DECT Base Station Emergency Call Power Backup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunications networks fail to guarantee emergency call functionality during power failures, especially in external locations without UPS systems, such as mobile radio base stations and small cell sites, which are critical for maintaining communication services.
Innovation Solution
Implementing a method that detects power failures and switches active field sites to emergency power operation, using battery backups or UPS systems to enable emergency call functionality, and signaling connected terminals to adapt to low-power modes for extended service duration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If DECT base stations are permanently connected to the power grid for voice communication, then communication quality is improved, but service availability during power outages deteriorates
Solution Approach 1:
The patent applies preliminary action by equipping DECT base stations with battery backups before power outages occur. The base station detects power failures and automatically switches to battery power, ensuring continuous operation. This pre-configured power backup system enables the base station to maintain communication services during power outages without requiring manual intervention or infrastructure changes at customer premises.
2Reliability
If extensive UPS systems are maintained at operating centers, then network connection capability during power outages is improved, but system complexity and cost increase
Solution Approach 1:
The patent extracts the power backup function from centralized operating centers and implements it at the distributed DECT base station level. Instead of relying on extensive UPS systems at operating centers, each base station is equipped with its own battery backup, enabling autonomous operation during power outages. This decentralization simplifies the overall system by eliminating the need for complex centralized UPS infrastructure while maintaining reliability.
3Productivity
If active network elements are housed in remote locations without UPS systems, then network efficiency and cost are improved, but service reliability during power outages deteriorates
Solution Approach 1:
The patent applies local quality by providing power backup specifically at the DECT base station location rather than requiring UPS systems throughout the entire network infrastructure. The base station equipped with battery backup maintains local communication services during power outages, while other network elements can remain without UPS systems. This targeted approach ensures reliability where it matters most (at customer premises) while maintaining network efficiency and cost-effectiveness.

AI summary
The present invention relates generally to the field of telecommunications and in particular to a device and a method for efficiently providing emergency call functionality in the event of a power supply failure in telecommunications networks, comprising at least one active remote site which has at least one battery backup and/or an uninterruptible power supply system for emergency power operation. The present invention includes the steps of: detecting a power supply failure, switching the active remote site to emergency power operation and an emergency call mode due to the detected power supply failure, and sending a message to connected terminal devices indicating that a power supply failure has been detected and/or that the active remote site is switching to an emergency call mode.
