Abstract
Official abstract text for this publication.
An SS7-based call protocol conversion gateway that translates between circuit-switched SS7 protocols and session initiation protocol (SIP) oriented protocol, allowing an E911 call initiated over a switched network to be routed by a VoIP network. The SS7-based call protocol conversion gateway provides a PSAP with MSAG quality (street address) information about a VoIP dual mode phone user without the need for a wireless carrier to invest in building out an entire VoIP core. Thus, wireless carriers may continue signaling the way they are today, i.e., using the J-STD-036 standard for CDMA and GSM in North America, yet see benefits of a VoIP network core, i.e., provision of MSAG quality location data to a PSAP.
First claim
Opening claim text (preview).
1 . (canceled) 2 . A method comprising: converting, by a conversion gateway, a Voice Over Internet Protocol (VoIP) call into an Signaling System Number 7 (SS7) based call; transmitting, from the conversion gateway via Session Initiation Protocol (SIP) call signaling associated with the VoIP call, a request to a VoIP positioning center for routing information associated with the VoIP call; receiving, at the conversion gateway, routing information associated with the VoI…
