摘要： A time division multiplexed (TDM) communication system is disclosed, which apportions radio frequency communication channels into at least two time slots. Voice signals for transmission on this system are analyzed and vo-coded into a digital signal that is transmitted during one or more of the time slots. Received messages are recovered from at least one of these time slots and the voice message synthesized from the vo-coded signal. In this manner multiple voice messages may be transceived in a time division multiplexed manner on a single narrowband communication channel.

摘要： A digital radiotelephone system employs vocoders to convert between analog speech and a digital format suitable for transmission via radio. Under most circumstances, the highest data rate is selected for optimum audio quality. When the system occupancy exceeds a particular threshold, as detected at the fixed site of the system, some or all of the vocoders are instructed to switch to a lower data rate to provide for an increase in the number of communication channels. Further, a portable subscriber unit may autonomously change its vocoder data rate depending upon the charge state of its battery.

摘要： A method for interrupting a radio transmission in a quasi-duplex radio-frequency communication system. The method of the present invention includes the step of transmitting a signal (22), with periodically-occuring holes (24) therein, by a first communicatioin unit (10) to at least a second communication unit (12). The transmitted signal (12) includes an audio information portion (16) and information packets (23). Each information packet (23) specifies the time of occurence of the next hole (24). The second communication unit (12) initiates an interruption of the transmission made by the first communication unit (10) by transmitting an interrupt request signal (31) to the first communication unit (10) at a time specified by an information packet (23) received by the second communication unit (12). When the first communication unit (10) receives the interrupt request signal (31), it processes the interrupt request signal (23) to determine whether it complies with predetermined criteria. If the first communication unit determines that the interrupt request signal complies with the predetermined criteria, it transmits an acknowledgement signal allowing the second communication unit (12) to interrupt the transmission so that the second communication unit (12) may begin transmitting information to be received by at least the first communication unit (10).

摘要： A trunked radio subscriber requesting dispatch service transmits a request for a channel and immediately begins to speak without waiting to receive permission to access the channel. The subscriber radio locally records the information to be transmitted and, upon being assigned a channel, begins to reproduce and transmit the information. Recording and reproduction provides delay to span the time between request for and assignment to a channel and eliminates the need for the subscriber to wait to transmit or to quickly seize a channel assigned after an initial refusal. This enhances overall response time and increases time available for transmitting information signals. During interconnect calling, a trunked system alternately assigns inbound and outbound frequencies only as required for back-and-forth communication between simplex radio and duplex wireline subscribers. Voice buffering allows the parties to begin talking during the delay between request for and assignment of frequencies. The invention further provides for call origination by either radio or wireline subscribers without use of information channels. These procedures release resources and make them available to other callers.

摘要： A communications system central controller which regulates the access of a plurality of remote units to a single communications channel is disclosed. The central controller establishes a period of time wherein a remote unit may request service following the transmission of another remote unit. The central controller interprets the remote unit request for service, stores the request, and grants permission for the remote unit to transmit its message in accordance with the priority in the storage means. The grant of service is revoked by the central controller after a predetermined period of time following the conclusion of the remote unit transmission.

摘要： A communication unit (10) transmits a first signal (12) that has a plurality of holes (44) therein during the occurrence of which another communication unit may interrupt. A repeater (14) receives the first signal and transmits a second signal (16) comprising the information in the first signal, and a plurality of digital coded squelch words synchronized with the holes to indicate the location of at least one of the holes in the first signal (i.e., the time at which at least one of the holes will occur). In one embodiment, each hole occurs after each pair of coded squelch words, and accordingly the pairs of coded squelch words are marked to indicate the times of occurrence of holes in the first signal.
