FIELD: radio engineering, communication.
SUBSTANCE: invention relates to a method and apparatus for provisioning subscriber data in IP multimedia subsystem network nodes. The technical result is achieved through a method which involves receiving an authentication request or session initiation protocol message with respect to a given subscriber using a user terminal to access the IP multimedia subsystem network, and if it is determined that subscriber data are not currently provisioned for the subscriber in the functional block of a subscriber data server, or if such a determination is made, the following steps are carried out: 1) causing a first notification to be sent to the user terminal indicating that a registration attempt is rejected, and 2) sending a second notification to a subscriber provisioning system informing the provisioning system of the registration attempt.
EFFECT: dynamic provisioning of subscriber data to a plurality of IP multimedia subsystem network nodes.
