| 1. A method of determining initial position information for a mobile station comprising:
receiving amplified modified signals from the mobile station, wherein the amplified modified signals from the mobile station
include a discriminant applied by a sub-regional repeater in communication with the mobile station, the sub-regional repeater
configured to apply the discriminant and transmit the signal from the mobile station with little or no amplification to a
regional repeater configured to amplify the modified signals;
accessing position information of the sub-regional repeater using the discriminant; and
determining the initial position information for the mobile station using the position information of the sub-region repeater.
