AI Technical Summary

Technical Problem

Existing indoor distributed antenna systems cannot achieve millisecond-level real-time prediction when faced with dense user migration or rapid multipath fading, resulting in degraded service quality and limited energy savings, and lack of automatic adaptive capabilities.

Method used

A bypass sampling link parallel to the main data path is constructed. By using unified time stamping and fiber optic unidirectional delay correction, the five-dimensional physical feature vector is split into service branches and quality branches. The particle search framework is used to uniformly solve for discrete rate levels and continuous sleep frame lengths. With the help of risk-driven inertial strategy and online deviation fusion, closed-loop self-correction is achieved.

Benefits of technology

Without sacrificing link latency and throughput, the granularity of energy consumption optimization and decision consistency are significantly improved, achieving a balance between real-time energy saving and service quality in high-speed fronthaul links.

Abstract

This invention discloses an energy-saving control method, device, electronic equipment, and storage medium for an indoor distributed antenna system. The embodiments of this invention first establish a bypass sampling link parallel to the main data path. Link delay is corrected by using a unified timescale and fiber optic unidirectional delay, and a five-dimensional physical feature vector is constructed to ensure data real-time performance and integrity from the source. Secondly, the five-dimensional physical feature vector is decomposed into service branches and quality branches, and parameter transmission decisions for the bypass sampling link are determined based on these service and quality branches, achieving forward-looking perception of burst traffic and channel fading. Thirdly, a particle search framework is used to uniformly solve for discrete rate levels and continuous sleep frame lengths, supplemented by a risk-driven inertial strategy and online deviation fusion, completing closed-loop self-correction of energy-saving actions on a single control plane. This scheme significantly improves the granularity and decision consistency of energy consumption optimization without sacrificing link delay and throughput.
