摘要： A receiving device in a trunked radio communications system determines a transmit frequency, wherein the transmit frequency is calculated by subtracting a voice channel number from 559, multiplying by a channel spacing and adding a base frequency to yield the transmit frequency, if the voice channel number is between 559 and 320. The receiving device determines a receive frequency by 851.0250 MHz+[(559−a voice channel number)*12,500 Hz], if the voice channel number is between 559 and 320. In any case, the voice channel number is communicated in an outbound signaling message defined by Motorola's 3600-baud radio trunking protocol.

摘要： A receiving device in a trunked radio communications system requests a voice channel for a communication and receives an outbound signaling message on a control channel comprising a voice channel number for the receiving device to utilize for the communication. The receiving device tunes to about a transmit frequency, wherein the transmit frequency is determined by multiplying the voice channel number by a channel spacing and adding a base frequency to yield the transmit frequency, if the voice channel number is between 0 and 119. The receiving device modulates the communication to about the transmit frequency and transmits the modulated communication with a transmit deviation that relates to a maximum of 4 kHz.

摘要： A system and method for processing calls in a communication system utilizing distributed signaling. When a call signal having distributed identification data is received on a communication channel, the call information (such a voice, data, video, etc.) is initially passed through the system without verification until sufficient identification data (such as the color code) has been obtained to determine whether the source of the call is valid. Once sufficient identification data has been obtained, the source is verified. If the source is valid, the call information continues to be passed through the system. However, if source is invalid, the call information is blocked for the present call as well as for subsequent calls on the same communication channel, and passing of the call information through the system does not resume until a received call is subsequently assessed to be valid.

摘要： A system and method for interrupting a transmitting communication unit in a communication system. When a call is first initiated, the call is assigned to a communication channel and broadcast from a base site using the assigned communication channel. If it is determined that a transmitting communication unit should be interrupted, a zone controller signals a base site to generate an interrupt message. The base site generates an interrupt message containing an identification code for the transmitting communication unit and broadcasts the interrupt message on an outbound link of the communication channel. The transmitting communication unit, while transmitting on an inbound link of the communication channel, continuously monitors the outbound link. If the transmitting communication unit receives, on the outbound link, an interrupt message containing an identification code matching its own identification code, the transmitting communication unit stops transmitting.

摘要： In a two-way radio frequency (RF) communications system having at least one fixed terminal, one or more channels, and a plurality of subscriber units, the method comprising, a device receives, from a first subscriber unit, an alert tone request identifying at least a type of alert tone and at least one destination. In response, the device causes one or more fixed terminals corresponding to one or more radio sites associated with the destination identified in the alert tone request to instruct their subscriber units to play back a locally stored or generated alert tone corresponding at each subscriber unit. Receiving subscriber units then play back the alert tone on a continuous, periodic, or semi-periodic basis, selectively mixing the alert tone with call audio if present.
