8. A mobile communication network adapted to transmit public warning system (PWS) alert messages, to a user equipment (UE) device over an internet protocol security (IPSec) tunnel connection from a non-3GPP interworking function (N3IWF) of the mobile communication network to the UE device via a non-3GPP (N3GPP) radio access technology,
the mobile communication network being adapted
to receive capability information from the UE device, the capability information informing about a capability of the UE device to receive PWS alert messaging, wherein the capability information may indicate a desire of a user of the UE device to receive such messaging;
to receive location information from the UE device, the location information informing about a location of the UE device;
to subscribe the UE device to a group to which the PWS alert messages are provided by the mobile communication network based on a notification area relating to the group, the notification area comprising the location of the UE device, and
to transmit to the UE device the PWS alert messages having a source or a target address relating to an area comprising the notification area via the IPSec tunnel, as a result of the subscribing of the UE device.
