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： Techniques of emergency session handling in a communication network are provided, in which a packet switched network control function configured to handle emergency sessions established from a user equipment via a packet switched network access, e.g. an Emergency Call Session Control Function (E-CSCF), is associated with a switching control node of a circuit switched network. The switching control node is capable of handling emergency session established via a circuit switched network access, e.g. a Mobile Switching Center Server (MSC-S) of a mobile network. Handling of emergency sessions established via the packet switched network access is forwarded from the packet switched network control function to the associated switching control node.

摘要： A technique for performing a service domain selection in a communications network having a default service domain and at least one alternative service domain is described. According to this technique, a switching to the alternative service domain involves the invocation of a supplementary service that is provided as a supplement to a basic service. A method implementation of this technique comprises steps of identifying a basic service type associated with a service request; determining if for at least one of an originating side and a terminating side of the service request the identified basic service type is linked with a subscription to the supplementary service of service domain switching; and invocating the supplementary service of service domain switching if a linking can be determined.
