The location of the UE in RRC_IDLE is known to the network at the level of tracking areas, which consist of cells. This chapter looks briefly at the processes performed in RRC_IDLE. The services provided to UEs can be classified into normal service, limited service and operator service. Cells are also categorized, depending on the service supported on the cell as suitable cell, acceptable cell, barred cell and reserved cell. There are three states applicable to the UEs in the RRC_IDLE such as the CampedNormally state, the CampedOnAnyCell state, and the AnyCellSelection state. For public land mobile network (PLMN) selection, cell selection, and cell reselection, several types of PLMN are considered. These include, home PLMN (HPLMN), registered PLMN (RPLMN), equivalent PLMN (EQPLMN) and Equivalent HPLMN (EHPLMN) by the UE.
