Patent ID: 7965672

Claim:
A method for cell selection by a radio network controller which exclusively controls cells of a communication service area including a plurality of macro cells and a plurality of micro cells divided from each of the macro cells, the method comprising the steps of: when the number of times of cell reselection during a cell reselection time period given to a particular User Equipment (UE) located within a micro cell exceeds a predetermined maximum number of times, determining if a sum of actual occupancy time intervals of the particular UE in Node Bs, services of which the particular UE has used up to then, is smaller than a predetermined value; and when the sum of actual occupancy time intervals of the particular UE in Node Bs, services of which the particular UE has used up to then, is smaller than the predetermined value, determining that the particular UE is in a low speed state and maintaining the micro cell as a service cell for the particular UE, wherein the predetermined value corresponds to an average occupancy time interval, and the average occupancy time interval is calculated according to an average speed of the particular UE.
