Cell Site Backup Power Control During Outage Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cell sites experience power outages due to limited backup power storage, necessitating cost-effective solutions to maintain service continuity while optimizing backup power consumption.
Innovation Solution
Implement an observability framework (OBF) that uses artificial intelligence and machine learning to monitor and control backup power consumption at cell sites, enabling automatic notification and power-saving measures such as reducing transmission power or shutting down carriers, via a cloud-based network management system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If backup power storage capacity is increased to maintain service during power outages, then service continuity is improved, but cost increases
Solution Approach 1:
The system dynamically adjusts RRU operating parameters (transmission power, active carriers, sampling rates) based on real-time power availability and traffic conditions. During power outages, the system automatically reduces power consumption by adjusting these parameters, extending backup battery life without requiring additional battery capacity installation.
Solution Approach 2:
The invention changes operational parameters of the RRU including transmission power levels, number of active carriers, and data sampling rates based on power outage conditions. This allows the system to maintain service continuity by optimizing power consumption parameters rather than increasing physical backup power storage capacity.
2Reliability
If RRU transmits at full power to maintain user experience, then service quality is improved, but backup power depletes faster
Solution Approach 1:
The system dynamically adjusts RRU transmission power and operational parameters based on real-time conditions including power availability, traffic patterns, and user requirements. During power outages, the system automatically reduces transmission power and adjusts sampling rates to extend backup battery duration while maintaining acceptable service quality.
Solution Approach 2:
The system continuously monitors power status, traffic conditions, and service quality metrics to provide feedback for adaptive power adjustment. This closed-loop control allows the system to optimize the balance between maintaining service quality and extending backup power duration based on actual operational conditions.
3Ease of manufacture
If traditional SNMP monitoring is used to detect power outages, then implementation simplicity is improved, but response speed and automation capability are limited
Solution Approach 1:
The system implements self-service automation where the RRU automatically detects power outages through integrated sensors and autonomously executes power-saving actions without requiring external manual intervention. The system self-manages power consumption by adjusting its own operational parameters in response to power status changes.
Solution Approach 2:
The system prepares and executes power-saving configurations in advance based on predicted or detected power outages. By having pre-configured power management policies and automated response protocols ready, the system can rapidly transition to power-saving modes when outages occur, improving response speed while maintaining implementation simplicity.

AI summary
A method of controlling backup power consumption at a cellular base station subject to a power outage includes determining the cellular base station is subject to a power outage and is being supplied power from backup power storage, preparing a notification of the power outage, sending the notification to a cloud computing network so as to be recognized by an artificial intelligence cellular base station management program, receiving a backup power consumption instruction from the cloud computer network in response to the artificial intelligence cellular base station management program evaluating that at least one criterion compelling control of backup power consumption exists, and effectuating a change in backup power consumption at the cellular base station by executing the backup power consumption instruction.
