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.

Application server for managing communications towards a set of user entities

A method for providing a roaming functionality related to an Internet Protocol Multimedia Subsystem (IMS) session includes: transmitting, by a second IMS domain, a session set-up request control signaling to a first IMS domain; transmitting, by the first IMS domain, the session set-up request control signaling in a forward direction to a Roaming Border Control Function (RBCF); and handling, by the second IMS domain, the user plane path and the associated control signaling to terminate the session set-up. Local break out of media is applied for the roaming first UE. The RBCF provides a linking of signaling received via a loop through the first IMS domain in the Home Public Land Mobile Network (HPLMN) with media anchored due to the local break out in the second IMS domain in the Visited Public Land Mobile Network (VPLMN).

Method for usage of VPLMN infrastructure by an HPLMN to terminate an IMS session set up for a roaming user

The invention relates to a method for transmitting control data in a telecommunication network for controlling a service administered by the telecommunication network, especially a server connected to the telecommunication network. According to said method, the telecommunication network provides a data object, especially a contact of an address book, with a function that is special with respect to other data objects. A parameterized message is transmitted by the terminal device for telecommunication via the telecommunication network to a higher order system component of the telecommunication network, said message comprising at least one first parameter for characterizing the data object and a second parameter containing a control information, especially for the activation, deactivation or modification of the service. The higher order system component checks at least one of the parameters and the service is controlled depending on the result of the check and in accordance with the control parameter.

Method for transmitting and negotiating network-controlled functional data between a client and a server

The invention relates to a method and a system for controlling an arrangement of a configuration comprising two or more user devices (multi-device configuration) of telecommunication user devices in a public telecommunication network. According to the invention, the supplementary services of the public telecommunication network associated with the first user device or with an identification chip connected to the first user device are activated in such a manner that changes of the supplementary services are effective in the other user devices or the identification chip connected to the respective additional user device of the multi-device configuration at the same time or with a temporal delay. In this manner, when one or more parallel calls are switched to one or more user devices of the multi-device configuration, before delivery of the call, the kind of the call request resulting in a reservation of resources required for completing the call, the system states of the user devices to be called or of or of the identification chips connected to the user devices and the exchange devices involved therein are determined using an intelligent call control and the call can be delivered in a resource-saving manner.

A method for controlling the delivery of messages in a telecommunications network, particularly in a mobile communications network, with data assigned to a subscriber relationship and to a terminal, that is, to the identification chip (for example, GSM, SIM, UMTS, USIM) connected thereto. These assigned data, entirely or in part, are transmitted synchronously or approximately synchronously to additional terminals, that is, to the identification chip (for example, GSM SIM, UMTS USIM) connected thereto, assigned to this subscriber.

Method for controlling the delivery of messages in a telecommunications network while taking multi-device configurations into special consideration

A method for call establishment and for the accounting of calls in telecommunications networks wherein specified destination call numbers are stored in a database situated in a service node of a communications network and the database can be accessed by a subscriber by dialing a service identification number.
