  • Patent number: 7738412
    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.
    Type: Grant
    Filed: November 23, 2001
    Date of Patent: June 15, 2010
    Assignee: Nokia Corporation
    Inventors: Ari Hamalainen, Janne Laakso, Kimmo Valkealahti
  • Patent number: 7532892
    Abstract: The present invention relates to a method and a cellular radio network device (3) for controlling the admission of user (4, 6) to a cellular radio network (1). In order to determine how much traffic is allowed in a cell (2), threshold values are autotuned using quality measurements gathered during high load on a link. Thus, the network capacity is in increased while fulfilling desired quality requirements.

  • Patent number: 6985700
    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.

  • Publication number: 20050107106
    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.

  • Patent number: 6778839
    Abstract: A method and device for selecting transmission power and bit rate in a wireless telecommunications network, especially in the context of open loop power control, is disclosed. Transmission power and bit rate are selected in response to input parameters so as to minimize a cost function representing induced interference and transport delay.
