Abstract: The present invention proposes a solution for providing IMS services to users having circuit-switched controlled terminal being not adapted to provide IMS services to the users. In particular, it is proposed, in order to allow IMS to take the full call and service control, to place a user agent being responsible for the user ported to the IMS in a new node type called Mobile Access Gateway Control Function (MAGCF). This new node combines the logical functionality of a cellular switching center and the logical functionality of IMS. Further it is proposed to enhance a user's register, like HLR, to provide also information about the availability of a MAGCF node and about whether a particular user is enabled to use the MAGCF functionality.

Abstract: The invention provides a solution for registering a terminal having a packet-switched and circuit-switched functionality in a packet-switched service domain, such as the IMS over a circuit-switched access domain. In particular it is proposed to send a packet-switched registration message packed in a circuit-switched transport bearer (USSD) to a circuit node (HLR, MSC, dispatcher) which selects an adapter node (IA) being responsible for performing a registration in the packet-switched service domain on behalf of the user using the information provided with the packet-switched registration message and by deriving and adding additional information.

Abstract: A method for handling, by a ring node of a network having a ring topology, a data transfer of data packets through the network via which the data packets are transmitted to their destination node, wherein each ring node has two neighbouring ring nodes. The method includes detecting data packets of an incoming data transfer received from a non ring node to be transmitted through the network to their destination node. Furthermore, a ring direction is added to the data packets of the incoming data transfer, the indication indicating in which direction the data packets of the incoming data transfer are passed through the network having the ring topology. The data packets of the incoming data transfer are forwarded to one of the two neighbouring ring nodes based on the added indication.

A method aspect being performed in a roaming control entity comprises receiving at least one message related to the roaming operation, determining if a roaming attempt from the home network to the at least one visited network is performed, and, if the determining step is affirmative, requesting, from the home network, information relating to the UE so as to evaluate if the UE has access to the home network. The method aspect being performed in the UE comprises transmitting the at least one message about the roaming attempt, and receiving, responsive to the transmitting, deny or grant of access of the UE to the at least one visited network depending on whether the UE has access to the home network or not.
