Telecom Network Power Conservation via Emergency Call Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In emergency situations, such as power outages, telecommunications networks face high call loads and demand, leading to rapid depletion of backup power supplies due to non-prioritized calls, causing congestion and reducing the duration of backup power availability.
Innovation Solution
Implementing a system that maintains a permissible number list within the network to selectively route only emergency and priority calls, such as 911 and GETS/WPS, allowing power conservation by dropping non-priority calls and managing network traffic to ensure bandwidth for critical communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all calls are routed through the network during emergency situations, then comprehensive communication service is provided, but backup power supplies are depleted rapidly
Solution Approach 1:
The patent segments the call traffic into different priority categories (emergency calls, priority calls, and non-priority calls). By dividing the call handling into distinct segments with different power consumption levels, the system can maintain essential communication services while conserving backup power supplies for longer durations during emergency situations.
Solution Approach 2:
The patent applies local quality by treating different types of calls with different quality levels of service. Emergency calls receive full service with guaranteed power allocation, while non-priority calls are restricted or dropped. This differential treatment allows the system to optimize power distribution based on the specific needs of each call type.
2Reliability
If backup power is allocated to all calling traffic, then complete network functionality is maintained, but power consumption increases rapidly
Solution Approach 1:
The patent extracts non-essential call traffic (non-priority calls) from the network during emergency situations. By removing these calls from the active network traffic, the system significantly reduces power consumption while maintaining reliability for essential emergency and priority communications.
Solution Approach 2:
The patent implements partial action by providing full power allocation only to essential emergency and priority calls, rather than allocating power to all calls. This partial service model maintains sufficient network functionality for critical communications while avoiding excessive power consumption that would occur if all calls were served equally.
3Adaptability or versatility
If non-priority calls are allowed during power outages, then general communication needs are met, but emergency call bandwidth is reduced
Solution Approach 1:
The patent applies preliminary anti-action by preemptively blocking non-priority calls before they can consume network bandwidth during emergency situations. This preventive measure ensures that bandwidth is reserved for emergency calls from the outset, preventing congestion and maintaining reliable emergency communication channels.
Solution Approach 2:
The patent segments network bandwidth allocation into dedicated portions for emergency calls, priority calls, and non-priority calls. During power outages, the system allocates sufficient bandwidth to emergency calls while severely limiting or eliminating bandwidth for non-priority calls, ensuring that emergency communication reliability is maintained.

AI summary
Disclosed is a method and apparatus for conserving power in a telecommunications network during emergency situations. A permissible number list of emergency and/or priority numbers is stored in the telecommunications network. In the event of an emergency or power failure, input digits of a call to the telecommunications network are compared to the permissible number list. The call is processed in the telecommunications network and routed to its destination if the input digits match an entry in the permissible number list. The call is dropped without any further processing if the input digits do not match an entry in the permissible number list. Thus, power can be conserved in emergency situations by only allowing emergency and/or priority calls.
