Wireless Access Control via Limited Network Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless devices repeatedly attempting to access a network with invalid credentials consume system resources and degrade network performance, as they are not granted access until authentication is successful, often due to suspended accounts or corrupted data.
Innovation Solution
Granting a wireless device limited access to an IP data network after a predetermined number of denied access requests, allowing the device to authenticate and potentially remedy credential issues, thereby reducing resource consumption and enabling access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless devices repeatedly transmit access requests when denied authorization, then the device can eventually gain access if credentials are valid, but system resources including radio bandwidth and processor load are consumed
Solution Approach 1:
The system performs preliminary actions by counting the number of failed authentication attempts before actually denying access. Instead of immediately blocking after a single failure, the system tracks cumulative attempts and applies different access control policies based on the count, thereby preventing resource waste on obviously invalid credentials while maintaining access for legitimate users who may experience temporary authentication issues.
Solution Approach 2:
The system implements feedback mechanisms where authentication failures are counted and fed back into the access control decision-making process. The network node uses the failure count to dynamically adjust access policies, providing feedback that prevents endless retry loops for invalid credentials while allowing legitimate users to succeed after initial failures.
2Loss of energy
If the network denies access immediately after authentication failure, then system resources are protected from consumption, but legitimate users with temporary credential issues cannot access the network
Solution Approach 1:
The access control policy is made dynamic rather than static. The system adjusts access decisions based on the number of failed attempts, transitioning from immediate denial to conditional access based on the failure count. This dynamic approach allows the system to adapt its behavior based on the specific circumstances of each authentication failure.
Solution Approach 2:
The system changes the parameter of access policy based on the failure count parameter. Different access policies are applied depending on how many times authentication has failed, allowing the system to differentiate between temporary issues (lower failure counts) and persistent problems (higher failure counts).
3Ease of operation
If wireless devices are granted unlimited access after authentication, then user experience is improved, but devices with invalid credentials can consume network resources indefinitely
Solution Approach 1:
The system performs preliminary validation of credentials before granting access. By counting failed authentication attempts and using this information to make access decisions, the system ensures that only devices with valid credentials eventually gain access, preventing resource consumption by devices with permanently invalid credentials.
Data Source
AI summary
A system and method for processing an access request by a wireless device to access an IP data network is provided. An access request from a wireless device is received and denied a predetermined number of times, and the wireless device is granted a limited access to the IP data network. When the access request from wireless device is authenticated, the wireless device is granted an unlimited access to the IP data network.
