5.2.3 Service Flows
Remote UEs with no user interface are deployed to control machines in a factory and are connected to 3GPP network via a relay UE. An earthquake suddenly occurs close to the factory and the relay UE receives a PWS message. The relay UE receives a PWS message, and unconditionally forwards the PWS message to the remote UE...
2e4def7229d8545d814f4132a20a55ee
22.969
5.2.4 Post-conditions
Remote UEs with no user interface take pre-defined actions (e.g. shut off the power) in time that made machines in the factory less damaged from the earthquake.

5.2.6 Potential Requirements
The remoteUE with no user interface shall be able to support the reception of the information that is related to an event or a disaster notified by PWS message and is transmitted from the relay UE.

5.3 Use case: relay UE for indirect network connection of remote UEs
2e4def7229d8545d814f4132a20a55ee
22.969
5.3.1 Description
This use case describes a scenario where a relay UE that provides an indirect network connection to remote UEs transmits a PWS message to the remote UEs as they are located in an area where the PWS message is broadcast from the 3GPP network.
2e4def7229d8545d814f4132a20a55ee
22.969
5.3.2 Pre-conditions
Bob and Mary go out to the sea by taking their yacht where there is a relay UE on the deck of the yacht to provide indirect network connection to remote UEs inside the steel cabin of the yacht.
2e4def7229d8545d814f4132a20a55ee
22.969
5.3.3 Service Flows
The PWS message is broadcast and the relay UE receives the PWS message notifying that a storm is coming to the area where the yacht is located while Bob and Mary sleep in the steel cabin of the yacht. The UEs that Bob and Mary have with them could not receive the PWS message directly because the UEs are located inside ...
2e4def7229d8545d814f4132a20a55ee
22.969
5.3.4 Post-conditions
Bob and Mary woke up due to the warning alarm from the UEs that they have with them inside the cabin and come back to the port before the storm arrives at the area where they are.

5.4 Use case: UE with different user interface
2e4def7229d8545d814f4132a20a55ee
22.969
5.4.1 Description
This use case describes a scenario where the user interface of the mobile device is different from the conventional user interface of the mobile phone, e.g. augmented reality based user interface or hologram based user interface. Because the network functionalities to broadcast a PWS message need to be kept as unchange...
2e4def7229d8545d814f4132a20a55ee

5.4.2 Pre-conditions
The UE with different user interface (e.g. augmented reality based or hologram based user interface) are connected to 3GPP system. A warning event or disaster is identifiable from information that can be extracted from the PWS message. Pre-defined content or procedure is mapped in the UE with different user interface t...

5.4.3 Service Flows
Sally is on holidays in Seoul and her device, a UE with user interface that is different from the conventional user interface of a mobile device (e.g. augmented based or hologram based user interface), helps her find a good restaurant at Gangnam area. Suddenly an earthquake occurs near Seoul so a PWS message is broadca...
2e4def7229d8545d814f4132a20a55ee
22.969
5.4.4 Post-conditions
Sally recognized in time about the earthquake occurred thanks to the notification of the device and not by the text-based public warning message itself.

6.1 Considerations on the improvement of the understandability of the PWS message
2e4def7229d8545d814f4132a20a55ee
22.969
6.1.1 Constraints inherent in the language-based and text-based PWS message
3GPP specified the requirements for Public Warning System in 3GPP TS 22.268 from 3GPP Release 8 onwards in order to let mobile users receive text-based PWS messages. Language-related requirements described in 3GPP TS 22.268 are as follows. NOTE 1: Requirements described in the section 5 (Earthquake and Tsunami Warning...

6.1.2 Potential requirements proposed for the improvement of the understandability of the PWS message
For mobile users with disabilities, the user interface of UEs that are used by them is extended by UE accessibility functions. The most effective presentation of the warning indication may be different from what is normally defined for mobile users without disabilities. Considering such difference, following potential ...

22.969
6.2.1 Applicability review of existing PWS requirements
UEs with different or no user interface or with different UE roles didn’t exist when existing PWS requirements were specified in 3GPP TS 22.268 [2] so some of existing PWS requirements might not be applicable and need to be revised or to add some additional requirements for UEs with different or no user interface or wi...
