Abstract: A system includes a terminal, a wireless access network, an IP telephony network, a core network gateway from the IP telephony network to the public mobile phone network and a network device, which connects the wireless access network to the IP telephony network and adapts the IP telephony network services to be used by utilizing the circuit-switched signaling protocols of the terminal. A location updating request is received from the terminal over the wireless access network. Location updating is performed via a core network gateway. The network device performs user registration to the IP telephony network using a domain name formed by the phone number of the user and the domain name of the network device or the numeric IP address as the address connection to be registered and as location data in the IP telephony network.

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.

Abstract: A system includes a terminal, a wireless access network, a multimedia core network and a network device, which connects the wireless access network to the multimedia core network, expanded location updating to the registration procedure of the multimedia core network, and performs double registration of the user to the multimedia core network. The terminal performs expanded location updating relaying the registration point identity of the multimedia core network, the user's phone number and the private user identity to the network device in connection with normal location updating signaling. In the double registration performed by the network device, two addresses are registered for the user of the terminal, one of which is associated with the domain name of the terminal in question or a numeric IP address, and the other to a domain name of the network device or a numeric IP address.

Abstract: A multi-service mobile station according to the invention comprises means (42) for connecting the device by radio to telecommunication network in order to utilize typical mobile station services, such as speech and data services. Additionally, the multi-service mobile station provides means (41, 40, 47) for using various information processing services (P1, P2), such as telefax service and electronic mail service. When using information processing services, the information processed by the user is automatically saved in the memory means (40, 47) of the multi-service mobile station when a certain criterium is met. The criteria are e.g. shifting from one service to another, going over to current saving mode, or, in a two-section multi-service terminal device, folding the device together.
