摘要： Processing of dispatch calls in a simulcast multi-site communication system begins when a source communication unit transmits a message to one or more network receivers. The received signals are analyzed at the received sites to determine a signal quality metric. Each of the signals are time stamped to identify when they where received. The received signals are transported with their time stamp and signal quality metric to each of the other sites via a digital communication network connecting the sites. Each transmitter site performs a transmit operation by first determining the receiver source with the best quality signal as indicated by the signal quality metric. The determined best quality signal is stored until it is time to transmit the signal in phase with all the other transmitter sites in a simulcast manner. The time stamp allows a time in the future to be chosen to accommodate the worst case expected transport delay through the digital network.

摘要： Processing of dispatch calls in a simulcast multisite communication system (100) begins when a source communication unit transmits a message to one or more network receivers. The received signals are analyzed immediately at the received sites for signal quality (508). Each of the signals are time stamped (510) to identify when they were received. The signal quality is then compared to the signal quality of previously transmitted highest quality signals (514). If the signal quality is of higher quality than previously transmitted highest quality signals (516), the received signals are transported with their time stamp and signal quality metric to each of the other sites via a digital communication network connecting the sites (522). Each site now performs a transmit operation by first determining the receiver source with the highest quality signal as indicated by the signal quality metric (606). The determined highest quality signal is stored until it is time to transmit the signal in phase with all the other transmitter sites in a simulcast manner. The time stamp allows a time in the future to be chosen to accommodate the worst case expected transport delay through the digital network.

摘要： Determining transmit time of a received signal in a simulcast multi-site communication system begins when a communication unit transmits a message to one or more network receivers. The receivers transport the received signal with a time stamp to a master transceiver in the network via a digital communication network. The master transceiver then determines a launch time for transmission of a selected received signal, wherein the launch time is based on a previously executed procedure to determine the inbound and outbound delays in the simulcast multi-site communication system. Finally, the master transceiver transports the selected received signal with the launch time to other transceivers assigned to the call, wherein the transceivers transmit the selected received signal at the launch time.

摘要： Processing of message transmissions from any node in a simulcast multi-site communication system (100) begins when an initiating communication unit requests (400) to transmit a message to one or more network transceivers. After the request has been assigned by a call processing controller, the initiating unit transports (401) a time stamp message to each transceiver via a digital communication network (202). Each transceiver, after receiving the time stamp message, calculates (402) an outbound delay time and transports the outbound delay time to the initiating unit via the digital communication network. From the outbound delay time, the initiating unit calculates (406) a launch time, wherein the launch time accommodates the worst case expected transport delay through the digital communication network. The message to be transmitted and the launch time is transported to each of the transceivers, such that each transceiver simultaneously transmits the message at the launch time.
摘要翻译：当发起通信单元请求（400）向一个或多个网络收发器发送消息时，开始从联播多站点通信系统（100）中的任何节点处理消息传输。在由呼叫处理控制器分配请求之后，发起单元经由数字通信网络（202）向每个收发信机传送（401）时间戳消息。每个收发器在接收到时间戳消息之后，计算出（402）出站延迟时间，并经由数字通信网络将出站延迟时间传送到发起单元。从出站延迟时间起，启动单元计算（406）启动时间，其中启动时间适应通过数字通信网络的最坏情况下的预期传输延迟。要发送的消息和发射时间被传送到每个收发器，使得每个收发器在发射时同时发送消息。

摘要： Determining transmit time of a received signal in a simulcast multi-site communication system begins when a communication unit transmits a message to one or more network receivers. Each receiver transports the received signal with a time stamp to each transceiver in the network via a digital communication network. Each transceiver calculates a wait period, during which, the transceiver may receive the signal and time stamp message from another receiver. Once the wait period expires, each transceiver, using a substantially similar selection method, selects the same received signal to broadcast. Each transceiver then determines a launch time for transmission of the selected received signal, wherein the launch time accommodates the worst case expected transport delay through the digital network.

摘要： Alternate communication services may be provided in a communication system 100 based on the geographic location of a target communication unit. When a service request, which identifies the target communication unit and a particular service, is received by a communication resource controller (101), the communication resource controller (101) ascertains the location of a target communication unit and determines whether the target unit is located within a predefined area. If the target unit (102, 103) is located within the predefined area, the communication resource controller (101) determines whether the particular service requested is prohibited in the predefined area. If the service is prohibited, an alternate service is made available to the initiating communication unit.

摘要： A first communication device (18-22) provides a request for the establishment of a group communication to a communication infrastructure (12-14). The request includes a subject matter identifier and may further include a limitation identifier. Based on the subject matter identifier, and the limitation identifier, the communication infrastructure identifies at least one communication device. Having identified the at least one communication device, the communication infrastructure provides a response to the first communication device. The response identifies the at least one communication device and requests feedback as to whether the first communication device desires to establish the group communication with the identified at least one communication device. The first communication device then provides feedback to the communication infrastructure indicating how the group communication should be processed. Based on this feedback, the communication infrastructure processes the group communication.

摘要： A communication unit's estimated time of arrival at a target site may be determined when the location and velocity of the units has been ascertained. From this information (119), along with terrain information, an estimated time of arrival at a target site may be calculated. Having calculated the estimated time of arrival, this information is then transported to the communication units (102, 103) which is subsequently displayed to their operators.

摘要： An intelligent repeater (101) is used to control trunked communications at a trunked communication site in a trunked communications system. The intelligent repeator (101) transceives and signal processes radio frequency signals. The intelligent repeater (101) also processes and stores control information. The control information and processed signals are interfaced (109, 110, and 111) directly to an external communication network (117, 118, and 119), without use of a separate central controller for the trunked communication site or system.
