Abstract: A method for teaching an anomaly detecting mechanism in a system comprising observable elements (302), at least one of which has a periodic time-dependent behaviour, the anomaly detecting mechanism comprising a computerized learning mechanism (314). The method comprises assembling indicators (304) indicating the behaviour of the elements (302) and arranging the assembled indicators such that each observable element's indicators are assigned to the same input data component. The learning mechanism (314) is taught so that the input data of the learning mechanism comprises the input data components which are based on the assembled indicators (304). Points which approximate the input data are placed in the input space. A presentation of time (420-424) is incorporated into at least one input data component wherein the presentation of time is periodic, continuous and un-ambiguous within the period of the at least one element with periodic time-dependent behaviour.

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.

Abstract: A method and system for monitoring the behavior of at least one observable object, e.g. a network element, of a network, wherein at least one parameter of the observable object is repeatedly detected. An actually detected parameter is input to a learning process and to an analyzing process, wherein the learning process forms a reference, based on at least two detected parameter values, for describing the behavior of the observable object. The analyzing process compares the input parameter and the reference for detecting an anomal behavior. The parameter preferably is a vector which includes several values describing properties or functioning of the observable object, and is formed based on events and/or reports from the object.

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: When optimising the performance of the network, first of all, the relevant key performance indicators for a specific entity within the network as well as first parameters, which influence the key performance indicators, are determined. A number of entities similar to said specific entity is selected, wherein relevant key performance indicators are associated to every entity. The key performance indicators as well as the selected number of entities are used as elements in a first cost function, i.e. said first cost function is calculated on the basis of the KPI and the number of entities. Said first cost function is calculated in order to evaluate the network performance. Accordingly, since said first parameters directly relate to the key performance indicators, the network performance will depend on the values of said first parameters.

Abstract: This invention concerns a method for controlling at least one radio bearer parameter of a first radio bearer (RB), and a Radio Bearer Control unit. The invention introduces a continuous monitoring and controlling of the RAB-RB parameter mapping for new and for already active connections. According to the invention a method for controlling at least one radio bearer parameter of a first radio bearer (RB) to be established or maintained between a mobile terminal and a first access-network node in a first cell of a cellular radio access network is provided. The first access-network node communicates with a core-network node in a core network to establish or maintain at least one radio access bearer (RAB) between the mobile terminal and the core-network node.

Abstract: The invention proposes a method for configuring a network, wherein the network comprises a plurality of network sections, the method comprising the steps of accessing (S2) data from network sections; forming (S3) groups of network sections using a clustering method by using at least part of the accessed data as input data; and processing (S4) parameter on network section group level. By this method, the operation load during optimising a network consisting of a large number of cells can be greatly reduced. The invention also proposes a corresponding network optimising system.
