摘要

This disclosure describes techniques to identify and mitigate an effect of a power interruption that impacts the operation of Radio Frequency (RF) antennas associated with a telecommunications network. More specifically, an Adaptive Voltage Modification (AVM) controller is described that is configured to monitor and detect a change in voltage that occurs during a power transmission from a Direct Current (DC) power source to a Remote Radio Unit (RRU). A power interruption may include a power disruption or a power surge. The AVM controller may be configured to cause a potential transformer that is coupled between the DC power source and the RRU to incrementally step-up or step-down the voltage of a power transmission from the DC power source. In this way, the AVM controller may preemptively mitigate an impact of a power interruption on Quality of Service (QoS) parameters associated with signal data transmitted by the RF antennas.

說明書

In this example, the AVM controller may quantify the voltage-boost based at least in part on the current environmental metadata. For example, the AVM controller may retrieve historical instances of voltage-boost that occur in response to historical environmental metadata, such as network congestion, network (i.e. hardware or software) impediments, DC power source impediments, or meteorological events. Meteorological events may include weather events, such as electrical storms, that impede the transmission of signal data (i.e. voice and data communications) by the RF antennas.

The AVM controller may use one or more trained machine learning algorithms to correlate current environmental metadata with historical environmental metadata to quantify a voltage-boost that is required to maintain a threshold QoS for signal data (i.e. voice and data communications) transmitted by the RF antennas. The one or more trained machine learning algorithms may make use of techniques such as supervised learning, unsupervised learning, semi-supervised learning, naive Bayes, Bayesian networks, decision trees, neural networks, fuzzy logic models, and/or probabilistic classification models.
