Shared Address Group Management for Wi-Fi Wearables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for managing groups of Wi-Fi-enabled wearable devices require each device to perform independent connection setup procedures, leading to increased connection setup signaling overhead and latency, which can result in unsatisfactory user experiences due to prolonged application start times and network resource utilization.
Innovation Solution
Implementing a method where a shared address is established for a group of wearable devices, allowing one device to perform the connection setup on behalf of the others, thereby reducing the number of connection setups and leveraging multi-link operation to differentiate and manage traffic using unique link identifiers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each wearable device performs independent connection setup procedures, then each device can establish its own unique connection, but connection setup latency and signaling overhead increase
Solution Approach 1:
Multiple wearable devices share a common MAC address for connection setup, merging their identification functions. The group of wearable devices presents a single shared address to the wireless communication device, allowing one connection setup procedure to establish links for multiple devices simultaneously, thereby reducing connection setup latency and signaling overhead while maintaining reliable connections for each device through unique link identifiers.
2Reliability
If each wearable device performs independent connection setup procedures, then individual device connectivity is ensured, but network signaling overhead increases
Solution Approach 1:
The patent merges the connection setup signaling for multiple wearable devices into a single procedure by using a shared MAC address. Instead of each device independently exchanging authentication and association frames, the group presents one shared address, reducing the number of signaling exchanges required while maintaining individual device connectivity through unique link identifiers assigned to each device.
3Loss of time
If a shared address is used for group connection setup, then connection setup latency is reduced, but device differentiation capability may be compromised
Solution Approach 1:
The patent segments the addressing function into two layers: a shared MAC address for group identification and connection setup, and unique link identifiers for individual device differentiation. This segmentation allows the system to benefit from reduced connection setup latency using the shared address while maintaining the ability to differentiate and manage individual devices through their unique link identifiers in the network layer.

AI summary
This disclosure provides methods, components, devices and systems for managing a group of Wi-Fi-enabled wearable or handheld wireless devices using a shared address. Some aspects more specifically relate to a negotiation of a shared address that corresponds to a group of Wi-Fi-enabled wearable or handheld devices and use of the shared address during a connection setup procedure for the group. In some implementations, by performing the connection setup procedure using the shared address, one wearable or handheld device may perform the connection setup procedure on behalf of the group. Wearable or handheld devices of the group also may exchange packets to indicate, with respect to the shared address, respective link identifiers (IDs) uniquely corresponding to each respective wearable or handheld device of the group, which the wearable or handheld devices of the group may use to differentiate traffic intended for different wearable or handheld devices of the group.
