Abstract: An application server for managing communications towards a set of user entities, the set of user entities having a first user entity. The application server includes a receiver for receiving a first session initiation request, the first session initiation request having a public identification identifying the set of user entities, a processor for assigning a first user identification to the public identification, the user identification identifying the first user entity, and a transmitter for transmitting a second session initiation request to establish a communication link towards the first user entity, the second session initiation request including the first user identification.

Abstract: The invention relates to a method for establishing a communication link between a communication system and a remote station by means of a communication network, whereby, in the context of the communication link, a parameterized selection of a remote station is made from several available remote stations by utilizing the name resolution mechanism. The communication forms a logical name with the help of parameters used for selecting a remote station or embeds the parameters in a logical name and transmits the formed logical name to a name resolution mechanism located in the communication network. The name resolution mechanism selects a remote station on the basis of the afore-mentioned logical name and a selection function and feeds back the communication address thereof.

Abstract: A common communication network with line- and packet-switching control is provided, with telecommunication services such as call-forwarding, being carried out by means of a link between a control device and a communication network. At least partially synchronized control is provided for both the line-switching and the packet-switching part of the communication system, and carries out the telecommunication services.

Abstract: The invention relates to a common communication network with line- and packet-switching control, with telecommunication services such as call-forwarding being carried out by mean of a link between a control device and a communication network. The invention is characterized in that at least partially synchronized control (19) is provided for both the line switching (2) and the packet switching part (1) of the communication system, and carries out the telecommunication services.
