5.2 Cell selection and reselection 

5.2.1 Introduction 

UE shall perform measurements for cell selection and reselection purposes as 

specified in [10]. 

The NAS can control the RAT(s) in which the cell selection should be performed, for 

instance by indicating RAT(s) associated with the selected PLMN, and by maintaining a 

list of forbidden registration area(s) and a list of equivalent PLMNs. The UE shall select 

a suitable cell based on idle mode measurements and cell selection criteria. 

In order to speed up the cell selection process, stored information for several RATs 

may be available in the UE. When camped on a cell, the UE shall regularly search for a 

better cell according to the cell reselection criteria. If a better cell is found, that cell is 

selected. The change of cell may imply a change of RAT. Details on performance 

requirements for cell reselection can be found in [10].
