    摘要: The present invention relates to prioritizing special cells in cell selection in a cellular radio network. In a cellular radio network one or more cells provide a subscriber with special services or tariffs not offered to all subscribers. These cells are called subscriber's special cells. The mobile station measures an average reception level and calculates by means of them cell selection parameters on the basis of which the best cell is selected. In accordance with the invention, when the mobile station detects that the cell is one of cells of a special cell list stored in a memory, it checks first if the cell fulfils a minimum requirement of cell selection on the basis of the measured signal level. If the minimum requirement is fulfilled, the mobile station manipulates the calculation of the cell selection parameter of a special cell to the effect that the selection probability of a special cell is improved with respect to a normal cell. In a preferred embodiment of the invention, the manipulation of the calculation comprises a step of adding a predetermined margin to the measured signal level of a special cell before the cell selection parameter is calculated. This will minimize the possibility that the mobile station would accidentally be camped on a normal cell when it is within the area of a special cell.

    摘要: The present invention relates to selection of sites of a communication system for measurement units that are for measuring a feature of wireless signals so that the location of a wireless station may be determined based on the measurement. Each measurement unit provides a measurement coverage. In the method a first set of information is defined, said first set relating to sites that are possible locations for the location measurement units and to the coverage provided by the site if it is provided with a measurement unit. A second set of information is defined that relates to signalling environment within the sites. Based on the defined first and second sets of information, a third set of information is defined, said third set associating each site with access entities of the communication system. Based on the third set of information, appropriate sites can be selected for the location measurement units.
