Abstract: Synchronization of downlink streaming data is performed by estimating the likelihood of an underflow or an overflow in an output buffer upon receipt of each encoded data frame to determine if synchronization will be needed. After each encoded data frame is decoded it is then synchronized if the estimate indicated synchronization would be needed. Synchronization of uplink steaming data is performed by estimating the likelihood of an underflow or an overflow in an input buffer upon sending of each encoded data frame to an output modem for transmission to determine if synchronization will be needed. If needed, synchronization will be performed later on a portion of data samples taken from the input buffer that are used to form a frame of un-encoded data samples.
Abstract translation: 通过在接收到每个编码数据帧时估计输出缓冲器中的下溢或溢出的可能性来确定是否需要同步，来执行下行链路流数据的同步。 在每个编码的数据帧被解码之后，如果需要估计指示同步，则其被同步。 通过在将每个编码数据帧发送到输出调制解调器进行传输时，通过估计输入缓冲器中的下溢或溢出的可能性来确定是否需要同步，来执行上行链路蒸汽数据的同步。 如果需要，将在稍后从用于形成未编码数据样本帧的输入缓冲器取得的一部分数据样本上执行同步。

Abstract: A user equipment (UE) operating in a wireless network receives a sequence of speech frames on a speech channel. The UE demodulates at least a portion of a speech frame of the sequence of received speech frames to produce a metric value. The UE discontinues processing of the speech frame and enters a low power discontinuous reception (DRX) mode if the metric value indicates absence of valid speech data, and ignores and does not demodulate at least the next remaining bursts of the speech frame after entering DRX mode.
Abstract translation: 在无线网络中操作的用户设备（UE）在语音信道上接收语音帧序列。 UE解调接收到的语音帧序列的语音帧的至少一部分以产生度量值。 如果度量值指示不存在有效语音数据，则UE中断语音帧的处理并进入低功率不连续接收（DRX）模式，并且在进入DRX模式之后至少忽略并且不解调语音帧的下一个剩余突发 。
