Disassociation Frame Target Access Point List
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face delays and inefficiencies during handoff operations between access points, particularly due to the time-consuming process of discovering and authenticating with new access points, which can lead to prolonged connection disruptions and reduced user experience.
Innovation Solution
The implementation of a protocol that proactively monitors access point health and initiates handoff procedures by providing client devices with a list of viable target access points through neighbor reports, reducing the need for extensive scanning and enabling seamless transitions between access points, including those on different communication standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication and association protocols are used during handoff, then security and connection establishment are ensured, but connection delays increase and handoff speed decreases
Solution Approach 1:
The system performs preliminary actions by having the source access point send a disassociation frame with a target access point list to the client device before the actual handoff occurs. This pre-provisioning of target AP information eliminates the need for the client to perform extensive scanning and discovery procedures, thereby reducing handoff delay while maintaining secure connection establishment through the structured disassociation protocol.
2Adaptability or versatility
If extensive scanning is performed to discover target access points, then comprehensive AP selection is achieved, but scanning time and power consumption increase
Solution Approach 1:
The invention extracts the target access point information from the scanning and discovery process by having the source access point directly provide a curated list of target APs in the disassociation frame. This removes the need for the client device to perform extensive scanning to discover available APs, thereby reducing scanning time and power consumption while still achieving comprehensive AP selection through the source AP's knowledge of the network topology.
3Device complexity
If traditional disassociation protocols are used without target information, then protocol simplicity is maintained, but connection delays increase and user experience deteriorates
Solution Approach 1:
The invention merges the target access point list into the existing disassociation frame structure, combining two functions (disassociation notification and target AP information provision) into a single protocol message. This maintains relative protocol simplicity by using the existing disassociation mechanism while adding the beneficial feature of pre-providing target AP information, thereby reducing reconnection delays without requiring a completely new protocol.
Data Source
AI summary
Systems and methods use a protocol for disassociation/deauthentication. Some embodiments relate to a first device including a circuit configured to provide at least one frame across a connection to a second device during a disassociation operation or deauthentication operation. The frame can include data indicating at least one target access point for the second device. The frame can be provided according to an 802.11 protocol and the connection can be established by using an association or authentication operation.
