Vehicle Data Service Continuity During Network Outages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data services for vehicles often diminish or become unavailable in certain areas, leading to disruptions in navigation, media, and safety services, necessitating proactive measures to optimize data access during outages.
Innovation Solution
A method and system that predict data network connection losses based on vehicle routes and sensor data, allowing for preemptive data recording and emergency signaling to third parties when no alternate path is available, enabling continued service delivery through off-network modes and vehicle-to-vehicle communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the transport enters an area with poor data network coverage, then the transport can reach its destination, but data network connection is lost
Solution Approach 1:
The system determines the transport's route and identifies areas with poor data network coverage in advance. Before the transport enters these areas, the system pre-records necessary data segments and calculates the expected network outage duration, enabling continuous service delivery despite upcoming connection losses.
Solution Approach 2:
The server acts as an intermediary between the transport and the data network. It monitors the transport's location and network connection status, manages data segment recording and playback, and coordinates with third parties for emergency signaling, thereby maintaining service continuity during network outages.
2Reliability
If the system pre-records data segments before network outage, then data service continuity is maintained, but data storage requirements increase
Solution Approach 1:
The system records only the necessary data segments required for continuous service during the expected network outage period, rather than pre-recording all possible data. This partial action approach maintains service continuity while minimizing unnecessary data storage requirements.
Solution Approach 2:
The system calculates the expected network outage duration in advance and pre-records only the specific data segments needed for that period. This targeted preliminary action optimizes the balance between maintaining service continuity and managing data storage efficiently.
3Reliability
If the system sends emergency signals when no alternate path exists, then safety is improved, but false alarms may occur
Solution Approach 1:
The system continuously monitors the transport's location and network connection status, providing feedback to verify whether the transport has actually entered an area with no alternate paths. This feedback mechanism ensures emergency signals are sent only when truly necessary, reducing false alarms while maintaining safety monitoring.
Solution Approach 2:
The system replaces subjective judgment about emergency conditions with objective, automated monitoring of transport location, network coverage data, and route analysis. This substitution of automated systems for manual assessment reduces false alarms while improving safety monitoring reliability.

AI summary
An example operation may include one or more of determining a transport will lose a data network connection at a target time based on a route plan associated with the transport, determining an estimated amount of network down time until the transport regains the data network connection once the data network connection is lost, responsive to determining the data network connection will be lost and the estimated amount of network down time, invoking an off-network transport mode prior to the target time, responsive to invoking the off-network transport mode, recording one or more data segments of a data service currently used in the transport, and initiating the one or more data segments on a computing device at the target time.
