Abstract
A method (200, 300, 400) according to the invention is a method for determining a condidate cell for an active set, where the quality factor of each cell in the active set is determined (202), a quality factor of a test cell is determined (203), and the test cell is accepted (205) as a candidate cell for the active set if an acceptance criterion is fulfilled. The method is characterized in that the acceptance criterion is selected (201) so that for a certain first quality factor of a test cell and for a certain first set of quality factors, consisting of quality factors of the cells in a first active set, the acceptance criterion has the same value as for a certain second quality factor of a test cell and for a certain second set of quality factors, consisting of quality factors of cells in a second active set, when the first quality factor is equal to the second quality factor multiplied with any finite number and the first set of quality factors is the same as a set formed of the quality factors belonging to the second set of quality factors multiplied with the same finite number. The invention relates also to an arrangement, to a mobile station and to a network element where decisions about accepting a cell as a candidate cell for the active set are done.
