Abstract: 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.

Abstract: A mobile terminal device determines whether it is located in the local radio area of the network or in another radio area and the determined radio area is indicated to an application of the network. The application is used to control a communication request addressed to the mobile terminal device. Communication requests coming in on the network can be directly switched to the local radio area using the application or can be directly forwarded to the mobile radio address in the mobile radio network of which the mobile terminal device is located, thereby avoiding or substantially reducing roaming or forwarding of communication requests from the local radio area to another radio area and thereby achieving an economical operation of mobile telephone terminal devices with local radio area.

Abstract: The invention relates to a method for configuring electronic devices, particularly terminals, wherein during configuration at least parts of first configuration data on a chip card are fed to an electronic device, wherein the configuration data are stored on the chip card as second configuration data such that the stored data are the result of an obfuscation following at least one first algorithm. Furthermore, at least parts of the first algorithm can be derived by the electronic device. The stored second configuration data are subjected to a de-obfuscation by the device such that, having knowledge of the first algorithm, they can be reconstructed as first configuration data and the configuration of the terminal can be based thereon. The invention further relates to an arrangement having means for carrying out the method.

Abstract: A mobile terminal device (ME) determines whether it is located in the local radio area (HFB) of the network (MN) or in another radio area (FB2) and the determined radio area (HFB, FB2) is indicated to an application (APPL) of the network (MN). The application (APPL) is used to control a communication request (KV) addressed to the mobile terminal device (ME) by another network (FN) either to its local radio area (HFB) or to forward it to the other radio area (FB2) or the communication request (KV) is informed that the terminal device (ME) is not located in the local radio area (HFB).

Abstract: 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.

Abstract: There is described a Session Initiation Protocol (SIP) network entity for operating in a communications channel between a first SIP end point and a second SIP end point in a communication network. The first SIP end point has available a first set of communication features and the second SIP end point has available a second set of communication features, including at least one communication feature, for example Music on Hold, that is unavailable to the first SIP end point. The network entity acts as a client application for the first SIP end point and as a server application for the second SIP end point and is arranged to exchange signaling information with the SIP end points to enable the second SIP end point to utilize the at least one communication feature during communications with the first SIP end point.
