摘要：
Methods and apparatus are provided for efficiently operating of USIM FIDs and SFIs under USIM ADF. In one novel aspect, the UICC of the mobile equipment comprises one or more generation dedicated files (DFs), and one or more generation-dedicated elementary files (EFs) are stored in each corresponding generation DF. In one embodiment, at least one of the generation-dedicated EFs is assigned an SFI. In another embodiment, each generation-dedicated EFs is assigned an SFI. In yet another embodiment, all generation-dedicated EFs for one generation are stored in corresponding generation DF. In one embodiment, at least one of the 5GS EFs is associated with at least one of: 5GS 3GPP location information, 5GS non-3GPP location information, 5GS 3GPP Access NAS Security Context, non-5GS 3GPP Access NAS Security Context, and 5G authentication keys.
