Coexistence Network Integration for OWE and Open Mode Wireless
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless networks face challenges in harmoniously coexisting between opportunistic wireless encryption (OWE) and open mode, leading to inefficiencies and user confusion due to the need for dual SSIDs, which complicates network management and compatibility with legacy devices.
Innovation Solution
Implementing a coexistence network integration system that allows both OWE and legacy clients to connect under a single SSID by using intelligent management of network traffic and security protocols, where OWE clients use robust encryption and legacy clients connect in open mode, ensuring backward compatibility and segregating encrypted and unencrypted traffic to maintain network security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dual SSIDs are used to support both OWE and open mode, then compatibility with legacy devices is improved, but network management complexity increases
Solution Approach 1:
The patent segments network traffic into encrypted and unencrypted flows based on client capabilities, allowing OWE clients and legacy open mode clients to coexist under a single SSID. The access point identifies client types and directs traffic accordingly, maintaining compatibility while simplifying the user experience.
Solution Approach 2:
The access point acts as an intermediary between OWE clients and legacy clients, managing the coexistence by identifying client capabilities and routing traffic appropriately. This mediator approach allows both client types to access the network simultaneously without requiring dual SSIDs.
2Adaptability or versatility
If dual SSIDs are used to support both OWE and open mode, then device compatibility is improved, but user confusion increases
Solution Approach 1:
The patent merges the network infrastructure for OWE and open mode clients into a single SSID, eliminating the need for users to choose between different network names. This consolidation improves ease of operation while maintaining support for both client types through intelligent traffic management.
3Reliability
If OWE mode is implemented with robust encryption, then network security is improved, but compatibility with legacy devices deteriorates
Solution Approach 1:
The patent applies different security qualities to different client connections locally. OWE clients receive encrypted traffic with robust security, while legacy open mode clients receive unencrypted traffic for backward compatibility. This local differentiation allows the network to maintain high security where needed without forcing compatibility issues.

AI summary
This disclosure describes systems, methods, and devices related to coexistence network integration. A device may transmit a beacon frame or a probe response frame containing a security element that is not a robust security network element (RSNE) element to indicate opportunistic wireless encryption (OWE) support. The device may identify a first association request frame received from a first station device (STA) comprising an RSNE element with OWE Authentication Key Management (AKM) indicating a compatibility of the first STA with OWE. The device may identify a second association request frame from a second station device (STA) indicating no compatibility with OWE. The device may generate one or more encryption keys for securing data transmission with OWE-compatible STAs. The device may transmit encrypted and unencrypted versions of groupcast data frames to the first STA and the second STA.
