What is meant by GGSN?
The Gateway GPRS Support Node, abbreviated as GGSN, is a node acting as an extension for the SGSN (see description for MSC) in GPRS networks to connect a GPRS network to an external data network (e.g., Internet).
What is GGSN in 5g?
The Gateway GPRS Support Node (GGSN) is a main component of the GPRS network. The GGSN is responsible for the interworking between the GPRS network and external packet switched networks, like the Internet and X. 25 networks.
What is 3G GGSN?
A Gateway GPRS Support Node (GGSN) is part of the core network that connects GSM-based 3G networks to the Internet. The GGSN, sometimes known as a wireless router, works in tandem with the Serving GPRS Support Node (SGSN) to keep mobile users connected to the Internet and IP-based applications.
What is the interface between SGSN and GGSN Gateway GPRS Serving Node?
IP based interface between internal SGSN and external GGSNs. Between the SGSN and the external GGSN, there is the border gateway (which is essentially a firewall). Also uses the GTP Protocol. Interface between the SGSN and the HLR.
What is the role of SGSN and GGSN components?
In GSM architecture we can only transport the voice signal. But if signal consists of the data then only GSM architecture cannot use. For that there are two more software components are used, SGSN (Serving GPRS supporting Node) and GGSN (Gateway GPRS supporting Node).
What is role of SGSN GR GGSN component?
The internal backbone is an IP based network used to carry packets between different GSNs. Tunnelling is used between SGSNs and GGSNs, so the internal backbone does not need any information about domains outside the GPRS network.
What protocol is used between SGSN and GGSN?
GPRS Tunneling Protocol (GTP)
The protocol used for the tunnel between the SGSN and GGSN is the GPRS Tunneling Protocol (GTP).
Why is tunneling needed between the GGSN and SGSN?
In order to reduce the load of passing the user plan data by the SGSN, the SGSN may decide to establish direct tunneling between the RNC and the GGSN.
What is a GPRS network What 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.
What are advantages of SGSN and GGSN?
Is PGW and GGSN same?
P-GW—In 2G and 3G networks, the node that handled all user packets to and from the user equipment is called the GGSN. In the LTE architecture, this is the Packet Gateway (P-GW) or sometimes seen as the Packet Data Network Gateway (PDN-GW).
What is PGW in network?
PGW (Packet Data Network Gateway) The Packet Data Network Gateway (PDN Gateway, also PGW) provides connectivity from the User Equipment (UE) to external packet data networks (PDNs) by being its point of exit and entry of traffic.
What is the interface between GGSN and ISP?
Gp interface is defined between two GSNs of different PLMN for exchanging the user profile and other signaling information between a SGSN and GGSN of another area. Gf interface is used between SGSN and EIR to query the IMEI information if a MS tries to register with the network.
What is the interface between SGSN and GGSN in a GPRS network Mcq?
15) What is the interface between GGSN and HLR in a GPRS network? Explanation: GGSN may also enquire HLR using SGSN. SGSN interfaces with HLR using Gr interface.
What is the interface between SGSN and MME?
S3 interface between SGSN and MME. It enables user and bearer information exchange for inter 3GPP access network mobility in idle and/or active state. UDP (User Datagram Protocol): This protocol signaling messages. UDP is defined in RFC 768.
