context: a TAI list, the ICF shall store the received values and associate them both the current received SUPI to 5G-GUTI association and any future association until: - A subsequent IEFAssociationRecord is received which updates the PEI, GPSI, NCGI or TAI list values. - The old PEI / GPSI / NCGI / TAI list shall be retained in association with previous SUPI to 5G-GUTI associations until those associations are deleted from cache. - New PEI / GPSI / NCGI / TAI list shall be used in association with both the association(s) with which it was received and any subsequent associations until another update is received. - All SUPI associations for which the PEI / GPSI / NCGI / TAI list is valid are deleted from the cache. When the ICF receives a query request from the IQF as defined in clause 7.6.2.3, the ICF shall search available identifier associations (both active associations and those marked for deletion in the cache) for a match. The ICF shall be able to use both time and TAI (as a single TAI
description: The Tracking Area Identifier (TAI) is a critical network attribute used in the context of identifier association event handling, as defined in 3GPP TS 33.128. It is utilized by the Interworking Function (ICF) to manage associations between different identifiers and store received values for future reference.
explanation: The TAI is classified as a Parameter due to its role as a network attribute used for identifier association event handling, which involves storing and managing received values in relation to other identifiers like SUPI and 5G-GUTI.
