In onse aspect, there is provided a method for the management of Application Server AS-related user data stored in a Home Subscriber Server HSS. In an embodiment, said method comprises a step of:

Management of application server-related user data

A method to improve the registration of 'Permanently Registered Users' (User1, User2, . . . User500) in an NGN-IMS subsystem. The permanently registered users are coupled to the IMS subsystem via a group device (AGW1, IP-PBX, SIP/H.323 GW) that is registered in the IMS subsystem as a dedicated IMS virtual user by means of its IMPI/IMPU identifier. The HSS/UPSF server is then allowed to download the user profiles in bulk. This results in fewer loads on the IMS and in a shortened start-up time of the group device(s).

Method to improve the registration of &#x3c;permanently registered users&#x3e; in an NGN-IMS subsystem

Method for registering a terminal with an application server being a member of a pool of available application servers in an IP Multimedia Subsystem, IMS, interconnected through a network, for providing services to the terminal, the method comprising: receiving a registration request from the terminal, selecting in accordance with a predefined set of rules comprising at least two rules, an application server for servicing a requested service to the terminal; and registering the terminal with the selected application server.
