How Cellular Network Works?

Networks are called cellular because of having numerous cells. The areas that have cellular base station are often called as BS (base station). When cellular phones detect the address of nearest base station then they will start to build a connection. This process of building up connection to the base station is called Registration. So, cellular phones are called Mobile Subscribing Unit (MSU) or say simply mobile. The base stations are the collection and combination of antennas, amplifiers, receivers, transmitters and hardware and software for propagating and retrieving signals and converting Radio Frequency (RF) way to audio voice signals and vice versa. The base station contains some sort of uplinks that transmit the signals back and forth from cellular Mobile Switching Centre (MSC). These uplinks transmit and receive signals over microwave links at the speed of 1.544 mbps. We can call MSC as the processor of cellular networks which go in the search of the required destination and passes from so many steps that are required in order to make call such as Authentication code (AuC). AuC it checks that either you have balance in your account to call or not then it will respond accordingly. The cellular network has enormous MSCs with clumps and cluster of base stations; these centers are called Mobile telephone Switching Office (MTSO) and Mobile Telephone exchange (MTX)

MSC routes all the calls through the cluster of cell and issue instruction to Base station. These Base stations are connected to database which contain information about cell phone subscriber. MSC helps to search particular geographical area where from the phones calls are connected and forwarded to destination. It also helps in tracking the phone number of obnoxious call. MSC routes all calls to Gateway Mobile Switching Center (GMSC) which takes calls from all MSCs and route them to final destination. Now here is the case for special concern that when the number is asked for the roaming then those numbers are directly connected to MSC. MSC sent them to GMSC and GMSC finally sent to Base station (BS)
