Routing of warning messages to the appropriate eNodeBs in the indicated Tracking Area.

Routing of warning messages to the appropriate NG-RAN nodes in the indicated Tracking Area.

Transferring CBS information to each appropriate BTS via a sequence of 4 SMS BROADCAST REQUEST messages or 1 SMS BROADCAST COMMAND message (see 3GPP TS 48.058 [11]), indicating the channel which shall be used.

The Node B has no functionality regarding CBS. This implies that CBS messages do not have to be transmitted explicitly to the Node Bs for further processing.

Not applicable.
