Understanding the Mobile World

The intertwining of telecom, banking, and M2M/IoT produce a new degree of complexity. We hope our COMPRION glossary helps you to get a good overview of all the connected terms, technologies, and concepts.

e

Element of the smart card file system. An EF has both a header and a body, and there are three different types: Transparent Elementary File (Transparent EF), Linear Fixed Elementary File (Linear fixed EF), and Cyclic Elementary File (Cyclic EF).

e7e60

The duration of a bit when sending data to chip cards. The absolute time duration for an etu is not fixed, but rather is defined as a function of the clock rate chosen for the chip card and of the clock rate conversion factors.

3a9b6
9b529

Standard format for machine-to-machine (M2M) applications. M2M applications have given rise to the possibility of having a Universal Integrated Circuit Card (UICC) that is embedded in a communication device in such a way that the UICC is not easily accessible or replaceable. The ability to change network subscriptions on such devices becomes problematic, thus necessitating new methods for secure and remote provisioning of access credentials on these embedded UICCs and managing subscription changes from one mobile network operator (MNO) to another.

e10fb
321da

Technical specification that specifies the interface between the UICC and the terminal.

0cf61
7efa9

Technical specification that defines the remote management of the UICC based on any of the secured packet structures specified in ETSI TS 102 225. It specifies the APDU format for remote management.

  • A set of commands coded according to this APDU structure and used in the remote file management on the UICC. This is based on ETSI TS 102 221.
  • A set of commands coded according to this APDU structure and used in the remote application management on the UICC. This is based on the GlobalPlatform card specifications.
ca656

Technical specification that defines the USB interface between a terminal and an ICC that may be supported by the UICC and terminal in addition to the interface specified in ETSI TS 102 221.

cb4c7
fe466

Technical specification that specifies a logical interface that enables contactless applications hosted on the Universal Integrated Circuit Card (UICC). It covers the configuration where the one host is embedded in the UICC which is connected to the host controller embedded in the Contactless front-end (CLF).

45fba

Technical specification that defines the remote management of files and applets on the SIM/USIM. It describes the APDU format for remote management.
