+# --- 1 Scope
+
+This document defines the requirements of the USIM (Universal Subscriber Identity Module) and the IC card for 3G (UICC). These are derived from the service and security requirements defined in TS 22.100 [1] and TS 22.101 [2]. The USIM is a 3G application on an IC card. It inter-operates with a 3G terminal and provides access to 3G services. This document is intended to serve as a basis for the detailed specification of the USIM and the UICC, and the interface to the 3G terminal.

+
+# --- 4 General requirements
+
+The UICC shall be either a removable hardware module or a non-removable separate hardware module embedded in the ME. The USIM on a UICC shall contain an identity which unambiguously identifies a subscriber.
+
+For access to 3G services, a UICC containing a valid USIM shall be present at all times, other than for emergency calls.
+
+The specifications shall support the security requirements as defined in 3GPP TS 33.102 [7].
+
+The USIM shall provide storage for subscription and subscriber related information.
+
+The UICC/USIM may also contain applications which use the features defined in the USIM Application Toolkit specification 3GPP TS 31.111 [6].
+
+# --- 5 Security requirements
+
+The USIM shall be used to provide security features. If the UICC is removed from the 3G terminal, the service shall be terminated immediately. The functions of the USIM include authenticating itself to the network and vice versa, authenticating the user and providing additional security functions as defined in 3GPP TS 33.102 [7].
+
+The USIM shall be unambiguously identified.
+
+Means shall be provided to prevent fraudulent use of stolen UICCs.
+
+It shall not be possible to access data intended for USIM internal use, e.g. authentication keys.
+
+Further details of the following requirements are given in 3GPP TS 33.102 [7].
+
+## 5.1 File access conditions
+
+Actions, such as READ, UPDATE on UICC data shall be controlled by access conditions. These shall be satisfied prior to the action being performed.
+
+Since a UICC may contain multiple (3G and non-3G) applications, a flexible method of controlling file access shall be provided.
+
+## 5.2 User authentication
+
+The USIM shall support means to authenticate the user, to provide, for example, protection against the use of stolen cards. For the USIM, authentication shall be performed by the verification of a numeric PIN of four (4) to eight (8) decimal digits.
+
+A function to disable user authentication may exist which may be inhibited by the application provider, in which case the user shall always use the PIN. Otherwise, the user may decide whether or not to make use of the user authentication function. If disabled, the user authentication function remains disabled until the user specifically re-enables it.
+
+Following correct PIN presentation, the ME may perform functions and actions on USIM data, which are protected by the relevant access condition.
+
+If an incorrect PIN is entered, an indication shall be given to the user. After three (3) consecutive incorrect entries the relevant PIN is blocked, i.e. functions and actions on data protected by the access condition shall no longer be possible, even if between attempts the UICC has been removed, the USIM has been deselected or the ME has been switched off. Once a PIN is blocked, further PIN verifications shall be denied.
+
+The USIM shall support a mechanism for unblocking a blocked PIN. Unblocking of a PIN is performed by using the relevant PIN Unblocking Key.
+
+PINs, but not Unblock PINs, shall be changeable by the user following correct entry of either the current PIN or Unblock PIN.
+
+The Unblock PIN shall consist of eight (8) decimal digits and shall not be changeable by the user. If an incorrect Unblock PIN is presented, an indication shall be given to the user. After ten (10) consecutive incorrect entries, the Unblock PIN shall be blocked, even if between attempts the UICC has been removed, the USIM has been deselected or the ME has been switched off. Unblocking of a blocked PIN shall not be possible.
+
+It shall not be possible to read PINs or Unblock PINs.
+
+## 5.3 User data stored in ME
+
+Subject to the exception below, all user related information transferred into the ME during network operations shall be deleted from the ME after removal of the UICC, deselection of the USIM, deactivation of the ME, or following an electrical reset of the UICC. This includes any data that was transferred to the ME by USIM Application Toolkit commands.
+
+User related security codes such as PIN and Unblock PIN may only be stored by the ME during the procedures involving such a code and shall be discarded by the ME immediately after completion of the procedure.
+
+Optionally, an ME may retain some less security-sensitive data at UICC removal, USIM deselection or ME switch-off. Such data are e.g. SMS, ADN/SSC, FDN/SSC, LND. These data, when stored in the ME, shall only be readable/retrievable if the same USIM is reactivated (as determined by the IMSI). If the IMSI is retained in the ME for this purpose, it shall be stored securely and shall not be able to be read out.
+
+## 5.4 Authentication
+
+A means shall be specified to mutually authenticate the USIM and the network by showing knowledge of a secret key K which is shared between and available only to the USIM and in the user's Home Environment. The method is composed of a challenge/response and key establishment protocol combined with a sequence number-based one-pass protocol for network authentication.
+
+## 5.5 Data integrity of signalling elements
+
+Some signalling information elements are considered sensitive and must be integrity protected. An integrity function shall be applied on certain signalling information elements transmitted between the ME and the network.
+
+The 3GPP Integrity Algorithm (UIA) is used with an Integrity Key (IK) to compute a message authentication code for a given message. The setting of IK is triggered by the authentication procedure. IK shall be stored on the USIM.
+
+## 5.6 User identity confidentiality
+
+A mechanism shall be specified to provide user identity confidentiality by means of a temporary identity.
+
+## 5.7 Length of security parameters
+
+In order to allow for enhancements of the security level in 3G, the following requirements shall be covered:
+
+- all security-related parameters for 3G shall be accompanied by a length indicator;
+- the USIM shall support variable-length security parameters.
+
+If the USIM supports the GSM security mechanisms in addition to 3G security, fixed length security parameters according to 3GPP TS 51.011 [8] shall be supported in addition.
+
+# --- 6 Logical issues
+
+## 6.1 Application selection
+
+In a multiapplication environment, a flexible application selection method is required. The application identifier defined in ETSI TS 101 220 [5] should be used for application selection. Direct application selection, including selection by partial DF name and the EF<sub>DIR</sub> concept of ISO/IEC 7816-4 [12] shall be followed. In particular, a mechanism for the ME and the UICC shall be specified in order to allow the user, when the ME is in idle mode, to select and activate one application amongst those which are available and supported by the ME (this will permit the user to choose, for instance, between 2 different USIM applications). At switch on, the last active USIM shall be automatically selected. The last active USIM shall be stored on the UICC. By default if there is no last active USIM defined in the UICC, the user shall be able to select the active USIM amongst those available on the UICC.
+
+## 6.2 Simultaneous access
+
+A mechanism shall be specified for simultaneous access to several files or applications.
+
+# --- 7 Service Requirements
+
+## 7.1 Void
+
+## 7.2 Data transfer
+
+A mechanism allowing highly secure transfer of applications and/or associated data to/from the UICC/USIM shall be specified in line with the requirements in 3GPP TS 22.101 [2]. This requires a secure transfer mechanism.
+
+## 7.3 Application execution environment
+
+An application execution environment may exist on the UICC/USIM which includes functionality defined in 3GPP TS 31.111 [6].
+
+## 7.4 Profile exchange
+
+A mechanism for the ME, the USIM and the network to exchange service capabilities shall be specified. The following exchange of service capabilities may occur:
+
+- ME services capabilities may be provided to the USIM/UICC;
+- USIM/UICC services capabilities may be provided to the ME (and thus potentially to the network);
+- network services capabilities may be provided to the USIM/UICC via the ME.
+
+## 7.5 Version identification
+
+A means for identification of the version of the USIM shall be provided.

+
+The ME shall have the capabilities of initiating a warm reset as defined in ISO/IEC 7816-3 [11]. The UICC shall support warm reset as defined in ISO/IEC 7816-3 [11].
+
+NOTE2: The warm reset is used during a session when there is a need to restart the USIM due to internal modifications of data caused by user actions or network data downloading.
+
+The UICC may indicate in the ATR to the warm reset that the specific mode is entered automatically, using the parameters that were used prior to the warm reset. In case of a cold reset, the UICC shall enter the negotiable mode.
+
+In addition to the T=0 protocol which is mandatory for the UICC and the ME, the T=1 protocol shall be mandatory for the ME. It is optional for the UICC.

+Thus, the specification shall allow the UICC to be used with a dual mode (GSM/ 3G) ME and a GSM ME for the provision of GSM service.
+
+# --- 12 Contact Manager
+
+## 12.1 General
+
+The Contact Manager provides an interface for the management of contact information including rich content without any structural limitations.
+
+There shall be a mechanism for the ME to detect that the UICC containing the Contact Manager has changed. This mechanism may be used by the ME to ask the user whether synchronization of data between the ME and the UICC Contact Manager should occur.
+
+This clause defines the functional requirements of the Contact Manager. An ME and a 3GPP application supporting the Contact Manager shall comply with all these requirements.
+
+## 12.2 Security requirements
+
+The Contact Manager may contain personal information. It shall be possible to restrict the access to this information to authorized users or entities (e.g. by binding the access to the verification of the USIM PIN).
+
+### 12.4.3 Interworking with the 3G Phone Book
+
+In case both the ME and the 3GPP application support both the 3G Phone Book (i.e. as defined in clause 10.2 of the present document) and the Contact Manager the Contact Manager shall be used. There shall be a mechanism for the 3GPP application to indicate the support of the Contact Manager.
+
+### 12.4.4 Content description
+
+#### 12.4.4.1 Number of contacts
+
+The Contact Manager specification shall not unreasonably restrict the number of contacts.
+
+#### 12.4.4.2 Contact structure
+
+The Contact Manager shall consist of contacts, which are made up of various fields (e.g. phone number, name, photo). A filtering mechanism according to OMA DS Field Filtering shall be supported.
+
+It shall be possible to have several instances of a field in a contact when appropriate (e.g. a contact may have two fax numbers).
+
+An extensible coding scheme shall be defined which allows to describe a contact including all its fields. An existing scheme (e.g. "vcard") shall be used, if appropriate.
+
+A minimum set of field types recognised by the 3GPP application and the ME shall be defined (e.g. name, phone number, URL, Email address, address, sound, pictures, notes).
+
+It shall be possible to store and associate multimedia information (stored on the 3GPP application) with a contact (e.g. photo, logo, video, ring tone, voice tag).
+
+It shall be possible to associate an icon or a label to each contact field type (e.g. associate an icon representing a phone to the number field. "Home address" could be configured as the label of the "mailing address" field type).
+
+It shall be possible to configure the structure and the display order of the contact fields (e.g. first name then Instant Messaging address then number, etc) depending on ME capabilities.
+
+#### 12.4.4.3 Group management
+
+It shall be possible to define new groups (e.g. My Tennis Club).
+
+It shall be possible to pre-define groups (e.g. Friend, Work, Family and VIP).
+
+It shall be possible to store and associate multimedia information (stored on the 3GPP application) with a group (e.g. photo, logo, video, ring tone, icon).
+
+It shall be possible to bind contacts to one or several groups.
+
+#### 12.4.4.4 User Action Management
+
+It shall be possible to configure a list of possible actions that could be proposed to the user when the contact is selected (e.g. Launch Browser, Send SMS, Send MMS, Instant messaging, Make a voice over IP call, Make a video call, Make a conference call, Game player, Send Email).
+
+### 12.4.5 Interface capabilities description
+
+An external and an internal interface to the Contact Manager shall be defined.
+
+The external interface between the Contact Manager and a UICC external entity, i.e. the ME, shall rely on a transport protocol layer that is independent of the physical interface (i.e. the ISO interface and the new high-speed interface). This is to allow the definition of one solution that can use either the existing ISO interface or the new high-speed interface. The external interface definition shall also ease interfacing the PC applications with the Contact Manager.
+
+Both the ME and the UICC shall be capable of initiating contact information synchronization based on a configurable policy. The internal interface allows other UICC resident applications to access the Contact Manager e.g. through a dedicated API. This enables the creation of additional services utilizing the Contact Manager data and properties. There shall be a mechanism for the user to allow or prevent remote access to the Contact Manager.
+
+The external and internal interface shall provide means to:
+
+- identify Contact Manager capabilities
+- perform the following operations on a contact or a group: create, retrieve, modify, delete, search
+
+In addition the internal interface shall provide mechanisms to:
+
+- register/deregister an UICC resident application to the Contact Manager.
+
+- allow a resident UICC application to access Contact Manager data and properties based on user permission.
+- allow the Contact Manager to notify events to registered UICC application and to pass event related information when applicable. Events notifying the applications shall include:
+  - contact information is modified locally
+  - contact information is modified remotely
+  - change of contact manager configuration
+
+### 12.4.6 Efficient browsing and searching
+
+The Contact Manager interfaces should allow efficient searching and browsing of the contacts (i.e. the user experience browsing the Contact Manager should be acceptable).
+
+### 12.4.7 Associated services
+
+#### 12.4.7.1 Memory management
+
+It shall be possible to determine the number of stored contacts and the amount of the available and used Contact Manager memory.

+
+The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows:
+
+Version x.y.z
+
+where:
+
+- x the first digit:
+  - 1 presented to TSG for information;
+  - 2 presented to TSG for approval;
+  - 3 or greater indicates TSG approved document under change control.
+- y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc.
+- z the third digit is incremented when editorial only changes have been incorporated in the document.
+
+# --- 1 Scope
+
+The present document identifies the 3GPP system specifications for Release 18. The specifications and reports of this Release have a major version number 18 (i.e. 18.x.y). The listed Specifications are required to build a system based on the Evolved Packet System.
+
+The high-level architecture of such a system is defined in 3GPP TS 23.002 [2] (figure 1b).
+
+# --- 2 References
