Embodiment Construction

[0047] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0048]The present invention mainly proposes a solution for E110 VoIP (Voice over IP) user location information. In this solution, a call from a VoIP device, together with the correct location information of the device and the call-back number, can be routed directly to the appropriate PSAP (Public Safety Answer Point, Public Safety Answering Point). Each LATA (Local Access and Transport Area, local access and transmission area) has at least one VoIP gateway. The VoIP gateway performs local execution, accepts the inbound VoIP gateway packet data, and converts it into a wired standard voice call. The voice call will be output to an optional routable voice port. The public safety answering point can use the ESLK (Emergency Service Location...

Abstract

The invention discloses an emergence call location method of a VoIP (Voice over Internet Protocol) user and a system, which comprises IP (Internet Protocol) equipment, an VoIP exchanger, an application server, a location server at a service bureau end, a gateway controller, a VoIP gateway, a selective route, a public safety response point and an automatic location identifying database, wherein the IP equipment is connected with the VoIP exchanger, the VoIP exchanger is connected with the application server, the application server, the gateway controller, the VoIP gateway, the selective route, the public safety response point and the automatic location identifying database are sequentially connected, the application server is connected with the location server of the service bureau end, and the location server is connected with the automatic position identifying database. By the invention, the call from the VoIP equipment, the correct location information of the VoIP equipment and a callback number can be directly routed to the proper public safety response point. The invention helps a public safety response processing end to quickly and correctly locate the location of the VoIP user.

Description

technical field [0001] The invention relates to a positioning method and system, in particular to a VoIP user emergency call positioning method and system. Background technique [0002] Today, Internet telephony (VoIP) market is becoming more and more popular as a less expensive alternative form of traditional telephony services. Internet telephony, however, presents similar challenges to wireless devices in providing location information to emergency dispatchers. Currently, if an emergency services number is dialed through a commercial VoIP service, depending on how the VoIP provider handles such calls, the call can be routed to an answering pick-up point designated by the operator, or the call can be routed to a bill with the caller or the non-emergency number at the public safety answering point associated with the service address. Because a VoIP adapter can be plugged into any Internet connection with sufficient bandwidth, the caller can actually be hundreds or even th...
