What is a telecom core network?

A Telecom Core Network is the central part of a telecommunications system that manages and routes voice, data, and other services between users and external networks. It is responsible for essential functions such as call control, authentication, charging, and mobility management. The core network connects the access networks (like cell towers) to external networks, ensuring seamless communication. With the evolution to 4G and 5G, the core network has become more software-based, supporting faster speeds and new services. Professionals in this field work on maintaining, optimizing, and upgrading these critical systems.
