What is Application ID of Gy interface?

Gy is another diameter interface between PCEF and OCS having application id 14 for a charging application.

What is the difference between Gx and Gy?

Gx interface enables signaling of PCC decisions, negotiation of IP-CAN bearer establishment mode and termination of Gx session . It is online charging reference point. Gy lies between PCEF (Policy Control Enforcement Function) and OCS (Online Charging Function).

What is Gy interface in telecom?

In wireless applications, the Gy interface is a 4G interface between the PCEF and OCS.

What is Gx interface?

The Gx interface connects the PCRF with policy enforcement points. These are found in the packet core of 3G and 4G networks. The serving GPRS support node (SGSN), gateway GPRS support node (GGSN), and PDN Gateway are all considered as enforcement points, supported by the Gx interface.

What is Gy and Sy?

The Sy references the interface between PCRF and the OCS. The Gy reference the interface between a PGW and an OCS. Gx references the interface between PCRF and PGW/PCEF .

What is GX in LTE?

(i) Gx Interface – PCRF Server supports the Gx interface as defined in 3GPP Release 7, 8, 9 and 10. It is used for provisioning service data flow based on charging rules. It is located between the PCRF and the Policy and Charging Enforcement Function (PCEF).

What is GZ interface?

The Gz interface is between the OCS and the PDN Gateway (PGW) and the Rf interface is between the OCS and the IMS Call Session Control Function (CSCF). The two interfaces are functionally equivalent.

What is GX in Diameter?

Gx Diameter Interface in ISG Gx reference point is used to provision, modify and remove rules for policy and charging control from the PCRF to the PCEF. The policies downloaded are installed on the ISG session and any monitoring events installed is detected and notified to PCRF.

What is OCS quota?

Quota consumption, used by the OCS, indicates to the client that the quota consumption must be stopped after a period at session termination or when no packets are received. Time quota threshold indicates the threshold in seconds when the granted quota is time.

What is PCEF Gy interface?

Gy is another diameter interface between PCEF and OCS having application id 14 for a charging application. So first we will understand what is PCEF and OCS. PCEF’s full form is Policy and Charging Enforcement Function. This component is located inside GGSN or PGW. Gy interface is for online charging.

How do I identify a problem in the GY interface?

We first need to identify at which layer in the Protocol the problem exists.The identification steps are: • First we need to check at which layer the problem exists. Activate the tracing instance of Gy interface to see if any messages are seen. If no message is seen, then this means that the Diameter Credit Control Application layer is not set up.

What is the Huawei Gy interface?

PREAMBLE: Gy interface is an interface between the Gateway GPRS Support Node (GGSN) /Packet Data Network – Gateway (PDN-GW) and the Online Charging System (OCS). A Case Study involving the Huawei UGW V9R13 (The UGW is Huawei’s Combined GGSN for 2G/3G & PDN-GW for 4G in my case).

What is the charging application specification for Gy?

The charging application specification is given in diameter standard 4006 . The following section describes call flow GTP and Diameter messages for charging over the Gy interface. Gy uses two messages over Diameter protocol, Credit control request (CCR), and Credit Control Answer (CCA).
