Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wireless data terminal uses traditional single-protocol networking, then the device complexity is low, but the adaptability to different network protocols (IPv4 and IPv6) is insufficient
Solution Approach 1:
The patent segments the networking function into two independent protocol stacks (IPv4 and IPv6), each with its own protocol processing unit. This allows the terminal to support multiple protocols simultaneously while keeping each protocol implementation relatively simple and modular, resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The patent creates a universal networking architecture that can handle both IPv4 and IPv6 protocols through a common protocol processing unit that supports multiple protocol types. This multi-functional design enables the terminal to adapt to different network protocols without requiring completely separate networking subsystems, thus improving protocol adaptability while controlling device complexity.
2Adaptability or versatility
If a wireless data terminal implements dual stack support with separate protocol processing units, then the protocol adaptability improves, but the device complexity increases
Solution Approach 1:
The patent merges the common networking functions (such as packet routing, address management, and network layer processing) into a shared protocol processing unit that serves both IPv4 and IPv6 stacks. This combining approach reduces redundant components and simplifies the overall structure while maintaining dual stack functionality, thus improving protocol adaptability without proportionally increasing device complexity.
Solution Approach 2:
The patent implements a nested architecture where the protocol processing units are organized in a hierarchical structure with shared resources at lower levels and protocol-specific functions at upper levels. This nesting allows efficient resource utilization and reduces the overall structural complexity while supporting multiple protocol stacks simultaneously.

AI summary
A method for a wireless data terminal to support an Internet Protocol Version 4/Internet Protocol Version 6 (IPv4/IPv6) dual stack is described, including: the wireless data terminal maps a Modem port and a Network Driver Interface Specification (NDIS) port at a user terminal; and the wireless data terminal receives an instruction for establishing a network connection, initiates a Packet Data Protocol (PDP) context activation request to a network which a user expects to connect, and establishes the network connection according to the mapped port, after the network successfully responds to the PDP context activation request. Simultaneously, a wireless data terminal supporting an IPv4/IPv6 dual stack is described.
