SMF in 5G Network
SMF stands for "Session Management Function". It is a key component of the 5G core network architecture.
It establishes, maintains, and releases user sessions in the 5G network. And it coordinates the allocation, modification, and release of IP addresses and other session parameters for user equipment (UEs).
The SMF selects the appropriate User Plane Function (UPF) to handle the user's data session.
And it configures the UPF to apply the necessary Quality of Service (QoS) parameters, and traffic handling policies, such as packet routing, traffic detection, and usage monitoring.

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 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…

LTE (4G) Network Architecture
LTE (4G) Network Nodes LTE refers to 'Long Term Evolution', and the architecture of the LTE (4G) network is as following, eNodeB The eNodeB is the 4G site that the UE connects to. It provides the radio interface to the UE. MME MME refers to 'Mobility Management Entity'. The MME is responsible for authenticating the…
