Feature Description
The SMF supports failure handling of the Charging Function (CHF) server. In the event of the failure of an online CHF server, the SMF relays the charging information to the offline CHF server.
For a seamless transfer of charging information, the SMF invokes the configurations associated with the CHF failure handling profile. When the failure handling is configured, the SMF continues the session with the selected CHF configured in another profile.
For information on how to select the charging server, see the CHF Selection section in the Subscriber Charging chapter of this guide.
