UE (wireless telephone)

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 any 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".

Functionality

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.
