摘要： Method, apparatuses and computer programs for handling data related to users of a communications system comprising: a database server storing data related to users of the system, and a plurality of service servers. The database server modifies (1103) a first data stored therein for a user according to a received request (1101), and sends a second message (1109) notifying the data modification to a first service server comprising: an identifier of the user, the first data after the modification, and an identifier of a second service server of the system that handle data related to the user. The first service server sends a third message (2105) to the second service server requesting to modify a data held therein in relationship with said user. Features of the invention help in reducing signaling in layered systems, since additional data are communicated in the second message.

摘要： The present invention proposes a solution for providing IMS services to users having circuit-switched controlled terminals. In particular, it is proposed, in order to allow IMS to take the full call and service control, to combine circuit-switched and packet-based multimedia functionality in a new node type called Mobile Access Gateway Control Function (MAGCF). In particular the present invention provides a method for ensuring that the MAGCF node acts as a roaming anchor point in order to enforce the handling of originating and terminating calls in the IMS.

摘要： 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.

摘要： A call to a dual mode user equipment is handled by using a further access network from cellular telecommunications access network. An indication of an incoming call to the user equipment is received in a control node that the device can be reached via a device using session initiation protocol (SIP) via the cellular telecommunication access network. The device using SIP sends messages to a device that transforms messages sent according to call control signaling protocol used in the cellular telecommunications network into messages according to SIP. A route to the SIP device is linked to a device that transforms user plane according to protocol in the cellular telecommunications access network into user plane according to internet protocol and vice versa.
