Localized Central Entities for Core Network Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing core network architecture experiences high communication traffic and latency due to the mobility of mobile subscribers, as central entities need to constantly interact with multiple local entities to manage and provide services, leading to increased transactions and overhead.
Innovation Solution
Establishing localized central entities closer to local entities based on mobility patterns of mobile subscribers, allowing them to maintain portions of central entity data, thereby reducing the need for frequent interactions with the central entity and minimizing network-related latencies and communication costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized entity manages all mobile subscriber data, then data consistency is maintained, but communication overhead and latency increase due to frequent interactions with multiple local entities
Solution Approach 1:
The patent creates localized central entities that store copies of mobile subscriber data locally near the access network, rather than requiring all access to the central entity. This allows local entities to retrieve data quickly from the localized entity, reducing communication latency while maintaining data consistency through periodic synchronization with the central entity.
Solution Approach 2:
The patent segments the centralized entity into multiple localized central entities distributed across different geographic locations. Each localized entity serves a specific region with multiple local entities, reducing the communication distance and overhead between local entities and the central entity, thereby decreasing latency while maintaining data consistency through coordinated updates.
2Adaptability or versatility
If mobile subscribers move frequently between locations, then network flexibility is improved, but communication traffic and transactions between central and local entities increase
Solution Approach 1:
By placing localized central entities near regional clusters of local entities, the system enables mobile subscribers to be served by the nearest localized entity as they move. This reduces the distance and number of hops for communication, decreasing traffic volume while maintaining network flexibility to handle subscriber mobility.
Solution Approach 2:
The patent introduces a geographic dimension to the network architecture by distributing localized central entities across different locations. This spatial distribution allows the system to handle subscriber mobility more efficiently by serving users from the nearest localized entity, reducing overall communication traffic while maintaining adaptability to location changes.
3Reliability
If all data requests are routed to the central entity, then data accuracy is ensured, but network performance and access speed deteriorate
Solution Approach 1:
The patent enables local entities to access data from localized central entities that store accurate copies of mobile subscriber data. This local access capability significantly improves data access speed by eliminating the need to route all requests to the distant central entity, while data accuracy is maintained through periodic synchronization and update mechanisms.
Solution Approach 2:
The patent creates copies of mobile subscriber data in localized central entities that are distributed near regional clusters of local entities. These copies enable fast local data access without compromising accuracy, as the localized entities receive periodic updates from the central entity to maintain data consistency. This copying approach resolves the contradiction between data accuracy and access speed.

AI summary
Systems and methods for managing communications among a central entity and multiple local entities in a telecommunication core network are disclosed. Localized central entities may be established across the core network based on localization patterns of telecommunication devices. The localized central entities may duplicate a portion of central entity data and provide local entities more efficient access to the data.
