wirelessly through radio frequency to the service provider. Mobile network
allow number of uses such as voice calls, messaging and internet data.
Most common technology system deployed by cellular network
is Global System for Mobile Communication or GSMGSM Overview: Mobile network devices are connected wirelessly to at least
one transceiver called the Base Transceiver Station(BTS) which offer services
provided by it’s technology(2G/3G)The transceiver is connected wirelessly or through wire to a
Base Station Controller which controls and provides intelligent management of
resources for hundreds of BTS.BSC also acts as the gateway connecting to the
core two networks of the mobile operator. Mobile Switching Center is the primary node responsible for
providing voice and SMS services connecting to the public switching telephone network
(PSTN). MSC handles opening and terminating end to end connections between
voice calls and SMS.VLR is database that contain the exact location of the
devices connected to the network at present. It is an integral part of the MSC
as it enables end to end connections to be made.HLR is the database that contain subscriber information of
networkSGSN is a support system for the main GGSN system for
handling data connections. SGSN handles routing to BSC and BTS, authenticating
and security ect. GGSN is the main gateway for connecting to the Internet for
GSM systems. GGSN converts the GPRS data coming from the mobile devices to the
relevant Internet Protocols and vice versa.CvBS is the billing system that work in parallel connected
