A method for decreasing a Call Setup Time Key Performance Indicator (CST KPI) of an Internet Protocol (IP) multimedia call in a mobile telecommunications network includes: initiating the IP multimedia call from an originating user equipment (UE) to a terminating UE; transmitting a session initiation protocol (SIP) call initiation message from the originating UE to a terminating Proxy-Call Session Control Function (P-CSCF) through an originating Serving-Call Session Control Function (S-CSCF); and creating a wake-up message via a network element upon receiving the SIP call initiation message. The wake-up message bypasses a plurality of network application servers (ASs) to start switching a transition of the terminating UE from an idle state to a connected state before the SIP call initiation message reaches the terminating P-CSCF.

A cladding tube for nuclear fuel made from metal and including concave dimples on its external surface. A nuclear fuel assembly includes at least a plurality of nuclear fuel rods provided with such cladding tubes. The cladding tube is advantageously manufactured by pilgrim rolling, the dimples being formed during the pilgrim rolling.

A conference condition file is used to check whether at least one stored conference condition is met, which indicates a condition regarding a participant's setup of and/or participation in the telecommunication conference. If at least one condition is met then the conference is set up or the participant is added to the conference.

Method for automatically setting up and/or controlling a telecommunication conference

A method for establishing a communication connection includes transmitting an identification for identifying a first communication device to the first communication device or a second communication device via a packet-switched first communication connection between the first communication device and the second communication devices, and using the identification to establish a circuit-switched second communication connection between the first communication device and the second communication device.

Method for establishing a communication connection and communication device

The communication device has three useful data transmission states, where the communication device in the first and in the second state has associated first communication resources and in the third state has associated second communication resources, with the second communication resources being fewer than the first communication resources. Provision is made for there to be state changes from the first state to the second state, from the second state to the third state, from the third state to the first state and from the second state to the first state.

Apparatus method and computer program element for efficient control and supervision of the activity of a communication device

A communication system in which a communication service client terminal specifies a criterion, with further communication service client terminals which meet the criterion being able to be participants in a communication service which is provided. A server computer is configured to produce a list of the further communication service client units which meet the criterion and to transmit the list.

Management of dynamic groups in a communication system

A waste heat steam generator including evaporator tubes is provided. The evaporator tubes are connected in parallel on the flow medium side, a plurality of overheating tubes are mounted downstream of the evaporator tubes using a water separation system. The water separation system includes water separation elements, each water separation element being respectively mounted downstream of the plurality of evaporator tubes and/or upstream of a plurality of overheating tubes. Each water separating element includes an inlet pipe which is respectively connected upstream to the evaporator tubes, the inlet pipe extending into a water evacuation pipe when seen in the longitudinal direction. A plurality of outflow pipes branch off in the transitional area, the pipes being connected to an inlet collector of the overheating tubes which are respectively connected downstream. A distribution element is arranged on the steam side between the respective water separating element and the inlet collector.

Message traffic between a communications unit and a first network unit of a mobile radio system, initiated by an SIP control message, is monitored. The SIP control message is evaluated by a second network unit by using at least one analysis parameter and an analysis result is generated therefrom. The analysis result is used for generating at least one item for utilization information of the first network unit that monitors the message traffic between the communications unit and the first network unit.

Method for monitoring message traffic, and a first and second network unit for the execution thereof

To register a communications device (UE) in a communications network (CN), one or more temporary communications addresses (NI, NI) are negotiated between the communications device (UE) and at least one registration unit (AV) of the communications network (CN), the temporary communications addresses being valid only for a predeterminable utilization period (ZT, ZT). The temporary communications address (NI) concerned is registered by the registration unit (AV) for this utilization period (ZT).

Method for registering a communications device, and an associated communications device and registration unit

Disclosed is a steam generator pipe which can be produced in a simple and economical manner and which has a particularly good heat transitional behavior having a large band width with various operational conditions. According to the invention, at least one insert is arranged in the inner chamber of the pipe in order to form a swirl-generating inner profile. The insert comprises a plurality of wires which wind, in a screw-like manner, along the inner wall of the pipe in the form of a multi-path thread.

Media data from a first communication session and media data from a second communication session are received by a unit in the communication network and are combined therein to form at least one combined media data stream which contains the media data from the two communication sessions. The combined media data stream is sent to the communication terminal.

Method and apparatus for transmitting media data

A conference communication system including a conference server which provides a conference for a first and a second communication terminal, a notification device which generates a notification message according to a media data transmission control protocol which is used for signaling whether media data sent out by the first communication terminal have been forwarded to the second communication terminal.

Conference communication system and method with notification

A mobile radio communication system, which has a communication network and at least one user terminal, which communication system has a memory apparatus which is set up to store, upon clear-down of a radio link using at least one physical channel between the user terminal and the communication network, values for parameters which specify properties of the at least one physical channel from the radio link; a loading apparatus which is set up to load stored values for parameters which specify properties of at least one physical channel from a radio link; and a control apparatus which is set up to control the setup of a radio link between the user terminal and the communication network on the basis of parameter values loaded using the loading apparatus.

Communication system

A push-to-talk communication system is described in which a decision unit (chair) and/or a queue are provided for allocating the right to talk during a push-to-talk communication, and corresponding control messages, request messages and information messages are transmitted.
