Portable Infotainment via Dynamic SIM Twinning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current in-vehicle infotainment systems either lack portability or are limited by the performance of the paired smartphone, and users face management complexities with separate service plans for standalone IVI systems.
Innovation Solution
Implementing dynamic SIM twinning and temporary service plan transfer between user equipment and vehicles, allowing seamless replication of data functions and service plans, enabling portable and personalized infotainment without managing separate SIM plans.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standalone IVI system uses its own service plan, then it achieves independence from smartphone, but it cannot support multiple users and lacks portability
Solution Approach 1:
The IVI system achieves multi-functionality by supporting both standalone operation with its own service plan and bridged operation with smartphone integration. The system can dynamically switch between these modes, allowing it to serve as an independent infotainment system when needed while also supporting multiple users through smartphone connectivity when required.
2Adaptability or versatility
If a bridged IVI system uses smartphone for connectivity, then it supports multiple users, but performance is limited by the smartphone and connection
Solution Approach 1:
The IVI system dynamically adjusts its operational mode based on user needs and context. It can switch between bridged mode (when smartphone availability and user interaction are needed) and standalone mode (when system performance and independence are prioritized). This dynamic adaptability resolves the contradiction by allowing the system to optimize for either multi-user support or performance depending on the situation.
3Reliability
If standalone IVI system has separate service plan, then it achieves independence, but user faces management complexity with multiple service plans
Solution Approach 1:
The system merges the management of multiple service plans into a unified interface. Users can manage both the standalone IVI service plan and smartphone service plans through a single control system, eliminating the need to separately track and manage multiple service plans while maintaining the independence benefits of the standalone configuration.
4Adaptability or versatility
If smartphone is paired with bridged IVI system, then it provides communication and content, but driver attention is distracted by smartphone interactions
Solution Approach 1:
The system extracts communication and content delivery functions from direct smartphone interaction and relocates them to the IVI system's own interface. Users can access communication capabilities through the vehicle's infotainment interface without needing to physically interact with their smartphone, thereby maintaining communication functionality while eliminating the distraction of handling personal devices during driving.

AI summary
An primary user equipment (UE) comprises a transceiver and a processing circuitry operatively coupled with the transceiver and configured to determine that the primary UE entered a vehicle. The processing circuitry is configured to transmit an entrance notification, to a carrier network server, notifying that the primary UE entered the vehicle. The processing circuitry is configured to receive an allocation message from the carrier network server. The allocation message indicates that twinning has been configured between the primary UE and the vehicle. The twinning configuration includes a transfer of an allocation signal of a service plan corresponding to the primary UE from the primary UE to the vehicle.
