Telematics Terminal VoLTE Mode Control via Network Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telematics terminals lack a method to automatically switch from 3G to VoLTE (Voice over LTE) communication mode based on network coverage changes, leading to uncertainty and potential service disruptions when VoLTE becomes available, requiring manual user intervention or separate terminal replacements.
Innovation Solution
A system and method for controlling the communication mode of telematics terminals that automatically activates or deactivates VoLTE based on network coverage changes by receiving VoLTE setting state reports, determining necessary changes, and transmitting VoLTE setting change requests to the terminal, ensuring seamless transitions between 3G and 4G networks without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual user intervention is required to switch between 3G and VoLTE modes, then user control over communication mode is improved, but operational convenience and service continuity deteriorate
Solution Approach 1:
The telematics terminal automatically detects VoLTE supportability through network information and autonomously switches communication modes between 3G and VoLTE without requiring manual user intervention, thereby maintaining service continuity while preserving user control through transparent automated operation
Solution Approach 2:
The system continuously monitors network coverage and VoLTE supportability, using this feedback information to dynamically adjust communication modes. The terminal receives network information, determines VoLTE supportability, and automatically switches modes based on real-time network conditions, ensuring optimal service continuity
2Adaptability or versatility
If separate telematics terminal replacement is required for VoLTE support, then network compatibility is improved, but device complexity and cost increase
Solution Approach 1:
The telematics terminal employs dynamic communication mode switching between 3G and VoLTE based on real-time network coverage and supportability detection. This dynamic adaptation allows a single terminal to accommodate network changes without physical replacement, reducing device complexity while maintaining network compatibility
Solution Approach 2:
The terminal is designed with multi-functionality to support both 3G and VoLTE communication modes through a unified communication module. This universal design enables the terminal to handle various network types without requiring separate dedicated terminals, thereby reducing complexity and cost
3Speed
If VoLTE function is automatically activated without network coverage check, then activation speed is improved, but service reliability deteriorates
Solution Approach 1:
The system performs preliminary detection of VoLTE supportability by acquiring network information before activating VoLTE function. This preliminary check ensures that VoLTE activation only occurs when network coverage and supportability conditions are met, thereby maintaining service reliability while enabling rapid activation when conditions are favorable

AI summary
A method for controlling a communication mode in a telematics center associated with a telematics terminal through a mobile network is disclosed. The method includes receiving a voice over LET (VoLTE) setting state report message from the telematics terminal and determining whether VoLTE setting requires a change for the telematics terminal. When the VoLTE setting requires a change, a VoLTE setting change request message is transmitted to the telematics terminal.
