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.

M2M
Machine-to-Machine. Technology enabling communication between machinesfor applications such as smart meters, mobile health solutions, etc.
MIM
Machine Identification Module. The equivalent of a SIM with specific features such that it can be used in machines to enable authentificationMMS (Multimedia Messaging Service) a standard way of sending messages that include multimedia content (e.g. photographs) to and from mobile phones.
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
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.

DL
DownLink. The radio link in the direction from the base station to the mobile terminal.

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.
