Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tethering communication systems between mobile terminal devices face challenges in balancing battery life and selecting the optimal communication standard and master-slave relationship to maximize network connectivity time, especially when one device operates as a router for another, due to varying power consumption and contractual data limitations.
Innovation Solution
A method and device configuration that acquire selection information on battery operating times for each terminal, calculate expected battery life in different tethering systems, and select the most suitable communication standard and master-slave relationship to extend network connectivity time, incorporating a control unit to manage communication modules and battery power for efficient packet routing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If tethering communication is established between battery-operated mobile terminal devices, then network connectivity is enabled for devices without direct wireless WAN access, but the battery operating time is reduced due to increased power consumption from communication modules and packet routing operations
Solution Approach 1:
The system dynamically changes operational parameters by calculating expected battery operating times for different tethering configurations (master-slave assignments, communication standards) and selecting the configuration that optimizes the balance between network connectivity and power consumption, thereby extending operational duration while maintaining adaptability
Solution Approach 2:
The system implements dynamic selection of master and slave devices based on real-time battery status information and calculated expected operating times, allowing the tethering configuration to adapt dynamically to changing battery conditions rather than using fixed assignments
2Speed
If different tethering connection systems (WiFi, Bluetooth, USB) are used between master and slave devices, then communication speed and power consumption characteristics vary, but selecting the optimal system requires complex evaluation of multiple factors including battery status, contractual data limits, and communication requirements
Solution Approach 1:
The system performs self-service by automatically acquiring battery status information from both devices, calculating expected operating times for different tethering configurations, and autonomously selecting the optimal master-slave assignment and communication standard without requiring user intervention or complex manual configuration
Solution Approach 2:
The system uses feedback from battery status information and contractual data limit information to continuously evaluate and select the optimal tethering configuration, creating a closed-loop system that adapts to changing conditions and maintains optimal performance
3Productivity
If the master device routes packets for both its own use and the slave device, then network access is provided to multiple devices, but the master device's battery consumption increases due to additional packet routing and processing operations
Solution Approach 1:
The system changes the operational parameter of master device selection based on calculated expected battery operating times, dynamically determining which device should serve as master to balance the load and extend overall system operational duration while maintaining network access capacity for multiple devices

AI summary
A mobile terminal device is connected to a network using a packet routing function of another mobile terminal device. Communication between respective mobile terminal devices can be performed in each of a plurality of tethering connection systems. When performing tethering communication, a mobile terminal device having tethering function becomes a master device and a mobile terminal device having no tethering function becomes a slave device. When both mobile terminal devices have tethering function, one mobile terminal devices becomes the master device and the other becomes the slave device. Before starting the tethering communication, state information for calculating an expected battery operating time of each mobile terminal device is acquired. A tethering connection system and a master-slave relationship are selected to maximize the expected operating time based on the remaining battery level and the expected power consumption of each mobile terminal device when starting the tethering communication.
