The present invention discloses a method for controlling a UE to select a cell in a radio communication system. The method includes: after an MBMS session stops, each UE determines whether to reselect the cell according to a cell reselection indication from a network side. The present invention discloses at the same time another method for controlling a UE to select a cell in a radio communication system. By adopting the methods disclosed, it is possible to disperse the UEs in the cell of preferred frequency layer at the end of an MBMS session so as to reduce the load of the cell of the preferred frequency layer, improve the service quality, and prevent the UE from making frequent unnecessary cell reselection.
