WLAN Group Client Concurrent AP and Direct Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in maintaining concurrent wireless LAN communication with both an access point (AP) and an external device, particularly when channel frequencies differ, leading to potential loss of direct communication or connection to the AP.
Innovation Solution
The electronic device configures itself as a group client for direct communication with an external device acting as a group owner, establishing a second connection with the external device for communication with an external network through a first AP, using specific communication protocols and channel configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the electronic device uses the same channel for both AP communication and direct communication with external device, then concurrent communication is enabled, but communication stability deteriorates due to potential beacon frame loss
Solution Approach 1:
The patent segments the communication channels into a first channel for AP communication and a second channel for direct communication with the external device. This separation allows both communication paths to operate independently without interfering with each other, eliminating beacon frame loss issues while maintaining concurrent communication capability.
Solution Approach 2:
The patent introduces a channel switching mechanism as an intermediary that coordinates between the first channel (AP communication) and the second channel (direct communication). This intermediary manages channel transitions and ensures smooth operation when switching between different communication modes, preventing communication failures.
2Reliability
If the electronic device switches channels to avoid beacon frame loss, then communication stability improves, but concurrent communication capability deteriorates
Solution Approach 1:
By permanently segmenting the communication into separate channels (first channel for AP, second channel for direct communication), the system maintains communication stability without sacrificing concurrent communication capability. Both channels operate simultaneously without needing to switch, resolving the contradiction between stability and productivity.
3Reliability
If the electronic device maintains separate channels for AP and direct communication, then communication stability improves, but device complexity increases
Solution Approach 1:
The patent implements a multi-functional communication module that can operate in multiple modes (AP mode, direct communication mode, and concurrent mode) using a unified channel management framework. This universal approach handles different communication scenarios through a single integrated system, reducing overall device complexity despite the multi-channel operation.
Solution Approach 2:
The patent incorporates feedback mechanisms that monitor communication quality and automatically adjust channel selections. The system receives feedback about beacon frame loss and communication stability, then dynamically optimizes channel configuration accordingly, reducing manual complexity while maintaining high reliability.
