Mobile Terminal Activity-Based Content Caching via Beacon Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile information terminal systems face challenges in quickly acquiring relevant content for users, as they often receive useless information due to inefficient content retrieval processes, especially when users are in motion.
Innovation Solution
A mobile information terminal equipped with a reception unit, wireless communication unit, storage unit, activity judgment unit, and access destination information generation unit, which receives signals from facility transmitters, generates access destination information based on user activity, and acquires content from a content server via a network, ensuring timely and relevant content delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the mobile information terminal receives applications from a server based on electronic tag IDs and executes them to acquire content, then the system can provide personalized content, but the content acquisition time is excessively long and the terminal may acquire useless information about already-passed facilities
Solution Approach 1:
The terminal pre-acquires and caches facility information and content from the server before the user actually visits the facility. By storing this information in advance in local storage, the terminal eliminates the need for real-time content acquisition during user movement, thus reducing content acquisition time while ensuring relevance through activity-based triggering.
Solution Approach 2:
The system dynamically adjusts content acquisition strategy based on user activity state. When the user is stationary, the terminal acquires and caches content; when the user is moving, the terminal retrieves pre-cached content. This dynamic approach optimizes both response time and content relevance by adapting to the user's movement state.
2Adaptability or versatility
If the system provides content based on previously set terminal-side information and filters service information, then personalization is achieved, but the system cannot adapt to real-time user activity and provides useless information
Solution Approach 1:
The terminal continuously monitors user activity state (moving or stationary) and uses this feedback to control content acquisition and retrieval operations. When the terminal detects the user is stationary, it triggers content acquisition; when detecting movement, it switches to retrieving pre-cached content. This feedback mechanism ensures content usefulness by aligning content delivery with actual user behavior.
Solution Approach 2:
The system performs preliminary content acquisition and caching based on predicted user destinations before the user actually arrives. By pre-fetching content during stationary periods and caching it locally, the system ensures that relevant content is available when needed, improving both adaptability to user behavior and reliability of content usefulness.

AI summary
A mobile information terminal of an information providing system includes a beacon reception unit that receives a beacon transmitted from a beacon transmitter, a wireless communication unit that communicates with a content server-via a network, a storage unit that stores a database, an activity judgment unit-that generates information based on activity of a user from information based on the beacon received by the beacon reception unit and stores a first information table including information based on the beacon and information based on the activity in the database, a URL generation unit that generates a URL indicating an access destination in the content server from the first information table, and a control unit that acquires content from the access destination indicated by the URL via the wireless communication unit.
