Mandatory GSM Elementary files and procedures

Source: Nokia

1	Introduction
The purpose of this input paper is twofold:

•	To list all the mandatory GSM SIM files and procedures, according to GSM 11.11 v7.1.0.  This is done to enable a USIM to fulfil the requirement of providing a UMTS subscriber access to a GSM network (see e.g. 22.00 v1.5.0 Ch. 9 and 22.01 v3.3.0 Ch. 14.1), as these files and procedures must be a mandatory part of the USIM application.
•	To propose a list of GSM SIM optional files which are recommended to be part of a USIM application. This part also propose to move some files from the TELECOM directory to the USIM.

2	Mandatory GSM files

Mandatory files at MF level:

EFICCID (ICC Identification)	

Mandatory files at the GSM application level:

EFLP (Language preference)	
EFIMSI (IMSI)	
EFKc (Ciphering key Kc)	
EFHPLMN (HPLMN search period)	
EFSST (SIM service table)	
EFBCCH (Broadcast control channels)	
EFACC (Access control class)	
EFFPLMN (Forbidden PLMN's)	
EFLOCI (Location information)	
EFAD (Administrative data)	
EFPhase (Phase identification)	
EFKcGPRS (GPRS Ciphering key KcGPRS)	
EFLOCIGPRS (GPRS location information)	

Mandatory files at the DFTELECOM level:

None.

Mandatory procedures:

The list of procedures at the SIM/ME interface in GSM network operation is as follows: 
General Procedures:
‑	Reading an EF	ME
‑	Updating an EF	ME
‑	Increasing an EF	ME

SIM management procedures:
‑	SIM initialization	ME
‑	GSM session termination	ME
‑	Emergency call codes request	ME
-	Extended language preference request	ME
‑	Language preference request	ME
‑	Administrative information request	ME
‑	SIM service table request	ME
‑	SIM phase request	ME

CHV related procedures:
‑	CHV verification	MMI
‑	CHV value substitution	MMI
‑	CHV disabling	MMI
‑	CHV enabling	MMI
‑	CHV unblocking	MMI
GSM security related procedures:
‑	GSM algorithms computation	NET
‑	IMSI request	NET
‑	Access control information request	NET
‑	HPLMN search period request	NET
‑	Location Information	NET
‑	Cipher key	NET
‑	BCCH information	NET
‑	Forbidden PLMN information	NET

3	Recommended files
The following GSM files are proposed to be present on the UICC either in the USIM application, under the MF or in the Telecom dir. 

It should be noted that some of the files should/will change format but the generic information should be there. 

Files at MF level:
The EFDIR must be present under the MF to hold a list of the applications in the UICC. 
The EFELP should be there to enable every possible language.

Files at USIM level:
Files containing the following information should be present in the USIM application.

EFCBMID	For SAT CB download	
EFCBMI 	For Cell Broadcast	
EFECC	Emergency call codes	
EFCBMIR	For Cell Broadcast	
Files to be (re)moved from the Telecom directory to the USIM application(s)	
EFFDN	Could be both common and USIM appl. specific.	
EFSMS	Could be both common and USIM appl. specific.	
EFSMSP	Could be both common and USIM appl. specific.	
EFSMSS	Could be both common and USIM appl. specific.	
EFCCP	Follows their respective “ancestor” files or they could be generic	
EFSDN	Should be USIM appl. specific.	
EFBDN	Should be USIM appl. specific.	
EFEXT1-4	Follows their respective “ancestor” files
