Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lack of guidelines for processing management frames in the MAC abstraction sub-layer leads to unclear generation and exchange of management frames, affecting device management and QoS negotiation between communication devices across different communication standards.
Innovation Solution
A method and apparatus for processing management frames in a communication device that includes a device table storing device identities and MAC addresses, allowing for determination of management frame transmission to other devices, with a management frame processor module to ensure proper frame exchange and delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If management frame processing is implemented without clear guidelines, then device management and QoS negotiation can proceed, but the process becomes unclear and unreliable
Solution Approach 1:
The patent segments the management frame processing into distinct components: frame generation at the source device, frame transmission through the network, and frame processing at the destination device. Each component has clearly defined operations, making the overall process more manageable and reliable despite the complexity of supporting multiple communication standards.
Solution Approach 2:
The patent implements a universal management frame processing mechanism that works across multiple communication standards (PLC, WiFi, Ethernet, MoCA). The MAC abstraction sub-layer provides a standardized interface that enables the same management frame processing logic to function universally across different physical media, eliminating the need for standard-specific processing rules.
2Adaptability or versatility
If multiple communication standards are supported, then versatility is improved, but the complexity of managing frame exchange increases
Solution Approach 1:
The patent introduces a MAC abstraction sub-layer as an intermediary between the upper layers and the diverse MAC protocols. This intermediary provides a unified interface for management frame processing, shielding the upper layers from the complexity of different communication standards while maintaining compatibility with multiple MAC types through standardized service access points.
Solution Approach 2:
The management frame processing mechanism is designed to be universal across multiple communication standards. The same frame generation, transmission, and processing operations work across PLC, WiFi, Ethernet, and MoCA standards, reducing the need for multiple implementations and simplifying the overall system complexity.
3Manufacturing precision
If management frame format and delivery path are defined, then processing precision is improved, but the device complexity increases
Solution Approach 1:
The patent defines precise management frame processing by segmenting the operations into distinct phases: frame generation with specific format requirements, frame transmission through defined delivery paths, and frame processing at the destination. Each phase has clearly specified operations, improving processing precision without requiring the entire system to be complex.

AI summary
A method of processing management frame for a first communication device in a network system is disclosed. The method comprises maintaining a device table including at least an identity of at least a communication device of the network system, and at least a medium access control (MAC) address corresponding to the identity, and determining whether to perform management frame transmission to a second communication device of the network system according to the existence of the identity of the second communication device in the device table.
