TSG-T3 (USIM) meeting #3		Tdoc T3-99065
Helsinki, 17th - 19th March, 1999

Approved Report of the 
3GPP TSG-T WG3 (USIM) meeting #2
hosted by Giesecke & Devrient in
Munich, 17 - 19 February 1999
Secretary:	Michael Sanders (ETSI)
Chairman:	Dr Klaus Vedder (Giesecke and Devrient)

1	Opening of the Meeting
The second meeting of the 3GPP TSG-T WG3 on USIM issues (hereafter referred to as T3) was opened by the Convenor, Dr. Klaus Vedder, who welcomed delegates to Munich.
2	Roll Call of Delegates
The meeting was attended by 25 delegates representing 7 countries. A list of the delegates can be found in Annex A of this report.
3	Input Documents / Agenda
T3-99035 contains the first draft of the agenda. Several new documents were added and three new agenda items "Third UICC size", "Project Team support" and "Inter system compatibility issues" were added. The approved version can be found in T3-99050 and also in annex B in this report.
4	Approval of the report of T3 #1
T3-99034 contains the draft meeting report from TSG-T3 #1, held in Nice on the 25 - 27 January, 1999. After several clarifications, the report was approved and was made available in T3-99049.
5	Results from ETSI SMG #28
T3-99041 is the status report by SMG9 to SMG #28. T3-99042 is a summary of the decisions of SMG #28 concerning SMG9 and the work of T3. The document was presented by the SMG9 chairman. In particular, the revised ToR of SMG9 after the "handover" of the UMTS work to 3GPP and a slightly modified SMG position paper on the removable USIM adding a sentence on plastic roaming were approved by SMG #28 as presented (see T3-99041). It was further noted that the 1.8 Volt SIM/ME specification (GSM 11.18) and the SIM Conformance Test Specification (GSM 11.17) had now been approved by SMG.
T3 then agreed to base its specifications on the latest versions of Release 98 as approved by SMG #28. These are GSM 11.11 v. 7.2.0 and GSM 11.14 v. 7.2.0.
6	Election of T3 chairman
T3-99044 contains a summary of the 3GPP working procedures that apply to the election of chairman and vice-chairmen for TSG working groups. It was noted.
T3-99053 contains a nomination from Giesecke & Devrient for Dr. Klaus Vedder to become chairman of T3. The secretary, who had taken over the chair from the Convenor for the election of the Chairman, stated that he had not been notified of any other nominations. As a result, Dr. Klaus Vedder was elected as chairman by acclamation. Dr. Vedder accepted the election and thanked the delegates for their confidence in him. He then took over the chair from the Secretary.
T3-99054 contains a nomination from T-Mobil for Dr. Günter Maringer to become vice-chairman of T3. The secretary stated that he had not been notified of any other nominations. As a result, Dr. Günter Maringer was elected as vice-chairman by acclamation. When asked by the Chairman Dr. Maringer accepted the election to the post of T3 vice-chairman and thanked the delegates for support.
The meeting agreed that if any further nominations for vice-chairman are received, an election for a second vice-chairman could be held at a future meeting, with the usual 21 days notice.
7	Issues involving ARIB 2G specifications
T3-99040 contains the ARIB specification of a SIM for the PDC system. A splinter group reviewed the document. The following points and conclusions were noted:
-	in clause, 8, different authentication mechanisms (compared to GSM) are used;
-	clause 11 contains the EF definitions. It was noticed that some information normally stored in the GSM HLR is instead stored on the PDC SIM. Some clarification is needed to avoid the problems experienced when dual band MEs are used with a SIM setup for GSM 900. The linking of different subscriptions and identities would be done on the network rather than on the SIM;
-	the PDC ADNs (under DF PDC not DF TELECOM) also have a field that indicates that the dialling number is secret. The ME interprets that FIELD and only displays the number if the user has entered a special code;
-	a removable SIM is an optional feature for PDC terminals in Japan, but is not widely used. It is estimated that there may be only 10 000 PDC SIMs currently in use;
-	for a dual mode PDC / UMTS UICC, it was proposed that these would probably be separate applications on the UICC whereas for a GSM / UMTS UICC, they would have to be more closely integrated.

8	Elaboration of 3GPP USIM Specification
8.1	Mechanical/Electrical Interface
T3-99045 is a discussion document about a new smaller size UICC. It proposes that the Chip Scale/size Package be considered as a new package (physically not backwards compatible with the existing Plug-in SIM) for the UICC. 
T3-99058 is a discussion document containing two proposals for a new size UICC which would both be backwards compatible (to different extents) with the existing Plug-in SIM. 
A broad discussion on the issue of a third size SIM concluded that:
-	the new UICC package should be such that is removable without the use of special tools;
-	the new UICC package should be able to accept the existing chip size (i.e., up to approximately 5 x 5 mm). This would allow the same functionality regardless of UICC size;
-	there is a requirement to allow the ICCID (and service provider logo) to be printed on the device.

The discussion was then postponed as the possible new size has only priority 2 and input is required from TSG-SA. 
8.2	Security Principles
T3-99043 is an LS from TSG-SA3 in reply to the LS from T3 to SA3 (in T3-99027) on the use of variable length of security related parameters. It states that they are examining the issue and that they will inform T3 when they have decided about the length and number of security parameters to be transferred across the physical interface between the USIM and terminal. The LS was noted.
8.3	ADNs and Usage of index files
No new input documents on this topic were made available to T3 #2.
8.4	File Management
T3-99051 is a proposal describing two methods of sharing DFs. A third proposal can be found in 3GPP 21.11 v1.0.0 (T3-99002). The sharing of DFs will be necessary if there is more than one USIM on the UICC. An initial discussion on DF sharing concluded that the requirements for file sharing need to be more closely defined.
8.5	General issues
T3-99038 contains a review of GSM 11.11 clause 10 "Contents of the Elementary Files" for inclusion into the 3GPP specification. It was clarified that the file IDs had been replaced by ## to indicate that they may need to change in the future.
T3-99046 contains a review of GSM 11.11 clause 6 "Logical model" for inclusion into the 3GPP specification.
T3-99047 contains a review of GSM 11.11 clause 8 "Description of the functions" clause 9 "Description of the commands".
During T3 #2, a splinter group reviewed all three documents. T3-99053 is the report from that group. The conclusions in the report were endorsed by the plenary session subject to the following points:
-	regarding section 6.3, it was clarified that the size of a record within a linear-variable file is fixed at personalisation and could not be changed there-after. T3 would like to consider "dynamic" linear-variable files where the file size can change after personalisation;
-	regarding section 8, it was noted that the technique described allows separate algorithms to run and separate parameters for the algorithms;
-	regarding section 9.2, it was noted that there was in fact a requirement in UMTS 22.00 v2.0.0 clause 9 stating "The UICC shall be capable of supporting SIM and USIM applications";
-	regarding section 9.2.18, the comment that "GET RESPONSE does not apply when T=1 is used" needs to be further investigated;
-	regarding 9.4.1, further investigation is required into whether response codes should be aligned with GSM 11.11 or ISO/IEC standards.

A discussion of the T3 schedule to produce 3GPP specifications concluded that:
-	the 3GPP version of 21.11 "USIM and UICC requirements" should be ready by April 1999;
-	the first draft of the SMG9 generics document specifying the electrical and physical interface should be ready by April 1999.

9	USIM functional characteristics
T3-99036 is a discussion document that proposes the addition of material to 3GPP 21.11 regarding the ‘Storage of call detail’ and ‘Support of profile exchange’. A splinter group met during T3 #2 to discuss the document - it was agreed that these concepts should be included in 3GPP 21.11 but that some modification would be required. A proposed change to 3Gpp21.11 was drafted accordingly and is contained in T3-99063.
T3-99055 describes a study of the ARIB USIM requirements (in T3‑99005, as presented to T3 #1) as it had been agreed at T3 #1 that ARIB requirements raised in T3-99005 which were not yet contained in 3GPP 21.11 should be highlighted. During a discussion of T3-99055, it was noted that:
-	there was no requirement to be backwards compatible with GSM phase 1;
-	regarding the global plastic roaming, it was pointed out that significant changes would also be required to other 3G systems if this is to be realised. It is more likely that two (or more) separate applications would be required on an ICC in order to support more than one IMT-2000 system;
-	regarding 2.1 (OTA service provisioning), this requirement would need to be endorsed by the TSG-SA1 (services) and TSG-SA3 (security). It was clarified that there was a notable distinction between downloading an application(s) within a USIM and downloading a new USIM;
-	regarding 2.2 (Support of updating and controlling security data and mechanism), this requirement also needs to be endorsed by TSG-SA1 (services). However, it was agreed that an LS is not required at the moment as input documents (covering 2.1 and 2.2) are expected from ARIB members on these topics to SA1 and SA3.

To achieve different 3G applications on one ICC, T3 agreed to find out a way to have a common physical/electrical interface with the other 3G system, i.e. in 3GPP2. An LS in T3‑99061 to TSG-T asking a relationship between 3GPP and 3GPP2 was drafted and approved.

T3-99039 is a discussion document which proposes some modifications to the ADN description in 21.11. In particular, several features that are currently (or in the near future) supported by PDC mobiles are listed. They are:
-	two names per record;
-	user definable groupings;
-	500 records;
-	secret record(s);
-	multiple phone numbers per record;
-	E-mail address field;
-	synchronisation between the ADNs in USIM and external phone book in, for instance, a personal organiser (this requires further discussion at a future meeting).

A splinter group discussed this document and produced a list of requirements and whether they should be optional or mandatory. The group discussed two methods of handling ADNs - 1) a similar method as is currently done in the SIM and 2) using an execution environment (e.g. MExE or SIM toolkit) to handle the entries. It was concluded that it is unlikely that the 3GPP would agree to a new requirement that ALL mobiles would have to support MExE or SIM toolkit, so it was concluded that it would be better to follow method 1). 
On the subject of ADNs, it was commented that it would be better to use a multinational character set (e.g. UCS2) for all alpha IDs as a default from the beginning. For those European alphabets based on Latin characters, this would mean an overhead of one character per alpha ID. However, it needs to be examined whether the USC2 alphabet (ISO/IEC 10646-1) as is used in GSM 11.11, accurately represents the characters currently used in, for instance, the Japanese alphabet. Mr Barnes indicated that he would bring the UCS2/UNICODE standard to the next T3 meeting for information.
T3-99063 contains all the changes to 3GPP 21.11 version 1.1.0 as contained in T3-99032. These changes were endorsed  with the following modifications:
-	deletion of two lines of superflous text below subclause 9.2.5;
-	addition of a new subclause 9.2.6 "Mode of alerting".
Version 1.2.0 of 3GPP 21.11 incorporates these changes and was made available in T3-99064.
10	Any Other Business
10.1	Project team support
T3-99048 is a discussion document proposing that due to the expertise and knowledge that resides within PT SMG (the project team that currently provides support to the committee SMG), it is strongly recommended that support for SMG and 3GPP from PT SMG is continued. It is also recommended that sufficient funding is obtained to (as a minimum) continue, or increase the level of support from PT SMG. These proposals were endorsed by T3 and an LS informing TSG-T of these conclusions was approved in T3-99062.
10.2	Inter system compatibility issues.
T3-99059 is a document listing several scenarios with the USIM compatibility with different 2G and 3G systems. Delegates were requested to study it so that at T3 #3, a clearer set of requirements could be established.
T3-99060 is a proposed LS to TSG-SA1 (Services) requesting clarification regarding the requirement for USIMs and SIMs operating in GSM and 3G systems. However, discussion on the document concluded that the issue should be more closely studied by T3 before seeking advice from other 3GPP groups and so the LS was postponed.
A general discussion of the high level requirements as to the types of terminals in which a USIM was required to work concluded that the 22.xx series should be used as the basis for discussion. Backwards compatibility, especially with respect to file selection would have to be carefully examined. Regarding inter PLMN handover, it was concluded that T3 should aim to provide the hooks for such functionality even though it is recognised that inter PLM handover is not required for phase 1 UMTS systems.
To achieve different 3G applications on one ICC, T3 agreed to find out a way to have a common physical/electrical interface with the other 3G system, i.e. in 3GPP2. An LS in T3‑99061 to TSG-T asking for liaison between 3GPP and 3GPP2 was drafted and approved.

10.3	Rapporteurs for T3 specifications
During a discussion on the specifications that would be produced by T3, it was concluded that rapporteurs should be appointed to ensure their speedy production. The meeting agreed by acclamation that Günter should be the rapporteur for the requirements specification (i.e., 3GPP 21.11) and that ARIB would provide a rapporteur for the 3GPP USIM/UICC specification.

ANNEX C	Access to 3GPP documents
This document briefly outlines some of the more important locations of information that all T3 members should be aware of. 
3GPP email lists:
To receive information about T3 issues, all delegates and other interested parties MUST register for email list 3GPP_TSG_T_WG3. This can be done by sending an email to LISTSERV@LIST.3GPP.ORG with the following single line of text in the body of the message:
subscribe  3GPP_TSG_T_WG3  YourFirstName  YourLastName

There are many other 3GPP email lists that may also be of interest. Go to http://www.3gpp.org/e‑mail.htm for further information.
If at any time you would like to confirm which lists you are currently a member of, just sent a message to  LISTSERV@LIST.3GPP.ORG with the following single line of text in the body of the message:
QUERY *

Email archives:
All 3GPP lists have an associated archive of every email sent via that list. Information on how to access the archive are sent to you when you subscribe to the list. This means that if you have temporary email problems, or have just joined the group, you can check to see if you have missed any messages. The easiest was to search the archive is first to request a list of all messages sent to the particular group you are interested in. For example, to get a list of message sent via the 3GPP_TSG_T_WG3 list between 1st January 1999 and the current date, send the following command to LISTSERV@LIST.3GPP.ORG:
search * in 3GPP_TSG_T_WG3 since January 1999
As well as a list of emails sent, you receive instructions about how to retrieve the emails.
It is expected that a more user-friendly interface will be made available (by Q2 1999) to access the email archives. When available, it will be accessed at http://list.3gpp.org/
Meeting invitations and meeting calendar:
The central location for all information relating to the 3GPP meeting calendar and the corresponding meeting invitations can be found at: http://www.3gpp.org/Meetings.htm
In particular, the meeting invitations to all WG3 meeting will be made available under the directory: ftp://ftp.3gpp.org/TSG_T/WG3_USIM/INVITATIONS/
Documents on the server:
All documents submitted to T3 meetings will be made available on the 3GPP document server in a directory (related to the number of the meeting) under: ftp://ftp.3gpp.org/TSG_T/WG3_USIM/ 
e.g. the documents for  T3 meeting #2 can be found at: ftp://ftp.3gpp.org/TSG_T/WG3_USIM/TSGT3_02
