23.2213GPPArchitectural requirementsRelease 17TS
A CN node requests paging only for UE in CS-IDLE state or PS IDLE state. Paging from a CN node is done independent of the service state of the UE in the other CN domain type.
CS and PS paging is co-ordinated within the UTRAN. Details on how the co-ordination is achieved and the parameters to be provided by the CN are specified in TS 25.413 [9]. The procedures required between the UTRAN and UE are in TS 25.331 [5].
