forward link establishment of a traffic channel comprising:

  • a base station controller;

    one or more base stations that report a current forward link load estimate to the base station controller; and

    a mobile station that reports a received pilot channel signal-to-noise ratio to the base station controller, wherein the base station controller sets the number of traffic channel connections and the data rate to be allocated for the traffic channel connections, computes a target traffic channel signal-to-noise ratio based on the data rate and the number of traffic channel connections, and computes the initial traffic channel power based on estimated forward link channel characteristics, the target traffic channel received signal-to-noise ratio, the base stations'"'"' load, the number of traffic channel connections, and the traffic channel data rate.
