What is Gx and Gy interface?
Gx interface enables signaling of PCC decisions, negotiation of IP-CAN bearer establishment mode and termination of Gx session . Gy. It is online charging reference point. Gy lies between PCEF (Policy Control Enforcement Function) and OCS (Online Charging Function).
What is Gx interface in LTE?
Gx. Interface between the PGW and the Policy and Charging Rules Function (PCRF). In particular, this is the interface between the Policy Control Enforcement Function (PCEF) or the PGW and the PCRF. OAM. Operational and maintenance interface, used to manage the device.
What is GX protocol?
Gx Protocol The Gx application is defined as a vendor specific Diameter application, where the vendor is 3GPP and the Application-ID for Gx application is 16777238. The vendor identifier assigned to 3GPP by IANA is 10415. Gx-specific AVPs defined in 3GPP Gx specification TS 29.212.
What is the difference between PCEF and PCRF?
PCEF system is part of PCRF which is shown in the figure-1 and figure-2. PCEF is situated inside PDN GW (Packet Data Network Gateway) or in short PGW. The major difference between PCRF and PCEF is that PCEF does support offline and online charging interactions while PCRF does not support these.
What is Gx interface used for?
The Gx Interface application can be used to simulate PGWs or GGSNs to test the PCRF. The Gx Interface application allows users to validate PCRF performance and capacity in a realistic network environment, replicating the deployment configuration.
What is GA interface?
The Ga interface is a GPRS interface which is located between the GSN (GPRS Support Nodes) and CGF (Charging Gateway Function).
What is Gy interface?
In wireless applications, the Gy interface is a 4G interface between the PCEF and OCS.
What is GPRS CDR?
A database record unit used to create billing records. When applied to GPRS , CDR are generated typically by the SGSN (Serving GPRS Support Node) and GGSN (Gateway GPRS Support Node), recording data volumes and QoS (Quality of Service) rather than call time. …
What is Gy call?
Gy is between Online Charging System (OCS) and PCEF. In most cases PCEF is based inside PDN GW (Packed Data Network Gateway) or just short PGW. Gy interface allows online credit control for service data flow based charging.
What is Gy application?
Credit Control (Gy//Ro) Application ( 4 ) The Gy interface is used for online charging between the OCS and the PDN Gateway (PGW), while the Ro interface is between the OCS and the IMS Call Session Control Function (CSCF). The two interfaces are functionally equivalent.
What is 4G HSS?
Home Subscriber Server. The HSS is the master database for a given subscriber, acting as a central repository of information for network nodes. Subscriber related information held by the HSS includes user identification, security, location and subscription profile. The HSS is a functional element of LTE and IMS.
What do you need to know about the GX interface?
The Gx Interface application allows users to validate PCRF performance and capacity in a realistic network environment, replicating the deployment configuration. Execute timed chains of test events with a run-time command or during an automated test to trigger client-initiated procedures.
Where is the reference point for GX located?
The Gx reference point is located between the Policy Control and Charging Rules Function (PCRF) and the Policy and Charging Enforcement Function (PCEF).
Which is the best emulator for the GX interface?
The PCRF Emulator provides policy and charging control services for the Gx interface—all of the functionality required by a PGW (PCEF) or a GGSN.
When to use the GX interface between PCRF and PCEF?
The Gx reference point is used for provisioning and removal of Policy and Charging Control (PCC) rules from the PCRF to the PCEF and the transmission of traffic plane events from the PCEF to the PCRF. The Gx reference point can be used for charging control, policy control or both by applying AVPs relevant to the application.
