M2M Message Embedding in SMS Transport Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sending status or infrastructure information between M2M devices using commercially available SMS protocols and other message-based transports can be expensive due to high per-message costs, making excessive M2M communication undesirable.
Innovation Solution
Embedding M2M messages within unused space in standard messaging structures, allowing for free or low-cost messaging by utilizing existing communication channels, such as cellular networks, by compressing and combining messages with user communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If M2M messages are sent using standard SMS protocols, then status and infrastructure information can be transmitted between devices and servers, but the communication cost becomes excessively high
Solution Approach 1:
The patent combines M2M status messages with user communications by embedding them in the same SMS transport channel. User communications and M2M status/infrastructure information are merged into a single message stream, allowing both types of information to be transmitted together over the same expensive channel, thereby amortizing the cost across multiple information types.
Solution Approach 2:
The patent nests M2M messages within the structure of user communications. Status and infrastructure information are embedded inside the payload of user SMS messages, creating a nested message structure where M2M data is contained within the outer user communication envelope, maximizing the utilization of each expensive message transmission.
2Reliability
If each SMS message is treated as a separate costly transmission, then message integrity is maintained, but the overall communication expense increases significantly
Solution Approach 1:
Multiple M2M status messages are combined and embedded within a single user communication SMS. By merging multiple information payloads into one transport message, the patent reduces the number of separate expensive transmissions required while maintaining the integrity of each embedded message through proper delimiting and sequencing.
Solution Approach 2:
The patent performs preliminary embedding of M2M messages within user communications before transmission. By pre-packaging multiple status updates and infrastructure information into the user message structure in advance, the system prepares the combined payload to be sent as a single unit, reducing subsequent transmission costs while preserving message boundaries for reliable reconstruction at the receiver.

AI summary
Systems and methods for utilizing unused space in expensive message based communication to embed messages from a sender device to a receiver device to maximize payload usage over a potentially fee-based messaging service. One or more machine-to-machine messages may be embedded in unutilized transport space when other communications, that may potentially be delivered over a fee-based network, are initiated at a device. The machine-to-machine message and other communications may be extracted from a combined message package at a receiving device and processed as if they were independently transported. Machine-to-machine messages may be segmented and embedded across multiple unrelated communication packages and later reassembled.
