Mobile network technologies GSM/GPRS/UMTS/LTE


mobile network technologies has evolved
over time to satisfy the increasing customer needs for higher data rates and
better services in brief the mobile station you are having should be able to
make voice calls in addition to data sessions the voice calls in the mobile
network are using the circuit switching CS domain while the data sessions are
using the packet switching PS domain understand different mobile network
technologies let’s take a quick overview on the organization that developed those
technologies 3gpp is the organization that manages and develops mobile network
standards those standards cover all aspects of mobile networks in 1997 3gpp introduced release 96 of
the standards in this release the GSM technology existed gsm had only a CS
domain that passed voice calls while it didn’t support data sessions
therefore in 1998 3gpp introduced release 97 of the standards in which
network architecture enhanced to support data sessions this is done by
introducing GPRS general packet radio service which contains a PS domain to
pass data sessions to sum up the core network describes the combination of the
CS domain and the PS domain and mobile network the mobile station connects to
the core network through the access network which controls the communication
between the mobile station and the core network the access network name and GPRS
is GERAN which refers to GSM edge radio access network in fact this whole
network that contains the access network and the core network forms the second
generation network or 2G network in order to afford higher data rates and
better utilization for network resources 3gpp introduced release 99 of the
standards and this was in year 2000 in this release the third generation 3G
network existed UMTS universal mobile telecommunication system in fact this is
the term used as an umbrella for the third generation technologies UMTS is
having both a CS domain for voice calls in addition to a PS domain for data
sessions the core network of UMTS is inherited from GSM/GPRS Network actually
the access network for the 3G network is the UTRAN which refers to universal
terrestrial radio access network in fact GPRS afforded PS service to
mobile networks therefore you may find it mentioned in
two different manners first GPRS along with UMTS this means GPRS refers to 2G network while UMTS refers to 3G network second GPRS alone in this case
GPRS refers to PS service in both 2G and 3G networks this is because the core
network in UMTS is inherited from GSM/GPRS network after that 3gpp introduced release eight in year 2008 in this release long-term evolution LTE
existed it is the fourth generation 4G network
unlike previous generations LTE network is having only a PS domain in the core
network while it doesn’t have a CS domain for voice calls the mobile
station can make voice calls by connecting to an external network which
is the IMS network the mobile station connects to the IMS network through the
PS domain in addition the PS domain architecture enhanced and named the
evolved packet core EPC the access side of the LTE network is the E-UTRAN
which refers to Evolved UTRAN in later 3gpp standards release 14 and 15 3gpp
introduced new technologies like Internet of Things IOT and fifth
generation 5G network mobile networks evolved over time to
afford better services first came the 2g network which is the GSM/GPRS
architecture which contains a CS domain for voice calls and a PS domain for data
sessions then came the third generation network UMTS UMTS inherited its core
from the GSM/GPRS architecture therefore GPRS term can be used to call the PS
domain in both 2G and 3G networks after that came the 4G network which is the
LTE the LTE network contains only a PS domain which is the evolved packet core
EPC
