Feature Description
The SMF provides an optional configuration to configure the supported list of Tracking Areas and Tracking Area Ranges for a Public Land Mobile Network (PLMN). When a new configuration is present, the SMF sends the configured Tracking Area Identity (TAI), that is, TAIList and TAIRangeList, to the Network Function (NF) Repository Function (NRF) during the SMF Service Registration.
Important | Any change in the configuration results in SMF Service update towards the NRF with the new configured TAIList and TAIRangeList values. The PLMN value sent in the NRF discovery message remains the same as the PLMN configured on the SMF. |
