What does PCRF in LTE mean?

Policy and Charging Rules Function
Policy and Charging Rules Function (PCRF) is a node which functions 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/LTE.

What is the difference between PCF and PCRF?

The Policy and Charging Rules Function (PCRF) has become an important functionality in the 4G networks with the advent of the VoLTE service. One of these NFs is the Policy Control Function (PCF) which will handle User Plane resources for the 5G sessions – it is therefore a natural continuation of the 4G PCRF.

What is the interface between PGW and PCRF?

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. Operational and maintenance interface, used to manage the device. Interface between the PGW and any packet data network.

What is LTE HSI?

HSI (High Speed Synchronous Serial Interface) is a high-speed communication interface. It offers a high-speed multichannel interface to connect 3G and 4G (up to LTE or Long Term Evolution Category 3) modems.

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 PCF in 5G?

Oracle Communications Cloud Native Core, Policy Control Function (PCF) helps operators to easily create and seamlessly deploy policies in a 5G network.

What are LTE interfaces explain?

Explaining the Interfaces in LTE: Within an LTE network, LTE Interfaces connect the various components to or within the core. Interfaces allow the MME, SGW and PGW to cooperate with other network elements (e.g. HSS or PCRF). Each one of them is built in a standard way described by 3GPP.org.

Why is PCRF important in 4G LTE network?

Apart from this, PCRF LTE also has the functionality to make it easy for other devices out of the 3GPP network- like WiFi or fixed broadband devices- to access the 4G LTE network. In other words, PCRF LTE is the policy manager of the new 4G LTE technology.

Which is an important capability of the PCRF?

PCRF solution shall provide the following key capabilities as listed below: Network Control: The PCRF provides network control regarding the service data flow detection, gating, QoS and flow based charging (except credit management) towards the PCEF (e.g., SAE-GW, PDN GW).

Which is PCC rule for LTE Hsi service?

For LTE HSI service, any one of the PCC rule (Dynamic or Predefined) will be installed according to the requirement. PCRF uses the subscriber profile in the SPR and install the rule based on subscriber profile. The following important parameters will be considered by PCRF.

What are the dynamic PCC rules of the PCRF?

Dynamic PCC rules: Dynamically provisioned by the PCRF to the SAE-GW via the Gx interface. Dynamic PCC rules can be activated, modified and deactivated at any time. Predefined PCC rules: These rules are preconfigured in the SAE-GW. Predefined PCC rules can be activated or deactivated by the PCRF at any time.
