8.1.17 ETWS primary notification with security procedure<br />

UE<br />

UTRAN<br />

ETWS PRIMARY NOTIFICATION<br />

WITH SECURITY<br />

8.1.17.1 General<br />

Figure 8.1.17-1: ETWS primary notification with security<br />

The ETWS primary notification with security procedure is used to transfer an ETWS primary notification to the UE.<br />

The ETWS PRIMARY NOTIFICATION WITH SECURITY message is received via the dedicated control channel<br />

(DCCH).<br />

The UE may receive the ETWS PRIMARY NOTIFICATION WITH SECURITY message via DCCH, when the UE is<br />

in a state where it is configured to receive DCCH. The UTRAN may use this option to send an ETWS primary<br />

notification to the UE when RRC is configured from upper layers to receive the ETWS primary notification either. The<br />

UE behaviour is specified in subclause 8.1.17.4.<br />

8.1.17.2 Initiation<br />

The UTRAN may initiate the ETWS primary notification with security procedure towards UEs in connected mode<br />

CELL_DCH state by sending the ETWS PRIMARY NOTIFICATION WITH SECURITY message on DCCH using<br />

UM or AM RLC.<br />
