Multi-Link Device Discovery via MLD MAC and Private SSID
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to efficiently identify and connect non-AP MLDs with private AP MLDs in multi-link operations, leading to resource waste and latency due to unavailable MAC addresses of affiliated STAs and resource recycling issues.
Innovation Solution
An apparatus transmits the MLD MAC address of a non-AP MLD to a first AP, allowing the first AP to determine if it is associated with a private SSID of a second AP MLD, and if so, creates the second AP MLD, transmitting the private SSID for connection establishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If each AP affiliated with an AP MLD has a different MAC address, then the system can identify individual access points, but it becomes difficult to efficiently discover and connect non-AP MLDs during the discovery phase when affiliated STA MAC addresses are not stored
Solution Approach 1:
The patent introduces an intermediary identifier (the first apparatus acting as a mediator) that bridges the gap between the non-AP MLD and the second AP MLD. The intermediary receives the MLD MAC address, determines association with a private SSID, creates the second AP MLD, and transmits the private SSID for connection establishment, resolving the identification problem without requiring stored STA MAC addresses
Solution Approach 2:
The patent segments the identification and connection process into distinct phases: discovery phase using MLD MAC address identification, and connection phase using private SSID. This segmentation allows the system to use different identifiers at different stages, improving both identification accuracy and connection ease
2Adaptability or versatility
If the system uses MLD MAC address for identification during discovery phase, then connection can be established without storing affiliated STA MAC addresses, but resource recycling efficiency is reduced due to unavailable MAC addresses
Solution Approach 1:
The patent performs preliminary actions by creating the second AP MLD in advance based on the MLD MAC address association with private SSID. This preliminary creation enables subsequent efficient resource recycling while maintaining connection flexibility, as the structure is prepared beforehand but resources are allocated based on actual connection needs
3Extent of automation
If the first AP creates a second AP MLD based on MLD MAC address association, then automatic connection with private AP MLDs is enabled, but the device complexity increases due to additional creation and management operations
Solution Approach 1:
The patent implements self-service by enabling the first AP to automatically determine association between the MLD MAC address and private SSID, and autonomously create the second AP MLD without external intervention. This automation reduces manual configuration complexity while maintaining high extent of automation, as the system serves itself in the identification and creation process

AI summary
Embodiments of the present disclosure relate to apparatuses, methods, devices and computer readable storage media for identification and discovery of a device. The apparatus transmits, to a first AP in a second apparatus, an MLD MAC address of a non-AP MLD. In response to a second AP MLD in the second apparatus being created based on an association between the MLD MAC address of the non-AP MLD and a private SSID of the second AP MLD, the apparatus receives the private SSID from the second AP MLD. In turn, the apparatus establishes a connection between the apparatus and the second AP MLD using at least the private SSID.
