    • A wireless cellular telecommunication system with an internet protocol network is provided. The wireless cellular telecommunication system comprises one or more base transceiver stations. The base transceiver stations can selectively provide a radio resource management processing. The radio resource management processing can provide a means for performing an inter-base transceiver station handover. A base transceiver station can communicate with another base transceiver station for the radio resource management processing without assistance from a centralized controller to perform control processing for the base transceiver stations. The base transceiver stations can further selectively provide a radio resource management processing, such as allocating a radio channel, deallocating a radio channel, changing a radio channel, or activating ciphering, without the assistance from a centralized controller to perform control processing for the base transceiver stations.

    • A physically compact, multichannel wireless communication transceiver architecture employs overlap and add or polyphase signal processing functionality, for wideband signal processing, together with a sample rate. A receiver section receives a plurality of multiple frequency communication channels and outputs digital signals representative of the contents of the plurality of multiple frequency communication channels. The receiver section contains an FFT-based channelizer that processes the digital signals output by a wideband digital receiver and couples respective channel outputs to a first plurality of digital signal processor units, which process (e.g. demodulate) respective ones of the digital channel signals and supply processed ones of the digital channel signals at respective output ports for distribution to an attendant voice/data network. On the transmit side, a transmit section contains a plurality of digital signal processors, respectively associated with respective ones of a plurality of incoming (voice/data) communication signals to be transmitted over respectively different frequency channels. Their processed (modulated, encoded) outputs are supplied to an inverse FFT combiner. The FFT combiner supplies a combined multichannel signal to a wideband transmitter which transmits a multiple frequency communication channel signal. Each of the channelizer and combiner may be implemented using overlap and add or polyphase filtering.

    • A method for installing software to software-defined radio equipment. The method includes the step of transferring software to one or more software-defined radio devices from a remotely located software server. The software server can be a computer operatively connected to the software-defined radio device via a communications network. The transferring step can occur while the software-defined radio device continues to perform software-defined radio functions. The software can be stored to a portion of a data store associated with the software-defined radio device which is not being used as a storage for currently running software. The software can be loaded on a restart of the software defined device. An error indication can be provided if a fault occurs in the transferring step or the loading step. The method also can include the step of reverting from the selected software to a previous software version upon a fault occurrence.
    • 一种将软件安装到软件定义无线电设备的方法。 该方法包括将软件从远程位置的软件服务器传送到一个或多个软件定义的无线电设备的步骤。 软件服务器可以是通过通信网络可操作地连接到软件定义的无线电设备的计算机。 当软件定义的无线电设备继续执行软件定义的无线电功能时,可以发生传送步骤。 软件可以存储到与软件定义的无线电设备相关联的数据存储器的一部分,该无线电设备未被用作当前运行的软件的存储器。 该软件可以重新启动软件定义的设备。 如果在传送步骤或加载步骤中发生故障,则可以提供错误指示。 该方法还可以包括在故障发生时从所选择的软件恢复到先前的软件版本的步骤。
