As specified in TS 24.229 a ME includes the list of IARIs (IMS Application Reference Identifiers) for the IMS applications it intends to use when sending
an initial registration or when sending subsequent registrations to the IMS in the form of a SIP REGISTER request.
This EF contains a list of IARIs associated with active applications installed on the UICC that are included in the SIP REGISTER request in accordance with the procedures of TS 24.229.
NOTE: If this file is present in both the USIM and the ISIM, the file in the ISIM is used. It is assumed that the
presence of this file in the USIM when an ISIM is present on the UICC is an incorrect configuration of
The EF UID is used to uniquely identify a record and to be able to keep track of the entry in the phone book. The terminal assigns the (UID) when a new entry is created. The value of the UID does not change as long as the value of the PBID remains the same. The UID shall remain on the UICC, in EF UID, until the PBID is regenerated. This means that when a phone book entry is deleted, the content of the linked information (e.g. ADN, E-MAIL...) shall be set to the personalization value 'FF...FF'. But the UID-value of the deleted record shall not be used when a new entry is added to the phonebook until the PBID is regenerated, but it shall be set to a new value.
If/when the PBID is regenerated, all UIDs for the entry in the phone book shall be assigned new values starting from 1.
If more than one EF UID exists (i.e. multiple phone book file sets) then all values of UIDs used in that phone book shall be unique over all phone book file sets within that phone book. The new value of the UID for each entry shall then be kept until the PBID is regenerated again.
This EF contains the coding for preferred PLMNs to be used for WLAN PLMN Selection. This information is
determined by the user and defines the preferred PLMNs of the user in priority order. The first PLMN entry indicates the highest priority and the n-th
PLMN entry indicates the lowest. It shall be possible to store at least the number of
PLMNs specified in TS 24.234.
This EF contains the Unique Smartcard Filter of the Smartcard used for Smartcard Broadcast Provisioning function as defined in OMA-TS-BCAST_Services-V1_1-20100914-C (Mobile Broadcast Services). USF defines the group of Smartcards the Smartcard belongs to and its position in the group.
This file contains the user preferred list of WLAN specific identifier (WSID) for WLAN selection in priority order. The first record indicates the highest priority and the n-th record indicates the lowest. This file is used for WLAN selection and shall store a list of at least the number of WSIDs specified in TS 24.234.
