Abstract:
1. In a time division multiple access (TDMA) system having a plurality of timeslots, a method comprising the steps of: tuning to a frequency in the system; searching for a desired set of synchronization patterns on the frequency, each of at least two slots on the frequency out of n slots used on the frequency having a set of synchronization patterns that are mutually exclusive of each other and of other sets of synchronization patterns used in the system on the frequency, and including at least a first set of synchronization patterns identifying a rest timeslot and a second set of synchronization patterns identifying a non-rest timeslot, the rest timeslot (or channel) being a channel identified in the system as one which idle subscriber units within the system monitor for transmission of at least one new call initiation and new rest channel notification; and if one of the synchronization patterns belonging to the desired set of synchronization patterns is detected on the frequency, synchronizing to a timeslot in which the synchronization pattern was detected and receiving information corresponding to the rest or non-rest timeslot.
