Abstract: The present invention provides a method of minimizing synchronization delay in a radiotelephone system between a modular subscriber cluster communicating with a common base station, the modular subscriber cluster receiving repetitive time slots from the base station and having a plurality of frequency-agile modems, the method comprising the steps of: synchronizing a selected one of the modems to a selected time slot of the received time slots; generating a frame sync signal from said selected modem; and distributing said frame sync signal to remaining ones of the plurality of modems.

Abstract: A power-conserving time division multiple access (TDMA) radiotelephone system is disclosed in which a cluster of subscriber stations, remote from a base station, employs a common pool of frequency-agile modems each of which digitally synthesizes, on a time slot-by-time slot basis, the different channel-identifying intermediate needed to support communications between several of the subscriber stations and the base station. Power conservation is facilitated inter alia by controlling the assignment of modems to calls, maintaining unassigned modems in a powered-down state and by controlling the number of calls using the same time slot. Delay in assigning a powered-down modem to a call is eliminated by making available to all modems the highest quality synchronization information obtained by any of the active modems.

Abstract: The invention relates to a method for hierarchically assigning of time slots in a radiotelephone system including a central base station, a plurality of remote subscriber stations, means defining a repetitive set of time slots meant for supporting radiotelephone calls between said subscriber stations and said central base station, a group of modems, each of said modems being capable of handling a plurality of said telephone calls on said time slots, which comprises the stages of : ascertaining the active modems having idle time slots; assigning preference ratings to said idle time slots of said group of modems; ascertaining which of said time slot has the highest of said preference ratings, assigning the time slot corresponding to said highest preference rating ascertained to the next one of said calls.
