Abstract: The invention relates to a method for operating a navigation system for a motor vehicle in a road network, and to a navigation system. To this end, first a zone of the road network is provided with an emissions class-dependent drive-through restriction, wherein the motor vehicle is associated with at least one emissions class. First, information about the geographical location of the zone and about the emissions class at least required there is stored in the navigation system. Then, information about the at least one emissions class of the motor vehicle is entered into the navigation system. Thereafter, the information entered is considered in the destination guidance process, wherein destination guidance into or through the zone is avoided if the at least one emissions class of the motor vehicle is affected by emissions class-dependent drive-through restrictions in the zone.

Abstract: After the input of a subscriber (TLN1) of the first terminal (EG1), a connection to a temporarily available voice memory (SPS) is signalized by the same, and subsequently a voice message (spn) and at least one piece of retrieval information (ai) identifying the second terminal (EG2) is transmitted and stored at that location. Subsequently, the connection is terminated and the second terminal (EG2) is informed of the presence of a retrievable voice message (spn) in the voice memory (SPS) via the voice memory (SPS) by means of the at least one piece of retrieval information (ai), and the voice message (spn) can be retrieved from the second terminal (EG2) by means of the transmitted retrieval information (ai), or is transmitted to the second terminal (EG2) by the voice memory (SPS). In this manner voice messages (spn) can be stored for terminals (EG2) and retrieved by the same, regardless of whether one or no voice memories—such as an answering machine—is associated with these terminals (EG2).

Abstract: For alternate operation of a terminal (EG1) at at least two communication nodes (GK1, GK2), the terminal (EG1) is first registered with a first of the communication nodes (GK1). In this case, registration is followed by there being a logical connection between the terminal (EG1) and the first communication node (GK1). The obtainability of the first communication node (GK1) is monitored, and in the event of the first communication node (GK1) being unobtainable a status information item relating to the unobtainability is produced, and the status information item is taken as a basis for setting up a logical connection between the terminal (EG1) and the second communication node (GK2). The terminal (EG1) is then automatically operated at the second communication node (GK2).

Abstract: In order to operate a communication terminal for packet-oriented data transmission, at least one piece of status information is stored, for a communication terminal, in a memory unit associated with the communication terminal. Said status information is provided with a digital signature that is calculated from the status information by means of a private key for an asymmetrical encoding method associated with a first control unit associated with the communication terminal, for the resolution and/or conversion of network addresses. If the first control unit fails, a request is transmitted comprising the status information and the digital signature to associate the communication terminal with at least one second control unit, and the digital signature is checked. In the event of a positive check result, the communication terminal is associated with the second control unit.

Abstract: After an emergency call from a communication terminal has been received by an emergency call center, the position of the communication terminal is determined by querying a database. An area around the position of the communication terminal is defined as danger area and other communication terminals located in the danger area are identified. Communication terminals of rescue workers in the danger area who are to be informed are then selected. Finally, emergency information is generated, which can, for example, contain information about escape routes for potentially imperiled persons or access route information for rescue workers. This emergency information is then communicated to each of the selected communication terminals of potentially imperiled persons and/or rescue workers.

Abstract: Conference participants are selected via a network element in a network, the geographical area locations, for example, buildings of an enterprise, of the conference participants are determined and depending on the determined locations a geographical conference area, for example a conference room is determined for each conference participant. The conference area together with the conference information is communicated to the conference participants. The availability of the conference participants can be checked for the communication.

Abstract: The geographical position, or measured information from which the geographical position may be deduced, of a mobile terminal is determined via requests to the terminal and positional information or measured information transmitted to a control device. The speed of displacement of the mobile terminal is determined from the transmitted positional information or measured information and the frequency of requests controlled depending on the determined speed of displacement of the mobile terminal. The communication exchange, in particular, for mobile terminals with low speeds of displacement is therefore significantly reduced and the mobile terminals and central devices provided with dynamic load reduction.

Abstract: First information and second information is stored in the communication system for a callback after a first communication terminal attempts a call to a second communication terminal in which the connection is not established. The first information allows the second communication terminal to display the attempted call so that a callback to the first communication terminal can be executed on the part of the second communication terminal. The second information includes a charge type for the callback correlating at least to the attempted call.

Abstract: A mobile device which is assigned to a person transmits an identification to a central device where localization of the mobile device is initiated. After the mobile device has been located in an area of an access system, the identification is checked for authorization for access via the access system. Access via the access system is either allowed or denied based on the result of the check. Access by an authorized person to secure areas or devices with the aid of a wireless device which is usually carried along—for example a mobile radio terminal or a DECT terminal—thus becomes considerably easier and more convenient.
