Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional network access control methods relying on device-specific identifiers are inefficient and slow to adapt to the growing diversity of connected devices, making them inadequate for protecting modern wireless networks from threats.
Innovation Solution
Implementing a secondary access check based on device type information, in addition to device-specific checks, to enable broader and more rapid implementation of network access limitations, allowing network operators to manage access for entire groups of devices rather than individual devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If device-specific identifier checks are used for network access control, then precise individual device management is achieved, but adaptability to diverse device types and speed of response to threats deteriorates
Solution Approach 1:
The patent segments device identification into two hierarchical levels: device-specific identifiers (IMEI, MAC address) for individual device recognition, and device type identifiers (device family, category) for group-based management. This segmentation allows the system to maintain precise individual identification while enabling efficient group-level access control, resolving the contradiction between precision and adaptability.
Solution Approach 2:
The patent introduces a new dimension of device type classification alongside traditional device-specific identifier checks. By adding this categorical dimension (e.g., IoT device, smartphone, tablet categories with specific characteristics), the system can rapidly filter and manage large groups of devices without sacrificing individual device identification precision, thus improving adaptability while maintaining measurement precision.
2Reliability
If device-specific identifier checks are used for network access control, then individual device authorization is achieved, but speed of implementing network-wide access restrictions deteriorates
Solution Approach 1:
The patent merges device-specific identifier verification with device type-based group filtering into a unified access control process. The system combines individual device checks (maintaining reliability) with group-level device type filtering (enabling rapid network-wide restrictions). This merging allows operators to implement access restrictions at the device type level, affecting entire categories of devices simultaneously while preserving individual device authorization reliability.
Solution Approach 2:
The patent implements preliminary device type classification and grouping before access control decisions are made. By pre-categorizing devices into types with specific characteristics and creating device type access control lists in advance, the system enables rapid deployment of network-wide restrictions when threats are detected, without compromising the reliability of individual device authorization checks.
3Ease of operation
If manual updates of access lists are performed, then precise control over individual devices is maintained, but responsiveness to emerging threats deteriorates
Solution Approach 1:
The patent implements automated systems that perform device type identification, classification, and access control list updates without requiring manual operator intervention for each change. The system automatically detects device types, groups them accordingly, and updates access control lists based on predefined policies and threat intelligence, enabling rapid response to emerging threats while maintaining operational simplicity through automation.
Solution Approach 2:
The patent incorporates feedback mechanisms where device access attempts, threat detections, and network events automatically trigger updates to device type access control lists. The system continuously monitors network activity, learns from new threat patterns, and dynamically adjusts access restrictions at the device type level, improving threat response efficiency while keeping the system easy to operate through automated feedback loops.

AI summary
Embodiments of the present disclosure are directed to systems and methods for group-based filtering of user devices on a wireless network. Upon a request from a user device to access a requested network service, a device specific identifier associated with the user device is used to determine one or more groups associated with the user device. Based on any access restrictions for the one or more groups associated with the user device, the requested network service may be selectively authorized or provided.
