Abstract: The present application relates to a system hosting a monotonic counter and a method of operating the system. The system comprises a non-volatile memory (110) for holding a save counter value and a volatile memory (120) for maintaining a current counter value. The system (100) is configured during a startup phase to retrieve the saved counter value of the monotonic counter from the non-volatile memory (110); to detect whether a previous shutdown of the system (100) was an uncontrolled shutdown; and to adjust the retrieved counter value in accordance with a step size (130) provided at the system (100) in case an previous uncontrolled shutdown is detected.

Abstract: Due to emerging cellular standards, such as UMTS, TDMA and WLAN, there is more and more need for so-called multi-mode mobile phones, i.e. phones which support not only one air interface but at least two. According to an exemplary embodiment of the present invention, a simplified synchronization of a plurality of time base units in a receiving station, such as a multi-mode mobile phone, is provided, in which the plurality of time base units is synchronized by performing a calibration of one first time base unit only and then using the calibration for synchronizing the other time base units with the calibrated first time base unit. Since the synchronization of the various time base units can be performed by software, the number of hardware components for synchronization may be significantly reduced.

Abstract: A method of correcting a real-time clock of an electronic apparatus, notably a mobile telephone, in which the real-time clock operates with a first clock generator which generates a real-time clock while the electronic apparatus operates with a second clock generator which generates a system clock, which method includes the following steps: determining the actual frequency of the real-time clock, determining the ratio Vclock/standard of the actual frequency of the real-time clock to the reference frequency of a standard clock, determining the deviation time of the real-time clock per second from the difference (1?Vclock/standard), determining, on the basis of the deviation time per second, a time difference dt within which the real-time clock is to be corrected by a correction time difference ?t, correcting the real time by ?t after expiration of dt.

Abstract: To be able to use a clock generation unit (2) for different mobile radio systems, the clock generation unit (2) which includes a phase-locked loop (4) for converting a reference clock (fR) into a working clock is provided and includes circuit portions (16a, 16b; 20a, 20b) which are designed for different reference clocks (fR) while a respective one of the circuit portions (16a, 20a) to which a special reference clock (fR) is assigned can be selected. The clock generation unit (2) can thus be operated with different reference clocks of different mobile radio systems.

Abstract: The invention discloses a mobile radio telephone set including at least one control processor and at least one signal processor which are at least occasionally not in an active mode. To reduce the energy consumption of the mobile radio telephone set in the simplest manner possible, a control unit selects operating modes at least for the control processor and/or the signal processor. By utilizing a separate control unit, more particularly two or more coupled processors or other switching units of the whole mobile radio telephone set may be controlled independently. Each coupled unit may at once individually be set to its own operating mode to operate only the currently necessary units in this manner and reduce the energy consumption in this manner.

Abstract: A mobile radio telephone set includes modules which are connectable by control signals. The modules include a control signal generator and a digital signal processor with a memory. The control signal generator is connected to the memory which stores at least one data word for a corresponding control signal. For rapidly and flexibly changing the control signals, the memory supplies data words which contain two control signals for at least two control lines coupled to the control signal generator. Each data word supplied by the memory contains at least two control signals in coded form. Each time a data word is supplied by the memory, at least two new control signals can be conveyed to the control lines. As a result, a selectable number of control signals may be changed simultaneously and flexibly because random data words can be stored in the memory.
