Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Centralized mobility management in mobile communication systems leads to inefficiencies in data routing, increased risk of network paralysis due to single points of failure, and scalability issues caused by traffic overload in the core network.
Innovation Solution
Implementing a Corresponding GateWay (CGW) to manage mobility and facilitate direct data transmission between a Mobile Station (MS) and a Corresponding Node (CN), bypassing the core anchor, thereby optimizing data routes and reducing traffic through the core network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If centralized mobility management is used, then mobility control is simplified, but data transmission delay increases
Solution Approach 1:
The patent segments the centralized mobility management function into distributed mobility agents deployed at multiple network locations (e.g., access routers, edge routers). Each mobility agent independently manages mobility for terminals in its local area, eliminating the single centralized control point and enabling direct local routing of data traffic, thus reducing transmission delay while maintaining manageable complexity through distributed architecture
Solution Approach 2:
The patent introduces a new dimensional approach by deploying mobility agents across multiple spatial dimensions of the network (different locations, layers, and domains) rather than concentrating control in a single central point. This multi-dimensional distribution allows terminals to communicate through nearest mobility agents, significantly reducing the path length and transmission delay while keeping mobility management complexity manageable through localized decision-making
2Device complexity
If centralized mobility management is used, then mobility control is simplified, but network reliability decreases
Solution Approach 1:
The patent divides the centralized mobility management system into multiple independent mobility agents distributed across the network. Each agent operates autonomously to manage mobility for its local terminals, eliminating the single point of failure inherent in centralized systems. If one mobility agent fails, others continue to operate independently, thereby maintaining network reliability while preserving manageable complexity through modular design
Solution Approach 2:
The patent changes the structural parameter of mobility management from centralized to distributed architecture. By deploying mobility agents at multiple network locations with independent operational capabilities, the system transforms the reliability parameter from vulnerable (single point of failure) to robust (redundant distributed structure), while maintaining operational simplicity through standardized agent functionality
3Device complexity
If centralized mobility management is used, then mobility control is simplified, but network scalability worsens
Solution Approach 1:
The patent segments the mobility management function into multiple independent agents that can be independently deployed, scaled, and managed across different network locations. This segmentation allows the network to scale horizontally by adding more mobility agents as needed, rather than overloading a single centralized system, thereby improving scalability while maintaining manageable complexity through modular, standardized agent units
Solution Approach 2:
The patent introduces dynamic scalability by enabling mobility agents to be dynamically added, removed, or relocated based on network demands and terminal distribution. The distributed architecture allows flexible adaptation to changing network conditions and growth requirements, enhancing scalability while keeping individual agent complexity manageable through consistent, reusable functionality
