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 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 moreWhat are the components of GPRS?
All the databases involved in the network will require software upgrades to handle the new call models and functions introduced by GPRS.
Read moreWhat are the various types of interfaces that are provided with GPRS system architecture?
The GPRS element interfacing with the NSS is SGSN. The important interfaces to the NSS are the SGSN-HLR (Gr), SGSN-EIR (Gf), and SGSN-MSC/VLR (Gs) . The other interfaces are implemented through the intra-PLMN backbone network (Gn), the inter-PLMN backbone network (Gp), or the external networks (Gi).
Read moreWhat is GPRS interface explain?
Different network components of the GPRS are connected together by well defined interfaces . Some new interfaces to GSM have been added in GPRS to support packet switched data mainly between GGSNs, SGSNs and other network components.
Read moreIs GPRS a mobile communication protocol?
GPRS is also known as GSM-IP that is a Global-System Mobile Communications Internet Protocol as it keeps the users of this system online, allows to make voice calls, and access internet on-the-go.
Read moreWhat is GPRS protocol?
GPRS Tunnelling Protocol (GTP) is a group of IP-based communications protocols used to carry general packet radio service (GPRS) within GSM, UMTS, LTE and 5G NR radio networks . In 3GPP architectures, GTP and Proxy Mobile IPv6 based interfaces are specified on various interface points.
