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).

The message diffused by the platform, can be listened to from a plurality of terminals. The messages are transmitted through the telecommunications network in coded form, the code including a semantic representation of messages, and then are converted into audio signals at a network access point of the packet switching telecommunications network. The network access points are distributed geographically and can generally be accessed by a local tariff call.

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: 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: An access control system comprises a plurality of access control devices in each of which is stored an access code. Specific access codes and access rights for a plurality of access control devices are transmitted from an access control central unit over a mobile radio network to the mobile communication terminal of a user. Transmitted to the mobile communication terminal by an access control device to be passed is an access control device identification. In the mobile communication terminal, on the basis of the received identification, the access code and the access rights for the access control device to be passed are determined, and are transmitted to the access control device. The access control device clears the user for access if the received access rights suffice and the received access code agrees with the stored access code.

Abstract: In a wireless local communication network, a so-called Wireless Local Area Network (WLAN) a prepaid value code is transmitted from a wireless communication terminal via an air interface to an access point unit of the wireless local communication network, a so-called access point. The validity of the received value code is checked in a value code database by a centralized access control server. If applicable, the access to the wireless local communication network and to communication networks connected thereto, for example the Internet, is cleared for the wireless communication terminal. After the clearance, a monetary amount is credited to the operator of the access point unit and the validated value code is cancelled in the value code database.

The microphone is connected to the voice analysis module and thus also enables a human operator within earshot of the mobile robot to control the displacements of the mobile robot through voice commands.

Abstract: A method to enable a user of a system to obtain access to one or more services, for example, to enable a caller to access some information on a remote server. The system first prompts the caller to identify himself by entering a subscriber code. A speaker verification is then made using a voice comparison between the caller's voice and a voice reference associated with the subscriber the caller claims to be. Access to the requested services is given if the outcome of said voice comparison is positive. If the system does not store a sufficiently good voice reference to verify the identity of the subscriber the user claims to be with a predetermined degree of reliability, the caller is prompted to enter a confidential PIN code. If the PIN code entered is correct, access to the requested services is given and a new voice reference is stored.

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.
