What is GI SGi interface?
the Gi/SGi interface is where the GPRS/lte network connects to the Internet and corporate networks.
What is SGi interface in LTE?
The importance of the SGi (3G/LTE) and N6 (5G) interfaces. The SGi interface is defined by the 3GPP as the interface between the Evolved Packet Core (EPC) and the Public IP network. Importantly, traffic through the interface can be identified by user IP, making user and service differentiation a reality.
What is SGi in networking?
SGI (Silicon Graphics) is a leading manufacturer of high-performance computing, data management, and visualization products. SGI recently announced a new technology called Visual Area Networking that allows users to interact with advanced visualization programs from any device over standard networks.
What is Gi interface?
Gi—The Gi interface is the connection between a GGSN and the Internet or destination networks connected to a PLMN. SGi – The SGi interface is the connection between a P-GW and the Internet or destination networks connected to a PLMN in 4G networks.
What is S11 interface?
S11 – This is the interface between the MME and S-GW in an LTE network. The interface is based on Gn/GTP-Control (GTP-C) (interface between SGSN-GGSN) with some additional functions for paging coordination, mobility compared to the legacy Gn/GTP-C (SGSN-GGSN) interface. S11 is a many-to-many interface.
What is Gx interface?
The Gx interface is a 4G interface between the PCEF and PCRF.
What is X2 interface in LTE?
The X2 is the interconnecting interface between two eNodeBs in LTE network and supports both Control Plane and User Plane. The principle Control Plane protocol is X2-AP (X2 Application Protocol) resides on SCTP (Stream Control Transmission Protocol).
What is MME and HSS?
The MME is the key control-node for the LTE access-network. It is responsible for idle mode User Equipment (UE) paging and tagging procedure including retransmissions. The MME also terminates the S6a interface towards the HSS for roaming UEs.
What is N3 interface in 5G?
The 5G N3 interface performs the role of conveying user data from the RAN to the User Plane Function, making it possible to create both low- and high-latency services. It replaces the S1-U interface from the 4G EPC and is key for supporting the new CUPS architecture, with distributed user data processing.
What is GI DNS?
Gi is external facing and Gn is internal network for telco operation point of view. These are 3gpp interface names. For network they carry user plane/control plane traffic. You can use bind for Gn /Gi purpose but keep separate each other. make sure proper security is enabled on both DNS servers.
What is S1 mode in LTE?
LTE S1-UP (user plane) The S1 user plane external interface (S1-U) is defined between the LTE eNodeB and the LTE S-GW. The S1-U interface provides non guaranteed data delivery of LTE user plane Protocol Data Units (PDUs) between the eNodeB and the S-GW. Transport network layer is built on IP transport and GTP-U.
What is S11 in LTE?
What is the use of SGI in PDN?
SGi:- It is the reference point between the PDN GW and the packet data network. Packet data network may be an operator external public or private packet data network or an intra operator packet data network, e.g. for provision of IMS services. This reference point corresponds to Gi for 3GPP accesses.
What is LTE interface in LTE?
This LTE interface lies between HSS and SGSN (i.e. Serving GPRS Support Node). It is similar to S6a interface. It lies between H-PCRF and V-PCRF in EPS network.
What is the difference between S13 and SGI?
S13:- It enables UE identity check procedure between MME and EIR. SGi:- It is the reference point between the PDN GW and the packet data network. Packet data network may be an operator external public or private packet data network or an intra operator packet data network, e.g. for provision of IMS services.
What is S6C interface in LTE?
S6c interface is used for mobility related authentications. It takes care of transport of commands to retrieve and to store mobility parameters. This LTE interface lies between HSS and SGSN (i.e. Serving GPRS Support Node). It is similar to S6a interface.
