  • Patent number: 6792248
    Abstract: A method for controlling transmission power in a radio system and in a WCDMA system network in particular for maximizing cell capacity. An acceptable transmission power margin and an optimum power level, which may change specifically for each connection and service class, are determined for the transmission power. Transmission power is adjusted using power control steps utilizing an incoming power control command and previous power control steps. The power control step size is adjusted as a sum of a fixed and a variable dynamic step size where the dynamic value is obtained on the basis of the measured value and the target value of the signal-to-noise ratio. Information on the network state can be obtained by comparing AC and LC data and the cell capacity can be maximized by controlling the amount of transmission power calculated by the mobile station before the final power transmission.

  • Patent number: 6792249
    Abstract: When using a magnetic alternating field to prompt portable electronic tickets, such as smart cards, it is important that the prompting is effected reliably and independent of the position thereof. In order to generate an essentially isotropic magnetic alternating field over a set time interval, one embodiment of the invention involves the use of an antenna array comprising two or three frame antennas. A switching unit supplies, in a sequentially alternating manner, a unit of information to each of the frame antennas so that a quasi-isotropic magnetic alternating field, which is considered over the period of time, is radiated by said frame antennas. This results in reliably prompting tickets that are located in the surrounding area of the antenna arrays.

  • Patent number: 6792252
    Abstract: An error amplifier circuit reduces distortion in an amplified signal by reflecting a feedback signal into the amplified signal using an output transformer. A first amplifier generates a reference signal corresponding to the input signal from which the amplifier output signal is derived. This reference signal represents the desired waveform for the amplified signal. An error sense element generates an error signal based on the difference between the reference and amplified signals. The error sense element preferably imparts high common-mode rejection to the error signal. A second amplifier generates the feedback signal based on amplifying the error signal, and an output transformer generates a compensated amplified signal by coupling the feedback signal into the amplified signal. The output transformer increases the reflected load impedance seen by the error amplifier, thus relieving it from driving the feedback signal into the potentially low load impedance driven by the compensated amplified signal.

  • Patent number: 6792253
    Abstract: Electric fields A, B and C are inputted to an antenna 20, and corresponding digital values AAD, BAD and CAD obtained from an A/D converter are stored in memories A6, B7 and D12, respectively. An operational circuit 9 obtains a non-linearity corrected input power level conversion table from the input power levels of the electric fields A, B and C and the corresponding digital values AAD, BAD and CAD, and stores the obtained table in a memory C8. The electric field C is the electric field under which the receiver circuit is not linearly operated. A controller reads out the input power level at the time of input of each electric field from the memory C8, and displays the read-out input power level on a input power level display 10. Thus, adverse effects, on linearity, of saturation caused by high input power level electric field input to an antenna or of noise at the time of low input power level electric field input are improved.

  • Patent number: 6792268
    Abstract: Spectrum monitoring measurements are made by microcell base stations in a layered cellular network, while not serving calls or engaged in processing calls. The microcell base station transmits a first control message from to a microcell mobile station, to increase the duration for the mobile station to reside in the camping state on a control channel of the microcell base station. The microcell base station transmits a second control message from the microcell base station to the microcell mobile station, to increase the duration for the mobile station to reside in a call origination state while attempting to access a control channel of the microcell base station. Then, to perform the spectrum monitoring measurement, the base station's transmitter is turned off, the receiver is retuned to the frequency to be monitored, a signal strength measurement taken on that frequency, the receiver is retuned back to its assigned frequency, and the transmitter is turned back on, all in a short time interval.

  • Patent number: 6792270
    Abstract: The invention relates to a device for a GSM (Global System for Mobile Communication) communication system offering a GPRS (General Packet Radio Service), for determining the base station subsystems involved in a paging on a routing area level. Moreover, the invention relates to a method for setting up and/or updating the device. The set-up and/or the update of the device takes place in a GPRS service node, for example, after the receipt of a message on a set-up, a release or a modification of virtual connections. For this purpose the information contained in the message are evaluated and compared with already existing information. Another possibility is the evaluation of information in data packets, which, too, are compared with already existing information. Subsequently the information is, if required, updated and stored.

  • Patent number: 6792271
    Abstract: A method and system are provided for registering and operating a wireless telephone in a roaming service area in which the wireless telephone is not registered for roaming services. When a wireless telephone is operated in a such a roaming service area, the roaming service provider whose services the wireless telephone must utilize in order to operate in the roaming service area informs the user of the wireless telephone through a recorded or live message that the wireless telephone may be used in the roaming service area if the user of the wireless telephone purchases and uses a prepaid utilization account offered by the roaming service provider. If the user purchases a prepaid card and loads a balance into a prepaid utilization account, a prepaid services system of the roaming service provider establishes a pseudo-telephone number for use by the wireless telephone in the roaming service area.

  • Patent number: 6792273
    Abstract: Resources are reserved or otherwise allocated in a mobile radio communications system in an efficient and timely fashion. In general, the amount of resources that will likely be necessary to support a connection with a mobile station is predicted before those resources are actually required. More specifically, an unknown value of a dynamic connection parameter, like a number of radio paths likely to be involved in supporting the connection, is predicted. In the handover context, these radio paths might correspond to paths with different base stations (as in hard and soft handover) or to paths with different base station sectors (as in softer handover). The underlying resources are allocated using the predicted connection parameter and may include, for example, data processing and memory hardware resources, software resources, radio resources, etc.

  • Patent number: 6792274
    Abstract: In a system handling communication between base transceiver stations (BTS1-BTS12) and base station controllers (BSC) of a cellular radio network the transmission capacity is composed of a predetermined number of capacity units (T0-T31). At least one capacity unit (TCH) can be allocated to a given base station group which comprises at least two base transceiver stations. Said capacity unit is allocated to a certain base transceiver station in the base station group when the instantaneous volume of traffic handled by said base transceiver station requires temporary allocation of additional capacity, and said capacity unit is again released so as to be allocatable to the base station group when the instantaneous volume of traffic handled by said base transceiver station no longer requires temporary allocation of additional capacity.
