Solution Overview

Problem

Existing network communication technologies face complexity and high operation costs due to the need for multiple interfaces for data forwarding between different physical mediums, such as ISDN and GGSN networks, which complicates networking environments.

Innovation Solution

A network access device establishes a binding relationship between Point-to-Point Protocol (PPP) channels on different physical mediums, enabling efficient data forwarding through a core transceiving process that converts and transmits message data between mediums using a bridging principle, simplifying the process and reducing operational costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple interfaces are configured for different physical mediums to enable data forwarding, then data forwarding capability is improved, but device complexity and operation cost increase

Engineering Contradiction:
Improvedata forwarding capabilityVSAvoidinterface complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by creating a unified interface that can handle multiple physical mediums (ISDN, GGSN, etc.) through a single standardized protocol implementation. Instead of configuring separate interfaces for each physical medium, the system uses one universal interface that adapts to different mediums, thereby reducing device complexity while maintaining data forwarding capability across various physical layers.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces an intermediary layer (the standardized interface and protocol stack) between the physical mediums and the data forwarding mechanism. This intermediary abstracts the differences between various physical mediums (ISDN, GGSN, etc.) and provides a common interface for data forwarding, eliminating the need for multiple specialized interfaces and reducing overall system complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple interfaces are configured for different physical mediums, then data forwarding between mediums is enabled, but networking environment becomes complex

Engineering Contradiction:
Improveinter-medium data forwardingVSAvoidnetworking environment complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

By implementing a universal interface that supports multiple physical mediums through a single standardized protocol, the patent simplifies the networking environment. The unified interface handles data forwarding across different mediums (ISDN, GGSN, etc.) without requiring separate interface configurations, thereby reducing networking complexity while maintaining inter-medium forwarding capability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The standardized interface acts as an intermediary that mediates between different physical mediums and the data forwarding system. It abstracts the heterogeneity of various physical layers and provides a homogeneous interface for data transmission, simplifying the networking environment by eliminating the need for complex multi-interface configurations.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple interfaces are configured for different physical mediums, then data forwarding is enabled, but operation cost increases

Engineering Contradiction:
Improvedata forwarding functionalityVSAvoidoperation cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent reduces operation cost by implementing a universal interface that can serve multiple physical mediums with a single standardized implementation. Instead of deploying and maintaining separate interface configurations for each physical medium (ISDN, GGSN, etc.), the system uses one multi-functional interface, thereby reducing deployment complexity, maintenance burden, and overall operation costs while preserving data forwarding functionality.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Productivity

If conversion and transmission process is simplified using binding relationship, then data forwarding efficiency is improved, but protocol compatibility may be affected

Engineering Contradiction:
Improvedata forwarding efficiencyVSAvoidprotocol compatibility
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent introduces a standardized interface and protocol stack as an intermediary that maintains protocol compatibility while enabling simplified data forwarding. The intermediary layer ensures that message data is properly formatted and transmitted according to standardized protocols, thereby maintaining compatibility with different physical mediums while achieving efficient data forwarding through the unified interface.

Inventive Principle:
Principle #24Intermediary (Mediator)
