Global System for Mobile Communications or as it was originally known as "Group Special Mobile" is a network composed of many sections or functional entities. These functions and the interactions between them is the GSM network. A GSM network is made up of three parts. A GSM phone that's carried by every subscriber is a Mobile Station. The mobile station keeps in constant contact with the Base Station Subsystem. The maximum range that the Mobile and the Base Station can communicate is about 22 miles. The third and the main part of this system is the Mobile services Switching center (MSC). The MSC does the switching of calls and also connects mobiles to fixed line networks. The communication between the mobile and Base Station Subsystem is done in "Um" interface and between Base Station Subsystem and MSC, by using "A" interface.
