Subscriber Profile Redirection via Home Component
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data integrity issues arise in wireless communication networks due to unsynchronized profile data among components, leading to inaccurate subscriber registration status and potential service disruptions.
Innovation Solution
A mechanism that redirects messages to the home component with fully updated subscriber profile data, using a data attribute to ensure consistent and accurate information across the network, thereby preventing race conditions and service impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If profile data is distributed among multiple components for redundancy, then system reliability is improved, but data consistency and accuracy deteriorate due to synchronization issues
Solution Approach 1:
The patent introduces a home component as an intermediary that centralizes subscriber profile data management. Other network components redirect messages to the home component, which acts as a mediator to ensure data consistency while maintaining system reliability through centralized control of the most accurate profile information.
Solution Approach 2:
The patent segments the network components into home components (which store complete profile data) and other components (which handle specific network functions). This segmentation allows each component to have specialized responsibilities while the home component maintains the authoritative profile data, resolving the contradiction between distributed reliability and centralized consistency.
2Productivity
If messages are handled by any available component, then service availability is improved, but service accuracy deteriorates due to race conditions and outdated profile data
Solution Approach 1:
The home component serves as an intermediary that receives redirected messages containing service requests. This ensures that profile-based services are processed with accurate, up-to-date subscriber information from the home component, preventing race conditions while maintaining service availability through the redirection mechanism.
Solution Approach 2:
The system performs preliminary action by establishing message redirection rules in advance, directing messages to the appropriate home component before processing occurs. This preliminary routing ensures that services are always handled by components with accurate profile data, preventing accuracy issues before they can occur.
3Loss of time
If profile updates are propagated to all components, then data freshness is improved, but network overhead and complexity increase
Solution Approach 1:
Instead of propagating updates to all components, the patent uses the home component as an intermediary that maintains the authoritative profile data. Other components obtain updated profile information by redirecting queries to the home component, which reduces network overhead compared to universal propagation while maintaining data freshness through on-demand retrieval.
Data Source
AI summary
Examples herein redirect a message intended for a subscriber from a non-registered component to a home component. Examples disclose receiving, by the non-registered component, a message intended for the subscriber. The non-registered component is a component at which the subscriber did not register to gain network access. The non-registered component processes a data attribute within a profile corresponding to that subscriber. The data attribute indicates a home component at which the subscriber is registered to gain network access. The non-registered component redirects the message intended for the subscriber to the home component based on the data attribute.
