Regional Profile Data Caching for Wireless Network Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks face increased network traffic, latency, storage costs, and data integrity issues due to the two existing methods of managing subscriber profile data, either by deterministic routing to a permanent location or replicating data across regional centers, which lead to inefficiencies and inconsistencies.
Innovation Solution
A mechanism that collects and stores subscriber profile data from a central or last known regional repository locally within the new regional service area, allowing direct access and reducing network traffic, latency, and storage needs, while eliminating synchronization issues across regional data centers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If profile data is replicated across regional data centers, then access speed improves, but data consistency and synchronization issues worsen
Solution Approach 1:
The patent introduces a centralized profile data repository as an intermediary between mobile devices and regional service areas. Instead of replicating data across multiple regional centers (which causes synchronization issues), the system uses a single centralized repository that all regional areas access. This mediator eliminates data consistency problems while maintaining fast access through intelligent routing and caching mechanisms.
Solution Approach 2:
The patent transitions from a horizontal data distribution model (replicating profiles across multiple regional data centers) to a vertical access model (centralized repository with hierarchical access). By changing the dimensional approach from distributed storage to centralized access with regional caching, the system achieves both fast access speeds and data consistency without the synchronization problems of traditional replication.
2Reliability
If deterministic routing to permanent profile location is used, then data integrity improves, but network traffic and latency increase
Solution Approach 1:
The patent applies local quality by allowing each regional service area to have its own local profile data cache. Instead of forcing all requests to go to a single permanent location (deterministic routing), regional areas can serve profile data from their local caches when available, reducing network latency. The centralized repository ensures data integrity when local caches need updates, combining local efficiency with global consistency.
3Quantity of substance
If profile data is stored centrally, then storage costs decrease, but network traffic increases
Solution Approach 1:
The patent implements preliminary action by pre-caching profile data in regional service area repositories before it is actually needed. When a mobile device enters a regional service area, the system proactively retrieves and stores the relevant profile data locally in advance. This preliminary caching reduces subsequent network traffic for profile access, as regional areas can serve data from their local caches rather than repeatedly fetching from the centralized repository.

AI summary
Examples herein retrieve a profile data corresponding to a mobile device from a first data repository in response to the mobile device entering a regional service area. The examples store the profile data in a second data repository. The second data repository is local to the regional service area.
