Outline of the presentationOutline of the presentation

• The USIM related requirements as (currently) listed by TSG-SA

• Browsing through the relevant service requirement documents.

• Summary of the identified requirements.

• NOKIA's proposal for the USIM application content

• A comparison of the GSM and the USIM file structures as agreed at the last TSG-T3 meeting.


3GPP specifications analysed3GPP specifications analysed

• The following UMTS documents are analysed for USIM requirements:

• UMTS 22.00 v2.0.0, "UMTS phase 1".

• UMTS 22.01 v3.5.0, " Service aspects; Service principles".

• UMTS 22.05 v3.1.0, "UMTS services and capabilities".

• draft UMTS 22.29 v1.0.0, "Handover between UMTS and GSM or other Radio systems".

NOTE: All these documents have been presented for TSG-SA and will be used as base line for the UMTS standard.


22.00 v2.0.022.00 v2.0.0

9 USIMIn the first phase of UMTS, the USIM shall be developed on the basis of the phase 2+ release 99 GSMSIM. The additional requirements for the phase 1 UMTS USIM are as follows :

1) USIM shall provide new and enhanced security features (e.g. mutual authentication...) as defined bySMG10.

2) The UMTS mobile terminal shall support phase 2 and phase 2+ GSM SIMs as access modules toUMTS networks. The services that can be provided in this case may be limited to GSM like servicesprovided by that UMTS network. UMTS mobile terminals shall not support 5V SIMs. It shall be upto the UMTS network operator to accept or reject the use of GSM SIM as access modules in itsnetwork.

3) It shall be possible to have multiple applications on the UMTS IC Card (UICC). There shall be asecured and easy mechanism for application selection. An authorised access for each application ismandatory, however it shall be possible to have shared directories between applications whereappropriate. The UICC shall be capable of supporting SIM and USIM applications.

4) Simultaneous activation of several USIMs on one mobile terminal need not be supported in UMTSphase 1.

5) A standardised mechanism allowing highly secure transfer of applications and/or associated datato/from the UICC shall be supported in UMTS phase 1.

NOTE: There are NO requirements here indicating that a GSM terminal shallbe able to support a UICC+SIM, or UICC+USIM or UICC+SIM+USIM!


22.01 v3.5.022.01 v3.5.0

• Ch. 9.2: "(For UMTS Phase 1) It is required that is shall be possible to identify UMTS users using GSM identities, namely IMSI, MSISDN and possibly TMSI and IMEI."

• Conclusion: the GSM identities may be reused!

• Ch. 9.5:"It shall be possible for several numbers to be associated with a single subscription on a single UICC."

• Comment: One IMSI many MSISDN's.

• Ch. is devoted to USIM issues.


22.01 v3.5.022.01 v3.5.0

• Ch. 11.1.1:

• Every USIM shall have a unique identity and shall be associated with one and only one home environment.

• It shall be possible for a home environment to uniquely identify a user by the USIM.

• The USIM shall be used to provide security features.

• For access to UMTS services, provided via a UMTS home environment, a valid USIM shall be required.

• The USIM shall reside on a UICC, UMTS shall adopt both of the GSM SIM card physical formats. New UMTS terminals may require other formats also. USIM specific information shall be protected against unauthorised access or alteration.

• It shall be possible to update USIM specific information via the air interface, in a secure manner.


22.01 v3.5.022.01 v3.5.0

• 11.1.2:

• it shall be possible to have one or more user profiles associated with a number (should this be per subscription?)

• the profiles should be controlled by e.g. a PIN mechanism.

• Each profile shall have it's own address (e.g. IMUN).

• 11.1.3:

• In Phase 1 it is only required to support one USIM application on the UICC.

• The standard shall not prevent that two USIM applications from different home environments reside on the same UICC.

• 11.2:

• The physical aspects of the UICC will be handled outside the UMTS specification.

• The UICC shall support access to services via GSM and UMTS.


22.01 v3.5.022.01 v3.5.0

• 11.2.1 The UMTS UICC and Applications other than the USIM:

• Other applications than the USIM shall be able to reside on the UICC

• each application. may require it's own security mechanisms.

• Applications shall reside in their own logical/physical domain.

• Applications shall be separate, I.e. some kind of firewall mechanism shall exist between applications.

• Applications may share information such as a common address book.

• Address applications over the air.

• 11.2 Terminals and Multiple UICCs

• The standard shall support multiple UICCs (in phase 2).


22.01 v3.5.022.01 v3.5.0

• 14 Evolution.

• "UMTS shall provide some mechanisms which permit pre UMTS users to roam easily onto UMTS and access the services. See Figure 5 for clarification.

• UMTS shall provide some mechanisms which permit UMTS users to roam easily onto pre-UMTS systems and access the services."

• 17 Handover:

• "It shall be possible for users to be handed over between UMTS networks operated by different operators subject to appropriate roaming/commercial agreements. Handover between networks operated by different network operators is not required for UMTS phase 1."

• "Handover between UMTS and GSM systems (in both directions) is required, even if this requires changes to GSM specifications. In addition, a generic solution may be implemented in UMTS which allows calls to be handed over between UMTS and other pre-UMTS systems in both directions. For UMTS phase 1, handover between UMTS and GSM networks operated by different network operators is not required."


22.05 v3.1.022.05 v3.1.0

• 9.2 Execution environment:

• The execution environment requires SAT.

NOKIA’s proposal for the USIM applicationNOKIA’s proposal for the USIM application

NOKIA proposes that a separate application under control of 3GPP is created. For phase 1 it will be assigned a special file id e.g. ‘7FXX’ and will reside directly under the MF but for later phases the multi-USIM issue must be handled

BASIC USIM/UICC FUNCTIONALLITYBASIC USIM/UICC FUNCTIONALLITY

• This USIM application will have the following main features:

Provide access to UMTS systems including security and confidentiality.

Provide access to GSM systems – by providing Ki, A8/3, A5 and other mandatory GSM features.

Provide means to enable handover between GSM and UMTS systems (in phase 1 only intra-PLMN handover will be supported).

• For the card (UICC) the following is proposed:

It will have a DIR file that is a collection of application templates containing an AID, an application name and a path to the application.

A GSM application (under 7F20) can coexist with a USIM application on the same card – it is proposed that the two applications can not belong to the same operator, i.e. they are independent.


USIM questionsUSIM questions

Q Why create a USIM application with the listed functionality?

A The main reason for creating a USIM application is to create a 3GPP context and to prepare for later phases were multiple USIM applications may reside on the same card which will incur the need to separate all functionality belonging to a specific subscription (operator) in a separate application.

Consider the alternative scenario:

• For every system an operator has a license to there will be an application!

• This would imply that an operator with GSM and UMTS licenses has two applications.

Q What happens when cards containing multiple USIM’s emerges – should only the first operator with licenses to both systems get a GSM application, i.e. who owns ‘7F20’?

Conclusion: Therefore the complete functionality should be located in a separate application.
