What is the Gn interface?
‘Gn interface’ is the interface between the SGSNs and the GGSNs when they exist within the same mobile network. Gn Interface. Learn Mobile Packet Core Network in 5 Hours. Online Course. In case of roaming scenario, the user is traveling to another mobile network.
What is GN and GI?
Gn—The Gn interface is the connection between an SGSN (S-GW ) and a GGSN within the same public land mobile network (PLMN). Gi—The Gi interface is the connection between a GGSN and the Internet or destination networks connected to a PLMN.
What is the application layer protocol used for the S6a interface between MME and HSS?
UDP
UDP: This protocol transfers signalling messages between MME and SGW. UDP is defined in RFC 768. S6a interface between MME and HSS. It enables transfer of subscription and authentication data for authenticating/authorizing user access to the evolved system (AAA interface) between MME and HSS.
What is Gi interface in LTE?
The Gi Interface is a GPRS interface which is located between the GGSN (Gateway GPRS Support Node) and the external PDN (Public Data Network).
What is GB interface in telecom?
The Gb interface is a GPRS interface which is located between the SGSN (Serving GPRS Support Node) and the PCU (Packet Control Unit).
What is MME in 4G?
The mobility management entity (MME), which presents a key control node for the LTE access network, manages UE access network and mobility, as well as establishing the bearer path for UE’s.
What is the interface name between LTE and 5G GNB?
In LTE networks, X2 and S1 interface are defined as an interfaces between RAN nodes and between RAN and Core Network. 5G is expect to operate in two modes as non -standalone and standalone mode of operation.
What is the protocol stack for the GN / GP interface?
The protocol stack for Gn/Gp interface shows that it uses TCP/IP in the network packet routing between different nodes. While, it uses the GTP-U protocol ‘GPRS Tunneling Protocol’ in the application layer. GTP-U refers to ‘GPRS Tunneling Protocol for the user plane’, it tunnels user data between the SGSNs and the GGSNs in the user plan.
What is the interface between the MS and the GGSN?
Below diagram shows the interfaces exist between the MS and the GGSN in user plan in 2G network, The BSS means ‘Base Station Subsystem’. And it contains the BSC and the BTS. Learn Mobile Packet Core Network in 5 Hours. SGSNs and GGSNs use the ‘ Gn interface ‘ in the communication between each other.
Is the SGSN the same as the GGSN?
In case the SGSNs exist in different PLMN than the GGSNs, this interface name will be the ‘Gp interface’ The protocol stack for Gn/Gp interface shows that it uses TCP/IP in the network packet routing between different nodes.
