Solution Overview

Problem

Existing IoT deployments face significant overhead and congestion due to repetitive request and response messaging, particularly in bandwidth-limited and resource-constrained networks, leading to scalability issues and increased deployment costs.

Innovation Solution

Implementing a Service Layer (SL) with a Message Scripting Service (MSS) that can script and generate IoT application requests, detect repetitive patterns, and perform operations such as batching and filtering of responses, thereby offloading these tasks from IoT applications and devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If IoT applications repeatedly issue requests to retrieve sensor readings, then data can be retrieved, but messaging overhead and network congestion increase

Engineering Contradiction:

Improvedata retrieval capabilityVSAvoidmessaging overhead

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

The service layer performs preliminary actions by detecting repetitive request patterns and automatically generating scripted requests before the application needs to re-issue them. This includes monitoring requests, identifying patterns, creating scripted request resources, and executing them autonomously, thereby reducing the quantity of repetitive messages while maintaining data retrieval productivity

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The service layer acts as an intermediary between the IoT application and the network/devices. It introduces a message scripting service that sits between the application layer and the communication layer, automatically managing repetitive request-generation and response-handling tasks, thus reducing messaging overhead without sacrificing data retrieval capability

Inventive Principle:

Principle #24Intermediary (Mediator)

2Quantity of substance

If the service layer scripts and generates requests autonomously, then messaging overhead is reduced, but system complexity increases

Engineering Contradiction:

Improvemessaging overheadVSAvoidservice layer complexity

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The service layer implements self-service mechanisms by autonomously monitoring its own requests, detecting repetitive patterns, and automatically generating scripted requests without requiring external intervention. The system self-manages the complexity of pattern recognition, script generation, and execution, reducing messaging overhead while containing complexity within the service layer itself

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The service layer employs feedback mechanisms where it monitors outgoing requests, analyzes response patterns, and uses this information to automatically adjust and generate scripted requests. This feedback loop enables the system to manage its own complexity by learning from observed patterns and optimizing message generation autonomously

Inventive Principle:

Principle #23Feedback

3Ease of operation

If repetitive request patterns are manually managed by IoT applications, then control is maintained, but resource consumption increases

Engineering Contradiction:

Improverequest controlVSAvoidresource consumption

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent extracts the repetitive task of request generation and response handling from the IoT application layer and relocates it to the service layer. This separation allows applications to maintain control over what data is needed while the service layer handles the resource-intensive repetitive messaging, reducing overall resource consumption without sacrificing operational control

Inventive Principle:

Principle #2Taking out (Extraction)

4Productivity

If the service layer performs response processing operations, then response handling efficiency is improved, but processing overhead increases

Engineering Contradiction:

Improveresponse handling efficiencyVSAvoidprocessing overhead

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The service layer merges multiple response processing operations (filtering, aggregation, batching) into a unified scripted request execution framework. By combining these operations into automated scripts that run in sequence, the system improves response handling efficiency while minimizing the time lost to overhead through consolidated processing rather than separate manual operations

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A service layer may be configured to offload requests and responses on behalf of IoT applications in order to reduce congestion and/or overhead on underlying networks, applications and devices. The service layer may be enabled with the capability to script and generate IoT application requests such that the requests can be initiated by the service layer without the IoT application having to re-issue the same request repeatedly (e.g., to periodically retrieve a sensor reading). This scripting may be initiated by request originators. The service layer may support the capability to monitor and detect repetitive request patterns and initiate the scripting itself. This scripting functionality may enable the service layer to perform operations on behalf of IoT applications. As a result, the messaging overhead on IoT applications and devices as well as underlying networks can be minimized.
