SIM

INTRODUCTION

In phrases of 'sales,' the (Subscriber Identity Module) SIM or higher the USIM, how it's miles called due to the fact 3G, ought to rank as ETSI's maximum a hit widespread. There are numerous billions of USIM playing cards bought every year in the international and no sign of a slowdown inside the call for them. The SIM Card has advanced into the 'Smart Card' with a developing style of applications and functions.

The USIM used in Digital Cellular Telecommunications Systems, like from GSM over 3G, 4G now to 5G is the entity that consists of the identity of the subscriber. When the SIM is positioned in a terminal or handset, users can sign in to a community.

The primary feature of the USIM is to authenticate the validity of a terminal while accessing the network. It additionally offers a means to authenticate the user and can additionally store other subscriber-associated facts or applications.

The ETSI paintings on Smart Cards, namely the evolvement of the capability of the UICC, that is the fundamental platform for the USIM, has evolved the USIM card in the direction of permitting contact-much fewer facts go with the flow for Identity, Security, and Payment applications.

OUR ROLE & ACTIVITIES

USIM standardization is concentrated in two committees:

3GPP-CT6

Technical Specifications Group, 'Core Network and Terminals' Working Group 6 (CT WG6) is liable for the specs of Smart Card-based totally network authentication programs, which includes the Subscriber Identity Module (SIM) that's utilized by 2G structures, the USIM (Universal Subscriber Identity Module) that is utilized by 3GPP™ systems  (from 3G to 5G), the ISIM (IM Services Identity Module) for authenticating to IMS and the HPSIM (Hosting Party Subscription Identity Module) apart from the security algorithms (developed via 3GPP™ Systems Aspects (SA) WG3).

The institution is liable for the standardization of the USIM/SIM for programs on top of the Smart Card Platform, the UICC specific by ETSI TC SCP.

ETSI technical committee clever card platform (SCP)

The Committee is responsible for the definition of the Smart Card Platform, the UICC.

USIM list

 

The Universal Subscriber Identity Module (USIM) is a 3GPP utility on UICC card. It interoperates with a 3GPP terminal and provides get right of entry to 3GPP services.

The USIM utility for 3GPP telecom network operation defines:

·        specific command parameters;

·        record systems;

·        contents of EFs (Elementary Files);

·        protection features;

·        software protocol to be used on the interface among UICC (USIM) and ME.

In addition, 3GPP™ defines the interface between the UICC and the Mobile Equipment and tactics for the USIM Application Toolkit (USAT):

·        the commands;

·        the utility protocol;

·        the required necessities on the UICC and ME for each manner.

UICC listing

3GPP™ specifies the interface among the UICC and the Terminal for 3GPP telecom network operation, which includes:

·        the necessities for the physical traits of the UICC;

·        the electric interface among the UICC and the Terminal;

·        the preliminary communique establishment and the shipping protocols;

·        the version which serves as a basis for the logical structure of the UICC;

·        the conversation commands and the processes;

·        the application impartial files and protocols.

3GPP TSG CT WG6 is especially relating to the specifications advanced with the aid of ETSI TC SCP for the UICC. However, 3GPP TSG CT WG6 is defining specific deviations or additions on a pinnacle of the UICC specifications developed with the aid of ETSI TC SCP.

ETSI SCP specifies the interface between the UICC and the terminal in fashionable, including

·        the necessities for the bodily traits of the UICC;

·        the electrical interface among the UICC and the terminal;

·        the initial conversation established order and the transport protocols;

·        the model which serves as a foundation for the logical structure of the UICC;

·        the communication commands and the processes;

·        the software independent documents and protocols.

KEYWORD

ISIM listing

The specification of the IP Multimedia Services Identity Module (ISIM) application for getting admission to IMS offerings contains:

·        specific command parameters;

·        document systems;

·        contents of EFs (Elementary Files);

·        protection features;

·        application protocol for use at the interface between UICC (ISIM) and Terminal.

This is to ensure interoperability among an ISIM and Terminal impartial from the respective manufacturer, card issuer, or operator.

HPSIM list

The specification of the Hosting Party Subscription Identity Module (HPSIM) software for access to Hosting Party services with the aid of an H(e)B contains:

·        precise command parameters;

·        document systems;

·        contents of EFs (Elementary Files);

·        safety features;

·        utility protocol for use at the interface among UICC (ISIM) and Terminal.

Contactless interface

The specification defines a radio frequency-impartial interface between the UICC and a Common Log File (CLF) thing in the terminal. This interface allows the card to be in use, even when the terminal is switched off for telecommunications use.

The ETSI SCP specification specifies the interface among the UICC and the CLF issue primarily based on a single twine protocol (SWP).
