Wireless LAN Terminal Security Policy Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless LAN communication terminals cannot configure a desired security level with other-end terminals without increasing power consumption, as they lack the ability to set security levels between the access point and the other-end terminal, and direct connections complicate network control.
Innovation Solution
A wireless LAN communication terminal that acquires security function information and current connection information from the other-end terminal, compares it with its own security policy, and selects either a direct or relay connection to meet the required security level, thereby configuring the appropriate connection method without increasing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless LAN communication terminal directly connects to the other-end terminal to configure security, then security configuration capability is improved, but network control complexity increases and power consumption increases
Solution Approach 1:
The access point serves as an intermediary that provides security information about the other-end terminal to the wireless LAN communication terminal. This allows the terminal to acquire necessary security configuration data without directly controlling the other-end terminal, thus avoiding increased network control complexity while maintaining security configuration capability.
2Reliability
If the wireless LAN communication terminal directly connects to the other-end terminal to configure security, then security configuration capability is improved, but power consumption increases
Solution Approach 1:
By using the access point as an intermediary to acquire security information, the wireless LAN communication terminal avoids the need to operate in access point mode for direct connections, which significantly reduces power consumption while still enabling proper security configuration through the relay connection.
3Device complexity
If the wireless LAN communication terminal uses relay connection via access point, then network control is simplified and power consumption is reduced, but security level may be insufficient
Solution Approach 1:
The wireless LAN communication terminal acquires security function information and current connection information from the other-end terminal before establishing the relay connection. This preliminary acquisition of security information allows the terminal to determine in advance whether the relay connection can meet the required security level, and switch to direct connection if necessary, thus ensuring adequate security while maintaining simplified network control.
4Ease of manufacture
If the wireless LAN communication terminal acquires security information after attachment, then connection establishment is simplified, but security configuration capability is lost
Solution Approach 1:
The wireless LAN communication terminal acquires security function information and current connection information from the other-end terminal before finalizing the connection establishment. This preliminary action ensures that the terminal has all necessary security information available when configuring the relay connection, preventing any loss of security configuration capability while maintaining simplified connection establishment procedures.

AI summary
A wireless LAN communication terminal and its communication control method are provided that make it possible to configure desired security between the terminal and an other-end terminal, without increasing power consumption of the terminals. The wireless LAN communication terminal (103) in a wireless LAN system including an access point (102), if the other-end terminal (101) has connected to the access point 102, acquires from the other-end terminal information about security functions the other-end terminal has and information about a current connection with the access point; compares the security function information and the connection information on the other-end terminal with its own security policy; selects, based on results of the comparisons, either a direct connection (106) with the other-end terminal or a relay connection (105) via the access point so that the security policy is met; and performs communication with the other-end terminal by using the selected connection.
