Vehicle Display Internet Access Information Sharing

The patent segments Internet access information into distinct categories including connectivity state information, roaming state information, WLAN information, and user preference information. This segmentation allows each type of information to be independently managed, transmitted, and processed, improving service provision efficiency while maintaining manageable device complexity through organized information architecture.

The patent creates a universal Internet access information sharing mechanism that enables both mobile terminals and image display apparatuses to function as Internet access devices for each other. This multi-functionality allows either device to provide Internet access depending on environmental conditions, improving productivity while the standardized information structure prevents complexity escalation.

The patent implements preliminary action by having devices proactively transmit Internet access information before it becomes obsolete. The controller generates and transmits updated access information (connectivity state, roaming status, WLAN configuration) in advance of environmental changes, ensuring the receiving device has current information ready for immediate use, thereby reducing information loss while maintaining high adaptability.

The patent establishes a feedback mechanism where devices continuously monitor their Internet access environment and transmit updated information when changes are detected. This feedback loop ensures information remains current and accurate, preventing information loss while enabling the system to adapt to changing environments through real-time information exchange.
