Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The 5G wireless communication network faces challenges in managing network traffic fluctuations between distributed units and central units, requiring a flexible mechanism for load detection and adjustment to maintain normal operation.
Innovation Solution
A channel loading pre-adjusting system that monitors transmission conditions, dynamically adjusts temporal thresholds, and determines whether to issue an alarm or suspend data transmission based on latency parameters, allowing for the establishment of alternative channels when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a predetermined network traffic mechanism is used during network deployment, then the initial network operation is stable, but the system cannot adapt to actual traffic fluctuations
Solution Approach 1:
The patent implements dynamic threshold adjustment where the temporal threshold is not fixed but adapts based on monitored transmission conditions. The system periodically detects latency parameters and dynamically modifies the threshold value to match actual network traffic patterns, enabling the network to transition from static predetermined configuration to dynamic adaptive operation that maintains stability while responding to traffic fluctuations
Solution Approach 2:
The system establishes a feedback mechanism that continuously monitors transmission conditions including latency parameters and signal quality. Based on this feedback, the distributed unit determines whether to issue alarm signals and the central unit adjusts the temporal threshold accordingly, creating a closed-loop control system that balances adaptability with operational reliability
2Adaptability or versatility
If network load detection and adjustment mechanisms are added to handle traffic fluctuations, then adaptability improves, but system complexity increases
Solution Approach 1:
The patent divides the load management functionality into distinct segments: the distributed unit handles local transmission condition monitoring and alarm signal generation, while the central unit performs threshold adjustment and overall coordination. This segmentation allows each component to have specialized, relatively simple functions rather than requiring one complex system to handle all aspects of load management
Solution Approach 2:
The temporal threshold acts as an intermediary parameter that mediates between the monitored transmission conditions and the control decisions. Rather than directly complex interactions between multiple control variables, the system uses this single temporal threshold as an intermediate control element that simplifies the adjustment mechanism while maintaining flexibility in load management

AI summary
A channel loading pre-adjusting system for 5G wireless communication adapted to be used for communicating at least one user's device with a core network includes a radio unit, a distributed unit in communication with the radio unit via a specified transmission channel, and a central unit. The distributed unit periodically detects transmission conditions of the specified channel and determines whether to issue an alarm signal accordingly, and in response to the alarm signal, the central unit determines whether to suspend data transmission via the specified transmission channel. The transmission conditions include a first group of latency parameters realized in a first number of consecutive detecting operations of the distributed unit and a temporal threshold derived from a second group of latency parameters realized in a second number of consecutive detecting operations of the distributed unit, and the first group of latency parameters are dynamically updated with time.
