Abstract: A control system (1) for a vehicle (10) with two axle drive devices (5, 12) has an engine control device (28) for controlling a first axle drive device (5) for driving a first axle of the vehicle (10) by a connected combustion engine (14) in a two-wheel drive mode and by a four-wheel drive mode. The control system (1) also has a control device (26) for controlling a second electric axle drive device (12) for driving a second axle of the vehicle in a four-wheel drive mode. The control device (26) is connected to the engine control device (28) for passing on at least one characteristic diagram to the engine control device (28).

Abstract: Method for identifying Internet users, comprising: identifying or authenticating an Internet user at the Internet access point in the course of an access check when using the Internet access service of an Internet Service Provider with whom the Internet user maintains a business relation; and after the Internet user successfully passed the access check adding Internet user identification information to an Internet user's IP message by the Internet access point prior to forwarding said IP message, guaranteeing the integrity of this information with cryptographic means.

Abstract: According to the inventive method, call back information is transmitted to a telephone network via an internet terminal using a click-to-dial service. In order to verify the information, the telephone network extracts internet terminal specific information from the access server via the internet. After comparing the call number information which is contained in the call back information and in the internet terminal specific information, the return call is initiated or suppressed. Return calls to subscribers who do not want to be called are thus suppressed.

Abstract: In one aspect, a method to for supporting services of an IP-based video network is provided. A plurality of subscribers of the video network registers with a presence server, each subscriber registers via an IP-capable terminal. The plurality of subscribers includes a first subscriber that logs onto the presence server when the terminal of the first subscriber is activated resulting in presence information being stored in the presence server. The first subscriber requests presence information about at least a portion of the plurality of subscribers which is provided to the fist subscriber.

Abstract: Short messages (SMS) or short messages containing images (MMS) are sent in a reliable, cost-optimized, and time-optimized manner to an IP-compatible terminal, e.g. a set-top box that is connected to a telecommunication network by expanding the functions of the distribution center for SMS/MMS messages and a registration entity for IP connections.

Abstract: In one aspect a system for transferring messages from a communication unit such as a phone, a cellular or mobile phone, a personal computer, a digital camera, or a digital video camera to other compatible systems such as digital set-top boxes, multimedia terminals, digital TV receivers or digital TVs is provided The system communication unit and a television device, by utilizing a base station in a wireless communications network, a communications provider connecting to the base station, a television network operator operating a television distribution network, and a television device.

Abstract: Method for identifying Internet users, comprising: identifying or authenticating an Internet user at the Internet access point in the course of an access check when using the Internet access service of an Internet Service Provider with whom the Internet user maintains a business relation; and after the Internet user successfully passed the access check aiding Internet user identification information to an Internet user's IP message by the Internet access point prior to forwarding said IP message, guaranteeing the integrity of this information with cryptographic means.

Abstract: There may be applications where for IN-calls, one SCP begins processing a transaction for supporting a service but another SCP continues processing said transaction. The invention shows how such a continuation of processing can be carried out in cases where this can be solved in terms of protocol.

Abstract: According to the invention, a conventional exchange centre is completed by an additional platform based on commercial hardware and software, whereon special modules whose functions can be controlled externally via open application programming interfaces (API) are implemented. Said platform also enables the development of added valued telephone services by the operators in a commercial software environment based on APIs for exchange centre functions.

Abstract: In an exhaust gas cleaning system, having a catalytic converter assembly that includes a storage catalytic converter (1, 10) for reducing nitrogen oxides, and a delivery device (2) for delivering a reducing agent to the inlet side of the storage catalytic converter (1, 10), it is proposed that in order to recirculate at least a portion of the exhaust gas flow leaving the storage catalytic converter (1), a recirculation line (3) be provided, in which an exhaust gas feed pump (4) can be disposed. The exhaust gas recirculation at the storage catalytic converter (1) during the regeneration phase reduces the oxygen content of the exhaust gas and as a result makes it possible to decrease the amount of reducing agent, such as fuel, delivered.

Abstract: The invention enables, in a simple manner, a telephone customer having an IP-based connection to the Internet via a personal computer (PC) to telephone, for instance, any public subscriber via said internet connection.

Abstract: New Internet-based services require the Internet user to be identified to a service provider. According to the invention, this requirement is met by the Internet access provider providing the IP-messages of the client, if desired, with data identifying the IP-packets of the Internet user. The Internet access provider guarantees the integrity of this data with cryptographic means.
