System and method for providing network assisted geographic coordinates for emergency data messaging

摘要

A system and method for communicating geographic coordinates with an emergency data message to a public safety answering point (PSAP) may include receiving a request from a user to send an emergency data message to a PSAP and determining whether geographic coordinates are locally available. If geographic coordinates are locally available, then the locally available geographic coordinates may be obtained and included with an emergency data message. Otherwise, if the geographic coordinates are not locally available, then a request for geographic coordinates from a network node on a communications network may be made and received from the communications network for inclusion with the emergency data message. The emergency data message may be communicated to a network node on the communications network for routing to the PSAP.

1. A method for communicating geographic coordinates with an emergency data message to a public safety answering point (PSAP), said method comprising:
receiving a request from a user to send an emergency data message to a PSAP; determining whether the emergency data message is actually an emergency message by inspecting at least one data field indicative of the data message being an emergency message, wherein the at least one data field includes an abbreviated dialing code for indicating different types of emergencies; in response to determining that the emergency data message is an emergency message, determining whether geographic coordinates are locally available; if so,
obtaining the locally available geographic coordinates; andincluding the geographic coordinates in an emergency data message; otherwise,
requesting geographic coordinates from a network node on a communications network;receiving the geographic coordinates from the communications network; andincluding the geographic coordinates in an emergency data message; based on the inspection of the abbreviated dialing code, initiating continuous geographic coordinate updates to the PSAP if the abbreviated dialing code indicates a particular type of emergency; and communicating the emergency data message to a network node on the communications network for routing to the PSAP.
