SGW in 4G-LTE Telecom Network
SGW stands for "Serving Gateway". It is a key component of the Evolved Packet Core (EPC) architecture in 4G LTE networks.
It serves as the anchor point for user plane data packets, it routes and forwards user data between the eNodeB (Evolved Node B), and the Packet Data Network Gateway (PGW).
Also it coordinates with the Mobility Management Entity (MME), to handle handovers between different eNodeBs, ensuring seamless connectivity for the UE.
In addition, it ensures the appropriate QoS treatment for user data flows, based on the subscriber's service requirements.
The SGW interacts with other key network elements, such as the MME, PGW, in order to perform its functions.

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…

Your Guide to LTE Interfaces (S11, S5, S8, SGi, S1-U)
Let's talk about LTE Interfaces. In LTE, every interface between two network nodes, is having an interface name, that represents the protocols used in the communication between those nodes. Below graph shows LTE Interfaces that exist between different nodes, In order to understand LTE Interfaces, we need first to understand the difference between the control…

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…
