摘要： A method is disclosed that enables an improved technique for recovering from an error scenario encountered during a call setup involving a malfunctioning media gateway and corresponding media gateway controller. The media gateway first detects a malfunction that affects a digital signal processing resource, and then proactively selects a processing resource available elsewhere at the gateway. The media gateway selects the new processing resource based on criteria including: i) the capabilities that were identified to handle the packet stream at the affected (faulty) processor; ii) the capabilities of the IP terminal originating the packet stream that is being moved; and iii) the Internet Protocol address of the affected processing resource. Advantageously, an effort is made to avoid having to inform the media gateway controller of the move, thereby minimizing any discontinuity in each packet stream and minimizing the time and processing that are required to establish the call.

摘要： A method is disclosed that enables a media gateway controller to optimize the selection of a media gateway from which to acquire call-related resources, in a multi-gateway environment. In accordance with the illustrative embodiment, the controller sets a high utilization threshold and a low utilization threshold for each media gateway it controls, for the purpose of receiving a notification when a threshold is crossed. As resources are utilized, removed from service, or become available for use, the media gateway recalculates the resource utilization of one or more predetermined resources and notifies the controller if a threshold for a particular resource has been crossed. The controller, in turn, uses the current threshold states as part of the selection of media gateway to serve one or more subsequent calls. The disclosed method can increase the probability of selecting a media gateway with sufficient resources for a successful call completion on the first attempt.
摘要翻译：公开了一种使多媒体网关控制器能够在多网关环境中优化从其获取呼叫相关资源的媒体网关的选择的方法。根据说明性实施例，为了在跨越阈值时接收通知的目的，控制器为其控制的每个媒体网关设置高利用率阈值和低利用率阈值。当资源被利用，从服务中移除或可以使用时，媒体网关重新计算一个或多个预定资源的资源利用率，并通知控制器是否已经跨过特定资源的阈值。控制器又使用当前阈值状态作为媒体网关的选择的一部分来服务于一个或多个后续呼叫。所公开的方法可以增加在具有足够资源的情况下选择媒体网关的可能性，以便在第一次尝试时成功呼叫完成。

摘要： A method is disclosed that enables accelerating the removal from service of a signal processor at a media gateway. In accordance with the illustrative embodiment of the present invention, the media gateway receives an indication to remove one of its digital signal processors from service. Instead of waiting for all of the calls that are using the signal processor to come to an end, the media gateway proactively moves the packet streams from the signal processor to one or more other signal processors resident at the gateway. Advantageously, an effort is made to avoid having to inform the corresponding media gateway controller of the move, thereby minimizing any discontinuity in each moved packet stream.
摘要翻译：公开了一种能够加速从媒体网关处的信号处理器的服务移除的方法。根据本发明的说明性实施例，媒体网关接收从其服务中移除其数字信号处理器之一的指示。媒体网关不是等待使用信号处理器的所有呼叫结束，而是主动地将分组流从信号处理器移动到驻留在网关处的一个或多个其他信号处理器。有利地，努力避免必须通知相应的媒体网关控制器移动，从而最小化每个移动的分组流中的任何不连续性。
