1. A system for registering a terminal to an internet protocol multimedia subsystem, the system comprising:
- a terminal configured to send a registration request to an internet protocol (“
IP”
) multimedia subsystem, said registration request identifying the terminal by a session initiation protocol (“
SIP”
) end point that is associated with a multi-radio protocol gateway instead of a telephone number;
a multi-radio protocol gateway configured to connect a circuit-switched wireless access network of a public mobile core network to the IP multimedia subsystem, the multi-radio protocol gateway configured to;
set a private user identity for the terminal;
set a home network registrar domain name for the terminal, wherein the home network registrar domain name comprises either the domain name of the multi-radio protocol gateway or a numeric IP address for the multi-radio protocol gateway; and
establish a secure connection between the terminal and the IP multimedia subsystem; and
a register gateway configured to;
authenticate the terminal in the IP multimedia subsystem;
transmit a location update request corresponding to the new registration request to the home network registrar; and
perform a domain name service update in connection with the registering of the terminal in the IP multimedia subsystem.

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.

12. A system for establishing an integrated connection between a multi-radio protocol gateway and an internet protocol (“
- IP”
) multimedia subsystem, the system comprising;a multi-radio protocol gateway configured to; set a private user identity for a terminal connected to the multi-radio protocol gateway; set a home network registrar domain name for the terminal, wherein the home network registrar domain name comprises either the domain name of the multi-radio protocol gateway or a numeric IP address for the multi-radio protocol gateway; and register the terminal in the IP multimedia subsystem by creating and maintaining a secure and encrypted connection between the multi-radio protocol gateway and the IP multimedia subsystem, wherein the multi-radio protocol gateway is configured to create said secure and encrypted connection to the IP multimedia subsystem and relay, to the IP multimedia subsystem, the private user identity and the home network registrar domain name as parameters of the terminal, and wherein the multi-radio protocol gateway uses said parameters for creating and maintaining said integrated connection to the IP multimedia subsystem. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
