Solution Overview

Problem

Current communication methods among IoT devices are slow and inefficient, often requiring human intervention, and do not utilize the standard Session Initiation Protocol (SIP) or out-of-dialog SIP notifications.

Innovation Solution

Implementing Session Initiation Protocol (SIP) notifications within IoT networks, where devices send event request URIs to a hub, which responds with corresponding event response URIs, allowing out-of-dialog SIP notifications to be sent directly between devices for efficient communication and action triggering.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If current communication methods are used among IoT devices, then devices can communicate with each other, but the communication is slow and inefficient and requires human intervention

Engineering Contradiction:

Improvecommunication efficiencyVSAvoidtime for human intervention

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent implements self-service by enabling IoT devices to autonomously send and receive SIP notifications without human intervention. Devices automatically detect events, generate appropriate SIP notifications, and communicate with other devices in the network independently, eliminating the need for manual communication management and significantly improving communication efficiency.

Inventive Principle:

Principle #25Self-service

2Speed

If standard SIP protocol and out-of-dialog SIP notifications are implemented, then communication speed and efficiency improve, but device complexity increases

Engineering Contradiction:

Improvecommunication speedVSAvoidprotocol implementation complexity

Core Design Contradiction:

SpeedVSDevice complexity

Solution Approach 1:

The patent applies universality by implementing the standard SIP protocol framework that can handle multiple communication scenarios and event types through a single unified mechanism. Out-of-dialog notifications provide a universal method for event-driven communication that works across different device types and use cases, improving communication speed while managing complexity through protocol standardization.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Extent of automation

If out-of-dialog SIP notifications are used for direct device communication, then automation increases, but protocol compliance requirements become more stringent

Engineering Contradiction:

Improveautomation levelVSAvoidprotocol compliance

Core Design Contradiction:

Extent of automationVSReliability

Solution Approach 1:

The patent implements feedback mechanisms through SIP protocol responses and acknowledgments that confirm successful notification delivery and event processing. This feedback loop ensures protocol compliance by verifying that out-of-dialog notifications are properly received and handled, maintaining reliability while enabling high levels of automation in device communication.

Inventive Principle:

Principle #23Feedback

AI summary

Examples described relate to using Session Initiation Protocol (SIP) notifications for Internet of Things (IoT). In an example, in response to an event on a first device in an Internet of Things (IoT) network, the first device may send an event request Uniform Resource Identifier (URI) to a hub device. In response to the event request URI, the first device may receive an event response URI corresponding to a second device in the IoT network from the hub device. The first device may transmit an out-of-dialog Session Initiation Protocol (SIP) notification for the event to the second device.
