    • A supervisory communications device, such as a base station within a wireless network, monitors and controls communications with a plurality of remote communications devices, such as mobile nodes, throughout a widely distributed network, including the Internet. The supervisory device establishes the upstream slot structure and allocates upstream bandwidth by sending messages over its downstream channel. The supervisory device also uses the messages and minislot counts to anticipate bursts from the remote devices. Dual registers are provided within the supervisory device to generate minislot counts. A primary register generates minislot counts for a current slot structure, and a secondary register generates minislot counts for a revised slot structure. Software executed on the supervisory device determines a switchover time for changing to the revised slot structure and revised minislot count. Prior to switchover, the revised minislot count is passed to the current slot structure processor allowing it to anticipate bursts from the remote devices using the revised slot structure. At switchover, the supervisory device also switches the revised clock along with the revised slot structure, deactivates the primary register, and switches to the secondary register to provide a seamless transition in real time.

    • A supervisory communications system (such as, a headend cable modem termination system) manages communications with a plurality of remote communications devices (such as, a cable modem). The supervisory system enables each of its physical channels to have multiple logical channels, with each logical channel having differing channel parameters or operating characteristics. As a result, different types of communication devices are permitted to coexist on the same physical spectrum. In other words, a communications device using, for example, spread spectrum modulation technologies require different operating characteristics than a communications device using, for example, time division multiplexing technologies. Although physical layer transmissions from these communications devices are not compatible, the present invention provides methodologies and/or techniques that define multiple logical channels that allow these communications devices to share the same physical spectrum of a transmission medium (such as, a HFC cable plant, wireless path, etc.) and send upstream transmissions to a single upstream receiver.
    • 监控通信系统(例如头端电缆调制解调器终端系统)管理与多个远程通信设备(例如电缆调制解调器)的通信。 监控系统使每个物理信道具有多个逻辑信道,每个逻辑信道具有不同的信道参数或操作特性。 因此,允许不同类型的通信设备在相同的物理频谱上共存。 换句话说,使用例如扩频调制技术的通信设备需要与使用例如时分复用技术的通信设备不同的操作特性。 虽然来自这些通信设备的物理层传输不兼容,但是本发明提供了定义多个逻辑信道的方法和/或技术,这些逻辑信道允许这些通信设备共享传输介质的相同物理频谱(例如,HFC电缆设备, 无线路径等),并将上行传输发送到单个上游接收机。
