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 value guard_time_value 
                end 

NOTES:

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

    context-transfer-guard value must be an integer in the range of 0—35712000. The default value is zero (0).
