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

摘要

A method, system, and medium are provided for generating a profile for public safety answering platforms (PSAP). The profile identifies media formats supported by the PSAPs at various cell sector locations maintained by a network provider. A network server selects a cell sector and generates a first test emergency services call and subsequent test emergency services calls. The test emergency services call is transmitted to a PSAP. During the session with the PSAP, the subsequent test emergency services calls are processed to determine mid-call support for additional multimedia formats or codecs. The PSAP generates responses that indicate whether the PSAP supports a multimedia format or codec identified in the test emergency services call or the subsequent test emergency services call. The PSAP transmits the responses to the network server for storage in the profile.

主权项

1. Non-transitory computer-readable media having computer-executable instructions embodied thereon that, when executed, perform a method to identify public safety answering platform (PSAP) mid-call capabilities for emergency services calls, the method comprising:
selecting a cell sector maintained by a network provider; generating a first test emergency services call identifying at least one media format or codec; transmitting the first test emergency services call to a PSAP; establishing a communication session with the PSAP; during the communication session with the PSAP, initiating one or more mid-call services signals that modify the media format or codec for the session established in response to the first test emergency services call; and receiving one or more responses from the PSAP that indicates whether the PSAP supports the media format identified in the test emergency services call and whether the PSAP supports the mid-call renegotiation to the media format or media codec in the one or more mid-call services signals.
