What is TDF in 3gpp?
The TDF, Traffic Detection Function, is ‘is a functional entity that performs application detection and reporting of detected application and its service data flow description to the PCRF’.
What is TDF in 4g?
Traffic Detection Function (TDF) is a network function that enforces traffic policies in real-time based on either pre-set rules or rules determined dynamically by the policy control rules function (PCRF) engine.
What is TDF in EPC?
TDF is Traffic Detection Function which was introduced together with Sd reference point as means for traffic management in the Release 11. The Sd reference point is used for Deep Packet Inspections (DPI) purposes.
What is the difference between PCEF and PCRF?
PCEF system is part of PCRF which is shown in the figure-1 and figure-2. PCEF is situated inside PDN GW (Packet Data Network Gateway) or in short PGW. The major difference between PCRF and PCEF is that PCEF does support offline and online charging interactions while PCRF does not support these.
What is control and user plane?
Control plane is protocols for which controlling the radio access bearers and the connection between the UE and the network and User plane is responsible for the transfer of user data, such as voice or application data through the access stratum.
What is 5G user plane and control plane?
The control plane carries the signaling traffic, the user plane the user data (which is the content of communications), and the management plane the administrative traffic.
What is Pcef in telecom?
The PCEF is a DPI (Deep Packet Inspection) device responsible for the enforcement of rules which have been configured statically or supplied to the PCEF dynamically from the PCRF (Policy and Charging Rules Function).
What is 5G user plane?
The 5G User Plane Function (UPF) is the function that does all of the work to connect the actual data coming over the Radio Area Network (RAN) to the Internet.
What is UPF in 3GPP?
The User Plane Function (UPF) is a fundamental component of a 3GPP 5G core infrastructure system architecture. CUPS decouples Packet Gateway (PGW) control and user plane functions, enabling the data forwarding component (PGW-U) to be decentralized.
What is C plane and U plane?
To facilitate the mobility of heterogeneous networks, control plane (C-plane) and user plane (U-plane) decoupled architecture is being considered by the fifth generation (5G) wireless communication network, in which relatively crucial C-plane is expanded and kept at dependable lower frequency bands to guarantee …
What is TDF in 3GPP?
TDF was introduced together with Sd reference point as means for traffic management in the Release 11 3GPP specifications using Layer-7 traffic identification. TDF is deployed to manage the complexities in managing data services and addressing the demand for personalization and service differentiation.
What is TDF (transient data flow detection)?
TDF enforces traffic policies based on pre-set rules or dynamically determined rules by the PCRF on data flows in real time. TDF was introduced together with Sd reference point as means for traffic management in the Release 11 3GPP specifications using Layer-7 traffic identification.
What is TDF and how does it work?
TDF provides Communication Service Providers (CSPs) an opportunity to capitalize on analytics for traffic optimization, charging and content manipulation, working hand in hand with policy management (PCRF) system. TDF enforces traffic policies based on pre-set rules or dynamically determined rules by the PCRF on data flows in real time.
How to test PCRF with TDF simulation?
Test the capacity and performance of your PCRF with TDF simulation. The Sd reference point is stateful. Use the PCRF Emulator and the Sd Interface application in tandem to test Diameter Routing Agents (DRA) , Proxies, Relay Agents, and Redirect Agents.
