Automated Network Access via MAC Address Broadcasting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing process for accessing a network hotspot is complex, requiring manual entry of passwords and multiple steps, which slows down the connection process and lacks security.
Innovation Solution
A method where an AP broadcasts the MAC address of a second STA device, allowing it to connect automatically by parsing a PMKID calculated from the PMKID of a first STA device, eliminating the need for manual password entry and simplifying the connection process while ensuring transmission security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the STA actively scans the AP by transmitting probe request frames, then the STA can find the AP, but the access process becomes complex and time-consuming
Solution Approach 1:
The patent applies preliminary action by having the AP pre-generate and broadcast beacon frames containing connection information (SSID, password, PMKID) before any STA needs to connect. This eliminates the need for STAs to perform active scanning and probe request transmissions, significantly reducing access time while ensuring reliable connection establishment.
2Ease of operation
If the master device transmits SSID and password to other devices, then other devices can acquire connection information, but manual password entry is still required
Solution Approach 1:
The patent implements self-service by enabling STAs to automatically obtain and use connection credentials (PMKID, password) directly from beacon frames broadcast by the AP. The STAs autonomously parse the PMKID from the beacon frame and use it for authentication without requiring manual password entry or complex user operations, simplifying the access process while maintaining ease of operation.
3Productivity
If the AP broadcasts beacon frames with connection information, then STAs can automatically connect, but transmission security may be compromised
Solution Approach 1:
The patent applies local quality by selectively including different types of connection information in beacon frames based on the specific network configuration and security requirements. The AP can broadcast PMKID for fast authentication in secure environments, or omit certain information in less secure contexts, allowing each broadcast to have the appropriate quality level for its intended use case, thus balancing access speed with transmission security.
4Ease of operation
If the STA waits for beacon frames from the AP, then the STA can passively scan, but the process is slower than active scanning
Solution Approach 1:
The patent combines preliminary action with enhanced beacon frame content by having the AP pre-configure and broadcast beacon frames that contain complete connection information including PMKID. This allows STAs to perform passive scanning efficiently by simply receiving and parsing the beacon frames, achieving both scanning simplicity and improved speed compared to traditional passive scanning, while eliminating the need for subsequent authentication handshakes.

AI summary
The present invention provides a method, apparatus and system for accessing an access point (AP). The method includes: an AP device receives a second media access control (MAC) address of a second station (STA) device transmitted by a first STA device having accessed the AP device; and the AP device broadcasts the second MAC address in a coverage range of the AP device. The second STA device is allowed to access the AP device when the second STA device succeeds in detecting the second MAC address. The technical solution solves the problem in the existing art of a complex process for a terminal to access a network hotspot, enables the second STA device to quickly connect with the AP and significantly increases the access speed of a terminal device to the AP while ensuring transmission security.
