Method and apparatus for cell selection in wireless communication system

A wireless device in a wireless communication system comprising:

• a transceiver;
• a memory;
• and
• at least one processor operatively coupled to the transceiver and the memory, and configured to:
• control the transceiver to receive, 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;
• determine a movement pattern of each of the plurality of mobile cells based on the location information and the identifier information;
• determine a mobile cell among the plurality of mobile cells for a cell selection based on the movement pattern;
• and
• perform 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.

A computer-readable medium having recorded thereon a program for performing each step of a method on a computer, 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;
• determining 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.
