Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network selection methods fail to efficiently manage connection destination selection processing across a wide range of networks, leading to inappropriate access means selection and increased load on user terminals and network resources due to the lack of a mechanism for selecting the appropriate optimization engine based on user terminal position information.
Innovation Solution
A network selection system where each optimization engine manages a specific area and notifies user terminals of the address of the optimization engine managing their destination area, allowing for dynamic and efficient handover without increased processing load, enabling optimization across a wide range of networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single optimization engine manages all user terminals centrally, then network selection optimization can be achieved, but the physical area size that can be managed is limited and the system cannot scale to wide range networks
Solution Approach 1:
The patent divides the network management area into multiple smaller areas, each managed by a separate optimization engine. This segmentation allows the system to scale to wide network coverage while keeping each individual optimization engine's management scope manageable, resolving the contradiction between extensive network coverage and engine complexity.
2Adaptability or versatility
If user terminals store all optimization engine IP addresses and search for communicating engines, then any optimization engine can be accessed, but user terminal load and network load increase significantly
Solution Approach 1:
The optimization engines proactively notify user terminals of their IP addresses and management areas without requiring terminals to search through a list of all engines. This self-service approach reduces terminal processing load while maintaining accessibility to the appropriate optimization engine.
Solution Approach 2:
Optimization engines perform preliminary actions by pre-storing their IP addresses and management area information, and proactively notifying user terminals of this information. This eliminates the need for terminals to perform exhaustive searches, significantly reducing processing load while maintaining engine accessibility.
3Speed
If user terminals attempt to find and switch to optimization engines in a short time, then handover efficiency improves, but the time required for optimizing connection NW becomes longer without proper area-based mechanisms
Solution Approach 1:
By segmenting the network into areas with dedicated optimization engines, user terminals can quickly identify and switch to the appropriate engine based on their location, enabling fast handover while maintaining efficient connection optimization time through localized engine management.
4Reliability
If appropriate optimization engines are selected based on user terminal position information, then network selection is optimized, but no mechanism exists for selecting among multiple optimization engines with divided management areas
Solution Approach 1:
Optimization engines autonomously manage their own identification and notification to user terminals, eliminating the need for complex centralized selection mechanisms. Engines proactively provide their IP addresses and management area information, simplifying the selection process while maintaining reliable network selection based on position information.
