PSAP Media Profile Optimization via Targeted Test Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems face challenges in efficiently identifying and optimizing media format support for Public Safety Answering Platforms (PSAPs) across wireless networks, leading to unnecessary test emergency services calls and inefficient media handling capabilities determination.
Innovation Solution
A network server generates test emergency services calls to probe PSAPs for supported and unsupported media formats, updates profiles based on responses, and leverages secondary PSAPs for unsupported formats, reducing the number of test calls and optimizing media handling capabilities determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If test emergency services calls are generated for all media formats to probe PSAPs, then media handling capabilities are completely identified, but the number of test calls increases unnecessarily
Solution Approach 1:
The system performs preliminary actions by generating test emergency services calls with media formats known to be unsupported by PSAPs before actual emergency calls. This allows the network server to pre-identify unsupported formats and avoid routing calls that will be rejected, thereby reducing unnecessary test calls while maintaining accurate capability identification.
Solution Approach 2:
The system uses feedback from PSAP responses to test calls to update profiles of supported and unsupported media formats. This feedback mechanism allows the network server to learn from previous test results and optimize future test call generation, reducing the number of calls needed while maintaining comprehensive capability identification.
2Loss of information
If multiple test emergency services calls are generated to probe all media formats, then complete media support information is obtained, but system complexity and call management burden increase
Solution Approach 1:
The system segments the media format testing process by separating supported and unsupported format identification into distinct phases. Test calls are generated in organized sequences based on profile data, and responses are processed to update specific segments of PSAP capability information, making the overall complex testing process more manageable and systematic.
Solution Approach 2:
The network server acts as an intermediary that manages the complexity of generating, routing, and processing test calls. It uses profiles as intermediaries to store and retrieve PSAP capability information, simplifying the call management process while ensuring complete media support information is obtained through coordinated test call generation.
3Reliability
If PSAPs respond to all test emergency services calls, then accurate capability profiles are maintained, but PSAP workload increases
Solution Approach 1:
The system applies partial action by generating test calls only for media formats that are likely to be unsupported based on profile data, rather than testing all formats exhaustively. This reduces the number of calls PSAPs must process while maintaining accurate capability profiles, as the tests are strategically targeted rather than uniformly applied.
Solution Approach 2:
PSAPs maintain their own capability profiles by responding to test calls and updating their supported/unsupported format information. This self-service approach allows PSAPs to accurately maintain their own capability information without requiring external verification of every possible media format, reducing their processing burden while ensuring profile accuracy.

AI summary
A method, system, and medium are provided for generating a profile for public safety answering platforms. The profile identifies media formats or media format combinations that are supported by the PSAPs at various cell sector locations maintained by a network provider. A network server selects a cell sector and generates test emergency services calls. The test emergency services calls are transmitted to a PSAP but are optimized to reduce a number of test emergency services calls based on media support included in the profile of the PSAP. The PSAP generates a response that indicates whether the PSAP supports a media format identified in the test emergency services call. The PSAP may rely on capabilities of a secondary PSAP to generate the response. The PSAP transmits the response to the network server for storage in the profile.
