9.2.21  STOP-WARNING-INDICATION Request/Indication |R12|Word‑p. 48
Parameter Reference Presence
Message Type 9.3.28M
Message Identifier 9.3.1M
Serial-Number 9.3.3M

This primitive is sent by the MME to the CBC.
The STOP-WARNING-INDICATION Request/Indication primitive is to report to the CBC the Broadcast Cancelled Area List the MME has received from the eNodeB in a KILL RESPONSE. If the MME has received a KILL RESPONSE without a Broadcast Cancelled Area List IE, then the eNodeB ID shall be included in the Broadcast Empty Area List instead. The MME may aggregate Broadcast Cancelled Area Lists it receives from eNodeBs.
If the MME interfaces with multiple CBCs (i.e. has active SCTP associations established with multiple CBCs), the MME shall forward the same STOP-WARNING-INDICATION primitive to all CBCs.
This primitive is sent by an AMF via the PWS-IWF to the CBC.
The STOP-WARNING-INDICATION Request/Indication primitive is to report to the CBC the Broadcast Cancelled Area List the AMF has received from the NG-RAN nodes in a PWS CANCEL RESPONSE. If the AMF has received a PWS CANCEL RESPONSE without a Broadcast Cancelled Area List IE, then the NG-RAN node ID shall be included in the Broadcast Empty Area List NG-RAN instead. The AMF may aggregate Broadcast Cancelled Area Lists it receives from NG-RAN nodes and send them to the CBC via the PWS-IWF.
If the message is received from an MME then the Broadcast Cancelled Area List IE may be present. If the message is received from an AMF via the PWS-IWF then the Broadcast Cancelled Area List NG-RAN IE may be present.
The Broadcast Cancelled Area List IE or Broadcast Cancelled Area List NG-RAN IE is included in the STOP-WARNING-INDICATION when stopping the broadcast was successful in at least one of the cells within the eNodeBs or NG-RAN nodes.
The Broadcast Empty Area List IE shall be included in the STOP-WARNING-INDICATION when the MME has received at least one KILL RESPONSE without Broadcast Cancelled Area List IE.
The Broadcast Empty Area List NG-RAN IE shall be included in the STOP-WARNING-INDICATION when the AMF has received at least one PWS CANCEL RESPONSE without Broadcast Cancelled Area List IE.

9.2.22  RESTART-INDICATION-E-UTRAN Request/Indication |R12|

Parameter Reference Presence

The RESTART-INDICATION-E-UTRAN message is sent by the MME to the CBC upon receipt of a PWS Restart Indication from an eNodeB, to indicate that the PWS service is restarted in one or more or all cells served by an eNodeB, i.e. the service has become operational and no warning message data is available for these cell(s). Upon receipt of that message, the CBC shall reload the cells if required. See subclause 15A.1 of TS 23.007.
If the MME interfaces with multiple CBCs (i.e. has active SCTP associations established with multiple CBCs), the MME shall forward the same RESTART-INDICATION-E-UTRAN message to all CBCs.
The RESTART-INDICATION-E-UTRAN primitive is sent by a PWS-IWF to the CBC, triggered by the AMF sending a RESTART-INDICATION-NG-RAN message to the PWS-IWF upon receipt of a PWS Restart Indication from a NG-RAN node. The RESTART-INDICATION-E-UTRAN message indicates to the CBC that the PWS service is restarted in one or more or all cells served by a NG-RAN node, i.e. the service has become operational and no warning message data is available for these cell(s). Upon receipt of that message, the CBC shall reload the cells if required.
If the indication is received from the PWS-IWF then the Restarted Cell List NG-RAN IE, the Global RAN Node ID IE and List of NG-RAN TAIs IE shall be present and the Restarted Cell List IE, the Global eNB ID IE and List of TAIs IE are populated with a dummy value (all zeros).
The List of TAIs or List of NG-RAN TAIs, and the Emergency Area ID List shall contain the Tracking Area IDs and Emergency Area IDs (if any) that are configured for the restarted cells listed in the Restarted Cell List, or in the Restarted Cell List NG-RAN.
Upon receiving a RESTART-INDICATION-E-UTRAN shortly after a preceding one, if:
  1. the same Restarted Cell List NG-RAN is included in both messages; or
  2. the same Restarted Cell List is included in both messages and the Restarted Cell List NG-RAN is absent in both messages;
the CBC shall consider the RESTART-INDICATION-E-UTRAN as a duplicate message and shall ignore it.

The FAILURE-INDICATION-E-UTRAN message is sent by the MME to the CBC upon receipt of a PWS Failure Indication from an eNodeB, to indicate that ongoing PWS operation in one or more or all cells served by that eNodeB has failed.
If the MME interfaces with multiple CBCs (i.e. has active SCTP associations established with multiple CBCs), the MME shall forward the same FAILURE-INDICATION-E-UTRAN message to all CBCs.
The FAILURE-INDICATION-E-UTRAN message is sent by a PWS-IWF to the CBC, triggered by the AMF sending a FAILURE-INDICATION-NG-RAN message to the PWS-IWF upon receipt of a PWS Failure Indication from a NG-RAN node. The FAILURE-INDICATION-E-UTRAN message indicates to the CBC that ongoing PWS operation in one or more or all cells served by that NG-RAN node has failed.
If the indication is received from a PWS-IWF then the Failed Cell List NG-RAN IE and the Global RAN Node ID IE shall be present and the Failed Cell List IE and the Global eNB ID IE are populated with a dummy value (all zeros).
