Abstract: A method for mobile radio suppliers to provide or share or jointly use a mobile radio access network is provided. Said method is characterized in that a single radio access network (9; 12), which is operated according to UMTS standard, cdma2000 standard, or GSM standard, for example, is jointly used by several mobile radio suppliers. In order to do so, the mobile radio networks comprise a common radio access network but separate core networks. Preferably several PLMN IDs are transmitted by the common radio access network and are made available to the user terminal for selection. The inventive method allows a joint radio access network to be made accessible to different mobile radio suppliers, a mobile radio user selecting one of several transmitted preferably PLMN IDs and using services (CS or PS) via the associated core network of the selected mobile radio operator.

Abstract: A method for the display of standardized Internet pages (for example, in HTML or XML standard), generated for display on large-size screens, on a small display on hand-held devices (mini-computer, PDA or mobile radio device) is disclosed, in which the hand-held device can be provided with a mobile radio connection to the internet. A virtual large image memory is maintained in the device. Within the large virtual image the device display can be freely displaced as a readable image section. A zoom function permits an overview and coarse positioning of the detailed representation. The detailed representation can be continuously moved around within the virtual image in the form of a screen section by means of a pointer device (mouse pointer) by moving the mouse pointer to the display edge (and beyond). Switching can be performed at any time between the display modes.

Abstract: The invention relates to a method and a system for controlling an arrangement of a configuration comprising two or more user devices (multi-device configuration) of telecommunication user devices in a public telecommunication network. According to the invention, the supplementary services of the public telecommunication network associated with the first user device or with an identification chip connected to the first user device are activated in such a manner that changes of the supplementary services are effective in the other user devices or the identification chip connected to the respective additional user device of the multi-device configuration at the same time or with a temporal delay.

Abstract: A method and device for operating MIMO air interfaces in mobile communications systems, according to which a radio signal is transmitted by a transmitting device via a MIMO channel comprising a number of m subchannels and is received by a receiving device having n antennas. Different polarizations are assigned to the signals to be transmitted on the subchannels, and the signals are supplied to a common antenna.

Abstract: The invention relates to a method and a system for controlling an arrangement of a configuration comprising two or more user devices (multi-device configuration) of telecommunication user devices in a public telecommunication network. According to the invention, the supplementary services of the public telecommunication network associated with the first user device or with an identification chip connected to the first user device are activated in such a manner that changes of the supplementary services are effective in the other user devices or the identification chip connected to the respective additional user device of the multi-device configuration at the same time or with a temporal delay.

Abstract: A method couples online and Internet services. Previously, personalized services in particular (e-mail etc.) are only available from Internet service providers via the telecommunications network and RAS/RADIUS access and not via the public Internet. Now the ISP is equipped with an open Internet application platform (OIA) coupled so that the ISP customer can take advantage of an extended range of services compared to usual Internet customers, even during access via the Internet. The method permits e-mails to be re-directed from the ISP server with a known address to the OIA platform, in such a way that the customer can use these services world-wide via the public Internet using any terminal via any network. One example is the use of a T-Online e-mail account from the fixed network and mobile telecommunications network, from home, at work and while travelling via foreign telephone networks and local and foreign company networks/LAN access.

Abstract: A method for controlling the delivery of messages in a telecommunications network, particularly in a mobile communications network, with data assigned to a subscriber relationship and to a terminal, that is, to the identification chip (for example, GSM, SIM, UMTS, USIM) connected thereto. These assigned data, entirely or in part, are transmitted synchronously or approximately synchronously to additional terminals, that is, to the identification chip (for example, GSM SIM, UMTS USIM) connected thereto, assigned to this subscriber.

Abstract: The invention relates to a method for dimensioning hardware components for base stations of CDMA communication networks, especially hardware components of a UMTS base Station (node B). The number of hardware components, that is Channel elements (CE) and modems (M), required for the individual base stations in order to maintain a defined blocking probability, is determined on the basis of the spatial traffic distribution and a CDMA network comprising base stations.

Abstract: A method for testing SMS connections in mobile communication systems with automatic interchange of one or more SMS messages or SMS dialogs between a test device and at least one remote location and having complete tabular recording of the SMS message contents and protocols emitted from the test device (MO) and arriving at the test device (MT).
