摘要： The present invention relates to a method and an arrangement for determining a hot spot of telephone traffic in a cell. The invention uses simultaneously two basic measurements of digital radio systems; timing advance and adjacent cell measurement. Timing advance informs the distance of the mobile station from the base station but not the direction. On the basis of the measured signal strengths of adjacent cells it is possible to determine a set of possible locations of the mobile station when there is information about the coverage area of individual adjacent cells. When these measurements are used simultaneously, they exclude the inaccuracies of each other and enable very accurate location determination for monitoring traffic distribution. Timing advance is utilized to determine a set of circular, base-station-centric areas and adjacent cell measurements are utilized to determine the direction of the mobile station to the base

摘要： A traffic control method in a hierarchical mobile communication system which has mobile stations, a microcell network primarily intended to be used by mobile stations of a relatively lower transmitting power class, and a macrocell network which at least partly overlays the microcell network and is primarily intended to be used by mobile stations of a relatively higher transmitting power class to control traffic by a handover so that, apart from measurements of the radio path, the transmitting power class of the mobile station and the cell type of the neighboring cell are also taken into account in the handover decision so that only a neighboring cell of the cell type which the mobile station should primarily use on the basis of its transmitting power class is selected as the target cell for the handover.

摘要： A method for selecting a cell for a mobile station (MS) in a cellular telecommunications network, wherein the mobile station (MS) sends a radio station controller (BSC) measurement reports (6-4) comprising information (61, 631 . . . 63N) about the mobile station's serving cell and its neighbour cells. The mobile station or its subscriber is associated with at least one set of special cells called LSA cells. Information on the set of special cells is transferred to the radio station controller (BSC), and the mobile station (MS) at least participates in the transferring of information, preferably by sending an explicit list of its LSA cells or by including in at least one measurement report (6-4) a flag bit (62, 641 . . . 64N) indicating whether or not the cell in question is a special cell.

摘要： In a hierarchical micro/macro-cell network, a mobile station will be handed over from a microcell to a macrocell if a number of microcells recognize the mobile station as fast, so that the fast moving mobile stations do not cause a considerable number of handovers between microcells, which make the call control difficult. However, in order to avoid unnecessary switches up to macrocells, a mobile station and the call are handed over to a macrocell only when the mobile station is recognized as fast in a sufficient number of microcells.

摘要： A handover in a mobile communication system in which a mobile station measures the level of the downlink signals of the neighboring cells of a serving cell, and transmits the measurement results to a fixed network which measures the receive level of the mobile station uplink signal at the serving cell. At least some of the cells of the mobile communication system are assigned as chains of two or more cells. The fixed network reacts to a sudden drop in the receive level of the mobile station uplink signal below a predetermined threshold level at the serving cell by carrying out a handover to a chained cell on the basis of one or more of the latest signal level measurements.

摘要： A method for smoothing measurement results is presented, in which a parameter is calculated, using weight factors, from a number of measurement results in a sample. The parameter is a measure of the center of the sample and has a breaking point different from zero. Using this method, neither an increased number of measurements nor the removal of outliers are required when the reliability of individual measurement results is questionable due to interference, such as momentary burst noise.

摘要： The invention relates to a method and arrangement for making a handover decision in a mobile communication system of multilayer radio coverage, which comprises measuring at a mobile station (MS) a radio signal transmitted by a base station (BTS) of a microcell, and reporting the measurement results at substantially regular intervals. The invention is characterized by determining a relative speed for the mobile station on the basis of the number and classification of the measurement results received at substantially regular intervals. Mobile stations moving at a speed slower than the relative speed are defined as slow moving and commanded to register in the base station of a suitable microcell (A, B, C).

摘要： A cellular mobile station system wherein a handover decision is based on measuring downlink transmissions of a serving cell and neighboring cells by a mobile station. Adjacent cells are typically arranged to be partly overlapping so as to ensure there is a sufficient period of time for the reception and decoding of the downlink transmissions of the neighboring cells, as well as for a handover decision. In some of the cells, there may be terrain obstacles, buildings, tunnels or the like obstacles shadowing the downlink transmission of the neighboring cell so that overlapping is not sufficient between such a cell and a neighboring cell. A repeater or an antenna is provided for extending the coverage area of the downlink transmission of the shadowed neighboring cell in such a cell so as to allow an advanced transmission and decoding of the downlink transmission of the shadowed neighboring cell.
