Abstract: The invention relates to a method for localization and location-related connection of a mobile voice-over-IP subscriber to an emergency call station even when the subscriber is temporarily registered in the voice-over-IP network with an address of a location other than his home address (2). For this purpose, the voice-over-IP network comprises an address database which is either configured as a central or decentralized database and in which addresses are indexed with a location-related number. An address of the location of the subscriber is updated (3) by using the address range predefined in the address database and an emergency call is routed (6, 7, 8, 9, 10) to an associated emergency call station using the location-related number. The location-related number and data of the subscriber are then transmitted to the associated emergency call station (8, 9).

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.
