In one aspect, a method for realizing a presence service with a buddy list that can be displayed on a display device of a terminal is provided. In an activated state, the buddy list itself is displayed, and in a deactivated state, the buddy list itself is not visible. The buddy list is updated by a control device during a change in state of at lest one subscriber to be monitored and/or of at least one device assigned to the subscriber. According to the invention, the updating of the buddy list ensues in the deactivated state by means of the control device while using a method other than one used in the activated state.

There is described a localization system with a mobile position data transmitter having a position-detecting device for detecting a position of the position data transmitter and for deriving position data from the position detected. The position data transmitter also has a radio tag writing device for wirelessly emitting the derived position data with a write signal for writing to radio tags. The localization system also has radio tags which are to be spatially distributed and each have a memory for storing an item of localization information which is taken from the position data received with the write signal. A radio tag reading device is used to retrieve and output the stored read information from the radio tags that are situated in the retrieval range.

There is described a system for switching from an established media path to a new media path for packets transmitted between first and second end points in a packet based network. An instruction is transmitted to the first end point instructing it to set up a new receiving channel for receiving packets transmitted from the second end point over the new media path. An instruction is transmitted to the second end point instructing it to configure a sending channel to send packets over the new media path for reception on the new receiving channel of the first end point. For a time period during the switching, the first end point monitors for packets simultaneously on both its new receiving channel and an established receiving channel configured to receive packets transmitted from the second end point over the established media path. This systems helps ensure a seamless switchover from the established to the new media paths.

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.

In one aspect, a method for managing documents or partial documents in an electronic document folder is provided. A validity indication, which is individual to the document or partial document and specifies a validity expiry time is assigned to a respective document, e.g. an e-mail, or a partial document, e.g. an e-mail attachment and is stored, the indication being assigned to an executable validity program. Once the validity expiry time has been reached, the executable validity program, assigned to the validity indication, is executed for the document or partial document with an assigned validity indication. The executable validity program comprises a deletion routine for deleting the document or partial document with the assigned validity indication in the electronic document folder.

The invention relates to a transport apparatus for a vibration compactor that comprises an axle with a wheel being arranged on each of its ends. The transport apparatus of the invention is advantageous, because it does not require any reconfiguration work, special tools or other special measures for transporting the vibration compactor.

A method for transmitting on-demand software and/or data from a server to a terminal in a packet network is provided. According to the method, a bandwidth test is performed as a prerequisite for transmission, said test verifying whether the currently available bandwidth is sufficient for transmitting the requested software or data. The server does not transmit the requested software or the requested software or the requested data if the results of the bandwidth test is negative.
摘要:
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).
