1. A method to operate a mobile station to detect an incoming call, comprising:
at the mobile station, simultaneously demodulating signals from a digital paging channel DPCH from individual ones of N base stations using a plurality of fingers, where N is greater than one;
soft combining the outputs of those fingers that receive the DPCH from an individual one of the N base stations and storing the combined soft outputs in an individual one of N buffers;
separately decoding the content of each of the N buffers to determine if a page signifying the incoming call to the mobile station was received from at least one of the N base stations; and
if a page was received, determining, prior to initiating a network access procedure, which one of the at least one base stations to use when initiating the network access procedure.
