Configuring Tracking Area Identity Group
The SMF provides configuration to define the supported list of Tracking Areas and Tracking Area Ranges for a PLMN. Upon enabling this configuration, the SMF sends the configured Tracking Area Identity (TAI) to the NRF during the SMF Service Registration.
To define multiple TAI groups with different names, use the following sample configuration.
config
profile tai-group tai_group_name
mcc mcc mnc mnc
tac list [ tac_value1 tac_value2 tac_valueN ]
tac range start tac_start_value end tac_end_value
end
NOTES:
-
profile tai-group tai_group_name : Specify the name of the TAI Group to enter the profile configuration.
-
mcc mcc_value : Specify the mobile country code.
-
mnc mnc_value : Specify the mobile network code.
-
tac list [ tac_value1 tac_value2 tac_valueN ] : This keyword allows you to configure—
-
multiple PLMNs and TAC values within the specified TAI group
-
a maximum number of 16 PLMNs within the specified TAI group
-
a maximum number of 64 TAC values under a PLMN
-
-
tac range start tac_start_value end tac_end_value : This keyword allows you to configure—
-
multiple TAC range values
-
a maximum number of 64 TAC ranges under a PLMN
ImportantThe SMF ignores TAC range values if the start range value is greater than the end range value.

The SMF derives TAC list and TAC range from TAI group or NCGI group configuration. If the NCGI list already includes a TAC, you can skip the TAC configuration under TAI group. However, if the TAC is associated to a different UPF, this behavior is not applicable.
