About this network diagram for 4G
The following network diagram for 4G is a visual representation of the 4G architecture in terms of the interrelationships and connectivity of the components. It is concerned with the data and control information flow between those components illustrating what happens in a 4G system. Each component has its name and position. This shows its effect on the system. So, the diagram is ideal for explaining how 4G systems work.
At the lower-left corner, the user device is linked to the network using the eNodeB, the 4G base station. The user plane transmits user data. The control plane allows signaling. As such, the eNodeB provides access to the 4G managed core network both for the user and the control plane.
Inside the core network, various functional blocks are illustrated. The MME (mobility management entity) takes charge of signaling, manages mobility and authenticates users. This component looks after the most important aspects of communications – the user device and the network are always connected.
Another important system is the HSS (home subscriber server) responsible for keeping track of all users and their active subscriptions. Its link with the MME is vital for allowing users who are only authenticated to access the network effectively.
The serving gateway (SGW) is key. It transports data across the core network. It connects the eNodeB and the packet gateway (PGW). The PGW connects the internal network to the external network. It forwards data packets between the core network and the internet. The flow of this data is shown in the diagram using arrows indicating their direction while the user and control planes have also been defined.
The network diagram also shows how the 4G network is structured simply and easily. The distinction between user and control planes enhances traffic management as well as signaling. The core network elements are MME, HSS, SGW, and PGW. They are integrated to improve connectivity and communication quality.
The network diagram for 4G fills out the picture of how the system is organized focusing on the relationship of the major components. This diagram is simple and clear. It shows how 4G networks work. It depicts how each part contributes to the effective transmission of information.
