Cell-Based Wireless Data Distribution for Disaster Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems for Social Networking Services (SNS) cannot limit information sharing to users within a specific geographical area, making it difficult for users to receive relevant disaster information during emergencies.
Innovation Solution
A wireless communication system where mobile stations assign identifiers to specific data types, such as SNS information, and wireless base stations remove these identifiers before broadcasting, ensuring that data is only distributed to users within their cell area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If information is distributed through a centralized SNS server, then information sharing functionality is achieved, but users cannot be limited to specific geographical areas and disaster information relevance is lost
Solution Approach 1:
The patent segments the centralized SNS service into distributed cell-based information distribution units. Each cell independently distributes information to users within its geographical area, eliminating the need for a centralized server to manage location-based filtering. This segmentation enables area-specific disaster information distribution while reducing system complexity.
Solution Approach 2:
The patent implements local quality by enabling each cell to independently manage and distribute information based on local geographical criteria. Users receive disaster information relevant to their specific cell area, with each cell acting autonomously to filter and distribute information locally, thereby improving information relevance without centralized control.
2Adaptability or versatility
If all users can access and share information globally, then information sharing capability is maximized, but users receive irrelevant information from areas outside their location
Solution Approach 1:
The patent applies preliminary action by pre-assigning area identifiers to information before distribution. This allows the system to automatically filter and distribute only relevant information to appropriate geographical areas without requiring complex real-time filtering, thus maintaining information sharing capability while preventing information relevance loss.
3Loss of information
If an identifier is assigned to data to indicate its type, then data categorization is achieved, but additional processing steps are required
Solution Approach 1:
The patent extracts the area identifier from the information data structure before distribution. By separating the identifier from the main data payload, the system can efficiently filter and route information based on area matching without requiring complex processing of the entire data structure, thus reducing processing complexity while maintaining accurate data type identification.
Data Source
AI summary
To limit users to share information to those located within a certain area, a wireless communication system distributes data from a wireless base station device to a mobile station. The mobile station is a mobile station that transmits data to the wireless base station device of a cell where the mobile station is located, and includes an information identifier assigning unit for assigning an identifier when the data to transmit is of a predetermined kind. The wireless base station device is a wireless base station device that broadcasts a signal to the mobile station in the cell of the wireless base station device, and includes an information distribution determining unit for when the identifier indicating that data is of the predetermined kind is assigned to data received from the mobile station, removing the identifier from the data and generating the signal including the data from which the identifier is removed.
