Patent Number Title Of Patent Date Issued
6711515 Robust and efficient method for smoothing measurement results March 23, 2004
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,
6466790 Cell selection in a radio network October 15, 2002
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, 63.sub.1 . . . 63.sub.N) about the mobile station's serving cell
6400951 Handover and call setup in a mobile communication system June 4, 2002
An handover method and a call setup method in a mobile communication system. A cell to be assigned to the mobile station (MS) is selected on the basis of the measurement results and the special cell list. The selected cell is set as the target cell of the handover for the mobile stat
6321083 Traffic hot spot locating method November 20, 2001
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
6285884 Method and arrangement for making a handover decision in a mobile communication system September 4, 2001
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 meas
6006093 Traffic control method in a hierarchical communication system December 21, 1999
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
5913169 Cellular mobile station system June 15, 1999
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 t
5907808 Handover with fast moving mobile station detection between a microcell and a macrocell May 25, 1999
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, whi
5884176 Fast handover by preassigning neighboring candidate cells March 16, 1999
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
