1. A method for localization and location-related relaying of a subscriber in a Voice-over-IP network to an emergency center, wherein the subscriber may intermittently be registered at a location other than a home address of the subscriber, comprising:

  • providing the Voice-over-IP network with an address database;

    indexing addresses in the address database with location-related numbers and using a location-related number in the address database to indicate a current location of the subscriber;

    initializing the location-related number to identify the home address of the subscriber, wherein the home address at least identifies a city and a road;

    when the subscriber inputs a current address indicating that the current location of the subscriber is different from the home address, setting the location-related number to indicate the current address;

    at an expiration of a validity period of the current address indicating the current location, resetting the location-related number to identify the home address of the subscriber;

    routing an emergency call to an associated emergency center using the location-related number;

    transmitting the location-related number together with data from the subscriber to the associated emergency center; and

    ascertaining the current location of the subscriber making the emergency call using the location-related number by querying the address database.
