Power Control is necessary for efficient operation in a CDMA system. Information transmitted in the System Access state is of bursty nature and there is no scope of power control since the MS is not set-up on a dedicated link with the BS. Hence in this case the power control in use is the Open Loop power control.
The basis of this power control is setting up the mobile with parameters that make it transmit at intervals, which prevent collisions from other mobiles by using a hash equation (which has minimum collisions). The hash equation uses some general parameters received in the Access Parameters message (APM) and parameters, which are unique to the mobile.

It is used as power,timing and phase reference for BTS to detect signal transmitted on the reverse link.

During system access state,power control bits during transmission of an EAch or RCCch,serving as power,timing and phase reference for BTS to detect signal transmitted on the reverse link.
