The present document specifies the Access Stratum (AS) part of the Idle and Inactive Mode procedures applicable to a UE. The present document specifies the model for the functional division between the NAS and AS in a UE.
The present document applies to all UEs that support at least New Generation Radio Access Network, including multi-RAT UEs as described in 3GPP specifications, in the following cases:
- When the UE is camped on a New Generation Radio Access Network cell;
- When the UE is searching for a cell to camp on;
NOTE: When the UE is camped on or searching for a cell to camp on belonging to other RATs, the UE behaviour is described in the specifications of the other RAT.
