What is Gb interface?

What is Gb interface?

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 GPRS protocol stack?

GTP is the protocol used between the SGSN and GGSN using the Gn interface. This is a Layer 3 tunneling protocol. The process that takes place in the application looks like a normal IP sub-network for the users both inside and outside the network.

What is GPRS Gb?

Overview. GPRS, or General Packet Radio Service, was introduced (in the late 90’s and early 2000’s) to enhance data carrying capabilities of the basic GSM Network. MAPS™ GPRS Gb supports simulation of BSS (Base Station Subsystem) and the SGSN (Serving GPRS Support Node) network elements over IP transmission protocol.

What is a interface in GSM?

GSM network interfaces list. A interface The A interface is used to provide communication between the BSS and the MSC. The interface carries information to enable the channels, timeslots and the like to be allocated to the mobile equipments being serviced by the BSSs.

What is Abis interface in GSM?

The interface within the GSM architecture, between the BTS (Base Transceiver Station) and BSC (Base Station Controller). This interface is usually configured using a 16Kbps slot structure.

Is GPRS a protocol?

GPRS Tunnelling Protocol (GTP) is a group of IP-based communications protocols used to carry general packet radio service (GPRS) within GSM, UMTS and LTE networks. In 3GPP architectures, GTP and Proxy Mobile IPv6 based interfaces are specified on various interface points.

What is Bssgp protocol?

BSSGP is a protocol used in the GPRS mobile packet data system. It denotes Base Station System GPRS Protocol. It transfers information between two GPRS entities SGSN and BSS over a BSSGP Virtual Connection (BVC).

What is Gn interface in LTE?

Gn interface which was being used in UMTS for the connectivity of SGSN and GGSN will be used in the initial stage of LTE between SGSN and P-GW but this interface will finally get replaced by S3 and S4 interfaces after the software up-gradation of SGSN. …

What is the protocol stack for the GB interface?

The Gb interface is an interface in the GPRS network between the SGSN and the BSS based on the connection-oriented Frame Relay protocol. The protocol stack currently comprises an L1 physical layer (related to Frame Relay), a Network Service (NS) layer, and a Base Station System GPRS Protocol (BSSGP) layer.

How does the GB interface work using IP?

The Gb interface between the BSS and the SGSN is modified to operate using the Internet Protocol (IP), and the BSS and the SGSN are configured to run on IP. Whenever a new Network Service Entity (NSE) is added to an existing BSS, or a new BSS Network Service (NS′)-Reset message to the SGSN requesting an NSEI.

What does the GB interface do for BSS?

The Gb interface connects the BSS and the SGSN. It allows for the exchange of signaling information and user data.

Where is the GB interface in GPRS network?

Figure 6.1 shows the position of the Gb interface within the GPRS network. The Gb interface is located between the BSS and the SGSN (between the gray boxes in Figure 6.1). It allows for the exchange of signaling information and user data, and the multiplexing of many users on the same physical resource.
