Gateway Link Set

A link set created on the SEAS interface that combines the functions of a gateway screening screen set. Like an EAGLE gateway screening screen set, a gateway link set defines the screening references that screen the messages on the link set. It also defines the link set whose messages are to be screened. A gateway link set can be configured only from a SEAS terminal and not from an EAGLE terminal.

Gateway Screening (GWS)

See GWS

Gateway Screening Redirect Function

A function in the EAGLE that redirects specified MSUs to a customized database. The EAGLE uses gateway screening to qualify incoming MSUs for redirection. Once gateway screening is passed, the original MSU is encapsulated into a new MSU and routed to its new destination.

G-Flex

GSM Flexible numbering

A feature that allows the operator to flexibly assign individual subscribers across multiple HLRs and route signaling messages, based on subscriber numbering, accordingly.

G-Flex MLR

G-Flex MAP Layer Routing

A feature that supports G-Flex routing for messages that is based on the MAP-layer IMSI and MSISDN parameters and that does not involve checking the format of the SCCP Called Party Address (CdPA), though the messages contain CdPA parameters in ITU E.214 format.

GGA

Get-Gateway-Answer

A reply to a GGR. It contains session information for the subscriber present in the GGR.GGA includes the bindings for the subscriber such as, Access Point Name, PCEF FQDN, and Creation timestamp. The session information is aggregated in the GGA based on the PCRF to which is it assigned.

GGR

Get-Gateway-Request

A request for information for either an IMSI or an MSISDN. Only one subscriber (IMSI or MSISDN) is allowed to be queried per GGR. The GGR is generated by the GQC.

GGSN

Gateway GPRS Support Node

An edge router that acts as a gateway between a GPRS wireless data network and other networks. The MPE supports GGSN nodes as network elements. See also GPRS, PGW, and SGW.

GHOST

GLA

Gateway Location Application A DSR Application that provides a Diameter interface to subscriber data stored in the DSR’s Policy Session Binding Repository (pSBR). Subscriber data concerning binding and session information is populated in the pSBR-B by the Policy Diameter Routing Agent (Policy DRA). GLA provides methods for a Diameter node to query binding information stored in the pSBR-B. The query can be by either IMSI or MSISDN. GLA processes Diameter Requests and generates Diameter Answers.

Contains the communications processor and applications processor and provides connections to the Interprocessor Message Transport (IMT) bus. The GPSM-II card can run on the OAM, IPS, or MCP applications.

This card runs various GPLs and applications in the EAGLE. As a control card, it runs the OAM application and EOAM GPL. Used when the legacy TDM card and MDAL card are used.

GTT

Global Title Translation

A feature of the signaling connection control part (SCCP) of the SS7 protocol that the EAGLE uses to determine which service database to send the query message when an MSU enters the EAGLE and more information is needed to route the MSU. These service databases also verify calling card numbers and credit card numbers. The service databases are identified in the SS7 network by a point code and a subsystem number.

GTT Actions Feature

Collectively, the GTT Action - DISCARD, GTT Action - DUPLICATE and GTT Action – FORWARD features.

GTT Action - DISCARD

A feature that causes the MSU to be discarded when a matched translation contains a "GTT Action - DISCARD" controlled GTT Action.

GTT Action - DUPLICATE

A feature that causes a copy of the MSU to be sent to the duplicate node, in addition to routing the translated MSU, when a matched translation contains the DUPLICATE GTT Action.

GTT Action – FORWARD

A feature that causes the translated MSU to be forwarded to another network entity, when a matched translation contains the FORWARD GTT Action.

GUI

Graphical User Interface

The term given to that set of items and facilities which provides you with a graphic means for manipulating screen data rather than being limited to character based commands.

GW

Gateway

A combination of hardware and software to connect disparate networks by means of protocol conversion. A gateway has the task of transferring messages from computer network to another, which requires communication protocols to be translated.

GWS

Gateway Screening

Used at gateway STPs to limit access into the network to authorized users. A gateway STP performs inter-network routing and gateway screening functions. GWS controls access to nonhome SS7 networks. Only an MSU that matches predefined criteria in the EAGLE database is allowed to enter the EAGLE.

Gx

The Diameter credit control based interface between a PCRF and a PCEF as defined by 3GPP. The interface is used to convey session information from the PCEF to the PCRF, and in reply the PCRF provides rule information for the PCEF to enforce.

Gx'

A vendor specific Gx like interface with minor variations as the protocol for DPI and PCRF communications before the standardized Sd reference point/protocol was available. Gx-Prime uses the same Application ID (16777238) as Gx does and the same command code set (Credit Control Request/Answer and Re-Auth Request/Answer) as well.
