The Function :
Base Transceiver Station(BTS)
A piece of network equipment that facilitates wireless communication between a device and network.
Consists of the following:
Antennas that relay radio messages
Transceivers
Duplexers
Amplifiers
Also known as a base station (BS), radio base station (RBS) or node B (eNB).

:Base Station Controller (BSC)
A critical mobile network component that controls one or more base transceiver stations (BTS)
Known as base stations or cell sites
To communicate with the MSC and data must be managed as information overflow, impacting MSC efficiency.
It eliminates MSC base station activity management requirements
It also allowing the MSC to handle critical tasks, such as traffic balancing and database management.

Mobile Switching Center (MSC)
The centerpiece of a network switching subsystem (NSS)
also performs a host of other duties, including routing SMS messages, conference calls, fax, and service billing as well as interfacing with other networks, such as the public switched telephone network (PSTN).
Mostly associated with communications switching functions, such as call set-up, release, and routing.
The MSC is structured so that base stations connect to it, while it connects to the PSTN.
Whether between two cell phones or between a cell phone and a landline telephone, travel through the MSC

A call for a mobile subscriber comes from outside the mobile network.
Make a call to somebody outside the mobile network the call is routed through the GMSC.
