1. A method performed by a wireless device in a wireless communication system, the method comprising:
receiving, from each of a plurality of mobile cells, location information related to each of the plurality of mobile cells and identifier (ID) information related to each of the plurality of mobile cells;
estimating a movement pattern of each of the plurality of mobile cells based on the location information and the identifier information;
determining a mobile cell among the plurality of mobile cells for a cell selection based on the movement pattern; and
performing the cell selection to the determined mobile cell,
wherein the cell selection to the mobile cell is determined based on a cell selection reception (RX) level for the mobile cell and a cell selection quality value for the mobile cell,
wherein the cell selection RX level is determined based on at least one of:
an offset temporarily applied to the mobile cell;
a measured cell RX level value for the mobile cell;
a minimum required RX level in the mobile cell; or
an offset to the minimum required RX level in the mobile cell, and
wherein the cell selection quality value for the mobile cell is determined based on at least one of:
an offset temporarily applied to the mobile cell;
a measured cell quality value for the mobile cell;
a minimum required quality level in the mobile cell; or
an offset to the minimum required quality level in the mobile cell.
