Abstract:
Delivery of Next Generation 9-1-1 emergency services to an Internet Protocol (IP) Public Safety Answering Point (PSAP) is enabled using an existing or legacy selective router and Automatic Location Information (ALI) database. Using a protocol converting 9-1-1 messaging center according to the principles of the present invention, existing or legacy selective router equipment can provide Enhanced 9-1-1 (E911) over time division multiplex (TDM) circuits to non-IP capable PSAPs.
