'EU-Alert' in Release-11

In the recently concluded 3GPP CT-50 in Istanbul, EU-Alert was adopted as part of Rel-11. The EU-Alert is introduced under Public Warning System (PWS) in parallel with Earthquake and Tsunami Warning System (ETWS).

PWS was introduced in Rel-9 and I blogged about it here. ETWS has been around since Rel-8 and was blogged here.

In fact EU-Alert is sent as part of the Cell Broadcast Message (CBS) using new identifiers. For more details see 3GPP TS 23.401.

The following is an old video from CHORIST project, which was instrumental in providing details of working of this EU-Alert system.

Why is CMAS for a UE in untrusted non-3GPP network is being handled?
Is it not required?
