Abstract:
1. A method for routing an emergency data message to a public safety answering point (PSAP), said method comprising: receiving at a mobile switching center a pre-established emergency data message package generated by activating a single emergency data message button, said emergency data message package comprising: routing the emergency data message package to an originator data message service controller; processing the emergency data message package at the originator data message service controller to determine, based upon the presence of the abbreviated dialing code that the emergency data message package is an emergency message requiring communication to a PSAP and not a standard data message; communicating the abbreviated dialing code to an emergency data message short code database; returning an emergency data message short code from the emergency data message short code database to the originator data message service controller, which emergency data message short code is indicative of a type of emergency data message; prioritizing the processing of the emergency data message package based upon the presence of the emergency data message short code; selecting a PSAP local to the user to send the emergency data message; sending the emergency data message to the selected PSAP; initiating continuous geographic coordinate updates to the PSAP from the originator data message service controller based upon the determined type of emergency data message; and validating that the pre-established emergency data message package has been transmitted without error with a checksum algorithm.
