What is Rx interface 3GPP?
The Rx interface is used to exchange Flow Based Charging control information between the Charging Rules Function (CRF) and the Application Function (AF). As defined in the stage 2 specifications (3GPP TS 23.125 ), this information is used by the CRF for the Flow Based Charging (FBC) decisions.
What is Gx Gy interface?
The Gy interface is the online charging interface between the PCEF/GW (Charging Trigger Function (CTF)) and the Online Charging System (Charging-Data-Function (CDF)). The Gy interface makes use of the Active Charging Service (ACS) / Enhanced Charging Service (ECS) for real-time content-based charging of data services.
What is Sy interface?
The Diameter SY (DSY) Interface acts as the Sy reference point between an external Policy and Charging Rule Function (PCRF) and the OCS (Prepaid Charging). Features. The following Command Codes specified in 3GPP TS 29.219 V14.1.0 (2017-03) are supported: Command-Name.
What is the difference between Gx and Gy interface?
The Gy reference the interface between a PGW and an OCS. Gx references the interface between PCRF and PGW/PCEF .
What is VoLTE call flow?
Voice over LTE (VoLTE) is the standard for voice call setup in LTE networks. When VoLTE is deployed, phones will not need to fallback to 3G for voice calls. VoLTE uses IMS signaling to setup voice calls. An example of sending an SMS over IMS is also included. Sample RTP and RTCP messages are also shown in the flow.
What is interface diameter?
Diameter interfaces provide connections among Diameter nodes to enable essential service provider network functions such as authentication, online and offline billing, and policy and charging.
What is Interface diameter?
Which is the interface between PCRF and OCS?
dsTest supports the Diameter Sy interface on both the (client) Policy Charging and Rules Function (PCRF) and the (server) Online Charging System (OCS) in 3GPP LTE networks. Determine the impact of the transfer of information relating to subscriber spending on your PCRF or OCS.
Why is IMS needed?
IMS, or IP Multimedia Subsystem, is often touted as a must-have network evolution for mobile operators that want to derive value from future applications. The goal of IMS is to replace the operator’s current back-end network architecture with an all IP-based system making it easier to deploy applications.
What is the difference between IMS and VoLTE?
Quality of Service: the fundamental difference The fundamental difference of VoLTE compared to VoIP is that VoLTE requires a QoS component. While the VoLTE uses IMS and a separate radio frequency to help maintain the quality of the VoLTE transmission.
What is DIAMETER Sh interface?
Sh is a DIAMETER interface; having application ID 16777217, between Application Server (AS) and HSS. Application Server is place where actually the services are executed e.g. Call-Forwarding services related processing take place at Application server.
What is AAA DIAMETER?
The Diameter Protocol provides authentication, authorization, and accounting (AAA) messaging services for network access and data mobility applications in 3G, IP Multimedia Systems (IMS), and LTE/4G networks.
What can the GX interface application be 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.
Which is GX interface responsible for Offline charging?
After you are familiar with OFCS (Offline Charging System) and OCS (Online Charging System) time has come to be more up to date with interfaces that are being used to exchange signaling data. At first I will talk about Gx interface which is responsible for Offline Charging, but not only.
Which is test Serving Gateway ( SGW ) gxc or AGW GXA?
Test Serving Gateway (SGW) Gxc interfaces in LTE Evolved Packet Core (EPC) networks and Access Network Gateway (AGW) Gxa interfaces in trusted IP Connectivity Access Networks (IP-CAN) with our Policy Control and Charging Rules Function (PCRF) Emulator.
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.
