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.
Claims14
A method of creating a subscription entry in a subscriber database of an Internet-Protocol multimedia subsystem, which comprises:
- granting a subscriber access through an access network to the Internet-Protocol multimedia subsystem after securely identifying the subscriber by way of a unique access-network user identifier,
- transmitting by the subscriber the access-network user identifier in a register request of a session initiation protocol to the Internet-Protocol Multimedia Subsystem,
- transmitting, by an interrogating call session control function of the Internet-Protocol multimedia subsystem, the access-network user identifier to the subscriber database;
- determining, by the subscriber database, whether a subscriber entry including the access-network user identifier exists in the subscriber database;
- and
- upon verifying by the subscriber database that the subscriber is granted access through the access network to the Internet-Protocol multimedia subsystem, and upon determining that the subscriber entry including the access-network user identifier is lacking in the database, creating and storing by the subscriber database a subscription entry concerning the subscriber by creating a new pair of unique private and public identifiers.
A home subscriber server, comprising a processor 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 in response to the user registering for the first time at a access device for an Internet Protocol multimedia subsystem;
- search whether a subscriber entry including the access network user identifier is found in a home subscriber server database;
- upon determining that the subscriber entry including the access-network user identifier is lacking in the home subscriber server database, perform a check, based on the access network user identifier, whether the user associated with the access network user identifier is authorized by the access network to access the Internet Protocol multimedia subsystem;
- and
- create a subscriber entry by creating a new pair of unique private and public identifiers for the user upon determining that 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.
