Emergency Call Location File Sync for Multi-Device Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Softphone applications on computers face challenges in determining accurate location information due to reliance on local settings files, leading to registration errors and delays in emergency calls when used on multiple devices, which can be dangerous during time-sensitive situations.
Innovation Solution
Implementing a task scheduler to automatically upload and download the most recent settings file from a remote repository before initiating the emergency call location manager, ensuring the manager has access to the most up-to-date location information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the emergency call location manager relies on a local settings file stored on each computer, then the system can operate independently on each device, but registration errors occur when the same softphone number is used on multiple computers and the settings file is not synchronized
Solution Approach 1:
The system performs preliminary synchronization of the settings file from the remote repository to the local computer before the emergency call location manager needs to use it. This ensures that the local settings file is up-to-date with the latest network address to physical address mappings before emergency calling functionality is activated, preventing registration errors across multiple devices.
Solution Approach 2:
A remote settings file repository acts as an intermediary between multiple computers using the same softphone number. The repository stores the authoritative settings file with softphone number to network address mappings, allowing each local computer to synchronize its copy from this central source, ensuring consistency across all devices without requiring direct peer-to-peer communication.
2Reliability
If the settings file is automatically synchronized from a remote repository, then registration errors are prevented, but additional time is required for download and synchronization before emergency calls can be made
Solution Approach 1:
The settings file synchronization is performed in advance during system initialization or before the emergency call location manager is activated. By completing the download and synchronization of the settings file beforehand, the system ensures that when emergency calling is needed, the local settings file is already up-to-date, eliminating the need for real-time synchronization delays during actual emergency calls.
3Speed
If the emergency call location manager executes immediately when needed, then response time for emergency calls is minimized, but the settings file may be outdated or missing causing registration errors
Solution Approach 1:
The system executes the settings file synchronization task before initiating the emergency call location manager. This preliminary action ensures that the local settings file is current and complete before the location manager begins operation, allowing the location manager to execute immediately without risking registration errors due to outdated or missing settings data.
Data Source
AI summary
An emergency call location manager on a computer can use a settings file stored on the computer to determine a physical address that corresponds to a network address associated with the computer, such that the emergency call location manager can provide the physical address as dispatchable location information when a softphone application on the computer makes an emergency call. Task schedulers on computers can automatically execute tasks to download the settings file from a remote repository before the emergency call location manager begins executing on the computers, and to upload changes to the settings file made locally on the computers to the remote repository. Accordingly, the tasks can cause the emergency call location manager on a computer to use the most recent version of the settings file, even if the settings file was originally created on a different computer or a different computer made changes to the settings file.
