What is the function of PCRF in LTE?

The PCRF provides the QoS authorization (QoS class identifier [QCI] and bit rates) that decides how a certain data flow will be treated in the PCEF and ensures that this is in accordance with the user’s subscription profile. PCRF provides service management and control of the 4G service.

What is policy and charging control?

Policy and Charging Control (PCC) is an evolving technology and is seeing itself placed on top of the Business Support System (BSS) stack. It enables network controls that form the building blocks for new data and data-enabled products and helps operators make and collect money in real-time.

What is PCRF in IMS?

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.

Where is the policy charging and enforcement function located?

the network gateway
PCEF provides policy enforcement as well as charging functionalities. Located at the network gateway, the PCEF performs the role of a traffic controller distributing appropriate bandwidth as and when required.

What is PCRF used for?

Policy and charging rules function (PCRF)—policy equipment for bandwidth and charging on multimedia networks—supports service data flow protection, policy enforcement and flow-based charging.

What is PCC in telecom?

“Policy and Charging Control Technology” course focuses on a new architecture that enables a precise control of packet traffic and charging based on individual services accessed by the users.

What is policy control in telecom?

Also called Integrated Policy and Charging Control. Policy management enables operators to dynamically control network resources with real-time policies based on service, subscriber or usage context.

What is PCRF in EPC?

Policy and Charging Rules Function (PCRF) is the part of the Evolved Packet Core (EPC) that supports service data flow detection, policy enforcement and flow-based charging.

What is the difference between PCRF and PCF?

Cisco PCF is an evolution from Cisco Policy and Charging Rules Function (PCRF) on the existing Cisco Policy Suite Cloud Native Docker container-based platform. In the 5G network, PCF has the following features and functions: Support 5G QoS policy and charging control functions and the related 5G signaling interfaces.
