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). The actual location of the subscriber emitting the emergency call is then determined in the emergency call station using the location-related number and querying the address database (11). The concept underlying the invention is to provide, in a simple manner and without major modifications to the voice-over-IP network, location-related information for voice-over-IP subscribers for the routing of emergency calls or for determining the actual location of a voice-over-IP subscriber.
