Radio Admission Control. The RAC function is located in the eNodeB and controls admission or rejection of new radio bearer establishment requests. The goal of RAC is to maximize radio resource utilization while ensuring that the required Quality of Service (QoS) is achieved for sessions which are already established. RAC can take into account the overall resource situation in E- UTRAN, the QoS requirements, the priority levels, the provided QoS of in- progress sessions and the QoS requirements of new radio bearer requests. See 3GPP TS36.300, Section 16.1.2.

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.

(Third Generation) The broadband telecommunications systems that combine high speed voice, data and multimedia.

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.

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.

Home Environment. The HE of a subscriber is responsible for the overall pro- vision and control of the personal service environment to the subscriber. 

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.
