Solution Overview

Problem

Conventional wireless communication networks waste RAN resources and degrade user experience by servicing applications with inconsistent default settings in best effort communication links, as parameters are set at fixed values independent of the specific applications or protocols, leading to sub-optimal data packet processing.

Innovation Solution

A protocol specific processor acquires application identifiers and protocol types associated with packets in the best effort communication link to determine and set quality of service parameters, optimizing radio access network resources and user experience by providing protocol-specific settings for forward and reverse link communications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If fixed default parameters are used for best effort communication links, then device complexity is reduced, but productivity decreases due to sub-optimal data packet processing

Engineering Contradiction:
Improvedata packet processing efficiencyVSAvoidparameter configuration complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements dynamic parameter selection based on protocol type detection. The system transitions from static fixed parameters to dynamic parameters that adapt to different applications (VoIP, HTTPS, FTP, etc.). The processor determines protocol types and selects corresponding optimal parameters, making the system flexible and adaptable without requiring manual configuration for each application type.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes parameters based on detected protocol types. Different parameters are applied for different applications (e.g., packet loss rate targets, retransmission settings, buffer sizes). This parameter adaptation allows the system to optimize performance for each application type while maintaining a unified processing approach, resolving the contradiction between simplicity and productivity.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If protocol-specific parameter settings are implemented, then productivity improves through optimal data packet processing, but device complexity increases due to additional processing requirements

Engineering Contradiction:
ImproveRAN resource utilizationVSAvoidprocessor functionality
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system performs self-service by automatically detecting protocol types and selecting appropriate parameters without external intervention. The processor examines packet headers, identifies application types, and autonomously configures optimal parameters. This eliminates the need for manual configuration and reduces operational complexity while maintaining high productivity through automated optimization.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent creates a universal processing mechanism that handles multiple application types through a single integrated approach. The same processor structure handles VoIP, HTTPS, FTP, and other protocols by detecting their characteristics and applying corresponding parameters. This multi-functionality improves resource utilization across diverse applications without proportionally increasing device complexity.

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

3Loss of energy

If default settings are used for all applications, then ease of operation is maintained, but loss of energy increases due to wasted RAN resources

Engineering Contradiction:
ImproveRAN resource wasteVSAvoidparameter configuration
Core Design Contradiction:
Loss of energyVSEase of operation

Solution Approach 1:

The system automatically detects application types and configures optimal parameters without user intervention. Users simply need to transmit data; the system handles protocol detection and parameter selection autonomously. This maintains ease of operation while preventing RAN resource waste by applying appropriate parameters for each application type, thereby reducing energy loss from inefficient resource allocation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent dynamically adjusts parameters based on detected protocols to optimize resource utilization. By changing parameters according to application type (e.g., enabling compression for certain protocols, adjusting packet loss thresholds), the system prevents wasting RAN resources on mismatched configurations. This automated parameter adaptation reduces energy consumption without requiring user awareness or intervention.

Inventive Principle:
Principle #35Parameter changes
