USB Network Adapter IP Layer Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-screen collaboration methods between devices, such as those using USB connections, fail to establish IP layer connectivity, resulting in inadequate data transmission speeds and potential network sharing issues.
Innovation Solution
The method involves virtualizing a first electronic device into a USB network adapter using the Remote Network Driver Interface Specification (RNDIS) mode, enabling IP layer connection between devices through Dynamic Host Configuration Protocol (DHCP) address allocation, and disabling data transmission to the mobile communications module to prevent network sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If USB connection is used for multi-screen collaboration, then device connection is established, but data transmission speed is insufficient due to lack of IP layer connectivity
Solution Approach 1:
The patent changes the connection mode parameter from traditional USB protocol to RNDIS (Remote Network Driver Interface Specification) mode. This parameter change enables the USB connection to operate at the IP layer, transforming it into a virtual network adapter that supports network protocols. As a result, data transmission speed is significantly improved while maintaining the physical USB connection simplicity.
2Adaptability or versatility
If USB network sharing is enabled, then network connectivity is provided to second device, but security risk increases due to potential network squatting
Solution Approach 1:
The patent segments the network connection into two independent paths: a direct IP layer connection for data transmission and a controlled network sharing path. By virtualizing the first electronic device as a USB network adapter, it creates a dedicated communication channel that provides network connectivity to the second device without enabling full network sharing, thus preventing network squatting while maintaining adaptability.
Solution Approach 2:
The virtual network adapter acts as an intermediary between the first electronic device and the second device. It mediates the connection by providing IP layer connectivity for data transmission while controlling and limiting network access, preventing the second device from accessing the first device's network resources directly.
3Speed
If IP layer connection is established through virtualization, then data transmission speed improves, but device configuration complexity increases
Solution Approach 1:
The system implements self-service through automatic IP address allocation using DHCP (Dynamic Host Configuration Protocol) when RNDIS mode is activated. The virtual network adapter automatically configures network parameters and establishes IP layer connectivity without requiring manual user configuration, thereby maintaining ease of operation despite the advanced connection methodology.

AI summary
In a method for connection between a first electronic device and a second electronic device using a Universal Serial Bus (USB) system of the first electronic device, the first electronic device enables a first connection mode. The first electronic device allocates Internet Protocol (IP) addresses to the first electronic device and the second electronic device and the first electronic device disables transmitting data received using the USB system to a mobile communications system of the first electronic device.
