1Productivity
If the bandwidth requirement of distributed service is taken into consideration during uplink-downlink ratio configuration adjusting, then the communication resource utilization efficiency is improved, but the quality of service of the cell's own service may be affected
Solution Approach 1:
The patent applies preliminary action by predicting the bandwidth requirements of distributed services before adjusting the uplink-downlink ratio configuration. The network side device predicts the bandwidth requirements of services to be distributed to neighboring cells, and uses these predictions to determine the configuration scheme in advance, thereby optimizing resource utilization while ensuring the cell's own service quality is not compromised
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting the uplink-downlink ratio configuration parameter based on predicted bandwidth requirements. The network side device changes the uplink-downlink ratio configuration parameter according to the predicted service bandwidth requirements, enabling flexible adaptation to different service distribution scenarios while maintaining service quality
2Adaptability or versatility
If the uplink-downlink ratio configuration scheme is adjusted dynamically to optimize service distribution, then the adaptability to service requirements is improved, but the complexity of configuration management increases
Solution Approach 1:
The patent applies self-service by enabling the network side device to automatically predict bandwidth requirements and determine uplink-downlink ratio configuration schemes without manual intervention. The system self-adjusts based on predicted service requirements, reducing configuration management complexity while maintaining high adaptability
Solution Approach 2:
The patent applies feedback by using predicted bandwidth requirements as input to determine the uplink-downlink ratio configuration scheme. The system continuously monitors and predicts service requirements, adjusts the configuration accordingly, and uses this feedback loop to optimize both adaptability and configuration management efficiency
