Vehicle Call Routing via Embedded Module for Weak Mobile Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile telecommunications systems in vehicles often fail to leverage the potential advantages of embedded mobile telecommunications modules over portable devices, particularly in scenarios where the embedded module can provide better service due to superior reception, multiple network access, or robust connection software, leading to suboptimal call quality and reliability.
Innovation Solution
A method and system that dynamically assesses the communication capabilities of both embedded and portable mobile telecommunications devices, offering to switch calls to the embedded module when it offers better service, based on criteria such as battery level, signal strength, geographic location, and high usage areas, and automatically handling emergency calls through a back office.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the portable mobile telecommunications device is used for making calls, then the device provides mobile telephony service to vehicle occupants, but the call reliability and quality deteriorate when the portable device has low battery charge, poor signal reception, or is located in high usage areas
Solution Approach 1:
The embedded mobile telecommunications module acts as an intermediary device that provides alternative communication capability when the portable device experiences service degradation. The system monitors portable device conditions and automatically routes calls through the embedded module when criteria indicate superior service quality, thereby maintaining call reliability without depleting portable device battery.
2Reliability
If the portable mobile telecommunications device is used for making calls, then the device provides mobile telephony service to vehicle occupants, but the call quality deteriorates when the portable device is located in areas with high mobile telecommunications usage or poor signal reception
Solution Approach 1:
The embedded module serves as a mediator that bypasses the harmful environmental factors affecting portable device signal reception. By utilizing the vehicle's fixed installation and potentially different antenna positioning, the embedded module accesses mobile networks under different physical conditions, thereby improving call quality when the portable device operates in high usage areas or locations with poor signal reception.
3Reliability
If the embedded mobile telecommunications module is used for making calls, then the call reliability and quality improve, but the system complexity increases due to coordination between embedded and portable devices
Solution Approach 1:
The system implements self-service automation where the embedded module autonomously monitors portable device conditions, evaluates service quality criteria, and automatically initiates call routing decisions without requiring user intervention. The system self-manages the complexity of coordinating between embedded and portable devices through automated monitoring, evaluation, and execution of switch-over decisions based on predefined criteria such as battery level, signal strength, and location.
4Reliability
If automatic call switching is implemented from portable to embedded module, then call reliability improves in challenging conditions, but the ease of operation decreases due to automated decision-making processes
Solution Approach 1:
The system performs self-service by automatically monitoring multiple criteria (battery charge level, signal reception quality, geographic location, network usage conditions) and autonomously making call routing decisions without requiring user involvement in the evaluation process. The automated system only presents the final routing option to the user, thereby maintaining ease of operation while achieving improved call reliability through sophisticated automated decision-making.

AI summary
A method for controlling a telecommunications system of a vehicle, the system including a mobile telecommunications module embedded in the vehicle, includes determining whether the embedded mobile telecommunications module is better able to communicate with a mobile telecommunications network than is a portable mobile telecommunications device located in the vehicle, using one or more criteria. If the embedded mobile telecommunications module is better able to communicate with a mobile telecommunications network than is the portable mobile telecommunications device based on the one or more criteria, a new call is placed with a mobile telecommunications network from the embedded mobile telecommunications module.
