Identification and optimization of mid call public safety answering platform next generation 911 media support

Non-transitory computer-readable media having computer-executable instructions embodied thereon that, when executed by a public safety answering platform, perform a method to generate a response to a mid-call renegotiation of multimedia formats or multimedia codecs received from a network server, the method comprising:

• receiving a first test emergency services call, at the PSAP, identifying one or more multimedia types and multimedia codecs;
• establishing a communication session with the network server that generated the first test emergency services call;
• during the communication session with the network server, receiving one or more mid-call services signals that request modification of the media format or codec for the session established in response to the first test emergency services call;
• extracting multimedia formats or codecs requested in the test emergency services call and the one or more mid-call services signals;
• identifying current capabilities of the PSAP;
• determining whether any of the current capabilities match the extracted multimedia formats or codecs;
• generating a response that includes the matching capabilities;
• and transmitting the response to the network server.

A communication system for building a public safety answering platform (PSAP) profile, the system comprising:

• a network server configured to perform the following:
• select a cell sector maintained by a network provider, generate a first test emergency services call identifying one or more multimedia formats or codecs;
• transmit the test emergency services call to a PSAP;
• establish a session with the PSAP in response to first test emergency services call;
• initiate, during the session, one or more mid-call services signals that modify the media format or codec for the session established in response to first test emergency services;
• and receive one or more responses from the PSAP, wherein the responses indicate whether the PSAP supports the media format identified in the test emergency services call and whether the PSAP supports mid-call renegotiation to the media format or media codec in the one or more mid-call services signals.
