HLD (High Level Design) and LLD (Low Level Design) in Mobile Networks
HLD (High-Level Design) and LLD (Low-Level Design), are two important terms in mobile networks design. They are essential for ensuring the successful design, implementation, and deployment of mobile networks
The HLD is the initial stage of the network design process. It focuses on the overall system architecture, defining the major components, their interactions, and the high-level functionality of the network.
It includes many information such as, network topology, core network elements, network interfaces and protocols.
While the LLD is the more detailed, technical stage of the network design process. It translates the high-level architectural decisions into a concrete, implementable plan for the network.
It typically includes information such as detailed hardware and software specifications, network element configurations and settings, deployment and integration procedures.

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…

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…

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…
