RAN Traffic Prediction for Base Station Energy Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional base station energy saving methods fail to ensure quality of service due to inappropriate traffic load determination, leading to overloading in target cells after radio frequency channel switching.
Innovation Solution
Implement a communication prediction-based energy saving method where a first RAN device receives prediction results from a second network device, considering future communication behaviors to determine energy saving operations, such as switching off radio frequency channels or carriers, or performing delayed scheduling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If the base station determines energy saving operation based on current traffic load only, then energy saving operation can be performed, but quality of service deteriorates due to inappropriate traffic load determination
Solution Approach 1:
The patent applies preliminary action by obtaining communication prediction results that forecast future communication behaviors before making energy saving decisions. The base station predicts future traffic loads and communication patterns, then uses these predictions to determine whether to perform energy saving operations like switching off radio frequency channels. This advance planning ensures that energy saving operations do not compromise current or future quality of service requirements.
2Use of energy by stationary object
If the base station switches off radio frequency channel based on low current load, then energy consumption is reduced, but target cell becomes overloaded causing quality of service failure
Solution Approach 1:
The patent uses communication prediction results to forecast future traffic loads in both the current and target cells before executing user migration and radio frequency channel switching operations. By predicting future communication behaviors, the base station can make informed decisions about when to switch off radio frequency channels and migrate users, ensuring that target cells will not become overloaded and that quality of service is maintained.

AI summary
A communication prediction-based energy saving method and an apparatus, the method including receiving, by a first radio access network device, from a second network device a communication prediction result that includes a communication period, traffic, a periodic communication indication, or a burst communication indication, where the traffic represents a predicted uplink or downlink data traffic volume, where the periodic communication indication represents whether communication predicted to occur is periodic, and when the communication predicted to occur is periodic, a communication interval, or the uplink or downlink data traffic volume of the periodic communication, where the burst communication indication represents whether the communication predicted to occur is bursty, and, when the communication predicted to occur is bursty, a time point, the uplink or downlink data traffic volume of the burst communication, and performing, by the first radio access network device, an energy saving operation based on the communication prediction result.
