or derivative standards the mobile station may suspend or disable the forward fade timer that might otherwise cause the mobile station to return to system determination the reason for this is that in general the mobile station may want to monitor one or more secondary base stations that it can barely receive a signal from this can still be useful because all that may be needed is some of the location related information it is not necessary to maintain reliable or usable communications with secondary sectors there are several possibilities in terms of when during the time that the mobile is not monitoring its assigned slot s that the mobile may monitor other sectors fig5 shows the case where the mobile station monitors secondary sectors immediately after the assigned slots monitoring of secondary sectors may also be performed at some point during the period that the mobile station would otherwise be sleeping monitoring of the secondary sectors may be done periodically every pre determined number of slots for example or the mobile station could monitor a subset of secondary sectors each slot the mobile station may alternatively monitor the secondary sectors just before its assigned slot the mobile may search for pilot channels while monitoring the secondary sector s and thereby be well prepared.
