The central node for call routing and management.

The GSM network architecture is divided into three primary subsystems that manage communication, switching, and operations:

Uses the Subscriber Identity Module (SIM) to store unique identity information. Security is maintained through a challenge-response authentication mechanism and over-the-air encryption using algorithms like A5. GSM – Architecture, Protocols and Services

The Global System for Mobile Communications (GSM) is the foundational standard for second-generation (2G) digital cellular networks. It was developed to provide a unified digital mobile system that facilitates seamless international roaming and secure voice and data services.

Verifies user identities and provides security keys for encryption. The central node for call routing and management

A temporary database storing information for subscribers currently roaming in its area.

A permanent database containing subscriber profiles and their last known location. The Global System for Mobile Communications (GSM) is

Often called the core network, it performs call switching and manages subscriber mobility. Key components include:
