Abstract
The emergency location information gateway provides Public Safety Answering Points (PSAPs) with the capability to receive NG911-compliant (i.e., Session Initiation Protocol (SIP-based) and/or SIP-Voice over Internet Protocol (VoIP)) and other types emergency calls including embedded emergency location information and determine a physical location of a mobile or non-mobile target network device based on the embedded emergency location information. Conversely, a legacy network gateway (LGN) enables the conversion of traditional 911, and E911 calls into NG911 calls for transport and dissemination by so-called Emergency Services IP networks, or ESInets.
