Feature Configuration

To configure this feature, use the following configuration:

config 
    amf-global 
        call-control-policy policy_name 
            policy ue-ctx-transfer 
                allow-interplmn-supi-transfer { true | false } 
                horizontal-key-derivation { true | false } 
                use-source-key { true | false } 
                use-source-pcf { true | false } 
                exit 
            timers 
                context-transfer-guard 
                    n14-interface value guard_time_value 
                    end 

NOTES:

  • call-control-policy policy_name —Configure the Call Control Policy.

  • policy ue-ctx-transfer—Configure the ue-ctx-transfer Policy.

  • allow-interplmn-supi-transfer { true | false } —Specify true or false. If configured true, the source AMF sends UE context with SUPI. The default value is false .

  • horizontal-key-derivation { true | false } —If configured true, the source AMF generates a new key every time. The default value is false

  • use-source-key { true | false } —If configured true, the target AMF uses a key received from the source AMF. The default value is true

  • use-source-pcf { true | false } —If configured false, the target AMF sends pcfReselectedInd as true in TransferUpdate and the source AMF clears the PCF association. The default value is true

  • context-transfer-guard —Specify the context transfer guard timer. The AMF starts this timer on receiving the TransferUpdate. On expiry, the AMF clears the PDUs locally.

  • n14-interface value guard_time_value —Specify the interface n14-interface value in seconds. It must be an integer in the range of 0—35712000. The default value is zero (0).
