Uplink Channel Address Allocation for 5G Load Balancing
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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
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.
3Productivity
If multiple uplink data transmission channel addresses are allocated, then the load balance and robustness are improved, but the address allocation complexity increases
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.
