On-Premises Telephony Node for Outage Service Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telephony services are disrupted during outages, preventing remote and mobile workers from accessing essential communication tools, and existing solutions fail to provide seamless integration and continuity.
Innovation Solution
Implementing a telephony node at the customer premises that uses an encrypted password stored on the client device to authenticate and provide telephony services during outages, allowing the client device to act as an intermediary for accessing telephony services via the telephony node.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If telephony services are implemented over a network (UCaaS platform), then service accessibility and modernization are improved, but service reliability deteriorates during network outages
Solution Approach 1:
The patent introduces a telephony node as an intermediary device deployed at the customer premises. This node acts as a mediator between the client device and the remote datacenter, enabling local telephony service delivery during network outages. The node receives authentication credentials from the datacenter and stores them locally, allowing the system to function autonomously when the primary network connection fails.
Solution Approach 2:
The patent implements preliminary action by pre-deploying and configuring telephony nodes at customer premises before outages occur. The nodes are pre-configured with authentication mechanisms and service routing capabilities, so they are ready to immediately take over telephony services when a network outage is detected, minimizing service disruption time.
2Reliability
If a telephony node is deployed at customer premises for outage resilience, then service continuity during outages is improved, but device complexity increases
Solution Approach 1:
The patent extracts the critical authentication and service routing functions from the centralized datacenter and places them in the distributed telephony node at the customer premises. By extracting these core functions, the system achieves local autonomy during outages while keeping the overall architecture modular and manageable. The node handles only essential telephony functions locally, with the datacenter remaining available for non-critical operations.
3Ease of operation
If client device connects to telephony node during outage, then service accessibility during outage is improved, but authentication security risks increase
Solution Approach 1:
The patent uses copying by creating a local copy of authentication credentials at the telephony node. Instead of storing actual passwords or sensitive data, the node stores encrypted credential copies that can be used for authentication during outages. This copying approach enables service continuity while maintaining security, as the credentials are encrypted and the node itself can be authenticated to the datacenter before receiving any credentials.
Solution Approach 2:
The patent implements beforehand cushioning by establishing secure authentication channels and credential storage mechanisms in advance. The system prepares authentication infrastructure before outages occur, including secure communication protocols and encrypted credential storage, so that when an outage happens, authentication can proceed securely without exposing sensitive data to risks.
Data Source
AI summary
A client device determines that a telephony outage is occurring. The client device connects to an on-premises telephony node using an encrypted password at the client device. The client device accesses a set of telephony services via the on-premises telephony node.
