Communication Terminal Paging Channel Database for Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies, such as eCall devices, face challenges in maintaining user privacy and data protection, particularly in allowing network operators to contact devices without compromising their location or activating them unnecessarily, as they are designed to remain dormant and untraceable.
Innovation Solution
A communication terminal equipped with a database of communication network-related data linked to paging channels, allowing it to determine its location, scan for information, and evaluate received data to establish communication only when necessary, ensuring compliance with data protection requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device continuously scans all paging channels to ensure it can be contacted, then the device can be reached by network operators, but the device consumes more energy and may be traced
Solution Approach 1:
The device performs preliminary actions by storing communication network related data and paging channel information in a database before actual communication is needed. This allows the device to quickly determine its location and scan only relevant paging channels when contacted, rather than continuously scanning all channels, thus reducing energy consumption while maintaining contactability
Solution Approach 2:
The device employs periodic scanning of paging channels based on received information indicating when to scan, rather than continuous scanning. This periodic action reduces energy consumption while ensuring the device can be contacted at appropriate intervals, resolving the contradiction between reliability and energy usage
2Loss of time
If the device scans paging channels frequently to maintain network awareness, then the device can establish communication quickly, but the device location may be tracked
Solution Approach 1:
The device performs preliminary determination of its location and stores communication network related data in a database before actual communication is needed. This preliminary action allows the device to quickly establish communication when required without frequent scanning that would reveal its location, thus reducing communication establishment time while preventing location tracking
Solution Approach 2:
The device uses received information as an intermediary to trigger scanning only when necessary. The information received via paging channels indicates when the device should scan and what paging channels to scan, allowing the device to maintain network awareness without frequent active scanning that would reveal its location
3Object-affected harmful factors
If the device remains dormant to protect user privacy, then user privacy is maintained, but the device cannot be contacted by network operators
Solution Approach 1:
The device uses received information as an intermediary mechanism to bridge the contradiction between dormancy and contactability. The information received via paging channels serves as a trigger that activates the device only when necessary, allowing the device to remain dormant for privacy protection while still being contactable by network operators through the intermediary paging channel information
Solution Approach 2:
The device performs preliminary determination of its location and stores communication network related data in a database before actual communication is needed. This preliminary preparation allows the device to quickly activate and establish communication when contacted, maintaining privacy through dormancy while ensuring reliability of contact
4Loss of information
If the device scans multiple paging channels to ensure comprehensive coverage, then all relevant information is received, but the device complexity increases
Solution Approach 1:
The device performs preliminary determination of its location and stores communication network related data and paging channel information in a database. This preliminary action allows the device to quickly identify and scan only the relevant paging channels for its location, ensuring complete information reception without the complexity of scanning all possible channels
