Abstract
A method for self-provisioning of subscriber data allows efficient registration of a subscriber for an Internet-Protocol Multimedia Subsystem of a telecommunication network at the subscriber database of the Internet-Protocol Multimedia Subsystem. A subscription entry is created in the subscriber database of the Internet-Protocol Multimedia Subsystem of a telecommunication network, based on prior secure identification of the subscriber by the access network that grants access to the Internet-Protocol Multimedia Subsystem.

A method of creating a subscription entry in a subscriber database of an Internet-Protocol multimedia subsystem that is reached by a subscriber through an access network, and the access network grants access to the Internet-Protocol multimedia subsystem after access network has securely identified the subscriber by way of a unique access-network user identifier, the method which comprises:
- transmitting the access-network user identifier in a SIP Register request from the subscriber to the Internet-Protocol Multimedia Subsystem, transmitting the access-network user identifier from an I-CSCF of the Internet-Protocol Multimedia Subsystem to the subscriber database;
- and
- creating and storing with the subscriber database a subscription entry concerning the subscriber if no subscriber profile for the specific subscriber exists yet.
A home subscriber server, comprising a device configured to:
- receive a location query request for a user;
- retrieve from the location query request an access network user identifier relating to the user;
- search whether a subscriber entry associated with the access network user identifier is found in a home subscriber server database;
- if no subscriber entry is found in the search, perform a check, based on the access network user identifier, whether or not the user associated with the access network user identifier is authorized by the access network to access an Internet Protocol multimedia subsystem;
- and
- create a subscriber entry for the user if the result of the check shows that the user associated with the access network user identifier has been authorized to access the Internet Protocol multimedia subsystem.
