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 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).
