TECHNIQUES FOR ACCESSING A WIRELESS COMMUNICATION SYSTEMWITH TUNE-AWAY CAPABILITYTo access a first communication system, a terminal determines a transmission time for anaccess probe, an expected response time from the system, and a protected time intervalbased on the transmission time and/or expected response time. The terminal determines astarting time for sending the access probe such that the protected time interval does notoverlap a tune-away interval in which the terminal is to monitor anther frequency/air-interface. This starting time may be set initially to the end of a prior access probe plus apseudo-random wait duration and may be advanced forward or moved backward in time,if needed, by a time duration selected such that the protected time interval does notoverlap the tune-away interval.Figure 8
