Dual-Mode Communication Module Dynamic Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cell phones lack a dynamic communication mode switching strategy that considers user requirements when switching between GAN and G/U modes, leading to inefficient network utilization and power consumption.
Innovation Solution
An intelligent method for dynamically switching between GAN and G/U modes based on critical conditions such as remaining power, bandwidth, and credit, which determines the optimal mode for the dual-mode communication module to access, and includes a sleep mode to prevent unnecessary power consumption when no networks are available.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cell phone continuously searches for available communication networks in both GAN and G/U modes, then network availability is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic mode switching between GAN and G/U communication modes based on real-time detection of network availability and user activity state. The system transitions from static default mode selection to dynamic adaptation, adjusting communication mode according to whether the user is in idle or active state, thereby optimizing both network availability and power consumption
Solution Approach 2:
The system continuously monitors network availability in the current communication mode and uses this feedback to trigger mode switching. When network is unavailable in current mode, the system detects this condition and switches to the alternative mode, creating a closed-loop feedback mechanism that maintains network availability while avoiding continuous searching in both modes simultaneously
2Adaptability or versatility
If the cell phone switches between GAN and G/U modes based on default user preferences, then network access flexibility is improved, but switching reliability deteriorates due to lack of concrete switching strategies
Solution Approach 1:
The patent performs preliminary registration with the GAN controller when entering GAN mode, before actual communication is needed. This preliminary action ensures that when switching from G/U mode to GAN mode, the device is already registered and can immediately access the network, eliminating delays and improving switching reliability
Solution Approach 2:
The system automatically detects network availability and performs mode switching based on predefined conditions without requiring manual user intervention. The device monitors its own state (idle vs. active) and network conditions, making autonomous decisions about mode switching, thereby improving both flexibility and reliability
3Use of energy by moving object
If the cell phone enters sleep mode to save power, then power consumption is reduced, but network response time increases
Solution Approach 1:
The patent implements dynamic adjustment of sleep mode duration based on user activity state. When the user is in idle state, the system enters sleep mode for extended periods to maximize power savings. When user activity is detected, the system wakes up and switches to active communication mode, dynamically adapting sleep duration to current usage patterns
Solution Approach 2:
The system performs preliminary network availability detection and mode switching preparation before actually needing to communicate. By checking network availability and preparing the appropriate communication mode in advance, the system minimizes the time needed to become fully operational after waking from sleep mode

AI summary
With the aid of critical conditions including remaining power of a communication module and both an available bandwidth and a credit of utilizing communication functions of said communication module, and by cooperating with available network services of said communication module, a communication network currently appropriates for said communication module to be switched to is determined, for achieving an aim of retrieving network services and taking requirements of users into consideration simultaneously. Moreover, when there are no available network services for the communication module, said communication module enters a sleep state for about less than ten seconds, for preventing said communication module from consuming additional power or from bringing in unnecessary consumption in other aspects, where both the additional power and the unnecessary consumption in other aspects are caused from the fact that the communication module searches for available network services continuously.
