Abstract: Telecommunication method which enables a subscriber of a home mobile radio network (HPLMN) to connect to a visited mobile radio network (VPLMN, VPLMN′) without a roaming agreement with the home mobile radio network (HPLMN) in that the subscriber is assigned a first mobile subscriber identification (IMSI1) from the number range of his home mobile radio network (HPLMN) and a second IMSI number (IMSI2) from the number range of a partner network (PPLMN), the partner network having additional roaming agreements, and a common call number (MSISDN) being allocated to the two said IMSI numbers (IMSI1, IMSI2). The two IMSI numbers (IMSI1, IMSI2) may preferably be stored on a common or on different identification modules.

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 system of voice information diffusion through a packet-switching telecommunications network starting from a platform for an automatic voice teleservice system. 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: A method for on-line monitoring and testing the behavior of middleware based, distributed application software during run-time of such software is disclosed. In order to automatize the monitoring of the behavior of the application software, the monitoring method comprises: defining events capturing the behavior of the software execution, the events being based on an abstraction of the application software, the abstraction being provided by middleware; using code generating means and an instrumentation technique for automatically adding code to the implementation of the software code suitable for generating traces suitable to be sent to an observer, the information carried by the added code including information on the order of occurrence of the events and on the application software part location where each event occurs; and using a monitoring mechanism based on sending of trace reports to the observer, which ensures or takes into account the time order of the reported traces.

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: 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.

Abstract: Method for random-access communication in communication networks (1) with time-slotted transmission channels which are being accessed by a plurality of terminal devices (2), whereby the terminal devices (2) are provided with binary feedback (S/{overscore (S)}) by a common receiver (3), a positive feedback (S) indicating that a particular slot contained a successfully transmitted packet or a negative feedback ({overscore (S)}) indicating that the particular slot did not contain a successfully transmitted packet, and whereby dummy packets are transmitted by an auxiliary user (4) following the first negative feedback ({overscore (S)}) after a prior collision has been resolved to determine whether said negative ({overscore (S)}) feedback was due to a collision of packets in the respective slot or whether it was due to this slot having been empty.

Abstract: A system and method for communicating a key between two stations using an interferometric system for quantum cryptography. The method includes sending at least two light pulses over a quantum channel and detecting the interference created by the light pulses. The interfering pulses traverse the same arms of an interferometer but in a different sequence such that the pulses are delayed when traversing a quantum channel. The pulses are reflected by Faraday mirrors at the ends of the quantum channel so as to cancel any polarization effects. Because the interfering pulses traverse the same arms of an interferometer, there is no need to align or balance between multiple arms of an interferometer.

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: A subscriber identification SIM card for a mobile telephone comprises an advice of charge counter ACM indicating the amount corresponding to the communications carried out with the card. An EEPROM memory in the card includes a file ACMmax, indicating the maximum value of the advice of charge counter, and at least one file EFFDN indicating at least one telephone number free of charge. The invention compares the amount indicated by the advice of charge counter with the maximum amount of the advice of charge counter and blocks calls according to the result supplied. However, the invention does not block calls intended for one or more predetermined numbers stored on the card. It is thus possible to call, for example, an emergency number or the number of a server to reload the card, in the case of a prepayment card, even after the credit on the card has been used up.
