Wireless Base Station Dual Connection Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in reducing the time required for a communication terminal to establish connection and receive information from a wireless base station, especially when the terminal is moving at high speeds through a spot communication area.
Innovation Solution
The system introduces a wireless base station with an external communication control section, a contents memory section, an access restriction section, and a wireless communication section. It uses two types of connections: a first connection that omits authentication procedures for faster setup and a second connection that requires authentication for secure access. The system also employs a control section to manage these connections and an access restriction section to control access to contents and the server based on the connection type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication procedures are performed for connection with the wireless base station, then security and access control are improved, but the time required for connection setup increases
Solution Approach 1:
The patent applies preliminary action by pre-storing content data in the contents memory section of the wireless base station before the communication terminal arrives. This allows the terminal to quickly access pre-cached content without requiring time-consuming authentication procedures, while authentication is still performed for other operations. The system prepares data in advance so that when the terminal connects, content can be transmitted immediately.
2Speed
If the communication terminal moves at high speed through the spot communication area, then coverage area and mobility are improved, but the time available for communication setup and data transfer decreases
Solution Approach 1:
The system performs preliminary actions by caching content data in the wireless base station before the moving terminal arrives in the spot communication area. This pre-preparation eliminates the need for time-consuming data retrieval and transmission setup, allowing high-speed moving terminals to quickly connect and receive content without delay, thus accommodating high mobility scenarios.
Solution Approach 2:
The patent introduces an intermediary mechanism by using the wireless base station as a local cache server between the remote server and the moving communication terminal. The base station stores content data locally and can quickly transmit it to terminals passing through the spot area, acting as a buffer that eliminates the need for terminals to establish long-duration connections with remote servers, thus supporting high-speed mobility.
3Productivity
If authentication procedures are omitted for faster connection, then connection speed is improved, but access control and security are worsened
Solution Approach 1:
The patent applies segmentation by dividing the service into two distinct connection types: a first connection type that omits authentication for rapid content access, and a second connection type that requires authentication for secure operations. The wireless base station can selectively establish either connection type based on the terminal's needs, allowing the system to optimize for speed when appropriate while maintaining security when required.

AI summary
A wireless communication system transmits information to a communication terminal moving through a spot wireless area. In an integrated base station, an external information communication section controls communication with a server. A contents memory section stores contents received from the server. A wireless LAN communication section communicates with the communication terminal. A control section establishes connection with the communication terminal using a first connection not requiring an authentication procedure for connection with the communication terminal or using a second connection requiring the authentication procedure for connection with the communication terminal. An access control (restriction) section permits access from the communication terminal to the contents memory section and prohibits access to the server when a type of connection with the communication terminal is the first connection and permits access from the communication terminal to the contents memory section and to the server in the case of the second connection.
