GGSN in Telecom
GGSN stands for "Gateway GPRS Support Node". It is a key component in the 2G/3G mobile network architecture.
It serves as the gateway between the mobile network and external packet data networks, as it receives and forwards data packets between the mobile network and the external packet data networks.
Also it assigns and manages IP addresses for mobile devices connected to the mobile network.
In addition, it applies the appropriate QoS and charging parameters based on the subscriber's profile and service requirements.

SGSN, GGSN – 2G/3G Network Architecture and Interfaces
2G/3G Network Nodes The following graph shows the 2G/3G Network Architecture. It includes the SGSN, GGSN, HLR, CG, PDN, RNC, and BSC. SGSN GGSN, HLR, CG, PDN, RNC, BSC, 2G/3G Network Interfaces Now we know the nodes that exist in the 2G/3G network. Let's learn the interface names that exist between those nodes. Every interface…

How SGSN selects the GGSN in GPRS, using iDNS and eDNS
The network is not having only one GGSN, it may have a few GGSNs. Also, it is having a lot of APNs. Some of those APNs exist on all GGSNs, and some exist only on one of the GGSNs. Therefore, GGSN selection mechanism have to exist, in order for the SGSN to be able to…

(MS-SGSN-GGSN) GPRS Interfaces in 3G network
Here, we illustrate the GPRS interfaces between the MS, the SGSN, and the GGSN in 3G network in both 'control plane', and 'data plane'. The 'control plane' is where the signaling messages are passing. While the 'data plane' is where user data is passing. User Plane interfacesin 3G Below diagram shows the interfaces exist between…
