•  Base station controller (BSC)  
•  Base transceiver station (BTS) 

The BSC provides all the control functions and physical links 

between the mobile switching center (MSC) and BTS. BSC 

is a high-capacity switch that provides capabilities such as 

handover, cell configuration data, and control of radio 

frequency (RF) power levels in BTSs. In an area, the BTS 

connects to the BSC through the Abis interface. 

           

The BSC 500i is a table-top equipment. It draws power from 

the battery as it is deployed in exchanges. 

The BTS is the radio equipment (transceivers and antennas) 

that provides radio access to the mobile stations. It is 

required to service each cell in a network. BSS controls a 

group of BTSs. 

You can configure and monitor BTS and BSC elements in a 

network by using operations management center (OMC).

 OMC can operate all nodes of the BSS, transmission, 

and power system. The OMC is a functional entity from 

where the network operator monitors and controls the BSS. 

The purpose of OMC is to offer a cost-effective support for 

centralized, regional, local operational, and maintenance 

activities that are required for a GSM network.  

Each network element supports or implements one or more 

network management functions used by OMC.
