Vehicle Infotainment Network Access via Group Identity Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle infotainment systems face inefficiencies in network connectivity, leading to duplication of network activity and lack of association between vehicle and user mobile operator networks, which complicates service provision and management.
Innovation Solution
A method and architecture that associate an in-vehicle network access point with a user's mobile operator at a network level, enabling data exchange between the automotive carrier service platform and the mobile device, allowing SIM association and network access control based on user-defined parameters, thereby facilitating seamless network access without direct user engagement with the network service provider.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate network access is provided for vehicle and user mobile device, then network coverage and service availability are improved, but network activity duplication and service management complexity increase
Solution Approach 1:
The patent combines separate network access points (vehicle infotainment system and user mobile device) into a single coordinated network entity through group identity association. The vehicle and mobile device share a common group identity with the network, allowing unified authentication and service management while maintaining separate physical access points, thus reducing management complexity without sacrificing service availability.
Solution Approach 2:
The patent introduces a group identity as an intermediary layer between the network access points and the core network. This group identity acts as a mediator that coordinates authentication and service provisioning for multiple access points (vehicle and mobile device) without requiring separate complex configurations for each, thereby reducing service management complexity while maintaining reliable network access.
2Reliability
If embedded SIM is used in vehicle, then network connectivity is ensured, but flexibility in changing mobile operators is reduced
Solution Approach 1:
The patent implements dynamic operator selection capability where the vehicle infotainment system can automatically select from multiple available mobile operators based on current network conditions, service requirements, and user preferences. This dynamic approach allows the system to adapt to different operators without physical SIM changes, maintaining reliable connectivity while enhancing operator flexibility.
Solution Approach 2:
The patent creates a universal network access mechanism where the vehicle infotainment system can interface with multiple mobile operator networks through a common group identity framework. This multi-functional approach allows the same vehicle system to work with different operators seamlessly, providing both reliable connectivity and operator flexibility without requiring separate embedded SIMs for each operator.
3Ease of manufacture
If network association is implemented at vehicle level only, then service provision is simplified, but user-specific network optimization is lost
Solution Approach 1:
The patent segments network association into two levels: group-level association (vehicle infotainment system) and individual-level association (user mobile device). The group identity handles baseline service provisioning and authentication, while individual user identities enable personalized network optimization. This segmentation maintains service provision simplicity at the vehicle level while adding user-specific optimization capabilities.
Solution Approach 2:
The patent adds a new dimension to network association by introducing group identity as an additional layer beyond traditional individual SIM-based association. This dimensional expansion allows the system to maintain simple vehicle-level service provisioning while simultaneously enabling user-specific network optimization through the mobile device's individual identity, thus achieving both goals without conflict.
