Higher layer compression with lower layer signaling
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.
1. A method comprising:
detecting, by a device, a triggering message configured to prompt transmission of one or more triggered messages over a high-layer channel of a link; and
transmitting one or more low-layer signaling indications over a low-layer channel of the link, wherein the one or more low-layer signaling indications correspond to the one or more triggered messages.
2. The method of claim 1 , wherein the one or more low-layer signaling indications correspond to compressed versions of the one or more triggered messages.
3. The method of claim 1 , wherein transmission of the one or more low-layer signaling indications over the low-layer channel of the link prompts an remote device on the other side of the link to regenerate the one or more triggered messages.
4. The method of claim 1 , wherein the link is a wireless link.
5. The method of claim 1 , wherein the triggered message is an application layer protocol packet that is intercepted prior to physical layer processing on a transmitter-side of the link.

7. The method of claim 1 , wherein the triggered message is an application layer protocol packet that is intercepted prior to physical layer processing on a receiver-side of the link.
8. The method of claim 1 , wherein the triggered message is a transport layer packet that is intercepted prior to physical layer processing on a receiver-side of the link.
9. The method of claim 1 , wherein a communication over the high-layer channel requires a higher degree of synchronization than that required by a communication over the low-layer channel.
