Mobile Terminal Connection Control via User Preference Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals connecting to local connection services in moving bodies, such as trains, face inefficiencies due to incorrect connections and reduced cache efficiency when user data is cached or specific content is stored, as current methods rely solely on location and network type availability, leading to unnecessary connections and reduced usability.
Innovation Solution
A method where mobile terminals send preference information to an information forwarding device before connecting, which determines if the forwarded information is appropriate for the user and sends a determination result to the terminal, preventing unnecessary connections by ensuring content appropriateness before establishing a local connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection determination is based merely on position and network type availability, then connection establishment is simple and fast, but connection accuracy deteriorates causing incorrect connections to local services
Solution Approach 1:
The system performs preliminary connection determination actions by evaluating multiple criteria (position, network type, user preferences, available services) before the mobile terminal actually connects to the local connection service. This advance evaluation ensures connection accuracy by pre-verifying appropriateness, while the complexity is managed through automated server-side processing rather than terminal-side complexity.
Solution Approach 2:
The system introduces an intermediary determination mechanism that acts as a mediator between the mobile terminal and the local connection service. This intermediary evaluates connection appropriateness based on multiple factors including user preferences and service availability, thereby improving connection accuracy without directly increasing terminal complexity, as the determination logic resides in the intermediary system.
2Productivity
If user data is cached in the mobile router, then traffic efficiency is improved, but cache efficiency deteriorates when cached content does not match user needs
Solution Approach 1:
The system performs preliminary matching between user preferences and cached content before establishing the connection. By evaluating whether the cached content in the mobile router matches the user's preferences in advance, the system ensures that traffic efficiency gains from caching are not wasted on irrelevant content, thereby maintaining both traffic efficiency and cache efficiency.
Solution Approach 2:
The system incorporates feedback mechanisms where user preferences are continuously evaluated against available cached content. This feedback loop ensures that caching decisions are aligned with actual user needs, improving cache efficiency while maintaining the traffic efficiency benefits of localized content delivery.
3Ease of operation
If the mobile terminal connects to the local connection service, then local service access is enabled, but unnecessary connections occur when content is not appropriate for the user
Solution Approach 1:
The system performs preliminary evaluation of content appropriateness based on user preferences before the mobile terminal establishes a connection to the local service. This advance check prevents unnecessary connections from occurring in the first place, thereby eliminating energy waste while preserving easy access to appropriate local services for users whose preferences match the available content.

AI summary
A technique is disclosed for preventing a mobile terminal from unnecessarily connecting to a local connection service provided by a mobile router. In a communication system, a UE 10 sends user preference information to a forwarding node 20 before the UE connects to the forwarding node, which is installed in a moving body 110 as an access point of the UE to forward information to the UE. The forwarding node determines whether information capable of being supplied to the UE is appropriate for a user of the UE based on the preference information and sends the determination result to the UE. When the UE becomes connectable to the forwarding node, the UE does not connect to the forwarding node if the information capable of being supplied is not appropriate for the user of the UE based on the determination result; else the UE connects to the forwarding node.
