摘要： Network access delays are minimized by using affiliation messages to pre-establish communications in a wireless communication network (100). In a first embodiment, connections between a site and a multicast server are not pre-assigned. A controller (102), upon receiving an affiliation message from a site (104), establishes connections between the site and a multicast server (111), the connections being uniquely associated with a talkgroup/site affiliation indicated by the affiliation message. In a second embodiment, connections between the site and the multicast server are pre-arranged. Thus, responsive to the affiliation message received from the site, the controller informs the multicast server that a talkgroup is affiliated with the site. Regardless of whether the first or second embodiment is used, the multicast server routes packetized information corresponding to the talkgroup to those sites with which the talkgroup is affiliated.

摘要： Network access delays are minimized by using affiliation messages to pre-establish communications in a wireless communication network (100). A controller (102), upon receiving an affiliation message from a first site (104), establishes connections between the first site and a second site (105), the connections being uniquely associated with a talkgroup/site affiliation indicated by the affiliation message. Additional sites can be added by modifying the connection to include the additional sites. Using a multicast SVC as the connection between the first and second site eliminates the need for a multicast server and its associated delays.
摘要翻译：通过使用附属消息来在无线通信网络（100）中预先建立通信来最小化网络接入延迟。控制器（102）在从第一站点（104）接收到附属消息时，建立第一站点和第二站点（105）之间的连接，该连接与由附属消息指示的通话组/站点归属单独关联。可以通过修改连接以添加其他站点来添加其他站点。使用多播SVC作为第一和第二站点之间的连接，消除了对多播服务器及其相关延迟的需要。

摘要： Listening capacity of a signal destination is augmented through the provision of a master switching center (207) and a slave switching center (209) linked via a dedicated communication port (203). Under direction of the master switching center (207), the slave switching center (209) sums communication system data signals received from shared communication ports (201) and presents the resulting summed communication data to the dedicated communication port (203). The master switching center (207) presents the summed communication data, received via the dedicated communication port (203), to the signal destination, thus augmenting listening capacity of the signal destination.

摘要： A radio console having a CRT display that allows channel control windows (CCWs) to be moved about a work area or from a summary list to a work area and back again. The CCWs may be of various sizes, and the display provides helpful indications of suitable locations to where selected windows may be moved. The display also allows preselected windows to be linked one to another, and to ensure that when one of the linked windows is moved, the remaining linked windows are moved in tandem with it. Also, if a window is manipulated to cause it to occlude an adjacent window, a distinct border is provided for the occluding window to indicate to the user that such occlusion heat occurred.

摘要： A communication system, console, and method of patching a PTT call are provided. An audio stream and control messages are provided to the console, which patches the either or both to target devices. The identity of the audio stream source is embedded only in the audio stream. Initially, when the audio stream is first patched, the identity is not provided. While the audio stream is being patched, the identity is extracted and the control messages updated so that the identity is immediately relayed through the console without having to wait for the next periodic transmission of a control message from the console.

摘要： A system and method for transmitting call information in a communication system having sites with long link delays. Upon a call being initiated within the communication system, a zone controller determines the participating sites that are to be involved in the call and assigns an IP multicast group address for the call. The zone controller also determines whether any of the participating sites have a long link delay. If any of the participating sites do have a long link delay, the zone controller also assigns an IP unicast address for each such site. The call information is then transmitted both on the IP multicast address as well as on each assigned IP unicast address to ensure that the call is received by each participating site without the loss of call information.

摘要： A method of call control in a packet-based communication system having consoles, distributed among one or more console sites, that are adapted to monitor talkgroup calls. The console sites are served by console site links having a limited available bandwidth. Upon receiving a request for a talkgroup call, there is identified a number of priority consoles requesting participation in a talkgroup call. For example, the priority consoles (or console operators) may indicate that monitoring of the talkgroup call is “critical” for those consoles. Based on the location of the priority consoles, a number of priority console sites are identified for the talkgroup call. If sufficient bandwidth (e.g., call units of bandwidth) is available (or made available) to each of the priority console sites, the call is granted. Alternatively or additionally, the call may be granted to certain non-priority console sites if bandwidth is available. Bandwidth may be made available for critical talkgroups at certain sites by pre-empting non-critical talkgroups being monitored at those sites.

摘要： An automatic level control system is described for use with a voice processor which generates an AGC control signal to vary the gain applied to an audio input signal. The system includes a dynamically adjusting peak detector for detecting noise peaks and voice peaks while ignoring voice lulls which occur after a voice peak. Detected peaks are processed by an improved voice/noise sensor which develops a first output signal when voice is detected and a second output signal in the absence of detected voice. These output signals are received by a gain control circuit which is adapted to prevent the AGC control signal from increasing system gain for an indefinite interval in response to the second signal, and to permit normal variation in the AGC control signal in response to the first signal.
摘要翻译：描述了一种与产生AGC控制信号以改变施加到音频输入信号的增益的语音处理器一起使用的自动电平控制系统。该系统包括一个动态调整的峰值检测器，用于检测噪声峰值和声音峰值，同时忽略在语音峰值之后发生的语音滞后。检测到的峰值由改进的语音/噪声传感器处理，其在检测到语音时产生第一输出信号，并且在没有检测到的声音的情况下产生第二输出信号。这些输出信号由增益控制电路接收，该增益控制电路适于防止AGC控制信号响应于第二信号而增加系统增益以达到无限间隔，并且响应于第一信号而允许AGC控制信号的正常变化。
