UPF in 5G Network
UPF stands for "User Plane Function". It is a key component of the 5G core network architecture.
It handles the forwarding and routing of user data traffic between the access network (e.g., 5G base stations) and external data networks. And it performs various packet processing tasks, such as packet routing, packet filtering, and traffic detection.
The UPF ensures the appropriate QoS treatment for user data flows, and applies the necessary policy and charging rules for user data flows, as instructed by the Session Management Function (SMF).

5G Core Network Architecture
In this post, we will learn 5G Network Architecture. The control plane in 5G network includes the AMF, the SMF, the AUSF, the UDM, and the PCF. While the user plane includes the UPF. The control plane is not including those network functions only, there are another network functions in the control plane, that will be discussed later. In…

What is 5G CUPS in 5G Network ?
In this post we will learn what is 5G CUPS. CUPS refers to "control plane and user plane separation". 5G CUPS means that the 5G network is separated into "control plane" and "user plane". In order to understand CUPS, first we should know that in order for the UE to be able to exchange user…

5G Network Slicing
5G Network Slicing means that, to divide the physical network that the operator is having, into different logical networks with different characteristics. Every logical network, is a network slice. And every network slice has different characteristics from the other network slices, so that it can serve a certain type of services accordingly. Every network function…
