Paging in Idle Mode

Paging in Idle Mode

A paging type 1 message is sent via the Paging Control Channel (PCCH) of the cell and is used to transmit paging information to a number of users in the cell. This is done by sending a number of paging records with a different UE identity from the dedicated UE.

The message can direct the RRC to send a notification to NAS about an incoming call or direct the RRC to read the MIB in the cell by changing the value tag, which would imply change of some information in the SIB in the cell. The notification meant for NAS also contains the domain for which the terminating call has been requested.
