    • A method and apparatus for transmitting voice and data in a code division multiple access (CDMA) wireless telecommunications system is described. In an exemplary embodiment of the invention, a base station transmits voice information at a voice transmit power and data at a data transmit power that is equal to a maximum transmit power minus the voice transmit power. In a preferred embodiment of the invention, each base station reports the voice transmit power to a base station controller in 20 ms intervals. The base station controller responds by calculating an available data transmit capacity, and by forwarding data to each base station equal to the available data transmit capacity. Each base station then transmits all voice data at the current voice transmit power, and data at the current data transmission power. If the amount of data received exceeds the capacity provided by the current data transmission power, some data is not transmitted. The base station then notifies the base station controller if data was not transmitted, and the base station controller attempts to retransmit the data at a later time.
    • 描述了在码分多址(CDMA)无线电信系统中发送语音和数据的方法和装置。 在本发明的示例性实施例中,基站以语音发送功率和等于最大发送功率减去语音发送功率的数据发送功率的数据发送语音信息。 在本发明的优选实施例中,每个基站以20ms的间隔向基站控制器报告语音发送功率。 基站控制器通过计算可用数据传输容量,并将数据转发到等于可用数据传输容量的每个基站来进行响应。 每个基站然后以当前语音发送功率发送所有语音数据,并以当前数据发送功率发送数据。 如果接收到的数据量超过当前数据发送功率提供的容量,则不会发送一些数据。 然后,基站通知基站控制器是否没有发送数据,并且基站控制器尝试在稍后的时间重传数据。

    • An apparatus and method for providing communication of information between a truck tractor and trailer via existing truck wiring. At least one transmitter is located in each trailer for generating a unique identification signal representative of trailer identification information corresponding to the trailer in which the transmitter is located, modulating the identification signal, and providing the modulated identification on an existing truck power bus coupling the tractor and trailer. A receiver is located in the tractor for receiving each modulated identification signal on the power bus, demodulating each modulated identification signal and providing each demodulated identification signal to a mobile communications terminal located in the tractor for transmission to a central facility. The system may further include the transmission of trailer status or load status information by the transmitter to the receiver in a similar manner as the identification information.
    • 一种用于通过现有卡车配线提供卡车拖拉机和拖车之间的信息通信的装置和方法。 至少一个发射器位于每个拖车中,用于产生代表对应于发射机所在的预告片的拖车识别信息的唯一标识信号,调制识别信号,以及将耦合拖拉机的现有卡车电力总线上的调制标识提供 和拖车。 接收机位于拖拉机中,用于接收电力总线上的每个调制的识别信号,解调每个调制的识别信号,并将每个解调的识别信号提供给位于拖拉机中的移动通信终端,以便传输到中央设施。 该系统可以进一步包括发射机以与识别信息相似的方式向接收机发送拖车状态或负载状态信息。
