The mobile station (MS)[citation needed] comprises all user equipment and software needed for communication with a Wireless telephone network.
The mobile station refers to the mobile phone, i.e., the handset held by the users in the mobile network. This is the terminology of 2G systems like GSM. In the 3G systems, mobile station (MS) is now referred as user equipment (UE).
In GSM, the mobile station consists of four main components:
- Mobile Terminal (MT)- offers common functions that are used by all the service the mobile station offers. It is equivalent to the network termination of an ISDN access and is also the end-point of the radio interface.
- Terminal Equipment (TE) - is a peripheral device of the mobile station and offers services to the user. It does not contain any functions specific to GSM.
- Terminal Adapter (TA) - hides radio-specific characteristics.
- Subscriber Identity Module (SIM) - is a personalization of the mobile station and stores user specific parameters (such as mobile number, contacts etc).
