AI Technical Summary

Technical Problem

Existing wireless communication networks face challenges in managing privacy enhancement parameters efficiently, leading to high implementation costs and complexity, despite efforts like the Randomized and Modified MAC (RCM) procedure and IEEE 802.11bi task group specifications, which do not adequately address user privacy concerns.

Method used

A method and device for managing privacy levels in wireless networks by sharing and negotiating Privacy Enhancement (PE) parameters between access points (APs) and non-AP stations, allowing stations to request and agree on a set of obfuscation procedures during association, with capabilities exchange and negotiation to ensure compatibility and privacy alignment.

Benefits of technology

This approach reduces implementation costs and complexity while ensuring desired privacy levels by enabling efficient negotiation and management of PE parameters, allowing stations to align privacy settings and maintain user privacy effectively.

Abstract

The present invention relates to a method for managing privacy levels in a wireless network comprising an access point (AP) station and at least one non-AP station, the method comprising: transmitting, by a first station, which is either a non-AP station or an AP station, to a second station, a message including information indicating a set of privacy-enhancing (PE) parameters to be obfuscated, the set of PE parameters corresponding to a privacy level requested by the first station, the second station being an AP if the first station is a non-AP station, and the second station being a non-AP station if the first station is an AP; and receiving, from the second station, a response indicating whether the second station accepts the requested privacy level.
