METHODS AND APPARATUS FOR INITIATING PROVISIONING OF SUBSCRIBER DATA IN A HSS OF AN IP MULTIMEDIA SUBSYSTEM NETWORK

摘要

A method of initiating the provisioning of subscriber data in at least a Home Subscriber Server of an IP Multimedia Subsystem network. The method comprises receiving an authentication request or Session Initiation Protocol message in respect of a given subscriber who is making use of a user terminal to access the IP Multimedia Subsystem network. If it is determined that subscriber data is not currently provisioned for the subscriber in a Home Subscriber Server function or receiving such a determination, the following steps are performed: 1) causing a first notification to be sent to the user terminal indicating that the registration attempt is rejected, and 2) sending a second notification to a subscriber provisioning system informing the provisioning system of the registration attempt.
