摘要： The present invention concerns methods for efficiently supporting Voice over Internet Protocol (VoIP) on the Forward Packet Data Channel (F PDCH) in CDMA 2000 1xEV-DV systems. Active speech in VoIP is encoded using, for example enhanced variable rate codec (EVRC), which produces 171, 80 and 16 bits per 20 ms of speech for Rate 1, Rate %2 and Rate 1/8, respectively. However, about 60% of the time a user is inactive during a speech session, so an inordinate amount of system bandwidth is comprised of rate 1/8 VoIP packets. In one embodiment of the present invention the apparatus of the present invention identifies the Rate 1/8 voice frame packets and discards them. In another embodiment of the present invention, the apparatus of the present invention identifies the Rate 1/8 voice frame packets and selects some of them for further transmission. In both embodiments the efficiency of channel utilization is increased since the amount of channel band width used to communicate relatively little information, e.g., gaps of silence, is decreased.
摘要翻译：本发明涉及在CDMA 2000 1xEV-DV系统中有效支持前向分组数据信道（F PDCH）上的因特网协议语音（VoIP）的方法。 VoIP中的活动语音使用例如增强型可变速率编解码器（EVRC）进行编码，其分别为速率1，速率％2和速率1/8的每20毫秒的语音产生171,80和16位。然而，在用户在语音会话期间不活动的时间的大约60％，因此系统带宽的过多是由速率1/8的VoIP分组组成的。在本发明的一个实施例中，本发明的装置识别速率1/8语音帧分组并丢弃它们。在本发明的另一个实施例中，本发明的装置识别速率1/8的语音帧分组，并选择其中一些用于进一步传输。在两个实施例中，信道利用的效率增加，因为用于传达相对较少的信息的信道带宽的量，例如，沉默的间隙被减少。

摘要： The use of a cellular system's packet data channel for transport of speech communications is enhanced by dynamically controlling the transmission of data packets that were received in error and notified to the transmitter by the receiver in accordance with an algorithm that takes into account a self-generated determination of the perceptual quality importance of the frame and is generated once for each frame by the speech encoder. The calculation of the frame importance is codec-dependent, and depends on a number of attributes associated with each particular frame, including the frame rate (for variable-rate codecs), signal classification, transition characteristics, background noise, previous frame erasures, etc. The selective reduction in transmission and retransmission increases the capacity of the cellular system while maintaining or even improving the quality of the received voice signal.
