摘要： Methods of communicating location information from a subscriber to a repeater are described. The subscriber switches from a working channel to a data revert channel, transmits a request for a periodic or one-time window to transmit an update, and determines from grant information in the response announcement the allocated window and frame before switching back to the working channel. Before the allocated time, the subscriber switches to the data revert channel, confirms whether it remains scheduled to transmit the update from a repeater announcement, and if so transmits the location update in either the current or reserved window. The announcements from the repeater contain the identity of the next window and frame and the subscriber reserved to use the window in addition to grant information. The subscribers may or may not be time-aligned and the data and data revert channels may or may not be synchronized.

摘要： A method for facilitating transmission of data in a communication system (100) is provided herein. In operation, a base radio of a plurality of base radios (105-n) combines status information corresponding to a plurality of inbound frequencies and transmits the combined status information on a single outbound radio frequency. Further, each of the plurality of inbound radio frequencies corresponds to one of the plurality of base radios. Then, one or more radio terminals (110-n) monitor the single outbound radio frequency to receive the combined status information, determine at least one available inbound radio frequency from the plurality of inbound radio frequencies based on the received combined status information, selects an inbound radio frequency of the at least one available inbound frequency, and transmits the data using the selected inbound radio frequency to the corresponding base radio.

摘要： A system and method for interrupting a transmitting device during a call. In the system, calls are transmitted from a first device on a communication channel as a series of channel frames. At predetermined times during the transmission, the transmitting device is configured to drop channel frames, resulting in open channel frame periods where the transmitting device is not transmitting on the communication channel. During these open channel frame periods, the transmitting device is also configured to switch to a receiving mode. Other devices in the system are capable of switching into a transmitting mode during the open channel frame periods and, when applicable, sending an interrupt request on the communication channel to the transmitting device in order to request access to the channel.

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.

摘要： A subscriber unit monitors a first channel currently serving as a rest channel for the system, wherein the channel currently serving as the rest channel for the system is monitored by subscribers that are idle in the system. The subscriber unit determines that a first call is being initiated on the first channel. If the first call is not of interest, the subscriber unit ceases to monitor the first channel, and monitors a second channel that will serve as the rest channel for the system when the first call starts on the first channel. If the first call is of interest, the subscriber unit participates in the first call on the first channel, and before or after the first call ends, participates in a second call on a third channel or monitors a channel currently serving as the rest channel for the system when the subscriber unit becomes idle.

摘要： The time required for the receiving device to synchronize to a desired timeslot is reduced. 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. Using synchronization pattern associated with the desired timeslot that is at least mutually exclusive from synchronization patterns associated with the other timeslots on the same frequency also improves spectral efficiency in direct-mode transmissions, thus allowing more than one subscriber unit to simultaneously transmit in direct mode on a frequency without interfering with other transmissions on the frequency.
摘要翻译：接收设备与期望时隙同步所需的时间减少。在操作中，发送设备选择与期望时隙相关联的同步模式，该期望时隙至少与系统中相同频率上与其他时隙相关联的同步模式相互排斥。一旦选择，发送装置在适当的情况下发送嵌入所选择的同步模式的突发。如果接收设备检测到同步模式，则它立即与时隙同步，使其与期望的时隙同步。使用与期望时隙相关联的同步模式，其至少与同一频率上的其他时隙相关联的同步模式互斥，也提高了直接模式传输中的频谱效率，从而允许多个用户单元以直接模式同时发送一个频率，而不会干扰频率上的其他传输。

摘要： The present invention discloses, 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 receives a message that identifies a channel that is selected to serve as a rest channel for the system. The channel that is currently serving as the rest channel for the system is monitored by subscriber units that are idle in the system. If the repeater determines that the channel selected to serve as the rest channel is hosted by the repeater, the repeater periodically transmits an identity of the channel as the channel currently serving as the rest channel on at least the channel.

摘要： A transmitting device encrypts DMR voice superframes using encryption parameters and sends (300) the encryption parameters in at least one of the voice superframes by: identifying (302) a selected number of bits from a plurality of vocoder frames the voice superframe; replacing (304) each of the identified bits with a corresponding bit of a first encryption parameter; placing (306) at least one encryption parameter in an embedded signaling field of the voice superframe; and transmitting (308) the voice superframe with the encryption parameters to a receiving device. The receiving device extracts the encryption parameters, which can be a key identifier, an algorithm identifier, and an initialization vector for use in decrypting messages from the transmitting device.
