Abstract
A network device performs a delayed registration in connection with phone call setup, if the network device does not know a phone number of a user in question at the time of updating the location updating. In addition, the network device performs user authentication and creates and maintains an encrypted and secure network connection between the network device and an IP multimedia subsystem by using data security mechanisms of a terminal of the IP multimedia subsystem and the authentication and data security parameters of the terminal received from the IP multimedia subsystem.
