Module
The unit formed of a chip and a contact plate.
UTRAN
Universal Terrestrial Radio Access Network. UTRAN consists of Radio Network Controllers (RNCs) and NodeBs of a UMTS network. It allows connectivity between the UE and the core network.
UICC
A high capacity smart card used in mobile terminals for GSM, UMTS/3G and now 4G/LTE networks.

USIM
Universal Subscriber Identity Module. A SIM with adbanced software that ensures continuity when migrating to 3G services.
HTTP
Hyper Text Transfer Protocol. A client-server communication protocol developed for World Wide Web. See IETF RFC2616, www.ietf.org.
UTRA
Universal Terrestrial Radio Access. The radio access solution for UMTS.
SIM
A subscriber identity module or subscriber identification module (SIM) is an integrated circuit chip that is intended to securely store the international mobile subscriber identity (IMSI) number and its related key, which are used to identify and authenticate subscribers on mobile telephony devices.

GSM
Global System for Mobile Communications. A European standard for digital cellular phones that has now been widely adopted throughout the world.
BER
Bit Error Rate. A measure of received signal quality, the proportion of received bits which is decoded erroneously.

IMS
Internet Protocol Multimedia Subsystem. An architectural framework for delivering Internet Protocol (IP) multimedia services via UTRAN and E- UTRAN. See 3GPP TS23.228 and TS23.406.
NDS
Network Domain Security. A security architecture for network domain Internet Protocol (IP) based control planes, which is applied to NDS/IP-networks (i.e. 3GPP and fixed broadband networks) to provide security in the Core Network (CN). See 3GPP TS33.210.
RAN
Radio Access Network. A RAN consists of the ground-based infrastructure required for delivery of communication between UEs and the Core Network (CN). In LTE, the RAN consists of one or more base stations (i.e. eNodeBs). Examples of other RANs are UMTS, TD-SCDMA, GSM, CDMA2000 and WiMAX.
RAT
Radio Access Technology. The RAT is the type of radio technology used in a Radio Access Network (RAN) to access the Core Network (CN), e.g. UMTS, GSM, CDMA2000, WiMAX.
3G
(Third Generation) The broadband telecommunications systems that combine high speed voice, data and multimedia.

IM
Using text on a mobile handset to communicate in real time
IP
Internet Protocol. A protocol for communicating data accross a network

OS
Operating System. Software that runs on computers and other smart devices and that manages the way they function.
SE
Secure Element. A secure and personalised physical component added to a system to manage users rights and to host secure apps. SE typically consist of a Silicon Chip, a secure Operating System, application software and a secure protocol to communicate to the device. SE can be a removable device (such as UICC or µSD for mobile devices or MIM for M2M connected machines). SE can also be components inside the system.
BS
Base Station. The entity in a radio access network responsible for radio trans- mission and reception in one or more cells to and from the UE. In LTE the BS is known as the eNodeB.

HE
Home Environment. The HE of a subscriber is responsible for the overall pro- vision and control of the personal service environment to the subscriber.Â
HO
HandOver. HO is a procedure by which a mobile terminal changes serving cells (within the same frequency or on different frequencies or even on different Radio Access Technologies (RAT)). See 3GPP TS36.133.
PS
Packet Switched. In PS communication each data packet is labelled with the destination address and routed over a shared transmission resource. In contrast with Circuit Switching (CS) where dedicated transmission resources are re- served between network nodes to deliver a reliable transmission rate and delay, in a PS connection the transmission rate and delay may vary depending on the traffic load and the medium capacity, with packets being buffered if necessary.
UE
User Equipment. The mobile unit which allows a user to access network services, connecting to the UTRAN or E-UTRAN via the radio interface. A UE can be subdivided into a Universal Integrated Circuit Card (UICC) and a Mo- bile Equipment (ME). See 3GPP TS21.905 Section 3.
UICC
A high capacity smart card used in mobile terminals for GSM, UMTS/3G and now 4G/LTE networks.
