摘要： A switch that interconnects networks provides a scheduling algorithm that determines a number of active events to be processed by a processor in the switch. The active events involve processing of bearer traffic. A schedule tailored to the number of active events is generated. In response to a change affecting the schedule, the schedule is modified. The active events are processed by the processor according to the modified schedule.

摘要： An enhanced communication bridge includes a context interface that enables the audio bridge to learn information about the type of Voice encoder, device, network connection, location, type of call (business vs. personal), identity and position of the individual, and other information about the context of the communication session itself as well as the context of each person joining the communication session. This context information is used to determine how quality of experience targets for the communication as a whole, as well as how each individual contribution should be uniquely processed to attempt to meet the quality of experience targets. Business factors may influence the decision as to the type of processing to be implemented on each of the signals provided by the participants. Corrective action may also be implemented by the bridge on the client network devices as well in the embodiment. The bridge may be centralized or distributed. A video bridge may be implemented as well.

摘要： The present invention provides for echo cancellation circuitry and variable rate encoding circuitry to cooperate with one another to effectively provide comfort noise in an effective and efficient manner. The echo cancellation circuitry will use far-end signals to generate estimated echo signals, which correspond to the actual echo signals appearing in near-end signals. The estimated echo signals are essentially subtracted from the near-end signals in an effort to remove the actual echo signals from the near-end signals. The echo cancellation circuitry will monitor any residual echo signals in the resulting processed near-end signals and provide residual echo control signals that are indicative of whether the residual echo signals should be replaced with comfort noise. The residual echo control signals are used at least in part by the variable rate encoding circuitry to determine the encoding rate to use for encoding different portions of the processed near-end signals.

摘要： A conference bridge is provided for managing a conference between media signal sources generating media data packets conveying encoded media information and encoding type information. The media signal sources, in order to enter a conference, generate link messages including respective supported encoding types and transmit the link messages to the conference bridge. The conference bridge receives the link messages and processes them to derive a first common encoding type supported all media signal sources in the conference and a second encoding type supported a subset of media signal sources in the conference. The conference bridge generates link message reply signals conveying the first encoding type and the second encoding type the subset of media signal sources and conveying at least the first encoding type to the media signal sources other than the subset of all media signal sources. Each media signal source is responsive to the link message reply signal to render active at least the first encoding type and selectively render active the second encoding type.

摘要： In recent years, the telecommunications industry has witnessed the proliferation of a variety of digital vocoders in order to meet bandwidth demands of different wireline and wireless communication systems. The rapid growth in the diversity of networks and the number of users of such networks is increasing the number of instances where two vocoders are placed in tandem to serve a single connection. Such arrangements of low bit-rate codecs can degrade the quality of the transmitted speech. To overcome this problem in the specific situation involving store-and-forward systems (e.g. voicemail), the invention provides a novel method and apparatus including a plurality of different vocoders that can be selectively invoked to process the voice signal so as to reduce signal degradation. Also, the apparatus has the capability to bypass the vocoder bank when exchanging data with a remote signal processor capable of accepting data frames in compressed format.
摘要翻译：近年来，电讯业目睹了各种数字声码器的扩散，以满足不同有线和无线通讯系统的带宽需求。网络的多样性的快速增长和这种网络的用户数量正在增加两个声码器串联放置以服务于单个连接的情况的数量。低比特率编解码器的这种布置可能会降低发送语音的质量。为了在涉及存储转发系统（例如语音邮件）的具体情况下克服这个问题，本发明提供了一种新颖的方法和装置，其包括可以选择性地调用多个不同的声码器来处理语音信号，以便降低信号劣化。此外，当与能够接受压缩格式的数据帧的远程信号处理器交换数据时，该装置具有绕过声码器组的能力。

摘要： The present invention provides a novel system and a method for improving the voice quality of wireless-to-wireless calls or wireless-to-fixed terminal calls, while permitting a more efficient utilization of network resources. In a first aspect, the invention provides a communication system including a plurality of base stations connected to one another through a digital network (such as TDM, frame relay or ATM). Also, a plurality of vocoder channels, separate from the individual base stations, provide a data flow path from the base stations to wireline terminals first through the digital network via a Mobile Switching Center and finally through a landline network. In a wireless-to-wireless call, the compressed audio signal travels from one base station to another without undergoing any de-compression/compression. This avoids undesirable vocoder tandeming known to degrade voice quality. If the call is identified as being of a wireless-to-wireline terminal nature, the data is directed to a vocoder channel for decompression into PCM samples. The samples are then transmitted to the fixed terminal through the landline network. The main advantage of this network architecture is that fewer vocoders are required by comparison to prior art systems, therefore fewer costs are incurred. In addition, voice quality is improved.
摘要翻译：本发明提供了一种用于提高无线到无线呼叫或无线到固定终端呼叫的语音质量的新型系统和方法，同时允许更有效地利用网络资源。在第一方面，本发明提供一种包括通过数字网络（例如TDM，帧中继或ATM）彼此连接的多个基站的通信系统。此外，与各个基站分离的多个声码器信道提供从基站到有线终端的数据流路径，首先通过数字网络经由移动交换中心，最后通过陆线网络。在无线到无线呼叫中，压缩音频信号从一个基站传播到另一个基站，而不经历任何去压缩/压缩。这避免了已知降低语音质量的不良声码器串联。如果呼叫被识别为无线到有线终端的性质，则数据被引导到用于解压缩成PCM样本的声码器信道。样本然后通过陆线网络传输到固定终端。该网络架构的主要优点是与现有技术系统相比需要较少的声码器，因此产生较少的成本。此外，语音质量得到提高。
