    • A method for adaptively improving voice quality during a communication session includes monitoring voice quality parameters associated with a communication session at one or more network components of a communication network. At least one of the network components is selected to perform packet replication, if a value of the voice quality parameters deviates from a predetermined range. In accordance with a particular embodiment, replicated packets are transmitted from the selected network component along an alternate communication path. In accordance with another embodiment, an improvement in performance associated with transmission of the replicated communication packets along the alternate communication path is assessed. Transmission of the replicated communication packets may be discontinued if the improvement is below a predetermined minimum.
    • 一种用于在通信会话期间自适应地改善语音质量的方法包括监视与通信网络的一个或多个网络组件处的通信会话相关联的语音质量参数。 如果语音质量参数的值偏离预定范围,则选择至少一个网络组件来执行分组复制。 根据特定实施例,复制分组沿着备选通信路径从所选网络组件发送。 根据另一个实施例,评估与沿着替代通信路径的复制通信分组的传输相关联的性能的改进。 如果改进低于预定的最小值,则可以中断复制的通信分组的传输。
