Abstract: A transaction method between a client and a terminal (2) connected to a telecommunication network comprises the transmission of at least one client identification (IDUI), a terminal identification (POSID), and transaction-specific data to a financial server connected to the telecommunication network.

Abstract: The present invention relates to a call-back method for telecommunications and to devices adapted accordingly, wherein a first subscriber with a first communication end device (A) that preferably comprises a SIM-card, indicates to a telecommunication system that he wants to communicate with at least a second subscriber with a second communication end device (B). Connections (10, 11, 2a, 2c) are further established to a backbone (1) through a local gateway (3a) and a destination gateway (3c), wherein said gateways provide for an economical communication. The local gateway (3a) and the destination gateway (3c) are determined so that the current charging rate towards the communication end devce (A) of the calling subscriber, or towards the communication end device (B) of the a called subscriber, is as reduced as possible.

Abstract: For each connection in a mobile radio network, at least one quality parameter is determined. A server (6) in a mobile radio network (7) calculates at least one statistical quality indicator (pi.) from quality parameters of multiple connections of a user, as well as at least one quality criterion (G, Gi), which depends on a plurality of connections with different mobile devices (1). Based on the determined quality indicators, the server (6) decides which mobile devices (1) do not fulfil the quality criteria (G, Gi) and must be rated as critical. The user of a mobile device, which does not fulfil one or more established quality criteria, is informed by means of an indication in his telephone bill. The quality parameters are determined in the base stations (2) of the mobile radio network (7) and collected in said server (6). The method may also be applied to the determination of the quality of components of the infrastructure, for example base stations (2).

Abstract: A communication system, in particular a mobile communication system that can to be carried by a user without using hands, which includes a control unit as well as one or more signal receiving modules and signal emitting modules that each have a radio device interface. The control unit includes a registration device to automatically register, or respectively deregister, modules dynamically added to, or respectively removed from, the communication system by the user. Data can be received in the control unit from the modules by the radio device interface, or respectively transmitted selectively to the modules by the radio device interface, it being possible to configure from which signal receiving modules data is supposed to be conducted to which signal emitting modules.

Abstract: In a method for authenticating persons, video information of certain body features associated with a user or a user group is recorded in a point of presence (POP). Such recorded video information is processed to derive biometric keys, which are stored in tables of a biometric server and in a SIM-card of the user. Each biometric key in the tables is assigned to a respective user. When the user inserts the SIM-card containing a personal biometric key into a communication terminal device, video information describing current body feature of the user is recorded via a video sensor that is not in the communication terminal device. The recorded current video information is then transmitted from the video sensor to the communication terminal device. To authenticate the user, the recorded current video information is processed to derive current biometric keys and compared with pre-stored biometric keys. The authenticity of the user is ensured if the comparison yield a positive result.

Abstract: The oscillator integrated into a chip can generate an electrical clock signal with a reference signal, wherein the chip contains the following components: at least one laser transmitter, which can generate two coherent light signals with a differing optical transmission frequency, a coupler, in order to merge the two light signals, an electromagnetic converter, which can generate an electrical signal, whose frequency corresponds to the distance between the two transmission frequencies, a frequency divider, which can divide the frequency of the electrical signal in order to deliver a clock signal with a lower frequency. The oscillator can be inserted into a SIM card, for example, in order to make possible a non-falsifiable determination of the connection duration.

Abstract: A method and apparatus for billing connections of a subscriber identified by a SIM card in a telecommunications network to the subscriber user, including determining the duration and time of the connection using a time-measuring device integrated into the SIM card, which is synchronized with an external clock signal, and determining the amount to be charged based upon connection duration and time and at least one remotely loadable tariff table stored in the SIM card. The time-measuring device can be checked by a time server in the infrastructure, and, if necessary, can be adjusted. The method and apparatus can be used for prepaid as well as for post-paid cards. All data for determining the amount to be charged are available on the SIM card, allowing billing to take place at the source, at the user. No other billing system is required in the infrastructure.

Abstract: A method for loading or reloading a SIM card (7) for a mobile device (6). The SIM card (7) has an electronic chip with a storage device (11). In the storage device (11) a monetary sum (28) is stored, and decreases as the mobile telephone is used. For loading or reloading the monetary sum, a prepayable value card (13) is purchased. The value card (13) has a code field (14) covered by a removable opaque layer (22). Upon removal of the layer (22), a code (15) becomes visible. The holder of the SIM card and the value card calls a service number using a communication apparatus (6, 8). The caller is thereby connected to a data base (17) in which all codes assigned to value cards (13) and the sum of money associated with each code are stored. The caller is prompted to enter the code (15) on the calling communication apparatus. The code (15) entered is compared with the codes stored in the data base (6, 8).

Abstract: Billing method for billing a call by a subscriber identified with a SIM card (10) in a telecommunications system (2) to said subscriber, comprising: Determination of the duration of the call by means of a time-measuring device (100) integrated into the SIM card (10); Evaluation of the amount to be billed based upon the determined call duration and at least one tariff table stored in the SIM card (10). The tariff tables are stored in a tariff server (6), and can be remotely loaded into the SIM card (10) through said telecommunications network (2). Advantages: since all data for determining the invoiced amount are available on the SIM card, the billing takes place at the user directly at the source. No other billing system is required in the infrastructure.

Abstract: The system for transmitting messages is used in a mobile radio telephone network (1) having a number of terminals (4, 9). The terminals may be either permanently allocated to a specific user or allocated to a specific user by means of a chip card insertable in the terminal. At least two terminals can enter into voice or data communication with one another in the mobile radio telephone network. The mobile radio telephone network comprises at least one center (8) for controlling the message transmission, each message being a data communication in which data telegrams containing a standardized data header are exchanged. For processing special services according to a special procedure accessible only to a certain authorized subscribers, the data telegram comprises an identification code in addition to the standardized data header. A central unit (10) associated with the center and at least some of the terminals have units for generating data telegrams provided with the identification code.
