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 the Sy interface?
What is Diameter 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). This section illustrates the architecture involved to facilitate the Sy Reference Point functionality.
What is Telecom diameter?
Diameter is an authentication, authorization, and accounting protocol for computer networks. It evolved from the earlier RADIUS protocol. Diameter Applications extend the base protocol by adding new commands and/or attributes, such as those for use with the Extensible Authentication Protocol (EAP).
What is Pcrf in telecom?
Policy and Charging Rules Function (PCRF) is the software node designated in real-time to determine policy rules in a multimedia network. As a policy tool, the PCRF plays a central role in next-generation networks.
What is GX traffic?
The Gx reference point is used for provisioning and removal of 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.
What is n40 interface in 5G?
n40 is a frequency band designated by the 5G NR standard. When the NR band is overlapping with the 4G LTE band, they share the same band number.
What is Sh interface?
The IMS specification defines the Sh interface as the method of communication between the Application Server (AS) function and the Home Subscriber Server (HSS), or between multiple IMS Application Servers. The AS uses the Sh interface in two basic ways: To query or update a user’s data stored on the HSS.
What is the use of the GX interface?
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 the use of SSE gateway in LTE?

What are the key interfaces for LTE control?
Key Interfaces for LTE Control includes S1MME , S5/S8 , S10 , S11 , S6a , Gx , Gy , X2 , SGs S6 links connect MME to HSS.
What is the use of SGI interface in LTE?
SGi : This SGi interface is used between PGw towards internet or IMS Network . This is highway for Exit traffic from LTE Network SGs : The SGs interface is used for connectivity between LTE MME to 2G (GERAN) / 3G (UTRAN) MSCs .
