In the LTE system, a UE must detect and monitor the presence of multiple cells and perform cell reselection to ensure that it is "camped" on the most suitable cell. A UE "camped" on a particular cell will monitor the System Information and Paging of that cell, but it must continue to monitor the quality and strength of other cells to determine if cell reselection is required.
