Iu-PS is the interface between the UMTS RNC (Radio Network Controller) and the SGSN (Serving GPRS Support Node) supporting UMTS integrated services such as multimedia and global roaming to mobile users.
Read moreWhat is the interface between UTRAN and CN?
There are four interfaces connecting the UTRAN internally or externally to other functional entities: Iu, Uu, Iub and Iur . The Iu interface is an external interface that connects the RNC to the Core Network (CN). The Uu is also external, connecting Node B with the User Equipment (UE).
Read moreWhat is the role of SGSN and GGSN components?
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 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 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.
