摘要： A system and method for receiving data and control messages comprised of a series of data units is provided. The data units comprising each message are structured to follow a particular sequence, such as zero or more data units of a first type followed by one or more data units of a second type, which may then followed by data units of one or more other predetermined types. Upon receiving a data unit of a first or second type, a number of “units to follow” is determined from information provided in the received data unit. A number of subsequently received data units are then forced to be processed as one of the first type, the second type, or other predetermined type in accordance with the known structure of the message. The number of subsequently received data units that are forced to be processed as one of these types is based on the determined number of units to follow.

摘要： An expandable text messaging service protocol for use with a two-way radio transceiver includes an extension bit field for creating an expandable header for controlling the overall size of data packets used for communicating message traffic. The protocol further includes a control bit field for designing the message as a control message or user message and a protocol data unit (PDU) type field for identifying the message type. A payload field may further be used for carrying message content.

摘要： A received synchronization pattern is compared against first and second known synchronization patterns. If the received pattern is of the first known pattern, the payload is processed as voice; and if the received pattern is of the second known pattern, the payload is processed as non-voice. In an alternative, the received pattern is compared against first and second known synchronization patterns. If the received pattern is of the first known pattern, a first operating mode is selected, and if the received pattern is of the second known pattern, a second operating mode is selected.

摘要： Symbol recovery for multi-level digital signals has traditionally been difficult because of the nature of the eye pattern output by the discriminator (103), and especially its response to a noisy or impeded signal environment. This method and apparatus for recovery thresholds adjusts (411 and 417) to the current state of the discriminator (103) output of the received signal, based on an attenuated (301) version of that signal. Using a fast adjust mode and slow adjust mode, the threshold generating circuitry (331 and 361) adapts to the signal based on data from the received signal fed into lock detectors (329 and 359) which determine the mode to use.

摘要： A method and apparatus for confirming delivery of group data to a plurality of radio communication devices in a wireless communication system. The wireless communication system includes a plurality of radio communication devices in communication with a sender. In operation, the sender sends group data to the plurality of radio communication devices and further determines a call hang time sufficient to contain a dedicated acknowledgment slot for each of the plurality of radio communication devices. The sender reserves an acknowledgment slot in the determined call hang time for each radio communication device and further sends an acknowledgment polling signal to each radio communication device, where the acknowledgment polling signal identifies the respective acknowledgment slot that is reserved for each radio communication device to acknowledge receipt of the group data. The sender accordingly receives an acknowledgment from the radio communication devices during its respective reserved acknowledgment slot.

摘要： In a two-way radio frequency (RF) communications system having at least one repeater, a plurality of channels, and a plurality of subscriber units, a repeater hosts a first channel that is currently serving as a rest channel. The channel that is currently serving as the rest channel is monitored by subscriber units that are idle in the system. When the repeater determines to select a second channel to serve as the rest channel, it determines whether there is at least one eligible channel to serve as the rest channel. If there is at least one eligible channel in the system, the repeater may select the second channel to serve as the rest channel from one of the eligible channels.

摘要： In operation, a transmitting device selects a synchronization pattern associated with the desired timeslot that is at least mutually exclusive from synchronization patterns associated with other timeslots on the same frequency in the system. Once selected, the transmitting device transmits a burst embedding the synchronization pattern that was selected, where appropriate. If the receiving device detects the synchronization pattern, it immediately synchronizes with the timeslot with confidence that it is synchronizing to the desired timeslot by using sets of synchronization patterns associated with the desired timeslot that are at least mutually exclusive from synchronization patterns associated with the other timeslots on the same frequency.

摘要： Within a two way radio frequency communication system, a repeater transmits an identity of a rest channel when transmitting during an active communication call on a channel other than the rest channel. A subscriber unit communicating within the active communication, receives the identity of the rest channel, leaves the active communication; and initiates a new communication on the rest channel.
