UE (WIRELESS TELEPHONE)

In the Universal Mobile Telecommunications System (UMTS), 'user equipment' ('UE') is any device used directly by an end user to communicate. It can be a hand-held telephone, a card in a laptop computer, or other device. It connects to the base station ("Node-B", or 3G Base Transceiver Station) as specified in the 25-series of specifications. It roughly corresponds to the mobile station in GSM systems.
Radio interface between the UE and the Node-B is called ''Uu''.

UE handles the following tasks towards the core network:

★ Mobility management

★ Call control

★ Session management

★ Identity management
The corresponding protocols are transmitted transparently via a Node-B, that is, Node-B does not change, use or understand the information. These protocols are also referred to as ''Non-access stratum'' protocols.
