Abstract: The invention relates to an authorization verification method and devices suited therefor, which play back authorization data via a user interface (11) of an electronic playback device (1). During the playback of authorization data via the user interface (11) of a first playback device (1), the playback attributes are modified. The playback of authorization data via the user interface (11) of the first playback device (1) is compared with the playback of reference data via a user interface (21) of a second electronic playback device (2). Authorization is granted in the event the playback of authorization data via the user interface (11) of the first playback device (1) matches the playback of reference data via the user interface (21) of the second playback device (2), and modifications of the playback attributes are, in essence, time-synchronized.

Abstract: A computer system determines location probabilities for defined sub-areas (41, 43) of a geographical area (4), e.g. for squares arranged in a grid (40), based on field strengths expected in the small sub-areas (41, 43) from the antennas (A1, A2 A3, A4), and based on the antenna used by the mobile communication terminal. The location probabilities indicate for a sub-area (41, 43) the probability that the mobile communication terminal is located in the respective sub-area (41, 43). The computer system determines at least one ellipse defining the location area, based on the location probabilities of the sub-areas (41, 43). The location probabilities make it possible to determine elliptical location areas of mobile users much smaller than the area each antenna does cover physically, but without the need for measuring at the mobile communication terminal signal properties such as signal strength or observed time differences.

Abstract: A computer system determines and stores antenna probabilities for defined sub-areas (41, 43) of a geographical area (4), e.g. for squares arranged in a grid (40), based on field strengths expected in the small sub-areas (41, 43) from the antennas (A1, A2 A3, A4). The antenna probabilities indicate for the antennas (A1, A2 A3, A4) of a mobile radio network the probability that a mobile communication terminal uses a respective antenna (A1, A2 A3, A4) when located in a particular sub-area (41, 43). The computer system determines the current location of the mobile communication terminal based on the antenna probabilities associated with the antenna used by the mobile communication terminal.

Abstract: Order requests for playing audio contents and/or video contents are transmitted by way of communication transmission apparatus (3) via a telecommunication network (2) to a computer-based central unit (1). The central unit (1) determines one of several geographically distributed play units (5, 6, 7) which are remote from the central unit (1) and are separate from the communication transmission apparatus (3), on account of details which are transmitted with the order requests, e.g. an identification or a location detail of a play unit (5, 6, 7), or a location detail of a mobile communication transmission unit (3), for playing the audio contents and/or video contents. The audio contents and/or video contents are transmitted from the central unit (1) as a continuous data flow to the selected play unit (5, 6, 7), and are played there via loudspeakers (51, 61, 71) or displays (52, 72).

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 computer-based system for dynamic assignment of carrier frequencies to computerized access points of a wireless local area network (WLA) is connected to the access points via a communication connection. Present operational values, such as the present number of associated users and the present number of received faulty and errorless data packets, are captured from the access points via the communication connection by autonomous agent modules of the computer-based system. In the computer-based system, individual weighting factors for the access points are calculated, based on the captured operational values. Access point data about the access points, which include present carrier frequencies and weighting factors, are stored in the computer-based system.

Abstract: Method of management in a circuit-switched communication network (1), performed on or with the aid of at least a programmable apparatus (10) connected to said network. It comprises the step of computing and storing in an electronic memory a representation of the network based on B-blocking islands (Ni). Each B-blocking island consists of a set of nodes (A-g) linked in such a way that at least one route with at least an amount B of available concave resources exists between any pair of nodes in the set at the time t. The B-blocking islands (Ni) are organized in a hierarchy, wherein the hierarchical position of each Bi-blocking island depends on the choice of the values Bi used for defining said blocking island. The available bandwidth resources are thus summarized in order to reduce the complexity of network management tasks. Bottlenecks in the network are highlighted. The B-blocking-island hierarchy can be incrementally maintained.

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 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.
