10 Relay of Warning Notification
22.2683GPPPublic Warning System (PWS) requirementsRelease 18TS
10.1 Service description
Requirements specified in the clause 10 do not apply for US WEA and Japan ETWS.
3GPP system specified the relay functionality that is useful to extend the coverage supported by 3GPP system. With the relay functionality, PWS-UEs and ePWS-UEs that play the role of a relay UE or a remote UE conform to behaviours specified in the clause 10 when receiving a Warning Notification via the relay functionality.
10.2 Requirements for the relay functionality
A remote ePWS-UE and a remote PWS-UE shall be able to support the reception of a Warning Notification that is transmitted from an UE that supports the relay functionality.
A remote ePWS-UE and a remote PWS-UE shall be able to automatically suppress duplicated notifications. A duplicate is a repetition of a same notification as determined by unique parameters.
A remote ePWS-UE and a remote PWS-UE receiving a Warning Notification transmitted via an UE that supports the relay functionality shall behave in the same fashion as if it received the message directly from a 3GPP network.
An UE that supports the relay functionality shall unconditionally forward the Warning Notification broadcast received from the network.
