Solution Overview
Problem
Current Wi-Fi docking technologies face challenges in supporting a 1 hop protocol in 2 hop topologies and ensuring timely data transmission in docking scenarios, leading to delays and potential connection errors.
Innovation Solution
Implementing a proxy-based solution within the wireless docking center that establishes single hop communication links between a proxy source and a peripheral device, and between a proxy sink and a dockee device, allowing for direct data transmission with remapped IP and MAC addresses to optimize data flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a Wi-Fi display standard protocol is used for 1 hop direct transmission, then data transmission speed is improved, but it cannot be applied to 2 hop docking topology scenarios
Solution Approach 1:
The patent introduces a proxy device as an intermediary that bridges the dockee and peripheral device in a 2-hop topology. The proxy establishes a 1-hop direct connection with the peripheral device using Wi-Fi Display protocol, while simultaneously maintaining a connection with the dockee, thus enabling fast direct transmission where applicable while supporting the 2-hop docking architecture through the proxy mediator.
Solution Approach 2:
The patent segments the 2-hop transmission path into two separate communication channels: a 1-hop direct link between the proxy and peripheral device for high-speed data transmission, and a separate control/link management path between the dockee and proxy. This segmentation allows the Wi-Fi Display protocol to operate at optimal speed on the direct link while the overall system maintains 2-hop topology flexibility.
2Adaptability or versatility
If a 2 hop topology is used for docking scenarios, then device connectivity and versatility are improved, but data transmission latency increases
Solution Approach 1:
The proxy acts as a mediator that eliminates the need for data to traverse through the dockee in 2-hop topology. By establishing a direct 1-hop connection with the peripheral device, the proxy enables data to skip the intermediate routing step, significantly reducing transmission latency while the proxy itself maintains the docking connectivity structure.
Solution Approach 2:
The patent establishes the proxy-peripheral device 1-hop connection in advance as a preliminary action. This pre-established direct path is ready for immediate high-speed data transmission, avoiding the need to set up complex 2-hop routing paths dynamically, thus reducing latency when data transmission is required.
3Reliability
If direct 1 hop communication is established between dockee and peripheral device, then data transmission reliability is improved, but device complexity increases
Solution Approach 1:
The proxy serves as a specialized intermediary device that handles the complexity of establishing and managing direct 1-hop connections. Rather than requiring the dockee to directly manage complex peer-to-peer connections with multiple peripherals, the proxy centralizes this functionality, simplifying the overall system architecture while enabling reliable direct transmission paths.

AI summary
Methods and apparatuses are provided for supporting data transmission by a wireless docking center. A first single hop communication link is established with a peripheral device configured to receive content data. A second single hop communication link is established with a dockee device configured to transmit the content data. At least one of a message and the content data is transferred from the second communication link to the first communication link.
