Solution Overview

Problem

Communication terminals in private mobile radiocommunication networks, such as Tetra, Tetrapol, or P25, have limited resources, restricting them to voice communications and low-speed data transmission, and require booting times that exceed the operational requirements for emergency services.

Innovation Solution

A dual-mode communication terminal with a narrow-band and a wide-band communication module, utilizing a simplified Linux-based first operating system for rapid startup and a more resource-intensive OS like Android or iOS for high-speed data services, allowing quick voice communication and subsequent access to high-speed data services.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a full-featured operating system (Android, iOS, Windows) is used to enable high-speed data services and rich user interface, then the terminal can access broadband networks and provide video conferencing, but the boot time exceeds 45 seconds which violates emergency service requirements

Engineering Contradiction:
Improvebroadband data service capabilityVSAvoidboot time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The operating system is segmented into two distinct parts: a lightweight first OS (e.g., Linux) that boots rapidly for narrowband communication, and a full-featured second OS (e.g., Android, iOS) that provides broadband capabilities. The terminal can switch between these OS segments based on service requirements, enabling rapid deployment for emergency services while maintaining broadband access capability when needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The terminal dynamically switches between different operating system states based on operational requirements. During emergency response scenarios, the system activates the lightweight first OS for immediate narrowband communication. When broadband services are needed and time permits, the system transitions to the second OS, providing adaptive performance optimization.

Inventive Principle:
Principle #15Dynamics

2Loss of time

If a lightweight operating system is used to achieve rapid boot time, then the terminal can start in less than 10 seconds for emergency services, but the terminal cannot access high-speed broadband data services

Engineering Contradiction:
Improveboot timeVSAvoidbroadband data service capability
Core Design Contradiction:
Loss of timeVSAdaptability or versatility

Solution Approach 1:

The terminal is designed with multi-functionality by incorporating both a lightweight first OS for rapid narrowband operations and a full-featured second OS for broadband services. This universal design allows the same hardware platform to serve both emergency response requirements and high-speed data communication needs, depending on which OS is activated.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Device complexity

If a single operating system manages both narrowband and broadband communication, then the system structure is simplified, but the boot time cannot be optimized for emergency services while maintaining broadband capability

Engineering Contradiction:
Improvesystem structureVSAvoidboot time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

Rather than using a single monolithic operating system, the solution segments the OS into two specialized components: a minimal first OS dedicated to rapid narrowband booting and a comprehensive second OS for broadband operations. This segmentation allows each OS to be optimized independently, with the first OS achieving sub-10-second boot times for emergency services.

Inventive Principle:
Principle #1Segmentation

4Productivity

If broadband communication module is used for high-speed data transmission, then video conferencing and large data exchange become possible, but the terminal requires longer boot time and may compromise security on public networks

Engineering Contradiction:
Improvedata transmission speedVSAvoidboot time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The terminal dynamically selects which operating system to activate based on the communication requirements. For time-critical narrowband emergency communications, the lightweight first OS is activated for immediate operation. When high-speed broadband data transmission is required and time allows, the system transitions to the second OS, optimizing performance for video conferencing and large data exchanges.

Inventive Principle:
Principle #15Dynamics
