摘要： A method for interrupting active communications within a communication network, the method comprising in one embodiment: operating a communication device to terminate communication activity in response to receiving an interrupt request from an interrupting device; operating a repeater to wake up and initiate message communication activity in response to receiving a base station downlink activation message from the interrupting device; and operating the interrupting device to transmit one or more messages on a receive frequency of the repeater. The method for interrupting active communications within a communication network comprising in an alternate embodiment: operating a repeater, in response to receiving an interrupt request from an interrupting device, to clear each channel hosted by the repeater: informing the interrupting device by the repeater that all channels have been cleared; de-keying the repeater; operating the interrupting device to transmit one or more communications on a transmission frequency of the repeater.

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： 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： Disclosed is a method of automatic establishment of a location-based talk group call with reduced messaging overhead. The initiating device may be a subscriber unit (SU). The SU determines a geographic reference location and generates location data representative of the location. The SU broadcasts a location-based talk group call header including the location data and including a location-based talk group call identifier field set to cause other SUs receiving the call header to receive and output subsequent data associated with the call header responsive to determining that its current geographic location satisfies the location criterion of the call. The location criterion may be fully determined by the initiating SU and specified in the call header, and may take the form of a specified radius that extends from the geographic reference location represented in the call header.

摘要： Disclosed are methods and systems for compressing location data of a radio for over-the-air transmission. A method includes obtaining raw latitude and raw longitude coordinates reflecting a current location of the client device, the raw latitude coordinate represented by x number of bits and the raw longitude coordinate represented by y number of bits. The raw latitude coordinate is truncated by removing n number of most significant bits from the raw latitude coordinate to create a compressed latitude coordinate. The raw longitude coordinate is truncated by removing m number of most significant bits from the raw longitude coordinate to create a compressed longitude coordinate, where m varies as a function of the value of the raw latitude coordinate. The compressed longitude and compressed latitude coordinates are then transmitted to another network device for decompression and use as an indication of the client device's absolute location.

摘要： A method for facilitating transmission of data in a communication system is provided herein. In operation, a base radio of a plurality of base radios 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 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 transmitting the data using the selected inbound radio frequency to the corresponding base radio.

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： 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.
