Abstract: A filter sector assembly for a disc filter, which disc filter has a fiber suspension containing bath and a core assembly adapted to rotate on a horizontal axis. The filter sector assemblies are rotatably supported with relation to the bath on the core assembly. The filter sector assemblies are spaced along the core assembly and supported on the core assembly. Each filter sector assembly (50) has two adjacent filter sectors (10A; 10B) releasably fixed to a bent support plate (30). The two adjacent filter sectors (10A; 10B) are attached as a pair of filter sectors (10A; 10B) by fastening the support plate (30) to the core assembly (21; 21A, 21B) of the disc filter.

Abstract: A forming section has a lower wire loop (11), which constitutes a single-wire section (T) following a breast roll (12). A first dewatering zone (Z1) has at least one stationary, first forming shoe (40) followed by a pulsating strip cover (50). The first forming shoe has leading and trailing edges and underpressure affecting through holes of the cover. The holes are openings or slots substantially in the longitudinal direction of the machine, whereby non-pulsating dewatering is applied on the stock travelling on top of the lower wire. A pulp suspension jet is fed from a headbox (30) at an impact point after the shoe leading edge. The cover is straight at least in the area between the impact point of the pulp suspension jet and the trailing edge. The impact of the pulp suspension jet on the forming wire is thus better controlled in a better way, increasing production speed.

Abstract: There is disclosed a technique for estimating a power change, particularly a power increase, in a communication system caused by a change in the load in the system. The technique particularly relates to a mobile communication system.

Abstract: In connection with the determination the transmit power of a beginning transmission there is also determined, in the method according to the invention, suitable output powers for other transmissions, so that the entity formed by all controlled transmissions is as close to the optimum as possible already at the beginning of a new frame. The method according to the invention takes into consideration the effect of a beginning transmission on other transmissions. The method according to the invention further takes into consideration changes in the conditions during the previous frame by including the control history of the fast power control as initial information of the calculation made during the re-determination of the output powers, for instance as a suitable statistical quantity of the transmission history of each transmission, for instance as an average over a certain period.

Abstract: The present invention relates to a method in a communication system. The system comprises a controller arranged to control transmission power of stations, a first station and a second station, the controller being arranged to provide the first station with a target for use in control of the transmission power of the second station, monitoring means, and means for preventing use of a target for the transmission parameter that exceeds a limit value. The controller provides the first station with the target and the first station adjusts the transmission power of the second station on basis of the target. A predefined condition is monitored, and upon occurrence of the predefined condition, use of a target for the transmission parameter exceeding a limit value for the target for the transmission parameter is prevented.

Abstract: The invention is related to control of transmissions in spread spectrum radio systems, more accurately to estimating transmission power increases caused by new transactions in the system. According to the invention, the estimate or interference power increase due to a new transaction is calculated at least partly on the basis of the current fractional load, the current received interference power level, and a load factor ?L, which is calculated essentially on the basis of the chiprate, the bitrate of the new transaction, and the estimated required signal-to-interference ratio for the service type of the new transaction.

Abstract: The present invention relates to a method and network element for controling power and/or load in a network, wherein a reference table is stored and used for deriving a reference control value from at least one connection-specific parameter. The power and/or load control is then performed based on the derived reference control value. The reference control values stored in the reference table are estimated based on a real measurement of at least one predetermined network parameter, and the reference table is updated using the estimated reference control values. Thereby, an autotuning mechanism is provided to adjust the reference control values based on real measurements, so that real location-dependent radio propagation conditions are taken into account.

Abstract: The present invention proposes a method for traffic load control in a telecommunication network consisting of at least one radio terminal (MS) and at least one radio transceiver device (BS), each radio transceiver device (BS) defining a cell of said network being controlled by a network control device (RNC); comprising the steps of: setting a first reference load value for the load of a respective cell; monitoring the load of said respective cell, and in response to the load exceeding the first reference load value, manipulating the power control to decrease the transmission power levels in the cell. The present invention thus proposes a fast load control method in that during a situation in which a certain reference load value is exceeded, the load is controlled per base station sector by affecting, e.g. transmit power commands. In addition, such load reductions can be supplemented by re-negotiating bit rates, for example.

Abstract: A data transmission system comprises a first device and a second device and a duplex data transmission connection therebetween. The first device sends to the second device user data on a data channel and control information on a control channel. The transmission is arranged in frames that comprise a user data field corresponding to a data channel and at least a first and a second control information field corresponding together to a control channel. In order to realise the control of the transmission power, there is determined a first transmission power level, a second transmission power level and a third transmission power level. From the second device to the first device there is transmitted a frame by applying said first transmission power level to the transmission of the user data field, said second transmission power level to the transmission of the first control information field and said third transmission power level to the transmission of the second control information field.

Abstract: The discussion concerns the mutual arrangement of packets to be transmitted in a radio system, where the transmitted data is formed into packets (204, 205, 206) for the transmission. The system comprises at least two transmitting devices which transmit substantially simultaneously and substantially on the same frequency, whereby the carrier power transmitted by the first transmitting device is interference power to those receiving devices, to which the second device transmits carrier power, and vice versa. In order to arrange the packets there is generated a utility function with a value, which depends on the carrier power and the interference power and which can be obtained by calculation for the transmitted packets in their mutual transmitting order at that moment. The packets to be transmitted are arranged in a mutual transmission order corresponding to the extreme value of the utility function.
