Modernized messaging compatibility with interim text-to-911

A method for handling a first request for a first emergency text message session on an IP multimedia subsystem (IMS) capable network, the method comprising:

• determining a first location of a first device on the IMS capable network based on location information retrieved from a location server;
• identifying a capability of the IMS capable network to support NG911 or interim text-to-911 for the first device based on public safety profile information stored in a memory location of the IMS capable network;
• when the IMS capable network is capable of supporting the first device with NG911, directing the first request for the first emergency text message session to a NG911 enabled public safety answering point (PSAP);
• when the IMS capable network is incapable of supporting the first device with NG911 and is capable of supporting the first device with interim text-to-911, redirecting the first request for the first emergency text message session to a text control center (TCC);
• and
• when the IMS capable network is incapable of supporting the first device with each of NG911 and interim text-to-911, prompting a user of the first device to make a first 911 voice call.

A system for handling a request for an emergency text message session on an IP multimedia subsystem (IMS) capable network, the system comprising:

• one or more memories of the IMS capable network that store instructions for establishing the emergency text message session and store public safety profile information including locations on the IMS capable network that are capable of supporting next generation 911 (NG911) or text-to-911;
• one or more processors of the IMS capable network configured to execute the instructions stored on the one or more memories in response to the request from a device for the emergency text message session, where execution of the instructions cause the system to:
• determine a location of the device on the IMS capable network based on location information retrieved from a location server;
• identify a capability of the IMS capable network to support NG911 or interim text-to-911 for the device based on the public safety profile information stored in the one or more memories;
• when the IMS capable network is capable of supporting the device with NG911, direct the request for the emergency text message session to a NG911 enabled public safety answering point (PSAP);
• and
• when the IMS capable network is incapable of supporting the device with NG911 and is capable of supporting the device with interim text-to-911, redirect the request for the emergency text message session to a text control center (TCC) and establish a text-to-911 session, wherein the text-to-911 session is established only after determining that the IMS capable network is incapable of supporting the device with NG911.
