Solution Overview
Problem
Current home gateways are not adaptable to USB modems from different vendors due to differences in application layer interfaces, initialization processes, and 3G system standards, leading to user inconvenience and increased expenses.
Innovation Solution
A home gateway system with a drive adaption module and application adaption module that determines the USB modem's mode, adapts the application layer interface, and selects the appropriate initialization process based on Vendor ID, Product ID, and device type parameters, enabling compatibility with any USB modem.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the home gateway uses a fixed vendor-specific USB modem configuration, then the initialization process and application layer interface are simplified, but the adaptability to different USB modem vendors and systems is reduced
Solution Approach 1:
The home gateway performs preliminary detection of USB modem information (Vendor ID, Product ID, device type parameters) upon connection, before attempting any communication or data transfer. Based on this preliminary detection, the gateway pre-selects and loads the corresponding vendor-specific drive and initialization process, avoiding the need for trial-and-error approaches and enabling seamless adaptation to different modem types.
Solution Approach 2:
The patent introduces a drive adaption module and application adaption module as intermediary components between the home gateway and USB modem. These modules act as mediators that detect modem characteristics, select appropriate vendor-specific drivers and initialization processes, and manage the communication interface adaptation, thereby isolating the gateway core from vendor-specific complexities while maintaining full compatibility.
2Ease of operation
If the home gateway supports multiple USB modem vendors and systems, then user economic burden is reduced and market popularization is facilitated, but the drive and application layer interface complexity increases
Solution Approach 1:
The patent utilizes parameter changes by detecting and responding to variations in USB modem identification parameters (Vendor ID, Product ID, device type parameters). Based on these parameter values, the system dynamically changes the drive configuration and initialization process parameters to match the specific modem type, enabling automatic adaptation without user intervention while maintaining operational simplicity.
Solution Approach 2:
The adaption functionality is segmented into distinct modules: drive adaption module for handling vendor-specific drivers, application adaption module for initialization processes, and WAN connection management module for network operations. This segmentation allows each module to independently handle specific aspects of modem compatibility, reducing overall system complexity while supporting multiple vendors through modular, vendor-specific configuration files.
3Adaptability or versatility
If the home gateway implements comprehensive USB modem detection and adaption, then compatibility with all USB modem types is achieved, but the initialization process complexity and time increase
Solution Approach 1:
The system performs preliminary detection of USB modem parameters (Vendor ID, Product ID, device type) immediately upon connection, before any communication or data transfer attempts. This preliminary action enables the gateway to pre-select the appropriate vendor-specific drive and initialization process in advance, avoiding time-consuming trial-and-error approaches and reducing overall initialization time while maintaining comprehensive compatibility.
Solution Approach 2:
The initialization process is made dynamic and adaptive rather than static and fixed. The gateway dynamically adjusts the initialization sequence, drive selection, and communication parameters based on the detected modem type and characteristics. This dynamic approach allows the system to optimize the initialization process for each specific modem type, achieving comprehensive compatibility without uniformly increasing initialization time for all modem types.

AI summary
A home gateway for adapting a Universal Serial Bus (USB) modem includes a system drive module; a wide area network (WAN) connection management module; a drive adaption module, which determines the mode of the USB modem, adapts a drive of an application layer interface of the USB modem and transmits a drive adaption complete message to an application adaption module; and the application adaption module, which selects a corresponding initialization process, initializes an application layer of the USB modem, transmits an initialization complete message to the WAN connection management module and performs a network connection via the WAN interface management module. A method for adapting the USB modem is also disclosed. The home gateway and method can reduce the economic burden of users, and facilitate the popularization of home gateway products and a wireless net surfing service via the USB modem.
