After signal comes to SGSN, it delivers the data packet to the GGSN . GGSN routes the data packet to the data network (PDN- Predefined Data Network). Task of GGSN : Mediator between GPRS between backbone and external data networks.1 Haz 2021
Read moreWhat are advantages of SGSN and GGSN?
SGSN helps in the services within a network , whereas GGSN helps in the gateway outside the network. Also, the Packet Control Unit or PCU is present in the network that helps to determine where the data should be routed. It is either given to packet-switched or circuit-switched networks in the system. 3.
Read moreWhat is GGSN in UMTS?
The Gateway GPRS Support Node (GGSN) is the central element within the UMTS packet switched network . It handles inter-working between the UMTS packet switched network and external packet switched networks, and can be considered as a very sophisticated router.
Read moreWhat is GGSN and SGSN?
The gateway GPRS support node (GGSN) converts the incoming data traffic coming from the mobile users through the Service gateway GPRS support node (SGSN) and forwards it to the relevant network, and vice versa. The GGSN and the SGSN together form the GPRS support nodes (GSN) .
Read moreHow can I differentiate between SGSN and GGSN?
SGSN and GGSN are used for connecting our cell phones to mobile internet through GPRS, EDGE, HSPA and HSPA+ technologies in 2G GSM and 3G UMTS networks. SGSN is the main node that performs packet-switching functions, whereas GGSN is more of a router that connects SGSN to the external data networks .17 Kas 2019
Read moreWhat is the architecture of 2G?
The infrastructure of 2G and 3G cellular networks are similar. They comprise an air interface between the user’s mobile device and the base station and two core networks; one for circuit-switched voice and another for packet-switched data .
Read moreWhat is UMTS architecture?
UMTS system uses the same core network as the GPRS and uses entirely new radio interface . The new radio network in UMTS is called UTRAN (UMTS Terrestrial Radio Access Network) and is connected to the core network (CN) of GPRS via Iu interface.
