Wireless Network Access Control with Condition-Based Credentials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network access control technologies lack flexibility, leading to either resource waste or compromised network quality due to unauthorized access or overuse.
Innovation Solution
A control device that receives network access requests, determines access conditions based on preset parameters, and sends access passwords or disconnect commands to manage network access efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access control is enabled to prevent unauthorized access, then network security is improved, but network resource availability deteriorates because legitimate users cannot access when the owner is not using the network
Solution Approach 1:
The patent implements dynamic access control by allowing the network owner to temporarily suspend access control when not using the network, and re-enable it when returning. The system transitions between locked and unlocked states based on real-time owner presence, making the security mechanism adaptive rather than static.
Solution Approach 2:
The system uses feedback mechanisms where the owner's device sends status information (online/offline) to the access control system. Based on this feedback, the system automatically adjusts access control policies - enabling access when owner is offline, disabling when online - creating a closed-loop control system.
2Productivity
If access control is disabled to allow free access, then network resource availability is improved, but network service quality deteriorates due to unauthorized access and overuse
Solution Approach 1:
The access control system dynamically adjusts between permissive and restrictive modes based on owner presence. When owner is offline, access is permitted (improving availability); when online, access control is enforced (protecting service quality). This dynamic switching resolves the contradiction between availability and quality.
Solution Approach 2:
The system changes the access control parameter (locked/unlocked state) based on owner status. This parameter change allows the system to adapt its security level - high security when owner is present, low security when absent - thereby balancing service quality and availability.
3Reliability
If strict access control is enforced to maintain network quality, then network service quality is improved, but flexibility of access control deteriorates
Solution Approach 1:
The system provides flexible access control by allowing owners to dynamically switch between strict control mode (when online) and permissive mode (when offline). This temporal flexibility allows the same system to adapt to different usage scenarios and owner preferences.
Solution Approach 2:
The access control system serves multiple functions: it acts as a strict security gate when owner is online, and as an open access system when owner is offline. This multi-functionality allows a single system to handle both security enforcement and free access scenarios.

AI summary
Embodiments of the present invention disclose a wireless network access control method, device, and system. The method includes: receiving, by a control device, a wireless access request message sent by user device, where the wireless access request message includes an identifier of at least one wireless network; determining a control policy parameter corresponding to the identifier of the wireless network, where the control policy parameter includes the identifier, an access password, and a preset access condition parameter that are of the wireless network; and sending the control policy parameter to the user device when determining, according to the preset access condition parameter in the control policy parameter, that a current access condition parameter of the wireless network meets the preset access condition parameter, so that the user device accesses the wireless network according to the identifier and the access password that are of the wireless network and that are in the control policy parameter, and wireless network access can be controlled flexibly. This not only avoids a waste of wireless network resources, but also does not affect wireless network access quality.
