Abstract: A computer-implemented apparatus and method for communicating partial notifications relating to a presentity's presence information. The communication may be effected between presence servers and terminals coupled to the presence servers via a network. At least one presentity is identified to which a terminal has requested presence services. A presence document is created, where the presence document includes presence information corresponding to the presentity. The presence information is configured as partial presence information comprising less than a total of the presence information available for the presentity. The presence document having the partial presence information is communicated to the terminal requesting the presence information.

Abstract: According to the present invention a method and an apparatus in a packet-switched network for supplying data packets to receivers (4a-c) belonging to a multicast group are disclosed. The apparatus comprises a routing means (2) for receiving data packets from a sender (1) and for buffering data packets the destination address of which is a multicast address of a multicast group. The apparatus further comprises a control means (3) communicating with the routing means (2) for determining the addresses of the receivers (4a-c) of the multicast group indicated by the multicast address and receiver-specific parameters, for designating filters for each receiver (4a-c) and/or each determined receiver address in accordance with the receiver-specific parameters and for supplying the determined addresses and designated filters to the routing means (2).

Abstract: According to the present invention, a plurality of data packets are received and routed by a router (1) in a data network. The router (1) comprises storing means (11) for storing a pre-defined list of rules for detecting special data packets, detecting means (12) for detecting special data packets in the received plurality of data packets on the basis of the pre-defined list of rules stored in said storing means (11), and routing means (13) for requesting instructions for the special data packets detected by said detecting means (12) and for routing the special data packets in accordance with instructions received on request. According to the present invention, an advanced service architecture for next generation network services is provided. In this service architecture, the functions of the detecting means (12) and the routing means (13) can be achieved by a service trigger and a service logic, respectively.

Abstract: The invention relates to a communication method and system wherein a network element of a roaming user is attachable to a visited first network and may still be served by a serving means of the home network. The network element of the roaming user is able to indicate a preference, e.g. home or local control, when registering or initiating a connection. A network element of the visited network such as proxy means adds information on the indicated preference when sending a message to the home network. The message is preferably sent as a protocol message, in particular a message of the Session Initiation Protocol (SIP).

Abstract: A communications system and method for providing services to a subscriber of the system is provided. The system includes a system element controlling call processing, service data for a subscriber of the system, and an element for storing subscriber data. The system is configured to associate an indicator with a service data structure of the service data of a subscriber. The element for storing subscriber data is configured to store the service data structure of the service data of the subscriber associated with the indicator. The system is configured to transmit from the element for storing subscriber data service data of a subscriber comprising the service data structure associated with the indicator to the system element controlling call processing service.
