Network Access Device Registration During Power Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current broadband communication systems lack a comprehensive method to maintain network access device registration during power loss or power diminishment, leading to disrupted outbound and inbound communications, with inbound calls receiving a busy tone even if voicemail is programmed.
Innovation Solution
A system and method that includes a network access device with backup power, a gateway, and an application server, where the network access device identifies power loss, initiates backup power, and sends registration extension messages to reconfigure communication handling, ensuring continued communication services during power outages and restoration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the network access device operates without backup power during power outages, then device complexity and cost are reduced, but communication services are disrupted and registration is lost
Solution Approach 1:
The system performs preliminary actions by sending registration extension messages before power is completely lost. When backup power is available, the device sends these messages to extend the registration timeout period on the server, ensuring continuous service even during power outages. This proactive approach maintains communication services without requiring complex backup power systems.
2Reliability
If the network access device sends frequent registration messages to maintain registration during power loss, then service continuity is improved, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts registration behavior based on power availability. When backup power is present, the device sends registration extension messages to maintain registration. When backup power is depleted, the device stops sending messages and allows registration to expire naturally. This dynamic approach maintains service continuity only when energy is available, avoiding wasteful energy consumption during power loss.
3Reliability
If the system implements comprehensive power loss detection and registration extension messaging, then communication service reliability is improved, but device complexity and operational complexity increase
Solution Approach 1:
The system implements self-service through automatic power loss detection and conditional registration extension messaging. The device autonomously monitors backup power status and decides when to send registration extension messages based on power availability. This self-service approach improves reliability without requiring complex manual operation or intervention.

AI summary
A system and method for registration of a network access device including a processor configured to identify power loss at a network access device, initiate backup power at the network access device, identify when the backup power at the network access device decreases to or below a first predetermined level, and identify when backup power at the network access device is restored to or above a second predetermined level, and a transmitter configured to transmit, to a server, a registration extension message to reconfigure conditions for handling inbound communications and a registration extension cancellation message to restore original conditions for handling inbound communications.
