Abstract: Methods and devices for reducing traffic over a wireless link through the compression or suppression of high layer packets carrying predictable background data prior to transportation over a wireless link. The methods include intercepting application layer protocol packets carrying the predictable background data. In embodiments where the background data is periodic in nature, the high layer packets may be compressed into low-layer signaling indicators for communication over a low-layer control channel (e.g., an on off keying (OOK) channel). Alternatively, the high layer packets may be suppressed entirely (not transported over the wireless link) when a receiver side daemon is configured to autonomously replicate the periodic background nature according to a projected interval. In other embodiments, compression techniques may be used to reduce overhead attributable to non-periodic background data that is predictable in context.

Abstract translation: 用于通过在通过无线链路传输之前通过压缩或抑制携带可预测背景数据的高层分组来减少无线链路上的业务的方法和设备。 这些方法包括拦截携带可预测背景数据的应用层协议报文。 在背景数据本质上是周期性的实施例中，高层分组可以被压缩成低层信令指示符，用于通过低层控制信道（例如，断开键控（OOK）信道）进行通信。 或者，当接收器侧守护进程被配置为根据投影的间隔自动复制周期性背景特性时，可以完全抑制高层分组（不通过无线链路传输）。 在其他实施例中，可以使用压缩技术来减少归因于上下文中可预测的非周期性背景数据的开销。
