Emergency Call Practice Application Redirecting Calls to Test Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in practicing emergency calls without inadvertently wasting Public Safety Answering Point (PSAP) resources, as existing methods for testing network routing of emergency calls can lead to accidental real calls and resource wastage, and current test solutions are limited in availability and duration.
Innovation Solution
A user equipment (UE) application that allows users to practice dialing emergency numbers locally or through a network practice mode, redirecting practice calls to a test server instead of a real PSAP, with features like practice mode indicators and silent dialing sequences to prevent accidental real calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users dial emergency numbers to practice, then they can test network routing and gain confidence, but PSAP resources are wasted and users may incur fines
Solution Approach 1:
The patent introduces a test server as an intermediary that receives practice emergency calls instead of routing them to real PSAPs. The test server mimics PSAP behavior for testing purposes while preventing actual resource consumption at PSAPs. This mediator allows users to practice emergency call procedures, test network routing, and gain confidence without wasting PSAP resources or incurring fines.
2Adaptability or versatility
If existing test solutions are used, then network routing can be tested, but availability is limited and duration is restricted
Solution Approach 1:
The patent creates a test server that provides universal testing capabilities for all types of emergency calls. The test server can handle practice calls from multiple users simultaneously, supports different emergency number formats, and allows unlimited testing duration. This multi-functional approach replaces limited existing test solutions with a comprehensive system that adapts to various testing scenarios without time or availability constraints.
Data Source
AI summary
An emergency call practice application can execute on user equipment (UE) to allow users to practice dialing 9-1-1 or other emergency numbers. In a network practice mode, the emergency call practice application can initiate a practice emergency call by sending a call setup message to an IP Multimedia Subsystem (IMS). The IMS can route the call setup message to a Public Safety Answering Point (PSAP) routing server, which can recognize a destination identifier in the call setup message as being associated with a test server instead of a PSAP. The PSAP routing server can forward the call setup message to the test server to connect the practice emergency call.
