Solution Overview

Problem

The existing 5G network architecture faces issues with increased end-to-end transmission delays and service interruptions due to the limitation of unique uplink data transmission channel addresses, leading to processing load congestion and the need for re-establishment of channels when faults occur.

Innovation Solution

Allocating multiple pre-allocated uplink data transmission channel addresses to NG-RAN base stations, enabling flexible data transmission by setting constraints and dynamically managing these channels to enhance robustness and load balance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a unique uplink data transmission channel address is allocated to each NG-RAN base station, then the channel establishment is simplified, but the processing load congestion occurs at the UPF and the end-to-end transmission delay is increased

Engineering Contradiction:
Improvechannel establishment complexityVSAvoidend-to-end transmission delay
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The patent segments the uplink data transmission by allocating multiple uplink data transmission channel addresses (N >= 2) to each NG-RAN base station instead of a single address. This segmentation allows data packets to be distributed across multiple channels, reducing congestion at the UPF and decreasing end-to-end transmission delay while maintaining simplified channel establishment procedures.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If a unique uplink data transmission channel address is used, then the channel management is simplified, but the service interruption occurs when channel re-establishment is needed due to faults

Engineering Contradiction:
Improvechannel management easeVSAvoidservice continuity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements beforehand cushioning by pre-allocating multiple uplink data transmission channel addresses (N >= 2) to each NG-RAN base station before faults occur. When a fault is detected in one channel, the system can immediately switch to another pre-configured address without requiring channel re-establishment, thereby maintaining service continuity and reliability while keeping channel management simple.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Productivity

If multiple uplink data transmission channel addresses are allocated, then the load balance and robustness are improved, but the address allocation complexity increases

Engineering Contradiction:
Improvedata transmission efficiencyVSAvoidaddress allocation complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-allocating multiple uplink data transmission channel addresses (N >= 2) to each NG-RAN base station in advance through signaling from the core network. This preliminary allocation simplifies the overall system operation because the addresses are already configured and ready for use, eliminating the need for complex dynamic allocation algorithms and reducing address allocation complexity while maintaining improved load balance and robustness.

Inventive Principle:
Principle #10Preliminary action
