Abstract: A method for minimizing energy usage in a portable unit in a wireless communications system incorporates means to locally generate information on motion of the portable unit and to adapt a transmission from the portable unit based upon such motion information so that energy usage is minimized. By applying this method, information concerning motion of the portable unit is utilized in order to adapt transmissions from the portable unit in such a way that less energy is consumed. In the case of a portable telephone, connection time is thereby primarily increased, because it is then that most energy is used for transmission. In many cases standby time is also increased because many telephones also transmit information during standby, for example during so-called roaming.

Abstract: In a data transmission system, the QOS (quality of service) is continuously monitored (15) by measuring certain system parameters. If too low a QOS is found (16), individual or a number of further tests (19, 20, 21) are automatically and immediately started in order to determine the information about the system state which is required for locating the cause of the low QOS. Apart from the measurement of particular system parameters, these tests also comprise the collecting of certain quantities already present in the system. A test can also start other additional tests (22, 23), the individual tests being configured in dependence on the system parameters already known, in such a manner that they provide meaningful results for the current conditions.

Abstract: In a method of testing a cellular network system in which setting up a communication link between two subscribers starts with a negotiation phase comprising the two steps of one of the subscribers sending a request (21) for a connection with the other subscriber to a network management and of the network management sending back an answer (23) to the subscriber, wherein the link can be established if the network management's answer (23) satisfies certain conditions, for testing the cellular network system the subscriber's request (21) and the network management's answer (23) are monitored and analyzed. Preferably, the set up process is actively terminated after the negotiation phase, before an actual link is established. Thereby, it is ensured that the use of network capacity is minimized for test links.

Abstract: To determine the transmission efficiency of a data communication network in order to raise the data throughput, the transmission-time, that means the time actually used for user data transmission, is determined. By building the ratio of the transmission-time and the duration of the respective user data transfer session the network operator can measure the transmission efficiency. Depending on the transmission efficiency he then can improve the data throughput by either raising the transmission efficiency or by adding more transmission capacity.

Abstract: The invention relates to a method for evaluating the quality of a signal transmission path (2) presenting non-linear distortions. According to said method a specified test signal is sent from a transmitter (1) to a receiver (3). First the level of the received signal is adjusted in the receiver (3) and then a global quality evaluation is carried out using a specified comparative method. To adjust the signal level a local quality evaluation (11) based on the specified comparative method is carried out in a specified number of different, predefined windows (V1, à, VN?1, VN). Thereafter at least one window with an adequate local transmission quality is determined. The ratio of signal level of the test signal to signal level of the received signal is calculated in at least one window and the level of the entire received signal is adjusted on the basis of this ratio. Preferably only windows containing, for example, at least 50% of the total signal energy are used for adjusting the level.

Abstract: In a postage meter system (FIG. 2), a user enters information,indicative of a batch of mail pieces to be franked (30). The mail pieces are franked(31), and when the batch is completed, data relating to the batch are made the subject of a cryptographic engine(33). The data digitally signed, or a message authentication code (MAC) is derived, all in a postal security device (PSD)(32). The data are communicated(34), preferably by means of public-key cryptography(35). These data are then made available to the postal authority in a secure way.

Abstract: In an arrangement for accounting for consumption of a resource, e.g., utilization of a postal service or utilities, a data center (503, 803) periodically communicates with multiple franking systems (100, 505-1, 505-2, 505-n) dispensing postage for the postal service utilization. The data center (503, 803) receives transaction records (301, 303, 305, 307, 309), where a transaction record (301, 303, 305, 307, 309) is associated with each transaction performed by the franking system (100, 505-1, 505-2, 505-n) in each period. Each record (301, 303, 305, 307, 309) includes at least the postage dispensed (305) in the associated franking transaction, and an ascending register value (307) indicating the cumulative postage dispensed. Using the received records (301, 303, 305, 307, 309), the data center (503, 803) assesses the charges during the period and causes assessed charges to be charged to an account associated with the franking system (100, 505-1, 505-2, 505-n).

Abstract: A franking machine control panel and its associated method provide users with touch screen displays in which the main screens contain history tabs. When a history tab is pressed, the display reverts to the previous status of the category of interest, and allows the user to make changes if desired. In the preferred embodiment, the history tabs allow users to view and modify information which is mandatory to the franking process, such as the mail class and postage rates. Another aspect of the present invention allows the user to configure the more actively used buttons of touch screen on one side or the other, depending on the dominant side of the user's body.

Abstract: An improved system is provided for authentication of mail pieces bearing bar-coded indicia. The system comprises first and second bar-code readers, the first and second bar-code readers differing in that the first bar-code reader has a lower rate of successful reading of bar-coded indicia than the second bar-code reader. The system collates a mail piece bearing an indicium in a second paper path in the event of a successful reading of the bar-coded indicium by said first bar-code reader, and collates mail pieces in a third paper path in the event of an unsuccessful reading of the bar-coded indicium by the first bar-code reader. The third paper path leads to the second bar-code reader, and the system collates mail pieces in a fourth paper path in the event of a successful reading of the bar-coded indicium by the second bar-code reader. The system collates mail pieces in a fifth paper path in the event of an unsuccessful reading of the bar-coded indicium by the second bar-code reader.

Abstract: In accordance with the invention, a postal security device (PSD) (10) contains a non-volatile memory (13) which does not depend on battery power such as an EEPROM (13), and contains a nonvolatile memory (14, 16) which does depend on battery power, such as a static RAM. The PSD (10) also contains an encryption engine (12, 14, 22). An encryption key is developed and is stored in the static RAM (14), which is sized to be only large enough to contain the encryption key. A large body of data, too large to fit in the static RAM, is encrypted by means of the encryption engine (12, 14, 22) and with reference to the encryption key, and is stored in the EEPROM (13). This body of data typically includes cryptographic keys and sensitive bit-images. When the PSD is powered, a large RAM (typically a dynamic RAM) (16) is available to receive the large body of data, decrypted using the encryption key. A tamper switch (17) cuts power to both RAMs (14, 16) in the event of tampering.

Cryptographic processing occurs in the PSD, which provides security to these resources, thereby minimizing a successful fraudulent attack on the system. Speed of the cryptographic processing is also increased. The PSD may be in the form of an Applications Specific Integrated Circuit (ASIC) or Personal Computer Memory Card International Association (PCMCIA) Card.

Abstract: A coupling apparatus (1) having a mains connection (2) for connection to a low-voltage mains power supply system, and having an appliance connection (3) for connection of any appliance for transmitting and/or receiving an RF signal has a voltage converter (5) and a high-pass filter (6.1, 6.2). The voltage converter converts the mains voltage which is present at the mains connection to a very-low voltage, which is suitable for supplying the appliance connected to the appliance connection. Inductances (4.3 to 4.6) of suitable size are interposed in the appropriate connecting lines as low-pass filters for decoupling the RF signal path from the supply signal path, and for suppressing undesirable, radio-frequency signal components in the supply voltages. RF signals which are transmitted or are to be transmitted via the low-voltage mains power supply system are coupled from the mains connection via the high-pass filter to the appliance connection, and from the appliance connection to the mains connection.

Abstract: The invention relates to a method for the automated analysis and appraisal of a mobile radio telephone system (1). Said method scans calls that are executed as part of a test phase, in accordance with internal and external system parameter values which flag error conditions (e.g. handover errors) or system performance deficiencies (e.g. poor voice quality during transmission). In a subsequent step, the parameters are evaluated in several modules (12.1–12.3) according to selectable grouping criteria, whereby for each module a multitude of relevant events or event sequences are examined and a module quality value (17.1–17.3) is determined with regard to a specific appraisal criterion. The system quality value (20) of the entire system is calculated as a weighted sum of the quality values from the individual modules and can be displayed graphically as a comparison of all groups, with regard to the chosen grouping criterion.

Abstract: In a radio communication system, where a user (8, 9), who wants to transmit data, is allocated a certain transmission capacity. It is a general goal to have an efficient resource allocation algorithm. In order to serve as much subscribers of the network as possible, the allocation of the available resources is improved by determining an utilization factor, which is some kind of measure for the exploitation of the transmission capacity allocated to a user. This is done by analysing the communication activities of the user (8) by monitoring for example directly the radio link (10) between the users terminal (8) and the corresponding basestation (4) with a monitoring device (16.4). The monitoring of the communication can also be done in other locations (16.1, 16.2, 16.3, 16.5), e.g.
