Abstract: A base station comprises a transmitter configured to transmit a downlink frame. The downlink frame comprising a first configuration message associated with the configuration of Enhanced-Multicast Broadcast Service (E-MBS). The first configuration message comprises a field with an indicator to indicate a next configuration message to be decoded by a subscriber station. The subscriber station, upon decoding the first configuration message, refrains from decoding subsequent configuration messages that precede the next configuration message to be decoded by the subscriber station in accordance with the indicator.

Abstract: 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 ½ and Rate ⅛, 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 ⅛ VoIP packets. In one embodiment of the present invention the apparatus of the present invention identifies the Rate ⅛ voice frame packets and discards them. In another embodiment of the present invention, the apparatus of the present invention identifies the Rate ⅛ 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.

Abstract translation: 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½和速率per分别产生每20毫秒语音的171,80和16比特。 然而，在用户在语音会话期间不活动的时间的大约60％，因此系统带宽的过量由速率⅛VoIP分组组成。 在本发明的一个实施例中，本发明的装置识别速率⅛语音帧分组并丢弃它们。 在本发明的另一实施例中，本发明的装置识别速率⅛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。
