Configuring RAT Type

To configure the RAT type with the local authorization under the DNN profile, use the following sample configuration:

config 
   profile dnn dnn_profile 
      authorization local rat-type [ nr | eutra | wlan ] 
      end 

NOTES:

  • authorization local : This command skips the SDM messages for EPS sessions only. Upon configuring this command under the selected DNN profile, the SMF skips the UDM interaction for fetch subscription. The SMF uses the values received in the Create Session Request message. The SMF skips the UDM interaction to receive ‘Subscribe-for-Notifications’ from the UDM.

  • rat-type [ nr | eutra | wlan ] : This keyword skips the following SDM messages based on the specified RAT type.

    • udm subscription-fetch

    • subscribe-to-notifications

    • unsubscribe-to-notifications

    Upon configuring the RAT type with authorization local command in the selected DNN profile, then for sessions on that RAT-type, the SMF skips the UDM interaction for the following messages:

    • udm subscription-fetch during session establishment

    • subscribe-for-notifications during session establishment

    • unsubscribe-for-notifications during session release

  • no authorization local rat-type [ nr | eutra | wlan ] : Disables the local authorization under the DNN profile.
