The UEi shall apply the following rules for E-UTRANi inter-frequencies and inter-RATi frequencies which are indicated in system information and for which the UE has priority provided as defined in 5.2.4.1:
- For an E-UTRAN inter-frequency or inter-RAT frequency with a reselection priority higher than the reselection priority of the current E-UTRA frequency the UE shall perform measurements of higher priority E-UTRAN inter-frequency or inter-RAT frequencies according to [10].
- For an E-UTRAN inter-frequency with an equal or lower reselection priority than the reselection priority of the current E-UTRA frequency and for inter-RAT frequency with lower reselection priority than the reselection priority of the current E-UTRAN frequency:
- If Snonintrasearch is sent in the serving cell and SServingCell > Snonintrasearch UE may choose not to perform measurements of E-UTRAN inter-frequencies or inter-RAT frequency cells of equal or lower priority.
- If SServingCell <= Snonintrasearch or Snonintrasearch is not sent in the serving cell the UE shall perform measurements of E-UTRAN inter-frequencies or inter-RAT frequency cells of equal or lower priority according to [10].
Where SServingCell is the Srxlev-value of the serving cell.

----Note that s-NonIntraSearch is sent in SIB-3
