The Gy interface in telecommunications is a Diameter-based protocol that connects the Policy and Charging Enforcement Function (PCEF) and the Online Charging System (OCS).

Here's a brief overview of its functions:

  • Charging Control: Gy is responsible for real-time charging of user sessions, allowing the OCS to rate the data usage as it occurs.
  • Policy Control: The PCEF uses the Gy interface to request charging authorization from the OCS for data services and to report session termination.
  • Rating and Billing: The OCS uses information from PCEF over Gy to determine charges for the services rendered, which can be based on the volume of data, time of usage, or other service-related attributes.
  • Real-Time Credit Control: Gy facilitates real-time credit checks and ensures that users do not exceed their credit limits.
