Currently, text communication cannot be used to ask for help in emergency situations. Even in the Next Generation 9-1-1 system, an IP/SIP-based emergency communication system, there has been no investigation into how text communications such as Instant Messaging (IM) and Short Message Service (SMS) can be integrated. The authors identify the technical challenges in the integration of IM and SMS net-works with the NG9-1-1 system, and propose a solution for each challenge. The authors also describe a working prototype system using the approach.
