10.1 Contents of the EFs at the MF level

11.113GPPRelease 1999Specification of the Subscriber Identity Module - Mobile Equipment (SIM-ME) InterfaceTS

There are only two EFs at the MF level.

10.1.1 EFICCID (ICC Identification)

This EF provides a unique identification number for the SIM.

Identifier: ‘2FE2’

Structure: transparent

Mandatory

File size: 10 bytes

Update activity: low

Access Conditions:

10 bytes

‑ Identification number

Contents:

according to CCITT Recommendation E.118 [18]. However, network operators who are already issuing Phase 1 SIM cards with an identification number length of 20 digits may retain this length.

Purpose:

card identification number.

Coding:

BCD, left justified and padded with ‘F’; after padding the digits within a byte are swapped (see below). However, network operators who are already issuing Phase 1 SIM cards where the digits within a byte are not swapped may retain this configuration.

10.1.2 EFELP (Extended language preference)

This EF contains the codes for up to n languages. This information, determined by the user/operator, defines the preferred languages of the user in order of priority. This information may be used by the ME for MMI purposes.

This information may also be used for the screening of Cell Broadcast messages in a preferred language, as follows.

When the CB Message Identifier capability is both allocated and activated, the ME selects only those CB messages the language of which corresponds to an entry in this EF or in EFLP, whichever of these EFs is used (see subclause 11.2.1). The CB message language is defined by the Data Coding Scheme (DCS: see TS 23.038 [12]) received with the CB message. The ME shall be responsible for translating the language coding indicated in the Data Coding Scheme for the Cell Broadcast Service (as defined in TS 23.038 [12]) to the language coding as defined in ISO 639 [30] if it is necessary to check the language coding in EFELP.

Coding:

each language code is a pair of alpha-numeric characters, as defined in ISO 639 [30]. Each alpha-numeric character shall be coded on one byte using the SMS default 7-bit coded alphabet as defined in TS 23.038 [12] with bit 8 set to 0.

Unused language entries shall be set to ‘FF FF’.
