Configuring the RAT Restriction

To configure this feature, use the following configuration:

config 
    amf-global 
        call-control-policy call_control_policy_name 
            rat-type-restrictions { EUTRA | NR | VIRTUAL | WLAN | override-udm-restrictions } 
            local-cause-code-map rat-type-restriction 5gmm-cause-code { 5GS-services-not-allowed | no-suitable-cells-in-tracking-area | plmn-not-allowed | roaming-not-allowed-in-this-tracking-area | tracking-area-not-allowed | restricted-service-area } 
            end 

NOTES:

  • call-control-policy call_control_policy_name —Specify the call control policy name to apply the restriction at AMF as RatType .

  • rat-type-restrictions { EUTRA | NR | VIRTUAL | WLAN | override-udm-restrictions } —Specify the RAT type. The default RAT type is NR. Configuring the RAT restriction is optional. The AMF restricts the NR access to the subscribers using or associating with the Call Control Policy.

    When the RAT type is configured as override-udm-restrictions , the AMF ignores the UDM defined restrictions and considers the locally configured restrictions.

  • local-cause-code-map rat-type-restriction 5gmm-cause-code { 5GS-services-not-allowed | no-suitable-cells-in-tracking-area | plmn-not-allowed | roaming-not-allowed-in-this-tracking-area | tracking-area-not-allowed | restricted-service-area } —Specify the 5GMM cause code.

  • The default option for RAT type restrictions is plmn-not-allowed for the rat-type-restrictions command.
