    • The invention provides a system, method and apparatus for controlling a mass calling event in a VoIP network. The invention provides for monitoring port traffic information on a network edge device and detecting the occurrence of a mass calling event in conjunction with a call control module. Control instructions or information may then be provisioned to network edge devices to alleviate congestion. The invention enables network edge devices to gap or provide other controls to reduce call overloading. Controls for alleviating congestion include blocking the packets, providing an announcement to the call, re-routing the traffic associated with this specific mass calling event, and reducing the quality of the service.
    • 本发明提供一种用于控制VoIP网络中的大规模呼叫事件的系统,方法和装置。 本发明提供了一种监视网络边缘设备上的端口流量信息,并结合呼叫控制模块检测质量呼叫事件的发生。 然后可以将控制指令或信息提供给网络边缘设备以减轻拥塞。 本发明允许网络边缘设备间隙或提供其他控制以减少呼叫超载。 用于缓解拥塞的控制包括阻塞分组,向呼叫通知,重新路由与该特定大规模呼叫事件相关联的流量,以及降低服务质量。
