Abstract

A requirement for an emergency call is to reach the nearest emergency call centre and to transmit information to said centre concerning the location of the caller. However, a pre-defined assignment of the subscriber number of the VoIP subscriber is not necessarily given, as a VoIP subscriber can use the telephone service from any Internet connection. To solve this problem, the emergency call service is implemented by the local VoIP service provider responsible in the roaming network of the VoIP subscriber.

Claims

1. A method for providing an emergency call service for VoIP subscribers, comprising providing

the emergency call service by a locally responsible VoIP service provider in the roaming network of the VoIP subscriber.

2. A method for providing an emergency call service for VoIP subscribers, comprising:

loading, on registration of a VoIP subscriber, an address of an emergency call server of a local VoIP service provider and information relating to a physical Internet connection via which the registration is taking place, in a VoIP client of the VoIP subscribers;

placing a call the emergency call server, based on the address, when the VoIP client recognizes a received call number based on preconfigured list as an emergency call number, with the call including the position information; and

accepting the received call of the VoIP client by the emergency call server as an emergency call, and passing on to an emergency call center which is responsible for an area of the emergency call server.
