Access Terminal Data Distribution for Disconnected Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access terminals face challenges in providing services without a connection to a central system, particularly due to limited storage capacity and security concerns, leading to potential data loss, malfunctions, and security breaches.
Innovation Solution
A method where access terminals read and write data to communicating devices using selection criteria, enabling asynchronous data distribution between devices, allowing unconnected terminals to provide services and communicate with each other, and indirectly with the central system, ensuring robustness and security through pseudo-random data distribution and redundancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If access terminals store service information locally to operate without central system connection, then service availability in disconnected locations is improved, but data loss and service malfunction occur due to insufficient storage capacity
Solution Approach 1:
The patent segments service information into multiple types (first service information and second service information) and distributes them across different storage locations (central system and multiple access terminals). This segmentation allows the system to operate reliably in disconnected locations while maintaining data integrity through distributed redundancy.
Solution Approach 2:
The patent implements beforehand cushioning by pre-storing service information in access terminals before disconnection occurs. The system prepares and caches necessary data in advance, ensuring continuous service availability during disconnected periods while maintaining reliability through pre-positioned redundant copies of critical information.
2Adaptability or versatility
If access terminals store comprehensive service information locally, then service functionality is improved, but security risks increase due to potential data access by malicious users
Solution Approach 1:
The patent applies local quality by storing different types of service information in different locations with different access characteristics. Critical security-sensitive information remains in the central system, while less sensitive service information is cached locally in access terminals. This creates varying levels of data protection across different storage locations, balancing functionality with security.
3Adaptability or versatility
If access terminals are deployed without central system connection to expand service coverage, then number of access points is improved, but system complexity increases due to lack of centralized management
Solution Approach 1:
The patent implements self-service by enabling access terminals to autonomously store and manage service information locally without requiring continuous central system connection. Terminals can independently provide services using cached data, reducing the need for complex centralized management while expanding service coverage to locations without infrastructure.
4Ease of operation
If access terminals use limited storage capacity in communicating devices, then device portability is improved, but information completeness is reduced leading to service malfunctions
Solution Approach 1:
The patent segments information storage across multiple access terminals rather than concentrating all data in a single device. Each terminal stores a portion of service information locally, allowing the system to maintain information completeness through distributed storage while keeping individual devices portable with limited storage requirements.
Data Source
AI summary
A method of access to a local service of a device communicating via a terminal, the method comprising steps of: access to the service via an access terminal by a communicating device; reading by the access terminal of data of the communicating device, the data being personal data relating to the communicating device and/or third-party service data; writing by the access terminal of the data of the communicating device, the third-party data written being chosen from among a set of third-party service data, the choice of the third-party data to be written by the access terminal being dependent on the choosing criteria.
