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).
