Configuring the Handover from 5G to 4G
To configure this feature, use the following configuration:
config
amf-services service_name
peer-mme tai-match priority priority_value mcc mcc_value mnc mnc_value tac tac_value [ to end_tac_value ] address mme_address
exit
instance instance-id instance_id
endpoint protocol
vip-ip ip_address
exit
endpoint gtp
nodes node_replicas
retransmission { max-retry maximum_number_of_retries | timeout retransmission_timeout_value }
end
NOTES:
-
peer-mme tai-match priority priority_value mcc mcc_value mnc mnc_value tac tac_value [ to end_tac_value ] address mme_address
-
peer-mme tai-match priority priority_value —Specify the priority value.
-
mcc mcc_value —Specify the three-digit Mobile Country Code. Must be an integer with three digits.
-
mnc mnc_value —Specify the two or three-digit Mobile Country Network. Must be an integer with three digits.
-
tac tac_value —Specify the Tracking Area Code value. Must be an integer in the range of 1-65535.
-
to end_tac_value—Specify the Tracking Area Code range for peer MME.
-
address mme_address—Specify the peer MME address.
-
-
nodes node_replicas —Specify the replica nodes for resiliency.
-
max-retry maximum_number_of_retries —Specify the number of request retry attempts. Must be an integer in the range 0–5 (default value: 3). To disable retransmission, set this value to zero (0).
-
timeout retransmission_timeout_value —Specify the retransmission interval in seconds. Must be an integer in the range 0–10 (default value: 2). To disable retransmission, set this value to zero (0).
