Abstract
A method of enabling a provision of public warning system, PWS, messages to a user equipment, UE, device via a non-3GPP radio network including establishing an internet protocol security, IPSec, tunnel connection from the UE device to a non-3GPP interworking function, N3IWF, via a non-3GPP, N3GPP, radio access technology, requesting from a first core network, CN, entity a provision of public warning system, PWS, messages; and providing the first CN entity with information about a location of the UE device.
Claims10
A method of enabling a provision of public warning system (PWS) alert messages to a user equipment (UE) device via a non-3GPP (N3GPP) radio network, the method comprising:
- establishing an internet protocol security (IPSec) tunnel connection to the UE device from a non-3GPP interworking function (N3IWF) via a non-3GPP (N3GPP) radio access technology;
- receiving by a first core network (CN) entity from the UE device a request for provisioning of the public warning system (PWS) alert messages;
- receiving from the UE device by the first CN entity information about a location of the UE device;
- subscribing the UE device at the first CN entity to a group to which the PWS alert messages are provided by the first CN entity based on a notification area relating to the group, the notification area comprising the location of the UE device, and
- transmitting to the UE device the PWS alert messages having a source or a target address relating to an area comprising the notification area as a result of the subscribing of the UE device, via the IPSec tunnel.
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.
