Wireless Terminal Access Control for Universal and Dedicated Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems using Wi-Fi Direct lack the ability to execute different access control based on the type of connection destination wireless terminal, specifically distinguishing between universal and dedicated terminals.
Innovation Solution
A wireless terminal equipped with a terminal type determination part to identify whether another terminal is a universal or dedicated terminal based on received information, and an access control part to manage resource access accordingly, using identifiers and authentication methods to differentiate and control access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wireless terminal allows connection from any terminal type, then adaptability is improved, but security deteriorates due to inability to distinguish between universal and dedicated terminals
Solution Approach 1:
The patent applies local quality by implementing different access control policies for different terminal types. The access control part selectively applies restriction rules based on the terminal type determination, creating localized security measures tailored to each terminal category rather than applying a uniform policy across all connections.
Solution Approach 2:
The patent changes the parameter of access control restrictions based on terminal type. By determining whether a terminal is universal or dedicated, the system dynamically adjusts the level of resource access permitted, transforming a static access control system into one that adapts its security parameters according to the connecting terminal's classification.
2Reliability
If access control restrictions are applied to all terminals, then security is improved, but ease of operation deteriorates due to uniform restrictions
Solution Approach 1:
The patent implements local quality by applying access control restrictions only to universal terminals while allowing dedicated terminals to access resources without restrictions. This selective application of security measures maintains convenience for trusted dedicated terminals while enforcing security where needed, avoiding the need for uniform restrictions across all terminal types.
3Measurement precision
If terminal type identification is implemented, then access control precision is improved, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by determining terminal type during the connection establishment phase, before actual resource access occurs. The terminal type determination part identifies whether a terminal is universal or dedicated in advance, allowing the access control part to pre-configure appropriate access restrictions, thereby simplifying the overall system architecture through early classification.

AI summary
The present invention provides a communication method in a wireless communication network in which a first wireless terminal establishes a peer-to-peer wireless connection with a second wireless terminal. The first terminal determines whether or not the second wireless terminal is a universal terminal on the basis of information received from the second wireless terminal. The first wireless terminal controls access to a resource in the first wireless terminal by the second wireless terminal after a connection is established in accordance with the result of the determination.
