Distributed Emergency Text Message Architecture
First Claim
1. A distributed emergency text message architecture, comprising:
- an emedia aggregation gateway to receive an emergency text message initiated on an originating communications device; and
an emedia distribution server to convert said emergency text message, received from said emedia aggregation gateway, from an Internet protocol (IP) to a suitable message delivery protocol for delivery to a responsible recipient public safety answering point (PSAP) appropriate for a location of an emergency text messaging device initiating said emergency text message.

Abstract
An internet-protocol (IP) based distributed emergency text message architecture for providing reliable text to 911 services. The distributed emergency text message architecture distributes call routing and media transportation functionalities implemented in a conventional text to 911 solution over the following network entities: an emedia aggregation gateway, an emedia message broker, and an emedia distribution server. An emedia aggregation gateway, emedia message broker, and emedia distribution server each interconnect over an IP network to deliver emergency text messages directly to legacy public safety answering points (PSAPs). Uncoupling emergency services call routing and media transportation functionalities into multiple distributed elements absolves scaling issues associated with the conventional text to 911 solution. An emedia local gateway is preferably positioned on a PSAP in the distributed emergency text message architecture to eliminate the need for a selective router element when routing a teletype (TTY) message to a teletype (TTY) terminal on a legacy PSAP.
