Beacon Frame Generation with MBSSID Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently and securely conveying beacon information, particularly in multi-link communications where high system throughput is required for applications like video teleconferencing and HD video surveillance, due to limitations in carrying access point capabilities and BSS operation information in beacon frames.
Innovation Solution
A method and apparatus that generate beacon frames based on Multiple Basic Service Set Identifier (MBSSID) support information and non-Ultra High Reliability (UHR) Station association allowance, including capability and BSS operation information, and utilizing beacon extension frames to carry critical updates and multi-link traffic indication information, ensuring efficient data transmission and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If beacon frames carry complete AP capability and BSS operation information, then information completeness is improved, but beacon frame size and transmission overhead increase
Solution Approach 1:
The beacon information is segmented into two parts: essential beacon information included in the standard beacon frame, and extended beacon information carried in separate beacon extension frames. This segmentation allows the main beacon frame to remain compact while still providing access to complete AP capability and BSS operation information through the extension frames when needed.
Solution Approach 2:
The patent introduces a new dimension for carrying beacon information by using beacon extension frames that attach additional information elements to the standard beacon frame. This dimensional extension allows complete information to be conveyed without increasing the size of the core beacon frame structure.
2Reliability
If beacon frames include all BSS operation information, then system reliability is improved, but transmission efficiency decreases
Solution Approach 1:
By segmenting beacon information into essential and extended parts, the system ensures that critical reliability information is always present in the main beacon frame, while less critical or optional information is placed in extension frames that can be transmitted separately, thus maintaining reliability without compromising transmission efficiency.
Solution Approach 2:
The patent implements partial action by including only the most essential BSS operation information in every beacon frame, while providing optional extended information in beacon extension frames. This ensures that the core reliability requirements are always met while allowing efficient transmission when full information is not immediately needed.
3Adaptability or versatility
If multiple BSSID information is carried in beacon frames, then network versatility is improved, but beacon frame complexity increases
Solution Approach 1:
Multiple BSSID information is segmented and organized in the beacon extension frames, allowing the main beacon frame structure to remain simple while supporting versatile multi-BSSID operations. The extension frames contain the additional complexity of multiple BSSID configurations without affecting the core beacon frame design.
Solution Approach 2:
The beacon extension frames act as an intermediary structure that handles the complexity of multiple BSSID information. This intermediary layer allows the main beacon frame to remain simple while still enabling sophisticated multi-BSSID functionality through the extension mechanism.
