What is Gy?

Gy is a 3GPP reference point that defines the online charging protocol (OCP) between a charging trigger function (CTF) and an online charging system (OCS). It is primarily used in mobile networks to enable real-time charging for services based on usage, such as data volume or session duration. It allows operators to control service usage and prevent users from exceeding their credit limits.

Gy Complementary Technologies

Gx is a protocol used for policy and charging control. It is complementary to Gy, which is used for online charging. Gx is used between the Policy and Charging Rules Function (PCRF) and the Policy and Charging Enforcement Function (PCEF), while Gy is used between the PCEF and the Online Charging System (OCS).

Diameter

Diameter is a base protocol used by Gy. Gy is an application of the Diameter protocol suite. Therefore, Diameter is considered complementary as Gy is built upon it.

PCRF

The Policy and Charging Rules Function (PCRF) interacts with the Online Charging System (OCS) via the Gy interface. It provides policy rules that influence charging decisions. Therefore, it is complementary.
